Abstract
A device for containing and measuring a biological tissue specimen includes a tissue cassette with a ruler or metric device etched, printed, embossed, or designed into the cassette body. The device facilitates the measuring of a tissue specimen accurately, while reducing fatigue or contamination of the tissue sample.
Core Innovation
The invention provides a cassette for holding and measuring a tissue sample. The cassette includes a body with a bottom wall having an upper surface and at least one side wall extending upwardly to define an interior space for receiving the tissue sample, together with a plurality of cassette notches spaced apart along an upper surface of the at least one side wall and a lid adapted to cover the body and be secured thereto in a closed position.
In the closed position, a plurality of lid notches spaced apart along an edge of the lid align with the cassette notches to define a plurality of successively larger spans. These aligned notches are used to measure one or more diametric dimensions of the tissue sample, and a ruler is built into the body to measure one or more linear dimensions of the tissue sample.
The described cassette integrates a built-in metric ruler into the cassette body and/or lid using etched, printed, or embossed designs. The cassette design includes horizontal and vertical rulers, and aligned lid/cassette notch patterns to measure tissue diameters with optional additional rulers.
Claims Coverage
The partial content identifies one independent claim that covers a tissue-sample cassette integrating a built-in ruler within the body and a lid/notch alignment structure for measuring successively larger spans to obtain diametric dimensions. The claim set further includes dependent refinements that specify ruler configurations and additional structural features.
A cassette for holding and measuring with built-in body ruler and aligned lid/cassette notches
A cassette for holding and measuring a tissue sample, comprising a body including a bottom wall having an upper surface and at least one side wall extending upwardly to define an interior space for receiving the tissue sample, a plurality of cassette notches spaced apart along an upper surface of the at least one side wall, a lid adapted to cover the body and be secured thereto in a closed position, a plurality of lid notches spaced apart along an edge of the lid, and a ruler within the body to measure one or more linear dimensions of the tissue sample, the ruler being built into the body, wherein the pluralities of notches align in the closed position to define a plurality of successively larger spans to measure one or more diametric dimensions of the tissue sample.
The claim coverage centers on a tissue cassette that measures diametric dimensions via aligned successively larger lid and side-wall notch spans, and measures linear dimensions via a ruler built into the body. Dependent refinements further specify ruler structures and arrangements, including horizontal and vertical rulers and embossed implementation, along with optional body features such as perforations.
