Abstract

Coloscopes fitted with this system are no longer pushed but can be drawn further into the region to be examined after their introduction. For this, a mechanically displaceable system (principal system) is located on the coloscope shaft behind the controllable tip. It comprises an inflatable or ventable group of balloons (balloon) on a flexible sliding pipe. If required, the system may be supplemented by a group of balloons (balloon) firmly mounted on the coloscope shaft (auxiliary system). Considerable practical advantages result for diagnosis and therapy. Without the disadvantages of the conventional, pushed instruments (considerable time expenditure, assistant, radiological control, large problems in the regions known to be critical (sigmoid ..) and the associated pain) the doctor can pass unaided even through difficult regions without any problems while he controls the passage via the optical system and the movable tip. In addition, he can treat the patient alone with accurate control.

Description

Die Erfindung betrifft en auf dem Schaft des Coloskops (S) mechanisch verschiebbares System (1; 1′). Es besteht aus einer aufblasbaren bzw. zu entlüftenden Ballongruppe (Ballon) auf einem flexiblen Gleitrohr (Hauptsystem).The invention relates to a mechanically displaceable system ( 1; 1 ' ) on the shaft of the coloscope ( S ). It consists of an inflatable or deflated balloon group (balloon) on a flexible slide tube (main system).

Dieses System kann bei Bedarf durch eine auf dem Coloskopschaft fest montierte Ballongruppe (Ballon) ergänzt werden (Hilfssystem (2; 2′)).If necessary, this system can be supplemented by a balloon group (balloon) permanently mounted on the colonoscope shaft (auxiliary system ( 2; 2 ′ )).

Das Manipulationssystem soll den Gebrauch von Coloskopen dadurch grundlegend verändern, daß diese nicht wie seither in den Untersuchungsbereich geschoben werden, sondern nach Einführen in diesen hineingezogen werden.The manipulation system is said to use coloscopes fundamentally change that these are not as pushed since then into the examination area but are drawn into it after insertion will.

Die seither gebräuchlichen Geräte werden geschoben (Deutsche Patentschriften der Gruppen Endoskope, Rektoskope, Hohlsonden). Sie verlangen einen erheblichen Zeitaufwand, meist Röntgenkontrolle und bereiten den Patienten z. T. erhebliche Schmerzen, weil geschobene Coloskope Bögen und S-Bögen nur schwer überwinden können. Der Arzt bedient in der Regel nur die heute meist steuerbare Coloskopspitze (CS) und ist für Vor- und Rückwärtsbewegungen weitgehend auf eine Hilfsperson angewiesen.The devices that have been in use since then are pushed (German patents of the groups endoscopes, rectoscopes, hollow probes). They require a considerable amount of time, usually X-ray control, and prepare the patient e.g. T. considerable pain because pushed coloscopes and S-arches are difficult to overcome. The doctor usually only operates the mostly controllable coloscope tip ( CS ) and is largely dependent on an assistant for forward and backward movements.

Rein pneumatische oder mechanische Manipulationssysteme, die z. B. durch erzeugte Wellenbewegung Vorschub erzeugen sollen, haben sich in der Praxis nicht durchgesetzt.
Purely pneumatic or mechanical manipulation systems, e.g. B. should generate feed by generated wave motion, have not prevailed in practice.

Der Erfindung liegt die Aufgabe zugrunde, die Untersuchung mit Coloskopen dadurch für alle Beteiligten zu vereinfachen, daß der Arzt mit Hilfe des mechanisch- pneumatischen Systems das Coloskop in Takten in den zu untersuchenden Bereich hineinziehen kann.The invention has for its object the investigation with coloscopes for everyone involved to simplify that the doctor with the help of the mechanical pneumatic system to the coloscope in cycles examining area.

Die Aufgabe wird erfindungsmäßig dadurch gelöst, daß sich auf dem Schaft (S) des Coloskops hinter der steuerbaren Spitze (CS) ein mechanisch verschiebbares System befindet (Hauptsystem). Es besteht aus einer aufblasbaren bzw. zu entlüftenden Ballongruppe (Ballon) auf einem flexiblen Gleitrohr (R).The object is achieved according to the invention in that a mechanically displaceable system is located on the shaft ( S ) of the coloscope behind the controllable tip ( CS ) (main system). It consists of an inflatable or deflated balloon group (balloon) on a flexible slide tube ( R ).

Das System kann bei Bedarf durch eine auf dem Coloskopschaft fest montierte Ballongruppe (Ballon) ergänzt werden (Hilfssystem (2, 2′)).If necessary, the system can be supplemented by a balloon group (balloon) fixed to the colonoscope shaft (auxiliary system ( 2, 2 ′ )).

Die Ballons aus hochflexiblem Material liegen in entlüftetem Zustand fest auf dem Gleitrohr bzw. dem Coloskopschaft an. Aufgeblasen halten sie das Gleitrohr (R) bzw. das Coloskop (S) fest, indem sie sich in der Umgebung abstützen.When deflated, the balloons made of highly flexible material lie firmly on the slide tube or the coloscope shaft. When inflated, hold on to the sliding tube ( R ) or the coloscope ( S ) by leaning against the surroundings.

Ist die Ballongruppe (Ballon) des Hauptsystems aufgeblasen (1), stützt sie es in der Umgebung ab u. der Schaft des Coloskops kann mit Hilfe einer Mechanik vor- oder zurückbewegt werden.If the balloon group (balloon) of the main system is inflated ( 1 ), it supports it in the area and the shaft of the coloscope can be moved forward or back with the help of a mechanism.

Die fest montierte Ballongruppe (Ballon), das Hilfssystem (2), ist während dieses Vorgangs ganz oder teilweise entlüftet (Fig. 1).The permanently mounted group of balloons (balloon), the auxiliary system ( 2 ), is completely or partially vented during this process ( Fig. 1).

Soll nach diesem Arbeitstakt das Hauptsystem durch die Mechanik in eine neue Position gebracht werden, wird seine Ballongruppe (Ballon) zunächst ganz oder teilweise entlüftet (1′). Während dieses Zwischentaktes kann das Coloskop je nach Bedarf von der aufgeblasenen Ballongruppe (Ballon) des Hilfssystems (2′) gehalten bzw. abgestützt werden. (Fig. 2)If after this work cycle the main system is to be moved into a new position by the mechanics, its balloon group (balloon) is first completely or partially deflated ( 1 ′ ). During this intermediate cycle, the coloscope can be held or supported as required by the inflated balloon group (balloon) of the auxiliary system ( 2 ' ). ( Fig. 2)

Während der Therapie kann die aufgeblasene Ballongruppe des Hauptsystems (1) die steuerbare Instrumentenspitze stützen und erlaubt dem Therapeuten eine genaue Manipulation der Instrumente (Fig. 1).During therapy, the inflated balloon group of the main system ( 1 ) can support the controllable instrument tip and allows the therapist to manipulate the instruments precisely ( Fig. 1).

Die Ballongruppen (Ballons) können z. B. über (Magnet-) Ventile aus dem Luft-(CO2) bzw. in das Vakuumsystem aufgeblasen (Druckbegrenzer) und entlüftet werden.The balloon groups (balloons) can e.g. B. via (solenoid) valves from the air (CO 2 ) or into the vacuum system (pressure limiter) and vented.

Die Ballongruppe (Ballon) des Hauptsystems (1, 1′) kann z. B. über eine längenflexible Verbindung an das Druck- und Vakuumsystem angeschlossen werden (4′).The balloon group (balloon) of the main system ( 1, 1 ' ) can, for. B. connected via a flexible connection to the pressure and vacuum system ( 4 ' ).

Das Hauptsystem (1, 1′) wird über einen Zug (4) von Hand oder einen Motor gezogen und geschoben.The main system ( 1, 1 ' ) is pulled and pushed by hand via a train ( 4 ) or a motor.

Die Enden des Zugs und der Luft-Vakuumverbindung verlaufen in offenen Kanälen (3) im Coloskopschaft (S) unter dem Gleitrohr (R) des Hauptsystems (1, 1′), mit dem sie verbunden sind. Die Länge dieser Kanäle bestimmt die maximale Strecke der Arbeits- bzw. Zwischentaktes (H).The ends of the train and the air-vacuum connection run in open channels ( 3 ) in the coloscope shaft ( S ) under the slide tube ( R ) of the main system ( 1, 1 ' ) with which they are connected. The length of these channels determines the maximum distance of the work or intermediate cycle ( H ).

Die mit dieser Erfindung erzielten Vorteile bestehen insbesondere darin, daß nicht wie seither das Gerät meist unter Beteiligung einer Hilfsperson durch Schieben sehr umständlich in den zu untersuchenden Bereich hineinmanipuliert werden muß, was mit erheblichem Zeitaufwand, Röntgenkontrolle und großen Schmerzen für den Patienten verbunden ist.The advantages achieved with this invention are especially in that not since then the device usually with the help of an auxiliary person by pushing manipulated very laboriously into the area to be examined must be, which takes a considerable amount of time, X-ray control and great pain for the Patient is connected.

Nachdem die Coloskopspitze und das entlüftete Hauptsystem eingeführt sind, kann der Arzt jetzt selbständig das Coloskop in Takten zügig in den zu untersuchenden Bereich hineinziehen. Dabei steuert er das Coloskop über Optik und bewegliche Spitze und kann so auch seither schwierige Abschnitte problemlos durchfahren. Außerdem kann er alleine genau steuernd therapieren.After the coloscope tip and the deflated main system are introduced, the doctor can now work independently the coloscope quickly in bars in the ones to be examined Drag area. He controls the coloscope about optics and movable tip and has been able to do so ever since drive through difficult sections without any problems. In addition, he can provide precise control therapy alone.
