Abstract

The invention discloses a measurer for measuring the femoral offset in an orthopedic operation. The measurer comprises a base, wherein a depth measuring device which is used for measuring the depth of a corpus femoris by inserting into the corpus femoris is arranged on the lower part of the base; a diameter measuring device which is used for measuring the width of a caput femoris and a length measuring device which is used for measuring the femoral offset are arranged on the upper part of the base; a depth display and a length display which are electrically connected with a control circuit are arranged on the base; and the two displays display corresponding measurement parameters, so that accurate data of the caput femoris caliber of a femur, the depth of the corpus femoris and the femoral offset can be quickly and accurately measured to ensure the quality of the operation, so that a patient can obtain the best treatment effect.

Description

technical field [0001] The invention belongs to the technical field of orthopedic surgery auxiliary instruments, in particular to a measuring instrument used in hip orthopedic surgery. Background technique [0002] To conduct a comparative study on the preoperative and postoperative femoral eccentricity data of patients undergoing total hip surgery, to obtain complete data, to formulate a complete and feasible preoperative and intraoperative operation plan, to develop and improve intraoperative operations, so that patients can achieve Optimum rehabilitation is essential for treating patients with hip disorders. The tools for intraoperative eccentricity measurement are relatively rough and simple. Most of the measurement methods are based on indirect measurement of imaging data. There are many factors that affect the authenticity of the data, resulting in inaccurate measurement and affecting the performance of the artificial joint after replacement. service life. Conte...
