20220090996 · 2022-03-24 ·

A histologic tissue sample support device includes a tissue cassette a frame, and a lid. The tissue cassette has a recess including a body with at least one side wall and a bottom wall and is formed of material that can be successfully sectioned in a microtome and is resistant to degradation from solvents and chemicals used to fix, process and stain tissue. The tissue cassette is movably coupled to the frame. The lid is separably coupled to a peripheral portion of the frame. When the lid is separated from the peripheral portion, the lid and the tissue cassette are capable of moving from a first position to a second position with respect to the frame, and in the second position the bottom wall and at least a portion of the side wall extend beyond a bottom edge of the frame for sectioning in the microtome.

AUTOMATED TISSUE SECTION TRANSFER SYSTEM WITH HIGH THROUGHPUT

There is provided an automated system for preparing tissue samples that comprises one or more microtomes, a hydration system, and a processor, the processor being programmed to initiate facing, by one or more microtomes, of a first tissue block comprising a first tissue sample embedded in an embedding material, and cause the first tissue block to be hydrated by the hydration system for a first predetermined time, and initiate facing, by one or more microtomes, of a second tissue block while the first tissue block is being hydrated, the second tissue block comprising a second tissue sample embedded in an embedding material, and cause the second tissue block to be hydrated by the hydration system for a second predetermined time, and to initiate the one or more microtomes to begin sectioning of the first tissue block while the second tissue block is being hydrated.

Enhanced Hydration Methods and Systems for Histology

There is provided a histology system that comprises a microtome configured to expose a face of a tissue block comprising a tissue sample embedded in an embedding material and remove one or more tissue sections from the sample, a hydration system configured to hydrate the tissue block by depositing a hydrating liquid on the face of the tissue block, and a transfer system configured to transfer the one or more tissue sections from the microtome to one or more slides. In some embodiments, the hydration system is configured to produce droplet condensation of the hydrating liquid and deposit the condensation on the face of the tissue block.

AUTOMATED SPECIMEN PROCESSING SYSTEMS AND METHODS

The disclosure presents systems and methods for processing a specimen slide using a specimen processing system. Specimen slides may sequentially be ejected from a slide carrier towards a label reader to determine an appropriate processing protocol for the slides. A cracking element may be engaged with the slide carrier prior to ejecting the slide, in order to break or “crack” any residual adhesive bond between edges of a slide and walls of the carrier. The specimen slides may be horizontally aligned and resting on a corresponding plurality of flat shelves, enabling even spacing via gravitational forces. The slides are therefore evenly spaced, enabling damage-free ejection of slides, and proper positioning for additional operations including scanning, viewing, heating, washing, and other processing. The label reader may process scanned information from the label of the slide to determine one or more attributes of the slide, and to generate an order or sequence of operations to be thereafter performed on the slide.

MODULE FOR FREEZING AND STORAGE OF FROZEN TISSUE

An article comprising:

a planar base having a first surface and an opposing second surface and an outer peripheral edge, wherein the second surface includes an area comprising a plurality of protuberances and configured to attach and maintain orientation of a frozen tissue specimen block; and

a removable lid having a first side and a second side, wherein the first side defines a continuous planar surface and the second side defines a recessed portion configured to cover a frozen tissue specimen block and an outer rim configured to engage with the outer peripheral edge of the base, wherein the outer rim does not form part of the recessed portion,

wherein the area of the base and the recessed portion of the lid are aligned.

Microtome with generator

A sample sectioning device including a cutting mechanism that is operable to cut sections from a sample, a sample holder operable to move relative to the cutting mechanism, the sample holder having a first side and a second side, the first side faces the cutting mechanism and is dimensioned to receive a sample, a light source coupled to the sample holder, wherein the light source is operable to emit a light from the first side of the sample holder and through a sample positioned on the first side, and a generator operable to generate an electrical energy for providing power to the light source.

Transporter systems, assemblies and associated methods for transporting tissue samples

A tissue sample that has been removed from a subject can be properly fixed for evaluation using the disclosed transporter assembly for carrying a tissue sample and method for fixing an unfixed tissue sample. In one embodiment, the disclosed assembly includes a transport container, a fixative in the transport container, and a cooling device that reduces and/or maintains the temperature of the fixative to perform a pre-soaking process at a temperature of less than about 7° C. The pre-soaking process can, for example, be performed during sample transport or during extended periods of storage, such as over a weekend.
