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 support assembly that stabilizes a surgical scope. The support assembly may include a first support that elevates scope optics above the liquid bath within the basin, and a second support that positions the shaft of the scope within the liquid bath, but above the floor and away from the walls of the basin. The scope optics resides outside of the bath in a dry state, while the remaining scope portions are positioned within the bath so the portions can be thermally treated. The support assembly enables a user to warm selected portions of the scope, while protecting the scope, the basin, and/or a drape lining the basin from damage caused when the scope contacts the basin.

15. The thermal treatment system of claim 14, wherein the first and second supports maintain the optics unit in a dry state by positioning the scope distal portion in the sterile medium and elevating the scope optics unit above the sterile medium.

16. The thermal treatment system of claim 1, further comprising a drape disposed over the thermal treatment system and recessed within said basin to form a drape receptacle for said sterile medium.

17. The thermal treatment system of claim 16, wherein the first and second supports are disposed above the drape.

18. The thermal treatment system of claim 16, wherein the first and second supports are disposed below the drape.

19. The thermal treatment system of claim 16, wherein the first and second supports are formed integral with the drape.

20. The thermal treatment system of claim 16, wherein the drape includes sensors to detect at least one of the presence of a liquid within the basin, the absence of a liquid within the basin, or the presence of a drape leak.

21. In a thermal treatment system including a housing with a top surface, a basin recessed into said top surface including a floor and configured to contain a sterile medium, a first support disposed to rest at least partially on the housing top surface and having a portion defining at least one upper receptacle positioned within said basin and above said sterile medium, a second support disposed within said basin and having a portion defining at least one lower receptacle positioned at least partially below the surface of the sterile medium, a method of selectively thermally treating medical instrument portions comprising:
