Medical orthopedic surgery positioning and punching device

Abstract

The medical orthopedic surgery positioning and punching device comprises a mounting plate and a bottom plate fixed to the lower end of the mounting plate, the mounting plate is in a knife shape, the front face of the mounting plate is rotationally connected with a first rotating shaft, and the first rotating shaft is coaxially and fixedly sleeved with a gear; a first rotating plate is fixedly connected to the position, on the front side of the gear, of the first rotating shaft in a sleeving mode, a second rotating plate is connected to the lower end of the first rotating plate through a pushing mechanism, a puncher is fixedly installed at the lower end of the second rotating plate, and an electric telescopic rod is fixedly installed on the front face of the mounting plate; the telescopic end of the electric telescopic rod is fixedly connected with a toothed plate meshed with the gear, the outer wall of the first rotating plate is fixedly connected with a pointer, and the front face of the mounting plate is fixedly connected with an angle arc plate used in cooperation with the pointer. According to the device, the punching angle and the punching depth can be freely set, the situations of punching deflection and too deep or too shallow punching are avoided, and meanwhile the situation that a patient moves randomly and influences an operation can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning and punching device for medical orthopedic surgery. Background technique [0002] In the field of orthopedics, bone drilling is required before screwing a screw or a steel plate into a patient's leg. However, the existing drilling device cannot preset the drilling angle and drilling depth according to the needs, and can only rely on the doctor himself. Drilling by yourself is prone to problems such as skewed drilling, too deep or too shallow drilling, which is easy to cause secondary damage to the patient. [0003] To this end, we propose a medical orthopedic surgery positioning and punching device to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a positioning and punching device for medical orthopedic surgery to solve the problem that the punching angle and punching depth cannot be pres...
