Abstract
Claims
1. An endoscopic biopsy valve, comprising: A body having an instrument channel, one end of which is configured to connect to a working channel interface of an endoscope; a cover for covering the other end of the instrument channel, the cover having a slit extending through its thickness for a medical instrument to pass through; a fastener having a sleeve hole for fitting onto the working channel interface; a first connecting strap connecting the two ends of the body and the cover respectively; and a second connecting strap, one end of the second connecting strap connecting to the body or the cover, the other end of the second connecting strap connecting to the fastener.
2. The endoscopic biopsy valve as described in claim 1, wherein, One end of the first connecting strip is connected to the outer surface of the body, and the other end of the first connecting strip is connected to the side edge of the cover.
3. The endoscopic biopsy valve as described in claim 1, wherein, The first connecting strip and the second connecting strip are integrally formed and connected to the side edge of the cover, and the connection point of the first connecting strip and the cover is adjacent to the connection point of the second connecting strip and the cover.
4. The endoscopic biopsy valve as described in claim 1, wherein, When not subjected to external force, the first connecting strip and the second connecting strip have an included angle between them, and the included angle is between 20 and 90 degrees or between 90 and 180 degrees.
5. The endoscopic biopsy valve as described in claim 1, wherein, The cross-sectional width of the first connecting strip is greater than the cross-sectional width of the second connecting strip.
6. The endoscopic biopsy valve as described in claim 1, wherein, The length of the first connecting strip is less than the length of the second connecting strip.
7. The endoscopic biopsy valve as described in claim 1, wherein, One end of the main body is provided with an annular flange that extends horizontally outward from the periphery of the end to guide the cover to close.
8. The endoscopic biopsy valve as claimed in claim 1, wherein, The inner surface of the body is provided with internal threads to form a spiral engagement seal with the working channel interface.
9. The endoscopic biopsy valve as claimed in claim 1, wherein, The slit extends through the thickness of the cover, forming an elastic valve.
10. The endoscopic biopsy valve as claimed in claim 1, wherein, The cover includes a top cover and a plug, the plug being disposed on one side of the top cover and used to be inserted into an opening at one end of the body.
11. The endoscopic biopsy valve as claimed in claim 10, wherein, The slit is positioned across the center of the top cover.
12. The endoscopic biopsy valve as claimed in claim 1, wherein, One end of the second connecting strip is attached to the outer surface of the body.
13. The endoscopic biopsy valve as claimed in claim 1, wherein, The endoscopic biopsy valve is made of a single injection molding process using an elastic material.
