Fixation system for spinae scapulae during anatomy

Abstract

The invention provides a fixation system for spinae scapulae during anatomy. The fixation system includes a bone plate, wherein a head part and a stem part are arranged on the bone plate, the head part is fixed on the area, near acromion, of the side surface of the spinae scapulae, and the stem part is fixed on the area, close to the lateral border, of the side surface of the spinae scapulae; andhead locking holes are formed in the head part, stem locking holes are formed in the stem part, and axes of the head locking holes and axes of the stem locking holes are arranged obliquely along the normal of a bone plate body. A first surface and third surface of the bone plate body of the fixation system for spinae scapulae during anatomy can be fixed on the side surfaces of the spinae scapulae,and can fit the spinae scapulae, and no bending steps are needed during the surgery, so that surgical failure risks caused by inconsistency between the form of a bent reconstruction plate and the bone are avoided, and damage of bending work to the strength of the reconstruction plate is avoided; and meanwhile the surgery time is shortened, the bleeding amount is reduced, and infection risks caused by long-time exposure is reduced during the surgery.

Description

technical field [0001] The invention belongs to the field of surgical internal fixation, in particular to an anatomical scapular spine fixation system. Background technique [0002] Due to the dense and irregular shape of the muscles around the scapula, it is easy to cause fractures of the spine of the scapula under the action of gravity. The spine of the scapula is almost 90 degrees from the subscapular fossa. When the patient is lying on his back, the muscles around the spine of the scapula need to be in contact with the bed. Fixation on the top of the scapular spine is not conducive to the patient's recuperation. The bone thickness of the spine of the scapula is uneven, the top of the spine of the scapula is wider, the part of the spine of the scapula connected to the infraspinatus fossa is thinner, and the height from the spine of the scapula to the lateral edge gradually decreases, which is not conducive to the fixation of the spine of the scapula. For the fixation ope...

AI Technical Summary

Problems solved by technology

Since the reconstructed steel plate does not conform to the anatomical shape of the scapula, doctors often need to bend and shape the steel plate according to the shape of the scapula during the operation. This method has the following defects: 1. The bending operation reduces the strength of the steel plate and increases the fracture of the steel plate after surgery risk

2. Manually bending the steel plate can only roughly attach the steel plate to the spine of the scapula, and cannot fully conform to the anatomical shape of the scapula, causing irritation of the surrounding soft tissues and increasing the pain of the patient

3. The length of the spine of the scapula is limited, the number of screws fixed by the reconstruction plate is small, the fracture fixation is not firm, the postoperative recovery effect is poor, and the risk of fixation failure increases

4. Affected by the shape of the spine of the scapula, surgical exposure is difficult. The reconstruction plate fixed on the top of the spine of the scapula is not conducive to the patient’s recuperation, while the reconstruction plate fixed on the side of the spine of the scapula is limited by space, and it is difficult to insert screws in the horizontal direction after the reconstruction plate is attached to the spine of the scapula

5. The intraoperative bending operation is complicated, prolonging the operation time, increasing the amount of bleeding and the risk of infection
