Closed osteotomy guider

Abstract

The invention discloses a closed osteotomy guider. The osteotomy guider comprises a base, a first osteotomy guide block and a second osteotomy guide block, both the first osteotomy guide block and thesecond osteotomy guide block can slide on the base along an arc track, a plurality of first positioning sleeves used for allowing kirschner wires to penetrate through are installed on the first osteotomy guide block, a plurality of second positioning sleeves used for allowing the kirschner wires to penetrate through are installed on the second osteotomy guide block, the axes of the first positioning sleeves are all located in a first vertical plane, and the axes of the second positioning sleeves are all located in a second vertical plane. With the osteotomy guider, a plurality of kirschner wires can be quickly and accurately drilled into an ideal position in a bone, the flatness of a first osteotomy plane and a second osteotomy plane can be guaranteed, so that the integrity of the two side faces of a wedge-shaped bone block cut from the bone is guaranteed, the first osteotomy plane and the second osteotomy plane can be tightly attached to each other conveniently, and the phenomena ofjoint stiffness and fracture broken end non-healing can be avoided.

Description

technical field [0001] The invention belongs to the technical field of orthopedic surgery operating tools, and in particular relates to a closed osteotomy guide. Background technique [0002] Osteotomy orthopedics is a commonly used method for the treatment of limb deformities and arthritis, especially around the knee joint. Incomplete osteotomy has the advantages of firm fixation, early mobilization, and quick healing of the broken ends. Incomplete osteotomy can be divided into two types: closed osteotomy and distraction osteotomy. In the closed osteotomy operation, not only the integrity of the osteotomy hinge needs to be considered, but also the thickness of the bone block obtained after the osteotomy must be accurate, and the two osteotomy planes after closure should fit together as completely as possible. What kind of osteotomy is perfect, and accurate preoperative planning can be made, but in closed osteotomy, it is difficult for doctors to perform accurate closed ost...

AI Technical Summary

Problems solved by technology

In the closed osteotomy operation, not only the integrity of the osteotomy hinge needs to be considered, but also the thickness of the bone block obtained after the osteotomy must be accurate, and the two osteotomy planes after closure should fit together as completely as possible. What kind of osteotomy is perfect, and accurate preoperative planning can be made, but in closed osteotomy, it is difficult for doctors to perform accurate closed osteotomy according to the preoperative plan, and X-ray perspective is needed With the assistance of the machine, the doctor can only place the Kirschner wire in a relatively satisfactory osteotomy position through repeated attempts. Not only does the operation take a long time, but also the doctor and the patient will suffer a lot of X-ray radiation damage, and the final Kirschner wire Whether the placement position is ideal can not be verified by measurement or objective data. It can only be judged by the doctor's experience and naked eye observation, which will affect the surgical effect. Therefore, a closed osteotomy guide that is easy to operate and can guide accurately should be provided
