Abstract

The invention provides a three-dimensional printed minimally invasive guide template and a making method thereof. The making method comprises the steps that scanning is conducted on a target part to obtain a three-dimensional image of the target part; reconstruction is conducted according to the obtained three-dimensional image, and a three-dimensional model of the target part is obtained; needle insertion directions, needle insertion positions and needle insertion depths are planned according to the reconstructed three-dimensional model and requirements of doctors, and dosage is conformally distributed on source particle positions; a guide template digital model is built according to the reconstructed three-dimensional model and the planned needle insertion directions, needle insertion positions and needle insertion depths; the guide template digital model is printed into the three-dimensional printed minimally invasive guide template by means of a 3D printing technology. According to the three-dimensional printed minimally invasive guide template and the making method thereof, the reliability and effect of implanting treatment can be improved, operation labor intensity is reduced, the operation time is shortened, and a risk is reduced.

Description

technical field [0001] The present invention relates to the technical field of minimally invasive medical treatment, and more specifically relates to a 3D printing minimally invasive guide template and a manufacturing method thereof. Background technique [0002] Radiation therapy (radiotherapy) is one of the important treatments for tumors. In order to minimize the side effects of radiotherapy and the damage to normal tissues caused by radiotherapy, a radioactive seed implantation treatment technology (hereinafter referred to as seed implantation) has been developed. [0003] Seed implantation is a treatment in which a radioactive source is implanted inside a tumor to destroy it. The particle implant therapy technique involves a radioactive source, the core of which is radiating particles. Seed implantation mainly relies on a directional system to implant radioactive seeds into the tumor body, and emits continuous, short-distance radiation through a micro-radiation source...
