Abstract

A thermal treatment system for thermally treating objects includes a housing including a top surface, a basin recessed into the top surface and configured to contain a liquid medium, where the liquid medium thermally treats objects placed within the liquid medium, and a ramp structure disposed on the top surface of the housing. The ramp structure is configured to support at least one object such that a first end portion of the object is disposed within the liquid medium while a second end portion of the object is supported by the ramp structure outside of the liquid medium.

2. The system of claim 1, wherein the ramp structure comprises a base that secures to the top surface and a ramp that secures to the base.

3. The system of claim 2, wherein the ramp is removably secured to the base with magnets.

4. The system of claim 2, wherein the ramp is removably secured to the base via a tab disposed on one of the ramp and the base that engages with a corresponding groove disposed on the other of the ramp and the base.

5. The system of claim 1, wherein the ramp structure includes an upper receiving surface that is angled and is configured to receive and retain a plurality of objects such that a first end portion of each object is disposed within the liquid medium while a second end portion of each object is supported by the upper receiving surface of the ramp structure outside of the liquid medium.

6. The system of claim 5, wherein the upper receiving surface includes at least one concave surface configured to hold and retain the second end portion of a first object and at least one planar surface configured to hold and retain the second end portion of a second object.

7. The system of claim 1, further comprising a drape disposed over at least a portion of the thermal treatment system and recessed within the basin to form a drape receptacle for the liquid medium.

8. The system of claim 7, wherein the drape covers at least a portion of the ramp structure.

9. The system of claim 7, wherein the ramp structure is affixed to the drape.

10. The system of claim 1, further comprising a tray suitably dimensioned to be removably disposed within the basin such that at least a portion of the liquid medium and the first end portion of each object are disposed within a reservoir of the tray.

11. The system of claim 10, wherein a bottom wall of the tray is ramped between two longitudinal end walls of the tray so as to form a gap between the tray and the bottom wall of the tray, the gap changing in dimension between the longitudinal end walls of the tray.

12. The system of claim 10, wherein the tray includes at least one of:

(a) a plurality of grooves along an interior bottom wall surface of the tray, wherein the grooves provide a frictional, non-smooth contour for the interior bottom wall surface to enhance stabilization of the first end portion of each object disposed within the tray reservoir; and

(b) at least one hole extending through the bottom wall surface of the tray to facilitate a flow and circulation of liquid medium between the tray reservoir and a gap formed between a bottom wall surface of the basin and the interior bottom wall surface of the tray.

13. The system of claim 10, wherein the tray includes a top wall that is secured with the tray and movable between first and second positions in relation to a top edge portion of the tray so as to partially cover an opening at the top edge portion of the tray when the top wall is in the first position and to not cover any portion of the opening when the top wall is in the second position.

14. The system of claim 10, wherein the at least one object comprises a scope including a camera disposed at the second end portion of the scope, and an interior wall portion of the tray is white in color to facilitate calibration of the camera when the first end of the scope is aligned with the white interior wall portion of the tray.

15. The system of claim 1, further comprising:

a shelf defined at the top surface of the housing proximate the basin, wherein the shelf is suitably dimensioned to support components of one or more objects being thermally treated by the system.

16. A surgical drape kit 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 liquid medium, the drape kit comprising:

a drape suitably dimensioned 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; and

a ramp structure configured to be secured on the top surface of the housing, the ramp structure being configured to support at least one object such that a first end portion of the object is disposed within the liquid medium while a second end portion of the object is supported by the ramp structure outside of the liquid medium.

17. The surgical drape kit of claim 16, wherein the ramp structure comprises a base that is removably securable to the housing top surface and a ramp that secures to the base.

18. The surgical drape kit of claim 16, wherein the ramp structure includes an upper receiving surface that is angled and is configured to receive and retain a plurality of objects such that a first end portion of each object is disposed within the liquid medium while a second end portion of each object is supported by the upper receiving surface of the ramp structure outside of the liquid medium.

19. The surgical drape kit of claim 18, wherein the upper receiving surface includes at least one concave surface configured to hold and retain the second end portion of a first object and at least one planar surface configured to hold and retain the second end portion of a second object.

20. The surgical drape kit of claim 16, wherein the ramp structure is integral with the drape such that, in use, the drape underlies the ramp structure.

21. The surgical drape kit of claim 16, wherein the ramp structure is separate from the drape such that, in use, the drape covers at least a portion of the ramp structure.

22. The surgical drape kit of claim 16, further comprising a tray suitably dimensioned to be removably disposed within the basin such that at least a portion of the liquid medium and the first end portion of each object are disposed within a reservoir of the tray.

23. The surgical drape kit of claim 22, wherein a bottom wall of the tray is ramped between two longitudinal end walls of the tray so as to form a gap between the tray and the bottom wall of the tray, the gap changing in dimension between the longitudinal end walls of the tray.

24. The surgical drape kit of claim 22, wherein the tray includes at least one of:

(a) a plurality of grooves along an interior bottom wall surface of the tray, wherein the grooves provide a frictional, non-smooth contour for the interior bottom wall surface to enhance stabilization of the first end portion of each object disposed within the tray reservoir; and

(b) at least one hole extending through the bottom wall surface of the tray to facilitate a flow and circulation of liquid medium between the tray reservoir and a gap formed between a bottom wall surface of the basin and the interior bottom wall surface of the tray.

25. The surgical drape kit of claim 22, further comprising:

a shelf configured to attach with the top surface of the housing proximate the basin, wherein the shelf is suitably dimensioned to support components of one or more objects being thermally treated by the system.

26. In a thermal treatment system including a housing with a top surface, a basin recessed into the top surface and configured to contain a liquid medium, and a ramp structure disposed on the top surface of the housing, a method of selectively thermally treating objects comprising:

receiving an object within the basin such that a first end portion of the object is disposed within the liquid medium while a second end portion of the object is supported by the ramp structure outside of the liquid medium; and

thermally treating at least the first end portion of the object submerged within the liquid medium.

27. The method of claim 26, wherein the thermal treatment system further includes a drape disposed over at least a portion of the thermal treatment system and recessed within the basin to form a drape receptacle for the liquid medium, and the ramp structure is affixed to the drape.
