Abstract

The invention relates to a connecting device. The connecting device comprises an array bracket, a reflective ball mounting bracket, a rotary handle, an array locking bolt and an array connecting rod, wherein the array bracket is used for installing a reflective ball array; the reflective ball mounting bracket is used for mounting a reflective ball; the rotary handle is used for locking and unlocking the connecting device; one end of the array locking bolt is connected to the rotary handle, and the other end of the array locking bolt is screwed into the bottom of the array bracket and is used for connecting the rotary handle and the array bracket. the array locking bolt is used for sealing a cover; and one end of the array connecting rod is a regular hexagon boss used for connecting an array bracket body, and the other end of the array connecting rod is provided with threads used for connecting a bone needle clamp. The array connecting rod adopts a polygonal boss design, and various angles can be selected when the array connecting rod is connected with the array bracket main body. In a joint operation, the position and the direction of a spicule nailed into a bone vary from person to person, the multi-angle connecting device is adopted to connect the bone needle clamp and a reflective ball bracket, so that a high-precision optical positioning instrument can identify the reflective ball on the array bracket at the best working angle, and more accurate parameters are provided for doctors to use a robot to navigate the orthopedic surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a connecting device used for connecting bone needle fixtures and reflective ball arrays in robot-navigated orthopedic operations. Background technique [0002] In joint surgery, the position and direction of the bone needle nailing into the bone vary from person to person. The angle of the existing bone needle fixture is fixed, and it is difficult to ensure the optimal working angle to identify the reflective ball on the array bracket. [0003] Therefore, it is necessary to provide a multi-angle connecting device to connect the bone needle fixture and the reflective ball bracket, so as to ensure that the high-precision optical positioning instrument can recognize the reflective ball on the array bracket at the best working angle, and provide robots for doctors to use. Orthopedic surgery provides more precise parameters. Invention content: [0004] In order to solve...
