Embodiment Construction

[0021] The soft tissue fixation device containing titanium nails described in the present invention will be further described below in conjunction with specific examples, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0022] In a specific embodiment, the titanium nail of the present invention is made of titanium alloy wire through spiral bending. The titanium alloy is composed of 5.5-6.0wt% Mo, 1.5-2.0wt% Zr, 0.3-0.5wt% Mg, 0.05-0.15wt% Nb, and the rest Ti. Through solution treatment, the tensile strength of the titanium alloy described in this embodiment can reach 820-900MPa, the yield strength can reach 800-850MPa, the elongation can reach 25-35%, and the fracture toughness can reach 85-90MPa -1 / 2 , has good ductility and toughness. During processing, the titanium alloy wire is subjected to micro-arc oxidation surface modification treatment, and...

Abstract

The invention relates to a titanium nail and a soft tissue fixation device containing the titanium nail, belonging to the technical field of medical equipment. The titanium nail provided by the invention is formed by spirally bending a titanium alloy wire material; a titanium alloy is prepared from 5.5 weight percent to 6.0 weight percent of Mo, 1.5 weight percent to 2.0 weight percent of Zr, 0.3 weight percent to 0.5 weight percent of Mg, 0.05 weight percent to 0.15 weight percent of Nb and the balance of Ti. The titanium alloy wire material is subjected to micro-arc oxidation surface modification treatment; adopted electrolyte is prepared from 1.5 weight percent to 2.0 weight percent of sodium citrate, 0.10 weight percent to 0.2 weight percent of sodium borate, 0.05 weight percent to 0.10 weight percent of glycine and the balance of water. The titanium nail provided by the invention has good mechanical property; especially, the titanium nail is subjected to special modification treatment, so that the titanium nail has the advantages of excellent corrosion resistance, less metal dissolution and good compatibility. The soft tissue fixation device containing the titanium nail provided by the invention is suitable for laparoscopic herniorrhaphy, and has the features of prevention from adhesion and convenience in operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, the invention relates to a titanium nail and a soft tissue fixation device containing the titanium nail. Background technique [0002] Incisional hernia (incisional hernia) refers to the hernia in which the internal organs or tissues of the abdominal cavity protrude from the abdominal incision. It is a common complication of laparotomy. Among them, the incidence of midline incision in the lower abdomen is relatively high, and it mostly occurs in the longitudinal abdominal incision area. Incisions with opening, infection, and secondary healing, a few occurred after a long time after surgery without a history of incision dehiscence. Its incidence rate can reach about 2-11%, and the incidence rate of incisional hernia after wound infection can be as high as about 40%. Abdominal wall incisional hernia is mainly treated with surgery. The current methods of repairing inc...
