The purpose of this utility model will be achieved through following technical scheme:
A kind of puncturing lever; Comprise body and be positioned at the vertical puncturing lever of said body tip, said body is arranged with sleeve assembly outward, and is gapped between said body and the sleeve assembly; Said sleeve assembly is provided with the QI KOU that connects that is connected with source of the gas; Said body is provided with an independently air flue, and the outlet of this air flue and inlet all are located on the said body, and the hollow of said air flue and puncturing lever body intercepts each other.
Preferably, be adjacent to the most advanced and sophisticated part of said puncturing lever on the said body and be provided with at least one flank, said air flue only is opened in the said flank.
Preferably, said body is provided with 2 flanks, is equipped with an independently air flue in each flank.
Preferably, the parallel axes of the axis of said air flue and flank.
Preferably, the most advanced and sophisticated distance of the outlet of said air flue and said puncturing lever is between the 2-4 millimeter.
Preferably, the exit of said air flue is provided with a step that is used for molding.
Preferably, be adjacent to the most advanced and sophisticated part of said puncturing lever on the said body and be provided with at least one independently air flue, the parallel axes of said air flue is in the outline of said puncturing lever.
Preferably, the outlet of said air flue is perpendicular to the axis of said air flue.
Preferably, one-body molded in the said body have a trachea, and said air flue is the pipe passage of said trachea, and the hollow of said trachea and puncturing lever body intercepts each other.
Preferably, said pipe passage and said inner body wall coupling, the outlet of said trachea and inlet are all perpendicular to the outline of said puncturing lever.
The beneficial effect of this utility model is mainly reflected in: simple in structure, cost is low, and both having had after its puncturing lever tip punctures the stomach wall inner membrance is inflatable function, can the feedback information that pierces through stomach wall be provided to the doctor again.

The specific embodiment
A kind of perforator, as shown in Figure 1, consistent with prior art comprises: sleeve assembly 7 and the puncturing lever 10 that places in it, be provided with gap 6 between said sleeve assembly 7 and the puncturing lever 10, said sleeve assembly 7 be provided be connected with source of the gas connect QI KOU 8.Said puncturing lever 10 comprises: body 1 and be positioned at said body 1 vertical puncturing lever most advanced and sophisticated 2.Said body 1 comprises a hollow 11.Be adjacent to most advanced and sophisticated 2 parts of said puncturing lever on the said body 1 and be provided with at least one flank 3, in general, be provided with symmetric even number flank 3 around the said puncturing lever most advanced and sophisticated 2, be generally 2.
To first embodiment shown in Figure 4, be provided with an independently air flue 4 like Fig. 1 in the said flank 3.The outlet 41 of this air flue 4 all is located on the said body 1 with inlet 42, promptly on the flank 3.The parallel axes of the axis of said air flue 4 and flank 3.The distance of the outlet 41 of said air flue 4 and said puncturing lever most advanced and sophisticated 2 is between the 2-4 millimeter.Outlet 41 places of said air flue 4 also are provided with a step 43 that is used for molding.
As shown in Figure 9, in operation process, gas gets among the gap between sleeve assembly and the puncturing lever 6 from connecing QI KOU 8,42 enters in the air flue 4 from entering the mouth then, enters in the human body from exporting 41 at last.After said puncturing lever most advanced and sophisticated 2 punctured stomach wall inner membrance 2-4 millimeter, at this moment source of the gas can also can provide the feedback information that pierces through stomach wall to the doctor to inflating in the patient body through air flue 4.
This utility model second embodiment that Fig. 5 discloses, be with the difference of first embodiment: said body 1 is provided with 2 flanks, is equipped with an independently air flue 4 in each flank 3.Inflation can be more even like this.
This utility model the 3rd embodiment that Fig. 6 discloses; Because body 1 outside is not provided with flank 3 in this example; Be provided with one or more air flues 4 so be adjacent to most advanced and sophisticated 2 parts of said puncturing lever on the said body 1; The parallel axes of said air flue 4 is in the outline of said puncturing lever, and the outlet 41 of air flue 4 is perpendicular to the axis of said air flue 4.Present embodiment can be applied on the puncturing lever that does not need flank 3.
This utility model the 4th embodiment that Fig. 7 discloses, one-body molded in the said body 1 have a trachea 5, and said air flue is the pipe passage of said trachea 5.Said pipe passage and said body 1 inwall coupling, the outlet 51 of said trachea 5 and inlet 52 are all perpendicular to the outline of said puncturing lever.For the convenience of making, will form the trachea and the puncturing lever body integrated injection molding of air flue in this example, because the independent preparation of trachea is very convenient, so whole puncturing lever injection moulding is also more convenient.Certainly,, also can trachea 5 be directly injection-moulded in the material of body except trachea in this example 5 and said body 1 inwall coupling, only will export 51 with inlet 52 outside be located at said body 1 and get final product.
In this utility model; No matter be the air flue 4 that is set directly on the body 1; Still take shape in the trachea 5 on the body; All the hollow with the puncturing lever body is not communicated with, so this utility model just do not need extra being used to seal the sealing member of the hollow of puncturing lever body, so structure can be simple.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of this utility model.
