ABSTRACT:
A swaging apparatus for attaching sutures to surgical needles includes at least a first die and a second die. The first die has a first member, which includes a first surface, and a second member, which includes a second surface. The second member is movable relative to the first member between an extended position, in which the second surface extends beyond the first surface, and a retracted position, in which the second surface does not extend beyond the first surface. The second die has at least one surface and is movable relative to the first die between a remote position and an adjacent position. When the second die moves relative to the first die from the remote position towards the adjacent position, the second member of the first die is caused to move from the extended position towards the retracted position, and the surfaces of the first and second dies cooperate with one another so as to swage a surgical needle positioned between the first and second dies. The second member of the first die is movable to the retracted position when the second die abuts the first die. In this manner, surgical needles of many different types or sizes can be swaged by the swaging apparatus.
