Abstract
A cleaning device enables cleaning of a lens of an endoscope during a surgical procedure to maintain a clear image without having to remove the endoscope from the patient's body. The cleaning device is mountable to an endoscope such that a wiper of the cleaning device is selectively displaced across the lens of the endoscope to remove debris from the lens.
Claims20
A surgical kit comprising:
- an endoscope having a lens at a distal end portion of the endoscope;
- and
- a cleaning device including:
- a sleeve defining a lumen dimensioned to receive the distal end portion of the endoscope;
- a lip extending radially inwards from the sleeve;
- a rib extending along a length of the sleeve, a distal portion of the rib extending over the lip, the distal portion being configured to inhibit proximal movement of the sleeve relative to the endoscope;
- and
- a frame including a supporting portion, a wiper, and an engaging portion, the supporting portion secured to the sleeve, the engaging portion pivotably coupled to the supporting portion and extending distally from the supporting portion, the engaging portion supporting the wiper for movement as a single construct,
- wherein the engaging portion and the wiper are transitionable between an aligned position and an offset position, the aligned position defined by the engaging portion and the wiper being substantially parallel to a longitudinal axis of the sleeve and the offset position defined by the engaging portion and the wiper being at an acute angle with respect to the longitudinal axis such that the wiper is displaced across the lens to remove debris from the lens.

A cleaning device for use with an endoscope comprising:
- a sleeve defining a longitudinal axis and a lumen dimensioned to receive a distal end portion of an endoscope and an opening in registration with a lens of the endoscope;
- a rib coupled to the sleeve, a distal portion of the rib extending into the lumen, the distal portion being configured to inhibit proximal movement of the sleeve relative to an endoscope disposed in the sleeve;
- and
- a frame including a supporting portion, an engaging portion pivotably coupled to the supporting portion, and a wiper, the supporting portion coupled to the sleeve, the wiper slidable across the lens of the endoscope to remove debris from the lens,
- wherein the engaging portion and the wiper are transitionable between an aligned position and an offset position, the aligned position defined by the engaging portion and the wiper being substantially parallel to the longitudinal axis and the offset position defined by the engaging portion and the wiper being at an acute angle with respect to the longitudinal axis such that the wiper is pivoted relative to the supporting portion, whereby the wiper is displaced across the lens.
