Abstract
Devices and methods for yielding lymph nodes from fatty tissue, the device including a fenestrated sample chamber configured to receive a sample of fatty tissue having lymph nodes; a lockable gate switchable between a closed position that is locked and an open position; a pusher configured to push the sample against the gate when locked in the closed position to compress the tissue, and configured to push the compressed tissue out of the sample chamber when the gate is subsequently opened; and a cutting chamber aligned distal to the sample chamber for receiving compressed tissue from the sample chamber, the cutting chamber comprising sets of opposing through slots aligned to permit slicing of the compressed tissue into sections, thereby yielding lymph nodes from the fatty tissue.
Claims18
A device for collecting lymph nodes from fatty tissue, the device comprising:
- a) a fenestrated sample chamber comprising a plurality of throughbores arranged to elute fluid from the sample chamber, the sample chamber configured to receive a sample of fatty tissue comprising lymph nodes;
- b) a lockable gate switchable between a closed position that is locked and an open position;
- c) a pusher configured to push the sample against the gate when locked in the closed position to more densely pack the tissue and configured to push the packed tissue out of the sample chamber when the gate is subsequently opened;
- and
- d) a cutting chamber aligned distal to the sample chamber for receiving the packed tissue from the sample chamber, the cutting chamber comprising sets of opposing through slots aligned to permit slicing of the packed tissue into sections, thereby collecting the lymph nodes from the fatty tissue.
A device for collecting lymph nodes from fatty tissue, the device comprising:
- a) a fenestrated sample chamber comprising a plurality of throughbores arranged to elute fluid from the sample chamber, the sample chamber configured to receive a sample of fatty tissue comprising lymph nodes;
- b) a lockable gate switchable between a closed position that is locked and an open position;
- c) a pusher configured to push the sample against the gate when locked in the closed position to more densely pack the tissue and configured to push the packed tissue out of the sample chamber when the gate is subsequently opened;
- and
- d) a wheel spaced distal to the sample chamber to form a cutting space and configured for rotation around a longitudinal axis of the sample chamber, the wheel comprising one or more receiving ports rotationally aligned to receive the packed tissue from the sample chamber in series.
A method of sectioning tissue for histology cassettes, the method comprising:
- a) providing a device for collecting lymph nodes from fatty tissue, the device comprising:
- a fenestrated sample chamber comprising a plurality of throughbores arranged to elute fluid from the sample chamber, the sample chamber configured to receive a sample of fatty tissue comprising lymph nodes,
- a lockable gate switchable between a closed position that is locked and an open position, thereby closing and opening the sample chamber at the gate, and
- a pusher configured to push the sample against the gate when locked in the closed position to more densely pack the tissue and configured to push the packed tissue out of the sample chamber when the gate is subsequently opened;
- b) adding a sample of fatty tissue comprising lymph nodes to the sample chamber;
- c) locking the gate in the closed position;
- d) pushing the fatty tissue with the pusher to elute fluid through the throughbores and to pack the tissue;
- e) opening the gate;
- f) pushing the packed tissue from the sample chamber;
- and
- g) cutting the packed tissue to form a plurality of packed tissue sections sized for placement in histology cassettes.
