Intraoperative reducing and positioning device for complicated fractures around knee joints

Abstract

The invention relates to an intraoperative reducing and positioning device for complicated fractures around knee joints and belongs to the technical field of orthopedic medical devices. The device is used for reducing fractures during operation, recovering lower limb force lines and implementing effective maintenance. The technical scheme includes that the device comprises sliding rails, angle positioning rods, rotation positioning rods, pin seats and foot boots, the sliding rails are parellelly fixed on an operating table, two angle positioning rods per group are connected to the two sliding rails respectively, the lower ends of the angle positioning rods are connected with the sliding rails in a sliding mode, the 2-4 rotation positioning rods are connected with the sliding rail on one side, the upper portions of the rotation positioning rods are bent into arc shapes, the pin seats for installing kirschner pins / sternmann pins are arranged at the front ends of the rotation positioning rods, the lower ends of the rotation positioning rods are connected with the sliding rails in a sliding mode, and the foot boots are located at one ends of the sliding rails. The intraoperative reducing and positioning device is simple in structure, convenient to use, and capable of rapidly and accurately reducing the fractures, recovering and effectively maintaining the lower limb force lines, greatly solving the problem that the lower limb force lines are prone to be poor after fracture fixation in current operations on complicated fractures around knee joints, and greatly improving qualities of operations.

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.
