Abstract

A two-dimensional survey meter for condyles on inner and outer sides of thighbone comprises a rectangular frame, wherein the rectangular frame is composed of a lower side cross rod, a left side vertical rod, an upper side cross rod and a right side vertical rod, wherein the rectangular frame is placed in front of the surface of a tibiofemoral joint, the upper side cross rod and the right side vertical rod are adjusted so as to be respectively and closely close to the front surface and a side surface of the tibiofemoral joint, namely the widths and the depths of the condyles on inner and outer sides of thighbone, and angles formed by the vertical planes of the condyles on inner and outer sides and a horizontal plane can be metered. The two-dimensional survey meter provided by the invention adopts a plurality of metering rulers to form a two-dimensional frame, protractors are respectively arranged in two directions, the sizes and the angles of the condyles on inner and outer sides at the rear end of the thighbone can be metered conveniently, necessary positioning work before full knee joint replacement can be provided, and risk in operations for patients can be lowered.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a preoperative positioning device for medical orthopedic total knee arthroplasty (or total knee replacement), in particular to a two-dimensional measuring device for the medial and lateral femoral condyles. Background technique: [0002] For severe knee joint disease, such as severe knee osteoarthritis, advanced rheumatoid knee disease, knee joint dysfunction after severe joint trauma, knee osteochondral necrosis involving the articular surface, tumors, etc. Traditional drugs and physical therapy are often ineffective. It is necessary to reconstruct the function of the knee joint to improve the quality of life of the patient. In addition to superb orthopedic surgery skills, advanced prosthetic materials, scientific design and supporting equipment are also required. [0003] The front part of the distal femur is called the trochlear, and there is a notch in the front and rear direction in the...
