Abstract: A housing for accommodating electric and electronic components is EMC safe in the manner of a Faraday cage. At least one accommodating chamber, open toward the outside of the housing and otherwise substantially closed to all sides, is formed in at least one outer wall of the housing. At least one non EMC safe transmitter in the form of a non EMC safe transmitting or receiving device is adapted to provide wireless communication between housing side control electronics and an external control device. A functional component is adapted to be controlled by the housing side control electronics. The transmitter may be an antenna, the arrangement thereof inside the accommodating chamber ensuring that it is located outside the EMC protection or shielding. The functional component can be a peristaltic-type pump that is protected by the arrangement inside the accommodating chamber and does not protrude from the housing.

Abstract: A method for displaying an ultrasound image on a display device is provided. Image signals are generated with an ultrasound probe during examination of an item under examination with ultrasound and are transferred to a data processing device. The image signals are displayed by the data processing device as an ultrasound image on a display device. In order to make it easier for an operator to observe the ultrasound image, by means of an orientation detection device, a change in orientation of the display device in space is detected and an associated change in orientation signal is provided to the data processing device and the orientation of the ultrasound image on the display device is changed by the data processing device as a function of the change in orientation of the display device in space. An apparatus for carrying out the method is also provided.

Abstract: A surgical clip is provided having two clip arms and a resiliently flexible element via which the two clip arms are connected to each other. The two clip arms each have a first free end, these first free ends being held parallel to and in contact with each other with a predetermined closing force by the resiliently flexible element when the clip is in a rest position. The clip arms are held at a second end opposite the free end on the resiliently flexible element. The clip arms have between their first and second ends sections configured to cross each other. The clip arms further have stop elements configured to complement each other. The stop elements are adapted to be brought in mutual contact when the clip is transferred from the rest position to an application position in which the free ends are spaced apart from each other.

Abstract: In order to provide a surgical clip device with which the closure of vessels is successfully achieved even more safely, particularly in neurosurgery, it is proposed that the surgical clip device be provided with at least two electrically conductive clip parts that are electrically isolated from each other (by an element) and are arranged at a predetermined distance opposite each other.

Abstract: A sterile container for the sterilization of surgical instruments is provided. The sterile container has a bottom wall, a side wall and a lid which, in a closed position of the sterile container, has a lid rim which engages over a free rim arranged on a side of the side wall that faces away from the bottom wall. At least one projection element is arranged between the bottom wall and the free rim. The projection element projects from the side wall in the direction of an outside of the sterile container at least as far as the lid rim and is located at a shorter distance from the bottom wall than the lid rim. The side wall, in a wall area between the at least one projection element and the free rim, does not protrude in the direction of a center of the sterile container over the side wall.

Abstract: A surgical clip is provided, having two clip arms and a resiliently flexible element pivotally connecting the two clip arms together. The two clip arms each have a first free end, which are held in parallel to and in contact with each other with a predetermined closing force by the flexible element in a rest position. At a second end opposite the free end, the clip arms are held connected to a wall section of the flexible element that is arranged substantially transverse to the longitudinal direction of the clip arms, extends between the second ends of the clip arms and has a first wall portion facing towards the clip arms and a second wall portion facing away from the clip arms. The flexible element is made from a plastics material by injection moulding. The first wall portion is produced with a greater shrinkage than the second wall portion.

Abstract: The invention relates to a medical clip carrier device for retention and/or mounting of at least one medical clip, in particular a ligature clip, comprising at least one clip receptacle in which a clip is retainable in a mounted position, and a securing device with at least one securing member for undetachably securing a clip in the at least one clip receptacle. The clip receptacle comprises an insertion opening for insertion of a clip into the clip receptacle and removal of the clip therefrom. The at least one securing member is constructed in the form of a retaining projection which protrudes at least partially into the insertion opening.

Abstract: An instrument includes a motor unit with a slide or piston. The operating direction of the slide or piston may be adapted to the bending and stretching movement of the user's index finger. A resiliently elastic extension or tongue transfers the bending and stretching movement of the index finger to the slide or piston on the side of the motor unit. The tongue is fixedly coupled to the slide or piston and extends above the handpiece along a gripping portion. The resilient flexibility of the tongue is selected so that it can be easily bent by the index finger resting on the tongue toward the gripping portion of the handpiece, which then serves as a contact or stop element for an operating element at the tongue and thus ensures fixed clamping of the handpiece between the thumb, the middle finger and the index finger.

Abstract: A gas operated surgical instrument is provided. The instrument includes a pressurized gas connection for connection to a source of pressurized gas, a working piston adapted to be acted upon by a pressurized gas, an actuating element for actuating the instrument, and a regulating device coupled to the actuating element and to the working piston for regulating a feed force of the working piston. The regulating device is configured such that, for feed forces below a predetermined limit force, it defines a first work area in which the working piston is movable in the distal direction solely owing to a feed force applied with the actuating element, and that above the limit force the regulating device defines a second work area in which the working piston is movable in the distal direction by being acted upon by pressurized gas.

Abstract: The invention relates to a surgical instrument for removing a surgical clip applied to a hollow organ, said clip comprising two clamping arms having two free ends and two ends connected to each other and defining a connecting region, and said instrument having a proximal and a distal end, wherein a spreading device for grasping and spreading apart an applied clip from an applied position to a released position is arranged at the distal end.

Abstract: A surgical clip cartridge is provided, having a housing member, a plurality of C-shaped surgical clips stored in the housing member, and a plurality of compartments provided on the housing member, each compartment being adapted for receiving a respective one of the surgical clips.

Abstract: A non-invasive method for the determination of a reference plane of the human pelvis is described in which method position coordinates of three points A, B, C of the reference plane are determined non-invasively in a reference coordinate system and the reference plane is calculated from the position coordinates of the three points A, B, C, wherein position coordinates of a first point A of the reference plane are determined non-invasively by detecting a first characteristic point (A) on the pelvis, which first characteristic point (A) is located on the reference plane. Furthermore, a device for non-invasively determining a reference plane of the human pelvis is also described.
