Embodiment

[0045] This embodiment provides a precise osteotomy guide, such as Figure 1-2 As shown, it comprises: a frame 1 with a main pole 10, a first pole 11 slidably sleeved on the main pole 10, and a second pole 12 fixedly connected to one end of the main pole 10, so The first support rod 11 is parallel to the second support rod 12 and forms a U-shaped structure together with the main rod 10; the positioning structure is arranged on the first support rod 11 and is suitable for positioning on the fibula. Side; the first position determining member 3, installed on the first strut 11, used to determine the distance between the center of the positioning structure and the tibial plateau; the guide structure, arranged on the second strut 12 , The nailing direction for guiding the Kirschner wire is toward the center of the positioning structure; the second position determining member is installed on the second supporting rod 12 and is used for determining the guiding structure for guiding th...

Abstract

The invention provides a precise osteotomy guider. The precise osteotomy guider comprises a frame, a positioning structure, a first position determining part, a guide structure and a second position determining part, wherein the frame is provided with a main rod, a first supporting rod capable of sleeving the main rod in a sliding manner and a second supporting rod fixedly connected with one end of the main rod, and the first supporting rod and the second supporting rod are parallel and form a U-shaped structure together with the main rod; the positioning structure is arranged on the first supporting rod and is suitable for being positioned on one side of the fibula; the first position determining part is mounted on the first supporting rod and used for determining the distance between thecenter of the positioning structure and the tibial plateau; the guide structure is arranged on the second support rod and used for guiding the nailing direction of a Kirschner wire to face the centerof the positioning structure; and the second position determining part is mounted on the second supporting rod and used for determining the distance between the center of a guide hole, used for guiding the Kirschner wire, of the guide structure and the tibial plateau. According to the precise osteotomy guider, the osteotomy positions of the outer side and the inner side of the tibial plateau canbe precisely given, it can be guaranteed that the wire inserting direction of the Kirschner wire is accurate, deflection is reduced or avoided, and the osteotomy efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of auxiliary tools for orthopedic osteotomy, in particular to a precise osteotomy guide. Background technique [0002] Patients with knee varus deformity, especially young patients with genus varus with abnormal development of the proximal tibia, need to undergo high-position proximal tibial osteotomy for orthopedic knee joint pain. The treatment mechanism of high proximal tibial osteotomy orthopedic surgery is to use proximal tibial osteotomy to transfer the load-bearing line from the inflammation and wear of the medial compartment of the knee joint to the relatively normal lateral compartment to relieve the symptoms of arthritis the goal of. [0003] Specifically, the knee joint with normal force usually bears more weight on the inside and less weight on the outside. If there is a certain degree of varus deformity in the tibia, it will significantly increase the pressure on the cartilage of the medial compartme...
