Abstract

See full text

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.
