Robot reduction system for multi-segmental fractures

Abstract

The invention discloses a robot reduction system for multi-segmental fractures, which comprises an operating bed. A mechanical arm base and a plurality of temporary fixing device bases, which are respectively used for mounting a mechanical arm and temporary fixing devices, are arranged on one side of the operating bed; and the tail end of the mechanical arm is connected with a broken bone clampingdevice. By means of a temporary reduction device, a plurality of fracture segments can be respectively fixed so as to avoid uncertain factors caused by traditional surgical incision reduction or bonetraction reduction.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary robots, and in particular relates to a robot reset system for multi-segment fractures. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Multi-segment fracture is an unstable fracture caused by high-energy violence. Because the broken bone is broken into multiple segments, the position of the broken bone is difficult to control, and the stability after reduction is poor. It is easy to leave various sequelae after surgery. [0004] According to the inventor's understanding, at present, for the reduction of multi-segment fractures, surgical methods are often used to select different surgical approaches according to different positions of the broken bones to expose the fracture ends, thereby achieving the purpose of accurate reduction under direct vision. ...

Problems solved by technology

[0003] Multi-segment fracture is an unstable fracture caused by high-energy violence. Because the broken bone is broken into multiple segments, the position of the broken bone is not easy to control, and the stability after reduction is poor. It is easy to leave various sequelae after surgery.

[0004] According to the inventor's understanding, at present, for the reduction of multi-segment fractures, surgical methods are often used to select different surgical approaches according to different positions of the broken bones to expose the fracture ends, thereby achieving the purpose of accurate reduction under direct vision. However, this reduction There are problems such as large trauma and serious damage to the blood supply of the fracture segment, which can easily cause delayed union or nonunion of the fracture.

Although there has been a way of using bone traction to pass through the bone with a threaded needle and achieve the purpose of reduction through traction, for multi-segment fractures, due to the large number of fracture segments, except for the proximal fracture segment, other fracture segments It is difficult to control the target position; moreover, when a certain fracture segment is reset, it is easy to affect the adjacent fracture segment, for example, the adjacent fracture segment that has been reset is moved
