Surgical scissors
First Claim
1. A method of forming surgical scissors comprising first and second blade members joined between first and second arms of a clevis at a pivot point, wherein the first and second blade members and the first and second arms each define pin holes at the pivot point, the method comprising:
- positioning the first and second blade members of the surgical scissors and the clevis such that the pin holes of the first and second blades align with the pin holes of the first and second arms of the clevis;
applying a compressive force to the first and second blade members and the clevis, wherein the compressive force is directed to force the first and second blade members towards one another between the first and second arms of the clevis, wherein applying the compressive force comprises;
placing at least a portion of the first blade member and at least a portion of the second blade member between a first clamp member and a second clamp member, andcompressing first and second clamp members towards one another with the first and second blade members therebetween; and
while maintaining the compressive force, applying a fastener through the pin holes of the first and second blade members and the first and second arms of the clevis, wherein the fastener is configured to join the first blade member and the second blade member, and wherein applying the fastener comprises at least one action selected from the group consisting of;
applying the fastener through at least a portion of the first clamp member; and
applying the fastener around at least a portion of the first clamp member.

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.
