Measuring device for hip replacement surgery

Abstract

The invention provides a measuring device for hip replacement surgery, and relates to the technical field of medical measuring instruments. A semicircular groove is formed in the middle of the top of the base, a limiting groove is formed in the front end of the semicircular groove of the base, the rear end of the limiting groove of the base is located in the circle center of the semicircular groove of the base, and an attaching block slides in the limiting groove of the base. The mesh lines on the side surface of the fitting block are in one-to-one correspondence with the scale strips below the front end of the fitting block and at the front end of the bottom of the fitting block. According to the distance of the attaching block, the rotating block is determined and rotated, the position of the measuring rod on the scale value of the measuring frame is correspondingly observed, and when the measuring rod is determined to rotate to a proper relative position, the measuring rod is adjusted to enable the front end position of the measuring rod to be attached to the position of the arc-shaped plate of the limiting frame, so that the section distance length of the arc-shaped height of the hip bone head of the patient can be determined. The problem that the arc angle of the hip bone head position of a patient cannot be relatively measured is solved.

Description

technical field [0001] The invention belongs to the technical field of medical measuring instruments, and more specifically relates to a measuring device for hip joint replacement surgery. Background technique [0002] Hip replacement is to fix the artificial prosthesis, including the femoral part and the acetabular part, on the normal bone with bone cement and screws to replace the diseased joint and reconstruct the normal function of the patient's hip joint. It is a relatively mature and reliable procedure. treatment means. [0003] Similar to the current measurement of hip replacement surgery, there are still the following deficiencies: one is that when the patient's necrotic hip bone is replaced, the height of the human body is different, so the size of the corresponding replacement prosthesis is different, and it takes a lot of time to measure the size of the hip bone On the other hand, according to the skeletal structure of different groups of people, the structure of...

[0003] Similar to the current measurement of hip replacement surgery, there are still the following deficiencies: one is that when replacing a patient’s necrotic hip bone, the height of the human body makes the size of the corresponding replacement prosthesis different, and it takes a lot of time to measure the size of the hip bone. On the other hand, according to the skeletal structure of different groups of people, the structure of the hip bone position may not be relatively well-proportioned, and the relative measurement of the arc angle of the patient's hip bone position cannot be carried out. There is a certain deviation
