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.
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
