And the development of semiconductor laser pumping technology, 2 mu m waveband thulium-doped fiber lasers are developed rapidly.Thulium-doped fiber laser
It due to can provide wavelength in 2 μm or so of long wave laser generation, is close with the absorption peak of water, has and fabulous tissue is cut
It cuts and coagulating effectiveness, can be transmitted with ordinary optic fibre, be ideal surgical laser light source.
In surgical operation, laser generate superlaser, passed out by optical fiber, optical fiber pass through again endoscope into
Enter 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 with
And heat-affected zone it is small the features such as, carry out treatment effectively and safely for patient.Using laser to the portion for needing laser therapy
After the tissue of position is cut, need to excrete the tissue after cutting using tissue pulverizer.But the group that the prior art provides
It knits the complicated for operation and easy of grinder and secondary injury is caused to patient.When being treated using laser, it is difficult to realize to laser
Accurate control, it is more likely that the normal tissue of patient can be injured.Surgical operation is carried out using operation handle in the prior art
When, there are complicated for operation, laser output dose is not easy to control, the problem of be easy to causeing secondary damage.
Existing internal deep laser therapeutic equipment does not have accurate target tissue temperature sensing means, generally requires by art
The operation technique and micro-judgment of person exports energy and time for exposure to control laser, inevitably will lead to target tissue because of office
Portion's heat is accumulative and generates irreversible thermal damage, or damages to neighbouring non-target tissue.
It in existing therapeutic scheme, needs first to be determined lesion region, then photo-thermal is carried out to the lesion region and is controlled
It treats, and the prior art needs two kinds of equipment to operate separately, it is cumbersome, simultaneously as using two kinds of equipment, therefore stability is poor,
Control accuracy is low.
In order to cover all sufferer positions, it will usually it is irradiated to some normal tissues, and hot spot is there are center optical power height,
The low problem of edge optical power.
Diagnosing and treating together as one can be avoided diagnosing and treating from separating single twice by the laser imaging targeting ablation pipe
Solely carry out.
Summary of the invention
A kind of laser fiber shield is disclosed the purpose of the present invention is overcoming the above-mentioned insufficient of the prior art, is being swashed
When light treatment, using shield coverage goal region, can accurate therapeutic purpose position, improve operation safety, more pacify
It is complete reliable, it avoids exempting from high-power output laser and heat injury surrounding tissue, is provided with device for monitoring temperature in shield, passes through
In real time, the temperature change for accurately monitoring target tissue, in conjunction with size, quantity and the pass of position of various treatment parameters and target tissue
System, the output energy and pulse frequency of real-time feedback control semiconductor laser meet the application demand of accurate minimally-invasive treatment.
The specific technical proposal of the invention is: a kind of laser fiber shield, the shield are fabricated from a flexible material, institute
State flexible material and form closing inner chamber, it is described it is interior it is intracavitary be filled with fluid, existed by shield described in intracavitary fluid in controlling
It is unfolded and shrinks to change between two states, the shield expansion is drawn fluid from interior in cone after fluid is filled with inner cavity
The flexible material folds after chamber, and the shield is shunk, the coating of the protection cover inner surface coating reflection laser.
The laser fiber shield is arranged in endoscopic working channel, can be with when the shield is contraction state
It is accommodated in endoscopic working channel completely.
The laser fiber shield further includes fluid channel, and fluid is filled with and extracts out the protection through the fluid channel
Cover inner cavity.
The laser fiber shield is hollow structure, and laser fiber can enter bodily lumen through the hollow structure.
The coating uses organic coating, and the organic coating is preferably fluorine doped acrylic resin.
It includes TiO that the coating, which uses,2、Nb2O5Or Ta2O5Composite material.
The coating uses the titanium dioxide layer doped with transition metal oxide.
It is preferred that temperature sensor is additionally provided in the laser fiber shield, for monitoring the laser fiber protection
Temperature in cover.
It is preferred that the protection cover outer surface is coated with heat-barrier material coating, the heat-proof coating material, which contains, to be had by calcium
Iris or monoclinic structure derived from titanium ore (such as by composition formula A2B2O7The plate perovskite structure of expression) or c-axis/a axis
