It has the characteristics of easy implantation, strong fixation force and difficult ligament falling off.

Description

Tendon and ligament fixation tablet structure

technical field

The utility model relates to a bone, joint and ligament fixation device, in particular to a tendon and ligament fixation pressing sheet structure used for fixing after tendon and ligament avulsion fracture.

Background technique

Clinically, the tear or avulsion fracture of the bone and joint ligament is a very common disease. The existing treatment method is to compress and fix the ligament bone fragment at the tear site to the fracture site through a single fixation tablet. This single fixation Compressing the tablet is to compress the ligament by tightening the tension wires at both ends of the tablet. Most of the force is concentrated on the two ends. The compressing force in the middle part is limited and the range is single. However, the middle part needs to be compressed during treatment. A single fixed pressing piece is likely to cause loosening of the fixation, thereby causing the ligament to fall off from the fixation place.

Contents of the invention

The utility model aims to provide a tendon and ligament fixing pressing tablet which has a large fixing force and the ligament is not easy to fall off, so as to overcome the deficiencies of the prior art;

The technical scheme that the utility model realizes its purpose is;

A tendon and ligament fixation pressing sheet structure, which includes: a base sheet, the two ends of the base sheet have compression pull wire holes, and its innovative point is that: one side of the middle part of the base sheet is hinged with a locking sheet, so Reinforcing piles are distributed on the locking piece, and counterbores are arranged on the substrate corresponding to the reinforcing piles.

One end of the locking piece also has a compression pull wire hole.

After the above technical solution is implemented, since one side of the middle part of the base plate is hinged with a locking piece, reinforcing piles are distributed on the locking piece, and counterbores are provided on the base piece corresponding to the reinforcing piles. Through the adjustment of the locking piece, the locking piece can be tightly attached to the bone, and the reinforcement pile can increase its gripping force, and then fasten it with the tension rope through the tension cable hole to achieve a good compression The role of tendons and ligaments.

Detailed ways

Below in conjunction with accompanying drawing, through the description of specific embodiment, the utility model will be further described.

For specific implementation, please refer to accompanying drawings 1 and 2.

A tendon and ligament fixing sheet structure, which includes: a base sheet 1, the two ends of the base sheet 1 have compression pull wire holes 2, and it is characterized in that: one side of the middle part of the base sheet 1 is hinged with a lock through a hinge 4 A tightening piece 3, reinforcing piles 6 are distributed on the locking piece 3, and counterbores 5 are provided on the substrate 1 corresponding to the reinforcing piles 6. In the utility model, since the locking piece 3 is hinged on the base piece 1, the angle of the locking piece 3 can be adjusted for different bones so that it fits closely with the bone, tendon and ligament, and then the reinforcing pile 6 goes deep into the tendon and ligament , which ensures more stability. At the beginning of the operation, the locking piece 3 is folded on the base piece 1, and the reinforcing pile 6 is just inserted into the counterbore 5, which reduces the size of the utility model and can easily enter the patient's body, and then unfold it for use , so that it fits the bones, tendons and ligaments.

One end of the locking piece 3 also has a compression pull wire hole 2 . The utility model binds and fixes the base piece 1 and the locking piece 2 after the tensioning rope passes through the tensioning wire hole 2, which ensures a good fixing effect.

The utility model can increase the pressure on the middle part of the substrate through the locking piece, so that the ligament is not easy to fall off. The utility model has the characteristics of simple operation, large fixing force, and the ligament not easy to fall off.
