Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] A semiconductor laser can easily control its laser pulse waveform and energy directly by controlling the driving current waveform of its laser power supply, and its laser wavelength is generally between 600 and 1500nm. Fiber lasers and solid-state lasers directly pumped by semiconductor lasers, such as 1064nm or 1300nm Nd:YAG or Yb:YAG lasers, can also be realized by controlling the driving current waveform of the laser power supply of their pumped semiconductor lasers. Fiber lasers and solid Nd :YAG or Yb:YAG laser pulse waveform control.

Abstract

The invention discloses a high-hemostatic performance laser scalpel. The high-hemostatic performance laser scalpel uses at least two laser sources, with one laser source as a cutting laser source and the other laser source as a hemostatic laser source; laser pulse waveform output by the hemostatic laser source can be programmably controlled by programmably controlling driving current of the hemostatic laser source so as to achieve the optimal hemostatic effect; output laser of the at least two laser sources can be coupled into a single laser beam outputting device by a laser beam synthesizing unit; laser parameters of the at least two laser sources are independent mutually and adjustable; the cutting laser source can be a pulsed or continuous laser source, the laser pulse waveform of the pulsed cutting laser source can be programmably controlled, and the output of the continuous laser source can be modulated so as to achieve the optimal cutting effect. The laser scalpel with excellent hemostatic performance can also use only one laser source, and achieves the optimal cutting and hemostatic effect at the same time through programmable control over the laser pulse waveform of the laser source.

Description

technical field [0001] The invention belongs to a minimally invasive laser surgery device, which selects a laser source with a specific wavelength, and controls the shape and width of the laser pulse wave programmable, so that the laser pulse energy has a controllable penetration depth to the surgical tissue, and realizes The best hemostasis requirement in clinical operation. The minimally invasive laser surgery equipment has excellent hemostatic performance in minimally invasive surgery, including the controllability of the depth of the hemostatic layer, and also has excellent tissue cutting performance, and at the same time minimizes the adverse effects on surrounding normal tissues. Its cutting and hemostasis The ability to effectively improve the efficiency of surgical treatment. Background technique [0002] The goal of minimally invasive surgery is to use surgical methods to cure patients' diseases with minimal trauma and minimal bleeding. Laser is a special light wa...
