  • Patent number: 12539132
    Abstract: A tissue-resecting end effector assembly includes an outer shaft having a hub housing disposed about a proximal end portion thereof, an inner shaft rotatably disposed within the outer shaft and having a distal driver disposed about a proximal end portion thereof, a proximal driver, a retainer cap, and an RFID chip. The proximal driver is slidably coupled to the distal driver in fixed rotational orientation. The retainer cap is fixedly engaged with the hub housing, thereby fixing the retainer cap relative to the hub housing and the outer shaft. The retainer cap is configured to selectively lock the proximal driver in fixed rotational orientation, thereby selectively locking the inner shaft relative to the outer shaft. The RFID chip is disposed within a pocket of the retainer cap that is closed upon engagement of the retainer cap with the hub housing, thereby retaining the RFID chip therein.

  • Patent number: 12076049
    Abstract: An end effector assembly of a tissue-resecting device includes an outer shaft, a drive wire, the distal cutting tip, a hub housing, and a driver. The outer shaft includes a distal end portion defining a window therethrough. The drive wire extends through the outer shaft. The distal cutting tip is disposed within the outer shaft and engaged with the distal end portion of the drive wire. The distal cutting tip at least partially overlaps the window. The hub housing is engaged with the proximal end portion of the outer shaft. The driver is disposed within the hub housing and engaged with the proximal end portion of the drive wire to driver rotation of the drive wire and distal cutting tip within and relative to the outer shaft. The driver defines an internal lumen and at least one lateral opening disposed in communication with the internal lumen.

    Abstract: A continuous flow endoscope device includes an elongated tubular member defining an interior, a first channel disposed within the interior of the elongated tubular member, a second channel disposed within the interior of the elongated tubular member, and an optics device disposed in a free space of the interior of the elongated tubular member. The second channel is configured to receive an instrument therein during a first portion of an operation. A lumen defined through the second channel is fluidly isolated from a lumen defined through the first channel. The free space of the interior of the elongated tubular member being a space within the interior of the elongated tubular member not occupied by either the first channel or the second channel.

  • Patent number: 11980382
    Abstract: A tissue-resecting end effector includes an outer shaft having a hub housing, an inner shaft including a sun gear, and a drive assembly disposed within the hub housing. The drive assembly includes a first and second drivers disposed about the inner shaft distally and proximally of the sun gear, respectively. The drive assembly further includes a plurality of planetary gears radially disposed about and in meshed engagement with the sun gear between the drivers, and a locking clip proximal of the planetary gears and the sun gear, rotationally keyed to the second driver, and engaged with the first driver via at least one snap-fit engagement. The locking clip retains the drivers and the planetary gears in operable engagement with one another and the sun gear such that a rotational input provided to the second driver drives rotation of the inner shaft.
