The medical clip is made partially by a generative manufacturing process, in which the medical clip has at least one first clip portion and at least one second clip portion. The at least one second clip portion is formed directly onto the at least one first clip portion by a generative manufacturing process.

The two clamping arms abut against one another in a basic position and are movable away from one another against the action of the biasing element into an open position. At least part of a surface of the clip is of colored configuration. The clip defines at least three clip regions that are spatially separate from one another. Adjacent clip regions of the at least three clip regions are of differently colored configuration.

Abstract: A surgical retractor system includes a substantially tubular retractor having several segments which can be irreversibly severed from one another to carry out a length adaptation of the retractor. A segment is subdivided into an expanding section and a plate section of differing radial flexibility and connected to each other in a one-piece material bond to allow plastic radial expansion of the retractor. An extractor can be operated to bring about plastic radial constriction of the retractor contrary to the radial expansion of the retractor.
