Abstract
An end effector assembly of a tissue-resecting device includes an outer shaft defining a window, a drive wire extending through the outer shaft, and a distal cutting tip disposed within the outer shaft. The drive wire includes a cylindrical body and a distal end portion defining a semi-cylindrical configuration including a semi-cylindrical bottom surface and a planar top surface having a semi-cylindrical cut-out defined therein. The distal cutting tip at least partially overlaps the window and has a semi-cylindrical lumen defined by a semi-cylindrical bottom surface and an open top. The distal end portion of the drive wire is at least partially received and within the semi-cylindrical lumen with the semi-cylindrical surfaces substantially mating. The drive wire is configured to drive rotation or oscillation of the distal cutting tip relative to the outer shaft.
