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.

Claims (39)

1. A thermal treatment system for thermally treating an object comprising:

a housing including a top surface;

a basin recessed into said top surface and configured to contain a sterile medium, wherein said basin comprises a floor;

a thermal unit to thermally treat said basin and said sterile medium;

a first support disposed within said basin positioned at least partially above said sterile medium; and

a second support disposed within said basin at least partially below the surface of the sterile medium, wherein the second support comprises a block with at least one receptacle configured to receive a portion of the object, and wherein the first support and second support are operable to support the object within the basin such that a portion of the object is elevated above the surface of the sterile medium to maintain that portion in a dry state.

2. The thermal treatment system of claim 1 , wherein the receptacle is formed by a bore extending through the block.

3. The thermal treatment system of claim 1 , wherein the object includes a surgical scope with a distal portion and a proximal portion including an optics unit.

4. The thermal treatment system of claim 3 , 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.

5. 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.

6. The thermal treatment system of claim 5 , wherein the first and second supports are disposed above the drape.

7. The thermal treatment system of claim 5 , wherein the first and second supports are formed integral with the drape.

8. The thermal treatment system of claim 1 , wherein the second support elevates another portion of the object above the basin floor and within the sterile medium.

9. The thermal treatment system of claim 1 , wherein the first support comprises a rack including a first end portion, a second end portion, and an intermediate portion defining at least one receptacle to support the object.

10. The thermal treatment system of claim 9 , wherein the intermediate portion of the first support comprises a series of alternating recesses and peaks, and wherein the recesses define a series of receptacles.

11. The thermal treatment system of claim 9 , wherein each of the end portions of the first support comprise an engagement member configured to engage the housing top surface and position the first support proximate the housing top surface.

12. A thermal treatment system for thermally treating an object comprising:

a housing including a top surface;

a basin recessed into said top surface and configured to contain a sterile medium, wherein said basin comprises a floor;

a drape disposed over the thermal treatment system and recessed within said basin to form a drape receptacle for said sterile medium;

a thermal unit to thermally treat said basin and said sterile medium;

a first support disposed within said basin positioned at least partially above said sterile medium; and

a second support disposed within said basin at least partially below the surface of the sterile medium, wherein the first and second supports are disposed below the drape and operable to support the object within the basin such that a portion of the object is elevated above the surface of the sterile medium to maintain that portion in a dry state.

13. A thermal treatment system for thermally treating an object comprising:

a housing including a top surface;

a basin recessed into said top surface and configured to contain a sterile medium, wherein said basin comprises a floor;

a drape disposed over the thermal treatment system and recessed within said basin to form a drape receptacle for said sterile medium, 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;

a thermal unit to thermally treat said basin and said sterile medium;

a first support disposed within said basin positioned at least partially above said sterile medium; and

a second support disposed within said basin at least partially below the surface of the sterile medium, wherein the first and second supports are operable to support the object within the basin such that a portion of the object is elevated above the surface of the sterile medium to maintain that portion in a dry state.

14. A surgical drape for use in a thermal treatment system including a housing with a top surface and a basin recessed within the housing top surface to contain and thermally treat a sterile medium, the basin including a floor, said drape comprising:

a drape adapted to cover and hang down from the top surface of the housing, the drape being disposed within and conforming to the basin to form a drape receptacle;

a first support disposed within the drape receptacle operable to support a first portion of an object above the surface of the sterile medium to maintain the first object portion in a dry state, wherein the first support is in the form of a rack comprising a first end portion configured to engage said housing; a second end portion configured to engage the housing; and an intermediate portion including at least one receptacle configured to removably receive the object; and

a second support disposed within the drape receptacle operable to support a second portion of the object below the surface of the sterile medium and above the floor of the basin, wherein the second support comprises a block including a receptacle formed by a channel extending through the block.

15. The drape of claim 14 , wherein the object includes a scope with an optics unit.

16. A surgical drape for use in a thermal treatment system including a housing with a top surface and a basin recessed within the housing top surface to contain and thermally treat a sterile medium, the basin including a floor, said drape comprising:

a drape adapted to cover and hang down from the top surface of the housing, the drape being disposed within and conforming to the basin to form a drape receptacle, wherein the drape further 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;

a first support disposed within the drape receptacle operable to support a first portion of an object above the surface of the sterile medium to maintain the first object portion in a dry state; and

a second support disposed within the drape receptacle operable to support a second portion of the object below the surface of the sterile medium and above the floor of the basin.
