DEVICES AND METHODS FOR WARMING AND CLEANING LENSES OF OPTICAL SURGICAL INSTRUMENTS

摘要

A lens warming and cleaning device (110, 210, 310, 410) is used to warm and clean the lens (14) and/or distal portion (16) of an optical instrument such as a laparoscope (10). The warming and cleaning device includes a heat conducting tube (114, 214, 314, 414) sized and shaped to receive the lens of the optical instrument, a heating pad (120, 220, 320, 420) thermally coupled to an exterior of the tube, and a cleaning member in the form of a sponge (116, 216, 316, 416) disposed within the tube such that when the lens of the optical instrument is inserted into the tube, the lens contacts the sponge. A moistening mechanism in the form of a squeeze bottle (118, 418) containing a saline solution can be in contact with the sponge so that a surgeon can squeeze the bottle to moisten the sponge.
