Medical device execution end, interventional treatment system and use method of system

Abstract

The invention discloses a medical device execution end, an interventional treatment system and a use method of the system. The interventional treatment system includes the execution end, a handle operation end and a catheter part which is used for connecting the execution end and the operation end; the inner wall of a sleeve pipe of the execution end is internally provided with three tentacle channels, and each tentacle channel is internally provided with a tentacle in a penetrating mode; each tentacle has two states, in the first state, the tentacles are hidden in the tentacle channels in the sleeve pipe and are in a storage state, and in the second state, the three tentacles stretch out of the tentacle channels and expand outwards to form a layout shaped like a Chinese character 'Ping'; a guide pipe is arranged at the center of the sleeve pipe, a guide channel is formed in the guide pipe, and a hook-shaped part is arranged in the guide pipe. The system is ingenious in structure, can achieve the short-distance movement of a bracket, and brings convenience to the position restoration of the bracket.

Description

technical field [0001] Medical devices commonly used in the treatment of the cardiovascular system involve minimally invasive surgical procedures, for example, the closure of some ruptured arteries, the operation of aneurysms, and the like. Background technique [0002] Take coronary heart disease as an example. Coronary artery stent implantation is an effective method for the treatment of coronary heart disease. Coronary artery bifurcation lesions have the following three characteristics: 1. The main branch and the branch form an angle, and the opening of the branch vessel forms an inclined plane, and the angle between the main branch and the branch is different in size, resulting in the current stent technology cannot completely cover the lesion or multi-layer stent coverage Reasons; 2. The diameters of the main branch and branches are different, and the diameter varies greatly; 3. The diameter of the main branch is different before and after the bifurcation, and the leng...

Problems solved by technology

Coronary artery bifurcation lesions have the following three characteristics: 1. The main branch and the branch form an angle, and the opening of the branch vessel forms an inclined plane, and the angle between the main branch and the branch is different in size, resulting in the current stent technology cannot completely cover the lesion or multi-layer stent coverage Reasons; 2. The diameters of the main branch and branches are different, and the diameter varies greatly; 3. The diameter of the main branch is different before and after the bifurcation, and the length of the lesion before and after the bifurcation is different, which is likely to cause poor apposition of the proximal section of the main branch stent, and the bifurcation and beyond. Distal stent overdilation

[0003] In the process of stent implantation, the ideal mode is that the one-time implantation is accurate and successful. However, due to comprehensive factors such as the doctor's state, equipment, and environment, there may be problems with the guide wire, balloon or stent during the implantation process. Deviation, that is, the implantation point cannot completely coincide with the lesion site, resulting in the stent not being able to completely cover the lesion site, and the ideal effect cannot be achieved. Currently, there is no medical device specially designed to solve the above problems
