Technical field
The present invention relates to laser therapy fields, and in particular to a kind of optical-fiber laser therapeutic device that laser probe is replaceable.
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.Exportable 1.65~the 2.1um of thulium-doped fiber laser
The laser of wavelength, be it is widest in all rare earth ions, for opposite solid state laser, have structure simple, high-efficient, scattered
The advantages that thermal characteristics is good, narrow linewidth, high quality for outputting laser beam, thus the thulium optical fiber laser of high peak power pulse output
Extensive research had been obtained in recent years.
Laser is the physical basis of medical application to the interaction of bio-tissue, and the fuel factor of laser is medically to make
With one of the laser tissue effect being most recognized extensively and earliest.Laser light incident bio-tissue, in light penetration depth
In range, absorbed luminous energy is converted into heat.When (thermal energy comes from laser irradiation to heating speed, inhales with laser intensity and tissue
Receive two factors of coefficient in relation to) significantly larger than evaporate tissue institute calorific requirement speed, then tissue by vaporization quickly.
Laser probe has contact and two kinds contactless, relatively common for contactless cutter head, such as Publication No.
The patent document of CN204814176U discloses a kind of optical-fiber laser scalpel, and the emergent light that laser fiber issues passes through transmission
Window irradiates destination organization, but this cutter head is single in the presence of outgoing light direction, can not go deep into the problem of narrow positions is treated, connect
The cutter head of touch can be contacted in treatment with tissue, and can pollute service aisle in use, be caused logical comprising work
The endoscope in road can only be intended for single use or need to carry out complicated cleaning and sterilizing process.
Summary of the invention
To solve the above problems, the present invention provides a kind of optical-fiber laser therapeutic device that laser probe is replaceable, the knife
Head can removably be connected with laser conduction optical fiber, and when being treated, the cutter head can stretch out service aisle, the cutter head
With sheath, pollution when can prevent treatment to service aisle, after use, can only replacement cutter head, it is expensive in peep
Mirror part may be implemented to reuse.
Technical solution of the present invention is as follows:
A kind of optical-fiber laser therapeutic device that laser probe is replaceable, described device include endoscope, laser conduction optical fiber,
Laser probe is provided with service aisle in the endoscope, and the laser conduction optical fiber is arranged in the service aisle, described
Laser probe can removably be connected with laser conduction optical fiber, and the laser conduction optical fiber can move in service aisle,
Sheath of the laser probe with covering service aisle.
The laser probe is connected through a screw thread with laser conduction optical fiber or blocks and connect.
The sheath covers service aisle, can prevent steam from entering service aisle, prevent the pollution to service aisle.
The sheath is made of elastic material, it is preferred to use rubber material is made.
The service aisle edge protrusion endoscope tip plane certain length is used for the fixation of the sheath.
Optionally, the service aisle bordered profiles circularize the fixation that recess is used for the sheath.
The laser conduction optical fiber can be axially moveable in service aisle, and the service aisle front end is provided with and swashs
Light conducts the bayonet of optical fiber cooperation, and the bayonet includes the elastic brake lining for closing bayonet, and bayonet outer is provided with control brake lining
Switch, open brake lining, the laser conduction optical fiber can stretch out bayonet, connect with the cutter head, after treatment end, to described
Cutter head and the sheath are cleaned, and the connection of the cutter head Yu laser conduction optical fiber is released, and the laser conduction optical fiber is received
Bayonet is returned, brake lining rebounds automatically, bayonet is closed, then release being fixedly connected for the sheath and service aisle, in this way, primary operation
Later, disinfection only need to be purged to external tothe endoscope, without carrying out cleaning and sterilizing to endoscopic working channel.
The shape of the brake lining can according to need setting, can be two semicircle brake linings, or multiple triangles
Blade.
Compared with prior art, the beneficial effects of the present invention are:
1, valve replacement cutter head is only needed after the laser therapy operation of a patient, other components can repeat to make
With, reduce operation consumptive material loss, and after use without to endoscopic working channel carry out cleaning and sterilizing, greatly simplify
Cleaning and sterilizing step.
2, cutter head can freely stretch out service aisle, expand working range, can not be by the limit of endoscope diameter size
System, can be applicable in narrow positions, may be implemented 360 degree without dead angle working range by the cooperation with laser probe.
3, can free switching different laser probe as needed, for example need the position of direct projection using direct projection cutter head,
The position for needing side to penetrate can select side to penetrate cutter head.
