Gripping instrument

1. A gripping instrument comprising:

two jaw parts connected to each other by a pivot joint;

two grip arms connected to the two jaw parts, the two grip arms being movable towards each other by pushing together the two grip arms, and the two grips arms being movable away from each other by pushing apart of the grip arms; and

a bending joint disposed in at least one grip arm of the two grip arms, wherein:

the bending joint comprises:

at least one slit made in one side of the at least one grip arm in which the bending joint is disposed and by a cross-sectional tapering of the at least one grip arm in which the bending joint is disposed; and

a directional abutment formed by opposite end faces of the at least one slit;

when the two grip arms are pushed together, a force limited by a resiliency of the bending joint is transmitted via the at least one grip arm in which the bending joint is disposed to a corresponding jaw part of the two jaw parts; and

when the two grip arms are pushed apart, the opposite end faces of the at least one slit contact each other such that an applied manual force acts directly through the directional abutment.

2. The gripping instrument as claimed in claim 1 , wherein the bending joint is formed in the at least one grip arm and integral with the at least one grip arm.

3. The gripping instrument as claimed in claim 1 , wherein the at least one grip arm is slit on a side that faces away from the other grip arm.

4. The gripping instrument as claimed in claim 1 , wherein the at least one slit is formed substantially transversely or obliquely with respect to the longitudinal direction of the grip arm.

5. The gripping instrument as claimed in claim 1 , wherein the at least one slit is a plurality of slits, the plurality of slits being arranged along a longitudinal direction of the at least one grip arm, and the spacing between the plurality of slits defining a comb web.

6. The gripping instrument as claimed in claim 5 , wherein the comb web has a support element protruding from it, the directional abutment including the support element, and the support element bracing the comb web against a respectively adjacent comb web when the grip arms are moved away from each other.

7. The gripping instrument as claimed in claim 5 , wherein at least one of (i) the plurality of slits and (ii) the comb webs are spaced apart from each other at different distances.

8. The gripping instrument as claimed in claim 1 , further comprising a spring element that is arranged along a base web of the bending joint.

9. The gripping instrument as claimed in claim 8 , further comprising a spring element that is embedded in the at least one grip arm.

10. The gripping instrument as claimed in claim 1 , wherein the at least one slit is filled with a soft elastic filler component.

11. The gripping instrument as claimed in claim 10 , wherein the at least one slit is enclosed by a sleeve separate from the at least one grip arm.

12. The gripping instrument as claimed in claim 1 , wherein the gripping instrument is a surgical gripping instrument.

13. The gripping instrument as claimed in claim 1 , wherein the gripping instrument has a rotation abutment, which limits a movement of the jaw parts toward each other.

14. The gripping instrument as claimed in claim 1 , wherein a jaw part of the two jaw parts and a corresponding grip arm connected to the jaw part are formed integrally.

15. The gripping instrument as claimed in claim 1 , wherein the at least one slit is enclosed by a sleeve separate from the at least one grip arm.

16. The gripping instrument as claimed in claim 1 , further comprising a spring element that is embedded in the at least one grip arm.
