Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described:
Endoscope-use diagnosis and treatment sheath pipe described in the utility model, according to setting endoscope path way and instrument channel in it, can be divided into single channel diagnosis and treatment sheath pipe and multichannel diagnosis and treatment sheath pipe according to the quantity of instrument channel.
Embodiment one
As shown in Figure 1, endoscope diagnosis sheath pipe described in the utility model, it includes sheath pipe axle 1, described sheath pipe axle 1 includes working tips 2 and operation end 3, sheath pipe axle 1 is triple hollow tubular structures of outer tube, intervalve, interior pipe composition, interior pipe is once-forming, forms the endoscope path way 11 that a front end is closed;Its middle pipe forms the operating walk way 12 do not closed of a front end, apparatus that described operating walk way is integrated and Inlet and outlet water passage, and working tips 2 front end sets suction eye 21.Operation end 3 is positioned at sheath pipe axle 1 rear portion, is positioned at sheath pipe axle 1 rear portion including the bayonet socket 31 coordinated with endoscope, apparatus entrance 32, water inlet 33 and outlet 34.
Different according to the design of sheath pipe axle 1 built-in function passage, the endoscope-use diagnosis and treatment sheath pipe described in the present embodiment has following two version:
The first, as shown in Figure 2, described operating walk way 12 is the passage that instrument channel, intake tunnel and exhalant canal carry out integrated design, there are endoscope path way mouth 111, operating walk way opening 112 in the first end of described sheath pipe axle 1, described endoscope path way mouth 111 completely encloses, with endoscope with the use of time so that the working tips of endoscope will not with direct body contact.
The second, as it is shown on figure 3, the interior pipe of described sheath pipe axle 1 forms an independent endoscope path way 11, described intervalve forms the operating walk way 12 of three isosceles triangle arrangements.This operating walk way 12 respectively three separate instrument channel, intake tunnel and exhalant canal, these three passages are isosceles triangle arrangement, wherein instrument channel is positioned below, both sides are intake tunnel and exhalant canal, described apparatus entrance 35, water inlet 36 and outlet 37 are positioned on rear side of sheath pipe axle 1, parallel arranged, described instrument channel diameter is be more than or equal to 2.8mm.In addition, as shown in Figure 4, there are endoscope path way mouth 113, apparatus outlet 114, intake tunnel opening 115, pump mouth 116 in the first end of described sheath pipe axle 1, and described endoscope path way mouth 113 is the same with single channel diagnosis and treatment sheath pipe, completely enclosed, the working tips making endoscope will not with direct body contact.
As it is shown in figure 5, described endoscope path way 11 front end is closed, being completely independent with the instrument channel of lower section, closing place P in front end is shaped as mellow and full hemispherical, material therefor highly transparent;Front end closing place inwall outer wall all scribble do not get wet/oil colourless transparent coating, make the automatic landing of body fluid, blood or steam being stained with during operation, do not affect mirror downward view.
In this utility model, owing to endoscope path way 11 is completely enclosed and is completely independent, Contamination of Endoscopes can be prevented, therefore when implementing diagnosis and treatment for different patients continuously, only need to change diagnosis and treatment sheath pipe.
Embodiment two
As shown in Figure 6, the front end outer side of described sheath pipe axle 1 can install an air bag 18, airway 19 can be passed through in sheath pipe axle 1 be connected with air bag 18, the air inlet 20 of airway 19 tail end is connected with air bag pressure gauge 21, air bag pressure gauge 21 has inflation bulb 22 and release button 23, inside air bag pressure can be monitored and regulate.Described airway 19 is imbedded in the gas injection chamber between outer tube and intervalve, described air bag 18 is high power capacity low pressure air bag, and cylindric, before unaerated, diameter is a bit larger tham sheath tube wall, the outer wall inflating backward sheath pipe axle 1 expands prominent, Fig. 6 also show that described air bag 18 full after form.
In this utility model, surrounding tissue can be played buffering, protection and fixing effect by described air bag 18, replaces inflation or topping up, exposes operative site, it is thus achieved that enough operative spaces and the clearly visual field.The specification of the air bag 18 of described sheath pipe axle 1 and front end, because being suitable for that position and supporting endoscope be different and difference to some extent, should need to select with caution suitable diagnosis and treatment sheath pipe or air bag according to the structure of insertion site and feature and operation during practical application.In practical operation, need to closely monitor intracapsular pressure, cause balloon rupture in case interior pressure is excessive or surrounding tissue is caused excessive compressing.
In this utility model, described sheath pipe axle 1 can be made up of rigid or flexible metal or macromolecule or nano material.Front end closing place of endoscope path way 11 manufactures material and answers highly transparent, and front end closing place should scribble/the colourless transparent coating of oil that do not get wet, thus preventing body fluid, blood, steam etc. from sticking interference mirror downward view;The manufacture material of intervalve should have certain hardness, and to maintain the intrinsic shape of operating walk way, it is simple to apparatus passes in and out, described sheath pipe axle 1 can be coated with hydrophilic lubrication coating with human contact face, reduces the friction with surrounding tissue.
