Orthopaedic intramedullary ultrasonic lock pin aiming auxiliary device

Abstract

The invention provides an orthopaedic intramedullary ultrasonic lock pin aiming auxiliary device, and relates to the field of medical instruments. The orthopaedic intramedullary ultrasonic lock pin aiming auxiliary device comprises a shell and an ultrasonic probe, wherein a first rotating motor is fixedly connected to the inner part of the shell, an intramedullary pin body is fixedly connected tothe output end of the first rotating motor, and a second rotating motor is fixedly connected to the position, located on one side of the first rotating motor, of the inner part of the shell; and the output end of the second rotating motor extends to the side wall of the shell and is fixedly connected with a rotating disc, the top end of the rotating disc is fixedly connected with an electric pushrod, the movable end of the electric push rod is fixedly connected with a positioning rod, and the front face of the positioning rod is fixedly connected with a positioning block. By arranging the second rotating motor, the rotating disc and the electric push rod, the positioning rod is conveniently driven to rotate to detect the position of a positioning hole, the rotating accuracy is improved, and the problems that the manual rotating accuracy is not enough and the use is troublesome are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an orthopedic intramedullary ultrasonic locking nail aiming auxiliary device. Background technique [0002] The intramedullary nail is an orthopedic internal fixation device in the medical equipment. There is more than one strip-shaped decompression plane on the surface of the nail rod. The decompression plane can be from the proximal end of the intramedullary nail rod to the distal end of the intramedullary nail rod. A locking screw positioning screw hole is set at the proximal end of the intramedullary nail rod. , Connecting sets of positioning slots. [0003] However, the current orthopedic intramedullary ultrasonic locking nails are generally rotated by manpower during use. Not only the rotation accuracy is not enough, but also the user's operation strength is increased, which makes it very troublesome to use. , the operation process is very cumbersome and the fixing effect i...
