Hand and Foot Surgical Fixation System Based on Magnesium-Based Alloy or Zinc-Based Alloy

Abstract

The invention discloses a surgical fixation system for hand and foot based on magnesium-based alloy or zinc-based alloy, which is characterized by comprising: a fixing unit and a bridge made of magnesium-based alloy or zinc-based alloy; A connecting portion is formed between two adjacent positioning portions, each positioning portion is provided with a positioning assembly, and each positioning assembly includes a suction cup disposed on the lower side of the positioning portion, a connecting column passing through the positioning portion and connected with the suction cup , cover, the connecting column is provided with perforations and side holes, the connecting part is provided with a connecting flow channel, a bridge flow channel is opened in the plate bridge, the connecting flow channel and the plate bridge flow channel are connected, and a rotary seal is formed on the plate bridge. The rotor, the rotor and the pump body are connected. The invention provides a hand and foot surgical fixation system based on magnesium-based alloy or zinc-based alloy, which omits the traditional screw fixation method, reduces the damage to the bone, and at the same time, avoids the need for secondary surgery to remove the alloy after implantation. the pain of surgery.

Description

technical field [0001] The invention relates to a surgical fixation system for hands and feet, in particular to a surgical fixation system for hands and feet based on magnesium-based alloys or zinc-based alloys. Background technique [0002] Nowadays, due to the increasing number of traffic accidents, the more unsafe living environment, the unreasonable diet structure, the general appearance of aging and other factors, hand and foot fracture accidents often occur. At present, steel needles or titanium plates and screws are usually used for fixation. For example, the existing Chinese utility model with the publication number CN208096811U discloses "a miniature hook-shaped locking titanium plate for intra-articular fracture fixation", which includes a body on which a working part for restraining fracture fragments is provided and a fixing portion for fixing the body on the backbone, the angle between the working portion and the body is 90°-120°, and the working portion includ...

AI Technical Summary

Problems solved by technology

This utility model uses titanium plate as the base material. Although the traditional titanium plate has excellent characteristics such as high strength, light weight, non-magnetic, non-toxic, good corrosion resistance and biocompatibility, the structure of the titanium plate cannot be degraded in the body. After the titanium plate structure is implanted in the first operation, after waiting for a long time for the wound to heal, it usually requires a second operation to remove it, which causes the patient to experience the pain of the second operation

At the same time, using screws to fix the titanium plate, because the screws need to be driven into the bone, the damage to the bone is greater
