1. A surgical fastener applier for ensuring proper seating of a fastener comprising:
- a housing;
an actuation mechanism disposed in mechanical cooperation with the housing and defining a longitudinal axis;
a rotatable center drive mechanism operatively associated with the actuation mechanism;
a rotatable drive rod extending distally from the housing and configured to support a plurality of fasteners, the rotatable drive rod being at least partially radially surrounded by the plurality of fasteners;
an axially translatable tubular sleeve coaxially disposed along at least a portion of the drive rod and configured to at least partially radially surround said plurality of fasteners; and
a control system including a load measuring device supported in the housing, wherein the load measuring device is a load sensor, the control system being configured to prevent a motor of the drive mechanism from operation until a predetermined amount of an external load is directly applied to a distal portion of the tubular sleeve.

Abstract
The present disclosure is directed to a fastener applying surgical fastener applier for ensuring proper seating of a fastener within tissue. The surgical fastener applier includes an actuation mechanism, a drive mechanism, and a control system. The control system is configured to determine loading along an axis and to allow movement of the drive mechanism.

-
a housing; an actuation mechanism disposed in mechanical cooperation with the housing and defining a longitudinal axis; a drive mechanism operatively associated with the actuation mechanism; a rotatable center drive rod extending distally from the housing and configured to support a plurality of fasteners, the rotatable drive rod being at least partially radially surrounded by the plurality of fasteners; an axially translatable tubular sleeve coaxially disposed along at least a portion of the drive rod and configured to at least partially radially surround said plurality of fasteners; and a control system including at least one load measuring device supported in the housing, wherein the load measuring device is a load sensor, the control system being configured to activate a motor to allow movement of the drive mechanism once a predetermined load is equally distributed about the distal end of the tubular sleeve. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
