The present invention relates to an operative titanium clip and a making method thereof. The operative titanium clip forms a V shape. A groove and across grains with certain width are arranged on the inner side of the operative titanium clip. The making method of the operative titanium clip comprises: preparing material, drawing wires to be molded, putting the material, heating A, molding, heating B, removing an oxidation layer, cleaning, acid washing, ultrasonic cleaning, disinfecting, drying, testing and packaging. Compared with the prior art, the present invention has the advantages and effects that structural design is reasonable, and the produced operative titanium clip has good holding performance and toughness.

Description

A kind of manufacture method of operative clip of titanium

Technical field:

The present invention relates to a kind of operative clip of titanium and preparation method thereof, be mainly used in the medical instruments field surgery Minimally Invasive Surgery and prick inner tubular structure for envelope in the implant into body.

Background technology:

Operative clip of titanium of the prior art inboard does not have groove and band, and the goodness of fit of operative clip of titanium and inner tubular structure is bad, is easy to generate to leak and offset phenomena, and gripping performance compares relatively poor.In addition, the manufacture method of former operative clip of titanium adopts one heat treatment step usually, causes the poor toughness of product, phenomenon of rupture takes place when pulling open easily, and the glossing in the traditional handicraft is unfavorable for the concordance of product processing dimension.

Summary of the invention:

Technical problem to be solved by this invention is to overcome above shortcomings in the prior art, and a kind of have good clamping and flexible operative clip of titanium and preparation method thereof are provided.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this operative clip of titanium, and the external form that it is characterized in that operative clip of titanium is a V-type, the inboard of operative clip of titanium is provided with the groove and the band of certain width.

Groove width of the present invention is 0.3 millimeter.

Band width of the present invention is 0.2 millimeter.

The present invention also comprises a kind of manufacture method of operative clip of titanium as mentioned above, comprises and getting the raw materials ready, the cleaning-sterilizing oven dry, test package, it is characterized in that after getting the raw materials ready further comprising the steps of: wire-drawing shape, blanking, heat treatment A, the profile molding, heat treatment B, the deoxidation layer cleans, pickling, ultrasonic waves for cleaning.

The present invention compared with prior art has the following advantages and effect: reasonable in design, the operative clip of titanium of producing has good clamping and toughness.
