Abstract
The utility model discloses a kind of disposable wearing sheath of sting for thoracoscope or laparoscopic surgery, this puncture sheath comprises body, air inlet, the first unidirectional valve film and the second unidirectional valve film, air inlet is positioned at the sidepiece of body, first unidirectional valve film is positioned at the top of chamber body, second unidirectional valve film is positioned at the bottom of chamber body, and air inlet is positioned at the below of the first unidirectional valve film.Use this puncture sheath can ensure stability and the accuracy of operation technique.
Description
Technical field
This utility model relates to a kind of puncture sheath, specifically, relates to a kind of disposable wearing sheath of sting for thoracoscope or laparoscopic surgery.
Background technology
When thoracoscope, laparoscopic surgery, puncture sheath usually can be used as the passage of operating theater instruments.Existing puncture sheath comprises body, air inlet, a unidirectional valve film.When the sheath that punctures only has a unidirectional valve film, in operating process, operating theater instruments is with a valve for fulcrum, easily causes the instability of operation, is unfavorable for the accurate operation of performing the operation.
Summary of the invention
technical problem:technical problem to be solved in the utility model is: provide a kind of disposable wearing sheath of sting for thoracoscope or laparoscopic surgery, use this puncture sheath can ensure stability and the accuracy of operation technique.
technical scheme:for solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of disposable wearing sheath of sting for thoracoscope or laparoscopic surgery, this puncture sheath comprises body, air inlet, the first unidirectional valve film and the second unidirectional valve film, air inlet is positioned at the sidepiece of body, first unidirectional valve film is positioned at the top of chamber body, second unidirectional valve film is positioned at the bottom of chamber body, and air inlet is positioned at the below of the first unidirectional valve film.
Further, the first described unidirectional valve film and the second unidirectional valve film are coaxially arranged.
beneficial effect:compared with prior art, the technical solution of the utility model has the following advantages: puncture sheath of the present utility model can ensure stability and the accuracy of operation technique.Disposable wearing sheath of sting of the present utility model, comprises body, air inlet, the first unidirectional valve film and the second unidirectional valve film.First unidirectional valve film and the second unidirectional valve film are as two fulcrums of operating apparatus.When carrying out thoracoscope or laparoscopic surgery, when inserting operating apparatus, operating apparatus is simultaneously with the first unidirectional valve film and the second unidirectional valve film fulcrum as apparatus.Utilize two fulcrums, can the direction of fixing operation apparatus, add the stability of operation technique, when avoiding only having a fulcrum, apparatus easily rocks, and increases the unstability of operation technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Have in figure: body 1, air inlet 2, first unidirectional valve film 3 and the second unidirectional valve film 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of disposable wearing sheath of sting for thoracoscope or laparoscopic surgery of the present utility model, comprises body 1, air inlet 2, first unidirectional valve film 3 and the second unidirectional valve film 4.Air inlet 2 is positioned at the sidepiece of body 1, and the first unidirectional valve film 3 is positioned at the top of chamber body, and the second unidirectional valve film 4 is positioned at the bottom of chamber body.Air inlet 2 is positioned at the below of the first unidirectional valve film 3.
When carrying out thoracoscope or laparoscopic surgery, adopt the disposable wearing sheath of sting of said structure.When inserting operating apparatus, operating apparatus is simultaneously with the first unidirectional valve film 3 and the second unidirectional valve film 4 fulcrum as apparatus.Utilize two fulcrums, can the direction of fixing operation apparatus, add the stability of operation technique, when avoiding only having a fulcrum, apparatus easily rocks, and increases the unstability of operation technique.
Further, the first described unidirectional valve film 3 and the second unidirectional valve film 4 are coaxially arranged.First unidirectional valve film 3 and the second unidirectional valve film 4 are coaxially arranged, easily makes on the one hand, be conducive to the location of operating apparatus on the other hand.
