Abstract: A brushless direct-current motor is provided includes an inner stator and an outer rotor. The rotor includes a rotor core disposed around the stator, an inner annular member mounted on a rotor shaft, and a plurality of radial blades extending angularly from the rotor core to the inner annular member forming a fan. A first end cap is provided including a radial back plate proximate the fan and a center opening in the radial back plate through which the rotor shaft extends. A second end cap is provided including a main body disposed adjacent the stator opposite the fan. The radial back plate of the first end cap includes at least one sloped surface forming at least one air gap such that the airflow generated by the fan is centrifugally guided within the first end cap by the sloped surface and caused to exit through the air gap.

Abstract: The invention relates to a device for retaining and moving a laparoscope during an operation, which comprises a securing unit for securing on a retaining arm, a receiving unit for retaining the laparoscope, as well as a main body. Furthermore, the device has a lever via which the receiving unit is secured to the main body. The main body is mounted on the securing unit in a rotatable manner about a first rotation axis via a first rotation unit. The lever is mounted on the main body in a rotatable manner about a second rotation axis via a second rotation unit. Furthermore, a first drive unit is provided, which, upon activation, drives the first and the second rotation unit in such a manner that the main body is rotated about the first rotation axis, and the lever is rotated about the second rotation axis by the same rotation angle in the opposite rotation direction.

Abstract: A surgical device is disclosed. The surgical device has an endoscope having a camera that generates image data, a viewing device that displays a moving image based on image data generated by the camera, and a manipulator that is coupled with the endoscope, the endoscope being movable by the manipulator. The surgical device also has a controller that controls the manipulator based on a control command, the moving image displayed on the viewing device changing based on a movement of the endoscope. The surgical device further has a sensor coupled with the controller, and an operating element coupled with the controller, the operating element having a first operating state and a second operating state. The sensor detects a moving object, which is used in a surgical procedure, and generates a movement signal based on a movement of the moving object.

Abstract: A surgical operation imaging device is disclosed. The surgical operation imaging device has an endoscope having a camera that generates image data, a manipulator that moves the endoscope, and a viewing device that presents a moving image based on the image data. The surgical operation imaging device also has a controller that controls the manipulator and the endoscope based on a plurality of operating states and an operating element coupled with the controller. The operating element has a first switching state and a second switching state. A selected operating state is selected from the plurality of operating states based on the operating element switching between the first switching state and the second switching state. The selected operating state is changed based on the operating element switching between the first switching state and the second switching state.

Abstract: An operating device (10) for controlling a medical apparatus (100), comprising a device body (11) and at least one switching element (12) arranged at the device body (11) and operable by a user by pressing, wherein the medical apparatus (100) is controllable via a switching state of the switching element (12), characterized by a radio transmitter (20) included in the device body (11) and coupled to the switching element (12) for outputting a radio switching signal indicating the switching state, a radio receiver (102) provided separately from the device body (11) and coupleable to the medical apparatus (100) for receiving the radio switching signal output by the radio transmitter (20), and an energy supply unit (16) for supplying at least the device body (11) with energy, wherein the device body (11) comprises a means for being attached to a hand and/or an arm of the user.

Abstract: A sewing machine includes a presser foot (2) mounted pivotably about a horizontally aligned axis (1), which is configured to cooperate with an undertransporting apparatus disposed on a support area (3) for a material to be sewn, which includes two material sliders (4, 5) mounted movably with respect to one another for the continuous transport of the material in a feed direction. Both material sliders (4, 5) are configured to be extended horizontally when viewed in the feed direction both in a region before and in a region after the axis (1) of the presser foot (2).

Abstract: The present invention is directed to an implant for total hip joint replacement and a method for manufacturing such implant. In particular, the present invention relates to improved acetabular liners, total hip prosthetic assemblies comprising such liners and methods for manufacturing such liners.
