Abstract

A device and method for cutting-to-length surgical suture material uses a thread spool having a continuous thread of the surgical suture material, a thread advancing gripper for drawing off a defined length of surgical suture material, and a cutting unit for cutting the surgical suture material. By way of a deflection installation, the surgical suture material is placeable so as to be angled to the primary transport direction in at least one open loop. The length of the open loop can be variably adjusted. The cutting unit is positioned between the thread spool and the deflection installation.

First claim

What is claimed is:

1. A method for cutting-to-length surgical suture material, comprising the following method steps:
drawing off, using a thread advancing gripper, the surgical suture material from a thread spool having a continuous thread;
moving the thread advancing gripper forward to a predetermined terminal position, the predetermined terminal position comprising a joining location for connecting the surgical suture material to a needle;
subsequently placing the surgical suture material by way of a deflection installation positioned between the thread spool and the predetermined terminal position in at least one open loop that runs so as to be angled to a the primary transport direction of the drawn-off surgical suture material;
fixing a leading end of the surgical suture material in the needle while repositioning the deflection installation, and
subsequently cutting off the surgical suture material drawn off from the thread spool using a cutting unit.

2. The method according to claim 1 , wherein the length of the at least one open loop is variably adjustable.
