CA 2400381

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.

L'invention concerne un dispositif de chauffage et de nettoyage de lentilles (110, 210, 310, 410) utilisé pour chauffer et pour nettoyer une lentille (14) et/ou la partie distale (16) d'un instrument optique, tel qu'un laparoscope (10). Ce dispositif de chauffage et de nettoyage comprend un tube thermoconducteur (114, 214, 314, 414) présentant une dimension et une forme permettant de loger la lentille de l'instrument optique dans le tube, un coussin chauffant (120, 220, 320, 420) couplé thermiquement à l'extérieur du tube, et un élément de nettoyage sous forme d'une éponge (116, 216, 316, 416) située dans le tube. Ainsi, lorsque la lentille de l'instrument optique est insérée dans le tube, celle-ci entre en contact avec l'éponge. Un mécanisme d'humidification sous forme d'une pissette (118, 418) contenant une solution saline peut être mise en contact avec l'éponge afin que le chirurgien puisse presser la pissette pour humidifier l'éponge.
