Abstract

A station for cutting a barb suture is provided. The barb cutting station includes a suture transport assembly for supporting a first suture, a first knife assembly for forming barbs on the first suture, and a first clamp and position assembly for approximating the at least first suture towards the at least first knife assembly. The barb cutting station may further include at least a first suture cutting mechanism configured for severing the at least first suture when a defect is detected. The station may also include at least a first visual inspection assembly configured for detecting defective barbs.

Claims (20)

1. A barb cutting station comprising:

a suture transport including:

a base member;

an upper support member fixedly secured to the base member and including at least one rotary assembly; and

a lower support member adjustably secured to the base member and including at least one rotary assembly, the upper and lower support members operating to support at least one suture; and

at least one knife assembly disposed relative to the suture transport;

at least one clamp and position assembly disposed relative to the suture transport and the at least one knife assembly, the at least one knife assembly and the at least one clamp and position assembly configured to move relative to each other to form of barbs on the at least one suture; and

at least one visual inspection assembly disposed relative to the suture transport, the at least one visual inspection assembly configured for monitoring the formation of barbs on the at least one suture.

2. The barb cutting station of claim 1 , wherein the at least one visual inspection assembly is configured for detecting defective barbs.

3. The barb cutting station of claim 2 , wherein the defective barbs are misformed.

4. The barb cutting station of claim 1 , including at least one cutting mechanism configured for severing the at least one suture in response to detection of a defective barb by the at least one visual inspection assembly.

5. The barb cutting station of claim 4 ; wherein the at least one visual inspection assembly is configured to signal the at least one cutting mechanism to sever the at least one suture.

6. The barb cutting station of claim 1 , wherein the at least one knife assembly includes a blade and the at least one clamp and positioning assembly includes an anvil.

7. The barb cutting station of claim 1 , wherein the at least one visual inspection assembly is configured to terminate a barb forming process.

8. The barb cutting station of claim 1 , wherein the at least one rotary assembly of the upper support member includes a pin assembly for selectively engaging a looped end of the at least one suture.

9. The barb cutting station of claim 8 , wherein the at least one rotary assembly of the lower support member includes a clamp for selectively engaging an end of the at least one suture.

10. The barb cutting station of claim 1 , wherein at least one of the at least one rotary assembly of the upper support member or the at least one rotary assembly of the lower support member includes a tensioning device.

11. The barb cutting station of claim 1 , wherein the lower support member includes an adjustment mechanism for adjusting a distance between the lower support member and the upper support member.

12. The barb cutting station of claim 1 , further including a linear track for passage of the suture transport.

13. The barb cutting station of claim 1 , further including a base panel.
