Abstract: A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

Abstract: An electrically driven vehicle contains a current collector for supplying electrical energy from a bipolar overhead line system. The collector has an articulated support rod, which bears, on the contact wire side, a contact collector having a contact strip, and which is coupled, on the vehicle side, to a lift drive for positioning the support rod and for pressing the contact collector to a contact wire of the overhead wire system, a detection device for detecting a lateral position of a contact point of the contact wire on the contact strip and a driver assistance system for executing an automatic steering intervention as a function of the detected lateral position of the contact point. The vehicle has increased availability for a feed of electrical energy from the overhead line system in that the contact strip is supported on the contact collector via at least two spring elements.

Abstract: The application relates to a medical instrument with a hollow shaft, at the proximal end a handle is arranged, and at the distal end a tool with two jaw parts is arranged, of which at least one jaw part is pivotable, wherein the distal end is configured as a tool tip that can be deflected, and the tool tip is rotatable, wherein the rotation of the tool tip is effected via a first actuation element which is operatively connected at the proximal end to the handle, and wherein the deflection of the tool tip is effected via a second actuation element which is operatively connected to the handle, and wherein the at least one pivotable jaw part is adjustable between a closed position and an open position via a pull/push element. The pull/push element is mounted eccentrically in the tool tip and parallel to the longitudinal axis.

Abstract: A medical instrument for guiding a tool into an operating space including a shaft having first and second shaft segments connected to each other in an articulated manner, and an adjustment element arranged on one of the first and second shaft segments so as to be longitudinally movable along an adjustment direction, and adjustable in order to pivot the first and second shaft segments relative to each other. Furthermore, a connection element is provided as being connected in an articulated manner to the adjustment element via a first hinge connection and connected in an articulated manner to the other of the first and second shaft segments via a second hinge connection, such that, by adjusting the adjustment element along the adjustment direction, the first and second shaft segments are pivotable relative to each other. Accordingly, a medical instrument is disclosed that is easy to handle and permits advantageous force support.

Abstract: A minimally invasive manipulating system and a manipulating apparatus for instruments are disclosed. The apparatus comprises a frame and at least one instrument carrier including a holding section for an instrument arm. The instrument carrier is movably mounted to the frame and arranged to be coupled with at least one drive. The instrument carrier is at least sectionally rotatable about its longitudinal axis. The holding section comprises a driving interface that involves at least one transmission port. An instrument drive is assigned to the transmission port. The instrument carrier comprises a transmission section in which at least one transmission element is arranged that is configured for motion transmission between the instrument drive and the transmission port. The at least one transmission element is arranged concentrically with respect to the longitudinal axis. The transmission port is arranged off-center with respect to the longitudinal axis.

Abstract: Endoscopic instrument having a shaft extending between a proximal end and a distal end along a longitudinal direction, wherein a working section on the distal end and an actuating element on the proximal end are operatively connected by a thrust element extending along the longitudinal direction, wherein the working section has a jaw piece with first and second jaw parts, which jaw piece is arranged pivotably on a jaw part holder, which is arranged in the shaft so as to be displaceable along the longitudinal direction and rotatable about the longitudinal direction and the thrust element is coupled to the jaw piece, wherein the jaw piece, in the closed state, can be retracted into the shaft, and a blocking device is provided in the instrument which is configured to block a retraction of the jaw piece into the shaft in a predefined angle range about the longitudinal direction.

Abstract: An endoscopic instrument, in particular an endoscope, with a jointed portion of a shaft for connecting a distal part of the shaft with a proximal part of the shaft in a way to be angulated. For this purpose, the distal shaft part is connected with the proximal shaft part by two rigid jointed bars of different lengths, wherein each of the rigid jointed bars attaches with a joint on the distal shaft part and a joint on the proximal shaft part.
