ABSTRACT:
Surgical scissors devices are disclosed. The surgical scissors devices may comprise an end effector with first and second blade members. The first and second blade members may respectively comprise proximally positioned cams and distally positioned blade ends. Also, the first and second blade members may be coupled at a pivot point by a fastener held in tension along its longitudinal axis by the blade members. A reciprocating shuttle may comprise at least one pin positioned within slots defined by the respective cams of the blade members. Distally-directed motion of the shuttle may cause the first and second blade members to open and proximally-directed motion of the shuttle may cause the first and second blade members to close. Methods and apparatuses for forming the surgical scissors device are also disclosed.
