Preferably, the leading section of described cutter head is provided with ceramic head.
Preferably, in described insulation protection tube, be provided with termination, described cutter head runs through described termination and can slide relatively described termination.
Preferably, the slide of described operating portion is provided with the adapter portion that can be electrically connected to high frequency generating apparatus.
Effect of the present utility model is: endoscope-use high-frequency knife of the present utility model, and when operation, can constantly rinse operative incision and make ongoing surgical field of view more clear, cut in time easily and effectively sufferer tissue, and the operation of being more convenient for.
Accompanying drawing explanation
Fig. 1 is the structural representation of endoscope-use high-frequency knife of the present utility model.
The specific embodiment
Fig. 1 is the structural representation of endoscope-use high-frequency knife of the present utility model, and endoscope-use high-frequency knife of the present utility model, comprising: an insulation protection tube 2; One cutter head 1, it is inserted in described insulation protection tube 2, has the leading section of the overhang of relatively described insulation protection tube 2 front ends of capable of regulating; One operating portion 3, it comprises operating portion main body 302 and can be along the slide 301 of the axis linear slide of described operating portion main body; In described cutter head 1, be provided with flushing hole 101, the rearward end of described cutter head 1 connects a flushing pipe 103, and described flushing hole 101 is communicated with flushing pipe 103; Described operating portion is provided with a flushing interface 305, and described flushing interface 305 is communicated with described flushing pipe 103.
Described flushing interface 305 and described flushing pipe 103 mode of communicating; can adopt and on flushing pipe 103, offer a plurality of apertures; the flushing water entering from flushing interface 305 is introduced in insulation protection tube 2, then enters described flushing pipe 103 by the aperture of offering on flushing pipe 103.
Endoscope-use high-frequency knife of the present utility model is in operation process, owing to there being oozing out of blood to make the visual field fuzzy, at this moment can adopt water to rinse, water can inject by rinsing interface 305 with syringe, by flushing pipe 103, water is gone out from the flushing hole 101 of cutter head 1 again, make constantly to rinse operative incision when operation and make ongoing surgical field of view more clear, the operation of being more convenient for.When operation, can also utilize 305 dozens of contrast agent of this flushing interface, make diseased region more obvious, to operation, operate more purposive.
In insulation protection tube 2, be provided with electric conductivity operating line 102, its one end is connected with the rearward end of cutter head 1, can operate the overhang of relatively described insulation protection tube 2 front ends of leading section of cutter head 1.The rearward end of described cutter head 1 and described flushing pipe 103 and electric conductivity operating line 102 link together.
Operating portion 3 comprise operating portion main body 302, can be along the slide 301 of the axis linear slide of operating portion main body 302; one end of operating portion main body 302 is flexibly connected with the base portion of electric conductivity operating line 102; its other end connecting handle 304; slide 301 is connected with the base portion of insulation protection tube 2, and slide 301 is provided with the adapter portion 303 being electrically connected to high frequency generating apparatus.The handle 304 of operating portion main body 302 base portions has the ring of placing finger use, operation has in the direction of the axial quadrature with operating portion main body 302 ring of placing finger use with slide 301 equally, thumb is stretched in the ring of handle 304, forefinger and middle finger stretch in the ring of slide 301, can operate slide 301, its relative operating portion main body 302 is slided.
During operation, doctor controls slide 301 and the operating portion main body 302 of operating portion 3, slide 301 is rearward moved relative to operating portion main body 302, electric conductivity operating line 102 forwards moves relative to insulation protection tube 2 together with handle 304, the leading section of cutter head 1 is outstanding towards the outside from insulation protection tube 2 front ends, this using state for switching on and excise mucosa to cutter; After operation finishes, slide 301 is forwards moved relative to insulation protection tube 2, electric conductivity operating line 102 rearward moves relative to insulation protection tube 2, and the main part of cutter head 1 enters insulation protection tube 2 inside, and this is not for using the state of cutter.
At control handle 304 and operating portion main body 302 front and back, slide, just can make the leading section extension elongation of cutter head 1 can control to Len req by electric conductivity operating line 102, the depth of cut to mucosa during with direct control operation.The leading section of described cutter head 1 is provided with ceramic head 104, when cutting and organizing, ceramic head 104 plays insulating effect, even if when operation, cutter head 1 can surpass desired depth like this, also only effects on surface mucosa cuts and unlikely damage coat of the stomach or intestinal wall, to avoid larger wound.
In described insulation protection tube 2, be provided with termination 201, described cutter head 1 runs through described termination 201 and can slide relatively described termination 201.
Those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; in order to make those skilled in the art can better understand this patent content; should not be understood as the restriction to this patent protection domain; so long as disclose spiritual do any according to this patent, be equal to change or modify, all falling into this patent protection domain.
