A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. The driver can be connected to the piston rod via a joint. In a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau and the piston is thereby moved to its rear end position. In a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and, on account of the tensioning, is accelerated toward the first plateau and, as a result, the piston is moved toward the an dispensing end.

Device for administering a fluid

A device for administering a fluid can include a cylinder, a piston displaceable in the cylinder and connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp rotatable via a motor, and a ramp track extending along a helical line. The tensioning device includes a roller which is in contact with the ramp track. To perform a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau so the piston is moved to its rear end position. To perform a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and is accelerated toward the first plateau, thereby the piston is moved toward an open dispensing end. A control unit determines whether the tensioning procedure and/or dispensing procedure has taken place correctly.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. In a dispensing procedure, a ramp track is rotated until a roller runs over a transfer region and is accelerated toward the first plateau and, as a result, the piston is moved toward an open dispensing end. The ramp track runs on the face side of a wall extending along a circular path. A cover engages over the ramp track, the driver and the roller and has at least one scraper extending counter to the first direction and extending within the wall as far as the inner side of the wall, and thus scrapes off lubricant located on the inner side from the inner side.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. A dose setting means can be provided which comprises a spacer and a movement unit. The movement unit can move the spacer from a neutral position into an active position between the driver and the cylinder such that the driver is stopped by the spacer and therefore the piston stroke during the movement of the piston to the open dispensing end is shorter in comparison to the case in which the spacer is in its neutral position.

A device for administering a fluid is provided, with The tensioning device (S) has a ramp () which is rotatable by means of a motor () and has a ramp track () extending along a helical line, wherein the ramp track () ascends from a first plateau along a region of inclination (S, S) to a second plateau and descends from the second plateau to the first plateau via a transition flank (). The tensioning device (S) furthermore has a roller () which is in contact with the ramp track () and is mounted rotatably in a driver (), which is connected to that end of the piston rod () which protrudes out of the cylinder (), and therefore, upon rotation of the ramp (), the ramp track () runs below the roller (), which thereby rotates, wherein the roller () has a support region () which rests on the region of inclination (S, S) of the ramp track (), and at least one laterally adjoining side region () which has a smaller outside diameter than the support region () and which does not rest on the region of inclination (S, S) of the ramp track (), wherein, during rotation of the ramp, both the support region () and the side region () come into contact with an edge () of the ramp track (), said edge connecting the second plateau to the transition flank ().

An endoscope includes a main unit, which includes a centring bush with an inner surface which defines an axis of rotation; a first eccentric bush, which is mounted rotatable about the axis of rotation in the centring bush and comprises a first centring inner surface which defines a first rotation axis, wherein the first rotation axis is offset parallel to the axis of rotation by a first offset; a second eccentric bush which is mounted rotatable about the first rotation axis in the first eccentric bush and comprises a second centring inner surface which defines a second rotation axis, wherein the second rotation axis is offset parallel to the first rotation axis by a second offset; and an eyepiece, which is connected to the second eccentric bush and has an optical axis which is parallel to the second rotation axis.

Endoscope and method for centring an eyepiece in a main unit of an endoscope

Eyepiece for an endoscope

A rotation mechanism (rotating device) that can be easily accessed by the surgeon's finger to rotate an endoscope or similar instrument. The rotation mechanism is a device/component with a 'starfish' configuration, which can be attached to the endoscope/arthroscope just distal to the eyepiece (or to an alternate attachment to a camera). The starfish component has a plurality of projections that extend radially from the endoscope axis, and beyond the diameter of the mechanism on the camera head that grasps the arthroscope eyecup. The projections can be easily accessed by the surgeon's finger to rotate the endoscope.

Provided is an endoscope with a handle and an endoscope shaft connected to the handle, which has a bendable section and a rigid section, adjoining it, with a support extending in the longitudinal direction of the endoscope shaft, wherein the bendable section has a flexible outer tube the end of which facing the rigid section rests on the support, wherein a fixing sleeve is connected to the end section and covers the end of the outer tube facing the rigid section such that said end is clamped for fixing between the fixing sleeve and the support.

Endoscope

An endoscope is provided, comprising a first tube whose distal end is sealed with a cover glass disposed in a mount and an electric heating system for heating the cover glass, with the heating system comprising two electric connections which can be connected with a power source, and an electrically conductive coating which is applied to the inside of the cover glass and comprises two mutually spaced contact sections, of which one each is electrically connected with one of the connections, and with the mount being electrically conductive and a first of the two contact sections being electrically connected via the mount with the associated connection.

The invention relates to a medical instrument for cutting biological and especially human tissue, having a hollow cutting tube that can rotate by means of an engine around its longitudinal axis, on whose distal end at least one blade is mounted, as well as with a handle in which the cutting tube is mounted for control purposes. In order to produce a medical instrument for cutting biological and especially human tissue in which the powering of the cutting tube is of simple construction and involves minor losses of capacity, it is proposed with the invention that the engine is configured as a hollow-shaft engine mounted on the cutting tube.
