Traumatic orthopedics department reduction fixing instrument with accurate positioning

Abstract

The invention discloses a traumatic orthopedics department reduction fixing instrument with accurate positioning, and belongs to the technical field of reduction fixing instruments. The instrument comprises a control box, an air source, an air pump and a foot stool, two sides of the foot stool are welded with one ports of two mutually symmetrical shank rods, a vertical pedal is also fixed on the foot stool, and an adhesive tape is bound on the pedal; and the other ports of the shank rods are fixed with one end of a biaxial joint, and a concave arc-shaped plate is fixed between the shank rods on one side of the biaxial joint. According to the trauma orthopedics department reduction fixing instrument with the accurate positioning, an ellipsoidal pointed end part filled with an expanded air bag is matched with a left arc plate and a right arc plate to form an ellipse, the air bag expands to abut against the upper side and the lower side of a thigh, a shank is supported on the arc plate, a foot sole abuts against the pedal, a instep is bound through the adhesive tape, accurate fixing of a leg position is completed, a motor drives a gear to rotate, a thigh rod rotates along a tooth groove, an angle of a fixing mechanism is bent, an angle of the thigh and the shank can be changed, and long-term limitation on leg movement is avoided.

Description

technical field [0001] The invention relates to the technical field of reduction and fixation instruments, in particular to a trauma orthopedic reduction and fixation instrument for accurate positioning. Background technique [0002] When the bones of the legs and arms are misaligned or fractured, in order to avoid secondary injuries and affect the restoration and growth of the bones, it is necessary to borrow a reset fixation frame to reset and fix the injured position to help it grow better. ; [0003] When a leg or arm is fractured, because the fractured part may be different in thickness, in the prior art, the existing combined reduction and fixation frame for orthopedics cannot be applied to fracture parts of different sizes, and cannot be used to treat the fractured part of the leg or arm well. Protection, during the recovery process of the patient, even if the orthopedic combined reduction and fixation frame is worn, secondary injuries will be caused. [0004] In or...

AI Technical Summary

Problems solved by technology

[0005] During bed rest, it is necessary to elevate the injured leg through gauze and lanyards and other medical items to promote blood circulation and prevent edema. Elevation can easily cause pain in the hanging part of the patient's legs. If the body is heavy, it is easy to produce bruises. Long-term suspension gauze and lanyards will loosen, reducing the height of the leg lift. After adjusting the length of the gauze and the lanyard, and raising the legs, it is difficult to maintain the same posture all the time. Long-term restriction of leg activities can easily cause costly atrophy of the leg muscles, joint stiffness and even spasm. This is the deficiency of the existing technology place
