Abstract: A functional element to be mounted on a retractor for performing cardiothoracic surgery has a securing device for mounting it releasably on the retractor. A device for holding up a beating heart lifted from an operating site has several spreadable strip-shaped holding fingers. It is proposed that three or four strip-shaped holding fingers are present which are designed to be bendable so that they can be shaped to form a holding basket adapted to the particular heart which is to be held.

Abstract: A retractor has a rail, a first holding arm protruding from this rail at an angle at a second holding arm extending approximately parallel to the first holding arm. A distance between the two arms being modifiable. At least one functional element is mounted on one of these holding arms, which functional element has a section extending transversely to the holding arms and a swivel bracket protruding from this transverse section. The functional element being pivotable about a pin extending roughly parallel to the arms via the swivel bracket, a swiveled position can be set by grasping the function element with a hand. A locking mechanism serves for locking the functional element in a swiveled position.

Abstract: A medical instrument for endoscopic removal of the saphenous vein has an elongated shaft which hat at the distal end a spatula tip and in whose proximal region is arranged a laterally projecting handle. The instrument further has an endoscopic optical system which has an eyepiece cup that is arranged at the proximal end of the instrument. The handle is joined to the shaft in such a way that an outer side of the instrument facing away from the handle continuously has a surface that, from the distal to the proximal end, is free of projections. The eyepiece cup is arranged in oblique orientation with respect to a longitudinal center axis of the shaft and encloses with the handle, with respect to the longitudinal center axis, an angle of less than 90°.
