Processing device for medical device

Abstract

The invention discloses a processing device for a medical device. The processing device comprises a circular slotting cutter, a compressing mechanism, an ejector rod and the medical device; the medical device comprises an outer aluminum pipe casing, an inner pipe casing, blades, an elongated cutter handle and a cutter rod; a plurality of first line through slots and a plurality of second line through slots are axially formed in parallel in the circular slotting cutter; the first line through slots extend from one end surface of the circular inserting cutter to the middle part to form a plurality of first elastic blades, and the first elastic blades and second elastic blades form cutting edges at the tail end of the outer surface through an inclined surface; the compressing mechanism comprises a cylinder body, a piston and a tapered cover; the cylinder body is fixedly connected with the tapered cover; the piston is mounted between the cylinder body and the tapered cap; a first chamber is formed between the rear end of the piston and the cylinder body. With the adoption of the processing device for the medical device, small salient points can be cleanly and smoothly removed; the circular slotting cutter can be kept in contact with the inner wall of an aluminum pipe without any damage to the inner wall because of a certain elasticity; the small salient points on the inner wall can be removed to the maximum, and the effect is great; the processing device can be positioned to the inner wall and a long bar is operated to slightly poke to remove the small salient points.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a processing device for medical instruments. 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 the subsequ...

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
