Abstract

The invention discloses a bone traction device, and relates to the technical field of medical instruments. The bone traction device comprises a base, a support component for supporting a limb of a patient and a traction component for pulling the limb. The traction component comprises a traction frame mounted on the base and a traction rope respectively connected to the traction frame and the limb,and the traction rope is provided with an adjustment assembly for adjusting the length of the traction rope. The traction frame comprises a lifting rod hinged on the base and a traction rod connectedto the lifting rod through a locking mechanism. The locking mechanism includes a gear I disposed on the side end portion of the lifting rod, a gear II disposed on the side end portion of the tractionrod and matched with the gear I and a control component for controlling whether the gear I and the gear II are meshed. The gear I and the gear II include a plurality of racks arranged in a circular shape uniformly, and the rack mounting direction is consistent with the circular radial direction. The bone traction device has the advantages of being simple in structure, convenient to operate, efficient and practical, good in treatment rehabilitation efficacy and capable of adjusting the direction, the angle and the size of the therapeutic traction force.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bone traction device. Background technique [0002] The existing Brown-type bone traction frame is composed of a main body stainless steel or metal iron support frame, gauze bandage or cloth belt, bedside fixing device, pulley, traction bow, traction rope, weight hook, weight, etc. It is clinically used to treat fractures. It is a necessary treatment device for the restoration of dislocation, maintaining good alignment and stability after restoration, preventing and correcting joint deformity, relieving muscle spasm and pain, and preoperative traction treatment of fractures or final treatment of certain types of fractures. . [0003] The main structure of the Brown-type bone traction frame is welded by iron or stainless steel. This structure has the advantages of firm structure, but it lacks the flexibility of length and fixed angle. In this way, it is difficult to...
