Acetabulum posterior wall steel plate

Abstract

The invention discloses an acetabulum posterior wall steel plate which comprises an acetabulum posterior wall fixing plate part fixed on the acetabulum posterior wall, and the acetabulum posterior wall fixing plate part has a shape of strip arc; screw holes are arranged on the acetabulum posterior wall fixing plate part, and an ischium body fixing plate part is connected to one end of the acetabulum posterior wall fixing plate part ; the ischium body fixing plate part of is bent toward the outer side of the arc of the acetabulum posterior wall fixing plate part; and screw holes are arranged on the ischium body fixing plate part. The steel plate can be used for quickly and effectively fixing the fractures on the acetabulum posterior wall position and the ischium body position to avoid the steel plate shaping phenomenon caused by a doctor in a clinic operation so as to improve the success rate of the operation.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to a steel plate for the posterior wall of the acetabulum. Background technique [0002] It turns out that in clinical practice, no matter where the pelvis is fractured, the pelvic plate is used. During the operation, the pelvic plate is shaped to achieve the required shape of the plate. Because of the special anatomical structure of the pelvis, it is very difficult to shape the plate. Takes a lot of time. In clinical practice, pelvic surgery is difficult, and the difficulty lies in the difficulty of repositioning and shaping with steel plates! For a pelvic fracture, the patient loses a lot of blood, and the operation must be performed with a large amount of blood transfusion to maintain the operation, but it cannot last too long, otherwise the patient's life will be in danger. Excessive pre-bending of the steel plate will lead to metal fatigue of the internal fixation product. C...

[0002]Originally, in clinical practice, no matter which part of the pelvis is fractured, a pelvic plate is used. Due to the special anatomical structure of the pelvis, it is very difficult to shape the steel plate, and it takes a lot of time

In clinical practice, pelvic surgery is difficult, and the difficulty lies in the difficulty of repositioning and shaping with steel plates! Pelvic fracture, the patient lost a lot of blood, and the operation must be performed with a large amount of blood transfusion to maintain the operation, but the time should not last too long, otherwise the patient's life would be in danger

Excessive pre-bending of steel plates will lead to metal fatigue of internal fixation products
