Puncture implantation auxiliary device for radiotherapy

Abstract

The invention discloses a puncture implantation auxiliary device for radiotherapy, and relates to the technical field of medical instruments. The device comprises a radiotherapy platform, the radiotherapy platform is also provided with an anti-shake mechanism and an auxiliary implantation mechanism, the side ends of the radiotherapy platform are provided with two symmetrically-arranged slide rails, and the side ends of the two slide rails are provided with fixed grooves. By arranging the anti-shake mechanism, the influence of body shaking of a patient on the radiotherapy process is avoided, afocus area can be fixed, and normal operation of radiotherapy puncture implantation is guaranteed; by arranging the auxiliary implantation mechanism, the formed blood coagulation thrombus is easier tobreak through in a rotary insertion mode and is also pulled out in a rotary mode, particles are subjected to resistance in an insertion hole diameter, and implanted radioactive particles can be prevented from migrating; and a plurality of radioactive particle sources can be implanted in a single stroke, so that the particle sources are distributed in a fan-shaped umbrella shape relative to a tumor body, the implantation speed is higher, a focus target body can be uniformly irradiated, and the radiotherapy effect is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture and implantation auxiliary device for radiotherapy. Background technique [0002] The puncture implantation of radioactive particles to treat tumors refers to wrapping radioactive isotopes in a titanium tube and sealing them to make a sealed sub-source. The length of the sub-source is equivalent to 4.5mm and the diameter is 0.8mm. The radioactive source is loaded into the sub-source, and then the sub-source is implanted into the tumor with a puncture needle for radiotherapy, in which the doctor's operation and related equipment required for implantation are particularly critical. [0003] However, during the use of the existing puncture implantation equipment for radiotherapy, the following disadvantages are generally found: 1. The puncture implantation process does not require general anesthesia for the patient, so it is difficult for the patient to maintain a...

Problems solved by technology

[0003] However, during the use of the existing puncture implantation equipment for radiotherapy, the following disadvantages are generally found: 1. The puncture implantation process does not require general anesthesia for the patient, so it is difficult for the patient to maintain a static state during the radiotherapy process , causing the doctor to have a certain impact on the puncture operation of the lesion; 2. When the doctor is performing the puncture operation, the needle sheath is directly pierced to the lesion, and bleeding will inevitably occur during the process, and blood will form in a short time after the bleeding. coagulation, and the puncture needle and particle source are relatively thin, the blood coagulation will hinder the implantation of the particle source, and the particles will migrate with the pulling out of the puncture needle after implantation; When emitting particles, only one particle can be implanted at a time, the efficiency is very slow, and the spatial distribution between particles cannot be clearly observed on the display panel through CT and other auxiliary equipment, and if the spatial distribution of the implanted particles is too sparse, If it is too dense, the particles will be wasted, and the adjacent tissues will be damaged after the tumor disappears.
