AI Technical Summary
Existing technology cannot adjust the angle between the ribs and thoracic vertebrae through fine-tuning. Traditional screw fixation methods face problems of insufficient holding force and cumbersome operation in the specific anatomical location of the ribs, especially in cases of osteoporosis or short stumps, resulting in prolonged operation time and poor fit.
An artificial rib head prosthesis was designed, employing an anastomosis structure and a locking structure. The locking structure includes a micro-motion knob and an adjustment clasp. By rotating the micro-motion knob, the angle and position between the rib and the spinal implant can be adjusted. Combined with the design of wedge-shaped expansion blocks and sliding blocks, fine adjustment and fixation can be achieved.
It improves the fit between rib and spinal implants, reduces damage to healthy bone tissue, simplifies surgical procedures, shortens surgical time, and enhances fixation.
