Abstract: An electrosurgical instrument configured for connection to a supply apparatus for operation. The instrument has an end opening at the distal end and supports at least one electrode in the area of the end opening to which an alternating voltage potential can be applied. Directly adjoining the end opening, a liner of the electrosurgical instrument limits a flow chamber inside the liner. With distance to the end opening a flushing channel opens out into the flow chamber via an exit opening and a suction channel opens out into the flow chamber via an inlet opening. A flushing fluid can be introduced in the flow chamber via the flushing channel and can be extracted by suction via the suction channel.

Abstract: A method for assembling a piezo valve can include providing a cable having first and second contacts, forming a pocket between the first and second contacts, inserting at least a portion of a piezo element into the pocket, electrically coupling the first contact to a first layer of the piezo element, and electrically coupling the second contact to a second layer of the piezo element. Forming the pocket between the first and second contacts can include moving the second contact from a first position, in which the first and second contacts can be coplanar, to a second position, in which the first and second contacts can be disposed in different planes.

Abstract: A control unit for displaying a traffic situation on a screen of an ego vehicle is designed to display a first traffic participant symbol for a first traffic participant in a first sub-region of the screen and a second traffic participant symbol for a second traffic participant in a second sub-region of the screen. The control unit is additionally designed to determine that the first traffic participant symbol and the second traffic participant symbol are approaching each other in a specified manner on the basis of a change in the position of the second traffic participant relative to the first traffic participant. In response thereto, the control unit is further designed to at least partly hide the first and/or the second traffic participant symbol.

Abstract: Instruments having a hood that defines and surrounds a flow chamber. The flow chamber can serve for suction of emissions that are produced due to influence of an electrode supplied with high frequency voltage on biological tissue. For elimination of tissue deposition and other clogging from the flow chamber the electrode is surrounded by a movable hood that can be transitioned for cleaning purposes out of its operating position into a cleaning position.

Abstract: An instrument according to the invention for medical or surgical treatment of a human or animal patient comprises at least one tool suitable for influencing a patient, e.g. an electrode, which is or are located in the field of view of an optical element. The optical element is arranged inside a channel in which a fluid flow can be maintained or can be caused in distal direction. The light passage window of optical element is offset relative to the distal opening of channel in proximal direction. A closure device is arranged between light passage window and opening of channel, which blocks passage of substances, particularly passage of liquid droplets and particles, from the opening to the light passage window as long as it is in closed position. If the closure device is open, it unblocks the fluid path and the light path between the light passage window to the opening. Preferably the closure device is controlled pneumatically by means of the liquid or gaseous fluid flowing inside channel.

Abstract: An apparatus (10) serves for attachment of a light receiving device (24) for light analysis on an instrument (11) or an instrument component (12) during surgery by the surgery user of a surgical instrument (11) or their assistant. The apparatus (10) is preferably configured to releasably attach the light receiving device (24) on the instrument (11) or the instrument component (12). The apparatus (10) can comprise a light receiving device (24) and an electrode (15) fixed relative thereto. The electrode (15) can alternatively also be part of the instrument (11). The apparatus (10) can be releasably attachable to the instrument (11) or the instrument component (12) and can form an adapter for attachment of the light receiving device (24) on the instrument (11) or the instrument component (12) or can also be configured as part of the instrument (10).

Abstract: An internal combustion engine having a crankcase with a base and an oil tank, wherein a first connection between the crankcase and the oil tank is formed with a first valve, which is open in the direction from the crankcase to the oil tank and closed in the opposite direction, and a second connection between the crankcase and the oil tank is formed with a second valve, which is open in the direction from the oil tank to the crankcase and is closed in the opposite direction. The first valve is arranged on the base of the crankcase and the second valve is arranged above the first valve.

Abstract: An adjustable balloon that includes a handle having an inflation port, an access cannula, a rotary handle, an inner sleeve and sharp tip. The inner sleeve extends within the access cannula to support compliant, inflatable structure. The access cannula may be retracted into the handle by operation of the rotary handle to expose the inflatable structure, such that the inflatable structure may have an adjustable length. The access cannula may include length indicators to show a length of the inflatable structure as a result of the access cannula being withdrawn into the handle.

Abstract: A system is configured to create or enlarge a cavity in a tissue body and generally includes a cannula, a friction reduction covering, and a cavity creation member. The cavity creation member includes an end portion that is configured to transition between a first shape and a second shape that is different from the first shape. In operation, retracting the friction reduction covering relative to end portion causes the end portion to change shape from the first shape to the second shape such that the cavity creation member is configured to create or enlarge a cavity in the tissue body as the second end portion exits the friction reduction member.
