Abstract

The invention discloses a deep hole drilling clamp for a small orthopedic hollow screw, and belongs to the technical field of medical instrument production. The deep hole drilling clamp comprises two deep hole drilling machines and further comprises a workbench, screw clamps and centering clamps, wherein the screw clamps and the centering clamps are arranged on the workbench. A centering sleeve and the screw clamps are coaxially arranged, the two deep hole drilling machines are in sliding connection with the two sets of the centering clamps respectively, and each deep hole drilling machine and the corresponding centering clamp are coaxially arranged. In the working process, the screw clamps are rotated by 90 degrees at first, at the moment, the two ends of each screw clamp are free of hindrance, the hollow screw can be conveniently clamped, the hollow screw to be machined is coaxially fixed, then the centering clamps work, and centering of the hollow screw is achieved through the cooperation of the centering clamp sand the centering sleeves on the screw clamps. At the moment, the two deep hole drilling machines coaxial with the centering clamps work, the effect that concentric drilling is conducted on the two sides of the hollow screw at the same time is achieved, and the problem that when only one end of the hollow screw is drilled, the other end of the hollow screw is broken is prevented.

Description

technical field [0001] The invention discloses a deep hole drilling jig for small orthopedic hollow screws, which belongs to the technical field of medical device production. Background technique [0002] Hollow screw is a medical fixation device suitable for internal fixation of fractures during orthopedic surgery. During the processing of hollow screw, it is necessary to use a deep hole drill to drill it. Hollow screws usually need to be clamped and fixed with clamps when drilling holes. However, due to the relatively simple structure of the existing clamps, it is not easy to adjust, and cannot be applied to the processing of screws with different lengths, and the operation process is cumbersome, time-consuming and laborious. [0003] The Chinese utility model patent whose publication number is CN210648656U in the prior art discloses a deep hole drilling jig for hollow screws used in small orthopedic care, including a base, the inside of which is provided with a cavity, an...
