Problems solved by technology

The ruler measurement method is based on a specially designed reference ruler and protractor, and the device structure is relatively simple; but it can only perform static measurement of the installation angle of the artificial acetabulum, and the measurement accuracy is limited and the stability of the installation process is not guaranteed.
The bracket-guided method can improve the stability of the artificial acetabular installation by using the installation hammer guide; however, the bracket structure itself is bulky and the measurement accuracy is not high
The pelvic coronal Steiner needle method can effectively improve the accuracy of the installation angle of the artificial acetabular during operation by means of the pelvic coronal position positioning device, the Steiner needle characterization device and the angle measurement device; Inconvenience and other issues
The pelvic posture electronic measurement method includes an initial posture measurement device for determining the front plane of the pelvis, a positioning pin measurement device for determining the relative posture of the pelvis, an installation angle measurement device for determining the spatial posture of the artificial acetabulum, and a software for real-time posture calculation and processing of the pelvis and artificial acetabulum. The hardware system, with the help of wireless data transmission and computer display, can provide dynamic and visual guidance for the installation angle of the artificial acetabulum; however, the whole set of devices has practical problems such as complex system configuration, complex data processing, high performance requirements for software and hardware, and high investment costs

Embodiment 1

[0041] In this embodiment, see figure 1 The hardware functional frame diagram shown. An acetabular anteversion angle and abduction angle measurement system in hip arthroplasty, comprising a plaster binding band, a reference module 1, a measurement module, a display module and a hip arthroplasty surgical instrument.

[0042] The reference module 1 includes a reference base, a reference end cap 1A, a switch 1E, a battery 1C and a reference circuit board 1B, and is mainly used to describe the posture of the pelvic reference plane. The reference base is provided with battery mounting holes, reference circuit board mounting holes, switch fixing slots and reference end cover 1A fixing holes, so the battery 1C and the reference circuit board 1B can be fixed on the base Inside, the switch 1E can be fixed on the side of the reference base, and the reference end cover 1A is fixed on the top of the reference base as the installation shell of the reference module 1 .

Embodiment 2

[0055] In hip replacement surgery, the method for measuring acetabular anteversion angle and abduction angle in artificial hip replacement surgery by using the electronic system of the first embodiment includes the following procedures:

[0056] First, fix the measurement module and the reference module 1 through the calibration slot, start the calibration, and manually eliminate errors; secondly, install the calibrated reference module 1 on the plaster, and bind it to the waist of the human body at three points; then Install the measurement module on the hip replacement surgical instrument, adjust the anteversion angle calibration rod and the abduction angle calibration rod to the desired angle, and input the angle into the display module; finally observe the angle deviation of the display module to adjust the acetabular false The implant rod was successfully implanted into the acetabular prosthesis.

[0057] This embodiment can achieve the following technical effects:

Description

technical field [0001] The invention relates to the technical field of medical electronics, in particular to a system and method for measuring the anteversion angle and abduction angle of the acetabulum in artificial hip joint replacement. Background technique [0002] Artificial hip replacement plays an important role in the rehabilitation and life of patients with hip dysfunction such as femoral head necrosis. In artificial hip arthroplasty, accurate measurement of the anteversion angle and abduction angle of the artificial acetabulum relative to the pelvis to reconstruct a good hip rotation center is of great significance for preventing postoperative hip joint wear and dislocation. [0003] In the current artificial hip arthroplasty, the anteversion angle and abduction angle of the artificial acetabulum are mainly determined by visual inspection based on the physician's experience, and are also affected by factors such as the difficulty in determining the pelvic posture, ...
