Abstract

There is provided a powered tacker device for use in installing multiple surgical fasteners through a prosthetic mesh into tissue. The powered tacker device generally includes a handle assembly and a tacker assembly extending distally from the handle assembly. The handle assembly includes a motor and self-contained power assembly to rotate the surgical fasteners into tissue. The handle assembly is provided with a drive assembly which allows for rotation, as well as distal longitudinal movement, of a surgical fastener relative to the powered tacker device. The tacker assembly includes an inner tube for containing the plurality of surgical fasteners and a driver which is movable out of alignment with the inner tube so as to install a single fastener at a time into tissue.
