Abstract

A force line positioner for the high tibial osteotomy comprises a force line measuring piece and a fixing assembly. The force line measuring piece is a length extending piece with the consistent extending direction as the lower limbs of a human body. The two ends are aligned to the central point of the human body caput femoris and the central point of the ankle for measuring a lower limb force line; the fixing assembly is used for installing the force line measuring piece and connected with the human body, and at least one end of the force line measuring piece is movably connected with the fixing assembly so that the end of the force line measuring piece can be adjusted inside the horizontal plane perpendicular to the length direction of the force line measuring piece. The problems that due to the fact that according to the existing high tibial osteotomy, a surgeon needs to hold the force line measuring piece by hand to perform the positioning work, the accuracy of the high tibial osteotomy is affected, the radiated dosage of the surgeon is increased, and the body health of the surgeon is affected are solved.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a line of force locator for high tibial osteotomy. Background technique

[0002] For young patients with symptoms of degenerative arthritis and varus knee, as the degree of cartilage wear in the inner joint of the knee increases, it becomes a bent leg, which induces pain, and when standing and walking, the weight is concentrated on one side, making the arthritis worse and the pain more severe Heavy. For the surgery of this medial deformed leg, a high tibial osteotomy near the knee of the medial high tibia is used.

[0003] High tibial osteotomy is a method of performing osteotomy on the high part of the tibia so that the body weight concentrated on the inner side of the knee joint is distributed more to the outer side to reduce pain. Such as Figure 8 Shown is an X-ray photo of a human body requiring high tibial osteotomy. The line from the center of the femoral head to...
