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.

A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. The tissue collection cartridge may include at least one histological agent disposed therein, may include a fill indicator configured to indicate a fill level of tissue within the tissue collection cartridge, and/or may include a latch configured to seal the port closed.

A modular glaucoma implant for the treatment of glaucoma is described. Embodiments disclosed describe a glaucoma treatment device including an elongated fixation stent that allows aqueous humor to flow from the anterior chamber of the eye to the Schlemm's Canal when implanted. One or more drainage tubes can be inserted into the fixation stent such that the drainage tubes allow aqueous humor to flow from the anterior chamber of the eye to the suprachoroidal space. Surgeons can opt to add as many drainage tubes as desired based on the needed aqueous humor outflow rate.

A surgical forceps includes an end effector assembly including a first jaw member and a second jaw member pivotally engaged with one another. At least one of the first or second jaw member is pivotable between a spaced-apart position and an approximated position. The first jaw member includes first and second surfaces on opposite sides thereof. The first surface is disposed in opposition to the second jaw member. The second surface includes a cutting edge disposed on a proximal portion thereof. The second jaw member includes a proximal flange having first and second raised sidewalls defining a proximal channel therebetween. The proximal channel receives the cutting edge of the first jaw member when the first and second jaw members are in the approximated position. The cutting edge of the first jaw member is exposed when the first and second jaw members are in the spaced apart position.

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.

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. An outflow path is defined from the window through the outer shaft and about the drive wire, into an interior of the hub housing, through the at least one lateral opening, and through the internal lumen.
