With laser surgery knife, there is extraordinary development prospect.
At present in clinic, the semiconductor laser of 810-980nm is more common in the department of stomatology, dermatology, but in reality
Find that actual ablation cutting effect is not high in use process, because the soft tissue absorbed rate in near-infrared wavelength region compares
Low, photo-thermal effect is unobvious, and the cutting efficiency for frequently resulting in soft tissue is not high, and surgeon increases because cutting efficiency is low sometimes
Often there is normal soft tissue thermal damage in semiconductor output power, to recovery makes troubles more afterwards.
The method for the fiber tip activation being recently proposed, can make a part of laser energy in fiber tip photothermal conversion
Thermal energy improves fiber optic temperature, then row optical Fiber Contact surgical operation, fiber tip high temperature and laser action are in the dual work of tissue
With greatly improving procedure efficiency.Laser power needed for after activating simultaneously declines very compared to traditional fiber non-contact method
It is more, the case where reducing thermal damage generation.Pertinent literature " grind by optical fiber activation of the semiconductor laser in oral soft tissue operation
Study carefully " although having been reported that those skilled in the art can not know how by the document of the abstract property to optical fiber activation
Carry out optical fiber activation.

Specific embodiment
Technical solutions of the utility model are described in further detail in the following with reference to the drawings and specific embodiments, it is described
Specific embodiment is only explained the utility model, is not intended to limit the utility model.
As shown in Figure 1, the utility model proposes a kind of optical fiber activate device, including a canister 1 and with it is to be activated
The laser 3 of 2 one end of optical fiber connection and the handle 4 that 2 other end of optical fiber to be activated is set, the material of the canister 1
Matter is medical metal material resistant to high temperature, and the volume of the canister 1 is preferably sized as that one hand is suitble to hold for operating easily,
The metal can held.The optical fiber activating substance 5 of compacting is loaded in the canister 1, the optical fiber activating substance is pharmaceutical grade
The carbon containing material of height, the form of the carbon containing material of height is powdered or graininess, and activating substance is laid in after compression
Mode in canister 1 includes: that the section shape of the evenly laid out i.e. described optical fiber activating substance 5 in a thickness direction is square
Shape, as shown in Figure 2；Or inclined surface laying, i.e., the section shape of the described optical fiber activating substance 5 in a thickness direction are right angle ladder
Shape, as shown in Figure 3.
It is as follows that the step of activating for the optical fiber of laser surgery is carried out using the optical fiber activation device of the utility model:
Two hand of step 1) holds canister 1 and handle 4 respectively, stablizes after holding, to be activated by connecting with laser 3
Optical fiber 2 is perpendicularly inserted in canister 1, and the tip of optical fiber 2 to be activated is made to contact the optical fiber activation in the canister 1
Substance 5；
Step 2) opens the laser 3, and laser output power is controlled in 0.5W-1.0W, continues 1~2 second, completes light
Fine activation.As shown in figure 5, the optical fiber 21 after above-mentioned activation processing, it is 100-400 μm carbon containing that tip, which has diameter,
Microvesicle 7, the feasible laser surgery of optical fiber 21 after activation.
The principle that optical fiber activation is carried out using the optical fiber activation device of the utility model is that laser fiber contact action is in containing
When carbon material, low-power energy 0.5-1W output under, carbon lighted by laser after at fiber tip fierceness burn, melting fiber
Material, and the microvesicle that a large amount of diameters are 100-400 μm is formd in fiber tip, microexamination is micro- to there is amorphous carbon to be filled with
Chamber is steeped, Fig. 5 shows the microstructure of the fiber tip after activation；Amorphous carbon in microvesicle can absorb laser and generate
Heat, carbon containing microvesicle quantity and density determine absorb laser number.
The canister 1 is equipped with container cover 6, and container cover 6 is opened when carrying out optical fiber activation, is closed after activation
Lid, protects activating substance 5 not polluted by other substances in environment.
If activating substance 5 be not stack pile uniformly be layered on 1 bottom surface of canister be in inclined-plane be laid with activating substance
5, the tread distribution of the another side thin (with a thickness of H1) in side thick (with a thickness of H2) is formed, as described in Figure 3.In activation, selection activation
The different-thickness of substance 5 can make optical fiber when activating at optical fiber end to control the activation degree of optical fiber if the site that selection is thicker
The tip forms the carbon containing microvesicle of more crypto set, i.e., so that including more amorphous carbon in all microvesicles, forms deep activation, make
Fiber tip forms bigger, the more carbon containing microvesicle of density after activation, absorbs more laser.The distribution of activating substance tread
Keep activation degree more flexible, the more activation selections of the offer according to needed for clinical temperature.
Although the utility model is described above in conjunction with attached drawing, the utility model is not limited to above-mentioned
Specific embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the ordinary skill of this field
Personnel are under the enlightenment of the utility model, in the case where not departing from the utility model aims, can also make many variations, this
It belongs within the protection of the utility model a bit.
