3D print template for surgical puncture and preparation method

Abstract

The invention discloses a 3D print template for surgical puncture. The 3D print template comprises a template body and multiple columns with puncture holes; the columns are divided by seams penetrating through the puncture holes; outer rings are arranged on the outer sides of the columns; the template body is provided with locating rings. The invention further discloses a preparation method of the 3D print template for surgical puncture. By using the puncture template, the surgery time can be obviously shortened, and more importantly, the radiation exposure time of surgeons and patients can be obviously shortened; meanwhile, according to preoperative precise positioning, the puncture times can be reduced, the puncture angle is accurately determined, complications are avoided, and the curative effect is improved. Particularly, for patients suffering from congenital malformation and skeletal injury, the operation feasibility can be defined before an operation, and the puncture accuracy is 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; ...

AI Technical Summary

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, and it is very likely that hematoma or scars will appear around the nerve due to puncture injury, which will affect the occurrence of nerve stimulation conduction;

[0007] 4. After the puncture needle is implanted into the neural foramen, it is impossible to predict whether it is parallel to the nerve root, which may affect the postoperative test results
