Abstract
Description
Das Bohren am Knochen wird häufig in der Medizin und Zahnmedizin hauptsächlich zum Befestigen von Schrauben und Implantaten verwendet. Beim Knochenbohren werden nicht selten wichtige anatomische Strukturen durch scharfe rotierende Instrumente (Bohrer) verletzt. Bisher wird kein Sicherheitssystem zur Vermeidung solcher iatrogenen Verletzungen beim Knochenfräsen angeboten. The Boring on the bone becomes common in medicine and dentistry mainly for attaching screws and implants used. Bone drilling is not rare important anatomical structures through sharp rotating instruments (Drill) injured. So far, no safety system to avoid offered such iatrogenic injuries during bone milling.
Hier wird ein innovatives Bohrsystem beschrieben, das zum Schutz vor intraoperativen Verletzungen wichtiger anatomischen weichgewebigen Strukturen dienen soll. Das neue System besteht aus speziellen Bohrern, Winkelstücken, Motoren und die dazu passenden elektrischen Steuereinheiten. Es werden hier nicht alle Komponenten des Systems beschrieben, sondern nur jene Teile, die patentiert werden sollen. Es ist sehr wichtig zu erwähnen, dass das neue System auf der Tatsache basiert, dass die zu schonenden Strukturen meistens in Kanälen verlaufen, die Weichgewebe enthalten, und sich von dem Knochen in ihrer Konstanz und Härte unterscheiden. Dieser Härteunterschied zwischen Hart- und Weichgeweben wird vom hier beschriebenen neuen System zur Vermeidung der Weichgewebeverletzung genutzt. Das System ist den konventionellen Bohrsystemen sehr ähnlich. Der einzige und entscheidende Unterschied ist die Ausstattung der Druckmessung, die aus einer Druckmesssonde und/oder einem Drucksensor und einem Druck ausübenden Instrument (Feder) besteht. Die neuen Sondenbohrer sind übliche metallische Bohrer, die den Gewebswiderstand beim Knochenbohren mit zentrischen bzw. exzentrischen, durch Tunnel verlaufende Sonden messen. Eine Alternative könnte sondenlose, druckempfindliche Bohrer sein, wobei die Bohrer den Gewebswiderstand direkt zu einem sich im Winkelstück befindenden Drucksensor übertragen, der den Gewebswiderstand und dementsprechend die Gewebehärte misst. In einer Modifikation könnte die Sonde auch außerhalb des Bohrers verlaufen. Die Sonde registriert die Härte des Gewebes durch die Messung des Widerstands des Gewebes gegen die Sonde. Je härter das Gewebe ist, desto mehr wird die Sonde in den Bohrer zurückgedrückt. Beim Ansetzen des Bohrers am harten Knochengewebe wird die Sonde nach innen gedrückt. Solange am Knochen gebohrt wird, bleibt der Druck auf die Sonde bestehen, bis sich die Härte des Knochens reduziert. Sodann fängt der Druck auf die Sonde an abzunehmen. Bei Erreichen irgendeines Weichgewebes, reduziert sich der Druck auf die Sonde sehr stark. Diese Druckunterschiede, verursacht durch den Gewebswiderstand, werden von einem an der Innenseite der Sonde angeschlossenen Drucksensor gemessen und weitergeleitet. Der Drucksensor kann ebenfalls innerhalb des Bohrers oder des Winkelstücks integriert werden. Die Sonde kann vor jeder Verwendung kalibriert werden um die beiden Zustände (minimaler und maximaler Druckzustand) vor jeder Behandlung festzulegen. Der Sondenausgangsdruck kann durch eine Feder am Drucksensor erreicht werden. Diese Feder kann sich im/am Bohrer oder im Winkelstück befinden und übt beim Einsatz des Bohrers einen stabilen Druck aus. Der Ausgangsdruck soll so eingestellt sein, dass weder die Bohreffektivität noch die Schutzfunktion beeinträchtigt werden. Für bessere Sauberkeit und Sterilisierbarkeit soll die Sonde abnehmbar sein, so dass die Röhre des Bohrers mit speziellen Bürsten sauber gehalten werden kann. Die Sondenlänge sollte der Bohrerlänge entsprechen. In angesetzter, aktiver Position sollte die Sonde die Ebene der Bohreroberfläche leicht oder nicht überschreiten. In passiver, abgehobener Position sollte sie die Ebene der Bohreroberfläche 1-2 mm nicht überschreiten. Die Dicke der Sonde sollte der Härte des verwendeten Metals entsprechen, so dass sie während des Bohrens nicht abbricht. Das Ende der Sonde, welches das Gewebe berührt, kann spitz, stumpf oder auch stumpf an der Spitze sein, jedoch ein scharfes Bohrgewinde besitzen. Bei spitzen Sondenenden wird die Bohrgeschwindigkeit nicht beeinträchtigt, jedoch nimmt die Schutzfunktion ab. Bei stumpfen Sondenenden könnte die Bohrgeschwindigkeit beeinträchtigt werden, jedoch wäre die Schutzfunktion höher. Bei einer Kombination zwischen beiden Typen von Sondenenden, wird die Bohrgeschwindigkeit möglichst wenig beeinträchtigt mit gleichzeitig ausreichender Schutzfunktion. Die Auswahl sollte je nach Durchmesser der Sonde gestaltet sein. Der Querschnitt der Sonde könnte rund oder eckig gestaltet werden. Die Sonde sollte an der Drucksensorseite einen Haken besitzen, die ein Abfallen der Sonde beim Gebrauch verhindert. Im sondenlosen Design dient der gesamt rotierende Bohrer als Sonde. Der Bohrer leitet den Gewebewiderstand zum Drucksensor. Der Ausgangsdruck könnte z. B. aus einer am Drucksensor angeschlossenen Feder entstehen.Here An innovative drilling system is described which is for protection intraoperative injuries of important anatomical soft-tissue structures should serve. The new system consists of special drills, elbows, motors and the matching electrical control units. It will be here not all components of the system are described, only those Parts to be patented. It is very important to mention that the new system is based on the fact that the to be sparing Structures mostly in channels which contain soft tissue, and from the bone in their constancy and hardness differ. This difference in hardness between hard and Soft tissues are avoided by the new system described here used the soft tissue injury. The system is conventional Very similar to drilling systems. The only and decisive difference is the equipment of the Pressure measurement consisting of a pressure measuring probe and / or a pressure sensor and exercise a pressure Instrument (spring) exists. The new probe drills are standard metallic ones Drills that reduce tissue resistance during bone drilling with centric or eccentric tunneling probes. A Alternative could be probeless, pressure-sensitive drill, the drills the Tissue resistance directly to an angle piece Transmit pressure sensor, which measures the tissue resistance and, accordingly, the tissue hardness. In a modification could the probe also outside of the drill. The probe registers the hardness of the Tissue by measuring the resistance of the tissue against the Probe. The harder the tissue is, the more the probe is pushed back into the drill. At the Attaching the drill to the hard bone tissue, the probe is after pressed inside. As long as the bone is drilled, the pressure on the probe remains persist until the hardness of the bone reduced. Then it starts pressure on the probe to decrease. Upon reaching any Soft tissue, the pressure on the probe is greatly reduced. These pressure differences, caused by the tissue resistance, are from a pressure sensor connected to the inside of the probe measured and forwarded. The pressure sensor can also be inside the drill or the elbow to get integrated. The probe can be calibrated before each use be around the two states (minimum and maximum pressure) before each treatment. Of the Probe outlet pressure can be achieved by a spring on the pressure sensor become. This spring can be in / on the drill or in the elbow and practice when using the drill a stable pressure. The outlet pressure should be set so that neither the drilling efficiency nor the Protective function impaired become. For better cleanliness and sterilization, the probe should be removable be so the tube Clean the drill with special brushes can be held. The probe length should correspond to the drill length. In an engaged, active position, the probe should be the plane of the drill surface easy or not. In passive, lifted position it should be the plane of the drill surface 1-2 mm. The thickness of the probe should be the hardness correspond to the metal used, so that during the Bohrens does not break off. The end of the probe that touches the tissue can pointed, blunt or blunt at the top, but a sharp one Own drill thread. For pointed probe ends, the drilling speed not impaired, however, the protective function decreases. With blunt probe ends, the Drilling speed impaired be, but would be the protective function higher. For a combination between both types of probe ends, is the drilling speed as possible little affected with sufficient protection at the same time. The selection should be designed according to the diameter of the probe. The cross section of the Probe could be designed round or square. The probe should be on the pressure sensor side have a hook that prevents falling of the probe in use. In the probeless design, the entire rotating drill serves as a probe. The drill directs the tissue resistance to the pressure sensor. The output pressure could z. B. arise from a spring connected to the pressure sensor.
