Clamping and fixing device based on robot fracture reduction

Abstract

The invention relates to a bone reduction assisting device based on a medical robot, which comprises a near-end bone block fixing mechanism and a far-end bone block fixing mechanism, each of the near-end bone block fixing mechanism and the far-end bone block fixing mechanism comprises at least two sets of sleeves arranged on a support in parallel, threaded needles are arranged in the sleeves, and connecting grooves perpendicular to the threaded needles are formed in the support; the temporary connecting mechanism comprises a near-end fixing rod and a far-end fixing rod which are connected through a connecting rod and a first spherical joint, the near-end fixing rod is detachably connected with a connecting groove of the near-end bone block fixing mechanism, and the far-end fixing rod is detachably connected with a connecting groove of the far-end bone block fixing mechanism; the near-end bone block fixing mechanism is fixed to the operating bed body through the operating bed fixing mechanism, and the far-end bone block fixing mechanism is detachably connected with the medical robot body through the robot connecting mechanism. The near-end bone block fixing mechanism, the far-end bone block fixing mechanism and the threaded needle are used for achieving the ideal bone reduction effect through extremely small trauma.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a clamping and fixing device based on robot fracture reduction. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Fracture is a common clinical disease, and the integrity and continuity of the bone are mostly interrupted by external force. Currently, there is no good fixation of bone fragments and devices that are convenient for linking with robots when treating fractures. [0004] Fractures are usually accompanied by the movement of bone fragments, and the treatment needs to restore the normal positional relationship of the distal and proximal bone fragments.

Problems solved by technology

[0003] Fracture is a common clinical disease, and the integrity and continuity of the bone are mostly interrupted by the external force of the bone. At present, there is no good fixation of the bone block and a device that is convenient for linking with the robot in the treatment of fractures.

[0004] Fractures are usually accompanied by the movement of bone fragments, and the treatment needs to restore the normal positional relationship of the distal and proximal bone fragments. However, traditional treatment methods often destroy local blood supply, resulting in fracture nonunion or delayed union. Robots are increasingly The more it is used in clinical fracture treatment, the use of the robot's mobile positioning function makes the reset of the bone block more accurate, but at present, there is a lack of clamping device between the bone block and the robot, making it difficult for the robot to perform its functions
