Embodiment Construction

[0024] Such as Figure 1 to Figure 6 As shown, the present invention discloses a 3D printed transforaminal mirror targeted puncture guide plate for percutaneous surgery, including a 3D printed base 8 and a guide plate body 6, the guide plate body is supported by the base and positioned on the human body; the base It is in the shape of a rhombus, and there is a vertical positioning column 10 at the intersection of its diagonals, and a connecting hole 9 for connecting with the medical adhesive sheet to realize the base fixing is respectively provided at the vertices of the four corners and the lower end surface of the positioning column; the guide plate body It is strip-shaped and is composed of a positioning section 5 for connection and positioning with the base and a puncture guide section 6 for puncture positioning. The center of the positioning section of the guide plate has a positioning hole 4 for the base positioning column to extend into; the puncture guide The front end...

Abstract

The invention relates to a 3D printing intervertebrale foramen mirror targeting puncturing percutaneous surgery guide plate, and further provides a puncturing method by adopting the surgery guide plate. The 3D printing intervertebrale foramen mirror targeting puncturing percutaneous surgery guide plate comprises a base and a guide plate body; the guide plate body is supported by the base and positioned on a human body, the guide plate body is internally formed by a positioning segment connected with the base and a puncturing guide segment used for puncturing and positioning, a positioning groove formed in a guide plate positioning hole is exactly matched with a positioning protrusion of the base in an embedded mode, and then puncturing is carried out along an oblique guide channel of a guide pipe arranged at the front end of the puncturing guide segment. The 3D printing intervertebrale foramen mirror targeting puncturing percutaneous surgery guide plate and the puncturing method have the advantages that a puncturing route is decided by the 3D printing percutaneous surgery guide plate before surgery is carried out, the puncturing depth is measured, nerves and vessels are prevented from being damaged in the surgery, puncturing is carried out along guide holes in the surgery, the surgery time can be obviously shortened, the fluoroscopy radiant quantity is reduced, preconditions are provided for hole expanding, pipe arranging and under mirror operating in follow-up periods, and meanwhile the damage probabilities of the nerves and the vessels are reduced.

Description

technical field [0001] The invention relates to a 3D printed transforaminal mirror targeted puncture guide plate for percutaneous surgery, and also relates to a puncture method using the guide plate. Background technique [0002] The application of 3D printing in the medical field is gradually spreading and deepening. The reproduction of human body parts is a highly customized product. Through 3D printing, these parts can completely fit and integrate with the body. [0003] For example, the transforaminal minimally invasive spinal technique can maintain the integrity of the annulus fibrosus and maintain the stability of the spine to the greatest extent. It has the least trauma to the patient and the best effect in similar operations. At present, the international spinal surgery field has recognized that endoscopic transforaminal nucleectomy will develop into the leading surgical method in this field in the future. [0004] This technology can be divided into three parts...
