Problems solved by technology

[0002] The guide is an indispensable tool for orthopedic surgery. Ordinary guides only have serrations on the distal end of the guide sleeve. When clinicians use ordinary guides to drill holes on the bone surface, the drill bit of the electric drill often slips, resulting in Failed, clinicians often need to repeatedly drill holes to drill the required screw holes on the smooth bone surface

Abstract

The invention discloses an orthopedic centralized drill guide, which comprises: a connecting rod, a guide sleeve and clamping claws; the outer wall of the upper end of the guide sleeve is connected and fixed with the connecting rod, and the end surface of the lower end of the guide sleeve is provided with anti-skid serrations; The jaws include a sleeve, a limit screw and a pair of arc-shaped elastic metal sheets, the two arc-shaped elastic metal sheets are fixed at the lower end of the sleeve, and the two arc-shaped elastic metal sheets are arranged symmetrically to each other; the sleeve can slide The sleeve is set on the guide sleeve, and the sleeve is fixed with the guide sleeve by a limit screw. Through the above method, the present invention can control the drill bit in the middle of the bone medullary cavity, ensure the maximum holding force of the screw, reduce surgical injury, shorten the operation time, and reduce the operation bleeding.

Description

technical field [0001] The invention relates to the field of medical drilling instruments, in particular to an orthopedic centralized drill guide. Background technique [0002] The guide is an indispensable tool for orthopedic surgery. Ordinary guides only have serrations on the distal end of the guide sleeve. When clinicians use ordinary guides to drill holes on the bone surface, the drill bit of the electric drill often slips, resulting in Failure, clinicians often need to repeatedly drill holes to drill the required screw holes on the smooth bone surface. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a centralized drill guide for orthopedics, which can control the drill bit in the middle of the bone medullary cavity, ensure the maximum holding force of the screw, reduce surgical injury, shorten operation time, and reduce surgical bleeding. [0004] In order to solve the above technical problems, a tech...
