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.

Dependent claims

A powered tacker device comprising:

a handle assembly having a power source and a drive assembly mounted within the handle assembly, the drive assembly including a keyed journal rotatably mounted within the handle assembly and rotatable in response to actuation of the power source, a drive bar longitudinally movable relative to the keyed journal and a rotator rotatable in response to rotation of the keyed journal;
an actuator associated with the handle assembly and operable to engage the power source with the drive assembly;
and
a tacker assembly extending distally from the handle assembly and containing a plurality of surgical fasteners, the tacker assembly including an inner tube terminating in a driver engageable with the fasteners, wherein the inner tube is connected to the rotator and rotatable in response to rotation of the keyed journal,
wherein the keyed journal includes a threaded bore and the drive bar includes a threaded outer surface engageable with the threaded bore such that rotation of the keyed journal moves the drive bar in a longitudinal direction within the handle assembly, and wherein the drive bar is connected to the rotator to move the rotator longitudinally within the handle assembly in response to rotation of the keyed journal,
and wherein the keyed journal includes distally extending keys and the rotator includes slots engageable with the keys such that the rotator is rotated in response to rotation of the keyed journal.
