摘要:
An endoscopic instrument includes a first instrument part adapted for introduction into a cavity of a human body and having an introduction channel therein for passage of gas therethrough, and a second instrument part having a connection channel therein adapted to be connected to the first instrument part introduction channel. The second instrument part is adapted for connection to a gas source to provide gas, at a flow rate suitable for insufflation of a human body cavity, from the gas source through the connection channel to the introduction channel for introduction into the human body. A heating device heats the gas in the introduction channel to substantially the temperature of the human body.

A network bus for interconnecting a plurality of medical devices is described in which the devices are provided with modules adapted to communicate along the bus. Some of the devices are capable of assuming control over the bus with network master modules. A self-configuring capability is provided with which several network master capable medical devices automatically determine which network master is to take over control over the network bus and each individually is capable of controlling and operating the network. Each network master capable device has an extended network management module with which automatic master selection is achieved. This is done by monitoring or observing network communications for particular objects. Once such an object has been detected, a network master capable device is automatically selected to take over control on the basis of its priority. The selected network master module in turn monitors the network bus for objects indicative of another medical device which has a higher priority, while other connected master network capable medical devices continue to monitor the network bus to detect whether the current master is de-activated or fails to operate as master. The extended network module thus automatically enables another network master capable device to take over control over the network bus.

The invention concerns a high-frequency surgical instrument comprising two electrodes which are designed as forceps jaws and to which a high-frequency current from a high-frequency generator can be applied such that a high-frequency current flows between the jaws through the area of tissue to be treated. The instrument according to the invention is characterized in that, for alternative cutting and coagulation, an electrically non-conductive spacer is provided which is introduced between the electrodes when tissue is being cut. At least one duct is provided for flushing and/or removal purposes.
摘要:
A device for the irrigation and suction drainage of body cavities, especially in surgical laparoscopy, hysteroscopy, uroscopy, or arthroscopy. The device comprises two conventional pumps, each being equipped with a pressure sensor and being preferably designed as rotary tube pumps. The irrigation pump and the suction drainage pump are connected with each other by way of a control line, and they operate in a master-slave mode. Operation is very simple, in that only the irrigation pump needs to be adjusted and operated by the operator. Control of the suction drainage pump takes place automatically based on the measured values of both pressure sensors in the irrigation and suction drainage conduits and the set r.p.m.'s of the irrigation pump. The primary advantage of the device resides in that the suction drainage pump takes care automatically of uniform pressure and flow relationships at the site of the surgery independently of the adjustment of the irrigation pump.

The present invention provides a magnetic rotor bearing for suspending a rotor in a contact-free manner, in particular the rotor of an axial- or radial-centrifugal blood pump, comprising a permanent- and electromagnet arrangement which stabilizes the position of, and suspends the rotor in a stator, in particular a housing, and comprises a circuit arrangement connected to at least one position sensor or to the position sensor operating circuit thereof for the rotor. The rotor is suspended in the stator in a stable, contact-free manner by means of a permanent magnet arrangement except for a single geometric adjusting degree of freedom. The position of the rotor is stabilized only within the geometric adjusting degree of freedom not stabilized by the permanent magnet arrangement, by a permanent magnet arrangement located in the rotor and comprising at least one permanent magnet. The permanent magnet arrangement which co-operates with the electromagnet arrangement comprises at least one permanent magnet of the permanent magnet arrangement provided for suspending the rotor and consists in particular, of the permanent magnets of this permanent magnet arrangement positioned in the rotor. The circuit arrangement is a control circuit stabilizing the position of the rotor, during the absence of external forces, in a position of minimum energy requirement of the electromagnet arrangement.

In the case of a pressure container comprising a plastic container core (2) for storing a fluid under pressure, a support sheath (3) surrounding the plastic container core (2), a connection piece (4) formed at the plastic container core (2) and having an opening (5) for filling in and discharging the fluid from the plastic container core (2), a connection body (6) arranged radially outside the connection piece (4) and having a bore (7), a valve body (8) having a fluid duct (9) for conducting the fluid in and out through the opening (5) in the connection piece (4), wherein the valve body (8) is arranged in the opening (5) of the connection piece (4) and in the bore (7) of the connection body (6), preferably at least one annular groove (10) formed radially outside in the valve body (8), one first seal (11) being arranged in each of the at least one radially outside annular groove (10), so that the at least one first seal (11) rests radially inside on the connection piece (4), the valve body (8) is to be attached reliably in a fluid-tight manner to the connection piece (4) of the plastic container core (2) and the valve body (8) and the connection body (6) have a small constructional height.This object is achieved by the fact that the connection body (6) has at least one radially inside annular groove (12) and that a second seal (13) is arranged in each of the at least one radially inside annular groove (12), so that the at least one second seal (13) rests radially outside on the connection piece (4).
摘要:
The invention relates to a method for a regular preparation of an apparatus for a treatment of a human or animal body by mechanical shockwaves to such a treatment wherein an impact body 9 used for shockwave production is replaced with a not-used impact body 9 before each treatment of a further patient.
摘要:

The present invention relates to a system for the central control of devices used during an operation, comprising a first control unit for control of said 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.
