## Abstract

An aneurysm surgical clip includes two rotatably interconnected clip parts and a leg spring. The leg spring has two spring legs of which are in each case supported on the two clip parts so as to mutually pretension the two clip parts. The leg spring is formed from a plastics material, in particular PEEK, that is reinforced with continuous carbon fibers. The continuous carbon fibers are aligned along the spring coilings of the leg spring. The two clip parts have in each case one axially projecting protrusion on which the respective spring leg of the leg spring is supported.

## Claims

### Claim 1

A surgical clip, comprising:
two clip parts which are rotatably interconnected about a rotation axis and a leg spring, the leg spring having a spring coiling and two spring legs,
each of the two spring legs respectively being supported on one of the two clip parts so as to mutually pretension the two clip parts;
wherein the leg spring is formed from a plastics material that is reinforced with continuous carbon fibers, wherein the continuous carbon fibers are aligned along the spring coilings of the leg spring;
wherein the two clip parts have in each case a passage opening in which the spring coiling is disposed; and
wherein the two clip parts have in each case one protrusion which axially projects in a direction of the rotation axis and on which the respective spring leg of the leg spring is supported, wherein the protrusion is integrally molded externally on the clip part.

### Claim 2 (depends on 1)

The surgical clip according to claim 1, wherein the plastics material of the leg spring is PEEK.

### Claim 3 (depends on 2)

The surgical clip according to claim 2, wherein the two clip parts are formed from a plastics material.

### Claim 4 (depends on 3)

The surgical clip according to claim 3, wherein the plastics material of the two clip parts is PEEK.

### Claim 5 (depends on 3)

The surgical clip according to claim 3, wherein the plastics material of the two clip parts is reinforced with short carbon fibers.

### Claim 6 (depends on 1)

The surgical clip according to claim 1, wherein the two spring legs of the leg spring are connected to the two clip parts in a materially integral manner of being welded to one another.

### Claim 7 (depends on 1)

The surgical clip according to claim 1, wherein the protrusion is configured so as to be hook-shaped and reaches radially across the respective spring leg.

### Claim 8 (depends on 1)

The surgical clip according to claim 1, wherein the respective spring leg is at least partially embedded in the protrusion in a form-fitting manner of being melted therein.

### Claim 9 (depends on 1)

The surgical clip according to claim 1, wherein the two clip parts have in each case one clamping arm, one operating arm, and a rotary bearing portion located there between, said rotary bearing portion having an opening, wherein the rotary bearing portions of the two clip parts are mounted so as to be rotatable within one another, and the openings of the two clip parts form an axial passage opening in which at least some of the spring coilings of the leg spring are disposed.

### Claim 10 (depends on 1)

The surgical clip according to claim 1, wherein the spring leg is supported on an end face or inner face of the protrusion facing in the force direction of the leg spring or in the rotation direction of the clip, respectively.
