Description

A kind of Microendoscopic auxiliary visual field balloon-system

Technical field

The utility model relates to area of medical devices, especially a kind of Microendoscopic auxiliary visual field balloon-system.

Background technique

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；Blood vessel, nerve and lymphatic vessel rich in inside submucosa, this be also tumour once grow into it is viscous Film lower layer, it is possible to the main reason for shifting；Submucosa there are one feature, be exactly it is very loose, use injection needle To its injecting fluid, so that it may submucosa be 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, has little effect to the state of whole body, in no complication In the case where, diet can be restored within patient postoperative 24 hours, can left 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 art requires very high, mucous membrane to the endoscopic technic of operation doctor at present Removing operating time it is long, if mucous membrane is dealt with improperly when removing and will cause the complication such as bleeding, perforation.

Utility model content

Purpose of utility model: technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide one Kind Microendoscopic auxiliary visual field balloon-system.

In order to solve the above-mentioned technical problem, the utility model provides a kind of Microendoscopic auxiliary visual field balloon-system, Including sacculus and the tube body being connected to sacculus, in tube body end, sacculus is equipped with more than one be used for for the sacculus setting The coil that carry operation is pressed from both sides with tissue.

In the utility model, the sacculus includes sacculus inner core and balloon body, the sacculus inner core and balloon body it Between be equipped with more than one through-hole, the tube body is connected to sacculus inner core.

In the utility model, there are four the coils.

In the utility model, angle is 90 degree between the adjacent coil, guarantees that tissue folder scatter, the folder of large area Firmly lesions position.

In the utility model, the tube body is equipped with connector away from one end of sacculus, and connector and tube body are tightly connected, prevent Only sacculus gas leakage, auxiliary access syringe is inflated or filling liquid.

In the utility model, the connector is equipped with dismountable check valve, prevents sacculus gas leakage.

In the utility model, cross section after the balloon expandable is flat apple shape, the shape of sacculus similar to apple form, More tissues are encased with the smallest height, also facilitate the arrangement of coil.

In the utility model, after balloon expandable, local organization is strutted, cooperates endoscope, expands the visual field, convenient for tissue folder Release is implemented convenient for operation.

The utility model has the advantages that the present apparatus can quickly and effectively assist smoothly completing for ESD operation, shorten operating time, mitigates Patient suffering reduces the labor intensity of doctor, so that ESD mucous membrane is sufficiently exposed under endoscopic visual.

Detailed description of the invention

The utility model is done with reference to the accompanying drawings and detailed description and is further illustrated, the utility model Above-mentioned or otherwise advantage will become apparent.

Fig. 1 is the cross-sectional view of the present apparatus；

Fig. 2 is the cross-sectional view of band connection head and check valve；

Fig. 3 is structural schematic diagram；

Fig. 4 is using schematic diagram.

Specific embodiment

It elaborates below in conjunction with attached drawing to the utility model.

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 in the present embodiment, and sacculus 3 preferably uses rubber material, and coil 4 is preferably adopted Use nylon wire.

There are four coils 4, and angle is 90 degree between adjacent coil 4.Guarantee 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 the smallest height.

Such as Fig. 2, check valve 7 and connector 6 are connected to tube body proximal end.When ESD operation, as desired by check valve 7 Air inlet or feed liquor body, check valve 7 are not necessarily to secondary locking；If midway, which needs to deflate or discharge liquid, can revolve 7 for check valve 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 pressure pump of pressure maintaining.

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 early cancer position, and lower endoscope carries out Label cuts backed off after random endoscope；This auxiliary traction sacculus endoscopically is parallel, then take 1PC tissue to be clipped in remote in pincers road The one of coil of sacculus coil 4 is clamped at end, and the utility model endoscope and tissue are pressed from both sides while being fed through at the surface of a wound；By this group It knits folder and clamps 10 edge of mucous layer, discharged after clamping, withdraw from an organization clamp body, and the same manner distinguishes other three coils 4 of Fig. 3 Uniformly folder is pressed from both sides with tissue to close in surface of a wound edge；

Sacculus injection is expanded into using pressure pump or Syringe injector injected gas or liquid suitably sized, made It obtains and is exposed under endoscopic visual in submucosa ring week；

Lower band function of injection ESD electric knife, injecting normal saline or other liquid swell submucosa 9, start into Removing under the corresponding mucous membrane of row is until early cancer

The tissue endoscopically and sacculus of removing are taken out of in vitro together after all stripping.

The utility model provides a kind of Microendoscopic auxiliary visual field balloon-system, implements the side of the technical solution There are many method and approach, and the above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.Existing skill can be used in each component part being not known in the present embodiment Art is realized.
