Combined internal fixator for fixing laparoscopic gastric banding

Abstract

The invention relates to a combined internal fixator for fixing laparoscopic gastric banding. The combined internal fixator is characterized by comprising a T-shaped bone fracture plate, a bone fracture plate for posterior acetabular wall dissection, a locking combined screw, a minitype screw and a fastening screw, wherein the T-shaped bone fracture plate and the bone fracture plate for posterior acetabular wall dissection are fixed by virtue of the locking combined screw; the longitudinal section of the T-shaped bone fracture plate is provided with a locking combined hole; multiple minitype screw holes are uniformly distributed in the transverse section of the T-shaped bone fracture plate; the minitype screw passes through the minitype screw holes so as to fix the T-shaped bone fracture plate to a skeleton; multiple holes are uniformly distributed in the bone fracture plate for posterior acetabular wall dissection, the hole at the middle of the bone fracture plate for posterior acetabular wall dissection is a locking combined hole, the holes at two ends of the bone fracture plate for posterior acetabular wall dissection are fixing holes, and the fastening screw passes through the fixing holes as to fix the bone fracture plate for posterior acetabular wall dissection to the skeleton. The combined internal fixator is unlikely to slide, is capable of adjusting the structure as required and is good in fixation effect.

Description

technical field [0001] The invention relates to a combined internal fixer for fixing acetabular posterior wall fractures. Background technique [0002] Posterior acetabular wall fractures are the most common of all acetabular fractures and are often the result of high-energy instrument panel injuries, often associated with hip dislocation. Its diagnosis and treatment are relatively easy. Due to intra-articular fractures, the curative effect after surgical treatment is not satisfactory. There are many factors that affect the curative effect. How to reduce surgical trauma, shorten operation time, and reduce the incidence of surgical complications while effectively reducing and fixing, so as to promote fracture healing has always been the focus and difficulty of orthopedic surgeons. [0003] Reconstructing bone plate fixation firstly needs to bend and plasticize the fixator to a large extent during the operation, which is complicated and takes a long time. At the same time, ...

AI Technical Summary

Problems solved by technology

However, due to single-plane fixation, the fixation effect is poor, and the fracture block is unstable: the most significant disadvantage is that it is easy to cause further fragmentation of the fracture block, and the risk of screw protruding into the joint is high; and the requirements for the operator are high, and repeated operations are required. Perspective observation; at the same time, during postoperative functional exercise, the screws are easy to slip due to lack of support and protrude into the inside or outside of the joint, etc.
