    • A dicing device dices tissue harvested from a patient. The dicing device comprises a grid cutting element and a tray to receive diced tissue. The dicing device may be integrated into an otherwise conventional biopsy device. The diced tissue specimens may be further processed, such as by being introduced into a self-expanding fistula plug creation and delivery system. The self-expanding fistula plug creation and delivery system comprises a sheet and a reinforcement tube. A scaffold material may be placed in the sheet, which may then be folded and reinforced, with the scaffold material being compressed in the sheet. The scaffold material may then be pushed into a catheter end. The catheter end may be inserted in a fistula. The scaffold material may then be flushed with a cell matrix that is based on the diced tissue to create a fistula plug, which may be left in the fistula.
    • 切割装置切割从患者收获的组织。 切割装置包括网格切割元件和用于接收切块的纸盘的托盘。 切割装置可以集成到另外常规的活检装置中。 切割的组织标本可以进一步加工,例如通过引入自膨胀瘘塞产生和递送系统。 自膨胀瘘塞产生和递送系统包括片和加强管。 支架材料可以放置在片材中,然后可以将其折叠和加强,脚手架材料被压缩在片材中。 然后将支架材料推入导管末端。 导管端可插入瘘管。 然后可以用基于切割组织的细胞基质冲洗支架材料,以产生可能留在瘘管中的瘘栓塞。

    • A biopsy device may include a needle, a cutter, and a handpiece. A vacuum pump in the handpiece may provide a vacuum to the needle and/or to the cutter. A pressure pump in the handpiece may also provide pressurized air to the needle and/or to the cutter. A motor in the handpiece may drive the vacuum pump, the pressure pump, and/or the cutter. A vacuum sensor may sense a vacuum level within the biopsy device, and cause initiation of operational cycles in response to sensed vacuum levels. Portions of a valving mechanism and a clutching mechanism may be integrally formed. A clutching and valving mechanism may be driven by a first battery-powered motor; and a cutter, pressure pump, and vacuum pump by a second battery-powered motor. A biopsy device may thus provide vacuum, pressurized air, and power from within a handpiece, such that the biopsy device is tetherless.
    • 活检装置可以包括针,切割器和手持件。 手柄中的真空泵可以向针和/或切割器提供真空。 手持件中的压力泵还可以向针和/或切割器提供加压空气。 手机中的电机可以驱动真空泵,压力泵和/或切割器。 真空传感器可以感测活检装置内的真空度,并响应感测的真空度引起操作循环的启动。 阀机构和离合机构的一部分可以一体地形成。 离合器和阀门机构可由第一电池供电的马达驱动; 以及由第二电池供电电动机的切割器,压力泵和真空泵。 因此,活检装置可以从手持件内提供真空,加压空气和动力,使得活检装置是无连接的。
