Abstract

The invention discloses a deep hole drilling jig for small orthopedic hollow screws, which belongs to the technical field of medical device production. It includes two deep hole drilling machines, and also includes a workbench and a screw fixture and a centering fixture arranged on the workbench. The centering sleeve is coaxially arranged with the screw fixture. The centering fixture is provided with two groups, two The deep hole drilling machines are respectively slidably connected with two sets of centering jigs, and each deep hole drilling machine is coaxially arranged with the centering jigs. When working, first rotate the screw clamp by 90 degrees. At this time, the two ends of the screw clamp are not hindered, which is convenient for clamping the hollow screw, and the hollow screw to be processed is fixed coaxially. The centering sleeve cooperates to realize the centering of the hollow screw. At this time, the two deep hole drilling rigs set coaxially with the centering fixture work to realize the effect of concentric drilling on both sides of the hollow screw at the same time, preventing only the hollow screw from being drilled. Drilling one end of the screw causes the other end to break.

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...
