A clamp for supporting medical stent pipe

Abstract

The invention discloses a clamping fixture for supporting medical stent tubing. The clamping fixture comprises a whole rotating shaft mounted on an operating board, a clamping head mounted at one end of the whole rotating shaft, and a parallel two-finger clamping mechanism manufactured by adopting magnesium alloy with outstanding vibration reducing performance, wherein the parallel two-finger clamping mechanism is mounted on the operating board and comprises parallel two-finger clamping forceps, a bushing, and a bushing seat for placing the bushing. The clamping fixture for supporting the medical stent tubing, which is disclosed by the invention, has functions of vibration absorption and reduction, so vibration of the tubing, which is produced during the cutting, is reduced, a cut stent satisfies the precision requirement of a client, and the problems that the existing clamping fixture for clamping the stent tubing cannot well absorb and reduce the vibration, and since the stent tubing is easy to wear, destructive damages which cannot be polished away in the follow-up process are formed in the cut stent are solved.

Description

technical field [0001] The invention belongs to the technical field of laser micromachining of thin-walled pipes, in particular to a clamp for supporting medical stent pipes used in laser micromachining of medical stents. Background technique [0002] A medical stent is a metal mesh structure implanted into a vascular lesion to improve the blood flow in the lesion and support the blood vessel. Due to the simple process and fast speed, laser cutting has the advantages of small slit width, good incision parallelism, small surface roughness, high dimensional accuracy, small workpiece deformation and small heat-affected zone, etc., and can accurately cut micro-parts with complex shapes. The main processing method of medical stent processing. Medical stents are generally implanted into the diseased part of the blood vessel through interventional surgery, and finally bonded to the inner wall of the blood vessel. Therefore, there are strict requirements on the surface finish of th...

AI Technical Summary

Problems solved by technology

However, if pure rubber pads are used, because the pure rubber material is too soft to absorb vibration, it tends to increase the degree of vibration. At the same time, the rubber will gradually age and harden, thus losing the ability to reduce vibration; When block, because the metal material is too hard, it can not absorb the vibration to protect the pipe

It can be seen that metal, plastic or pure rubber clamps that are softer than medical bracket pipes will have problems such as vibration and abnormal noise, and the vibration reduction and vibration absorption effects are not good.
