Pelvic fracture reduction device and operating method

Abstract

The invention relates to a pelvic fracture reduction device and an operating method. The pelvic fracture reduction device comprises a near end reduction mechanism, a far end reduction mechanism and aconnecting rod, wherein the near end reduction mechanism comprises a first frame body and a first positioning assembly which is mounted on the first frame body and used for fixing skeleton at the nearend of the affected side; the far end reduction mechanism comprises a second frame body, an adjusting frame body which is hinged to the second frame body, a second positioning assembly which is mounted on the second frame body and used for fixing the skeleton at the far end of the affected side, a third positioning assembly which is arranged on the adjusting frame body and used for fixing the skeleton at the far end of the affected side; and the first frame body is connected with the second frame body through the connecting rod. Through the adoption of the pelvic fracture reduction device disclosed by the invention, the effect that after pelvic fracture and displacement occur, the skeleton at the far end of the affected side and the skeleton at the near end of the affected side are in reduction closing through the in vitro reduction device is realized; the reduction accuracy is high; the recover speed of a patient is high, the skeleton recovery effect is better, and besides, the situation that a large-range of scar is left through cutting open a fracture site is avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a pelvic fracture reduction device and an operation method. The pelvic fracture reduction device is applied to the fracture reduction of the superior pubic ramus of the pelvis or the anterior column of the acetabulum. Background technique [0002] Fractures of the superior pubic ramus of the pelvis and the anterior column of the acetabulum are common clinically. Different treatment methods can be adopted depending on whether the broken bone is displaced, including: [0003] 1. Percutaneous closed nailing with the assistance of X-ray or surgical robot; the treatment method of percutaneous nailing is non-invasive, and it is an ideal fixation method for fixing fractures of the superior pubic ramus of the pelvis or anterior column of the acetabulum. [0004] 2. Open reduction and internal fixation with steel plates; cut open the fracture site, perform reduction, and then p...

AI Technical Summary

Problems solved by technology

[0005] In the above two treatment methods, because the fracture of the superior pubic ramus of the pelvis and the fracture of the anterior column of the acetabulum are usually caused by high-energy injuries, most of the broken bones will be displaced

Moreover, it is difficult to perform closed reduction of the broken bone due to the abundant surrounding muscles, nerves and blood vessels wrapped and entangled.

Existing surgical robots can only assist in screw placement, but cannot reset fractures

Therefore, percutaneous nailing is only suitable for non-displaced suprapubic ramus / column fractures of the pelvis

However, the method of open reduction and internal fixation will cause a large wound and leave obvious scars
