Drive mechanism for articulating tacker

摘要

A tacker for applying a rotary tack, including a drive shaft coupled to a trigger assembly, wherein operating the trigger assembly causes rotation of the drive shaft, a distal portion of the drive shaft passing into an articulated arm that holds rotary tacks, wherein upon operation of the trigger assembly, the drive shaft rotates to cause deployment of the tacks distally out of the articulated arm, and wherein the drive shaft includes a cable on which are located a plurality of axially spaced drive links that transfer rotational motion of the drive shaft to rotation of the tacks.

1. A tacker for applying a rotary tack, comprising:
a drive shaft coupled to a trigger assembly, wherein operating said trigger assembly causes rotation of said drive shaft, a distal portion of said drive shaft passing into an articulated arm that holds rotary tacks, wherein upon operation of said trigger assembly, said drive shaft rotates to cause deployment of said tacks distally out of said articulated arm; and wherein said drive shaft passes through apertures formed in a plurality of axially spaced drive links, each of the apertures being formed axially through each of the drive links, said drive links operable to transfer rotational motion of said drive shaft to rotation of said tacks.
