Abstract
A kind of optical fiber suitable for middle Infrared Therapy laser can meet safe handling in the intracorporal requirement of people, can transmit the laser of middle infrared wavelength, for various treatments, operation purpose.
Description
Technical field
It is used for transmission the medical optical fiber of mid-infrared laser, this kind of medical optical fiber can be used safely in control into the intracorporal laser of people
It treats and performs the operation.
Background technique
Laser irradiation to required diagnosis in vitro or in vivo is treated operative site by clinical application.
The output end of laser fiber can be made into various shape as needed, if dome shape is with the laser-beam divergence angle to transmitting
Certain adjustment is done, so that laser is to certain lateral transmitting, taper or wedge shape enter so as to optical fiber into soft tissue inclined plane shape
Deng.
Existing general silica quartz optical fiber has good light transmission to 1.06 microns or less even 300 nanometers of ultraviolet light
Property, and there is sufficiently high damage threshold.If doing special control to fibre core manufacturing process, to reduce the 0H in optical fiber quartz material
Root concentration, optical fiber can have the translucency of enough satisfaction near 2 mum laser wavelength.
Silica quartz optical fiber material chemical characteristic is stable, nontoxic, strong to tissue safety, photodamage resistant, again
There are sufficient mechanical strength and flexibility, is suitable for various into the intracorporal operation application of people.It is widely used to various external and bodies
Interior laser therapy and operation, such as the excision of laser beautifying, various hard and soft tissues, urinary system and liver and gallbladder system rubble, orthopaedics application.
But silica quartz optical fiber sharply increases the transmission attenuation of mid-infrared light that wavelength is more than 2.2 microns,
It is up to every meter 70% or more for the decaying at 3 microns in wavelength, can not be applied to transmission wavelength is more than 2.2 microns
Mid-infrared laser is made medical treatment and is used.
Research and develop has the optical fiber of lower attenuation rate is always a to have much challenge in the middle infrared band that wavelength is more than 2.2 microns
Project.So far more mature and can do and industrial mainly have the referred to as fluoride of ZBLAN.It has in 3 micron wave lengths
There is higher transmission transmitance, such as every meter 80% or more.But a serious problems of this material are that it cannot directly be answered
Medical operating for entering human body is treated, because these materials are considered having tissue injury or toxic.
Helplessly, be more than 2.2 microns of mid-infrared laser for wavelength, be used as medical treatment in use, can only using 4 to
The joint arm that 5 optical reflection joints are constituted is as the laser transmission apparatus with certain dynamic role.This joint arm laser
Defeated loss depends primarily on the laser total reflection specular reflectivity in (optical reflection joint) at each joint arm rotation point, entirely
Optical path cavity size and laser beam size in the optical path Adjustment precision and joint arm of joint arm.Realize final entire joint arm
Laser efficiency of transmission be more than 90% or more, not difficult matter in practice.But disadvantage is that this joint arm is not agile enough, uses
Inconvenience, the more limitation because of its volume and structure, and be not used to enter in human body and carry out various mid-infrared laser operations or control
It treats.
Summary of the invention
Being used for transmission the medical optical fiber of mid-infrared laser, especially this kind of medical optical fiber can be used safely in enter in human body
Laser therapy and operation.
Detailed description of the invention
A kind of used laser medicine laser fiber of Fig. 1
Infrared medical optical fiber in Fig. 2 present invention
Specific embodiment
Fig. 1 is the existing medical optical fiber schematic diagram generally used.Wherein 01 be optical fiber light passing fibre core, for lower than 2.2 micro-
The near-infrared or visible light and near ultraviolet optical maser wavelength of rice, common material are quartzy (silica).02 is the sheath of optical fiber,
It is generally produced from plastic material, the selection of plastic material will consider its mechanical strength, flexibility and should directly can answer safely
For inside of human body, typical material is polytetrafluoroethylene (PTFE) (Teflon) or other polyester materials.03 denotes the end of optical fiber
Position, fibre core 01 expose that sheath is a bit of, and length is in several millimeters or so.It is generally cut by special the end of fiber core 01
The tool of cutting is cut into illustrative right angle plane.It the end face of fiber core 01 also can be with fibre core at the plane of a fixed inclination.
Fig. 2 is to be longer than the medical optical fiber schematic diagram of 2.2 microns of mid-infrared laser for wavelength in the present invention, 21 in figure
For the fiber cores that with transmission wavelength can be more than 2.2 mum lasers, such as aforementioned LAZBN fluoride.22 is can be by that can enter safely
The material of human body application, the optical fiber jacket as made of polytetrafluoroethylene material.23 be laser output head, by infrared in corresponding
Optical maser wavelength substantially transparent, and can security application be made in the intracorporal optical material of people, such as undoped YAG crystal, Lan Bao
Stone etc..Since the length of the output end is very short, within the scope of several millimeters, even if output tip materials are to more than 2.2 microns
Middle infrared wavelength laser-light transparent degree is not high and certain laser energy is caused to lose, if the loss is no more than 10% or more, still may be used
To receive.
The inner surface 26 of output end 23 is processed into optical flat, and outer surface 27 can be processed into and in a vertical angle flat of axis
Face or other inclined-planes or curved surface, to adapt to the needs of different operation applications.The output end face 25 of fibre core 21 is processed into and fibre core axis
Line plane at right angle, and directly contacted with the inner surface 26 of end 23.
24 be the sealing fixture made of transparent or opaque material, is used for optical fiber output end 23 and fiber cores
21, the sealing fastening of optical fiber jacket 22.Transparent material sealing fixture such as fused quartz tube.Opaque material sealing fixture is not if
Become rusty steel pipe.It is a kind of sealing fastening concrete operation method be slightly to be heated to this sealing fastener 24, enable it slightly expand, by light
Fine and output end cooperate insertion 24 as shown in Figure 2, after 24 cool back room temperature, it with export end 23 and optical fiber jacket 22
Form fit sealing.It can also be squeezed to 24 in circumferencial direction after it will export end 23 and optical fiber 22 includes sealing fastener 24
Pressure.Make to form reliable fit sealing between sealing shroud 24 and optical fiber jacket 22 and output end 23.It also can be in sealing shroud 24 and defeated
A plastic bushing (not shown) is added between the seal area of end 23 out, relies on its flexibility and increases the reliable of sealing fastening
Property.This plastic bushing can be made of material identical with fiber boot 22.
The diameter of fiber cores 21 can be between 150 to 800 microns (i.e. 0.15 to 0.8 millimeters).Outside optical fiber jacket 22
Diameter is between 0.5 to 1.5 millimeter.
The diameter of fit sealing part 24 depends on the outer diameter of optical fiber set 22, such as 1 to 1.5 millimeter or so.
The thickness of pipe wall of sealing element 24 can be 0.1 to 0.5 millimeter, and length can be between 10 to 20 millimeters.
Optical fiber component shown in figure two not only effectively can be more than 2.2 microns of mid-infrared laser by transmission wavelength, but also because own
Exposed material is the material to tissue safety, therefore can be used safely in enter the intracorporal laser surgey of people and treatment.
