Abstract
Description
Die Erfindung betrifft eine Abrasionssonde für erkrankte Leit ungsbahnen und Hohlräume im Körper des Patienten, um schonend krankhafte Ein-Auflagerungen zur Therapie beseitigen zu können.The invention relates to an abrasion probe for sick guide pathways and cavities in the patient's body in order to be gentle to be able to eliminate pathological deposits in the therapy.
Zahlreiche Abrasionen sind seit Jahrzehnten besonders an der Gebärmutter vorgenommen worden mit Küretten, die vorn eine bügelförmige Schneide besitzen, die zur Vermeidung von Ver letzungen in diesem Bereich abgeschirmt ist. In neuer Zeit sind auch Fräsen vorn an langgestreckten ärztlichen Instrumenten wie Katheter/Sonden eingesetzt worden. Eine solche Vorrichtung in einem Katheter mit einem Düsenkopf und flexibler Welle ist in DE 33 26 648 beschrieben worden. Es seien auch mit Laser Plaques aus den Coronarien sozusagen durch Verbrennung be seitigt worden (Ärztliche Praxis, Jahrgang Nr. 69, 29.08.89). Schwierigkeiten können sich dabei durch Mikroembolien ergeben, insbesondere wenn solche ausräumende Prozeße in Erweiterung von Gefäßlumina bzw. zur Abrasion in Vorschaltung zum Gehirn vorgenommen werden. Auch pulverisiertes Abrasionsmaterial sollte möglichst aus der erkrankten Leitungsbahn wie bei der atheromatösen Arteriosklerose herausgebracht werden. Die Verwendung von Laser zeigt bereits die Tendenz, möglichst schonend von außen die Kräfte, welche der Verbesserung der Leitungsbahn dienen, einzusetzen.Numerous abrasions have been particularly on the for decades Uterus has been made with curettes, the front one have bow-shaped cutting edge, which to avoid ver is shielded in this area. Are in modern times also milling in front on elongated medical instruments such as Catheters / probes have been used. Such a device in a catheter with a nozzle head and flexible shaft have been described in DE 33 26 648. It is also with laser Coronary plaques, so to speak, by combustion (medical practice, year 69, August 29, 1989). Difficulties can arise from microembolism, especially when such clearing processes are being expanded of vascular lumens or for abrasion upstream of the brain be made. Also powdered abrasion material should, if possible, come from the diseased conduit as with the atheromatous arteriosclerosis. The Use of laser already shows the tendency, if possible gently from the outside the forces which improve the Serve to use.
Der Erfindung liegt die Aufgabe zugrunde, eine Sonde für Abrasion so zu gestalten, daß mit ihr auch in empfindlichen Leitungsbahnen bzw. Körperregionen/Organe krankhafte Ver änderungen in diesen Leitungsbahnen schonend beseitigt werden.The invention has for its object a probe for To design abrasion in such a way that even in sensitive Conduction pathways or body regions / organs pathological ver Changes in these conduits can be carefully eliminated.
Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Die weitere Ausgestaltung der Erfindung ist den Unteransprüchen, der Zeichnung und deren Beschreibung zu entnehmen.This task is carried out in a generic device the characterizing features of claim 1 solved. The further embodiment of the invention is the dependent claims, the drawing and its description can be seen.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit einer Sonde in der erkrankten Leitungsbahn des Körpers extracorporale Wellenenergie für Dilatation und zugleich Abrasionen fokussiert und damit die auf die Innenschichten der erkrankten Leitungsbahnen einwirkenden Kräfte bei zugleich schonendem Einsatz derselben verstärkt werden. Außen am Körper, gegebenenfalls auch an der inneren Körperoberfläche mit Schleim haut, hat sich der Generator für möglichst fokussierte Schwingungs- und Wellenenergie mit der Ankopplungsvorrichtung zu befinden. Die Sonde zur Abrasion wie Dilatation enthält zur weiteren Fokussierung der Wellenenergie wie insbesondere zur Verstärkung Mikrospheres bzw. verteilt zahlreiche Gasbläschen in einer elastischen gummiartigen Grundsubstanz, die durch die extra corporale Wellenenergie zu Schwingungen und Expansion des elastischen Grundkörpers in Verstärkung auch einer Abrasion angeregt wird. Die Abrasionssonde hat über die Dilatationssonde DE 39 30 600.3 hinaus in ihrem Außenmantel verstreut zahlreiche Erhabenheiten aufzuweisen, die stecknadelkopfförmig in die elastische Grundsubstanz eingespießt sein können, auch nicht im Körper des Patienten verloren gehen dürfen. Auch manuell können durch Drehungen oder Längsbewegungen der Sonde zusätzlich Abrasionen an der Stelle der Erkrankung einer Leitungsbahn be wirkt werden.The advantages achieved with the invention are in particular in that with a probe in the diseased conduit of the Body's extracorporeal wave energy for dilation and at the same time Abrasions focused and thus on the inner layers of the diseased conduction forces acting at the same time careful use of the same are reinforced. Outside of the body, if necessary also on the inner surface of the body with mucus skin, the generator has chosen the most focused vibration and to find wave energy with the coupling device. The probe for abrasion such as dilation contains for further Focusing the wave energy, especially for amplification Microspheres or distributes numerous gas bubbles in one elastic rubber-like basic substance, thanks to the extra corporal wave energy to vibrate and expand the elastic base body to reinforce abrasion is excited. The abrasion probe has over the dilation probe DE 39 30 600.3 also scattered numerous in its outer jacket To have grandeur, the pin-shaped in the elastic base substance can be impaled, also not may be lost in the patient's body. Also manually can be caused by rotations or longitudinal movements of the probe Abrasions at the site of the disease of a conduit be effective.
Es ist vor allem der vordere Teil der Abrasionssonde, welcher den in Patentanspruch 1 genannten Aufbau zur Abrasion besitzen muß. In queren Riffelungen des Mantels der Abrasionssonde wird sich der größte Teil des Abrasionsmaterials ansammeln und kann dann mit der Sonde vom Untersucher aus dem Körper des Patienten herausgezogen werden.It is above all the front part of the abrasion probe, which is the must have structure for abrasion mentioned in claim 1. In transverse corrugations of the jacket of the abrasion probe most of the abrasion material can collect and then with the examiner's probe from the patient's body be pulled out.
Varianten solcher Abrasionssonden können in Verbindung mit Kathetern und/oder Kanülen hergestellt werden, so daß auch Injektionen vorn an der Abrasionssonde in der Leitungsbahn möglich sind wie auch Aspiration.Variants of such abrasion probes can be used in conjunction with Catheters and / or cannulas are produced, so that injections at the front of the abrasion probe in the Conduction path are possible as well as aspiration.
