A handpiece is disclosed for a multifunctional instrument for endoscopic surgery. The handpiece comprises a case; a connector disposed on the case and adapted to be connected to connecting lines such as electrical lines, liquid supply and discharge lines, and the like; at least one ultrasonic transducer arranged in the case; an ultrasonic sonotrode transmitting the ultrasonic energy; and at least one switch for controlling functions of the handpiece. The handpiece is characterized by, among other things, the provision that the sonotrode includes a long and thin probe section with a duct composed of several segments which are welded to each other.

An endoscope for inspection of an observation cavity, in particular of an observation cavity in which a hot medium and/or infrared radiation is present, has a shaft in which an optical system is arranged. The shaft has an inner shaft and an outer shaft surrounding the latter at a distance, the optical system being arranged in the inner shaft. The shaft is configured in the region of its distal end in such a way that it is substantially opaque to electromagnetic radiation in the infrared spectral range.

An endoscope is provided having a shaft and a handle extending to the side of the shaft at the proximal end. A mechanism is provided for pivoting the view direction in an observation area and has at least one operating element being engaged with the mechanism for actuating the mechanism. The at least one operating element is positioned on the handle, such that the mechanism is actuatable with at least one finger or thumb of the same hand holding the handle.

A lighting system for illumination of an observation space, especially an observation space in which a pressurized and/or hot medium is contained, comprises an optical-fiber cable, one end of which can be connected to a light source, and a lighting head, which is connected to the other end of the optical-fiber cable and whose distal end can be introduced into the observation space through an opening in a wall enclosing the observation space. The lighting head comprises a light guide rod made from a pressure and/or temperature-resistant material.

A medical gear pump is used for suction and irrigation, in particular for endoscopy or the laboratory, and it has two meshing gears as conveying elements, one of which is joined to a drive mechanism. The gears are received in non-journal-mounted fashion in openings, and are each equipped with a helical tooth set. It is proposed to configure the helical tooth set such that, when viewed along a surface line of said gears, at least two tooth tip/root contact points of said meshing gears are present, and a contour of tooth spaces of the one gear is matched to the teeth of the other gear in such a way that when a tooth has completely penetrated into the tooth space, its tooth tip almost completely fills up the tooth space radially inside the pitch circle.
摘要:
What is described here is a system for centrally monitoring and/or controlling at least one unit for endoscopy and particularly for minimally invasive surgery, such as an insufflation means, a pump, a light source and/or a video camera, wherein the unit or units to be controlled are interconnected via interfaces. The inventive system is characterised by the combination of the following features: the units are connected via the interfaces on a self-configuring bus to a BUS master, the BUS master configures the bus automatically, the BUS master monitors the communication on the bus for correct execution.

The present invention relates to a system for the central control of devices used during an operation, including a first control unit for control of the devices. The system is characterized in that a second control unit is provided which is connected to the first control unit for exchange of information. The first control unit may be embodied as closed system for control of at least those devices which carry out safety-related functions (safety-related devices), and the second control unit may be embodied as open system for control of the remaining devices which carry out non safety-related functions (non safety-related devices). The invention further relates to a method for the central control of devices.
摘要:
According to the invention, the use properties of a shock wave apparatus are improved by providing a metrological detection of the pressing force in addition to a sensual perception of the pressing force by a user. In this context, the invention relates to a shock wave apparatus having a housing and a contact device held at the housing, wherein the contact device is held via a force sensor at the housing in such a way that a force is transmitted from the contact device to the housing via the force sensor, at least partially.
