Orthopedic osteotomy board system and operation method

Abstract

The invention discloses an orthopedic osteotomy board system and belongs to the technical field of medical instruments. The system comprises an osteotomy board and positioning nails, and the osteotomyboard is provided with an osteotomy groove and nail holes. The invention further provides an operation method of the orthopedic osteotomy board system. According to the orthopedic osteotomy board system, the osteotomy direction and angle and the distance among the osteotomy ends are determined, the osteotomy groove limits a saw web to swing randomly, horizontal or inclined parallel osteotomy canbe precisely completed, wedge-shaped or irregular shape osteotomy can also be completed according to the design, and the system and method can be applied to intra-operative osteotomy treatment of osteotomy orthopedic surgery for congenital dysplasia of the hip joint, manual total hip arthroplasty and other surgery. The orthopedic osteotomy board system is simple in structure and convenient to operate, individuation positioning and installation can be conducted according to demands, orthopedists can conduct precise osteotomy according to support and guide which are provided by the system, convenience is provided for the surgery operation, the surgery efficiency is improved, and the burden of doctors and patients is reduced.

Description

technical field [0001] The invention relates to a medical instrument for osteotomy, in particular to a rectangular osteotomy plate system and operation method in orthopedic orthopedic reconstruction surgery, such as osteotomy orthopedic surgery for congenital hip joint dysplasia and artificial total hip joint replacement surgery. Background technique [0002] Osteotomy orthopedic surgery is widely used in the treatment of bone and joint developmental or post-traumatic deformities. Osteotomy is used to correct abduction, flexion and extension or combined deformities, such as hip preservation or joint replacement surgery for the treatment of developmental dysplasia of the hip. Osteotomy of the proximal femur is also often required. [0003] At present, there is no orthopedic osteotomy plate for this purpose. In actual operation, the angle of osteotomy and the distance between parallel osteotomy ends are usually determined by the reconstructive surgeon based on experience and f...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no orthopedic osteotomy plate for this purpose. In actual operation, the angle of osteotomy and the distance between parallel osteotomy ends are usually determined by the reconstructive surgeon based on experience and feel. There may be large deviations in orientation and positioning. The results are uneven, and the clinicians often need to waste a lot of energy to adjust the angle and trim the section after surgery, which not only increases the operation time, causes waste of manpower, but also increases the workload of the doctor. When the matching is poor, the risk of postoperative bone nonunion will increase, which will adversely affect the patient's postoperative rehabilitation and functional exercise

[0004] To sum up, the existing methods of simply relying on experience and freehand osteotomy for complicated orthopedic surgery have the defects of large error, inconvenient operation and low efficiency.
