Medical instrument hand shank operation end and interventional treatment system

Abstract

The invention discloses a medical instrument hand shank operation end and an interventional treatment system. The improvement is at the hand shank operation end, wherein gears are arranged in a gear box inside the hand shank, three gears are arranged in an equilateral triangle layout and at least part of them extend from the gap to the outer side of the hand shank, gear shaft holes are located in the center of the gears, central guide wires pass through a central guide wire channel in the hand shank then extend from an end cover to the outer side of the hand shank, a guide wire set passes through a guide wire set channel and the gear shaft holes in the hand shank then extends to the outer side of the hand shank, the guide wire set and the gear shaft holes are fitted in a threaded mode, three gears are meshed with a gear ring arranged in a sleeving mode on the outer side of the hand shank at the same time, the rotation of the gear ring drives the three gears to rotate synchronously. According to the medical instrument hand shank operation end and the interventional treatment system, the forward marching of the guide wires is controlled, the grabbing, moving and releasing actions of the support are achieved and can be achieved by one hand, the progress of the operation and the application of the hand shank are facilitated, so that the controllability is better and the accuracy is higher.

Description

technical field [0001] Medical devices usually used for cardiovascular system treatment will involve minimally invasive surgical therapy, for example, the occlusion of some ruptured arteries, the operation of aneurysm, etc. Background technique [0002] Take coronary heart disease, for example. Coronary stenting is an effective method for the treatment of coronary heart disease. Coronary bifurcation lesions have the following three characteristics: 1. The main branch forms an angle with the branch, the branch vessel opens into an oblique surface, and the angle between the main branch and the branch varies in size, resulting in the current stent technology unable to completely cover the lesion or multi-layer stent coverage Reasons; 2. The diameters of the main branches and branches are different, and the diameters vary greatly; 3. The diameters of the main branches before and after the bifurcation are different, and the length of the lesions in the anterior and posterior seg...

AI Technical Summary

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
