Surgical retractor extension for extending gripping section of surgical retractor has first coupling element of connecting section provided with at least one at least partially spherically formed surface

摘要

The surgical retractor extension (10) for extending the gripping section (12) of a retractor, with a connecting section (14) with a first coupling element (56) engaging with a second coupling element on the retractor gripping section, has the first coupling element provided with at least one at least partially spherically formed surface (64). The first coupling element is in the form of a projection which is at least partially spherically formed, or in the form of a recess with a surface which is at least partially hollow-spherically formed. An independent claim is included for a surgical retractor set which includes a surgical retractor extension.
