The invention relates to a device for manufacturing an elongated hollow profile element that has at least one pulling wire (13), comprising: two counter-bearings (11, 12), which are arranged on opposite sides of the device and which correspond to the elongated ends of the elongated hollow profile element, wherein one end of the at least one pulling wire (13) is anchored to the distal counter-bearing (11), and a mold (2a, 2b), which forms a sealed elongated cavity (3) that can be filled with a hardening material, wherein the cavity (3) extends between the two counter-bearings (11, 12) and the pulling wire (13) extends in the cavity (3) so as not to touch the cavity wall. The invention further relates to a method for manufacturing an elongated hollow profile element that has at least one pulling wire (13), the elongated hollow profile element, and a bending section for an endoscope.

A vehicle may include a flutter resistant caster. The vehicle may include a frame, a drive wheel coupled to the frame, a caster housing coupled to the frame, a caster, a locking element, a first bearing, and a biasing element. The caster housing may include an opening. The caster may include a caster wheel and a caster stem extending through the opening in the caster housing. The caster stem may be configured to rotate relative to the caster housing. The locking element may be coupled to the caster stem. The first bearing may be coupled to the caster stem. The biasing element may be coupled to the caster stem. The biasing element may be configured to exert a force on the first bearing.

The present invention relates to a non-magnetic needle bearing for use in a rotational machine such as, for example, an MRI. The needle bearing may include needles, a cylindrical retainer holding the needles at a predetermined pitch, an outer ring outside of the retainer, and an inner ring inside the retainer. All of the aforementioned may be made of a non-thermoplastic polyimide resin.

A drive unit for providing drive from a robot arm to an instrument, the drive unit comprising: a plurality of drive elements for engaging corresponding elements of the instrument, each drive element being movable along a drive axis and the drive axes of each of the drive elements being substantially parallel to each other; and a load cell structure comprising a plurality of deflectable bodies coupled to the drive elements for sensing load on the drive elements parallel to their drive axes, and a frame comprising an integral member supporting the deflectable bodies in such a way as to isolate each deflectable body from load applied to the or each other deflectable body.

A jaw closure transmission system is presented comprising an input sub-system, output sub-system and a transmission sub-system.

A flexible connecting system consists of a flexible connecting rod manufactured from a rigid material, a leading segment and a trailing segment. The body has at least one flexible center section, each having at least one slot to provide flexibility. The slot follows a sinuous, serpentine path to form a plurality of interlocking teeth that can follow a helical or a concentric path. One or more flexible sleeves are dimensioned to fit over the connecting rod to prevent the ingress or egress of material. One or both of the ends of the flexible connecting rod and flexible sleeve can be open or sealed.

A securable rail guide contains a guide rail, a runner rail arranged in the guide rail and able to travel along the guide rail, and a securing unit which is embodied to fix the runner rail in position in the guide rail in a releasable manner. A locking unit is arranged on the guide rail and is embodied to secure the runner rail in a locked position, and an unlocking unit is arranged on the runner rail. The locking unit and the unlocking unit are parts of the securing unit. The unlocking unit is operatively connected to the locking unit such that an actuation of the unlocking unit releases the runner rail to allow a free movement along the guide rail. This configuration provides a separation of the locking and unlocking mechanisms, as a result of which an independent configuration of the stability of the overall locking mechanism is possible.

According to one embodiment, an X-ray diagnostic apparatus includes a first arm, a second arm, a holding structure, an X-ray tube and an X-ray detector. The first arm rotates by a first rotating shaft and slides along a first arc-like slide axis relatively to the first rotating shaft. The second arm rotates by a second rotating shaft and slides along a second arc-like slide axis relatively to the second rotating shaft. The holding structure is connected with a first arm side and configured to hold the second arm. The X-ray tube and the X-ray detector are installed on the second arm.

A self-acting, sealed hydrodynamic bearing includes a bearing shaft; a bearing bushing arranged to seal a length of the bearing shaft; a lubricant provided in the sealed length of the hydrodynamic bearing; and a bearing arrangement between the shaft and bushing. The bearing shaft and/or the bearing bushing are configured to be rotatable. The bearing arrangement includes a primary bearing surface disposed on the bearing bushing, arranged to face a secondary bearing surface disposed on the bearing shaft. The primary and/or secondary bearing surfaces includes first regions having a first fluid slip characteristic, and second regions having a second fluid slip characteristic substantially different to that of the first fluid slip characteristic. The second and first regions are in a same plane of a cross-section of the primary and/or secondary bearing surfaces, and are disposed in an interleaved pattern over the primary and/or secondary bearing surfaces.
