Embodiment Construction

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0037] Such as Figure 1 to Figure 5 As shown, the embodiment of the present invention provides a femur measurement device, including a body 6, a slide bar 5, a probe 2 and an external rotation plate 10, wherein the bottom of the body 6 is provided with a positioning plate protruding backward, The positioning plate is in the shape of a foot, and is arranged on both sides of the body 6, and is used to support the posterior femoral condyle. The measurement of the parameters of the femoral condyle and the positioning of the internal and external rotation angle are performed on the basis of the posterior femoral condyle. The top is provided with a jack extending downwards, and the front is provided with an observation hole communicating with the jack, and th...

Abstract

The invention provides a femur measuring device. The femur measuring device comprises a body; a positioning plate is arranged at the bottom of the body; a sliding rod capable of moving up and down androtating left and right along the body is inserted into the top of the body; a detection needle capable of moving along the top of the sliding rod is inserted into the top of the sliding rod; a specification scale line I is arranged on the detection needle; a scale line II is arranged on the front side of the body; an external rotating plate is arranged on the rear side of the body; a knob capable of driving the external rotating plate to rotate is arranged on the front side of the body; and the front side of the body is provided with an R scale and an L scale which are arranged around the knob. The femoral measurement device integrates femoral parameter measurement of a left knee joint and a right knee joint and the internal-rotation and external-rotation positioning function into a whole, and continuous internal-rotation and external-rotation angles can be selected for adjustment, so that the femoral measurement device is greatly convenient for a doctor to measure the femoral parameters, select types of femoral prosthesis and position the internal-rotation and external-rotation angles of femoral osteotomy, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a femur measuring device. Background technique [0002] The knee joint is the largest and most complex joint in the human body. Knee replacement surgery is to replace all or part of the patient's damaged natural knee joint with a knee prosthesis. Osteotomy for femoral prosthesis installation. Generally, it is first necessary to perform an osteotomy on the distal end of the femur, and then measure the parameters of the femoral condyle with the osteotomy surface as a reference plane, and determine the position of the osteotomy module in the next step. The measurement of the parameters of the femoral condyle is mainly to determine the distance between the posterior femoral condyle and the anterior surface of the femur, so as to select the appropriate size of the femoral prosthesis. The determination of the position of the osteotomy module generally takes the posterior ...
