Abstract
For in gastroscope operation operating process, it is difficult to using existing various auxiliary traction technologies, the utility model is provided with a kind of gastroscope up-stripping component in the prior art, including：One can hold the cuff of injection liquid, and the cuff is provided with an inlet and the inlet and is provided with unidirectional liquid-filling valve, and the cuff is provided with holding section.The utility model compared to existing technologies, can fully expose surgical field of view, and can effectively aid in the stripping of diseased region in gastroscope strip operation art journey.
Description
Technical field
The utility model belongs to surgical operating instrument technical field, more particularly to a kind of gastroscope up-stripping component.
Background technology
Under the scope come by EMR (endoscopic mucosal resection, EMR) evolution
For mucous membrane decollement (endoscopic submucosal dissection, ESD) because its complete resection rate is high, security is good, makes
The idicatio of alimentary canal morning cancer and other tumor resections expands, progressively as well accepted microinvasive surgical teatment mode.Inside
During mucous membrane decollement was implemented under mirror, there are three basic step art formulas, i.e. submucosal injection, the annular incision of perilesional mucous membrane
With the stripping of lesion sub-mucosal tissues.
Some ESD are treated with the focus at difficult position, the submucosal injection being usually taken repeatedly carries for subsequent peeling operations
The surgical field of view of limit is provided with, but injection can extend operating time repeatedly, increase bleeding, the danger of perforation.It is another simple
Scheme is that adjustment patient posture can be attempted according to the direction of gravity, release surface is obtained preferable tension force, obtains the operation visual field, but
In some operations (being related to upper digestive tract), the optional position of patient is limited, limits its using effect.Therefore how in art
There is provided good " surgical field of view " turns into the key to solve the above problems.
After being inspired by surgery drawing technology, various scope auxiliary traction technologies are arisen at the historic moment.By tractive force source
Position can be roughly divided into traction in vivo and external traction；Metal clip silk thread combined drawing skill can be divided into again by being formed by draw-gear
Art, metal clip elastic ring combined drawing technology, S-O metal clips traction technique, magnetic anchor technology etc..But when being grasped in gastroscope
When making, it is only capable of accommodating single operation device, above-mentioned each auxiliary traction technology is difficult application.
The content of the invention
The utility model provides one kind compared to existing technologies to solve technical problem present in known technology,
Surgical field of view can be fully exposed in gastroscope glass operates art journey, and the gastroscope auxiliary that can effectively aid in lesion to peel off
Peel off component.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of gastroscope up-stripping component, including：One can hold the cuff of injection liquid, and the cuff is provided with an injection
Unidirectional liquid-filling valve is installed on mouth and the inlet, the cuff is provided with holding section.
The utility model can also use following technical measures：The holding section is clip or hook.
The utility model has the advantages and positive effects of：
In summary, the utility model can cured by providing a kind of gastroscope up-stripping component in gastroscope operation
Enter patient's stomach under the operation of teacher, then, be connected to using holding section in tumour to be stripped, afterwards, utilize external note
Water installations are to intracapsular injection liquid is covered, until cuff is in expanded state, now, you can extract water injecting pipeline out.With operation
Carry out, gastroscope up-stripping component provided by the utility model will drive tumour to one away from muscle layer under gravity
Side pulls, so that surgical field of view can be exposed to greatest extent, until, tumour is cut off completely, after the completion of operation, can break set
Capsule, releases its interior liquid, and the cuff so collapsed is also very easy to take out out of alimentary canal.
Improvement based on above-mentioned technical proposal, the cuff in the utility model, is critical component of the present utility model, is used for
The liquid of injection is held, when covering intracapsular no liquid injection, cuff size is smaller, is very easy to enter abdominal cavity；Filled when set is intracapsular
It is full of when having liquid, the increase of cuff gravity, good draw can be played；Unidirectional fluid injection is installed at the inlet of cuff
Valve, it is used to be connected with external liquid-injection equipment, after the completion of fluid injection, even if removing liquid-injection equipment, covers intracapsular liquid also not
It can flow back.Holding section, for the utility model to be connected to diseased region mucous membrane to be stripped.Based on above-mentioned optimization technique side
The improvement of case, the holding section in the utility model both can be hook or clip, as long as can consolidate the utility model
It is scheduled in tumour to be stripped.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model (unimplanted)；
Fig. 2 is structural representation of the present utility model (injection).
In figure：1st, cuff；2nd, inlet；3rd, unidirectional liquid-filling valve；4th, holding section.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as the technical characteristic being related in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
Embodiment one：
Fig. 1 and Fig. 2 are referred to, a kind of gastroscope up-stripping component is provide in particular in the present embodiment.
The gastroscope up-stripping component, including：One can hold the cuff 1 of injection liquid, and the cuff 1 is provided with a note
Unidirectional liquid-filling valve 3 is installed, the cuff 1 is provided with holding section 4 on entrance 2 and the inlet 2.
Cuff, it is critical component of the present utility model in above-mentioned design, for holding the liquid of injection, when the intracapsular nothing of set
When liquid injects, cuff size is smaller, is very easy to enter abdominal cavity；When cover it is intracapsular it is full have liquid when, the increase of cuff gravity, energy
Enough play good draw.
Unidirectional liquid-filling valve is installed, it is used to be connected with external liquid-injection equipment, when fluid injection is completed at the inlet of cuff
Afterwards, even if removing liquid-injection equipment, covering intracapsular liquid will not also flow back.
Holding section, for the utility model to be connected to tumour to be stripped.
In any preferred embodiment, the holding section 4 is clip or hook.
Application method：
In gastroscope operation, the utility model of unimplanted liquid is inserted patient's stomach by doctor first, then, utilizes card
The portion of holding is connected in tumour to be stripped, afterwards, using external water filling device to intracapsular injection liquid is covered, until cuff is in
Expanded state, now, you can extract water injecting pipeline out.With the progress of operation, gastroscope up-stripping group provided by the utility model
Part will drive tumour to be pulled to the side away from muscle layer under gravity, be regarded with that can expose operation to greatest extent
Open country, until, tumour is cut off completely.
After confirming that operation is fully completed, it can be drawn off as long as doctor punctures cuff, the mode of taking-up is unlimited,
Such as：Gastroscope clamping taking-up etc..
The utility model has good using effect in the tumour of stomach large-size peels off operation.
It these are only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of the art
Member for, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
