Pelvic fracture posterior ring minimally invasive stabilization system guide plate

Abstract

The invention discloses a pelvic fracture posterior ring minimally invasive stabilization system guide plate. The guide plate comprises a rear guide plate and a side guide plate; the rear guide plateis connected with the side guide plate; fixing holes are formed in the rear guide plate and the side guide plate; each fixing hole is used for implanting a Kirschner wire; the rear guide plate and theside guide plate are fixed through the Kirschner wires; and the rear guide plate comprises an LC2 channel screw guide pipe, and the side guide plate comprises a sacral 1 channel screw guide pipe anda sacral 2 channel screw guide pipe. According to the pelvic fracture posterior ring minimally invasive stabilization system guide plate, the combined design is adopted, the guide plate is divided into two parts, the guide plate is embedded through the two minimally invasive incisions, and the channel is established under muscles for combination. Compared with an existing guide plate scheme, the trauma is smaller.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a 3D printed guide plate for a minimally invasive stabilization system for the posterior ring of a pelvic fracture. Background technique [0002] Fractures of the posterior pelvic ring (sacral fractures, ilium fractures, etc.) can be internally fixed in a variety of ways. Studies have shown that screw fixation has biomechanical advantages and less trauma. Therefore, for patients with posterior pelvic ring fractures with surgical indications, At present, channel screws are mostly used for internal fixation. [0003] Traditional surgical operations need to be monitored by a C-arm X-ray machine. By constantly changing the special projection position of the C-arm, according to the adjacent relationship between the bone and the joint and the Kirschner wire displayed on the C-arm, the needle insertion point and direction are adjusted to avoid During the insertion of the Kirs...

AI Technical Summary

Problems solved by technology

The main shortcomings of the traditional surgical operation method: 1. The needle insertion point and needle insertion direction planned before the operation cannot be positioned during the operation. During the operation, it is necessary to repeatedly adjust the needle insertion point and needle insertion direction, as well as repeatedly adjust the C-arm and projection position. Medical staff and patients suffer more radiation exposure

2. It is difficult for the screw to reach the path and position planned before surgery

3. The exposure time of the operation is long, and the position of the C-arm is changed repeatedly, which increases the risk of postoperative incision infection
