Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a tumor radioactive particle chain manufacturing and injecting device.
Background
Radioactive particle implantation is one of the important methods for tumor intervention. Interventional therapy is a minimally invasive therapy carried out by utilizing modern high-tech technology, and is characterized in that under the guidance of medical image equipment, special precise instruments such as catheters/guide wires and the like are introduced into a human body to diagnose and locally treat in-vivo pathological changes. The digital imaging technology is applied in interventional therapy, so that the visual field of a doctor is expanded; the physician's hands are extended by the catheter/guidewire and many diseases that were previously untreatable/necessitated by surgical or medical treatment may be treated with poor efficacy. Currently, interventional therapy has become one of the main means of clinical treatment in modern hospitals, and will become one of the most promising clinical medicine specialties in the 21 st century. The radioactive particle implantation treatment technology is a technology for implanting radioactive particles into a tumor and treating the tumor by continuous and short-distance radioactive rays emitted by a radioactive source. However, the particles used in clinical practice in China are basically monomer structures, and in the operation, due to the special local anatomical structure of a patient and the limitation of the operation level of an operator, the single particles are difficult to be kept to be arranged in a straight line at equal intervals according to the requirements of the preoperative plan. Often resulting in particles that are agglomerated or spaced too far apart, resulting in uneven particle dose distribution. In order to meet the requirements of preoperative planning, the implantation of the particles is needed in the area with insufficient dosage, so that the implantation quantity of the particles is increased, the economic burden of a patient is increased, and the complication rate is increased. Also, migration and migration often occur when individual particles are implanted. The migration of the radioactive particles may cause serious complications such as embolism to heart, lung, cerebral vessels, etc., which is not good for the physical and mental health of the patient. The problem of migration of radioactive particles is serious and needs to be solved urgently.
