Intraoperative reducing and positioning device for complicated fractures around knee joints

Abstract

The intraoperative reduction and positioning device for complex fractures around the knee joint belongs to the technical field of orthopedic medical devices, and is used for fracture reduction, recovery of lower limbs and effective maintenance during surgery. The technical solution is: it includes slide rails, angle positioning Rods, rotating positioning rods, needle holders, foot boots, and two slide rails are fixed on the operating table in parallel. Each group of two angle positioning rods is respectively connected to the two slide rails, and their lower ends are slidable with the slide rails. There are 2-4 rotating positioning rods, which are connected to the slide rail on one side. Their upper parts are curved in an arc shape, and there are needle holders for installing Kirschner wires / Schner wires at the front end, and the lower end and the slide rail can be connected. Sliding connection, the foot boot is located at one end of the slide rail. The present invention is simple in structure and easy to use, can quickly and accurately reset fractures, restore lower limbs and maintain them effectively. the quality of.

Description

technical field [0001] The invention relates to a reset and positioning device for performing fracture reduction, restoring lower limb line of force and effectively maintaining during complex fracture operations around the knee joint, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Fractures around the knee mainly include distal femur fractures and proximal tibial fractures. The diagnosis and treatment of complex fractures around the knee joint, such as multi-segment fractures of the distal femur and proximal tibia and comminuted fractures, are still the focus and difficulty faced by orthopedic surgeons. Surgical treatment is the treatment of choice for complex fractures around the knee. Due to the lack of effective reference objects, anatomical reduction of complex fractures around the knee has high requirements for the surgeon, and for comminuted fractures, fracture reduction is often unsatisfactory. In addition, surgical t...

AI Technical Summary

Problems solved by technology

For patients with floating knee injuries, two assistants are required to hold the bone and tibia respectively during the operation, and the reduction of the fracture and the alignment of the lower limbs cannot be maintained stably during the operation, which may affect the therapeutic effect; in addition, the two assistants may occupy the space of the surgeon and affect the surgeon Surgical operation

At present, there is no clinically available device that can assist fracture reduction, restore lower limb alignment and effectively maintain it. It is very necessary to design an intraoperative reduction and positioning device for complex fractures around the knee joint.
