The other end of described sleeve pipe, the piston type asepwirator pump and the biopsy forceps control is arranged in the endoscopic views end
Handle processed and the endoscopic views end are located at the same end of described sleeve pipe.
Further, described sleeve pipe uses soft material, and three through holes, the scope connection is axially inside arranged
Pipe, biopsy forceps connecting tube, connection hose are each passed through three through holes；Wherein,
The scope connecting tube is fixed in the through hole where it, the biopsy forceps connecting tube and connection hose
Can the through hole where them slide axially.
Further, scope inserting end extension elongation in described sleeve pipe is no more than the biopsy binding clip and described
The extension elongation of air intake duct.
Further, the air intake duct can remove replacement from the connection hose, be disposable product.
Further, the air intake duct nozzle is internally provided with circle protrusion, and the tapered protrusion makes the air intake duct
Nozzle is in inner conical.
The utility model is generated by adopting the above technical scheme to be had the beneficial effect that:
The utility model struts notch using operation lesion mode, passes through leading for negative pressure adsorption equipment and lesion perienchyma
It pulls lesions position pull-up, so that biopsy forceps be facilitated to be sheared, reduces operation difficulty.

Fig. 4 is the utility model casing profile figure
In figure: 1 casing, 2 biopsy binding clips, 3 scope inserting ends, 4 air intake ducts, 5 biopsy forceps control handle, 6 connection hoses, 7
Biopsy forceps connecting tube, 8 scope connecting tubes, 9 endoscopic views ends, 10 piston type asepwirator pumps, 10a piston, 10b air pump cylinder, 10c piston
Handle, 11 breather cheek valves, 12 exhaust check valves,
Specific embodiment
With reference to the accompanying drawing and specific example, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Bright the utility model rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art
Member falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As shown in Figure 1,3, lesion removing equipment includes casing 1, scope, work under a kind of novel endoscope mucous membrane of the utility model
Inspection pincers and negative pressure adsorption equipment.
The scope includes scope inserting end 3, scope connecting tube 8 and endoscopic views end 9；The biopsy forceps includes biopsy
Binding clip 2, biopsy forceps control handle 5 and biopsy forceps connecting tube 7；The negative pressure adsorption equipment includes air intake duct 4, connection hose 6
And piston type asepwirator pump 10.
The air intake duct 4 by connect hose 6 connect with the piston type asepwirator pump 10, the connection hose 6 with it is described
10 junction of piston type asepwirator pump is internally provided with breather cheek valve 11, the piston type asepwirator pump 10 and the connection hose
One end of 6 connections is additionally provided with an exhaust check valve 12.Piston 10a is pulled by piston handle 10c, at this time breather cheek valve
11 open, and exhaust check valve 12 is closed；Piston 10a is pushed by piston handle 10c, breather cheek valve 11 is closed at this time, exhaust
Check valve 12 is opened.
For another example shown in Fig. 1,3,4, it is preferable that described sleeve pipe 1 uses soft material, to protect gastrointestinal tract wall, and makes institute
It states casing 1 and is readily bent adaptation gastrointestinal tract；It is opened along axial direction there are three through hole in described sleeve pipe 1, the connection hose 6, biopsy
