Abstract
A retractor features at least two retractor arms whose proximal end portions are fixed or integrally formed on opposite ends of a crossbar for adjusting the distance between the retractor arms, and a drive unit whose case is mounted on the crossbar and whose gearing is in operative connection with a length adjustment mechanism to be operated by a separate actuation element which can be brought into engagement with a gearing input element movably inserted in the case. The gearing input element is accessible on at least one outer side of the casing. The gearing input element is designed such that it is substantially flush with the case's outer side or is recessed into the case interior. It has its exposed side provided with recesses, at least one of which has an undercut which enters a manually detachable latching engagement with a force transmission protrusion of the actuation element.
