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.

Claims

1. In a thermal treatment system including a housing with a top surface and a basin recessed within said housing top surface to contain and thermally treat a sterile medium, a rack for supporting objects in the form of medical instruments within said basin comprising:

an elongated bar member including;

a first end portion configured to engage said housing;

a second end portion configured to engage said housing; and

an intermediate portion between said first and second end portions and including a plurality of serpentine sections defined within said intermediate portion of said elongated bar member, wherein each serpentine section includes a recess to form a corresponding receptacle supported by said bar member above a basin floor and within an upper portion of said basin, and wherein each receptacle is configured to removably engage and elevate a portion of a corresponding object above the basin floor and said sterile medium to maintain the elevated portion in a dry state.

2. The rack of claim 1, wherein each of said end portions includes a generally U-shaped engagement member configured to engage said housing top surface.

3. The rack of claim 1, wherein said intermediate portion includes a series of alternating peaks and recesses to form said serpentine sections.

4. The rack of claim 1, wherein at least one object includes a scope with a shaft and an optics unit.

5. The rack of claim 4, wherein a receptacle of said intermediate portion includes dimensions greater than said shaft and less than said optics unit to receive said shaft and secure said scope within that receptacle.
