Device for cancer surgery fluorescence guiding and residual cancer tracing and clearing

Abstract

The invention provides a device for cancer surgery fluorescence guiding and residual cancer tracing and clearing. The device is formed by combination of a host, an image lighting and acquiring unit and a photodynamics therapy irradiator, wherein the host is provided with a program controller, a fluorescence-reflected light image processor, an image displayer and an image lighting and therapy lighting source. Surgical navigation can be conducted after a proper amount of target nanometer photosensitizer is injected into the body of a patient, residual cancer tracing is conducted in surgery, and key information is provided for precise treatment of cancer patients. Peripheral occult cancer and residual cancer in blood can be detected, tumor cells are killed selectively, photodynamics therapy which hardly causes damage to healthy tissue is adopted, and residual cancer is eradicated. In this way, radiotherapy and chemotherapy quite harmful to health do not need to be adopted to prevent canceration, recurrence and metastasis after cancer surgery treatment, the survival rate of cancer patients can be increased greatly, and the living quality of cancer patients in the recovery period can be improved greatly.

Description

Technical field: [0001] The invention belongs to the technical field of medical instruments, and relates to a device for fluorescent navigation in cancer surgery and residual cancer tracing and removal technical background: [0002] It is not an exaggeration to talk about the color change of cancer to describe that cancer, which has become the number one killer of human beings, is so rampant and unscrupulous. The latest global statistics collected by the World Health Organization show that there are 14 million new cancer cases every year in the world. It is reported that 22% of cancer patients in the world are now Chinese, and the number of new cancer patients in China is 3.07 million. The prediction data 20 years later is even worse, and the global cancer patients will increase by 70%, which indicates that the era of "tumor is fiercer than tiger" is coming. [0003] my country also spends nearly 100 billion on cancer treatment every year, but it still has little effect. T...

Problems solved by technology

[0004] This tragic situation is due to the lack of effective treatment methods in cancer treatment. It is difficult to find residual cancer in cancer surgery, and it is even more difficult to remove cancer cells that enter the blood circulation, causing cancer recurrence and metastasis; The use of radiotherapy and chemotherapy can cause great harm to the body, the defense ability of the immune system is greatly reduced or even completely collapsed, and a small infection or complication is enough to kill a cancer patient. These factors are caused by many factors, and the excessive damage during the treatment is even more obvious. How feeble are today's treatments
