High-frequency current pass sequentially through be conductively connected head 66, control steel wire 52, pipe coupling 51 and weakness connector 3 after pass to scissors
Ontology 6 is directly cut in the base of a fruit of polyp at this point, scissors ontology 6 may act as the use of high frequency electric knife, is not necessarily to snare,
The process of operation can not only be accelerated, and the difficulty of operation can be reduced.
Embodiment 2
The present embodiment based on embodiment 1, the present embodiment difference from example 1 is that, knife in the present embodiment
The surface of piece is covered with anti-stick coating, and anti-stick coating can be any metal coating in gold, copper or nickel coating, anti-stick
Coating can effectively prevent under multi-functional endoscope scissor electric knife as high frequency electric knife in use, tissue is bonded in sawtooth because burning
On 621.
Embodiment 3
The present embodiment based on embodiment 2, the present embodiment and embodiment 2 the difference is that, in the present embodiment
The outer surface of first clamping member 61 and the second clamping piece 62 is covered with 2-8 layers of insulating materials, in addition, the outer surface of fixing seat cylinder 2
2-8 layers of insulating materials are again covered with, but it's not limited to that for the number of plies of insulating materials, the preference of insulating materials is silica gel.
The covering method of silica gel is only to guarantee that blade not by plated film, makes liquid by immersing in liquid silica gel to blade plus after shield
Body silica gel and its appearance face contact, then scissors ontology 6 is taken out, after the liquid silica gel solidification on 6 outer surface of scissors ontology, then
By scissors ontology 6The covering for entering to carry out second layer silica gel in liquid silica gel can cut by the way that the above process is repeated several times
The outer surface of knife ontology 6 covers multilayer silica gel.
In use, scissors ontology 6 is delivered to predetermined position under the Lookout assist of endoscope, will be conductively connected head 66 with
The connection of high frequency electric source output equipment, forward slip lever 11, scissors ontology 6 open, and the second clamping piece 62 is used as high frequency at this time
Electric knife uses, and is directly cut in the base of a fruit of polyp using the sawtooth 621 on the second clamping piece 62, and polyp cutting finishes
Afterwards, operating handle 1 is rotated, operating handle 1 drives scissors ontology 6 to rotate by control steel wire 52, by first clamping member 61 and the
Two clamping pieces 62 are adjusted to the base of a fruit two sides of polyp, slide backward lever 11, and scissors ontology 6 is closed, and the base of a fruit of polyp is pressed from both sides
In scissors ontology 6, at this point, scissors ontology 6 is used as hemostasis tool, scissor electric knife under multi-functional endoscope of the invention is used
The process that can accelerate operation, reduces the difficulty of operation, reduces the time that instrument passes in and out the waste of biopsy duct repeatedly, not only may be used
Quickly to handle lesion and the surface of a wound, the integrated operation time is saved, it is inconvenient to reduce replacement instrument bring, but also expense can be saved
With the expense of two kinds of instruments to be reduced to a kind of expense of instrument.
Although being above described in detail with generality explanation and specific embodiment to the present invention, at this
On the basis of invention, it can be modified or is improved, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
