AI Technical Summary

Technical Problem

Existing osteotomy guides around the knee joint are insufficient in terms of personalized fitting and locking stability, and cannot meet the needs of precise control and intraoperative positioning.

Method used

A periarticular osteotomy guide plate for the knee joint was designed, employing a stepless adjustment mechanism and a ratchet-pawl locking mechanism to achieve stepless adjustment and reliable locking of the guide pin and Kirschner wire. Combined with the fine-tuning clamping of the arc-shaped clamp and threaded rod, it can adapt to different anatomical structures and improve clamping stability.

Benefits of technology

It achieves precise positioning of the guide pin and Kirschner wire, reduces the number of intraoperative fluoroscopy sessions, improves the safety and efficiency of the surgery, adapts to different osteotomy planes and orthopedic schemes, and avoids the risk of guide plate displacement.

Abstract

The application discloses a knee joint surrounding osteotomy guide plate and belongs to the field of surgical auxiliary instruments. The knee joint surrounding osteotomy guide plate comprises a first clamping arm, a crossbar is fixed on the first clamping arm, a second clamping arm is slidably arranged on the side of the crossbar away from the first clamping arm, a locking mechanism is arranged between the second clamping arm and the crossbar, a first stepless adjusting mechanism is arranged on the side of the crossbar close to the first clamping arm, the first stepless adjusting mechanism comprises a first through groove penetrating the crossbar in the up-down direction and a first guide groove penetrating the crossbar in the front-back direction, at least one first sleeve is slidably arranged in the first through groove, the first sleeve is used for penetrating a guide needle, first guide blocks matched with the first guide groove are arranged on the front and back sides of the first sleeve, a first screw rod is fixed to the outer end of the first guide blocks, and a first butterfly-shaped locking piece is threadedly connected to the first screw rod. The application realizes stepless adjustment of the positioning needle placement position, completely breaks through the fixed point limitation and accurately adapts to personalized osteotomy requirements.
