Abstract

The drive has a drive motor, where the drive is completely integrated in a closed housing. The electrical energy required for the drive motor is inductively transferred via the housing by a transformer. The movement that is produced by the drive motor is transferred to a cutting device by a magnetic coupling that is effective by a closed housing wall. The housing takes function of an ergonomic handle for a keyhole surgery instrument.

Description

Mit einem Gerät zur Gewebeentfernung werden innerhalb der minimal invasiven Chirurgie neben kleinen auch größere Gewebeanteile oder ganze Organe durch die vorhandenen Inzisionen aus dem Abdomen entfernt. Dabei wird das Gewebe, welches aus dem Operationsbereich heraustransportiert werden soll, mit einer angetriebenen Schneideinrichtung zerkleinert. Die benötigte Drehbewegung dieser Schneideinrichtung wird entweder elektrisch über einen Antriebsmotor oder manuell mittels Kurbel erzeugt.With a device Tissue removal will be within minimally invasive surgery in addition to small and larger tissue shares or whole organs through the existing incisions from the abdomen away. In doing so, the tissue that comes out of the operating area is to be transported out, comminuted with a driven cutter. The needed Rotational movement of this cutter is either electrically via a Drive motor or manually generated by crank.

Vor jeder Anwendung wird das Instrument der minimal invasiven Chirurgie einschließlich des Gerätes zur Gewebeentfernung und dessen kompletter Antrieb autoklaviert. Das Autoklavieren erfolgt in einem luft- und dampfdicht verschließbaren Druckbehälter. Es gibt zwei Haupttypen des Autoklavierverfahrens. Beim Vakuumverfahren wird die Luft durch mehrmaliges Evakuieren (Leerpumpen) im Wechsel mit Dampfeinströmungen entfernt, beim Strömungs- beziehungsweise Gravitationsverfahren wird die Luft durch Sattdampf verdrängt (Dampfkochtopf-Prinzip).In front Every application becomes the tool of minimally invasive surgery including of the device autoclaved for tissue removal and its complete drive. The autoclaving takes place in an air and vapor tight sealable pressure vessel. It There are two main types of autoclaving process. In the vacuum process is the air by repeated evacuation (emptying) in alternation with Dampfeinströmungen removed, when flow or Gravitation process, the air is displaced by saturated steam (pressure cooker principle).

Problemproblem

Das Autoklavieren des Instruments der minimal invasiven Chirurgie einschließlich des Gerätes zur Gewebeentfernung und dessen kompletten Antriebs ist unumgänglich. Dabei werden jedoch einige Elemente des elektrischen Antriebs des Gerätes zur Gewebeentfernung erheblich chemisch, mechanisch und thermisch angegriffen, wodurch dessen Funktionsfähigkeit nicht dauerhaft gewährleistet ist.The Autoclaving the instrument of minimally invasive surgery including the Device for Tissue removal and its complete drive is essential. However, some elements of the electric drive of the equipment for tissue removal considerably chemically, mechanically and thermally attacked, whereby its functionality is not permanently guaranteed is.

Erfindunginvention

Durch eine hundertprozentige Abkapselung des kompletten Antriebs einschließlich seiner Energiezufuhr und Drehbewegungsübertragung wird dieser gegen alle negativen Einflüsse des Umfeldes geschützt, wodurch er uneingeschränkt autoklavierbar ist.By a one hundred percent encapsulation of the complete drive including its Energy supply and rotary motion transmission This is protected against all negative influences of the environment, which he fully autoclavable.

Weiterbildung der ErfindungDevelopment of the invention

Die Erfindung nach Anspruch 1 wird in ihrer Konstruktion durch die Ansprüche 2 bis 5 beschrieben. Dabei beschreibt Anspruch 5 die ergonomische Verwendung des Antriebsgehäuses des Gerätes zur Gewebeentfernung als Handgriff.The The invention according to claim 1 is in its construction by the claims 2 to 5 described. Claim 5 describes the ergonomic use of the drive housing of the device for tissue removal as a handle.

Darstellung der ErfindungPresentation of the invention

Der komplette elektrische Antrieb des Gerätes zur Gewebeentfernung wird in einem zu hundert Prozent geschlossenen Gehäuse eingebaut, welches gleichzeitig die Funktion eines ergonomischen Handgriffes übernehmen kann. Die für den Antriebsmotor benötigte elektrische Energie wird durch das zu hundert Prozent geschlossene Gehäuse induktiv mittels speziellem Trafo (Primärwicklung abnehmbar außerhalb des Gehäuses, Sekundärwicklung fest innerhalb des Gehäuses) übertragen. Um die Handhabung des Instruments der minimal invasiven Chirurgie zu erleichtern, kann die übertragene elektrische Energie innerhalb des Gehäuses in einem Energiespeicher zwischengespeichert werden, so daß eine ständige elektrische Verbindung während des Betriebes zu einer äußeren Energiequelle entfallen kann. Das heißt, dass das Gerät in den Pausen zwischen den Anwendungen geladen werden kann. Die vom Antriebsmotor erzeugte Drehbewegung wird mittels einer durch die geschlossene Gehäusewand wirkende Magnetkupplung zur Schneideinrichtung des Gerätes zur Gewebeentfernung übertragen.Of the complete electric drive of the device for tissue removal is installed in a one hundred percent closed housing, which at the same time can take over the function of an ergonomic handle. The for the drive motor needed Electric energy is closed by one hundred percent casing Inductive by means of special transformer (primary winding removable outside of the housing, secondary winding firmly inside the housing). To handle the instrument of minimally invasive surgery To facilitate, the transmitted electrical energy within the housing in an energy store be cached so that a permanent electrical connection while of operation to an external source of energy can be omitted. This means, that the device can be loaded during the breaks between applications. The The rotary motor generated by the drive motor is by means of a the closed housing wall acting magnetic coupling to the cutting device of the device for Transferred tissue removal.
