Embodiment Construction

[0012] Such as figure 1 , figure 2 , image 3 The spinal reset device shown includes a positioning seat 2 and a push rod 4. Both sides of the positioning seat 2 are symmetrically provided with connecting rods 1. One end of the two connecting rods 1 is fixedly connected to the positioning seat 2. The connecting rod 1 is an arc-shaped rod. The two arc-shaped connecting rods 1 are on the same arc surface; the arc of the arc-shaped rod is the same as the physiological curvature of the spine, and the connection with the spine is smoother and more stable. The positioning seat 2 is in the shape of a cylindrical sleeve, and the middle part of the positioning seat 2 is provided with a push screw hole 6, and the push rod 4 is provided with a push screw thread 3 matched with the push screw hole 6. image 3 It can be seen that the push thread 3 is located at the front of the push rod, and the push rod is connected with the positioning seat through the push thread and the push thread ho...

Abstract

The invention provides a vertebral column reduction device and relates to the technical field of medical equipment for orthopedic surgeries. The vertebral column reduction device comprises a positioning seat and a push rod. Connecting rods are symmetrically arranged on the two sides of the positioning seat, one end of each of the two connecting rods is fixedly connected with the positioning seat, the middle of the positioning seat is provided with a pushing threaded hole, the push rod is provided with a push thread matched with the pushing threaded hole, and the push rod is matched and connected with the positioning seat through the push thread and the pushing threaded hole. The vertebral column reduction device has the advantages of being simple in structure, simple and convenient to operate, high in reduction controllability, good in effect and excellent in treatment effect and causing no secondary damage to lesion joints.

Description

technical field [0001] The invention relates to the technical field of medical instruments for orthopedic surgery, and in detail is a spinal reset device with simple structure, convenient operation, good reset effect and good operation effect. Background technique [0002] We know that when the spine is dislocated due to disease, external force, etc., it is necessary to use orthopedic rods for orthopedic reduction. During the operation, the dislocated vertebrae need to be reset first, and then fixed with orthopedic rods. At present, in the operation of resetting the dislocated vertebral segments, doctors use common surgical forceps, surgical scissors, jacking bars and other auxiliary devices that can push the diseased joints to perform the reset operation of the diseased joints. This kind of reset operation has the following disadvantages: 1. The operation is difficult and requires experienced doctors to operate; 2. The reset position of the diseased joint is uncontrollable...
