Embodiment 1

[0043] refer to figure 1 , to make a medical endoscopic laser minimally invasive surgery equipment with controllable energy density.

[0044] The present embodiment adopts pulse laser or continuous laser all can, for example use a DPSSL pulse output infrared laser as laser light source 2, and laser collimation part 4 is made up of a group of two ZnSe meniscus lens lenses, and laser coupling part 5 is made up of single Composed of a zinc selenide meniscus lens, optical fiber 6 is commercially available, 200 microns, SMA905 metal interface, infrared fused silica optical fiber, numerical aperture NA=0.22; medical endoscope adopts German Woolf laparoscopic rigid mirror, cooling system 3 A cooling system combining commercially available high-power semiconductor refrigerating sheets and water cooling is adopted, in which the semiconductor refrigerating sheet directly provides cooling for the laser crystal of the laser and the metal plug-in part of the laser coupling component, and t...

Embodiment 2

[0053] Made according to Example 1, the difference is that the infrared laser light source 2 in Example 1 is replaced by a visible laser light source, a diaphragm is added to the optical path of the laser coupling component, and the laser coupling component 5 is electrically connected to the complete machine control system 11, thereby The aperture is controlled by the control system 11 of the whole machine, which provides an additional degree of freedom for the single pulse energy of the pulsed laser, or the power control during the continuous laser working time; The components 5 are all controlled by the complete machine control system 11 .

Embodiment 3

[0055] Made according to Example 1, the difference is that: replace the infrared laser light source 2 with an ultraviolet laser light source, use a lens to form a laser coupling part to replace the laser coupling part 5 in Example 1, and use a parameter-adjustable cooling system to replace the embodiment. The cooling system 3 in 1 is electrically connected to the overall control system 11 and is controlled by the overall control system 11 to provide an additional degree of freedom for the single pulse energy of the pulsed laser or the power control during the continuous laser working time. The emitting light action distance and orientation control device 8 , the laser light source 2 , the cooling system 3 and the laser coupling component 5 are all controlled by the overall machine control system 11 .

Abstract

The invention relates to a medical endoscope laser minimally invasive surgical device with controllable energy density, comprising that laser generated by the laser light source is coupled into an optical fiber by a laser coupling part, the optical fiber is arranged in a control device for decisive range and position of emergent light, the control device for decisive range and position of emergent light is arranged at the opening of a medical endoscope by an interface part of the medical endoscope and electrically connected with a man-computer I/O system by a whole machine control system, and a power supply supplies power for a whole machine; a cooling system cools the laser source, the man-computer I/O system provides the man-computer interaction function, and the laser coupling part is electrically connected with the whole machine control system; a comprehensive control system can lead the instantaneous energy density of the laser which is acted on the affected site to achieve the preset value by controlling and coordinating the laser source and two parts of the control device for decisive range and position of emergent light.

Description

technical field [0001] The invention relates to a laser medical device for implementing laser minimally invasive surgery; in particular, it relates to a medical endoscope laser minimally invasive surgical equipment with controllable energy density. Background technique [0002] In recent years, lasers have been more and more widely used in the medical field for cutting and vaporizing biological tissues (such as lesions) and non-biological substances (such as surgical sutures), such as literature [1] H.-Peter Berlien, Gerhard J.Müller, H .Breuer, et al. introduced, but many effects and side effects have not yet formed a fixed parameter. Reflected in the specific medical equipment, in the minimally invasive surgery using medical endoscope, the use effect of medical laser equipment is heavily dependent on the personal experience of the operator, such as literature [2] Chen, Mingzhe, The development of laser surgery and medicine In China Proceedings of the SPIE, Volume 5967, pp...
