Novel pulse thulium fiber laser medical equipment with intraoperative detection function

Abstract

The invention relates to the field of laser medical equipment, particularly to novel pulse thulium optical fiber laser medical equipment with an intraoperative detection function. According to the invention, the novel pulse thulium optical fiber laser medical equipment has the advantages of simple structure, high stability, laser output in double modes and the like; pulse or continuous laser is output through a switchable pulse / continuous thulium optical fiber laser and enters an optical fiber coupler, wherein pulse mode laser and continuous mode near-infrared laser can be switched and outputafter the pulse or continuous laser enters multimode energy transmission optical fiber in a coupling mode, the continuous laser is used for soft tissue gasification excision and hemostasis of large vessels and venous sinuses, and the pulse laser is used for soft tissue cutting so as to meet operation requirements, so that one machine has two purposes, and burdens of hospitals are greatly reduced.

Description

technical field [0001] The invention relates to the field of laser medical equipment, and relates to a novel pulsed thulium fiber optic laser medical equipment with an intraoperative detection function. Background technique [0002] In recent years, the application of laser technology in the medical field has developed rapidly. In the field of soft tissue, laser will soon replace electrocution and become the gold standard of treatment. Less blood loss, no risk of wound infection, no obturator reaction and other characteristics make laser soft tissue surgery gradually win the competition. [0003] High-power lasers with a wavelength of 2um, such as 100W Ho:YAG holmium laser and 120W Tm:YAG laser, also have certain competitiveness in the application of benign prostatic hyperplasia surgery. It is mainly absorbed by water in the tissue, and the high absorption rate leads to shallow tissue penetration, poor hemostasis, and strong tissue resection effect, but poor coagulation and...

Problems solved by technology

However, the holmium laser lithotripsy has strong blasting power, and the impact and displacement of stones are serious. The time for doctors to find stones during the operation greatly delays the overall operation time.

In addition, the tissue temperature is uncontrollable during the process of holmium laser lithotripsy, which is equivalent to the state of blind typing, resulting in a high proportion of thermal injury to the ureter

Continuous 2um laser has some attempts in the field of lithotripsy, but the efficiency of lithotripsy is low and the surgical effect cannot be achieved
