Embodiment Construction

[0037] The following is attached Figure 1-5 The application is described in further detail.

[0038] The embodiment of the present application discloses an adjustable tibial osteotomy guide. refer to figure 1 and figure 2 , the adjustable tibial osteotomy guide includes an osteotomy guide 1, a driving component 2, a reclining adjustment component 3, and a fixing component 4; the osteotomy guide 1 is used for positioning the osteotomy site of the unicondylar tibia of the knee joint, The driving assembly 2 is used to drive the osteotomy guide 1 to move horizontally and vertically, so that the medical personnel in the knee joint unicondylar tibial replacement surgery can quickly adjust the position of the tibial osteotomy, and the backward tilt adjustment assembly 3 can be adjusted according to the needs of different patients. Adjustment of the tibial angle realizes the adjustment of the reclining angle of the unicondylar tibial osteotomy of the knee joint to adapt to the ti...

Abstract

The invention relates to a tibia osteotomy guider, which belongs to the technical field of orthopedic medical instruments and comprises an osteotomy guide part, a driving component for driving the osteotomy guide part to move and a retroversion adjusting component for adjusting a tibia retroversion angle. The osteotomy guiding piece comprises an arc-shaped plate and a fixing plate, and the arc-shaped plate and the fixing plate are perpendicularly arranged and fixedly connected. The arc-shaped plate is provided with a transverse osteotomy guide groove extending in the length direction of the arc-shaped plate, and the transverse osteotomy guide groove penetrates through the two sides of the arc-shaped plate. A longitudinal osteotomy guide groove is formed in the fixing plate and penetrates through the two sides of the fixing plate. The tibia osteotomy guider has the effects of quickly adjusting the osteotomy position and accurately adjusting the retroverted angle during knee joint unicompartmental knee arthroplasty and facilitating a doctor to quickly and accurately cut off a tibia lesion part, the success rate of an operation is increased, the pain of a patient is reduced, and the satisfaction degree of the patient is guaranteed.

Description

technical field [0001] The present application relates to the technical field of orthopedic medical devices, in particular to an adjustable tibial osteotomy guide. Background technique [0002] Knee osteoarthritis is a common disease. Patients with knee osteoarthritis are often accompanied by lower limb changes and varus deformities, which seriously endanger people's quality of life. In order to improve knee osteoarthritis, the knee joint is usually treated Proximal tibial osteotomy is the most important step in unicompartmental knee arthroplasty. [0003] The tibial osteotomy guide is commonly used in unicompartmental knee replacement surgery. The tibial osteotomy guide is used to determine the tibial osteotomy position and adjust the posterior inclination angle of the tibial osteotomy in joint replacement surgery. The existing tibial osteotomy guide is mainly through The position of the tibial osteotomy is determined by the extramedullary line of force, and the position o...
