Problems solved by technology

[0004] 1. X-rays cannot make a specific diagnosis for patients with sacrococcygeal deformity, fracture or narrow sacral nerve foramen;
[0005] 2. The average puncture time is too long (ranging from 20min to 3h), which increases the pain of the patient and the radiation exposure time of the operator and the patient;
[0006] 3. The number of punctures is large

Example Embodiment

[0029] Example one

[0030] Please refer to figure 1 , This implementation provides a 3D printing template for surgical puncture.

[0031] The 3D printing template includes a board body 1 and a number of cylinders 2 with piercing holes 3. The board body 1 is made up of a number of board body blocks 9; the cylinders 2 are all located on the same side of the board and arranged There are 4 joints between the plate blocks 9 and divided by the joint 4; the outer side of the column 2 is provided with an outer ring 6 which can slide relative to each other; the plate body is configured with a positioning ring 8.

[0032] A dovetail tenon 5 is constructed at the edge of the connection between the plate blocks 9 and the embedded dovetail tenon 5 structure can make the connection between the plate blocks 9 closer, and at the same time improve the overall strength of the plate.

[0033] The puncture hole 3 is constructed in the center of the cylinder 2, and the seam 4 passes through the puncture ...

Example Embodiment

[0051] Example two

[0052] Please refer to figure 2 , This implementation provides a 3D printing template for surgical puncture.

[0053] The 3D printing template includes a board body 1 and a number of detachable cylinders 2 with piercing holes 3; the board body 1 is configured with an outer ring 6, and the outer ring 6 is arranged on the same side of the board body 1, and the board body 1 The part surrounded by the outer ring 6 is hollowed out to facilitate the installation of the column 2.

[0054] The column 2 is embedded in the outer ring 6 and fixed by the outer ring 6. The seam 4 passes through the piercing hole 3 on the cylinder 2 to divide the cylinder 2. The split and detachable cylinder 2 allows the template to be removed while retaining the puncture needle after the puncture needle penetrates the puncture hole 3 during use.

[0055] The positioning ring 8 constructed on the board body needs to coincide with the position marked on the patient's buttocks when the templa...

Abstract

The invention discloses a 3D printing template for surgical puncture. The 3D printing template includes a plate body and several cylinders with puncture holes; the cylinders are divided by seams passing through the puncture holes; the outside of the cylinders An outer ring is provided; the board body is constructed with a positioning ring. Also disclosed is a method for preparing a 3D printing template for surgical puncture. The use of this puncture template can significantly reduce the operation time, and more importantly, it can significantly reduce the radiation exposure time of the operator and the patient; at the same time, according to the precise positioning before the operation, the number of punctures can be reduced, the puncture angle can be accurately determined, and the occurrence of complications can be avoided. curative effect. Especially for patients with congenital deformities or bone injuries, the feasibility of surgery can be clarified before surgery and the accuracy of puncture can be improved.

Description

technical field [0001] The invention relates to the field of puncture surgery, in particular to a 3D printing template for surgical puncture and a preparation method. Background technique [0002] The key step of sacral neuromodulation (SNM) is to accurately place the puncture needle into the sacral nerve foramen, and then place temporary electrodes and conduct tests to observe whether the intraoperative nerve reflex meets the surgical requirements. The key to the success of SNM surgery lies in accurate and rapid puncture to the best sacral foramen. [0003] The traditional puncture methods are X-ray fluoroscopy cross positioning method, sciatic notch hand touch positioning method, coccyx tip measurement positioning method and real-time ultrasound-guided puncture positioning method in the recent stage. Its shortcomings are reflected in: [0004] 1. X-rays cannot make a specific diagnosis for patients with sacrococcygeal deformity, fracture or narrow sacral nerve foramen; ...
