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

Embodiment 1

[0039] Such as figure 1 , figure 2 with image 3 The shown closed osteotomy guide includes a base, a first osteotomy guide block and a second osteotomy guide block installed on the base, the first osteotomy guide block and the second osteotomy guide block The osteotomy guide block can slide on the base along an arc track, and a plurality of first positioning sleeves 4 for passing Kirschner wires 15 are installed on the first osteotomy guide block, so A plurality of second positioning sleeves 5 for piercing Kirschner wires 15 are installed on the second osteotomy guide block, the axes of the plurality of first positioning sleeves 4 are all located in the first vertical plane, and the axes of the plurality of first positioning sleeves 4 are all located in the first vertical plane. The axes of the two positioning sleeves 5 are all located in the second vertical plane, the intersection of the first vertical plane and the second vertical plane forms the vertical axis of the oste...

Embodiment 2

[0052] Such as Figure 4 , Figure 5 with Image 6 As shown, in this embodiment, the difference from Embodiment 1 is that the base has an arc-shaped surface 8-1, and the base is vertically provided with a concentric arrangement with the arc-shaped surface 8-1. Arc-shaped through groove 8-2, the first osteotomy guide block and the second osteotomy guide block both include a guide block main body 9-1 and an arc-shaped guide set on the bottom surface of the guide block main body 9-1 plate 9-2, the arc guide plate 9-2 can slide along the length direction of the arc slot 8-1.

[0053] In this embodiment, there is an arc-shaped surface 8-1 on the base, and an arc-shaped through groove 8-2 is provided vertically on the base, and the arc-shaped through groove 8-2 and the arc-shaped surface 8-1 Arranged concentrically, the first osteotomy guide block and the second osteotomy guide block both include a guide block main body 9-1 and an arc-shaped guide plate 9-2. During actual install...

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...
