  • Patent number: 9402614
    Abstract: A spreader for the atrium of the heart is disclosed, particularly for the exposure of the mitral valve, having a thin-walled axially continuous hollow retractor body, the diameter of which expands from a distal edge to a proximal edge. The wall of the retractor body is made of an elastically deformable flat material, preferably of a shape memory metal. At the proximal edge of the retractor body, a receptacle is arranged, into which a fixing rod for positioning and fixing the retractor body can be inserted.

  • Patent number: 7182730
    Abstract: An anal retractor includes four retractor valves (48), which are offset 90° relative to each other and can be moved radially apart from each other. For this the four retractor valves (48) are guided by sleds (30) in radial guide slots (14) of a base plate (10). For movement of the sleds (30) guide bolts (36) extend through the radial guide slots (14) of the base plate (10) and spiral shaped actuating slots (24) of a rotor plate (20), which is rotatable relative to the base plate (10).

  • Publication number: 20050273063
    Abstract: A suction instrument for surgery, wherein the grip and the suction pipe of the suction instrument are produced as separate parts. The grip is comprised of a handpiece with an axially extending inner channel. The suction pipe is introduced into the distal end of the hand piece and can thus be adjusted and varied in its effective working length by inserting the suction pipe different axially distances into the hand piece. In its respective adjusted axial position and rotation the suction pipe is force-fittingly fixed or friction locked in the hand piece. Friction locking allows the axial position of the suction pipe in the hand piece to be freely varied, so that an effective length of the suction pipe and its rotation position in regard to the hand piece can be adapted optimally to the respective operation requirements, and can be readjusted as the operation progresses.
