Abstract
Description
Die Erfindung bezieht sich auf ein Operationsinstrument zum Einführen von medizinischen Instrumenten in das Körperinnere eines Patienten, mit einem Ventilkörper und einer Hülse, die einen Durchtrittskanal umschließen, in dem das Instrument axial verschiebbar ist, wobei der Durchtrittskanal mittels einer Klappe verschließbar ist. Diese Konstruktion dient der Abdichtung des erhöhten Gasdruckes im Bauchraum, dem s.g. Pneumperitoneum.The invention relates to a surgical instrument for Introducing medical instruments into the interior of a body Patient, with a valve body and a sleeve, the one Enclose passage channel in which the instrument axially is displaceable, the passage channel by means of a flap is lockable. This construction serves to seal the increased gas pressure in the abdomen, the so-called Pneumperitoneum.
Diese vorbekannten Operationsinstrumente haben jedoch den Nachteil, daß das Sperr- oder Reiberventil des Gas-Zufuhrstutzens oder der Klappenmechanismus der Verschlußklappe zahlreiche, teilweise auch korrosionsanfällige Kleinteile, wie Schenkelfedern, Schrauben, Bolzen oder dergleichen aufweist, die das Reinigen des Instrumentes erheblich erschweren. Zum vollständigen Sterilisieren des Instrumentes muß der Klappenmechanismus und das Reiberventil des Gas-Zufuhrstutzens demontiert werden. Dies ist jedoch in einem Krankenhausbetrieb oder in einer Arztpraxis kaum möglich, da hierfür Spezialwerkzeuge benötigt werden und da insbesondere beim Lösen oder Einsetzen der Halteschrauben für die Rückstellfeder der Verschlußklappe die Gefahr besteht, daß die Halteschrauben, Bolzen oder dergleichen Kleinteile verloren gehen.However, these known surgical instruments have the disadvantage that that the shut-off or friction valve of the gas supply nozzle or Flap mechanism of the closure flap numerous, partly also small parts susceptible to corrosion, such as leg springs, screws, Has bolts or the like that the cleaning of the instrument complicate considerably. To completely sterilize the The valve mechanism and the friction valve of the Gas supply nozzle to be dismantled. However, this is in one Hospital operation or in a doctor's office hardly possible because special tools are needed for this and especially when Loosen or insert the retaining screws for the return spring of the Closure flap there is a risk that the retaining screws, bolts or similar small parts get lost.
Gerade der Verschluß der Gaszuführung wird bei allen bekannten
Konstruktionen entweder durch einen Hahn oder eine Verschlußkappe
verschlossen. Dies bedeutet jedoch zusätzlichen Reinigungsaufwand
und Lagerhaltung. Auch sind zusätzliche Bauteile erforderlich, die
die Schwester vor der Operation richtet. Bei Erfordernis des
Gasanschlusses ist ein Wechsel des Trokares erforderlich
Es sind auch bereits Einweg-Operationsinstrumente bekannt, die für
einen einmaligen Gebrauch bestimmt sind. Dies ist jedoch mit einem
erheblichen Kostenaufwand verbunden und erscheint insbesondere auch
aus ökologischen Gründen nicht sinnvoll.
The closure of the gas supply is closed in all known constructions either by a tap or a cap. However, this means additional cleaning and storage. Additional components are also required, which the nurse directs before the operation. If the gas connection is required, the trocar must be changed
Disposable surgical instruments that are intended for single use are also known. However, this is associated with considerable expense and does not appear to make sense, particularly for ecological reasons.
Es besteht deshalb die Aufgabe, in Operationsinstrument der eingangs erwähnten Art zu schaffen, das leicht zu reinigen und zu sterilisieren ist. Dabei soll der Arzt leicht den Gasanschluß öffnen oder verschließen können, ohne die Operation zu stören.There is therefore the task in the surgical instrument to create the kind mentioned above that is easy to clean and to is sterilize. The doctor should easily connect the gas can open or close without interfering with the operation.
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Operationsinstrument der eingangs erwähnten Art insbesondere darin, daß der Schaft des Trokares vom Ventilkörper trennbar mit einer Schraubenmutter oder dergleichen verbunden ist. Durch die Länge der Verbindungsfläche wird Dichtigkeit erreicht, da diese Verbindung in Einführungsrichtung hinter der Verschlußklappe liegt. Ein Überström-Kanal zum Gasanschluß kann aus jeweils mindestens einer Einbohrung in die Verbindungsfläche am Ventilkörper als auch am Schaft durch Verdrehen gebildet werden. Zuströmseitig kann ein olivenartiger Ansatzstutzen aus dem Ventilkörper ragen, der mit einem Schlauch oder dergleichen mit dem Gas-Anschluß verbunden werden kann. Durch eine Vorrichtung an Ventilkörper und Schaft kann die freie gegenseitige Verdrehbarkeit aufgehoben und in mindestens 2 vorgegebenen Stellungen fixiert werden. Dies können ausgefräßte Nuten einerseits und sich dort verrastende Stifte anderseits sein. Auch kann vorteilhaft durch die äußere Form des Schaftes im Verbindungsbereich die Verdrehung verhindert werden. Dadurch ist vorteilhaft durch eine einfache Lösung der Schraubverbindung und gegenläufige Verdrehung von Ventilkörper und Schaft der Überströmkanal zu öffnen oder zu schließen.The inventive solution to this problem consists in the Surgical instrument of the type mentioned at the outset, in particular in that the stem of the trocar is separable from the valve body with a Screw nut or the like is connected. By the length of the Connection surface tightness is achieved because this connection in Direction of insertion is behind the flap. On Overflow channel for gas connection can consist of at least one Drilling in the connecting surface on the valve body as well as on Shaft can be formed by twisting. On the upstream side, a protruding olive-like connecting piece from the valve body with a hose or the like connected to the gas connector can be. Through a device on the valve body and stem free reversibility and in at least 2 predetermined positions can be fixed. You can milled grooves on the one hand and locking pins there be different. Can also be advantageous due to the outer shape of the Shaft in the connection area the rotation can be prevented. This is advantageous through a simple solution Screw connection and counter-rotation of the valve body and Open or close the shaft of the overflow channel.
Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen näher erläutert.Below is an embodiment of the invention based on the Drawings explained in more detail.
Es zeigen in unterschiedlichen Maßstäben und zum Teil stark schematisiert:They show on different scales and some are strong schematized:
Fig. 1 eine Seitenansicht eines Operationsinstrumentes mit einer Verschlußklappe, die aus der Schließstellung geschwenkt ist und einem Gaszuströmkanal als Einbohrung in die Verbindungsfläche an Ventilkörper und Schaft Fig. 1 is a side view of a surgical instrument with a closure flap which is pivoted out of the closed position and a gas inflow channel as a hole in the connecting surface on the valve body and stem
Fig. 2 eine Aufsicht auf die Verbindungsfläche von Ventilkörper und Schaft in 2 Verdrehstellungen. Fig. 2 is a plan view of the connecting surface of the valve body and stem in 2 rotational positions.
Fig. 3 die Vorrichtung zur Aufhebung der freien Verdrehbarkeit von Ventilkörper und Schaft. Fig. 3 shows the device for canceling the free rotatability of the valve body and stem.
In Fig. 1 ist ein Operationsinstrument T zum Einführen von medizinischen Instrumenten in das Körperinnere eines Patienten dargestellt, das einen Ventilkörper V und eine Hülse H aufweist, die einen Durchtrittskanal DK umschließen. Der Durchtrittskanal DK einer Verschlußklappe VK gasdicht verschließbar, die beim Einführen des Instrumentes aus einer Schließstellung in eine Offenstellung verschwenkbar ist. Durch die Einbohrungen BV im Ventilkörper und BH in der Hülse durch die Verbindungsfläche VF kann Gas eingeblasen werden, das am Gasstutzen GS angeschlossen wird. In Fig. 1, a surgical instrument T is shown for insertion of medical instruments inside the body of a patient, comprising a valve body V and a sleeve H, which enclose a passage channel DK. The passage channel DK of a closure flap VK can be closed gas-tight, which can be pivoted from a closed position into an open position when the instrument is inserted. Gas can be blown through the bores BV in the valve body and BH in the sleeve through the connecting surface VF, which gas is connected to the gas nozzle GS.
In Fig. 2 ist der Ventilkörper VK gegen die Hülse H verdreht, so daß die Einbohrungen BV und BK nicht deckungsgleich sind und damit weder Gas ein- noch ausströmen kann.In Fig. 2 the valve body VK is rotated against the sleeve H, so that the bores BV and BK are not congruent and thus neither gas can flow in nor out.
In Fig. 3 ist mindestens ein Stift S in dem Ventilkörper VK eingebracht, der in mindestens zwei Nuten N1 und N2 an der Hülse H eingreifen kann. Die Nuten sind so beabstandet, das bei Verdrehung die Einbohrungen BV und BH sich nicht mehr überschneiden.In Fig. 3 at least one pin S is inserted in the valve body VK, which can engage in at least two grooves N1 and N2 on the sleeve H. The grooves are spaced so that the bores BV and BH no longer overlap when twisted.
