Abstract

A system according to the present invention includes a cabinet, a basin positioned within the cabinet to contain and thermally treat a liquid bath, and a rack or tray disposed on the cabinet that supports exposed scope optics above the liquid bath within the basin. The scope optics resides outside of the bath in a dry state, thereby permitting the remaining scope portions within the bath to be thermally treated. This enables accurate temperature warming of the scope to reduce trauma of tissue and retrieval of enhanced images by the scope during a medical procedure. The present invention permits medical personnel or operating room staff to warm scopes in a controlled environment while maintaining scope optics in a dry state.
