Problems solved by technology

At present, the production of staples in the medical device industry is made by manual filing. This manual manufacturing process has the following defects: first, the daily output is low; second, the defect rate is high, and the defect rate is mainly reflected in the nail tip is not sharp and the nail body is deformed. Serious, burrs on the

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing. The numerical value of the angle involved in the present invention is the absolute value of the angle, and the positive and negative signs of the angle are omitted.

[0035] A staple preparation device includes a mandrel assembly 3, a mandrel support 4 and a broken nail die.

[0036] The staple is made of titanium wire 2, the material of which is pure titanium, and the specific grade is TA1 or TA2, wherein TA1 and TA2 are standard grades of pure titanium. Pure titanium has the appropriate hardness and toughness required by staples, and the staples made are not easy to be brittle. Use a winding machine to tightly wind the titanium wire 2 on the mandrel 1. The effect after winding is as follows: figure 1 shown. The meaning of the tight winding is: a titanium wire 2 is helically and continuously wound on the mandrel 1 by a winding machine, and the titanium wire 2 forms a cont...

Abstract

The invention relates to a preparation method of an anastomosis nail. A broken nail stamping knife in a broken nail stamp engages in compound motion to cut the titanium wires wound on a core rod at a certain angle. In such a way, a finished anastomosis nail can be obtained. The preparation method for producing anastomosis nails improves the yield, reduces the labor cost and solves the problems that the anastomosis nails produced in a manual manner are poor in consistency, the nail tips are blunt, the nail bodies deform, burrs exist on the head parts of the nails and that damages are caused to the nail bodies when the manual filing technique is adopted to produce the anastomosis nails.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for preparing staples. Background technique [0002] Staples are medical devices currently used in clinical medicine to replace traditional manual sutures. They can quickly suture human tissues after surgery, shorten tissue exposure time, reduce trauma and bleeding, and effectively reduce surgical complications. At present, the production of staples in the medical device industry is made by manual filing. This manual manufacturing process has the following defects: first, the daily output is low; second, the defect rate is high, and the defect rate is mainly reflected in the nail tip is not sharp and the nail body is deformed. Serious, burrs on the nail head and damage to the nail body, etc.; third, due to the use of manual filing, the file will often touch the mandrel wrapped with titanium wire, making the mandrel easy to wear and scrap. In order to select qual...
