DieErfindung betrifft eine chirurgische Pinzette mit einem zwei federndgegeneinander drückbareBranchen umfassenden Griffteil, von denen jede eine Pinzettenspitzeträgt. TheThe invention relates to a surgical forceps with a two-springpressed against each otherIndustries comprehensive grip part, each of which is a tweezer tipwearing.
ChirurgischePinzetten dieser Art werden bei medizinischen Operationen in vielfältiger Weiseeingesetzt, teils als reine Greifwerkzeuge, teils auch zum Koagulierenvon zwischen den Pinzettenspitzen angeordnetem Gewebe, in diesenFällenwerden die Pinzettenspitzen einpolig oder zweipolig mit einer elektrischenSpannungsquelle verbunden.surgicalTweezers of this type are used in medical operations in a variety of waysused, partly as pure gripping tools, partly also for coagulationfrom between the tweezer tips arranged tissue, in thismakeThe tweezer tips are single-pole or bipolar with an electricVoltage source connected.
Esist üblich,die Branchen der Pinzetten einstückigauszubilden, so dass insbesondere im medizinischen Bereich der Herstellungsaufwandrelativ hoch ist, insbesondere verhindert dies in vielen Fällen, chirurgischePinzetten als Wegwerfteile auszubilden.Itis common,the branches of tweezers in one pieceform, so that in particular in the medical field, the production costis relatively high, in particular, this prevents in many cases, surgicalTo form tweezers as disposable parts.
Esist Aufgabe der Erfindung, eine gattungsgemäße chirurgische Pinzette soauszubilden, dass der Herstellungsaufwand herabgesetzt werden kann.ItObject of the invention, a generic surgical tweezers soto train that the manufacturing cost can be reduced.
DieseAufgabe wird bei einer chirurgischen Pinzette der eingangs beschriebenenArt erfindungsgemäß dadurchgelöst,dass jede Pinzettenspitze Teil eines Aufsteckelementes ist, welchesAufsteckelement jeweils auf eine der beiden Branchen aufsteckbarund dadurch an dieser Branche festlegbar ist, und dass an den Aufsteckelementenund an den Branchen Ausrichtglieder vorgesehen sind, die die Aufsteckelementeund die Branchen beim Aufstecken der Aufsteckelemente auf die Branchenin eine definierte Lage relativ zu den Branchen lenken.TheseTask is in surgical tweezers described aboveType according to the invention therebysolved,that each tweezers tip is part of a slip-on, whichPlug-in element attachable to one of the two branchesand thus can be fixed to this industry, and that on the slip-on elementsand at the branches alignment members are provided, which are the Aufsteckelementeand the industries when attaching the slip-on elements to the branchesto steer in a defined position relative to the branches.
Aufdiese Weise sind die Branchen der chirurgischen Pinzette unterteiltin die eigentlichen Branchen, die Teil des Griffteiles sind, undin die Aufsteckelemente, die orientierungsrichtig auf die Branchen aufsteckbarsind. Es ist daher möglich,in einfacher Weise die Aufsteckelemente auszuwechseln, so dass dasselbeGriffteil wiederholt eingesetzt werden kann, auch wenn die Pinzettenspitzenfür jedenEinsatzfall neu gewähltwerden, wenn also die Aufsteckelemente als Wegwerfteile konzipiertsind.Onthis way, the branches of surgical tweezers are dividedinto the actual industries that are part of the grip, andin the slip-on elements, which can be attached correctly to the branchesare. It is therefore possiblein a simple way replace the Aufsteckelemente so that the sameHandle part can be used repeatedly, even if the tweezer tipsfor eachNew application selectedSo when the slip-on designed as disposable partsare.
DasAufstecken der Aufsteckelemente wird dabei erleichtert durch dieAusrichtglieder, die dafür sorgen,dass die Aufsteckelemente beim Aufstecken auf die Branchen in derrichtigen Orientierung zu den Branchen stehen und diese Orientierungim aufgesteckten Zustand auch beibehalten.ThePlugging the Aufsteckelemente is facilitated by theAlignment members who ensurethat the Aufsteckelemente when plugging on the branches in thecorrect orientation to the industries and this orientationalso maintained in the plugged state.
Esist besonders vorteilhaft, wenn zur Ausbildung einer Steckverbindungzwischen den Branchen und den Aufsteckelementen eines der beidenTeile eine Steckhülseund das andere einen in diese einschiebbaren, an deren Innenwandanliegenden Lagerzapfen aufweist. Auf diese Weise erhält man zwischender Steckhülseund dem Lagerzapfen eine sehr stabile Verbindung, die auch Biegemomentegut aufnehmen kann und die in einfachster Weise herzustellen ist.Itis particularly advantageous when the formation of a connectorbetween the branches and the slip-on elements of one of the twoParts a socketand the other one in this insertable, on the inner wallhaving adjacent journal. In this way you get betweenthe socketand the journal a very stable connection, which also has bending momentscan absorb well and is the simplest way to produce.
Esist weiterhin günstig,wenn Verriegelungsmittel vorgesehen sind, die das Aufsteckelementund die Branche gegen eine axiale Verschiebung sichern, wenn dasAufsteckelement auf die Branche aufgesteckt ist.Itis still cheap,when locking means are provided which the slip-onand secure the industry against axial displacement if thatPlug-on element is attached to the industry.
Insbesonderekönnendie Verriegelungsmittel einen Rastvorsprung und einen Rastrücksprung umfassen,die beim Aufstecken des Aufsteckelementes auf die Branche elastischmiteinander verrasten. Die Verriegelungsmittel werden also selbsttätig wirksam,wenn das Aufsteckelement auf die Branche aufgesteckt wird.Especiallycanthe locking means comprise a latching projection and a latching recess,the elastic when attaching the Aufsteckelementes on the industrylock together. The locking means are thus automatically effective,when the slip-on is attached to the industry.
Beieiner besonderen Ausführungsformist vorgesehen, dass die Steckhülseein Fenster aufweist, in das ein Rastvorsprung an dem Lagerzapfen eintaucht,wenn das Aufsteckelement auf die Branche aufgesteckt ist.ata particular embodimentis provided that the sockethas a window, in which a latching projection dips on the journal,when the slip-on is attached to the industry.
DieAufsteckhülsekann im Bereich des Fensters von einer Stabilisierungshülse umgeben sein,so dass die Aufsteckhülsetrotz des Fensters die notwendige Festigkeit beibehält.Theslip-onmay be surrounded by a stabilizing sleeve in the region of the window,so the slip-on sleevedespite the window maintains the necessary strength.
Esist vorteilhaft, wenn der Lagerzapfen im Bereich des Rastvorsprungeseine diametrale Durchbrechung aufweist und dadurch in zwei elastischgegeneinander biegbare, nebeneinander liegende Arme unterteilt ist.Die Arme könnenelastisch gegeneinander gebogen werden, wenn das Aufsteckelementaufgeschoben wird, und dabei werden die Rastvorsprünge an denArmen so weit radial nach innen geschoben, dass die Steckhülse über diesegleiten kann, bis die Rastvorsprüngeelastisch ausfedern und in das Fenster der Aufsteckhülse einrasten.Itis advantageous if the bearing pin in the region of the locking projectionhas a diametrical opening and thereby in two elasticmutually bendable, adjacent arms is divided.The arms canbe elastically bent against each other when the slip-onis pushed, and thereby the locking projections on thePoorly pushed radially inward so far that the receptacle over thiscan slide until the latching projectionselastically spring down and engage in the window of the slip-on sleeve.
Beieiner bevorzugten Ausführungsformist vorgesehen, dass die Ausrichtglieder von den Branchen und denAufsteckelementen vorstehende Orientierungszungen sind, die jeweilseine Führungsfläche aufweisen,und dass die Führungsflächen beim Aufsteckendes Aufsteckelementes auf die Branche aneinander anliegen und dadurchdas Aufsteckelement relativ zur Branche in die gewünschte definierte Lagelenken.ata preferred embodimentis provided that the alignment members of the branches and theAufsteckelementen projecting orientation tongues are, respectivelyhave a guide surface,and that the guide surfaces when pluggingthe Aufsteckelementes rest on the industry together and therebythe slip-on element relative to the industry in the desired defined positionto steer.
Günstig istes, wenn mindestens eine der Orientierungszungen federnd ausgebildetist, so dass die Führungsflächen elastischgegeneinander gedrücktwerden.Cheap isif at least one of the orientation tongues is resilientis, making the guide surfaces elasticpressed against each otherbecome.
Beieiner Steckverbindung, die eine Steckhülse und einen Lagerzapfen umfasst,könnensich die Orientierungszungen vorzugsweise im Innern der Steckhülse befinden,wenn das Aufsteckelement auf die Branche aufgesteckt ist.For a connector that has a plug sleeve and a journal, the Orientierungszungen can preferably be located inside the receptacle when the plug-on is attached to the industry.
Dadurchwerden die Orientierungszungen im Inneren der Steckhülse gegenjede Verformung oder Beschädigunggeschützt.TherebyThe orientation tongues are in the interior of the receptacle againstany deformation or damageprotected.
Eineder beiden Orientierungszungen kann eine Verlängerung des Lagerzapfens sein.AThe two orientation tongues can be an extension of the bearing journal.
Esist vorteilhaft, wenn die Führungsflächen relativzur Aufsteckrichtung der Aufsteckelemente geneigt sind, so dassdurch diese Neigung die Führungsflächen beimfortschreitenden Aufstecken mit einer zunehmenden Federkraft gegeneinandergedrücktwerden, außerdemermöglichtdiese Neigung eine Orientierung der beiden Teile zueinander beim Aufstecken.Itis advantageous if the guide surfaces relativeare inclined to Aufsteckrichtung the slip-on, so thatby this inclination the guide surfacesprogressive plugging with an increasing spring force against each otherdepressedbe, as wellallowsthis tendency an orientation of the two parts to each other when plugging.
Gemäß einerbevorzugten Ausführungsform derErfindung wird die Pinzettenspitze als Keramikbauteil ausgebildetmit mindestens einem elektrisch isolierenden Bereich aus einem Keramikmaterialund mit mindestens einem Bereich aus einem elektrisch leitfähigen Keramikmaterial,welches durch Einbettung elektrisch leitfähiger Partikel seine elektrische Leitfähigkeiterhält.Auf diese Weise bestehen sowohl die elektrisch leitfähigen Bereicheals auch die elektrisch isolierenden Bereiche der Pinzettenspitzeeinheitlich aus Keramikmaterial, d.h. sie haben ähnliche mechanische und chemischeEigenschaften, beispielsweise eine sehr hohe Druckfestigkeit, eine hoheResistenz gegenüberChemikalien oder eine geringe Anhaftung an anliegendem Gewebe.According to onepreferred embodiment ofInvention, the tweezer tip is formed as a ceramic componentwith at least one electrically insulating region of a ceramic materialand at least one region made of an electrically conductive ceramic material,which by embedding electrically conductive particles its electrical conductivityreceives.In this way, there are both the electrically conductive areasas well as the electrically insulating regions of the tweezer tipuniformly made of ceramic material, i. they have similar mechanical and chemicalProperties, for example, a very high compressive strength, a highResistance toChemicals or low adhesion to adjacent tissue.
DieSchwierigkeiten, die bei herkömmlichen Pinzettenspitzendurch das Aufeinandertreffen sehr unterschiedlicher Materialienin den elektrisch leitenden und in den elektrisch nicht leitendenBereichen auftreten, könnendurch die Kombination eines elektrisch isolierenden Keramikmaterialsund eines elektrisch leitfähigenKeramikmaterials überwundenwerden.TheDifficulties with conventional tweezer tipsthrough the meeting of very different materialsin the electrically conductive and in the electrically non-conductiveAreas can occurby the combination of an electrically insulating ceramic materialand an electrically conductiveCeramic material overcomebecome.
Besondersvorteilhaft ist es, wenn die elektrisch isolierenden und die elektrischleitfähigenBereiche monolithische Sinterkörperausbilden. In diesem Falle ist die Pinzettenspitze als einheitlicherKörperaus Keramikmaterial anzusehen, der lediglich durch Zusätze bereichsweiseelektrische Leitfähigkeiterhält,die übrigenEigenschaften sind überdas gesamte Volumen des Werkzeuges aufgrund der einheitlichen keramischenNatur des Werkstoffes ähnlichoder weitgehend identisch, die Gefahr einer Trennung im Grenzbereichzwischen elektrisch leitfähigenund elektrisch isolierenden Bereichen besteht nicht.EspeciallyIt is advantageous if the electrically insulating and the electricconductiveAreas of monolithic sintered bodiesform. In this case, the tweezer tip is as uniformbodyTo look at ceramic material, the only area by additiveselectric conductivityreceivesthe remainingProperties are overthe entire volume of the tool due to the uniform ceramicNature of the material similaror largely identical, the risk of separation in the border areabetween electrically conductiveand electrically insulating areas does not exist.
Dasverwendete Keramikmaterial kann beispielsweise Al2O3 sein, und es ist günstig, wenn das elektrischleitfähigeKeramikmaterial als leitfähige PartikelTiN enthält,gegebenenfalls könntenauch Kohlefädenin das Keramikmaterial eingebettet sein.The ceramic material used may, for example, be Al2 O3 , and it is favorable if the electrically conductive ceramic material contains TiN as conductive particles, if appropriate also carbon filaments could be embedded in the ceramic material.
Esist günstig,wenn der Anteil der elektrisch leitfähigen Partikel in dem elektrischleitfähigenKeramikmaterial zwischen 30 und 70 Volumenprozent liegt. Durch denAnteil der leitfähigenPartikel kann der elektrische Widerstand auf die gewünschte Größe eingestelltwerden, wesentlich ist lediglich, dass die elektrisch leitfähigen Partikelhomogen in dem nicht leitfähigenKeramikmaterial verteilt sind, so dass elektrische Brücken zwischenden elektrisch leitfähigenPartikeln entstehen, die die elektrische Leitfähigkeit verursachen.Itis cheap,when the proportion of electrically conductive particles in the electricconductiveCeramic material is between 30 and 70 percent by volume. By theProportion of conductiveParticles can set the electrical resistance to the desired sizeIt is only essential that the electrically conductive particleshomogeneous in the non-conductiveCeramic material are distributed so that electrical bridges betweenthe electrically conductiveParticles form, which cause the electrical conductivity.
DieGröße der nichtleitenden Keramikpartikel und der leitfähigen Partikel in dem elektrischleitfähigenKeramikmaterial kann zwischen 1 und 100 μm liegen, vorzugsweise zwischen3 und 50 μm.Zwischen nicht leitenden Keramikpartikeln und den elektrisch leitfähigen Partikelnkönnenin dem elektrisch leitfähigenKeramikmaterial Leerstellen angeordnet sein, deren Größe liegtvorzugsweise zwischen 0,1 und 10 μm,insbesondere zwischen 0,5 und 5 μm.TheSize of notconductive ceramic particles and the conductive particles in the electricallyconductiveCeramic material can be between 1 and 100 microns, preferably between3 and 50 μm.Between non-conductive ceramic particles and the electrically conductive particlescanin the electrically conductiveCeramic material may be located voids whose size ispreferably between 0.1 and 10 μm,in particular between 0.5 and 5 microns.
DieErfindung betrifft auch eine Haltevorrichtung für mindestens ein Aufsteckelementder chirurgischen Pinzette, wie es vorstehend beschrieben ist.TheThe invention also relates to a holding device for at least one plug-on elementsurgical tweezers as described above.
Einesolche Haltevorrichtung soll den Benutzer in die Lage versetzen,in besonders einfacher Weise die chirurgische Pinzette mit dem Aufsteckelementzu verbinden, das bei manchen chirurgischen Pinzetten unter Umständen sehrklein ausgebildet und daher schwierig zu handhaben ist.Asuch holding device should enable the user toin a particularly simple manner, the surgical forceps with the slip-onThis may be very common in some surgical forcepsSmall and therefore difficult to handle.
DieseAufgabe wird bei einer Haltevorrichtung der vorstehend beschriebenenArt erfindungsgemäß dadurchgelöst,dass das Aufsteckelement in Längsrichtungherausziehbar in einer Aufnahme der Haltevorrichtung gehalten ist.Auf diese Weise kann man durch Annähern der Haltevorrichtung miteinem in die Haltevorrichtung eingesetzten Aufsteckelement an dasGriffelement die Branche einerseits und das Aufsteckelement andererseitsso gegeneinander führen,dass das Aufsteckelement auf die Branche aufgesteckt wird, bis eineaxiale Festlegung durch die Verriegelungselemente erfolgt. Anschließend kann mandie Haltevorrichtung einfach zum freien Ende des Aufsteckelementeshin abziehen, da das Aufsteckelement an der Branche durch die Verriegelungsmittelgehalten wird.TheseTask is in a holding device of the aboveType according to the invention therebysolved,that the slip-on element in the longitudinal directionpulled out in a receptacle of the holding device is held.In this way you can by approaching the fixture withan inserted into the holding device Aufsteckelement to theHandle element the industry on the one hand and the plug-in element on the otherso against each other,that the slip-on is attached to the industry until aaxial fixing is done by the locking elements. Then you canthe holding device simply to the free end of the slip-onpull off, since the attachment element to the industry by the locking meansis held.
Besondersvorteilhaft ist es, wenn an der Haltevorrichtung nebeneinander zweiAufsteckelemente in einem Abstand, der dem Abstand der unverformtenBranchen des Griffteils der Pinzette entspricht, in Längsrichtungherausziehbar gehalten sind. Es ist daher mit einer solchen Haltevorrichtung möglich, beideAufsteckelemente gleichzeitig durch Heranführen der Haltevorrichtung andas Griffelement auf die Branchen aufzuschieben und nach dem vollständigen Aufsteckenin Längsrichtungaus der Haltevorrichtung herauszuziehen.It is particularly advantageous if on the holding device side by side two Aufsteckelemente at a distance corresponding to the distance of the undeformed branches of the handle part of the tweezers speaks, are pulled out in the longitudinal direction. It is therefore possible with such a holding device, both slip-on elements at the same time postpone by bringing the holding device to the handle element on the industries and pull out after the complete plugging in the longitudinal direction of the holding device.
DieHaltevorrichtung kann ein Halterohr aufweisen, in welchem die Aufsteckelementeim Reibschluss festgelegt sind, so dass die Aufsteckelemente indem Bereich, in dem sie in der Haltevorrichtung gehalten sind, gutgeschütztsind.TheHolding device may have a holding tube, in which the Aufsteckelementeare fixed in frictional engagement, so that the Aufsteckelemente inthe area in which they are held in the holding device, wellprotectedare.
DasHalterohr kann in die Aufnahme der Haltevorrichtung einsetzbar sein,insbesondere kann die Aufnahme einen seitlichen Längsschlitzaufweisen, der zum Einsetzen des Halterohres elastisch aufweitbarist. Die Haltevorrichtung kann damit in einfachster Weise wiedermit neuen Aufsteckelementen bestückt werden,die in einem Halterohr im Reibschluss gehalten sind.TheHolding tube can be used in the recording of the holding device,In particular, the receptacle may have a lateral longitudinal slothave, for the insertion of the holding tube elastically expandableis. The holding device can thus again in the simplest waybe equipped with new slip-on elements,which are held in a retaining tube in frictional engagement.
