Description
Technical field
The present invention relates to area of medical devices, and in particular to a kind of replaceable laser probe of the end with optothermal material and
Device for laser therapy.
Background technique
Laser is because of extraordinary cutting power, good coagulating effectiveness and lesser thermal damage, in surgical field
It gets the attention.The high energy pulse laser that laser generates, is passed out by optical fiber, and optical fiber is entered by endoscope again
Human body, by the incoming position for needing laser therapy of the energy of laser, using the high energy, collimation, action time of laser it is short and
The features such as heat-affected zone is small carries out treatment effectively and safely for patient.Laser is doctor to the interaction of bio-tissue
The physical basis of application is learned, the fuel factor of laser is medically to imitate using the laser tissue being most recognized extensively and earliest
One of answer.Laser light incident bio-tissue, within the scope of light penetration depth, absorbed luminous energy is converted into heat.When heating speed
Needed for degree (thermal energy comes from laser irradiation, related with laser intensity and two factors of tissue absorption coefficient) significantly larger than evaporation tissue
The speed of heat, then tissue is by vaporization quickly.
The laser of the exportable 1.65~2.1um wavelength of thulium-doped fiber laser is widest in all rare earth ions, phase
For solid state laser, have that structure is simple, high-efficient, heat dissipation characteristics are good, narrow linewidth, quality for outputting laser beam height etc. are excellent
Point, thus the thulium optical fiber laser of high peak power pulse output had obtained extensive research in recent years.But thulium is mixed near 2 μm
Optical fiber laser the operations such as is cut to tissue, is gasified and needing biggish pulse energy, and laser power is mainly by mixing thulium
Fibre core provides.But with the significant reinforcement for mixing optical power density in thulium gain fibre, it may appear that serious fuel factor causes thermotropic
Phenomena such as birefringent, phase distortion, hot focus, thermal lens, seriously affects the output power and beam quality of laser, becomes limitation
The lethal factor that laser performance improves.
The Chinese invention patent of Publication No. CN104638506A discloses 1.9 microns of high-power prostate laser of one kind and controls
Instrument is treated, the compensation of different modes can be carried out for different operation power, solves thulium-doped fiber laser to increase power
And there is the problems such as efficiency decline and beam quality variation.But this scheme still can not solve the problems, such as the fuel factor of optical fiber.
CN107412957A discloses a kind of photo-thermal therapy probe based on photo-thermal nano material comprising closed at one end
Cylinder-like shell, the photo-thermal nano material for being filled in interior of shell closed end kill tumour and other diseases by implementing high temperature
Become histocyte.But this scheme is implemented to treat only with high temperature, and it closes nano material inside the shell, knot
Structure is complicated, heat production low efficiency.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of end and controls with the replaceable laser probe and laser of optothermal material
Device is treated, optothermal material, the optothermal material covering part fiber end face, in this way, light are arranged by the fiber end face in cutter head
The efficient photothermal conversion of hot material improves the Thermogenesis of probe, improves fiber optic temperature, but does not influence the output of laser, improves
Temperature, then contact surgical operation is carried out, acting on tissue makes procedure efficiency significantly simultaneously for the high temperature and laser of cutter head tip
It improves, required laser power is many compared to the decline of traditional fiber non-contact method, reduces the hair of optical fiber fuel factor problem
It is raw, and the laser probe is changeable type structure, after first use, replaces cutter head, does not have to replacement operation optical fiber, greatly
Save consuming cost.
