Fracture area temporary fixation system and fixation method thereof

Abstract

The invention discloses a fracture area temporary fixation system and a fixation method thereof. The fracture area temporary fixation system comprises a plurality of negative pressure suction nozzles, a fixation plate and negative pressure control connectors, wherein the negative pressure suction nozzles are used for sucking broken bone blocks in a fracture area, the fixation plate is detachably and fixedly connected with the negative pressure suction nozzles, and the negative pressure suction nozzles are communicated with a negative pressure source through the negative pressure control connectors to realize negative pressure control. The broken bone blocks among broken bones are sucked by the negative pressure suction nozzles and uniformly temporarily fixed by the fixation plate until final fixation is finished, temporary fixation is removed by releasing negative pressure, the problem of re-displacement of the broken bone blocks after loosening of a fixer in the conventional surgical process is solved, a plurality of broken bone blocks can be temporarily fixed simultaneously, all the broken bone blocks are fixed in place once, the operation space of an implanted steel plate in a fracture surgery is effectively ensured, manpower in the surgical process is decreased, surgical reduction effects are improved after the steel plate is implanted, and the fixation system is ingenious in design, simple in structure and convenient to operate and can be widely popularized and applied in the clinical fracture surgery.

Description

technical field [0001] The invention belongs to medical equipment, and in particular relates to a temporary fixation system for a fracture area and a fixation method thereof. Background technique [0002] In orthopedic surgery for extremity fractures (especially for limb fractures), a large part of them are comminuted fractures, such as comminuted ulnar and radial fractures, comminuted humeral fractures, comminuted tibia and fibula fractures, and comminuted femur fractures. During the operation of this kind of comminuted fracture, it is necessary to temporarily reset the fracture fragments [0003] At present, orthopedic instruments such as bone-holding forceps, rat-tooth forceps, and three-claw forceps are commonly used in orthopedic surgery to temporarily hold the broken bone for reduction. The bone fragments are fixed together. However, due to the use of irregular clamping instruments to quickly reset the broken bone, the operating space for implanting the steel plate h...

AI Technical Summary

Problems solved by technology

However, due to the use of irregular clamping instruments to quickly reset the broken bone, the operating space for implanting the steel plate has been greatly affected. Usually, the above clamping instruments need to be removed to implant in the proper position of the fractured bone. However, in fact, most of the bone fragments have muscle adhesion and self-gravity, and have different shapes. Once the fixation of the clamping and reset device is removed, the fragments will quickly recover under the action of gravity and muscle traction. The displacement will seriously affect the reset effect of the broken bone. At this time, it is necessary to reset the broken bone again through the clamping instrument, which will greatly increase the operation time during the operation, which will lead to prolonged operation time, increased patient bleeding, and increased risk. Large, increased patient costs, increased chances of infection, unsatisfactory reduction effect, etc.
