Description
Technical field
The present invention relates to area of medical devices, especially a kind of Microendoscopic auxiliary visual field balloon-system.
Background technology
In recent years, with advances in technology, endoscope is not only already a simple diagnostic tool, to scope doctor
For, it is even more a good treatment tool.About alimentary canal stomach wall, according to there is mucous layer, submucosa, solid from the inside to surface
There are base and placenta percreta；Contain abundant blood vessel, nerve and lymphatic vessel inside submucosa, this be also tumour once grow into it is viscous
Film lower layer, it is possible to the main reason for shifting；There are one features for submucosa, are exactly very loose, use injection needle
To its injecting fluid, so that it may which, submucosa is strutted, ESD (endoscopic inferior mucosa lower layer decollement) is exactly to utilize submucosa
This feature after injection struts mucous layer, under endoscope direct-view, gradually completely strips down the lesion of mucous layer.ESD
Biggest advantage is minimally invasive, because of only local excision's mucous membrane, is had little effect to the state of whole body, in no complication
In the case of, patient can restore diet for postoperative 24 hours, can leave hospital within 3~4 days, meanwhile, the alimentary canals such as oesophagus or stomach are able to
Retain, its function will not be impacted.But clinic ESD arts require very high, mucous membrane to the endoscopic technic for operating doctor at present
Stripping operating time it is long, if mucous membrane is dealt with improperly when removing and can cause the complication such as bleeding, perforation.
Invention content
Goal of the invention：The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of endoscope
Lower auxiliary visual field balloon-system.
In order to solve the above technical problem, the present invention provides a kind of Microendoscopic auxiliary visual field balloon-systems, including
Sacculus and the tube body being connected to sacculus, in tube body end, sacculus is equipped with more than one for carry for the sacculus setting
The coil that operation is pressed from both sides with tissue.
In the present invention, the sacculus includes sacculus inner core and balloon body, is set between the sacculus inner core and balloon body
There are one above through-hole, the tube body is connected to sacculus inner core.
In the present invention, there are four the coils.
In the present invention, angle is 90 degree between the adjacent coil, ensures that tissue folder scatter, large area clamps disease
Stove position.
In the present invention, the tube body is equipped with connector away from one end of sacculus, and connector is tightly connected with tube body, prevents ball
Capsule gas leakage, auxiliary access syringe is inflated or filling liquid.
In the present invention, the connector is equipped with dismountable check valve, prevents sacculus gas leakage.
In the present invention, the cross section after the balloon expandable is flat apple shape, and the shape of sacculus is similar to apple form, with most
Small height encases more tissues, is also convenient for the arrangement of coil.
In the present invention, after balloon expandable, local organization is strutted, coordinates endoscope, expands the visual field, convenient for releasing for tissue folder
It puts, is implemented convenient for operation.
Advantageous effect：The present apparatus can fast and effectively assist smoothly completing for ESD operations, shorten operating time, mitigate
Patient suffering reduces the labor intensity of doctor so that ESD mucous membranes are sufficiently exposed under endoscopic visual.
Description of the drawings
The present invention is done with reference to the accompanying drawings and detailed description and is further illustrated, it is of the invention above-mentioned or
Otherwise advantage will become apparent.
Fig. 1 is the sectional view of the present apparatus；
Fig. 2 is the sectional view of band connection head and check valve；
Fig. 3 is structural schematic diagram；
Fig. 4 is to use schematic diagram.
Specific implementation mode
It elaborates to the present invention below in conjunction with attached drawing.
Embodiment：
Such as Fig. 1, a kind of Microendoscopic auxiliary visual field balloon-system, including sacculus inner core 1, through-hole are present embodiments provided
2, sacculus 3, coil 4, tube body 5, connector 6 and check valve 7；Four coils 4 are bundled in the proximal end of sacculus inner core 1, tube body 5 and ball
Intracapsular core 1 is glued connection, and the distal end of sacculus inner core 1 utilizes glue or other technology mode Seal treatments, the proximal end of tube body 5 and connection
First 6 are tightly connected.More than one through-hole 2 is equipped between sacculus inner core 1 and sacculus 3.
Sacculus inner core 1 preferably uses plastic pipe, sacculus 3 that rubber material, coil 4 is preferably used preferably to adopt in the present embodiment
Use nylon wire.
There are four coils 4, and angle is 90 degree between adjacent coil 4.Ensure that tissue folder 8 scatter, effectively clamps
Cut the edge of the surface of a wound.
At flat apple state after sacculus fluid injection body or gas injection, more tissues are encased with minimum height.
Such as Fig. 2, check valve 7 is connected to tube body proximal end with connector 6.When ESD performs the operation, as desired by check valve 7
Air inlet or into liquid, check valve 7 is not necessarily to secondary locking；If midway needs to deflate or check valve can be revolved 7 by release liquid
Under, or selection triple valve etc. other can rotate the valve body of deflation (liquid).Check valve 7 herein or other triple valves are non-must
Palpus part, this part can remove when using can be with the compression pump of pressurize.
The principle and application method of the present embodiment：
Principle：The present apparatus utilizes the scalability energy of sacculus 3, according to the size of the mucous membrane of incision inject suitable gas or
Liquid fixes sacculus body and injects liquid into after sacculus, and mucous layer can wrap sacculus utricule, ideally exposes under mucous membrane
Layer, it may also be necessary to pull that external tube body 5 is significantly more efficient to praise mucous layer, the weight of utricule 3 can also be utilized sometimes
Power adjusts the position of patient more effectively to expose submucosa.
Application method：Such as Fig. 3 and 4, the pre-operative preparation of body of stomach morning cancer ESD judges that early cancer position, lower endoscope carry out
Label cuts backed off after random endoscope；This auxiliary traction sacculus endoscopically is parallel, then take 1PC tissues to be clipped in remote in pincers road
4 one of coil of sacculus coil is clamped at end, and endoscope of the present invention and tissue are pressed from both sides while being fed through at the surface of a wound；By this tissue folder
10 edge of mucous layer is clamped, is discharged after clamping, withdraw from an organization clamp body, and other three coils 4 of Fig. 3 are used group by the same manner respectively
Knitting folder, uniformly folder is closed in surface of a wound edge；
Using compression pump, either sacculus injection is expanded into suitably sized by Syringe injector injected gas or liquid, makes
It obtains and is exposed under endoscopic visual in submucosa ring week；
Lower band function of injection ESD electric knives, injecting normal saline or other liquid swell submucosa 9, start into
Stripping under the corresponding mucous membrane of row is until early cancer
The tissue endoscopically and sacculus of stripping are taken out of in vitro together after all divesting.
The present invention provides a kind of Microendoscopic auxiliary visual field balloon-system, implement the technical solution method and
There are many approach, the above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.All undefined components in this embodiment can be implemented in the prior art.
