Low-energy photon brachytherapy system with robot

Abstract

The invention belongs to a low-energy photon brachytherapy system with robot in the medical equipment field. The low-energy photon brachytherapy system comprises an imaging system, a six-degree-of-freedom robot treatment bed, a six-degree-of-freedom surgery robot and a planning software system. The imaging system is a C-arm imaging system or / and a non-X-ray source detector system. The six-degree-of-freedom robot treatment bed is formed by connection of a treatment bed support arm and a bed surface. The six-degree-of-freedom surgery robot consists of a surgical robotic mobile device, a surgical robotic arm, a low-energy photon ray source and a source adapter that are connected successively. According to the low-energy photon brachytherapy system provided by the invention, defects that a dosage cold point exists in existing brachytherapy and the applicability of the therapeutic equipment is low can be overcome. With the brachytherapy system, the treatment dosage design can be optimized; irradiation becomes accurate; dosage cold points are eliminated; the operation becomes simple; and the safety and reliability are high. The low-energy photon brachytherapy system is suitable for clinic treatment of tumors of primary hospitals.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a robot low-energy photon brachytherapy system. Background technique [0002] Brachytherapy has a history of more than 50 years in my country. In the past, it was mainly used for the treatment of gynecological tumors. The use of radiation sources and treatment machines was relatively simple, and the technology was relatively backward. In recent years, with the continuous increase in the variety of radioactive sources, the rapid development of computer and mechatronics technology, and the continuous improvement of the radiotherapy planning system, the scope of brachytherapy in my country has expanded to the treatment of various tumors in the whole body: such as nasal Pharyngeal cancer, various oral cancers, esophageal cancer, prostate cancer, rectal cancer, lung cancer, bronchial cancer, bile duct cancer, pancreatic cancer, and vascular interventional therapy, etc. The disadvantag...

AI Technical Summary

Problems solved by technology

The disadvantage of traditional brachytherapy is that the dose "cold spot" caused by the rapid decrease of the dose outside the treatment target area and the imprecise design can lead to a rapid decline in the possibility of clearing tumor cells

Similar to other treatments, loss of a region within the tumor or significant underdosing of an area can lead to failure of the entire curative therapy

Moreover, the treatment equipment is complicated and expensive, and it is not suitable for clinical use in general hospitals at all levels (especially those hospitals without radiotherapy specialties)
