Abstract
A cleaning device (100) enables cleaning of a lens (18) of an endoscope (10) during a surgical procedure to maintain a clear image without having to remove the endoscope (10) from the patient's body. The cleaning device (100) includes a suction ring (500) that selectively encloses the lens (18) of the endoscope (10) and retains the cleaning fluid during cleaning of the lens (18).
Claims20
A cleaning device for use with an endoscope comprising:
- a housing detachably securing the endoscope thereto, the housing including an inlet port, an outlet port, and a slider slidably received in the housing;
- an elongate shaft extending distally from the housing, the elongate shaft defining a lumen in communication with the housing, the elongate shaft coupled to the slider for concomitant axial displacement therewith;
- an inner tube disposed within the lumen of the elongate shaft, the inner tube receiving the endoscope;
- and
- a suction ring coupled to a distal end portion of the elongate shaft, the slider transitionable between a first position, in which, the slider closes the inlet and outlet ports and a lens of the endoscope is distal of the suction ring, and a second position, in which, the slider is in communication with the inlet port to provide a cleaning fluid to the lens of the endoscope enclosed by the suction ring.
2 more elements
A method of cleaning an endoscope comprising:
- placing an endoscope in a cleaning device such that a lens of the endoscope is disposed distal of a suction ring mounted on a distal end portion of an elongate shaft of the cleaning device;
- securing the endoscope to a housing of the cleaning device to inhibit relative movement between the housing and the endoscope;
- transitioning a slider disposed in the housing from a first position, in which, the slider closes inlet and outlet ports of the housing, to a second position, in which, the slider is in fluid communication with the inlet and outlet ports and the elongate shaft is advanced to enclose the lens of the endoscope by the suction ring;
- supplying a cleaning fluid to the lens of the endoscope to remove debris from the lens while retaining the cleaning fluid within the suction ring;
- and
- removing the cleaning fluid from the suction ring through the outlet port.

A method of cleaning an endoscope comprising:
- placing a portion of an endoscope in a cleaning device such that a lens of the endoscope is disposed distal of a suction ring mounted on a distal end portion of the cleaning device;
- axially displacing an elongate shaft of the cleaning device to place the lens of the endoscope within the suction ring;
- applying suction to the suction ring to close an opening defined by the suction ring to form a fluid tight seal;
- applying a cleaning fluid to the lens of the endoscope to remove debris from the lens while retaining the cleaning fluid within the suction ring;
- and
- removing the cleaning fluid from the suction ring through an outlet port of a housing of the cleaning device.
