Longitudinal minimal-invasion bone cutter for tubular bones

Abstract

A longitudinal minimal-invasion bone cutter for tubular bones comprises a bone cutting end bone cutting device and far end positioning devices. The bone cutting end bone cutting device is slidingly sleeved on a positioning adjusting guide rail which is in a long-strip shape, a sliding groove is arranged in the middle of the positioning adjusting guide rail along the length direction, and scales of the positioning adjusting guide rail are arranged along the sliding groove. The far end positioning devices are symmetrically sleeved at two ends of the positioning adjusting guide rail slidingly. By means of the longitudinal minimal-invasion bone cutter, medical workers can perform longitudinal bone cutting operations on the tubular bones according to treatment needs, and the longitudinal minimal-invasion bone cutter is convenient to operate. When the operations are performed, the longitudinal minimal-invasion bone cutter provides convenience for transverse traction of bone blocks and meets needs of angiitis treatment. The bone cutting operations performed by the aid of the longitudinal minimal-invasion bone cutter belong to minimal-invasion operations, do not damage nerves, blood vessels, soft tissues and periostea, have small invasion, facilitate reconstruction and union of bones, and meet needs of longitudinal traction treatment of the tubular bones. By means of the longitudinal minimal-invasion bone cutter, safety and accuracy of the longitudinal bone cutting operations of the tubular bones are improved, medical workers can conveniently perform the operations, and the operation effect is guaranteed.

Description

technical field

[0001] The invention relates to an orthopedic surgical instrument, in particular to an osteotomy device for tubular bone. Background technique

[0002] In the past, surgical osteotomies for tubular bones used traditional orthopedic surgical instruments such as straight saws, pendulum saws, ring saws, reciprocating saws, osteotomes, rongeurs, amputators, osteotomists, and bone drills. Open incision, large surgical wound, many bone defects at the osteotomy site, easy to damage the soft tissue and periosteum around the wound, resulting in hematoma and prolonged wound healing, which directly affects postoperative recovery.

[0003] At present, there is no osteotomy device specially for osteotomy of tubular bone. During osteotomy, due to the relative length of tubular bone, the size of the osteotomy increases accordingly, so it is difficult to perform osteotomy for deformed bone correction surgery on such long bones; especially in the treatment of veins. In the ...
