Abstract

A medical gripping tool includes a synthetic body and a metallic layer on a surface of the synthetic body, whereby the synthetic body is configured to be elastically reshaped in its expected application. According to the invention, the gripping tool is configured so that the metallic layer is structurally reshaped in the expected application.

Claims

1. A medical gripping tool comprising:

a synthetic body; and

a metallic layer on a surface of the synthetic body,

wherein the synthetic body is configured in order to be reshaped in its expected application; and

characterized in that the gripping tool is configured in such a way that the metallic layer is structurally reshaped in the expected application.

2. The medical gripping tool of claim 1, wherein the synthetic body includes a first gripping member, a second gripping member and a solid-state joint between the first gripping member and the second gripping member.

3. The medical gripping tool of claim 2, wherein at least one of the first gripping member or the second gripping member has a beam structure.

4. The medical gripping tool of claim 2, wherein at least one of the first gripping member or the second gripping member is configured to be reshaped in accordance with the fin-ray effect upon gripping an object.

5. The medical gripping tool of claim 1, wherein the metallic layer has an average granular size of at most 100 nm.

6. The medical gripping tool of claim 1, wherein the metallic layer is present on a gripping surface of the gripping tool.

7. The medical gripping tool of claim 1, wherein none of the metallic layer is present on a gripping surface of the gripping tool, or the metallic layer on the gripping tool is thinner than at other areas of the surface of the synthetic body.

8. The medical gripping tool of claim 1, wherein none of the metallic layer is present on a solid-state joint of the gripping tool, or the metallic layer on the gripping tool is thinner than at other areas of the surface of the synthetic body.

9. The medical gripping tool of claim 1, further comprising

a contacting device for electrically contacting the metallic layer;

wherein the metallic layer includes a portion on a gripping surface, and wherein the portion on the gripping surface is connected with the contacting device in electrically conductive manner.

10. The medical gripping tool of claim 1, wherein the metallic layer includes a nickel layer, the nickel layer having an average granular size of at most 100 nm;

and

a copper layer, the copper layer located between the synthetic body and the nickel layer.

11. A method for handling a medical object, having the following steps:

positioning on the medical object a medical gripping tool having a synthetic body and a metallic layer on a surface of the synthetic body;

reshaping the medical gripping tool in order to grip the medical object, such that the synthetic body is reshaped; and

wherein, upon reshaping the medical gripping tool, the metallic layer is structurally reshaped.
