Tumor laser thermotherapy and multi-parameter real-time monitoring probe

Abstract

The invention discloses a tumor laser thermotherapy and multi-parameter real-time monitoring probe, which comprises a contact probe main body, wherein the contact probe main body comprises a rigid shell, a laser emitting optical fiber and a plurality of near infrared double optical fibers which are inserted in the rigid shell, a temperature sensor and a colloid hose; a main cavity for allowing thelaser emitting optical fiber to pass through and sub cavities which are distributed around the main cavity are formed in the rigid shell; the plurality of near infrared double optical fibers are inserted in the other sub cavities in the shell, with inserting depths in a mode of being gradually decreased in a circumferential direction, and two adjacent optical fibers keep a consistent inserting depth difference therebetween; the end of each near infrared double optical fiber is an inclined plane of 45 degrees, and the side face, facing to the inclined plane of the end, of the shell is providedwith a window; a light-transmitting plate is embedded in the window; and the colloid hose is embedded in a groove in the tail of the rigid shell, and the colloid hose is used for wrapping a signal line, the laser emitting optical fiber and the near infrared double optical fibers. The probe provided by the invention, when implementing laser thermotherapy, can achieve real-time monitoring on multi-parameter indicators in a tumor tissue.

Description

technical field [0001] The invention belongs to the field of interventional medical systems, and in particular relates to a tumor laser hyperthermia and multi-parameter real-time monitoring probe. Background technique [0002] Tumor hyperthermia has developed rapidly in recent years and has become another important tumor treatment method after surgery, radiotherapy, chemotherapy and biological therapy. At present, a large number of in vitro experiments and clinical data show that although tumor hyperthermia cannot replace surgery, chemotherapy or radiotherapy as an independent tumor treatment plan, it has obvious synergistic and complementary effects on chemotherapy, radiotherapy and surgery. . Laser hyperthermia is a tumor hyperthermia technology that can cause coagulation and necrosis of local biological tissues when heated. Compared with traditional surgery, laser hyperthermia is a minimally invasive method, which rarely occurs a large amount of bleeding and has high saf...

AI Technical Summary

Problems solved by technology

[0005] At present, clinically, there is a lack of instruments that have the functions of laser hyperthermia, temperature detection, and hyperthermia effect evaluation at the same time, so that in the laser hyperthermia surgery of tumors, doctors use subjective and experience to judge the patient's condition, and cannot scientifically and effectively guide surgery, Assessing treatment effects, often resulting in suboptimal treatment outcomes

[0006] At the same time, in tumor hyperthermia surgery, due to the lack of multiple parameter measurement systems, there is no evaluation method for limited parameters, and there is no standardized data acquisition and storage specification

The series of data collected lacks a unified storage standard and cannot be analyzed and identified in the future
