Abstract
A disposable air and water (AW) valve assembly and suction valve assembly for an EUS instrument. The AW assembly includes an AW valve and an endcap for receiving the AW valve therebetween. The AW valve includes an AW stem connected to a valve stem. The suction valve assembly includes a suction valve disposed in a suction endcap. The suction valve also includes a valve stem. The valve stem is disposed between a suction valve opening such that portions of the valve stem extend beyond opposed ends of the suction endcap. The suction valve is formed from a suction stem and a piston connected to the suction stem.
Claims20
An endoscopy valve assembly comprising:
- an endcap having a first endcap opening;
- a suction valve at least partially disposed between the first endcap opening, wherein the suction valve includes a suction valve opening;
- and
- a valve stem at least partially disposed between the suction valve opening such that portions of the valve stem extend beyond opposed ends of the endcap;
- wherein the suction valve includes a suction stem having an elongated suction stem part that extends from a first side of the suction stem beyond one end of the endcap and a piston connected to a second side of the suction stem opposite the first side;
- and
- wherein the suction stem and the piston are each formed of a single piece construction.
An endoscopy valve assembly comprising:
- an endcap having a guide member defining a guide opening extending through the guide member;
- a first stem having a stem body with a first side, a second side opposite the first side, and a connection port extending from the first side of the body;
- and
- a second stem having a body with a first end and a second end, a threaded portion disposed near the first end, and a channel extending into the second end of the body, the body defining an opening extending laterally from an outer surface of the body into the channel and a clocking area disposed near the threaded portion and having a profile corresponding to a shape of the guide opening;
- and
- a piston defining an opening and having a connecting means configured to be at least partially received in the connection port;
- wherein the second stem extends through the opening of the piston and the guide opening of the endcap when the valve assembly is assembled.
A suction valve for use with an endoscope, the suction valve comprising:
- an endcap having a guide member defining a guide opening extending through the guide member;
- a first stem having a connecting port extending from a first side of a body and a distal projection extending from a second side of the body;
- a second stem having a proximal portion and a distal portion defining a channel, the proximal portion being operably inserted through the guide opening of the guide member, the proximal portion having a cross section along a length of the proximal portion corresponding to a shape of the guide opening;
- and
- a piston defining an opening and having a connecting means, the opening being configured to receive a portion of the second stem therethrough and the connecting means being operably connected to the connecting port of the first stem through a wall opening in the endcap.
