Abstract
An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.
Claims18
A system for forming a looped suture, the system comprising:
- a suture supply assembly configured for supplying a thread;
- a gripper assembly for positioning a first section of the thread adjacent a second section of the thread to form a loop in the thread;
- a carriage assembly configured for advancing the thread through a loop forming process;
- a welding assembly configured for securing the loop in the thread;
- and
- a trimming assembly configured for forming a tapered cut in the second section of the thread, the trimming assembly being configured to move in a first horizontal direction and in a second vertical direction, wherein rates of movement of the trimming assembly in the first and second directions affects the configuration of the tapered cut in the thread.
A system for forming a looped suture, the system comprising:
- a suture supply assembly configured for supplying a thread;
- a gripper assembly for positioning a first section of the thread adjacent a second section of the thread to form a loop in the thread;
- a carriage assembly configured for advancing the thread through a loop forming process;
- a welding assembly configured for securing the loop in the thread;
- a trimming assembly configured for forming a tapered cut in the second section of the thread, the trimming assembly being configured to move in a first horizontal direction and in a second vertical direction;
- and
- a thread lengthening assembly configured for extending a length of the thread.
