Description
What the present invention relates to is that a kind of stomach, intestinal bleeding of being mainly used in stops blooding safely and fast and burn and remove the microwave endoscope therapeutic instrument of polyp.
Prior art is mainly assisted major parts such as penetrating device by control, power supply, microwave source and antenna and is formed.Because microwave and infrared, ultrashort wave etc. are relatively, it has darker penetration power, can accelerate blood circulates and advantage such as irradiation treatment.Yet it is confined to form of irradiation, high-powerly also can only carry out diathermanous treatment even add, and it can't carry out hemostasis to inner chamber, the treatment functions such as removing polyp of burning.See also
The objective of the invention is to problem, propose a kind of stomach, intestinal bleeding of can be used for and stop blooding safely and fast and burn and remove the microwave endoscope therapeutic instrument of polyp at above-mentioned existence.
Technical solution of the present invention and action principle thereof: basic structure is made up of control section and safe timing means JSB thereof, power pack, microwave generator (magnetron), the first-class institute of go in ring protector and microwave output system and special microwave antenna.Control section refers at power supply two ends serial connection Zero-point switch K

2, the g-load relay J
2And interchange contact-relay J
1, and with display lamp ZD
1Be in parallel; Safe timing means JSB mainly adopts the integrated circuit JEC-2B of highly sensitive low-power consumption
2As triggering and driver element, control the contact with the contact of the small-sized middle power relay J of JZX-2F as output, they are serially connected in transformator B
1Primary side AA and transformator B
2Primary side BB between; Power supply: pressure regulator BT is serially connected between the 220V input voltage, the outfan of pressure regulator BT and transformator B
1elementaryly join, magnetron heater transformator B
2Secondary end and magnetron G
5Filament join; Microwave output system and special microwave antenna head: by coaxial fitting A
1, be the coaxial patch plug of 50 Ω N types of standard, be used for connecting microwave magnetron delivery and coaxial cable, standard 50 Ω coaxial cable A
2, be used for Transmission Microwave, circulator A
3Have three branches (11; 22; 33); be input to a certain ramose microwave; can only pass to another branch with the direction of going in ring counterclockwise; as 11 termination magnetrons input microwave; make 22 ends through circulator, the echo from 22 ends reflect can only pass to 33 ends; at the full matched load of 33 terminations; just can not get back to 11 ends, this has just protected the steady operation of magnetron, even the serious mismatch of 22 ends; do not damage magnetron yet; the technical specification that can reach is that the forward decay should be less than 0.5 decibel, and reverse attenuation should be greater than the 20-30 decibel, and standing-wave ratio should be no more than 1.25 less than 1.05 maximums; working band is wide, and frequency range is at 2450 ± 50MH
z, bear more than the power 300W circulator A
3Be exactly go in ring protector, standard 50 Ω transit joint A
4, be used for standard 50 Ω coaxial cables carry out the transition to diameter only for the coaxial cable of 2.5mm, by the special thin coaxial cable A that transmits microwave of endoscope movable detecting hole
5, it requires diameter less than 2.5mm, bears more than the power 300W, and is high temperature resistant more than 200 ℃, and its length is that the length that is used to control stomach is 1600mm, and the length that is used to control intestinal is 2000mm, a special antenna treatment A
6, hollow and coaxial inner conductor link into an integrated entity in it, adopt the red copper material to guarantee the conversion of good power delivery and heat, to be used for its end of hemostatic A
7, be the knob shape, seven parts such as tip body of removing polyp that are used for burning are formed.Its action principle: as key switch AN
1Close, filament begins preheating, simultaneously low pressure display lamp ZD
1Bright, the adjusting knob of pressure regulator BT is transferred to zero-bit, make Zero-point switch K
1Close, treat to transfer BT after the preheating about 3 minutes, by silicon rectifier BG(
1-4) negative high voltage after the rectification is added to magnetron G
5Negative electrode on, the plus earth of magnetron, this moment HT pilot ZD
2Bright, when negative high voltage reached starting of oscillation numerical value, magnetron was just started working.Transfer BT to arrive required magnitude of power again, its watt level is by ammeter CB(MA table), the output of magnetron is by circulator A

Time is all 10 " plays effect with interior
As seen, the present invention can reach the hemostasis purpose under scope in the experiment, even under the situation of heparinization, microwave still can play the effect of coagulation.From pathological section, microwave is only in top layer mucosa generation consolidation and deep layer does not have special change, this may be relevant with the applied microwave amount, but also is to confirm that its therapeutic dose is safe, can supply clinic trial, its suitable microwave amount 60-80MA.
Applied microwave treats acute activeness upper gastrointestinal hemorrhage by scope (XS-4, FG-34JA) and pipe intestinal polyp is feasible.Particularly wide base or the subzone polyp to snare TURP difficulty has than sound value.
Acute hemorrhage of upper gastrointestinal tract, acute active hemorrhage person's 4 examples of micro-wave therapeutic under the scope, applied microwave 80MA * 10 " * 2 times; 60MA * 10 " * 4 times, " the satisfied haemostatic effect of * 2 acquisitions, in the therapeutic process, the patient does not have any discomfort sensation in 70MA * 3.
Micro-wave therapeutic pipe intestinal polyp totally 13 examples under the scope, its result is as follows:
