The air bag is arranged on the end portion of the sheath catheter, the operation space is enlarged through expansion of the air bag, good vision and large space are provided for observation and operations, and therefore the purpose of increasing the safety rate of the operations is achieved.
Description
Technical field
This utility model relates to a kind of medical equipment, specifically, relates to a kind of apparatus sheath.
Background technology
The raising of the rise of Wicresoft's medical science, especially interventional technique in recent years and the improvement of intervention apparatus, make the application of interventional medicine more and more extensive.Get involved the guiding that relies on medical imaging device, utilize puncture and microcatheter technology disease is diagnosed and treated, and take treatment as a main subject.It has that accurate positioning, wound are little, few intercurrent disease, curative effect are high, instant effect, the repeatable feature such as strong.Interventional therapy has become and medical treatment, surgical intervention the third-largest clinical treatment means arranged side by side.
Present endoscope apparatus sheath on the market enters field of operation as the apparatus ，Wei endoscope that gets involved human body a passage is provided.Current exploration technology, normally inserts endoscope apparatus sheath from chamber and the wound of human body, camera lens enters people's in-vivo tissue thereupon and observes.Yet, due to human body Nei Shu district spatial limitation, make the endoscope visual field limited, can not clearly observe and operation effectively, increased operation risk, cause operation safety rate to reduce.
Utility model content
The purpose of this utility model is to provide a kind of endoscope apparatus sheath, in the end of sheath pipe, is designed with air bag, can expand operative space by the expansion of air bag, can more clearly observe and more effectively operation.
To achieve these goals, the technical scheme that this utility model adopts is as follows:
A kind of endoscope apparatus sheath, be used for coordinating endoscope to use, comprise sheath pipe and be set in the inner core among described sheath pipe, described sheath pipe one end is provided with air bag, described sheath pipe has topping up passage, inflating catheter and bayonet socket, described inflating catheter and described topping up channel connection, described bayonet socket is locked and is coordinated with described endoscope.
Further, described sheath pipe adopts disposable plastic to make.
Further, described sheath pipe adopts reusable metal material to make.
Further, described air bag can be divided into ballonet and air vesicle.
Further, after described ballonet inflation, diameter is less than or equal to 50mm.
Further, described air vesicle is arranged on described sheath tube end, and after inflation, described air vesicle expands and expands described sheath tube end space.
Further, described inflating catheter connects the described air bag of described sheath tube end, can pass through injector to inject gas or liquid.
Further, the number of described air bag is more than or equal to one.
Compared with prior art, this utility model sheath tube end is designed with air bag, and the expansion by air bag expands operative space, for observing and operation provides the better visual field and space, thereby reaches the object that improves operation safety rate.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model endoscope apparatus sheath is described further.
Referring to Fig. 1 and Fig. 2, is the first embodiment of this utility model endoscope apparatus sheath, and described endoscope apparatus sheath is used for coordinating endoscope to use, and comprises sheath pipe 1 and is set in the inner core 2 among described sheath pipe 1.Described sheath pipe 1 one end is provided with air bag 3, and described sheath pipe 1 has topping up passage 11, inflating catheter 12 and bayonet socket 13, and described inflating catheter 12 is communicated with described topping up passage 11, and described bayonet socket 13 is locked and coordinated with described endoscope.
Refer to Fig. 1 and Fig. 2, in the present embodiment, described endoscope apparatus sheath is monosaccate form, and described air bag 3 is positioned at the front end of described sheath pipe 1 end 14.Described inflating catheter 12 connects the described air bag 3 of described sheath pipe 1 end 14, by injector to inject gas or liquid, gas or liquid enter described air bag 3 through described sheath pipe 1, form a larger air bag space, for observing and operation provides the better visual field and space, improve operation safety rate.
Described sheath pipe 1 can adopt disposable plastic to make, and also adopts reusable metal material to make.Described air bag 3 can be divided into ballonet and air vesicle.After described ballonet inflation, diameter is less than or equal to 50mm.Described air vesicle is arranged on described sheath pipe 1 end 14, and after inflation, described air vesicle expands and expands 14 spaces, described sheath pipe 1 end.The number of described air bag 3 is more than or equal to one.This utility model is not limited to this, and in other embodiments, described endoscope apparatus sheath also can adopt other materials to make.
Referring to Fig. 3, is the second embodiment of endoscope apparatus sheath described in the utility model, and the difference of itself and described the first embodiment is: described endoscope apparatus sheath is two air bag forms, and two described air bags 3 are separately positioned on described sheath pipe 1 end 14.
Referring to Fig. 4, is the 3rd embodiment of endoscope apparatus sheath described in the utility model, and the difference of itself and described the first embodiment is: described endoscope apparatus sheath is three air bag forms, and three identical described air bags 3 equidistantly distribute on described sheath pipe 1 end 14
Refer to Fig. 5, the 4th embodiment for endoscope apparatus sheath described in the utility model, the difference of itself and described the first embodiment is: described endoscope apparatus sheath is air vesicle form, described air bag 3 is arranged in most of length of described sheath pipe 1 end 14, after being expanded, described air bag 3 become tubular to expand, make space, art district larger, be convenient to organizing better outside described air bag 3 to observe.
This utility model sheath tube end is designed with air bag, and the expansion by air bag expands operative space, for observing and operation provides the better visual field and space, thereby reaches the object that improves operation safety rate.
More than describe preferred embodiment of the present utility model in detail, should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art according to this utility model design on prior art basis by logical analysis, reasoning or according to the available technical scheme of limited experiment, all should be among the determined protection domain by these claims.
