摘要： An endoscopic instrument including first, second and third portions, a first main hinge with a first main-hinge part, a further first main-hinge part and a first sub-hinge, a second main hinge with a second main-hinge part, a further second main-hinge part and a second sub-hinge, and a rigid main pressure rod. The first and second portions are connected via the first main hinge, such that the first and second portions can be angled. The first and third portions are connected via the second main hinge such that the first and third portions can be angled. The main pressure rod is coupled to the first and second sub-hinges, so that displacement of the first main hinge by angling the second portion relative to the first portion transmits a force, via the main pressure rod, to the second main hinge and causes an angling of the third portion relative to the first portion.

摘要： A medical instrument with a hollow shaft, at the proximal end of which a handle is arranged, and at the distal end of which a tool is arranged with a stationary jaw part and with a jaw part that is pivotable relative to the stationary jaw part, a distal end region of the shaft that carries the tool being designed as a tool tip that can be positioned at an angle with respect to the longitudinal axis of the shaft, and the tool being rotatable about the longitudinal axis of the shaft respectively about the longitudinal axis of the tool tip. The axially displaceable actuation element for actuating the pivotable jaw part of the tool are coupled to each other in such a way that, on the one hand, when the axially displaceable actuation element for positioning the tool tip at an angle is actuated, the axially displaceable actuation element for actuating the pivotable jaw part of the tool is necessarily movable at the same time in the axial direction, and, on the other hand, the axially displaceable actuation element for actuating the pivotable jaw part of the tool can be actuated independently of the axially displaceable actuation element for positioning the tool tip at an angle.

摘要： A handling device for a medical instrument includes a main body with a coupling for releasable mechanical connection to a proximal end of an outer shaft, a first actuation device movable relative to the main body, a second actuation device movable relative to the main body, a first coupling device coupling the first actuation device to a first transfer device for transferring at least a force or a torque, and a second coupling device coupling the second actuation device to a second transfer device for transferring at least a force or a torque. The coupling devices each have a decoupling position, in which the associated actuation device is decoupled from the associated transfer device. The decoupling positions of both coupling devices can only be reached when the outer shaft is not connected to the coupling on the main body in the manner provided for use of the medical instrument.

摘要： The invention relates to a medical instrument having a hollow shaft, whose proximal end can be connected to an operating unit and having a tool tip arranged at the distal end of the shaft having a tool arranged at the distal end of the tool tip, wherein the tool has two jaw parts, which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal side via the operating unit and wherein the tool tip can be pivoted via a joint mechanism relative to the longitudinal axis of the shaft.
In order to provide a medical instrument, which ensures a uniform transmission of tensile and compressive forces even via the pivot region to the tool tip, it is proposed according to the invention that the pivotable jaw parts are each coupled via an articulated drive element to the distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element spans the region of the joint mechanism between the distal end of the shaft and the proximal end of the tool tip.

摘要： This application provides an endoscopic device having at least one shaft with at least one portion deflectable, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes at least one first connection member and at least one second connection member. When the connection members are arranged in a straight position relative to each other, a straight-position spacing exists defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member and, when the connection members are arranged in a deflection position relative to each other, a deflection-position spacing exists which is defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member, and the deflection-position spacing in the deflection position is greater than the straight-position spacing in the straight position.

摘要： A handling device for a micro-invasive surgical instrument includes a gripping device, a shaft coupling, and a rod coupling. The gripping device is configured to guide and hold the handling device. The shaft coupling is configured to detachably couple a proximal end of a shaft to the handling device. The rod coupling is configured to slide in the handling device between an assembly position and a range of working positions to detachably couple a proximal end of a transmission rod to the handling device. The transmission rod is disposed in the shaft. The shaft coupling is configured to block the proximal end of the shaft in a predetermined position in which the proximal end of the shaft holds the rod coupling in the range of working positions.

摘要： A retractor for endoscopic surgery, having a first shaft portion, in which an actuation device is movable, and a second shaft portion coupled pivotably thereon. A transmission arm is articulated on a distal end of the actuation device. A retraction structure is connected to a distal end of the second shaft portion, which retraction structure can be releasably coupled, with its other end, to the second shaft portion via a coupling device. The coupling device has a slide, which is guided in the second shaft portion. The transmission arm is articulated on the second shaft portion by way of a peg-and-slot connection and is operatively coupled to the slide in order to move the latter longitudinally, wherein the coupling device can be transferred to a release state by longitudinal movement of the slide. An operating method for the retractor is also disclosed.
