Abstract

Various embodiments are generally directed to devices, systems, and methods for controlling the flow of fluids in endoscopic systems, such as endoscopic ultrasound (EUS) endoscopes. Some embodiments are particularly directed to valve sets and/or valve interface mechanisms for controlling air, water, and/or suction flow through a valve well for an endoscopic system. Several embodiments are directed to user interface mechanisms and techniques for enabling an operator to interact with and control endoscope valves. Many embodiments are directed to mechanisms and techniques for translating interface input motion into valve control motions. In one or more embodiments, the valve sets and/or valve interface mechanisms may be disposable.

First claim

What is claimed is:

1. A medical device, comprising:
a valve well comprising a suction channel, a working channel, a balloon channel, and an atmospheric channel;
a suction valve set including a working channel valve, a balloon valve, and an atmospheric valve, the working channel valve configured to control flow through the working channel of the valve well, the balloon valve configured to control flow through the balloon channel of the valve well, and the atmospheric valve configured to control flow through the atmospheric channel of the valve well,
a valve interface mechanism including a set of one or more biasing members and a user interface mechanism, the user interface mechanism operable between a first state, a second state, and a third state, the first state comprising the suction valve set configured to place a suction channel of the valve well in fluid communication with the atmospheric channel, the second state comprising the suction valve set configured to place the suction channel in fluid communication with the working channel, and the third state comprising the suction valve set configured to place the suction channel in fluid communication with the balloon channel, wherein in the first state the working channel valve blocks flow through the working channel, the balloon valve blocks flow through the balloon channel, and the atmospheric valve permits flow through the atmospheric channel, wherein in the second state the working channel valve permits flow through the working channel, the balloon valve blocks flow through the balloon channel, and the atmospheric valve blocks flow through the atmospheric channel,
wherein in the third state the working channel valve blocks flow through the working channel, the balloon valve permits flow through the balloon channel, and the atmospheric valve blocks flow through the atmospheric channel, and
wherein the user interface mechanism comprises a lever coupled with the atmospheric valve and one or more linkages, the lever is configured to receive input causing the lever to pivot and the atmospheric valve to adjust to operate the user interface mechanism between the first state, the second state, and the third state.

2. The medical device of claim 1 , wherein a transition from the first state to the second state produces tactile feedback via the lever.

3. The medical device of claim 1 , wherein a transition from the second state to the third state produces tactile feedback via the lever.

4. A method of configuring the medical device of claim 1 , comprising:
configuring the suction valve set to place the suction channel of the valve well in fluid communication with the atmospheric channel of the valve well based on operation of the user interface mechanism to the first state;
configuring the suction valve set to place the suction channel of the valve well in fluid communication with the working channel of the valve well based on operation of the user interface mechanism to the second state; and
configuring the suction valve set to place the suction channel of the valve well in fluid communication with the balloon channel of the valve well based on operation of the user interface mechanism to the third state.

5. The method of claim 4 , comprising producing tactile feedback via the user interface mechanism in response to operation of the user interface mechanism to one or more of the first state, the second state, and the third state.
