Ring Groove Periosteal Stripper

Abstract

The invention discloses a circular-groove periosteal detacher. The circular-groove periosteal detacher comprises a handle, a detaching head of an arc-shaped sheet structure, wherein the radian of thedetaching head is 160-200, one end of the outer side wall of the detaching head is connected with one end of the handle, the handle is arranged in the chord length direction of the detaching head, andthe end, away from the handle, of the detaching head is of a blade-shaped structure. The radian of the detaching head is 170-190, the radius of the circle where the detaching head is located is 2.5-5cm, and the width of the detaching head is 0.5-1 cm. The circular-groove periosteal detacher is simple in structure and convenient to use, can make the bone and the periosteal and surrounding tissuescompletely separated and make operation smoother and more accurate, and meanwhile can be prevented from slipping away from the bone and damaging the periosteal and surrounding tissues of the bone.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical equipment. More specifically, the present invention relates to an annular groove periosteal stripper. Background technique [0002] Clinically, especially in orthopedic surgery, periosteal strippers are often used to partially strip the periosteum and cortical bone at both ends of the fracture through the periosteal stripper, which is convenient for surgical operations. The periosteum is a thin layer of elastic knot tissue that surrounds the surface of all bones other than the joints, and the joints are replaced by cartilage. The periosteum contains osteoblasts, which can produce new bone cells for growth and repair, and play an important role in bone growth and proliferation. [0003] Periosteal stripper is one of the most commonly used medical devices in orthopedic surgery. During orthopedic surgery, it is often necessary to strip the periosteum at both ends of the fracture. The tr...

Problems solved by technology

The traditional periosteum stripper is mostly a long strip of metal equipment, and its cutting edge is opened at the top. However, in orthopedic surgery, the handle of the traditional long strip periosteum stripper will affect the user's handling of the bone, and it is prone to operating errors. And the top is set as a cutting edge. It is not easy to fix the stripper during the operation. The stripper will deviate from the surface of the backbone and slide to the deep tissue, which will damage the periosteum and surrounding tissues.
