Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an orthopedic 3D surgical guide-assisted bone drilling and positioning device. Background Technology

[0002] 3D-printed surgical guides have demonstrated exceptional precision in orthopedic surgery, particularly in bone drilling and positioning. Their drilling, osteotomy, and positioning functions effectively guide surgical procedures, ensuring instruments avoid critical tissues such as blood vessels and nerves. They are widely used in various subspecialties, including trauma orthopedics and spinal surgery. Clinical data shows that in total knee replacement surgery, using 3D-printed surgical guides significantly reduces lower limb alignment deviations, elevating surgical accuracy to new heights. Therefore, using 3D-printed surgical guides in conjunction with auxiliary bone drilling and positioning devices has become standard practice. This combination further enhances surgical precision, improves safety and reliability, and provides surgeons with more convenient and efficient surgical tools.

[0003] Clinically, the common method for drilling is to fix the area to be drilled on the patient and then use a drill to drill the hole. Theoretically, to ensure the accuracy and stability of the hole, the drill should drill perpendicularly along the drilling surface. However, in actual operation, due to the complexity of bone structure, interference from soft tissues, and differences in the surgeon's experience, it is difficult to maintain the perpendicularity of the drill at all times. This often leads to deviations during the drilling process. The occurrence of deviations not only affects the surgical outcome but may also increase the patient's pain and surgical risks. Therefore, an orthopedic 3D surgical guide-assisted bone drilling positioning device is proposed to solve the above-mentioned problems. Utility Model Content
