  • Publication number: 20210378664
    Abstract: A surgical device is provided and includes a handle housing, an endoscopic assembly, and a follower assembly. The endoscopic assembly extends distally from the handle housing and includes an inner tube defining a longitudinal axis. The inner tube includes a distal portion defining a pair of opposed tines. The endoscopic assembly is configured to support a plurality of anchors at least partially therein. The follower assembly is disposed at least partially within the inner tube at a location proximal of the plurality of anchors, and includes a head and a shaft. A portion of the head is disposed between the pair of opposed tines. Actuation of the endoscopic surgical device causes rotation of the inner tube about the longitudinal axis relative to the handle housing, and causes distal advancement of the follower assembly relative to the inner tube.

  • Patent number: 10835341
    Abstract: A handle assembly for use with a surgical instrument includes a housing defining a contact wall, a movable handle, a plunger, a linkage, and a feedback mechanism. The plunger is disposed at least partially within the housing and defines a longitudinal axis. The linkage interconnects the movable handle with the plunger such that actuation of the movable handle results in longitudinal translation of the plunger relative to the housing. The feedback mechanism is configured to provide audible feedback to a user, and includes an indicator snap wire and a track defined by a wall of the housing. The snap wire is configured to move along the track in response to longitudinal translation of the plunger. The snap wire is configured to engage the contact wall of the housing to create a sound that is audible to a user when the movable handle has been actuated a predetermined amount.
