Abstract

The invention relates to a device for guiding surgical sewing material to a needle, having a shaft on whose distal end the needle can be secured and whose proximal end is configured as a gripping portion equipped with an open guide channel for the sewing material that is to be guided. To create a device that is of simple construction and ensures reliable transport of the sewing material to the needle, the invention proposes that the guide channel can be locked mechanically, at least in sections.

Claims

1. A device for guiding surgical sewing material to a needle, having a shaft on whose distal end a needle can be secured and whose proximal end is configured as a gripping portion equipped with an open guide channel for the sewing material that is to be guided, wherein the guide channel can be mechanically locked, at least in sections by means of at least one locking element configured in the guide channel, distinguished in that the at least one locking element has two blocking elements that are contiguous with one another and that, at least in sections, lock the guide channel above the sewing material, so that the sewing material can be pressed from above into the guide channel, and distinguished in that that every locking element is configured as a threaded bolt that can be screwed into the gripping portion from the side opposite the guide channel, and in the shaft of this threaded bolt a guiding groove is configured corresponding to the guide channel, such that the shaft can rotate freely on the threaded bolt.

2. A device according to claim 1, distinguished in that the at least one blocking element is configured as an O-ring consisting of a plastic or rubber material.

3. A device according to claim 1, distinguished in that the blocking elements are positioned on the free ends of the shaft of the threaded bolt divided in half by the groove.

4. A device according to claim 1, distinguished in that on the rotatable shaft at least one positioning element is configured, which interacts with a corresponding positioning element in the gripping portion.

5. A device according to claim 4, distinguished in that the positioning element configured on the rotatable shaft is configured as a longitudinal rib, which can be inserted into a corresponding longitudinal groove in the gripping portion.

6. A device according to claim 1, distinguished in that the guide channel can be covered at least in sections by means of at least one locking device.

7. A device according to claim 6, distinguished in that the locking device is configured as a covering lid positioned on the gripping portion.

8. A device according to claim 6, distinguished in that the locking device is configured as a clamp that can be secured on the gripping portion.

9. A device according to claim 8, distinguished in that the clamp is configured as a spring element surrounding the gripping portion.

10. A device according to claim 6, distinguished in that the locking device is configured as a sleeve that can be slid onto the gripping portion.

11. A device according to claim 1, distinguished in that a gripping hollow is configured on the distal end of the gripping portion in the shaft for clamped gripping of the sewing material.

12. A device according to claim 6, distinguished in that a guide groove is configured on the floor of the gripping hollow to receive the sewing material.
