Scale screw tap for orthopedics department

Abstract

The invention provides a scale screw tap for the orthopedics department. The scale screw tap comprises a tap head, a tap body, threads, scales and a handle, wherein the handle is the handheld part ofthe scale screw tap for the orthopedics department provided by the invention, the tap body is arranged at the front end of the handle, the threads are arranged on the tap body, the tap head is arranged at the front end of the tap body, a groove is further formed in the tap body, and the scales are marked in the groove. When the scale screw tap for the orthopedics department provided by the invention is adopted for tapping, break-through feeling is generated when the screw tap penetrates through the cortex on the opposite side, after tapping is finished, the scale on the screw tap is memorized,a screw with corresponding length is selected according to the scale value, and after tapping, the operation of measuring the depth of a drilled hole by adopting a depth measuring ruler is not needed.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to an orthopedic graduated screw tap. Background technique [0002] In orthopedic surgery, threaded screws are commonly used to fix the steel plate or the injured bone surface. Before the fixation, a tap is used to make a hole. The current tap only plays the role of a hole in the process of treating fractures. Measuring the depth of the hole and selecting a screw of the corresponding length is time-consuming, laborious, and inaccurate, affecting the effect of treatment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a graduated tap that can be used for depth measurement while drilling a hole, including a cone head, a cone, a screw thread, a scale and a handle. It is the hand-held part of the orthopedic graduated tap according to the present invention. A cone is provided at the front end of t...
