Background

With the development of medical technology and the popularity of minimally invasive surgical concepts, spinal surgical approaches have transitioned from open surgery to minimally invasive techniques.

Compared with the traditional spine operation, the minimally invasive spine operation has the advantages of small incision, less bleeding, small tissue wound, no influence on the stability of the spine, and quick postoperative function recovery. And accurate preoperative positioning is particularly important. If the positioning is not accurate, unnecessary damage to the posterior spinal structures is caused, thereby increasing injury. Such as percutaneous pedicle screw implantation, currently still rely on repeated fluoroscopy to determine the depth, direction, etc. of lead placement. Therefore, extra damage caused by repeated puncture is increased, and medical care personnel and patients are exposed to X-ray radiation for many times during operation.

Furthermore, the puncture rod body is in a hollow cuboid shape.

Furthermore, a hole is formed in the adjusting knob, the inner diameter of the adjusting knob is the same as that of the puncture sleeve, and the adjusting knob is connected with one end of the puncture sleeve.

Furthermore, the adjusting knob is made of a non-developing material.

Further, the puncture body of rod includes fixed side and regulation side, the fixed side that the metal material was made is adopted to the fixed side, adjust the side and adopt the regulation side that the material was made not developed in the perspective.

Furthermore, the inner surface of the puncture rod body is provided with threads, and the adjusting knob can drive the puncture sleeve to rotate and move in the puncture rod body through the threads.

Further, the end surfaces of both ends of the hollow rectangular parallelepiped shape are arc-shaped.

Furthermore, the structure of the adjusting knob is a hollow structure.

Further, the kirschner wire is a common kirschner wire commonly used in orthopedic surgery.

Compared with the prior art, the utility model has the advantages of it is following:

(1) can conveniently adjust and position puncture position and direction, reduce ray exposure when shortening the operation, it is better to medical care and patient's security.

(2) The structure is big, small and the shape is all attached to the spinal surgery, the operation is simple and convenient, the use is friendly, and the learning curve is mild.

(3) The material is scientific and reasonable in use, and visual interference generated under development is avoided.
