Abstract
A valve apparatus device provides surgical instruments with sealable access to an inlet port of an endoscope instrument channel. The valve has a hollow body with a distal end that releasably attaches to the inlet port, and a flexible diaphragm seal dividing the body into a proximal chamber and a distal chamber. An instrument opening extends through the diaphragm seal for the passage of instruments therethrough, and connects the chambers together. The diaphragm seal is configured to seal with a surgical instrument inserted into the instrument opening. At least one fluid transfer member is provided to fluidly interconnect the proximal chamber to the distal chamber when the surgical instrument is sealed within the instrument opening.
Claims21
A valve for providing a surgical instrument with scalable access to an inlet port of an endoscope instrument channel, said valve comprising:
- a hollow tubular body having a distal end of said hollow configured to removably attach to the inlet port, and a proximal end of said hollow sealed with a removable cap;
- an internal wall separating said hollow into a proximal chamber and a distal chamber;
- a sealable instrument opening having a first portion extending through said cap and a second portion extending through said wall for surgical instrument access to the inlet port through said valve;
- and
- an interconnection member providing fluid communication between said proximal and distal chambers when the surgical instrument is sealed within said portion of sealable instrument opening extending through said internal wall.
A valve for providing a surgical instrument with sealable access to an inlet port of an endoscope instrument channel, said valve comprising:
- a hollow tubular body with a distal end of said hollow configured to removably attach to the inlet port;
- a flexible diaphragm having an instrument opening extending therethrough, said flexible diaphragm positioned within said hollow to separate said hollow into a proximal chamber and a distal chamber that communicate through said instrument opening, said instrument opening further configured to seal against the surgical instrument when the instrument is inserted therein;
- and
- a pressure transfer member configured to equalize pressure between said proximal and distal chambers when said instrument opening is sealed against the surgical instrument.
A valve for providing a surgical instrument with sealable access to an inlet port of an endoscope instrument channel, said valve comprising:
- a hollow tubular body having a distal end of said hollow configured to removably attach to the inlet port;
- a flexible seal separating the hollow into a proximal chamber and a distal chamber, said flexible seal having an instrument seal opening extending therethrough between said proximal and said distal chambers;
- at least one orifice connecting to said proximal chamber and said distal chamber, wherein when the surgical instruments accesses the inlet port of the endoscope instrument channel through the valve and the surgical instruments seals with said instrument seal opening, said at least one orifice provides fluid communication between said proximal and distal chambers,
