Description
Technical Field
The invention relates to the field of medical equipment for pelvic fracture surgery, in particular to an external fixing guide plate for accurately positioning pelvic fracture surgery.
Background
Pelvic fracture is one of the most serious injuries in trauma orthopedics, and is commonly seen in high-energy injuries such as traffic accident injury and high-altitude falling injury. The mortality rate of pelvic fracture is about 1/6 (5-30%), the mortality rate of closed fracture combined with hypotension is about 1/4 (10-42%), and the mortality rate of open fracture is about 1/2. Early uncontrolled massive bleeding is a major factor affecting mortality. Different hemostasis measures are required depending on the source of bleeding, but it is currently accepted that early recovery of pelvic volume is the most basic and effective measure. The method for restoring the pelvis volume comprises bed sheet binding in the pre-hospital (before entering a medical institution) treatment stage, a pelvis splint, a pelvis fixing belt, an external fixing support in the in-hospital emergency treatment stage and C-shaped fixing clamps. The C-shaped fixing forceps, also known as Ganz pelvis fixing forceps, are temporary fixing hemostatic instruments used in emergency departments in developed countries at present and owned by a few hospitals in China. The main drawback of the C-clamp is the relative complexity of the operation, which requires the cooperation of several persons. The needle insertion point is relatively difficult to locate, and when the position is not good and needs to be adjusted, the needle insertion point needs to be located from the beginning. Therefore, there is a need for an external pelvic fixation guide that can assist in precise intraoperative positioning.
Disclosure of Invention
The invention aims to overcome the existing defects and provide an external fixing guide plate for accurately positioning pelvic fracture surgery and a using method thereof aiming at the problems of infirm fixation and incapability of accurate positioning of the existing pelvic fixing support. In order to solve the problems, the invention adopts the following technical scheme:
the utility model provides an external fixation baffle of accurate positioning pelvis fracture operation, includes the support and installs the equipment on the support, equipment includes perforating device and positioner, the mid portion is the isosceles trapezoid structure that stands upside down, perforating device sets up respectively the tip of 2 flanks, positioner is cylindrical cylinder structure, positioner sets up respectively 4 summits departments of mid portion, 2 positioner of upside are used for fixing a position patient pelvis ilium wing department, 2 positioner of downside are used for fixing a position pubic tubercle department.
Furthermore, the perforating device comprises a first working channel sleeve, a first soft tissue ejector and a first Kirschner wire sleeve, the first working channel sleeve is arranged at the top end of the perforating device and connected with the first soft tissue ejector, and the other end of the first soft tissue ejector is connected with the first Kirschner wire sleeve.
Furthermore, an auxiliary positioning plate is arranged in the center of the bottom edge of the middle part and used for aligning the center of pubic symphysis.
The invention has the technical effects that:
the four positioning devices are arranged on the support to realize the positioning of the fractured pelvis, the pelvis supports with different sizes are manufactured for different people, and the angle of the perforating device is adjusted through simulation experiment operation before the pelvis supports are used, so that the accurate positioning in the operation process is realized, the pain of a patient is reduced, and the success probability of the operation is increased.
