Processing equipment for minimally invasive scalpels

Abstract

The invention discloses a machining device for a minimally invasive scalpel. A round slotting tool of the device is parallelly provided with a plurality of first line through grooves in the axial direction and a plurality of second line through grooves, wherein the first line through grooves consists of first front line grooves, first rear line grooves and first folding line grooves. The first rear line grooves are located on one side of each first front line groove extension line, wherein the first folding line grooves are connected with the head and tail ends of the first front line grooves and the head and tail ends of the first rear line grooves. The second line through grooves consist of second front line grooves, second rear line grooves and second folding line grooves, wherein the second rear line grooves are located on one side of each second rear line groove extension line, and the second folding line grooves are connected with the head and tail ends of the second front line grooves and the head and tail ends of the second rear line grooves. Blades are formed at the tail ends of the outer surfaces of a first elastic blade and a second elastic blade, and two sides of each first folding line groove and two sides of each second folding line groove are provided with side blades. The machining device for the minimally invasive scalpel can remove all of convex points in a whole inner wall region in one time, greatly improves the elasticity of the middle of a round slotting tool, effectively prevents excessive scratching and ensures the consistency of product performance.

Description

technical field [0001] The invention relates to the field of surgical knives, in particular to a processing device for minimally invasive surgical knives. Background technique [0002] In the prior art, minimally invasive surgery is welcomed by patients because of its small trauma, light pain and quick recovery. However, due to the limitations of equipment and conditions, the operation has high requirements for doctors, but the process is very difficult. [0003] After long-term processing, it was found that the defect rate of the outer aluminum tube sleeve of the minimally invasive scalpel has remained high, and most of the processed parts cannot meet the precision requirements. The main reason is that the extrusion material is poorly fed, and small bumps of 0.05MM~0.1MM often appear on the inner wall of the aluminum agent material. However, this phenomenon cannot be improved in the aluminum agent process and bumps cannot be avoided. Therefore, it is necessary to improve ...

AI Technical Summary

Problems solved by technology

[0004] The outer aluminum sleeve of this minimally invasive scalpel has a small inner wall diameter (5.86MM), and there is still a tolerance, and the inner wall has a special shape, and the special shape is very small (the width of the special shape is 0.7MM), and the ordinary method cannot make the inner wall small convex. point removal
