Description

Koagulationselektrode für Endoskope Die Erfindung bezieht sich auf eine I(oagulationselektrode für Endoskope, insbesondere Kystoskope, die am okularseitigen. Ende durch einen Schrägstutzen in den Schaft einführbar und am objektivseitigen Ende herausgeführt und z. B. durch einen Albarranschen Hebel steuerbar ist.Coagulation Electrode for Endoscopes The invention relates to an I (oagulation electrode for endoscopes, especially cystoscopes, attached to the eyepiece. The end can be introduced into the shaft through an angled connector and on the lens side Led out and z. B. can be controlled by an Albarran lever.

Solche Kystoskope sind bisher so eingerichtet, daß heim Koagulieren von Gewebeteilen durch den Schaft eine Dauerspülung oder eine Wechselspülung vorgenommen werden kann, wenn Blutungen in der Blase zu einer Trübung der Blasenflüssigkeit führen, durch welche die Beleuchtung und Beobachtung verschlechtert oder sogar unmöglich gemacht werden kann. Die Spülung erfolgte dabei durch Anschluß des Geräte schaftes mittels absperrbarer Stutzen an entsprechende Zu- und Ableitungen, durch die eine klare Flüssigkeit über Kanäle im Schaftinnern in die Blase strömt und die trübe Flüssigkeit umgekehrt abgeleitet wird. Such cystoscopes have so far been set up so that at home coagulation continuous or alternating irrigation is carried out on tissue parts through the shaft If bleeding in the bladder can cause clouding of the bladder fluid lead, through which the lighting and observation worsened or even impossible can be made. The rinsing was done by connecting the device shaft by means of lockable nozzles to the corresponding inlets and outlets through which one clear liquid flows into the bladder through channels in the inside of the shaft and the cloudy Liquid is diverted the other way around.

Im allgeineinen wird dabei eine Wechselspülung vorgenommen, um getrennte Kanäle im Schaft, die zu einer Schaftverdickung führen, zu vermeiden. Die bisherige Spülungsart erfordert sehr lange Spülzeiten, da bei Trübungen der Blasenflüssigkeit bis zur völligen Klärung mindestens die gesamte Flüssigkeit der Blase erneuert werden muß.In general, an alternating rinse is carried out to separate Avoid channels in the shaft that lead to a thickening of the shaft. The previous The type of flushing requires very long flushing times because the bladder fluid is cloudy At least all of the fluid in the bladder must be renewed until it is completely clear got to.

Die Aufgabe der Erfindung besteht nun darin, bei Trübungen der Blasenflüssigkeit zumindest an den. zu koagul ierenden, unter Beobachtung stehenden Gewebestellen ständig eine klare Sicht für den Arzt zu erreichen. The object of the invention now consists in the case of turbidity of the bubble liquid at least to the. Tissue sites to be coagulated and under observation to achieve a clear view for the doctor at all times.

Zur Lösung dieser Aufgabe sind die hier in Frage kommenden Endoskope, insbesondere Kystoskope, erfindungsgemäß so ausgebildet, daß mit einem biegsamen, die Stromleitung aufnehmenden Spülschlauch ein Elektrodenkopf verbunden ist, der mit einer Axialdurchbohrung und/oder schräg von innen nach vorn außen verlaufenden feinen Bohrungen zum gerichteten Austritt von. durch den Spülschlauch zugeführter Spülflüssigkeit versehen ist. To solve this problem, the endoscopes in question are in particular cystoscopes, according to the invention designed so that with a flexible, the power line receiving the rinsing hose is connected to an electrode head with an axial bore and / or obliquely from the inside to the front outside fine bores for directed exit of. supplied through the flushing hose Rinsing liquid is provided.

Diese Elektrode mit dem die Stromleitung aufnehmenden Spülschlauch wird in üblicher Weise durch einen Schrägstutzen des Schaftes eingeführt und läuft am objektivseitigen. En.de z. B. über einen. Albarrauschen Hebel, durch den sie an die unter Beobachtung stehende, zu koagulierende Gewebestelle herangeführt wird. Der Arzt kann nun die Koagulation des betreffenden Gewebeteils durchführen und schaltet bei etwa auftretenden Blutungen die Spülung du.rch Offnung eines Hahnes ein, so daß die zu koagulierende Gewebestelle durch die auf sie gerichtete Spülung mittels klarer Flüssigkeit ständig klar sichtbar bleibt und es nicht mehr erforderlich ist, zu warten, bis durch die bisher übliche Spülung eine völlige Klärung der ganzen Blasenflüssigkeit vorgenommen ist. Der Arzt kann also ständig ohne Wartezeit arbeiten. Der Elektrodenkopf kann am freien Ende zur Erreichung einer großen Anlagefläche senkrecht oder schräg zur Elektrodenkopfachse abgeplattet sein, so daß ein glattes Anliegen des wirksamen Elektrode.n.teils an das zu kongulierende Gewebe erreicht wird. This electrode with the rinsing hose that holds the power line is introduced in the usual way through an angled connection piece of the shaft and runs on the lens side. En.de z. B. over a. Sea noise lever through which they is brought up to the tissue site to be coagulated that is under observation. The doctor can now carry out the coagulation of the relevant tissue part and switches If there is any bleeding, rinse by opening a tap, see above that the tissue site to be coagulated by means of the irrigation directed at it clear liquid remains clearly visible and it is no longer necessary to wait until the whole thing has been completely cleared up by the hitherto customary flushing Bladder fluid is made. Of the The doctor can therefore work constantly without waiting. The free end of the electrode head can be used to achieve a large contact surface be flattened perpendicular or at an angle to the electrode head axis, so that a smooth The effective electrode part reaches the tissue to be congulated will.

Besonders vorteilhaft ist es, den Elektrodenkopf als Zylinderrohr auszubilden, durch dessen Hohlraum die Spülflüssigkeit hindurchtreten kann sobald Blutungen auftreten. Dieser Rohrelektrodenkopf hat den besonderen Vorteil, daß er durch seine ringförmige Ausbildung das ganze zu koagulierende Gewebe umgibt, so daß ein.e verstärkte Koagulation durch Konzentrierung des Stromfeldes eintritt. Diese Wirkung wird sowohl bei gleichzeitiger Spülung als auch ohne Spülung erreicht, so daß dieser Gedanke auch für Elektroden anwendbar ist, die nicht an einem Spülschlauch angeschlossen sind, d. h., die etwa erforderliche Spülung wird in bekannter Weise vorgenommen. It is particularly advantageous to use the electrode head as a cylinder tube form, through the cavity of which the rinsing liquid can pass as soon as Bleeding occurs. This tube electrode head has the particular advantage that it surrounds the entire tissue to be coagulated due to its ring-shaped design, see above that increased coagulation occurs due to the concentration of the current field. This effect is achieved both with simultaneous flushing and without flushing, so that this idea can also be used for electrodes that are not connected to a rinsing hose are connected, d. That is, the rinsing required, if any, is carried out in a known manner performed.

Die Erfindung führt zu dem weiteren Vorteil, daß durch die Verbindung der Koagulationselektrode mit dem Spülschlauch und der gerichteten Spülung praktisch jedes bekannte Zystoskop mit Dauerspülung arbeiten kann, da lediglich erforderlich ist, die gleiche Flüssigkeitsmenge aus der Blase aZzunehmen, die zugeleitet wird, so daß also auch Geräte mit Wechselspülung nunmehr mit Dauerspülung arbeiten können In der Zeichnung ist ein Ausführungsbeispiel der Koagulationselektrode nach der Erfindung dargestellt, und zwar zeigt Fig. 1 eine perspektivische Ansicht der Koagulationselektrode, Fig. 2 eine abgeänderte Ausführung des Elektrodenkopfes in perspektivischer Ansicht, Fig. 3 einen Achsschnitt durch den Elektrodenkopf der Ausführung nach Fig. 1, Fig. 4 einen Achsschnitt durch einen abgeänderten Elektrodenkopf, Fig. 5 einen Achsschnitt durch einen Elektrodenkopf ohne gerichtete Spülung. The invention leads to the further advantage that through the connection the coagulation electrode with the irrigation hose and the directed irrigation are practical every known cystoscope can work with continuous irrigation, as only required is to take the same amount of fluid from the bladder aZ that is supplied, so that devices with alternating flushing can now also work with continuous flushing In the drawing is an embodiment of the coagulation electrode according to Invention shown, namely Fig. 1 shows a perspective view of the coagulation electrode, 2 shows a modified embodiment of the electrode head in a perspective view, 3 shows an axial section through the electrode head of the embodiment according to FIG. 1, FIG. 4 shows an axial section through a modified electrode head, Fig. 5 shows an axial section through an electrode head without directional flushing.

Nach dem Ausführungsbeispiel handelt es sich im Fall der Erfindung um eine Koagulationseiektrode für Endoskope, insbesondere Kystoskope, die am okular seitigen Ende des Gerätes durch einen Schrägstutzen in den Schaft eingeführt und am objekrivseitigen Ende z. B. über einen Albarrnnschen Hebel, durch den die Elektrode an. jede beliebige gewünschte Stelle herangebracht werden kann, herausgeführt wird. According to the embodiment, it is in the case of the invention a coagulation electrode for endoscopes, especially cystoscopes, which are attached to the eyepiece side end of the device is introduced into the shaft through an angled connector and at the lens end z. B. via an Albarrnn lever through which the electrode at. any desired location can be brought up.

Die Elektrode nach der Erfindung besteht aus einem Elektrodenkopf 1, der mit einem Spülsclllauch 2 aus Isoliermaterial verb,un.denl ist und durch den die Stromleitung 3 hindurchgeführt ist, die einerseits an die Spannungsquelle und andererseits an den Elek trodenkopf 1 geführt ist. Der Spülschlauch 2 mündet in ein Hand stück 4, welches am Vorderende mit einem Stutzen 5 zum Aufschieben einer Schlauchleitung 6 versehen ist, durch die Spülflüssigkeit, z. B. Wasser, durch den Spülschlauch 2 zum Elektrodenkopf 1 zugeführt wird. The electrode according to the invention consists of an electrode head 1, which is connected to a rinsing hose 2 made of insulating material and is through which the power line 3 is passed through, on the one hand to the voltage source and on the other hand to the electrode head 1 is performed. The rinsing hose 2 opens in a hand piece 4, which at the front end with a nozzle 5 for pushing a Hose line 6 is provided, through the flushing liquid, for. B. water through the Rinsing hose 2 is fed to the electrode head 1.

Nach Fig. 1 und 3 ist der Elektrodenkopf 1 mit schräg von innen nach vorn außen verlaufenden feinen Bohrungen 7 versehen, durch welche die Spülflüssigkeit austreten kann. Solange der Elektrodenkopf 1 trocken ist, tritt d.ie Spülflüssigkeit durch die Bohrung 7 in deren Achsrichtung aus. Ist die Elektrode jedoch in die Blase eingeführt, so wird auch die Außenfläche des Elektrodenkopfes benetzt, und durch diese Benetzung legen. sich die austretenden Flüssigkeitsstrahlen an. das freie Ende des Elektrodenkopfumfanges an un.d ergeben somit einen Spülflüssigkeitsschleier in Form eines Zylinderringes. Die Spülung wird lediglich dann vorgenommen, wenn. durch das Arbeiten mit der Elektrode 1 zur Koagulierung von Gewebeteilen Blutungen auftreten, durch die eine Trübung der Blasenflüssigkeit eintritt, welche eine klare Sicht durch die Optik verhindert. Tritt eine solche Blutung auf, so wird die Spülung durch C nung eines Hahnes eingeschaltet und gegen. die. zu koagulierende Stelle gerichtet, so daß der Arzt nunmehr in bezug auf diese Stelle ständig eine klare Sicht gewinnt. According to Fig. 1 and 3, the electrode head 1 is inclined from the inside to fine bores 7 running outward at the front, through which the flushing liquid can emerge. As long as the electrode head 1 is dry, the rinsing liquid occurs through the bore 7 in the axial direction thereof. However, the electrode is in the bladder introduced, the outer surface of the electrode head is also wetted, and through put this wetting. the exiting liquid jets. the free The end of the electrode head circumference at and d thus result in a rinsing liquid curtain in the form of a cylinder ring. Rinsing is only carried out when. by working with the electrode 1 to coagulate tissue parts bleeding occur through which a cloudiness of the bladder fluid occurs, which a clear Obstructed view through the optics. If such bleeding occurs, then the irrigation becomes turned on by turning a tap and against. the. site to be coagulated directed so that the doctor now always has a clear reference to this point Sight wins.

Entsprechend Fig. 4 kann der Elektrodenkopf 1 auch mit einer axialen. Durchbohrung 8 versehen. sein., durch welche die Spülflüssigkeit in. Achsrichtung austritt und damit ebenfalls zu einer klaren Sicht an der zu koagulierenden Stelle führt. According to FIG. 4, the electrode head 1 can also have an axial. Provided through hole 8. be., through which the rinsing liquid in. Axial direction emerges and thus also to a clear view of the area to be coagulated leads.

Man kann den Elektrodenkopf weiter entsprechend Fig. 2 sowohl mit einer Axialbohrung 8 als auch mit den vorerwähnten Schrägbohrungen 7 versehen, so daß sowohl vor Anlage des Elektrodenkopfendes an das zu koagulierende Gewebe als auch nach Anlage an das Gewebe eine Spülung und damit eine freie Sicht für den Arzt ermöglicht wird. You can continue to use the electrode head according to FIG an axial bore 8 and provided with the aforementioned inclined bores 7, so that both before the end of the electrode head rests on the tissue to be coagulated and rinsing after contact with the tissue and thus a clear view for the doctor will.

Das freie Ende des Elektrodenkopfes 1 ist zur Erzielung einer größeren. Anlagefläche an das zu koagulierende Gewebe senkrecht oder schräg zur Elektrodenkopfachs e abgeflacht. The free end of the electrode head 1 is to achieve a larger. Contact surface on the tissue to be coagulated perpendicular or at an angle to the electrode head compartment e flattened.

Die ringförmige zylindrische Ausbildung des Elektrodeukopfes entsprechend Fig. 4 hat den besonderen Vorteil, daß der zu koagulierende Gewebeteil von. dem Elektrodenring umgeben ist, so daß hierdurch eine verstärkte Koagulation erreichbar ist, da das Strom bzw. Spannungsfeld der Elektrode im Innern des zylinderringförmigen Kopfes konzentriert wird. Eine solche Elektrodenform zur verstärkten Koagulation ist in Fig. 5 ohne eine Spülmöglichkeit im vorerwähnten Sinn dargestellt. Es ist aber auch möglich, in diesem Fall zusätzlich die axiale Bohrung als auch die Schrägbohrungen vorzusehen,. Ist keine Spülungsmöglichkeit vorhanden, so. muß die Spülung bei auftretenden. Trübungen, der Blasenflüssigkeit in üblicher Weise vorgenommen werden. The ring-shaped cylindrical design of the electric deuce head accordingly Fig. 4 has the particular advantage that the tissue to be coagulated from. to the Electrode ring is surrounded, so that thereby an increased coagulation can be achieved is because the current or voltage field of the electrode inside the cylindrical ring-shaped Head is concentrated. Such an electrode shape for increased coagulation is shown in Fig. 5 without a flush option in the aforementioned sense. It is but also possible, in this case additionally the axial bore and the inclined bores to provide. If there is no possibility of flushing, then so. must flush when occurring. Turbidity of the bladder fluid can be made in the usual way.
