Problems solved by technology

[0006] Traditional laser lipolysis uses a single laser, and the optical fiber used is a flat-ended optical fiber. The laser output of this optical fiber is linear and non-diffusion. The local temperature may be too high, and the slight deviation of the laser light angle may cause skin burns and other defects.

Abstract

The invention discloses a laser treatment system for tissue ablation, which includes a medical switch device, a human-computer interaction display device, a main control device, a medical semiconductor laser drive module, a medical semiconductor laser module, a medical semiconductor laser temperature control device, and a cooling device 1 , cooling device 2, optical fiber connectors and optical fiber components for minimally invasive surgery. The medical semiconductor laser module includes a first laser component and a second laser component; the wavelengths of the first laser and the second laser are different; the first laser is a visible wavelength laser used to indicate the irradiation area, and the The second laser is an eye-safe infrared wavelength laser for fat melting, which has a higher absorption rate of water and fat.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a laser treatment system for tissue ablation, which is used for safe ablation of human body fat layer. Background technique [0002] With the continuous improvement of people's living standards, changes in diet structure, and high-pressure fast-paced life, more and more people are plagued by obesity problems, and the weight loss market is becoming larger and larger. People continue to study and explore various micro Create a method for losing weight and melting fat. At present, the methods of minimally invasive fat-melting and weight loss mainly include injection fat-melting, ultrasonic fat-melting, and traditional laser fat-melting. [0003] The principle of injection fat-dissolving weight loss treatment is based on mesoderm treatment. The liquid containing weight loss ingredients is injected directly into the subcutaneous fat layer of the human body in the form o...
