Pigeon chest and funnel chest integrated steel plate

Abstract

The invention relates to a pigeon chest and funnel chest integrated steel plate. The integrated steel plate comprises a steel plate body and a fixing piece, wherein the steel plate body comprises an arc-shaped main body part, a bendable part, a part which is provided with (screw) holes at two ends and is connected to the fixing piece, and an extension plate; the bendable part is a thin-layer steelplate and is arranged at the two ends of the arc-shaped main body, the thickness of the bendable part is smaller than that of the connecting part of the arc-shaped steel plate main body and the fixing piece, a thin-layer steel plate transition area is streamlined and is a chamfer round rectangle when seen from top to bottom, and the radius of chamfer is 1 / 4 to 1 / 3 of the width of the thin-layer steel plate; the thin-layer steel plate can rotate by more than 180 degrees around the arc-shaped main body; and in the using state, the fixing piece is located above the steel plate, and the fixing piece and the steel plate are fixed through guide screws. The steel plate is not easy to break off in the using process, the operation risk is remarkably reduced, the orthopedic effect is better, the operation is simpler and more convenient, and the steel plate can be more flexibly adjusted when the length of the steel plate is shorter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated steel plate for pectus pectus excavatum. Background technique [0002] Chicken breast is a chest wall deformity with an incidence rate second only to pectus pectus excavatum. Domestic and foreign literature reports that chicken breast accounts for about 5% to 20% of the incidence of anterior chest wall deformity. Chicken breasts not only affect the aesthetics due to their deformed appearance, causing serious psychological damage to the patients, but also cause the patient's sterno-ribs to protrude forward, resulting in reduced thoracic volume, limited lung expansion, and reduced lung tissue elasticity, which affects the development and normal function of the heart and lungs. [0003] In the surgical treatment of chicken breasts, in the past, sternal subsidence was often used, taking a longitudinal incision in the middle of the chest, freeing the soft tissue ...

AI Technical Summary

Problems solved by technology

In the course of clinical use, the inventor found that the above-mentioned steel plate would be broken during or after the operation, which seriously affected the smooth progress of the operation and brought the risk of reoperation to the patient; For the lower part, the surgical procedure is to peel off the corresponding rib periosteum and fix the fixed plate on the ribs first, then introduce the steel plate from the skin incision on one side to the incision on the other side, flatten the raised chest wall, and fix the plate on the ribs. The connecting part of the plate is docked with the fixed plate, and the two plates are fixed with screws. The inventor found that this operation mode weakens the correction ability of the steel plate and affects the surgical effect; moreover, although there are many models of the fixed plate to choose from, it can be used for The length of the steel plate can be adjusted in a large range, and the steel plate is slightly longer or shorter, which can be overcome by the selection of the fixation piece without affecting the operation. In addition, it is difficult to accurately align the fixation plate with the screw holes on the steel plate during the operation, and the operation of ordinary screw fixation is difficult, and the fixation effect is also poor
