SCOPE WARMING DEVICE

摘要

A warming device (30) for warming the lens portion (2) of an optical instrument (I), such as a laparoscope, to a temperature above ambient to prevent lens fogging comprising: a double walled cylindrical tube (3) having an intemal wall (3b), and an external wall (3a), an upper surface and an open distal portion (7) with a central cavity (4) therebetween; a protrusion (9) extending from said upper surface, sized and shaped to receive the lens portion; a circular cap (5) sized to attach to said distal portion of said double walled cylindrical tube; and, a heating element (15) enclosed within said central cavity and thermally coupled to said insulation layer.

1. A warming device which warms a distal portion of an optical instrument, the warming device comprising:
a double walled cylindrical tube having an internal wall, an external wall, a proximal end, an open distal portion, and a central cavity formed inward in relation to the internal wall; a protrusion extending from the proximal end into the central cavity, the protrusion sized and shaped to receive a lens portion of the optical instrument; a circular cap sized to attach to the distal portion of the double walled cylindrical tube; an insulation layer between the internal wall and the external wall; and a heating element enclosed within the central cavity.
