Digital total hip replacement device and calibration method for abduction angle and top rake of digital total hip replacement device

Abstract

The invention provides a digital total hip replacement device and a calibration method for an abduction angle and a front inclination angle thereof, and the device comprises a shaft which is provided with a working end and an operation end; the angle detection module is arranged on the shaft, is positioned between the working end and the operating end, and is used for determining an angle reference and detecting an abduction angle and a front inclination angle of the shaft relative to the angle reference in real time; the body position tracking module is used for being fixed to the bone of the patient so as to detect the angle deviation value of the body position of the patient relative to the angle reference in real time; the data processing module is in signal connection with the angle detection module and the body position tracking module and used for obtaining the abduction angle and the front inclination angle, obtaining the angle deviation value and calibrating the abduction angle and the front inclination angle based on the angle deviation value to obtain the calibrated abduction angle and the calibrated front inclination angle; and the prompting module is in signal connection with the data processing module and is used for acquiring the calibrated abduction angle and the calibrated front inclination angle and displaying the calibrated abduction angle and the calibrated front inclination angle to an operator.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a digital total hip replacement device and a method for calibrating its abduction angle and anteversion angle. Background technique [0002] At present, multiple operating steps in the basic process of total hip replacement surgery, such as grinding the acetabulum, inserting the acetabular cup trial mold, and inserting the acetabular cup prosthesis, etc., purely rely on mechanical tools and subjective experience of the operator Guarantee the validity of the results, such as whether the abduction angle and anteversion angle of the outer cup trial mold and the prosthesis are accurate, the stability of the outer cup trial mold, and whether the outer surface of the outer cup trial mold fits closely with the acetabulum, etc. However, the surgical skills and subjective experience of different operators vary greatly, resulting in different postoperative recovery effects of patie...
