[0007] 1) Due to the relationship between the puncture angle, it is difficult for the surgical instruments of conventional percutaneous vertebroplasty/percutaneous kyphoplasty to pass through the midline of the vertebral body. Symmetry of body height
However, this will not only cause the patient’s injury at least twice as much as that of unilateral puncture, but also increase the labor intensity of medical staff, and the patient and medical staff will receive radiation for a long time. Of course, more surgical instruments are needed for bi

Embodiment Construction

[0034] Note: "Front" in this patent application refers to the direction of the cutting part adjacent to the device for forming a cavity in the vertebral body of the present invention, and "tail" refers to the direction away from the present invention for use in the vertebral body. The direction of the cut part of the device in which the cavity is formed. "Cutting" refers to the specific method of forming a cavity in the vertebral body.

[0035] In the prior art, a balloon is used to form the vertebral body. It uses a puncture method through the skin to establish a channel extending into the vertebral body through the pedicle; an inflatable balloon is inserted into the channel; the balloon is formed after inflation An internal cavity, and the height of the vertebral body has been restored to a certain extent; after the balloon is withdrawn, bone cement is filled into the cavity, and the bone cement hardens to form a strengthening effect on the vertebral body.

Abstract

A device for forming a cavity in a centrum comprises a cutting part and a control device, wherein the cutting part is used for cutting the centrum and the control device is used for controlling the cutting part to cut the centrum. The control device comprises a bearing part used for bearing the cutting part, and the end, adjacent to the cutting part, of the bearing part is provided with a bendable portion. The bearing part comprises a direction limiting part used for controlling the bending direction of the bearing part and a limiting part used for controlling the bending angle of the bearing part. The bearing part can further comprise a protective part. The control device further comprises a manipulation assembly used for controlling the bearing part to bend. The device can effectively avoid dangers caused by bilateral puncture in the prior art, the shape of the cavity is controllable, meanwhile, damage to bone tissue is reduced, and bone cement can permeate between bone trabeculae more effectively.

Description

Technical field [0001] The invention relates to the field of medical devices, and in particular to a device for forming a cavity in a vertebral body. The equipment provided by the present invention is mainly used in minimally invasive surgical operations for the treatment of vertebral compression fractures caused by osteoporosis and accompanying intractable pain. Background technique [0002] At present, the main minimally invasive surgical methods for the treatment of vertebral compression fractures are percutaneous vertebroplasty and percutaneous kyphoplasty. [0003] Among them, Percutaneous Vertebroplasty (PVP) refers to injecting bone cement into the vertebral body through the skin through the pedicle or pedicle to increase the strength and stability of the vertebral body, prevent collapse, and relieve pain It is a minimally invasive spine surgery technique for the purpose of partially restoring the height of the vertebral body. The key step of percutaneous vertebroplasty is...
