Specific embodiment
Embodiment 1
As shown in Figure 1-3, a kind of fiberoptic ductoscopy mirror sheath electroblation biopsy device, is made of mirror sheath 1 and electric knife 2, in which:
Mirror sheath 1 is the tubular structure that section is round or oval, and front end is bevel structure.
Electric knife 2 is arc, and both ends are connected with mirror sheath 1, and electric knife 2 is located at the 1 lower side of front end incline position of mirror sheath；Make
Used time, the horizontal position of a little higher than latex dust lens head of mirror sheath inclined-plane low dot location.
Electric knife 2 is connected with conducting wire, and conducting wire is placed in the 1 pars intramuralis traveling of mirror sheath, and nearly 1 tail portion Shi Yujing sheath 1 of mirror sheath separates, and with
External power is connected.
1 pars intramuralis of mirror sheath is additionally provided with irrigation channel 3 and attraction channel 4, and two channels are close to 1 front end inclined-plane low spot water of mirror sheath
Flat place is inwardly open on the inside of sheath wall.
Described device is additionally provided with multichannel crossover sub 7 (four-way), for logical with fiberoptic ductoscopy 5, positioning crochet hook 6, flushing
Road 3 is connected with attraction channel 4, has the function that closely to be connected.
Concrete operations:
In use, fiberoptic ductoscopy 5 is inserted into mirror sheath 1 first, then the two to be inserted into lesion together where in latex dust, pass through
Fiberoptic ductoscopy 5 searches out lesion in latex dust；It is placed in positioning crochet hook 6 through multichannel crossover sub 7, lesion in latex dust is caught on into fixation,
And it draws outward；It is powered to electric knife 2, further moving lens sheath 1, making arc electric knife 2 with mirror sheath 1, the direction into latex dust is mobile, will
Occupying lesion complete resection in latex dust；If there is bleeding or the big influence operation of smog, then the flushing using mirror sheath inner wall is needed
(irrigating catheter and negative pressure catheter are introduced with suction function by multichannel crossover sub 7, irrigation channel 3 is respectively toward to and attracts
Channel 4), to guarantee the clear of the visual field.When sample takes out, needs to position crochet hook 6 and extracted with mirror sheath 1 is outer together.
Embodiment 2
Difference from example 1 is that:
As shown in figure 4,1 inner wall of mirror sheath does not have irrigation channel 3 and attraction channel 4, but uses irrigating catheter 8 and inhale
Guiding tube 9 come realize corresponding function, irrigating catheter 8 and negative pressure catheter 9 through multichannel crossover sub 7 difference (triple channel conversion connect
Head) or (four-way crossover sub) is inserted into mirror sheath 1 simultaneously, to realize I & A function.
Embodiment 3
Difference from example 1 is that:
The irrigation channel 3 and attraction channel 4 of 1 inner wall of mirror sheath merge into a channel, when needing to rinse, will rinse
Conduit is inserted into the channel through multichannel crossover sub and is rinsed, and when needing to attract, irrigating catheter is extracted out, by negative pressure catheter
It is inserted into the channel through multichannel crossover sub (triple channel) to be attracted, to realize I & A function.
Embodiment 4
Difference from example 1 is that:
The electric knife 2 is overlapped with 1 bevel structure low dot location arc of mirror sheath, with the further occupy-place out of root excision latex dust
Venereal disease becomes.
Embodiment 5
With embodiment 4 the difference is that:
The electric knife 2 is overlapped with 1 bevel structure low dot location arc of mirror sheath, and 1 bevel structure low dot location of mirror sheath have it is scarce
Mouthful, i.e., there is gap between 1 wall front end of electric knife 2 and mirror sheath.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
In addition, there is omitted herein to descriptions of well-known structures and technologies, to avoid the utility model is unnecessarily obscured
Concept.
