Abstract

A thread catcher for surgical sewing material consisting of a handle, a hollow shaft positioned on the distal side of the handle, and a catching device that is mounted so that it can be slid lengthwise within the hollow shaft by means of a drive element and whose distal end, which can slide out of the distal end of the hollow shaft, is configured as a catcher loop. To create a thread catcher for surgical sewing material that is simple to operate and ensures rapid and secure grasping of the surgical sewing material, it is proposed with the invention that the catcher loop should consist of at least three segments that are distally connected with one another.

Claims (7)

1. A thread catcher for surgical sewing material comprising a handle, a hollow shaft positioned on a distal side of the handle, and a catching device that is mounted so that it can be slid lengthwise within the hollow shaft by means of a drive element and whose distal end, which can slide out of a distal end of the hollow shaft, is configured as a catcher loop, which has at least three segments that are proximally connected to the distal end of the catching device and that are distally connected with one another, wherein the at least three segments are positioned with respect to one another to encompass more than one plane so that the catcher loop makes it possible to catch the thread without orienting the thread catcher to the thread by rotation and wherein the catcher loop is drawn completely into the hollow shaft in a grasping position for fixing a grasped thread between the at least three segments;

wherein a groove running from a proximal end of the handle in a lengthwise direction of the handle and which is open to a top is configured in the handle for inserting the catching device;

wherein the drive element slides the catching device in the lengthwise direction relative to the handle.

2. The thread catcher according to claim 1 , wherein the segments of the catcher loop are configured as arched in the position where they are pushed out of the distal end of the hollow shaft.

3. The thread catcher according to claim 1 , wherein the segments of the catcher loop consist of a spring-elastic material.

4. The thread catcher according to claim 1 , wherein the drive element is configured as a hand-actuated thrust roller.

5. The thread catcher according to claim 1 , wherein the hollow shaft is a hollow sewing needle.
