  • Patent number: 6945984
    Abstract: A microsurgical instrument is described for ophthalmologic microsurgery in the eye which comprises a housing configured as a handle with a functional unit supporting a probe and a rod co-axially supported in the probe having a head piece configured as a grasping element with two arms that can be brought into a spread apart first position and a second closed position, wherein each arm has a recess which upon closing are flush pressed together thereby forming a larger recess for unobstructed grasping, retaining and holding microstructures such as blood vessels without squeezing or pinching the microstructures.

  • Patent number: 6908476
    Abstract: A cutting instrument configured as scissors has a housing formed as a handle with a functional unit disposed therein; supported in the functional unit is a probe configured as a hollow needle which co-axially supports a rod projecting from the probe in axial direction and which comprises at its distal end a cutting device and wherein the cutting device has two cutting members provided with cutting blades that can be configured in an arc-shape or a straight shape, wherein from an open position the cutting blades correspond to each other at an acute angle, they are brought into engagement with each other to a closed position for a cutting action by means of a sliding movement of the probe relative to the scissors tip.

  • Patent number: 6685725
    Abstract: A surgical instrument, in particular ophthalmologic clamp, includes two substantially parallel spring arms interconnected at their rear end and having a forward end terminating in clamping elements. An actuating mechanism is provided for moving the spring arms relative to one another in opposition to a spring elastic restoring force of the spring arms to thereby implement an inverse movement of the clamping elements. The actuating mechanism includes two plate-shaped operating members and four pins, whereby the pins are so disposed that two pins are connected to one operating member and the distal one of the spring arms, and two pins are connected to the other operating member and the other of the spring arms.
