A histologic tissue sample support device (600) includes a tissue cassette (616), a cassette feature (626), and a frame (612). The tissue cassette (616) has at least one side wall (616a) and is coupled to the cassette feature (626). The cassette feature (626) has at least one element to secure, align, orient, bias, and / or provide indicia to identify a tissue sample. The tissue cassette (616) is movably coupled to the frame (612) that has a bottom edge (612f). The tissue cassette (616) and the cassette feature (626) are capable of moving from a first position to a second position with respect to the frame (612) and, in the second position, at least a portion of the cassette feature (626) and at least a portion of the side wall (616a) extend beyond the bottom edge (612f) of the frame (612) for sectioning in the microtome.

This utility model relates to the field of laser marking technology, specifically to a material feeding assembly for a tissue box laser writer. It includes a conveyor belt and a support platform placed on one side of the conveyor belt. At least two rectangular plates are arranged inside the conveyor belt, each with a through groove at one end. Sliding strips are fixedly connected to both sides of the baffle plates. Connecting plates are fixedly connected to the upper ends of the two rectangular plates. A rectangular block is fixedly connected to one side of the connecting plate, and a housing is fixedly connected to one side of the rectangular block. A motor is fixedly connected to the inside of the housing, and a rotating wheel is fixedly connected to the output end of the motor. An eccentric shaft is provided at one end of the rotating wheel, and a waist-shaped groove is provided on the outer side of the eccentric shaft. Sliding plates are fixedly connected to both ends of the waist-shaped groove. This utility model, by controlling the forward and reverse rotation of the motor, can achieve the effect of single separation of tissue boxes of different thicknesses, improving the flexibility of separation.

Systems and methods for preparing an implant and inserting the implant intraocularly into a patient's eye, including a tissue cartridge configured to receive and hold a piece of material; a cutting device; and a delivery device. Related devices, systems, and methods are provided.

This document provides devices and methods for an automated tissue grossing system. For example, an automatic tissue grossing system can include an intake system configured to receive a specimen jar containing a tissue sample; a robotic arm comprising a gripper configured to grip the specimen jar; a decapping module comprising a stationary gripper configured to grip the specimen jar and a rotary gripper configured to rotate on a vertical axis and grip a lid of the specimen jar; and a vacuum module comprising an integrated grossing platform, wherein the grossing platform includes a slot sized to receive a cassette from the robotic arm and provide negative pressure through the slot to facilitate tissue transfer from the specimen jar to the cassette.

A method for manufacturing a histologic tissue sample support device includes molding a tissue cassette, molding a frame, and coupling the tissue cassette to the frame by assembling a frame-cassette connector. The tissue cassette has a recess including at least one side wall and a bottom wall. The tissue cassette is formed of a first 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 frame includes a bottom edge and is formed of a second material different from the first material and more rigid than the first material. The frame-cassette connector includes a first retaining structure formed integrally with the frame extending through a second retaining structure formed integrally with the cassette. The frame is capable of being decoupled from the cassette by separating the frame-cassette connector.

A histologic tissue sample support device includes a tissue cassette, a frame, and a lid. The tissue cassette has a recess including 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 lid is coupled to the frame and includes a platen configured to be received within the recess of the tissue cassette. The tissue cassette is movably coupled to the frame by a frame-cassette connector. 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 a microtome.

An apparatus including: a base; a carriage coupled to the base and projecting a distance above the base, the carriage operable to contain a mobile phone comprising a camera array in a position such that the camera array faces in a direction of the base; and a controller including machine-readable instructions operable to direct a movement of one of the carriage and the base in a direction with respect to the other along an axis. A method including: placing a mobile phone in a carriage; placing a container below the carriage, the container comprising a plurality of tissue cassettes; and capturing by the mobile phone of an image of the identifier on each of the plurality of tissue cassettes while the plurality of tissue cassettes remain in the container. Also, a machine-readable medium including instructions to cause a mobile to stitch successive captured images of identifiers into an overall image.

A cell culture apparatus for producing tissues comprises a tissue cassette, and a cell media reservoir, wherein the cell media reservoir comprises an enclosure for enclosing cell culture media, wherein the cell media reservoir has an opening for inserting the tissue cassette into the cell media enclosed in the cell media reservoir, wherein the tissue cassette has a cassette housing comprising a first main side having a first aperture covered by a first membrane, and at least one second main side having a second aperture covered by a second membrane, such that a culture chamber is formed between the first membrane and the second membrane, wherein the first membrane and the second membrane are attached to the cassette housing, wherein the tissue cassette has an injection opening extending through the cassette housing into the culture chamber for feeding cells into the culture chamber, and wherein at least one of the first membrane and the second membrane is gas-permeable.
