Abstract
Description
Die Erfindung betrifft ein medizinisches Instrument mit mindestens einem an eine Pumpe anschließbaren Saug- und/oder Spülkanal und mit mindestens einer manuell betätigbaren Stelleinrichtung zur Steuerung der Saug-/Spülleistung in dem mindestens einen Saug- und/oder Spülkanal.The The invention relates to a medical instrument having at least one connectable to a pump Suction and / or flushing channel and with at least one manually operable adjusting device for Control of the suction / rinsing performance in the at least one suction and / or irrigation channel.
Aus der Praxis sind verschiedene Ausführungsformen von medizinischen Instrumenten bekannt, die einen an eine Pumpe anschließbaren Saug- und/oder Spülkanal aufweisen. Zur Regulierung der Saug-/Spülleistung im Saug- und/oder Spülkanal weisen diese bekannten Instrumente eine manuell betätigbare Stelleinrichtung auf, über die mechanische Ventileinrichtungen zum Verschließen des Saug- und/oder Spülkanals betätigt werden. Aufgrund der permanent anliegenden Pumpleistung ist es in den wenigsten Fällen möglich, einen hundertprozentigen Verschluss des Saug-/Spülkanals zu erzielen. Darüber hinaus bedürfen die Ventileinrichtungen einer regelmäßigen Wartung und gründlichen Reinigung, insbesondere im Bereich der Dichtflächen.Out In practice, various embodiments of medical Instruments known to be connected to a suction pump and / or flushing channel exhibit. To regulate the suction / flushing power in the suction and / or irrigation channel These known instruments have a manually operable Setting device on, about the mechanical valve means for closing the suction and / or scavenging channel actuated become. Due to the permanently applied pumping power it is in the least cases possible, to achieve a 100% closure of the suction / irrigation channel. Furthermore need the valve devices of a regular maintenance and thorough cleaning, especially in the area of sealing surfaces.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein medizinisches Instrument zu schaffen, das bei einfachem Aufbau eine zuverlässige Steuerung der Saug-/Spülleitung gewährleistet.From that Based on the object of the invention, a medical Instrument to create, with a simple structure reliable control the suction / rinse line guaranteed.
Die Lösung dieser Aufgabenstellung ist erfindungsgemäß dadurch gekennzeichnet, dass über die manuell betätigbare Stelleinrichtung die Leistung der Pumpe steuerbar ist.The solution This task is inventively characterized in that on the manual actuated Control device, the power of the pump is controllable.
Durch die erfindungsgemäße direkte Kopplung der Pumpe mit der manuell betätigbaren Stelleinrichtung ist es erstmalig möglich, direkt die Pumpleistung der Pumpe zu steuern, so dass bei abgeschalteter Pumpe auch hundertprozentig keine Saug- oder Pumpleistung mehr am Saug- und/oder Spülkanal anliegt.By the direct invention Coupling of the pump with the manually operable actuator is it possible for the first time directly control the pump power of the pump, so when switched off Pump also 100% no suction or pumping power is applied to the suction and / or irrigation channel.
Gemäß einer praktischen Ausführungsform der Erfindung wird vorgeschlagen, dass die Übertragung der Betätigung der Stelleinrichtung an die Pumpe funkgesteuert erfolgt. Die beispielsweise auch im OP-Bereich freigegebene Bluetooth-Technik ist vorteilhaft, da sie drahtlos arbeitet und somit schnell und platzsparend einsetzbar ist.According to one Practical embodiment of Invention is proposed that the transmission of the actuation of Setting device to the pump is radio-controlled. The example Also in the operating room approved Bluetooth technology is beneficial as it is wireless works and thus can be used quickly and space-saving.
Um dem Operateur die Bedienung der erfindungsgemäß ausgebildeten manuellen Stelleinrichtung weiter zu erleichtern, wird erfindungsgemäß vorgeschlagen, die Steuerung der Saug- oder Pumpleistung der Pumpe und die manuelle Betätigung der Stelleinrichtung proportional miteinander gekoppelt sind, so dass die Saug- oder Pumpleistung beispielsweise linear zur Position der Stelleinrichtung oder auch mittels eines anderen Algorithmus steuerbar ist. Je nach Anwendungsfall ist es darüber hinaus möglich, die Proportionalität, das heißt, den gewünschten Algorithmus zur Steuerung der Leistung der Pumpe in Abhängigkeit von der Position der Stelleinrichtung individuell einzustellen.Around the operator the operation of the inventively designed manual adjusting device To further facilitate, the invention proposes the control the suction or pumping power of the pump and the manual operation of the actuator are coupled proportionally to each other, so that the suction or pumping power For example, linear to the position of the adjusting device or is controllable by another algorithm. Depending on the application is it about it out possible, the proportionality, this means, the desired algorithm to control the power of the pump depending on the position of the pump Adjust adjusting device individually.
Mit einer bevorzugten Ausführungsform der Erfindung wird vorgeschlagen, dass die manuelle betätigbare Stelleinrichtung als Hand-Kipphebel ausgebildet ist, der vorteilhafterweise im Bereich der Handhabe am medizinischen Instrument angeordnet ist, um direkt vom Operateur bedient werden zu können.With a preferred embodiment The invention proposes that the manual actuable Adjusting device is designed as a hand rocker arm, the advantageously is arranged in the region of the handle on the medical instrument to can be operated directly by the surgeon.
Schließlich wird mit der Erfindung vorgeschlagen, dass die manuelle Betätigung der Stelleinrichtung über eine elektronische Positionserfassung, beispielsweise einen Sensor oder ein Potentiometer, erfassbar ist.Finally will proposed with the invention that the manual actuation of Actuation device over an electronic position detection, such as a sensor or a potentiometer, is detectable.
Weitere Merkmale und Vorteile der Erfindung ergeben sich anhand der zugehörigen Zeichnung, in der ein Ausführungsbeispiel eines erfindungsgemäßen medizinischen Instruments nur beispielhaft dargestellt ist, ohne die Erfindung auf dieses Ausführungsbeispiel zu beschränken.Further Features and advantages of the invention will become apparent from the accompanying drawings, in the one embodiment a medical invention Instruments is shown only as an example, without the invention to this embodiment to restrict.
