Multifunctional traction and fixing device for bone setting

Abstract

The invention relates to the technical field of medical instruments, and provides a multifunctional traction and fixing device for bone setting combined by various parts.Two traction splints (1) are used as bases, traction nails (2) are arranged at front ends of the traction splints (1), positioning and pressurizing screws (3F) are arranged at middle portions of the traction splints (1),a traction handle screw (3) is arranged at rear ends of the traction splints, and a plurality of auxiliary fixing needle holders and auxiliary fixing needles (6) are arranged on the traction splints (1); nail heads of the two traction nails (2) oppositely abut against a lower end of a fracture to confirm a fixing position, and the rear ends of the two traction splints (1) are pulled along a thigh direction by means of traction; and if multiple fractures need auxiliary fixation, matching auxiliary fixing needle holders are selected according to different fracture displacements, and the auxiliary fixing needles (6) are installed to abut against fractured bones and fix the fractured bones. Minimally invasive treatment integrating traction and fixation is achieved, and most fractures do not need a surgical internal fixation operation; and the multifunctional traction and fixing device is convenient to install and is stable and has an obvious effect, and a patient does not need multiple operations.

Description

technical field [0001] The patent of the present invention relates to a multi-functional traction osteosynthesis fixation device for medical operations. The traction osteosynthesis fixation device is mainly used for the new technology of traction fixation and minimally invasive treatment of human limb fractures or comminuted fractures. Background technique [0002] At present, in the medical field, there are many treatment methods for human limb fractures. Traditional Chinese medicine conservative treatment: 1. external fixation with plaster; 2. external fixation with splint; these treatment methods can only be used for minor injuries of bone cracking Accurate positioning of completely displaced fractures; Western medicine: There is traditional traction therapy, where the traction nail is driven into the human body to penetrate the bone. Advantages: small scars; Disadvantages: 1. The traditional traction nail is designed for one piece, and it must be penetrated into the human...

[0002] At present, in the medical field, there are many treatment methods for human limb fractures. Traditional Chinese medicine conservative treatment: 1. external fixation with plaster; 2. external fixation with splint; these treatment methods can only be used for minor injuries of bone cracking Accurate positioning of completely displaced fractures; Western medicine: There is traditional traction therapy, where the traction nail is driven into the human body to penetrate the bone. Advantages: small scars; Disadvantages: 1. The traditional traction nail is designed for one piece, and it must be penetrated into the human body The bone vibrates greatly, which affects the complete displacement of the cracked bone and causes secondary damage; 2. Traditional traction nails can only penetrate a single bone when penetrating the human body, but the lower limbs of the human body are not suitable for two bones, so the doctor chooses to drive the traction nail into The calcaneus, because the calcaneus and the bones of the lower leg are not on the same vertical line, the traction effect cannot be guaranteed. Therefore, the western doctors in the hospital now choose to use steel plates for internal fixation in surgery; the internal fixation with steel plates looks OK on the surface, but it is not scientific to analyze But it hurts a lot. 1. When it comes to surgery, people talk about it, causing psychological fear. 2. Waist anesthesia is also very uncomfortable, and some people have bruises due to improper anesthesia. The sequelae left behind; 3. The operation is fixed with a steel plate. The shape angle of the steel plate does not completely match the natural curve of the human bone. In addition, when the blood is blurred, the three parties cannot see the bone setting in one small opening. Abnormal alignment failed to meet the requirements of anatomical alignment, which affected the slow growth of bone, resulting in secondary surgery, and some bone grafting (removing the top and filling the bottom) and other phenomena, and even caused lifelong disability of the patient due to serious alignment errors. ;4. Even if the operation goes well one year later, the secondary injury caused by the internal fixation operation will still be removed. Internal fixation is often difficult to find because the incision edge is blurred, which increases the damage caused by the surgical knife injury to the human body.
