Abstract

The invention relates to a gap detector used in knee joint replacement surgery, the gap detector comprises a straightening gap detection box and a buckling gap detection box, the straightening gap detection box comprises a first box bottom plate and a first box top plate capable of moving up and down relative to the first box bottom plate, the detector further comprises a first driving shaft, and the axis of the first driving shaft extends in the left-right direction; the flexion gap detection box comprises a second box bottom plate and a second box top plate capable of moving up and down relative to the second box bottom plate, the upper end face of the second box top plate is an arc-shaped concave face matched with a flexion femur, the detector further comprises a second driving shaft with the axis extending in the left-right direction, and the first driving shaft is of a hollow structure; and a movable gap is formed between the inner hole wall of the first driving shaft and the outer peripheral surface of the second driving shaft in the vertical direction. The technical problems that in the prior art, when a detector fills a straightening gap and a buckling gap, the number of filling plates can be increased only by expanding a thighbone tibia by a large size, labor intensity is large, and ligaments are prone to being damaged are solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a gap detector used in knee joint replacement surgery used in knee joint replacement surgery. Background technique [0002] The knee joint is the main weight-bearing joint of the human body. For the elderly, when the knee joint is damaged, knee joint replacement is the main means to improve the quality of knee joint arthritis. Knee joint replacement surgery is to install a femoral prosthesis at the end of the femur. A tibial prosthesis is installed at the end, and the femoral prosthesis and the tibial prosthesis together form an artificial joint, allowing the patient to stand again and walk normally. [0003] During the installation of the femoral prosthesis and the tibial prosthesis, due to the necrosis or wear of the femur and tibia, and in order to match the installation of the femoral prosthesis and the tibial prosthesis, the femur and tibia need to be osteotomized. One pl...
