A laser medical device

Abstract

The invention provides a laser medical instrument. The laser medical instrument comprises a power supply control system, a first laser device and a laser synthesizer, wherein the power supply control system, the first laser device and the laser synthesizer are connected in sequence. The laser medical instrument further comprises a second laser device, wherein the second laser device is connected with the first laser device in parallel, and laser light emitted by the first laser device and laser light emitted by the second laser device are synthesized into a composite laser beam through the laser synthesizer. According to the laser medical instrument, due to the fact that short-wavelength laser pulses emitted by the first laser device and long-wavelength laser pulses emitted by the second laser device are combined into composite laser pulses, explosion energy of plasma can be increased, and the rock smashing efficiency is improved; due to the fact that the first laser device and the second laser device are controlled through the power supply control module, output of the laser of either the first laser device or the second laser device or composite output of the laser of both the first laser device and the second laser device can be achieved, treatment equipment does not needed to be replaced during operative treatment, switching between the two kinds of laser or composite output can be achieved only by controlling the power supply control module, a doctor can conduct treatment conveniently, and the operation efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to a laser medical equipment. Background technique

[0002] At present, laser medical technology is to irradiate the laser emitted by the laser on the tissue to be treated through the medical optical fiber, and perform lithotripsy or soft tissue cutting treatment through the thermal effect or shock wave generated by the laser. The operation time is short and the wound is small, so it is widely used.

[0003] In the prior art, laser medical equipment consists of a laser and a power supply, and a laser medical equipment can only output one type of laser. The lasers commonly used in medical operations are neodymium laser, holmium laser and thulium laser. Among them, when the neodymium laser is output by the laser for treatment, plasma will be generated near the irradiated tissue, and the plasma will explode and generate shock waves. Shock waves are for hard tissues, such as ...
