Problems solved by technology

The existing problems are as follows: ①Simple CT-guided implantation of radioactive seeds is based on personal experience. Due to the interference of ribs or anatomical deconstruction, it is difficult to achieve a completely parallel arrangement of seed needles; ②The seed implantation is based on preoperative The treatment plan is carried out, but the patient's position, respiratory movement or bleeding, pneumothorax, etc. in the actual operation can cause a large deviation between the intraoperative particle implantation and the preoperative plan; It is also different, there is no particle implantation guide template that can fully match the body surface

Abstract

The invention discloses a moldable 3D guiding template for particle transplanting. The moldable 3D guiding template comprises a needle inserting region, wherein needle inserting boards are arranged onthe needle inserting region; needle holes are formed in each needle inserting board; every two adjacent needle inserting boards are connected through a first air sac; one circle of second air sac isarranged on the periphery of the needle inserting region, and is connected with the needle inserting boards; isolation belts are arranged between the second air sac and the first air sac; each throughhole for guiding air is formed in the corresponding isolation belt; a plurality of molding balls are stuffed in the first air sac and the second air sac; a wind pipe is arranged on the second air sac; and a valve is arranged on the wind pipe. The moldable 3D guiding template for the particle transplanting disclosed by the invention is used for assisting radioactive particles to treat tumors; according to different body surface curves, real-time molding is performed, so that particle needles are convenient to insert into the tumor of a patient, danger organs are effectively avoided, the distribution of the particle needles is more scientific, and the radiation dose of the tumor is more uniform.

Description

technical field [0001] The invention relates to the technical field of tumor radiotherapy, in particular to a 3D guide template for implanting plastic particles. Background technique [0002] Radioactive particles have been used to treat tumors for more than 100 years. Radioactive particles are percutaneously punctured, and timely addition of particles to the target area or dangerous area can be performed during the operation, and the location or location of dangerous organs can be effectively avoided, truly realizing the tumor target. The concept of radiation therapy with higher dose in the area and less damage to surrounding normal tissues. Preliminary practice has proved that a good goal of salvage therapy can be achieved, and the side effects are acceptable. The existing problems are as follows: ①Simple CT-guided implantation of radioactive seeds is based on personal experience. Due to the interference of ribs or anatomical deconstruction, it is difficult to achieve a c...
