Particle implantation system and operation method

Abstract

The invention relates to the technical field of medical particle implantation, and discloses a particle implantation system. The particle implantation system comprises CT imaging equipment, a data processing system, a resistive sensor and a laser positioning system; the CT imaging equipment, the resistive sensor and the laser positioning system are all connected with the data processing system. The invention further discloses an operation method of the particle implantation system. By means of the particle implantation system and the operation method, the surgical time is shortened, and the treatment effect is improved; dynamic change data of the needle insertion angle in the process of inserting an implantation needle is obtained by simulating the deviation movement condition of the focuspart and the related tissue of the focus part, the change of the implantation angle of the implantation needle is evaluated in real time in the surgical process, the influence of the directional deviation of the focus part and the related tissue due to extrusion on the accuracy of particle implantation in the puncture process is reduced, and the CT use frequency is reduced; a doctor is guided bylasers in surgery, the surgical operation procedures are simplified, the puncture accuracy is improved, and the repeated puncture rate is reduced.

Description

technical field [0001] The invention relates to the technical field of medical particle implantation, in particular to a particle implantation system and an operation method. Background technique [0002] At present, 70% to 80% of cancer patients are already in the middle and advanced stages when they are diagnosed. Traditional cancer treatment methods, such as radiotherapy and chemotherapy, are limited by dose and other factors, and it is difficult to completely kill tumor cells, and the treatment effect is not ideal. Tumor interventional therapy has the advantages of minimally invasive, low cost, safety, and good curative effect. Especially for those inoperable tumor patients, tumor interventional therapy has increasingly shown its status in tumor treatment. [0003] Percutaneous puncture is a surgical method often used in tumor interventional therapy. It injects drugs or implants radioactive particles or implants magnetic heat seeds into the tumor through a puncture needl...

Problems solved by technology

In the past, doctors usually searched for puncture points based on experience, and directly inserted the puncture needle into the lesion, which was inaccurate and usually required several times to find the lesion. Or during the implantation process of magnetic heat seeds, implantation deviation and uneven implantation will affect the treatment effect

[0004] With the continuous development of medical imaging technology, at present, the puncture point, puncture depth and puncture angle can be determined firstly through the guidance of CT and other imaging equipment, and then the doctor can rely on his experience to hold the puncture needle for tumor puncture. Accuracy and safety, but because the conventional CT scanning equipment is not guided in real time, the doctor will need to repeat the puncture process due to the subjective operation and the direction deviation of the lesion and related tissues due to extrusion during the puncture process, resulting in inaccurate positioning. CT scans and even repeated punctures lead to reduced surgical accuracy, prolonged operation time, and increased repeat puncture rates; there is currently a method of percutaneous puncture treatment of tumors on a regular scale under the guidance of CT or ultrasound scanning equipment, although this method It can improve the accuracy of particle implantation to a certain extent, but in more complex anatomical structures, conventional templates are prone to set-up errors, causing the needle path and particle implantation position during particle implantation to be inconsistent with the plan, reducing the The accuracy of the treatment will reduce the radiation dose of the tumor site and increase the radiation dose received by normal tissues, which will affect the treatment effect and increase complications. In addition, it is generally necessary to pre-fix the template through the fixing device, and then drive the template to move to the patient through the fixing device The site to be implanted has a complex structure and cumbersome operation. Multiple CT scans are still required during the operation to determine whether the direction of the needle is correct.
