    摘要: A directional control valve arrangement includes a directional control valve with a valve spool. Using the directional control valve, it is possible to control a pressure-medium connection between a pressure port, a tank connection, and at least one working connection. A blocking valve is situated in a working passage that is connected to the working connection. The pressure in the working passage can be reduced using a pressure-release unit; the pressure-medium connection between the working passage and the tank connection is blocked by the valve spool. The pressure-relief unit has an intermediate space which is formed in the pressure-medium flow path between the blocking valve and a control edge of the valve spool that blocks the working passage to the tank port, the intermediate space being provided to accommodate a compression volume of the working passage. The intermediate space can be connected to the working passage by controlling-open the blocking valve, and the connection to the tank port is blocked by the control edge of the valve spool.

    摘要: A multifunctional instrument for use in microinvasive surgery includes an operator hand grip, a multi-lumen tube fastened on the operator hand grip, at least two guide channels coaxially configured inside the tube, and surgical instruments that are displaceably and rotationally disposed in the guide channels. The instrument also includes a shaft at whose distal end one surgical working element each is disposed. The instruments can be displaced between a rest position, in which the respective working element is retracted into the tube, and a working position, in which the respective working element projects from the distal end of the tube. The instruments can be displaced into and out of the working position by means of a motor and at least one of the instruments can be rotated in its working position by means of a motor. The instrument can be controlled by means of an electronic control that controls at least the motor-driven displacement motions and rotational motions of the surgical instruments and the tube.

    摘要: A method for controlling image capturing and spatial control in a device monitored by imaging, in particular an endoscopic instrument, for examination and manipulation purposes, wherein the work region and the position and action of the device are monitored by means of one of the display means displaying the observed work region via optics. The device is held and moved by motor-driven equipment depending on the display, the respective position and intended action. The eye movements of the operating person or the line of sight during observation of the display is registered according to the eye-tracking method and used to control the image capturing and tracking and the display.
