Description
Technical field
The present invention relates to a kind of puncturing lever of puncture outfit, belong to technical field of medical instruments.
Background technology
Puncture outfit a kind ofly pierces through stomach wall and provide the operating theater instruments entering lumenal passageway for other operating theater instruments, belongs to a kind of Minimally Invasive Surgery apparatus.Puncture outfit generally includes as the sleeve assembly of other operating theater instruments admission passages with through the puncturing lever in described sleeve assembly.In order to transdermal, first cut epiderm skin with scalpel, then puncturing lever transdermal enter body cavity.Apply pressure by the near-end to described puncturing lever, promote the tip of described puncturing lever through skin, until it enters body cavity.Puncture outfit enters body cavity, extracts puncturing lever out, and sleeve assembly just can as the mis instruments passage performing endo-surgical and endoscopy operation.
Disclose the puncturing structure with air-filled pore on a kind of puncturing lever tip in US Patent No. 20100081988, the benefit of this structure is namely inflatable after puncturing lever tip punctures stomach wall inner membrance, and provides the feedback information piercing through stomach wall to doctor.As shown in Figure 8, the gas port 8 that connects on sleeve assembly connects source of the gas, and puncturing lever body 1 is provided with entrance 42 and the outlet 41 of gas, and this outlet 41 is 2 millimeter apart from the distance at puncturing lever tip 2.When ventilating, gas, from connecing among gap 6 that gas port 8 enters between sleeve assembly and puncturing lever, then enters into the empty internal 11 of puncturing lever, finally enters in human body from outlet 41 from entrance 42.This structural design very good, but shortcoming is, because air flue is through the body empty internal of whole puncturing lever, to cause needing an extra seal 12 to carry out the sealing of puncturing lever body interior.So just make the complex structure of apparatus a lot, and bring the increase of cost.
Summary of the invention
The object of the invention is to propose a kind of structure simple, the puncturing lever that cost is low, both having had after its puncturing lever tip punctures stomach wall inner membrance is inflatable function, can provide the feedback information piercing through stomach wall again to doctor.
Object of the present invention, will be achieved by the following technical programs:
A kind of puncturing lever, comprise body and be positioned at the puncturing lever on described body top most advanced and sophisticated, sleeve assembly is arranged with outside described body, gap is had between described body and sleeve assembly, described sleeve assembly be provided be connected with source of the gas connect gas port, described body is provided with an independently air flue, and the outlet of this air flue and entrance are all located on described body, and the empty internal of described air flue and puncturing lever body intercepts mutually.
Preferably, described body is adjacent to the most advanced and sophisticated part of described puncturing lever and is provided with at least one flank, described air flue is only opened in described flank.
Preferably, described body is provided with 2 flanks, is equipped with an independently air flue in each flank.
Preferably, the axis of described air flue and the axis being parallel of flank.
Preferably, the outlet of described air flue and the distance at described puncturing lever tip are between 2-4 millimeter.
Preferably, the exit of described air flue is provided with one for shaping step.
Preferably, described body is adjacent to the most advanced and sophisticated part of described puncturing lever and is provided with at least one independently air flue, the axis being parallel of described air flue is in the outline of described puncturing lever.
Preferably, the exit normal of described air flue is in the axis of described air flue.
Preferably, one-body molded in described body have a tracheae, and described air flue is the pipe passage of described tracheae, and the empty internal of described tracheae and puncturing lever body intercepts mutually.
Preferably, described pipe passage mates with described inner body wall, and the outlet of described tracheae and entrance are all perpendicular to the outline of described puncturing lever.
Beneficial effect of the present invention is mainly reflected in: structure is simple, and cost is low, and both having had after its puncturing lever tip punctures stomach wall inner membrance is inflatable function, can provide the feedback information piercing through stomach wall again to doctor.

Detailed description of the invention
A kind of puncture outfit, as shown in Figure 1, consistent with prior art, comprising: sleeve assembly 7 and the puncturing lever 10 put in the inner, be provided with gap 6 between described sleeve assembly 7 and puncturing lever 10, described sleeve assembly 7 be provided be connected with source of the gas connect gas port 8.Described puncturing lever 10 comprises: body 1 and be positioned at the puncturing lever tip 2 on described body 1 top.Described body 1 comprises an empty internal 11.Described body 1 is adjacent to most advanced and sophisticated 2 parts of described puncturing lever and is provided with at least one flank 3, in general, the surrounding at described puncturing lever tip 2 is provided with symmetrical even number flank 3, is generally 2.
In the first embodiment as shown in Figures 1 to 4, in described flank 3, be provided with an independently air flue 4.The outlet 41 of this air flue 4 and entrance 42 are all located on described body 1, namely on flank 3.The axis of described air flue 4 and the axis being parallel of flank 3.The outlet 41 of described air flue 4 and the distance at described puncturing lever tip 2 are between 2-4 millimeter.Outlet 41 place of described air flue 4 is also provided with one for shaping step 43.
As shown in Figure 9, in surgical procedure, gas, from connecing among gap 6 that gas port 8 enters between sleeve assembly and puncturing lever, then enters in air flue 4 from entrance 42, finally enters in human body from outlet 41.After described puncturing lever tip 2 punctures stomach wall inner membrance 2-4 millimeter, source of the gas can be inflated in patient body by air flue 4, at this moment also can provide the feedback information piercing through stomach wall to doctor.
The second embodiment of the invention that Fig. 5 discloses, is with the difference of the first embodiment: described body 1 is provided with 2 flanks, is equipped with an independently air flue 4 in each flank 3.Such inflation can be more even.
The third embodiment of the invention that Fig. 6 discloses, owing to not being provided with flank 3 outside body in this example 1, so described body 1 is adjacent to most advanced and sophisticated 2 parts of described puncturing lever to be provided with one or more air flue 4, the axis being parallel of described air flue 4 is in the outline of described puncturing lever, and the outlet 41 of air flue 4 is perpendicular to the axis of described air flue 4.The present embodiment can be applied in do not need flank 3 puncturing lever on.
The fourth embodiment of the invention that Fig. 7 discloses, one-body molded in described body 1 have a tracheae 5, and described air flue is the pipe passage of described tracheae 5.Described pipe passage mates with described body 1 inwall, and the outlet 51 of described tracheae 5 and entrance 52 are all perpendicular to the outline of described puncturing lever.In order to the convenience manufactured, in this example, will form tracheae and the puncturing lever body integrated injection molding of air flue, because the independent preparation of tracheae is very convenient, so the puncturing lever injection moulding of entirety is also more convenient.Certainly, except the tracheae 5 in this example mates with described body 1 inwall, also can tracheae 5 be directly injection-moulded in the material of body, only be located at described body 1 by outside outlet 51 and entrance 52.
In the present invention, no matter be the air flue 4 be set directly on body 1, still take shape in the tracheae 5 on body, be not all communicated with the empty internal of puncturing lever body, therefore the present invention does not just need the seal of the extra empty internal for sealing puncturing lever body, and therefore structure can be simple.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
