External fixation bracket with pressurized thread for orthopedics

Abstract

The invention discloses an external fixation bracket with a pressurized thread for orthopedics, relating to an orthopaedic medical apparatus for external fixation of trauma at the parts of limbs, joints and the like. The bracket comprises a connecting bar, a pressurized fixation needle and a fixation block assembly, wherein the fixation block assembly comprises an external hexagonal connecting nut, a spiral spring, a connecting rod, an internal pressurized fixation needle fixation block, an external pressurized fixation needle fixation block, a connecting bar fixation sleeve and a circular spring piece; the connecting rod is provided with a connecting rod body, two ends of the connecting rod body are respectively provided with a threaded rod, the middle of the connecting rod body is provided with a circular arc groove I for clamping the connecting bar, one side of the circular arc groove I is provided with an installation step, and the end part of the installation step is provided with a circular groove I for containing the circular spring piece and is also provided with multiple jugged bulges matched with the internal pressurized fixation needle fixation block; and the connectingbar fixation sleeve is provided with a stepped hole, and the circumferential surface of the connecting bar fixation sleeve is provided with a circular arc groove II matched with the circular arc groove I in the middle of the connecting rod boy and used for clamping the connecting bar.

Description

technical field [0001] The orthopedic external fixation bracket with pressurized thread of the present invention relates to an orthopedic external fixation trauma medical device used for limbs, joints and other parts. Background technique [0002] Now, with the frequent occurrence of fractures in the elderly, if surgery is used, it needs to be performed under epidural or spinal anesthesia (semi-body anesthesia). Due to the large surgical incision, the muscles are stripped and cut off on the bone surface, bleeding is much, and the risk is high. Surgery A blood transfusion is required at the same time, and a second operation is required to remove the implant. Traction and plaster external fixation are also often used. Although there is no need to cut skin and flesh tissue, the bleeding is less, but the patient needs to stay in bed for a long time after the operation. Ordinary external fixation brackets, this kind of technology all use Steiner wires. However, the binding forc...

AI Technical Summary

Problems solved by technology

However, the binding force for the fracture is poor, and the fracture site cannot be effectively stabilized. Because the needle position is scattered and far away from the fracture end, the muscle movement is obviously restricted, which reduces the patient's self-care activities and joint activities, resulting in joint stiffness.
