Problems solved by technology

[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

Embodiment Construction

[0011] The present invention will be described in further detail below through specific examples.

[0012] A posterior acetabular column plate such as figure 1 As shown, the steel plate is elongated, including a spoon 1 for fixing on the posterior column of the acetabulum and a handle 2 for fixing on the ischial body, and the spoon 1 and the handle 2 are uniformly arranged There are several screw holes 3 . The connecting parts between the screw holes 3 and the screw holes 3 are concave neck-shaped connecting parts.

[0013] The curve of the spoon portion 1 is designed according to the physiological curve of the posterior column of the acetabulum of an ordinary human body. When performing surgical treatment on different patients, although the profile curves of the posterior column of the acetabulum of each patient are different, the general shape is the same. Almost, in this way, the doctor only needs to shape the steel plate a little, and it can fit well with the patient's ...

Abstract

The invention discloses a steel plate for a posterior column of acetabulum. The steel plate is elongated, and comprises a spoon part which is fixed on the posterior column of acetabulum and a handle part which is fixed on corpus ossis ischii; and the spoon part and the handle part are uniformly provided with a plurality of screw holes. The steel plate for the posterior column of acetabulum is arranged according to a curve between the posterior column of acetabulum and corpus ossis ischii, is needed to be slightly shaped to be used in surgery, gains surgical time for a patient and improves the success rate of surgery.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to an acetabular posterior column steel plate. 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. Contents of t...
