AI Technical Summary

Technical Problem

The existing guide plates cannot effectively consider individual differences when treating long bone fractures, resulting in poor surgical reduction and fixation effects. It is difficult for the existing technology to achieve accurate fracture reduction and fixation, resulting in insufficient intraoperative strength and unstable reduction, affecting the healing effect.

Method used

By obtaining patient CT data, using 3D modeling software for fracture simulation reduction, designing personalized reduction guides, including model parts of round bone needles, fixing needles and screws, and using 3D printing technology to manufacture guides to ensure accurate patching of guides and fracture sites. Combined and fixed.

Benefits of technology

It improves the accuracy of surgical operations, reduces the patient's pain, reduces the risk of poor healing, ensures the fracture reduction and fixation effect, shortens the wound healing time, and improves the treatment effect.

Abstract

The present invention discloses a method for constructing a guide plate for reduction and fixation of long bone fractures, and relates to the technical field of orthopedic medical device design. The present invention includes obtaining long bone images and presetting screws before surgery; designing and making the guide plate; distinguishing the indications of the guide plate; designing the shape of the guide plate; arranging the positioning pins; arranging the bone round pins; setting the skin incision holes of the guide plate; designing the disassembly of the guide plate; and making the guide plate. The present invention uses 3D digital technology to complete the screw placement and reduction in one go, minimizes the exposure field during surgery, reduces damage to soft tissues, greatly reduces postoperative recovery time, alleviates patient pain, reduces the risk of poor wound healing after internal fixation, allows patients to stand up on the ground as soon as possible to exercise lower limb function, and accelerates the healing of fractures.
