Koagulationselektrode für Endoskope Die Erfindung bezieht sich aufeine I(oagulationselektrode für Endoskope, insbesondere Kystoskope, die am okularseitigen.Ende durch einen Schrägstutzen in den Schaft einführbar und am objektivseitigenEnde herausgeführt und z. B. durch einen Albarranschen Hebel steuerbar ist.Coagulation Electrode for Endoscopes The invention relates toan 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 sideLed out and z. B. can be controlled by an Albarran lever.
Solche Kystoskope sind bisher so eingerichtet, daß heim Koagulierenvon Gewebeteilen durch den Schaft eine Dauerspülung oder eine Wechselspülung vorgenommenwerden kann, wenn Blutungen in der Blase zu einer Trübung der Blasenflüssigkeitführen, durch welche die Beleuchtung und Beobachtung verschlechtert oder sogar unmöglichgemacht werden kann. Die Spülung erfolgte dabei durch Anschluß des Geräte schaftesmittels absperrbarer Stutzen an entsprechende Zu- und Ableitungen, durch die eineklare Flüssigkeit über Kanäle im Schaftinnern in die Blase strömt und die trübeFlüssigkeit umgekehrt abgeleitet wird. Such cystoscopes have so far been set up so that at home coagulationcontinuous or alternating irrigation is carried out on tissue parts through the shaftIf bleeding in the bladder can cause clouding of the bladder fluidlead, through which the lighting and observation worsened or even impossiblecan be made. The rinsing was done by connecting the device shaftby means of lockable nozzles to the corresponding inlets and outlets through which oneclear liquid flows into the bladder through channels in the inside of the shaft and the cloudyLiquid is diverted the other way around.
Im allgeineinen wird dabei eine Wechselspülung vorgenommen, um getrennteKanäle im Schaft, die zu einer Schaftverdickung führen, zu vermeiden. Die bisherigeSpülungsart erfordert sehr lange Spülzeiten, da bei Trübungen der Blasenflüssigkeitbis zur völligen Klärung mindestens die gesamte Flüssigkeit der Blase erneuert werdenmuß.In general, an alternating rinse is carried out to separateAvoid channels in the shaft that lead to a thickening of the shaft. The previousThe type of flushing requires very long flushing times because the bladder fluid is cloudyAt least all of the fluid in the bladder must be renewed until it is completely cleargot to.
Die Aufgabe der Erfindung besteht nun darin, bei Trübungen der Blasenflüssigkeitzumindest an den. zu koagul ierenden, unter Beobachtung stehenden Gewebestellenständig eine klare Sicht für den Arzt zu erreichen. The object of the invention now consists in the case of turbidity of the bubble liquidat least to the. Tissue sites to be coagulated and under observationto 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, dermit einer Axialdurchbohrung und/oder schräg von innen nach vorn außen verlaufendenfeinen Bohrungen zum gerichteten Austritt von. durch den Spülschlauch zugeführterSpülflüssigkeit versehen ist. To solve this problem, the endoscopes in question arein particular cystoscopes, according to the invention designed so that with a flexible,the power line receiving the rinsing hose is connected to an electrode headwith an axial bore and / or obliquely from the inside to the front outsidefine bores for directed exit of. supplied through the flushing hoseRinsing liquid is provided.
Diese Elektrode mit dem die Stromleitung aufnehmenden Spülschlauchwird in üblicher Weise durch einen Schrägstutzen des Schaftes eingeführt und läuftam objektivseitigen. En.de z. B. über einen. Albarrauschen Hebel, durch den siean die unter Beobachtung stehende, zu koagulierende Gewebestelle herangeführt wird.Der Arzt kann nun die Koagulation des betreffenden Gewebeteils durchführen und schaltetbei etwa auftretenden Blutungen die Spülung du.rch Offnung eines Hahnes ein, sodaß die zu koagulierende Gewebestelle durch die auf sie gerichtete Spülung mittelsklarer Flüssigkeit ständig klar sichtbar bleibt und es nicht mehr erforderlich ist,zu warten, bis durch die bisher übliche Spülung eine völlige Klärung der ganzenBlasenflüssigkeit vorgenommen ist. DerArzt kann also ständig ohne Wartezeit arbeiten.Der Elektrodenkopf kann am freien Ende zur Erreichung einer großen Anlageflächesenkrecht oder schräg zur Elektrodenkopfachse abgeplattet sein, so daß ein glattesAnliegen des wirksamen Elektrode.n.teils an das zu kongulierende Gewebe erreichtwird. This electrode with the rinsing hose that holds the power lineis introduced in the usual way through an angled connection piece of the shaft and runson the lens side. En.de z. B. over a. Sea noise lever through which theyis 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 switchesIf there is any bleeding, rinse by opening a tap, see abovethat the tissue site to be coagulated by means of the irrigation directed at itclear liquid remains clearly visible and it is no longer necessaryto wait until the whole thing has been completely cleared up by the hitherto customary flushingBladder fluid is made. Of theThe doctor can therefore work constantly without waiting.The free end of the electrode head can be used to achieve a large contact surfacebe flattened perpendicular or at an angle to the electrode head axis, so that a smoothThe effective electrode part reaches the tissue to be congulatedwill.
Besonders vorteilhaft ist es, den Elektrodenkopf als Zylinderrohrauszubilden, durch dessen Hohlraum die Spülflüssigkeit hindurchtreten kann sobaldBlutungen auftreten. Dieser Rohrelektrodenkopf hat den besonderen Vorteil, daß erdurch seine ringförmige Ausbildung das ganze zu koagulierende Gewebe umgibt, sodaß 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 Spülschlauchangeschlossen sind, d. h., die etwa erforderliche Spülung wird in bekannter Weisevorgenommen. It is particularly advantageous to use the electrode head as a cylinder tubeform, through the cavity of which the rinsing liquid can pass as soon asBleeding occurs. This tube electrode head has the particular advantage that itsurrounds the entire tissue to be coagulated due to its ring-shaped design, see abovethat 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 hoseare connected, d. That is, the rinsing required, if any, is carried out in a known mannerperformed.
Die Erfindung führt zu dem weiteren Vorteil, daß durch die Verbindungder Koagulationselektrode mit dem Spülschlauch und der gerichteten Spülung praktischjedes bekannte Zystoskop mit Dauerspülung arbeiten kann, da lediglich erforderlichist, die gleiche Flüssigkeitsmenge aus der Blase aZzunehmen, die zugeleitet wird,so daß also auch Geräte mit Wechselspülung nunmehr mit Dauerspülung arbeiten könnenIn der Zeichnung ist ein Ausführungsbeispiel der Koagulationselektrode nach derErfindung 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 connectionthe coagulation electrode with the irrigation hose and the directed irrigation are practicalevery known cystoscope can work with continuous irrigation, as only requiredis 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 flushingIn the drawing is an embodiment of the coagulation electrode according toInvention 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 Erfindungum eine Koagulationseiektrode für Endoskope, insbesondere Kystoskope, die am okularseitigen Ende des Gerätes durch einen Schrägstutzen in den Schaft eingeführt undam objekrivseitigen Ende z. B. über einen Albarrnnschen Hebel, durch den die Elektrodean. jede beliebige gewünschte Stelle herangebracht werden kann, herausgeführt wird. According to the embodiment, it is in the case of the inventiona coagulation electrode for endoscopes, especially cystoscopes, which are attached to the eyepieceside end of the device is introduced into the shaft through an angled connector andat the lens end z. B. via an Albarrnn lever through which the electrodeat. any desired location can be brought up.
Die Elektrode nach der Erfindung besteht aus einem Elektrodenkopf1, der mit einem Spülsclllauch 2 aus Isoliermaterial verb,un.denl ist und durchden die Stromleitung 3 hindurchgeführt ist, die einerseits an die Spannungsquelleund andererseits an den Elek trodenkopf 1 geführt ist. Der Spülschlauch 2 mündetin ein Hand stück 4, welches am Vorderende mit einem Stutzen 5 zum Aufschieben einerSchlauchleitung 6 versehen ist, durch die Spülflüssigkeit, z. B. Wasser, durch denSpülschlauch 2 zum Elektrodenkopf 1 zugeführt wird. The electrode according to the invention consists of an electrode head1, which is connected to a rinsing hose 2 made of insulating material and is throughwhich the power line 3 is passed through, on the one hand to the voltage sourceand on the other hand to the electrode head 1 is performed. The rinsing hose 2 opensin a hand piece 4, which at the front end with a nozzle 5 for pushing aHose line 6 is provided, through the flushing liquid, for. B. water through theRinsing hose 2 is fed to the electrode head 1.
Nach Fig. 1 und 3 ist der Elektrodenkopf 1 mit schräg von innen nachvorn außen verlaufenden feinen Bohrungen 7 versehen, durch welche die Spülflüssigkeitaustreten kann. Solange der Elektrodenkopf 1 trocken ist, tritt d.ie Spülflüssigkeitdurch die Bohrung 7 in deren Achsrichtung aus. Ist die Elektrode jedoch in die Blaseeingeführt, so wird auch die Außenfläche des Elektrodenkopfes benetzt, und durchdiese Benetzung legen. sich die austretenden Flüssigkeitsstrahlen an. das freieEnde des Elektrodenkopfumfanges an un.d ergeben somit einen Spülflüssigkeitsschleierin Form eines Zylinderringes. Die Spülung wird lediglich dann vorgenommen, wenn.durch das Arbeiten mit der Elektrode 1 zur Koagulierung von Gewebeteilen Blutungenauftreten, durch die eine Trübung der Blasenflüssigkeit eintritt, welche eine klareSicht durch die Optik verhindert. Tritt eine solche Blutung auf, so wird die Spülungdurch C nung eines Hahnes eingeschaltet und gegen. die. zu koagulierende Stellegerichtet, so daß der Arzt nunmehr in bezug auf diese Stelle ständig eine klareSicht gewinnt. According to Fig. 1 and 3, the electrode head 1 is inclined from the inside tofine bores 7 running outward at the front, through which the flushing liquidcan emerge. As long as the electrode head 1 is dry, the rinsing liquid occursthrough the bore 7 in the axial direction thereof. However, the electrode is in the bladderintroduced, the outer surface of the electrode head is also wetted, and throughput this wetting. the exiting liquid jets. the freeThe end of the electrode head circumference at and d thus result in a rinsing liquid curtainin the form of a cylinder ring. Rinsing is only carried out when.by working with the electrode 1 to coagulate tissue parts bleedingoccur through which a cloudiness of the bladder fluid occurs, which a clearObstructed view through the optics. If such bleeding occurs, then the irrigation becomesturned on by turning a tap and against. the. site to be coagulateddirected so that the doctor now always has a clear reference to this pointSight wins.
Entsprechend Fig. 4 kann der Elektrodenkopf 1 auch mit einer axialen.Durchbohrung 8 versehen. sein., durch welche die Spülflüssigkeit in. Achsrichtungaustritt und damit ebenfalls zu einer klaren Sicht an der zu koagulierenden Stelleführt. 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 directionemerges and thus also to a clear view of the area to be coagulatedleads.
Man kann den Elektrodenkopf weiter entsprechend Fig. 2 sowohl miteiner Axialbohrung 8 als auch mit den vorerwähnten Schrägbohrungen 7 versehen, sodaßsowohl vor Anlage des Elektrodenkopfendes an das zu koagulierende Gewebe als auchnach Anlage an das Gewebe eine Spülung und damit eine freie Sicht für den Arzt ermöglichtwird. You can continue to use the electrode head according to FIGan axial bore 8 and provided with the aforementioned inclined bores 7, sothatboth before the end of the electrode head rests on the tissue to be coagulated andrinsing after contact with the tissue and thus a clear view for the doctorwill.
Das freie Ende des Elektrodenkopfes 1 ist zur Erzielung einer größeren.Anlagefläche an das zu koagulierende Gewebe senkrecht oder schräg zur Elektrodenkopfachse 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 compartmente flattened.
Die ringförmige zylindrische Ausbildung des Elektrodeukopfes entsprechendFig. 4 hat den besonderen Vorteil, daß der zu koagulierende Gewebeteil von. demElektrodenring umgeben ist, so daß hierdurch eine verstärkte Koagulation erreichbarist, da das Strom bzw. Spannungsfeld der Elektrode im Innern des zylinderringförmigenKopfes konzentriert wird. Eine solche Elektrodenform zur verstärkten Koagulationist in Fig. 5 ohne eine Spülmöglichkeit im vorerwähnten Sinn dargestellt. Es istaber auch möglich, in diesem Fall zusätzlich die axiale Bohrung als auch die Schrägbohrungenvorzusehen,. 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 accordinglyFig. 4 has the particular advantage that the tissue to be coagulated from. to theElectrode ring is surrounded, so that thereby an increased coagulation can be achievedis because the current or voltage field of the electrode inside the cylindrical ring-shapedHead is concentrated. Such an electrode shape for increased coagulationis shown in Fig. 5 without a flush option in the aforementioned sense. It isbut also possible, in this case additionally the axial bore and the inclined boresto 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.
