Abstract
Description
Operat i onsi nstrument, Katheter oder dergleichenSurgical instrument, catheter or the like
Die Erfindung betrifft ein medizinisches Gerät, z. B. urologisches Operationsinstrument, Katheter, Dreinagen oder dgl., dessen Schaft oder Korpus zumindest teilweise in die Harnröhre, die Harnblase oder den Körper eingeführt wird und mit einem die Gleitfähigkeit erhöhenden Mittel beschichtet ist. The invention relates to a medical device, e.g. B. urological Surgical instrument, catheter, tripod or the like, at least its shaft or body partially inserted into the urethra, bladder or body and with is coated with an agent increasing the lubricity.
Eingriffe bei denen der Schaft eines Operationsinstrumentes oder eines Katheters in die Harnröhre eingeführt wird, müssen mit großer Sorgfalt erfolgen, um Schädigungen des Harnröhrengewebes zu vermeiden. Interventions involving the shaft of an operating instrument or a catheter is inserted into the urethra must be done with great care, to avoid damaging the urethral tissue.
wie auch insbesondere Schädigungen durch das Liegen von Verweilkathetern herabzusetzen. D ies betrifft auch Schädigungen, die sich z. B. aus dem Abbau des in die Harnröhre eingeführten Kathetermaterials, das zu entzündlichen Reizungen führt ebenso ergeben, wie als Folge der Reizung der Harnröhrenschleimhaut durch die an sich rauhe und durch den Abbau noch rauher werdende Oberfläche bzw. den Druck des Katheters bzw. Instrumentes selbst. Hierdurch wie durch den fehlenden Urinfluß kommt es rasch zu einer Infektion des sich entwickelnden Sekretes bzw. Harnes. Auch Reibeeffekte durch Eigenbewegungen des Katheters lösen entzündliche Reaktionen aus. Fd ge dieser Entzündungen können desweiteren Blutungen und Ödeme der Harnröhrenschleimhaut oder anderer Schleimhäute sein und zu Strikturen führen. Bei Operationsinstrumenten die aus Metall bestehen, treten im Verlauf operativer Eingriffe elektrische Ströme auf, die durch die Schäfte des Operationsinstrumentes laufen und ebenfalls eine Schädigung der Urethraschleimhaut bewirken. Um solche Schädigungen hintanzuhalten, verwendet man sowohl bei Instrumentenschäften als auch bei Kathetern pasten- bzw. salbenförmige- bzw. gelartige Gleitmittel, welche die Gleitfähigkeit erhöhen sollen. Dieser rein mechanische Effekt wird im allgemeinen für nur sehr kurze Zeit erreicht. Hinzu kommt, daß die Gleitmittel gerade an den Stellen an denen sie besonders notwendig sind, nämlich dort wo in der Harnröhre besondere Reibungs- oder Druckeffekte erzeugt werden durch die Bewegung des Instrumentes rasch abgetragen werden mit der Folge, daß dort die Schleimhaut bzw. die Gewebswand dann dem blanken Schaft bzw. Katheter anliegt. Dses trifft in besonderem Maße für Verweilkatheter zu.as well as, in particular, damage caused by indwelling catheters in place to belittle. This also applies to damage caused by e.g. B. from the dismantling of the catheter material inserted into the urethra causing inflammatory irritation performs as well as as a result of irritation of the urethral mucosa the surface, which is actually rough and which has become even rougher due to the degradation, or the pressure of the catheter or instrument itself. This is like the lack of urine flow the developing secretion or urine quickly becomes infected. Even Rubbing effects caused by the catheter's own movements trigger inflammatory reactions. This inflammation can also lead to bleeding and edema of the urethral mucosa or other mucous membranes and lead to strictures. With surgical instruments made of metal, electrical currents occur in the course of surgical interventions that run through the shafts of the surgical instrument and also one Cause damage to the urethral mucosa. To prevent such damage, is used for both instrument shafts and catheters paste or Ointment-like or gel-like lubricants, which are supposed to increase the lubricity. This purely mechanical effect is generally only achieved for a very short time. In addition, the lubricant is especially necessary in the places where it is particularly necessary are, namely where special friction or pressure effects are generated in the urethra are quickly removed by the movement of the instrument, with the result that there the mucous membrane or the tissue wall then the bare shaft or catheter is present. This is particularly true for indwelling catheters.
Der Erfindung liegt die Aufgabe zugrunde, ein Gerät des eingangs genannten Aufbaus so auszubilden, daß die Gefahr einer Schädigung der Schleimhaut bzw. der Harnröhre auch an Stellen von Harnröhrenverengungen vermieden und der Infektion geschädigter Stellen vorgebeugt wird. The invention is based on the object of a device of the introduction to train said structure so that there is a risk of damage to the mucous membrane or the urethra also in places of urethral constrictions avoided and the infection damaged areas is prevented.
D iese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das die Gleitfähigkeit erhöhende Mittel ein haftender, die Reibung vermindernder glatter Überzug ist, der den Abbau des Schaftwerkstoffs verhindert, eine schwach saure Komponente enthält undlim Falle eines Operationsinstrumentes - elektrisch nicht leitfähig ist. This object is achieved according to the invention in that the lubricity increasing agent is an adhesive, friction-reducing smooth coating that prevents degradation of the shaft material, contains a weakly acidic component and in the case of a surgical instrument - is not electrically conductive.
Der Überzug, der vorzugsweise aus einem polymereri Kunststoff besteht, isoliert bei Operationsinstrumenten die im Instrumentenschaft fließenden Kriechströme gegenüber der Schleimhaut bzw. der Harnröhre, so daß der durch die elektrische Leitfähigkeit der bisher bekannten Schäfte auftretende nachteilige Effekt vermieden wird. Aufgrund der Haftungdes Überzugs auf dem Instrumentenschaft wird sichergestellt, daß dieser Gleitüberzug auch an den Stellen zur Verfügung steht, an denen beim Einführen und Bewegen des Instrumentenschaftes eine erhöhte Reibung auftritt. Der Einbau einer schwach sauren Komponente in das Überzugsmaterial verhindert die Entzündungs- und Infektionsgefahr. The coating, which preferably consists of a polymeric plastic, isolates the leakage currents flowing in the instrument shaft in surgical instruments towards the mucous membrane or the urethra, so that the electrical conductivity the disadvantageous effect occurring so far is avoided. Because of the adhesion of the coating on the instrument shaft ensures that this Sliding coating is also available at the points where during insertion and Moving the instrument shaft increases friction. The installation of a weakly acidic component in the coating material prevents inflammation and Infection risk.
Gemäß einer bevorzugten Ausführung der Erfindung liegt der pH-Wert der schwach sauren Komponente zwischen 5 und 6,8. Damit kann nicht nur der Vermehrung gewisser Keime vorgebeugt werden, sondern es wird weiterhin der Entstehung von Phosphatsteinen entgegengewirkt. D iese Calcium-Phosphatsteine sind gerade bei Dauerkathetern außerordentlich unangenehm. According to a preferred embodiment of the invention, the pH is the weakly acidic component between 5 and 6.8. So that can not only increase Certain germs can be prevented, but the formation of phosphate stones will continue counteracted. These calcium phosphate stones are extraordinary, especially for indwelling catheters unpleasant.
Ferner können dem Überzug Medikamente zum Bekämpfen von Entzündungen und Infektionen zugesetzt werden. Medicines to fight inflammation can also be added to the coating and infections are added.
Mit Vorzug besteht der Überzug, wie bereits angedeutet, aus einem Kunststoff-Film, der entweder aus einer Tauch- oder spritzfähigen Lösung oder mittels eines Sprays nachträglich aufgebracht wird. Instrumentenschäfte und Katheter lassen sich auf diese Weise nicht nur anläßlich ihrer Herstellung mit dem erfindungsgemäßen Überzug versehen, sondern der Überzug kann auch nachträglich vor dem Eingriff mittels Sprays aufgebracht werden. As already indicated, the coating preferably consists of one Plastic film made either from an immersion or sprayable solution or by means of a spray is applied subsequently. Leave instrument shafts and catheters in this way not only on the occasion of their production with the inventive Cover provided, but the cover can also be used subsequently before the procedure Sprays are applied.
