The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved. When a force is transmitted from the tool to the force transmission element in the longitudinal direction thereof, the leg spring cannot be rotated about the pin such that the force transmission element and the tool cannot be moved.

Medical instrument and method

A remote manipulator system according to the invention for carrying out manipulations in a body-internal cavity comprises a manipulator apparatus with a motor-driven actuator mechanism for moving at least two endoscope apparatuses that are insertable through a respective access opening into the body-internal cavity, said endoscope apparatuses each having an elongate shaft (), wherein the at least two endoscope apparatuses are each displaceable along a longitudinal direction and pivotable about a pivot point () defined by the respective access opening, an operating apparatus () with at least two control elements (), which each have an elongate shaft ('), wherein the at least two control elements () are each, in manual fashion, displaceable in the direction of a longitudinal axis and pivotable about a pivot point (), and a controller () which is embodied to detect a respective longitudinal displacement and pivot movement of the at least two control elements () and actuate the manipulator apparatus () in such a way that the movements of the endoscope apparatuses correspond to those of the at least two control elements (), wherein the operating apparatus () is embodied in such a way that a relative position of the pivot points () of the control elements () is adjustable.

A trocar sleeve comprises a flexible hollow shaft comprising a distal end and a proximal end, and a handling head that is formed at the proximal end of the hollow shaft. The trocar sleeve is manufactured from an elastomer material. The hollow shaft comprises an inner contour that is adapted to an outer contour of a trocar mandrel in such a way that the trocar sleeve and the trocar mandrel are arranged to be coupled to one another while generating a defined preload to stabilize the trocar sleeve. A trocar system comprises a trocar sleeve and a trocar mandrel that is arranged to be inserted in the trocar sleeve, while generating a defined preloading in the trocar sleeve. A method of manufacturing a trocar sleeve involves integrally forming a hollow shaft and a handling head in a common mold by molding.

A system for holding an image display apparatus () for displaying an image captured by means of an image capturing apparatus () comprises a movable holding apparatus () for an alterable hold of the image display apparatus (), a controllable drive device () for moving the holding apparatus (), comprising a control signal input () for receiving a control signal, and a controller () comprising a signal input () for receiving a signal that represents an orientation or a change in the orientation of the viewing direction () of the image capturing apparatus () in space or that facilitates a determination of the orientation or the change in the orientation of the viewing direction () of the image capturing apparatus (), and comprising a control signal output (), couplable to the control signal input () of the controllable drive device (), for providing a control signal for controlling the controllable drive device (). The controller () is embodied and provided to control the controllable drive device () in such a way that, within a predetermined range of possible orientations of the viewing direction () of the image capturing apparatus () in space, the orientation of the image display apparatus () in space is a predetermined function of the orientation of the viewing direction () of the image capturing apparatus () in space.

Medical instrument

A sealing device for sealing a lead-through for a medical instrument that includes a fastening region for fastening the sealing device on a tube or other medical device, a ring-like supporting region which is connected to the fastening region, and an annular sealing lip with an outer edge which is connected to an inner edge of the support portion, and an inner edge which is provided and designed to fluid-tightly abut at an outer surface of a shaft inserted in the sealing device. The difference of the average diameter of the inner edge of the support portion and the mean diameter of a shaft of a medical instrument, for which the sealing device is provided and designed, is not larger than the difference of the average diameter of the shaft and the mean diameter of the inner edge of the sealing lip.

Trocar

A trocar sleeve has a hollow shaft having a distal end and a proximal end, the shaft having a rectilinear shaft axis, an external thread rising from an outer surface of the shaft, wherein a first external thread having a shape of a helix has a height, measured from the outer surface up to a vertex of the helix, the height of the helix, seen along the rectilinear shaft axis from distal to proximal increases, and wherein a pitch of the helix, seen along the rectilinear shaft axis from distal to proximal decreases.

An endoscopic surgical instrument with an elongate shaft, a surgical tool arranged at a distal end of the shaft for conducting surgical manipulations and a handle arranged at a proximal end of the shaft for actuating the surgical tool. The shaft has an elongate shaft tube and an elongate actuation rod arranged movably within the shaft tube, the tool and the handle both being connected to the shaft tube and the actuating rod such that the tool can be actuated by the handle through a motion of the actuating rod relative to the shaft tube.

Surgical instrument

A sealing device for a medical instrument includes a fastening area and a sealing area designed to either bear on the circumference of a medical instrument inserted into the sealing device or to close the sealing device when no medical instrument is inserted. The sealing device further includes a first elastic wall enclosing the sealing area in a ring shape, with an annular first edge, which is connected to the sealing area, and an annular second edge, and a second elastic wall which encloses the first wall in a ring shape and is spaced apart there from, with an annular first edge and an annular second edge, which is connected to the fastening area.
