AI Technical Summary
In existing techniques, when the patella is moved by hand, the hand is directly exposed to X-rays, which affects the quality of fluoroscopic imaging and causes radiation damage to the surgeon. Furthermore, there is a lack of accurate assessment of the surgical efficacy.
The device employs a patellar bolster, which includes a handle, an extension rod, and a bolster. The wooden extension rod and the curved bolster are used to move the patella during X-ray examinations. The bolster force is monitored in real time by a force gauge and a display screen, avoiding direct hand contact with the patella.
This method achieves the goal of not affecting image quality during X-ray fluoroscopy measurements, reducing surgeons' radiation exposure, and improving the accuracy and consistency of surgical efficacy assessment.
