System and method for deposition and removal of an optical element on an endoscope objective

摘要

An applicator suitable for converting a white-light endoscope into an endoscope for combined white-light/fluorescence imaging is disclosed. The applicator facilitates attachment of an optical element, for example an optical filter, to a distal optical port of an endoscope. The applicator engages with alignment feature on the endoscope's distal end and releasably supports the optical element in an opening that is aligned with the optical port. The optical element is released in a proximal direction by pressing down on an actuator.

主权项

1. A method for attaching an optical element to an optical port disposed on a distal end of an endoscope comprising one or more registration features, comprising the steps of:
providing an applicator releasably holding the optical element, said optical element having an adhesive side facing the endoscope's distal end and an opposing non-adhesive side, and said applicator comprising one or more alignment members; engaging one or more of the alignment members disposed on the applicator with the one or more corresponding registration features disposed at the endoscope's distal end, thereby aligning the optical element with the optical port, and applying with the applicator an external force against the non-adhesive side of the optical element so as to disengage the optical element from the applicator and urge the adhesive side of the optical element into contact with the optical port.
