Problems solved by technology

[0004] 1. The front end of the bone drilling needle is quite sharp, and it is easy to puncture other tissues
[0005] 2. Although the outer casing of the larger bone drilling needle can be used as the working tube, the probability of causing collapse and damage to the surrounding bone tissue is relatively higher.
[0006] 3. Physicians face a huge psychological burden when facing sharp and long tools during surgery, and are prone to mistakes
[0007] 4. At present, there is no set of safe and stable bone drilling and reaming tool devices for physicians to assist

Embodiment Construction

[0032] In FIG. 1 , a percutaneous guided bone reaming tool device 10 of the present invention includes a blunt guide pin 20 , a guide screw tube 30 , and a handle 40 . One end of the blunt guide pin 20 is a blunt spherical end 21, the center of the guide screw tube 30 has a through hole 31, and one end forms a flat taper 32, and the outer surface of the tube body is formed from the flat taper 32 to the other end. There is a thin thread section 33, and the other end is provided with a force applying portion 34. The handle 40 is provided with a seat 41, which can be movably connected with the force applying portion 34 of the guide screw tube 30. The seat 41 There is a through hole 42 , the blunt guide pin 20 can move through the through hole 42 , and pass through the flat head cone portion 32 along the through hole 31 of the guide screw tube 30 .

Abstract

The present invention relates to a percutaneous guided bone reaming tool device and its method. It mainly includes a blunt point guide pin and a guide screw tube, one end of said guide screw tube is made into a flat cone portion, its external surface is equipped with a helical toothed section. Said blunt point guide pin can be passed through skin and inserted into a bone tissue, said guide screw tube can be covered into said blunt point guide pin, and said flat cone portion and said helical toothed section can be clutched in said bone tissue, so that a working tube whose tube diameter can be covered into said guide screw tube can be punctured into said bone tissue along said guide screw tube.

Description

technical field [0001] The present invention relates to a percutaneous guided bone reaming tool device and method, in particular to a percutaneous guided and enlarged perforation tool with a blunt guide pin and a guide screw tube, which is applied to a bone tissue. Skin-guided bone reaming tool device and method. Background technique [0002] For the traditional spinal grouting surgery, for the doctor, in the whole process, the real most important and the most critical thing is how to safely and reliably make the tool pierce the hard cortical bone at the pedicle of the vertebral joints. Once it can be safely Through the hard cortical bone, other actions following the operation belong to the controllable and safer grouting work. [0003] At present, the bone puncture tools used by general doctors all use a bone drilling needle to directly puncture into the predetermined vertebral joint vertebral body from the outside of the skin under the perspective of an X-ray machine inst...
