Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1-Fig. 3, disposable percutaneous nephrolithy visually expands sheath, including tears sheath 100 and be set to tearing sheath Expansion pipe 200 in 100, expansion pipe 200 are cylindrical shape, and front end is circular cone, and the top of circular cone is circular flat 230, expansion pipe Optical-fibre channel 210 and silk guide passage 220 are provided in 200.Wherein optical-fibre channel 210 can be by optical fiber and water filling, and seal wire is logical Road 220 can pass through seal wire.Optical-fibre channel 210 and silk guide passage 220 are arranged in parallel with expansion pipe 200, and optical-fibre channel 210 It is pierced by from circular flat 230 with silk guide passage 220.
In the present invention, the cross-sectional shape of optical-fibre channel 210 is semicircle, ellipse or triangle, works as optical fiber When the cross-sectional shape in channel 210 is triangle, three angles of triangle are fillet;The cross-sectional shape of silk guide passage 220 is It is round.The considerations of setting semicircle, ellipse or triangle for the cross-sectional shape of optical-fibre channel 210 is due in this reality With novel middle optical-fibre channel 210 and all concentrated settings of silk guide passage 220 on circular flat 230, while it being limited to whole expansion again The diameter of pipe 200 is opened, after only flattening the cross section of optical-fibre channel 210, is convenient for optical-fibre channel 210 and silk guide passage 220 are all pierced by from circular flat 230.
It further include tearing sheath connector 300 and expansion pipe fitting 400, tearing sheath connector 300 is connect with tearing sheath 100, is torn It uses the technique that heat is melted or glue is Nian Jie to be attached between sheath connector 300 and tearing sheath 100, and tears 300 He of sheath connector Tearing sheath 100 is set in expansion 200 outer wall of pipe;Expansion pipe fitting 400 is connect with expansion pipe 200, expansion pipe fitting 400 and tearing Sheath connector 300 connects.It further include for connecting expansion pipe fitting 400 and tearing the connector 500 of sheath connector 300, connector 500 Both ends be detachably connected respectively with expansion pipe fitting 400 and tearing sheath connector 300, the mode of connection can be to pass through buckle Mode, can also be by way of interference fit.
It expands pipe fitting 400 and includes three cavities, respectively seal wire cavity 410, optical fiber cavity 420 and fluid injection cavity 430, Optical fiber cavity 420 and fluid injection cavity 430 are connected to optical-fibre channel 210, and seal wire cavity 410 is connected to silk guide passage 220.
Attraction channel 310 is provided on tearing sheath connector 300.And it is logical there are two attracting to tear setting on sheath connector 300 Road 310, one of attraction channel 310 are through-hole, another attraction channel 320 is blind way, and two attraction channels 310 are right Claim setting.
Referring to Fig. 4, it is provided with step 610 on the inner wall of seal wire cavity 410 and optical fiber cavity 420, is provided on outer wall External screw thread 620 further includes locked joints 630 and locked cock 640, and locked cock 640 is set at step 610, the inner wall of locked joints 630 On be provided with internal screw thread 650 corresponding with the external screw thread 620 on 420 outer wall of seal wire cavity 410 and optical fiber cavity, and lock The inner wall of connector 630 is additionally provided with a circle and squeezes circle 660, and the top for squeezing circle 660 is contacted with locked cock 640, by that will lock To determine connector 630 and is installed to seal wire cavity 410 and optical fiber cavity 420, twisting screw thread to squeeze 660 extruding locked cock 640 of circle, so that Deformation occurs for locked cock 640, thus seal wire and optical fiber that locking is passed through from locked cock 640.
In operation, optical fiber and seal wire are passed through into optical fiber cavity 420 respectively and seal wire cavity 410 enters optical-fibre channel 210 With silk guide passage 220, final seal wire stretches out the top of silk guide passage 220, and optical fiber is flushed with the top of optical-fibre channel 210.So Expansion pipe 200 expands puncturing hole afterwards, and due to there is the presence of optical fiber, what operator can will be apparent that sees expansion pipe 200 Advanced positions can be filled the water by fluid injection cavity 430 if it find that the optical fiber front end visual field is unclear, when expansion pipe 200 The case where after reaching in renal plevis, halting, not will cause degree of puncturing through thus or pierce through kidney appearance.Then sheath will be torn It stays in puncturing hole, while expansion pipe fitting 400 being removed from tearing sheath connector 300, then extract expansion pipe 200.It Subsequent procedures instrument is connect on tearing sheath 300 afterwards.
The beneficial effects of the utility model are: visible image can be applied when carrying out dilated penetration using visual expansion sheath System prevents routine operation and punctures through pursuit of advanced studies into malpractices such as nephrorrhagias effectively to expansion positioning is punctured.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted Protection scope is asked to be defined by appended claims and its equivalent.
