Description
The present invention relates to a kind of electrosurgical equipment.
Laser is the effects of poly-light and heat two big main effects to organism in medically maximum contribution, and these two kinds of effects especially have unique effect in tumor diagnosis and treatment field.Clinically, because laser has good monochromaticity, can utilize the visible laser of certain wavelength, cooperate hematoporphyrin derivative (HPD) to come the diagnosis and treatment tumor, this is that any light source is incomparable.Utilize the heat effect of laser, can be used for the gasification cutting and eliminate tumor or thermocoagulation and heat kill destruction tumor.Because laser is to different biological molecules content and the selective absorption effect of tissue characteristics, this is that any thermal source institute can not reach.Experiment shows: tumor cell DNA (ribonucleic acid) content is higher than normal cell, easily absorbs iraser and living heat.YAG laser is easily absorbed by the tissue of dark color, clinically can be tumor staining, and favourable focus absorbs laser and gives birth to heat, reaches the purpose of selective destruction tumor.The heat effect of laser is removed with outside the Pass different biological properties have, and with being subjected to the laser energy according to the district direct relation is arranged also.Clinically, utilize high power laser light gasifiable (containing carbonization) to eliminate tumor; Utilize the laser of middle low power, but thermocoagulation or heat kill destroy tumor.On the macroscopic view, under equal conditions, the gasification of laser (containing carbonization), thermocoagulation, heat kill are with a branch of laser different-energy (power density).Laser to target area biological tissue heat effect degree be by local temperature change determine that in general, the laser gasification temperature is more than 1000 ℃; Heat freezing temperature is 60～100 ℃; The heat kill temperature is 43～45 ℃.These provide the foundation of science for clinical laser therapy.
Because conventional planar optical fiber emission laser is more concentrated, open up contactlessly, and can not cooperate with the intracavity corresponding organ, under scope, to operate, the activity owing to organ makes the optical fiber emitted laser be difficult to aim at focus.Do not have measuring device simultaneously, make clinical high power applications complication big.Be difficult to grasp the effect degree of laser, can not thoroughly destroy focus, give clinical many unfavorable factors of bringing, do not reach the curative effect of expection the target area tissue.
The applicant discloses a kind of can the raising and has been subjected to shine the power density of distinguishing in the CN1133706A patent application, reach the dual photothermal laser probe of controlling the cancer effect of light power and high temperature, the shell that it adopts light transmissive material to make, shell is cylindrical, the sealing of one end, the opening socket probe handle of shell is established central canal at probe handle central shaft; One end of optical fiber passes the sealed end inboard that central canal place shell; One end of thermocouple wire passes the inwall that central canal place shell; Water inlet pipe and water outlet pipe is arranged in the central canal, the sealed at both ends of handle and central canal of popping one's head in, probe handle inside is hollow-core construction.
It is high temperature resistant that purpose of the present invention aims to provide a kind of improved energy, light, and light-permeable is difficult for fragmentation, can join the contact laser photo-thermal conversion probe apparatus of scope; Both can keep the biological effect characteristic of former optical maser wavelength to the target area tissue, can be transform light energy heat energy again, by thermometric focus carried out accurate treatment, efficient, safety.
The present invention includes probe, probe fixed handle, thermal detector, optical fiber, be provided with spring metal pipe and fixture thereof.
That probe adopts is high temperature resistant, bright, light-permeable, not easily broken material (for example quartz, gem etc.) are made.The probe outer rim is equipped with one or more thermal detector, for example thermocouple temperature measurement device, quasiconductor thermal detector, infrared temperature measurement device etc., thermal detector places probe middle part outer rim, the thermal detector transmission line is drawn from the probe stiff end by the thermal detector transmission line passage of being located in the probe, at probe stiff end central part one optical fiber duct is arranged.The probe fixed handle is made up of probe hold-down nut and probe fixed screw, end at the probe hold-down nut is established the probe fixed card slot, probe fixed screw and probe hold-down nut are spirally connected, optical fiber and thermal detector transmission conduit are established in middle part at the probe fixed screw, so that pass optical fiber and thermal detector transmission line, optical fiber and thermal detector transmission conduit are established bayonet socket away from an end of probe, so that fixed fiber and thermal detector transmission line; The central authorities of fixed screw away from probe one end establish holddown groove popping one's head in.The spring metal pipe passes fixing card of spring metal pipe and spring metal fixed screw, one end of the fixing card of spring metal is socketed on the holddown groove of probe fixed screw, and spring metal pipe fixed screw is socketed on the fixing card of spring metal pipe and is bolted in the holddown groove of probe fixed screw.One of optical fiber is terminated at the optical fiber duct of probe, and the other end is external in laser instrument.
Said optical fiber duct bottom is arcs of recesses, helps laser in the probe even dispersion.The probe with the probe hold-down nut contact surface be "
" shape, play static probe.The probe hold-down nut sound end have "
The shape fixed card slot can block probe, takes off in case probe is outer.
Probe has heat insulating mattress to separate with probe hold-down nut contact site, in case inner optical fiber and thermal detector transmission line are damaged in the probe heat transfer to popping one's head in fixed handle.
Main feature of the present invention is
1) since probe adopt can be high temperature resistant, bright, printing opacity, not easily broken material be (as quartz glass, white stone etc.) make the probe of various various outer diameter specifications, therefore, can take the circumstances into consideration the corresponding spy of adapted pass according to Different Organs position and focus situation, probe is contacted with intraorganic focus, and helping popping one's head in is passed to the focus of contact site after generating heat rapidly; Can be used as a kind of intermediate light thermoconverter, both can keep the performance characteristic of original optical maser wavelength to the target area tissue, can be transform light energy heat energy again rapidly, efficiently, accurately grasps the effect degree of laser to the target area tissue by thermometric; Its clinical practice safety, efficient.
2) the probe fixed handle adopts sped structure, is made up of hold-down nut and fixed screw, and is movable removable, uses freely.
3) probe has heat insulating mattress to isolate with probe fixed handle contact site, in case the probe high temperature heat transfer is damaged optical fiber temperature-measurement device transmission line to popping one's head in handle.
4) there is thermal detector to change, and makes probe keep temperature constant state, science data are provided for clinical hyperthermia treatment of carcinoma by temperature regulating device in external direct observation probe temperature inside.
5) adopt soft spring metal pipe that can be bent as the overcoat of optical fiber and thermal detector transmission line, can join scope and enter the intracavity organ and look at treatment straight.
The hyperthermia treatment that mainly is adapted to the intracavity organ that some scope can reach is carried out tumor is closed in this spy, and hemorrhage treatments such as coagulation.Diseases such as main treatment esophageal carcinoma, gastric cancer, rectal cancer, nasopharyngeal carcinoma, bladder cancer, pulmonary carcinoma, official's neck cancer and gastrorrhagia, polyp of stomach.
