A puncture implantation auxiliary device for radiotherapy

Abstract

The invention discloses a puncture implantation auxiliary device for radiotherapy, which relates to the technical field of medical equipment, and includes a radiotherapy platform, which is also provided with an anti-shake mechanism and an auxiliary implantation mechanism, and two side ends of the radiotherapy platform are installed. There are two symmetrically arranged slide rails, and the side ends of the two slide rails are provided with fixing grooves. The present invention avoids the impact of the patient's body shaking on the radiotherapy process by setting an anti-shake mechanism, and can fix the lesion area to ensure the normal progress of radiotherapy puncture implantation; by setting an auxiliary implant mechanism, the way of rotating and inserting makes the formed The thrombus is easier to get through, and it is also pulled out in a rotating manner. The particles are resisted in the insertion aperture, which can prevent the migration of the radioactive particles after implantation; the radioactive particle source can be implanted in multiple roots in a single stroke, making the particle source Compared with the fan-shaped umbrella distribution of the tumor body, the implantation speed is faster, and the target body of the lesion can be irradiated evenly, 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.
