  • Patent number: 6648815
    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°.

  • Patent number: 5571217
    Abstract: A protective assembly for the head which has a circular support structure adapted to be connected to the head of the person wearing the protective assembly. A protective visor is pivotally connected to the support structure to be swiveling from a lower operating position to an upper resting position. Mechanisms, having actuating members, are provided for adjusting and fixing the position of the visor in the viewing direction and in the lower operating position. All of the actuating members are located at the outer side of the protective assembly and the visor respectively, such that they can be activated while the protective assembly is being worn.
