Embodiment Construction

[0012] In order to be safe and hygienic, stable and reliable, all parts of the present invention are made of titanium alloy, wherein the rotating handle 1 and the hollow screw 2 are welded together, and the function of the rotating handle 1 is to make the hollow screw 2 fit by rotating the rotating handle 1. The cutting edge 4 and thread 5 at the bottom enter into the patient's spine, and the medical personnel need to apply downward pressure while turning the handle 1, so that the hollow screw 2 can easily enter the patient's spine, and a top end is processed at the bottom of the core rod 3 7. The role of the core rod 3 is to guide, the role of the top 7 is to position, the role of the cutting edge 4 is to play the role of self-tapping, and the role of the thread 5 is to stabilize and fix the hollow screw 2 after entering the patient's spine The effect of sawtooth 6 is exactly the superficial layer of cutting bone.

[0013] To sum up, the present invention not only greatly red...

Abstract

The invention belongs to a medical tool, and specifically relates to a positioning, guiding and hole-reaming screw tap which is used when medical workers in an operating room operate on a patient. The positioning, guiding and hole-reaming screw tap is composed of a rotary handle and a hollow screw. The positioning, guiding and hole-reaming screw tap is characterized in that the rotary handle is fixed on the upper part of the hollow screw, a core bar is installed in the hollow screw, the bottom of the core bar is processed to form a tip, and the bottom of the hollow screw is processed to form a cutting edge and a screw thread. Because the core bar is installed in the hollow screw and the bottom of the core bar is processed to form the tip, when the screw tap is used, the tip is directed at the spine position of the patient firstly, then the rotary handle is rotated, and the hollow screw enters the spine of the patient. In conclusion, pain of the patient is greatly reduced, the working efficiency of medical workers is greatly improved, and medical accidents are avoided.

Description

technical field [0001] The invention belongs to medical instruments and tools, in particular to a positioning-guiding reaming screw tap used by medical personnel in operating rooms when performing operations on patients. Background technique [0002] Now the reaming tap used by the medical staff in the operating room of the hospital when performing operations on the patient has a simple structure and a single function, and cannot meet the requirements of the operation. This brings inconvenience to the medical staff and also brings pain to the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a convenient, stable and reliable positioning guide reaming tap. [0004] The present invention is achieved in the following way: a positioning-guided reaming tap is composed of a rotating handle and a hollow screw, and its characteristics are: a rotating handle is fixed on the upper part of the...
