FEP tubing and ptfe liner comparison of regarding adhesion

A, FEP tubing hot melt bonding can not?FEP chemicals: Tetrafluoroethylene-hexafluoropropylene copolymer or Fluororesin-46, abbreviation: FEP or F46 . F46 (FEP) is a copolymer of tetrafluoroethylene and hexafluoropropylene, which has good thermal stability, outstanding chemical inertness, excellent electrical insulation and low coefficient of friction, and can be processed by thermoplastic processing methods.F46 resin has similar properties to polytetrafluoroethylene, but also has good processing properties of thermoplastics.
The molecular structure of FEP, like PTFE, is also a fully fluorinated structure, the difference being that part of the fluorine atom of the F46 main chain is replaced by trifluoromethyl (-CF3).
Chemically: It is stable to almost all chemicals and solvents.
Thermally: PTFE, PFA continuous use temperature is 260 degrees, FEP continuous use temperature is 200 degrees
Mechanically: Minimal coefficient of friction and sealability
Electrical: Insulator with small dielectric constant and dielectric loss factor
Others: non-adhesive, weathering, flame-retardant, low temperature resistance
Invention process: PTFE -> FEP -> PFA
Hot fusion is generally used as a hot melt connection. The principle of hot fusion connection is to heat the flat end surfaces of two FEP tubing by pressing the mating surfaces against a heating tool until they are molten, and after removing the heating tool, the two molten end surfaces are pressed together and held under pressure until the joint cools, making the two sections of tubing connected into a single operation.
Note: FEP can only be made of FEP material and FEP hot fusion, same sex fusion, opposite sex repulsion .
FEP has similar characteristics to PTFE, but also has the good processing performance of thermoplastic. Thus, it makes up for the processing difficulties of PTFE, making it a material that replaces PTFE. It is widely used in wire and cable production for transmission wires of electronic equipment used at high temperatures and high frequencies, connection wires inside electronic computers, wires for the aviation universe and its special purpose installation wires, oil pump cables and insulation layers for winding wires of submerged oil motors.
Its main applications are for making inner villages of tubes and chemical equipment, the surface layer of drums and various wires and cables, such as aircraft hook-up lines, booster cables, alarm cables, flat cables and oil well logging cables. fep film has been seen used as a thin coating for solar collectors. It is mainly used in communication cables, electric wires, semiconductors, chemical anti-corrosion, medical materials, automobiles, industrial coatings and other fields.

Also can be used as corrosive liquid and gas transport tube, lining tube, tube for heat exchanger and liquid level meter. Also can be used as wire, cable and electrical components used in various frequencies

Teflon is commonly known as polytetrafluoroethylene (abbreviated as Teflon or [PTFE, F4]), which is also known as “Teflon”, , “Teflon”, “Teflon” and “Teflon”, “Teflon” and so on. It is a polymer compound made of tetrafluoroethylene by polymerization.
The color of polytetrafluoroethylene is milky white, and it can be produced in color, but the defect is that it cannot be made transparent. The alternatives to transparent are polyvinylidene fluoride (ptfe) and fep (soluble polyvinylidene fluoride). Teflon is a hose with a Shore hardness of D55.
Polytetrafluoroethylene tube is the use of high-quality plunger worker extrusion tube, using a special processing technology, so that the steel and plastic tube closely combined, can withstand positive pressure 1.6Mpa, negative pressure: 77Kpa; can be used normally within -60 ℃ ~ +260 ℃, with reliable and excellent corrosion resistance, conveying strong corrosive gas and liquid at high temperatures.
Polytetrafluoroethylene (PTFE) has excellent chemical stability, can resist all strong acids, strong alkalis, strong oxidants, and a variety of organic solvents do not occur. PTFE use a wide range of temperature, atmospheric pressure can be used for a long time -180 ℃ ~ 250 ℃, after processing at 250 ℃ high temperature 1000h, its mechanical properties change very little. PTFE has a very low friction factor, is a Its static friction coefficient is smaller than the dynamic friction coefficient, so it is used to make bearings with the advantages of low starting resistance and smooth running. Because PTFE is non-polar, heat-resistant and non-absorbent, it is an excellent electrical insulation material. It also has excellent aging resistance, non-stick and non-combustibility.
PTFE rods, tubes, films, bearings, gaskets, valves and other profiles and parts are widely used in machinery, chemicals, aviation, electrical and electronic, national defense industry, cutting-edge science and technology, medical and health care and electrical insulation and other fields.

What are the uses of FEP heat shrink tubing medical grade?

FEP Medical Tubing Applications

  • Insulin delivery tubes
  • Intravenous catheters
  • Epidural catheters
  • Urology catheter lines
  • Vascular access dilators, sheaths, and introducers
  • FEP Heat Shrink, used in the FLASH Catheter

FEP HS tubing is useful in medical solutions because of the solubility and ductility of the FEP material, which allows for the production of various forms of fluoroplastic tubing, and the high transparency of FEP tubing, which allows for the observation of internal fluid transport.

How does FEP HS tubing work ?

FEP Heat Shrink tubing medical grade, it is mainly used for interventional medical instruments. The larger the shrinkage ratio of FEP Heat Shrink tubing, the stronger the cladding effect.

Purchasing and selecting FEP Heat Shrink tubing medical grade ?

Considerations when purchasing FEP heat shrink ratio, wall thickness before and after shrink, production lead time and problems encountered in use are some of the factors that interventional medical device engineers often consider to determine and adjust specifications immediately.

As with many tubing components, the larger the heat shrink ratio, when the FEP hs tubing rheology, the tighter it will be wrapped, there will be no air bubbles, inflammation after the patient surgery, etc.. So the general selection of shrink ratio is 1.6 : 1 is the most cost-effective, because the selection of 2 : 1 production difficulties, low yield and higher costs; if you choose 1.3 : 1, it is possible that the wrapping is not comprehensive, shrinkage can not be, will bring the sequelae of subsequent medicine.

How classified vascular interventional surgical robots?

vascular interventional surgical robots classified

The vascular interventional surgery robot is the eyes, hands and brain of the doctor. Vascular intervention is an operational technique that uses instruments such as puncture needles, guidewires, (medical PTFE ETCH TUBING FEP HS PEBAX manufactured by AOKERAY provides high quality thin-walled medical tubing for this purpose) catheters for diagnosis and treatment via vascular pathways under the guidance of medical imaging. The procedure of vascular intervention is mainly divided into: puncture, access establishment, imaging, balloon pre-dilation, stent release, and withdrawal of guidewire catheter. Currently, the vascular interventional surgery robot can assist in most of the procedure steps, except for the trivial operations such as puncture and replacement of guidewires and catheters.
According to the functional classification, vascular interventional surgical robots can be divided into two categories: those that assist physicians in performing vascular interventional electrophysiological examinations or treatments, and those that assist physicians in completing angioplasty. The former requires the use of special vascular interventional instruments and the manipulation of active marker catheters and electrode catheters under magnetic navigation, while various types of intracavitary operations such as balloon and stent pushing cannot be performed; the latter is compatible with conventional interventional instruments such as smaller diameter catheters and guidewires, and can perform most of the operations in vascular interventional procedures without customizing special instruments.

According to the classification of application procedures, vascular interventional robots are mainly divided into three categories: coronary intervention, neurointervention, and peripheral intervention (including aortic intervention). Globally, coronary intervention is the most mature, with a large number of PCI (percutaneous coronary intervention) procedures each year, so most vascular interventional surgery robot companies are the first to apply their robots to PCI procedures.

Which development China’s vascular interventional surgery robot products in the future?

Which development China’s vascular interventional surgery robot products in the future?

1, covering the whole process of vascular interventional surgery and breaking through the dilemma of homogenization of surgical robot products. Some companies focus on intravascular operations, and product homogenization is serious. Intravascular operation is the core part of PCI surgery, and the existing surgical robot products may only function for a few minutes in the surgery, and the preliminary work of puncture, imaging and diagnosis still depends on the personal experience and technology of doctors. In interventional surgery, the angiographic and diagnostic process takes up 70-80% of the entire surgery time. These tasks are trivial and more difficult to standardize, but they can affect subsequent disease diagnosis and treatment.

With the rapid development of Aokeray China’s thin-walled medical tube customization, it plays a key role in driving the development process of vascular interventional surgery robots in China.

In order to cover more surgical processes, the vascular interventional surgery robot has to solve the problem of compatibility with different product models, flexibility, aseptic operation, and complete the whole process of unpacking, switching catheter guidewires, and recovery. Meanwhile, with the development of vascular interventional surgery robotic products, catheters, guidewires and other consumables are also moving toward a stage of intelligence and multi-functional integration. A catheter can achieve multiple functions, avoiding replacement during surgery and saving resources while improving efficiency.

2、Applicable to coronary intervention, peripheral intervention and neurointervention in multiple procedures, the pan-vascular surgery robot saves hospital procurement costs. Due to the high cost and expensive start-up fee of the vascular interventional surgery robot, the ideal product should adopt modular design and can carry out coronary interventional surgery, neurointerventional surgery and peripheral interventional surgery at the same time. The pan-vascular interventional surgery robot is equipped with a multifunctional platform inside, and the operator can choose the corresponding technical module by himself. In this way, the hospital can save a purchase cost. The surgical robot can be used with most commercially available guidewires, stents and balloons, and is compatible with existing catheterization laboratories, eliminating the need for custom-made specialized medical devices, facilitating in-hospital use and strengthening hospitals’ willingness to purchase.

Vascular interventional diseases have commonality, mainly obstruction, stenosis, thrombosis, and reflux, and interventional devices mainly include catheters, guidewires, stents, and balloons. In coronary intervention, the vascular interventional surgery robot needs to meet better precision and flexibility; in neurointerventional surgery, the surgery robot needs to meet fast and sterile replacement of consumables in addition to achieving high precision; while in peripheral interventional surgery, the precision requirement is relatively not high due to the large peripheral blood vessels, and the requirement for image navigation technology is higher. At the same time, peripheral interventions are less difficult and can be treated locally in grassroots areas, thus requiring high requirements for robot automation and the pursuit of balanced and stable surgical quality, as well as the cooperation of multiple departments in hospitals.
3, semi-automated or even fully automated vascular interventional surgery robots are the final form to further improve surgical efficiency and relieve physician fatigue. The main information source of automated surgery is medical images and case data, and the core technology is deep learning and feedback, which is indispensable for image processing, high precision and high response speed. At present, the image segmentation and fusion technology and feedback mechanism are not yet mature, so companies can start with the automation module.

4, 5G remote accelerates the popularity of robotic surgery, which is a unique advantage of Chinese enterprises. “In addition to relying on 5G technology with large bandwidth and low latency, hospitals need to build a high-quality 5G intelligent ecology. 5G remote surgery safety and stability are crucial, and in addition to network transmission problems such as latency and lag, they also need to pay attention to Online system operation failure, third-party online attacks and other extraordinary circumstances.
In clinical applications, an important application scenario for 5G telesurgery is emergency surgery. At present, 5G telesurgery is still in the clinical trial stage, and the problem of responsibility attribution needs to be solved in order to be carried out in the clinical environment. 5G surgery involves a total of three main responsible parties: hospitals, surgical robot companies, and network providers, and it is difficult to judge responsibility attribution if there are unconventional situations other than network delays and robot failures.

5, lightweight, miniaturization is conducive to reducing robot costs and improving accessibility. In addition to the original robot products by changing the design, materials to achieve lightweight, miniaturization, disposable vascular interventional surgery robot is another idea. The emergence of disposable robots may also change the high-end positioning of surgical robots with their high price and high maintenance costs.

The future of vascular interventional surgery robots can be systematic or specialized. The vascular interventional surgery robot products are in the exploration stage, and the above-mentioned technical directions can be developed simultaneously and are not completely isolated. The vascular interventional surgery robot market is blossoming, and there is no standardized path to break through from segmentation, improve the accuracy and standardization of operations such as imaging and guidewire catheter pushing, and deal with complex lesions such as calcified lesions and chronic complete occlusion; or to build a pan-vascular surgery robot and integrate more high-end performance from the product as a whole

PTFE liner in medical applications

Application of PTFE liner in ventral hernia repair case

Ventral hernia is the most common general surgery disease, and most of them are inguinal hernia, and surgical treatment is the accepted cure.

In 2021, a total of 859 tension-free hernia repairs were performed in our department, 767 cases (89.3%) in men and 92 cases (10.7%) in women. Among them, 731 cases (85.0%) were inguinal hernia, 86 cases (10.0%) were inguinal hernia, 13 cases (1.5%) were femoral hernia, 12 cases were incisional hernia, 9 cases were ventral white line hernia, and 8 cases were umbilical hernia. There were 27 cases of incarcerated hernia (no intestinal necrosis occurred), accounting for 3.1%.

All cases were treated with expanded polytetrafluoroethylene ptfe lined tubes manufactured by CHINA AOKERAY . The inguinal hernia procedure was performed according to the standard Lichtenstein procedure. For incisional hernia, white line hernia and umbilical hernia, the patch was placed in the peritoneum and in front of the posterior sheath, under the anterior sheath or under the skin according to the intraoperative situation after freeing and high ligation of the hernia sac, and all of them could heal in one stage. In femoral hernia, a transinguinal approach is used, after incising the tendon membrane of the external oblique muscle, the round ligament of the uterus, the internal oblique muscle and the joint tendon are drawn upward and outward to reveal the posterior wall, the hernia sac is found at the femoral ring and freed, the sac is incised and the contents are examined and returned to the abdominal cavity, the distal redundant sac is excised, the proximal end is tightly sutured and then turned inward, the transverse abdominal fascia is sutured, and then the patch is placed in the posterior wall, laid flat and sutured to the joint tendon, the pubic commissure ligament and the inguinal ligament. The patch was then placed in the posterior wall, sutured to the joint tendon, pubic comb ligament and inguinal ligament, and finally sutured to the outer layer of tissue and skin. The outer layer of tissue and skin were closed with 2-0 PROLENE sutures.   The average operating time was 95 min, and the longest hospital stay was 16 d, the shortest was 3 d, and the average was 4.6 d. The average follow-up period was 10-60 months, and the average was 30 months. 44 patients had postoperative complications, including 8 cases of urinary retention, 10 cases of postoperative hematoma or plasmacytoma, 4 cases of fat liquefaction in the wound, and 4 cases of incisional sinus tract (3 of which were partially removed and 1 of which was completely removed, all of which were related to There were 15 cases of scrotal swelling, 3 cases of mild postoperative pain, and no recurrent cases.

Tension-free hernia repair was first proposed by Lichtenstein in 1989 in the American Journal of Surgery and was regarded as a “milestone” in hernia repair in the 20th century. It is the best surgical approach for tension-free hernia repair today because it is a tension-free suture repair that maximizes the restoration of normal anatomical and physiological function of the patient’s organs and eliminates the anatomical basis for hernia recurrence, requiring only minimal suturing during surgery [1]. Polytetrafluoroethylene PTFE is completely fluorinated and specially treated expanded PTFE fibers can exhibit a porous structure that can be made into a soft, bendable, non-abrasive material. The greatest advantage of expanded PTFE liner is that it is flexible, the forces in all directions are in balance, it can be cut and covered as needed, presenting fiber continuity with a unique porous permeable microstructure into which cells can infiltrate, good histocompatibility, more superior mechanical properties, light postoperative wound pain for patients, small scar formation, better comfort, and is a tension-free hernia repair Ideal material

Who are the Microcatheter Market and Manufacturers in China?

The coronary microcatheters available in China can be divided into first-line working microcatheters with flat tip design, dilating/penetrating microcatheters with tapered tip design, dual-lumen microcatheters, and other innovative microcatheters.

First-line working microcatheters are the preferred clinical microcatheters, accounting for approximately 80% of the total microcatheter volume. The most classic first-line working microcatheter is the Finecross MG microcatheter from Terumo, Japan, which has a typical three-layer body design with a flat tip and is the most widely used first-line working microcatheter with the best overall clinical performance in China. It is difficult to pass through occluded lesions. As a result, the latest Finecross GT microcatheter, which is available in Japan, has a bluntly tapered tip, and there are no plans to market the Finecross GT microcatheter in China. In addition, APT launched its first domestic first-line working microcatheter, the Instantpass 1.9F microcatheter, in 2017, followed by companies such as Corech, Contrast, Boston Scientific, and Yeju, which have also launched their own first-line working microcatheters.

The other type of dilatation/through microcatheter with tapered tip design, represented by Tornus (now less commonly used) and Corsair from Asahi, Japan, has a pronounced taper at the tip, which greatly ensures the passage performance of the head end of the microcatheter, coupled with a coil spring reinforced body, and with rotational operation, the passage and maneuverability of the microcatheter are maximized. The Corsair Pro, an upgraded version of the Corsair, has now been licensed for entry into the Chinese market. The Corsair Pro significantly improves the tracking performance of the head end of the microcatheter by removing the metal markings on the head end. The main domestic dilatation/penetration microcatheter is APT’s Instantpass 2.6F microcatheter.

In addition, competition in the coronary microcatheter industry has intensified with the introduction of several innovative designs of microcatheters. Vascular Solutions, Inc. launched the Turnpike series of microcatheters in China in March 2021, which includes four different types of microcatheters: Turnpike, Turnpike LP, Turnpike spiral, and Turnpike gold. In the United States, the most commonly used microcatheters for the forward PCI route are Turnpike Spiral (18%) and Turnpike (16%); the most commonly used microcatheters for the reverse PCI route are Corsair/Corsair Pro (29%), Turnpike LP (26%), and Caravel (22%) [3]. Domestic Epter Med has also introduced the Instantpass 1.7F microcatheter, a reverse CTO tool with an outside diameter of only 1.7F and an effective length of 150/170 cm, which greatly meets the needs of reverse CTO procedures. In addition, Asahi’s Caravel microcatheter, which is known for its “thin stem and large lumen”, will soon be available in the Chinese market.

Dual-lumen microcatheters are currently in the early stages of discovery, with overall usage at about 1% of the total annual PCI volume. There are three brands of dual-lumen microcatheters currently available in China: Kaneka’s KDLC from Japan, Asahi’s Sasuke, and CoreTech’s Zhishuang from China. In addition, APT’s dual-lumen microcatheter is in the process of registration
