Coagulationa instrument

The invention relates to a coagulation instrument in the form of tweezers with one of the pinsette legs, which are isolated from one another as coagulation electrodes, under voltage setting connection to a high frequency voltage generating Generator for the coagulation of an item held between the tips of the tweezer arms *

Such instruments are already known per se, it is disadvantageous that verhältni3mäßig complicated terminal structure of Pinzetteninstrumentas aur conjunction with a generator * This derartiga Inatrumente be unwieldy, relatively difficult to operate and its storage or at rest "their sterilization eating difficult - through such relatively expensive constructions such known instruments are also relatively expensive,

there is therefore the task of creating a coagulation instrument in the form of tweezers for tying off flawed blood vessels to create which avoids these disadvantages, thereby

ought to be able to store and sterilize the instrument well and easily. At the same time, a good, less disruptive connection with a generator producing the high-frequency voltage should be possible »

To solve this problem, the invention proposes a coagulation instrument in the form of tweezers, which is mainly

indicates that the coagulation forceps can be supplied with the high frequency via a plug connection Tweezers separated from this connection in a very simple manner can be stored and sterilized. At the same time, the instrument itself can be made very handy and simple

It is useful; .venn the electrical connection of the coagulation forceps with the high-frequency generator is formed by a plug connection _B in which the rear end of the forceps directly forms a detachable plug link of this plug connection. Additional contact pins or protrusions on the linden of the instrument are thereby avoided in a simple and advantageous manner. Such a construction is particularly simple, since each instrument uses almost unchanged tweezers

According to a particular development of the invention, the instrument is attached to its accommodation when not in use a holding 'device with a tiltable, the contact plug approximately corresponding Klemmhül83 for receiving the instrument end, with ler underside of this clamping sleeve each • in the direction of the instrument tor questioning can PEP ₉ extended ^ö tützarm provided _P dor at its free end an upwardly directed Aakröpfung forming with a fork recess for the legs of the forceps closed cohesive detecting owns "This is a good and easy storage and SteriLisicrui? .g of the instrument _c which is preferably is formed blank, it is possible can be affected without any electrical devices. This measure is therefore given its own inventive importance. Above all, however, this measure is advantageous in combination with the plug connection according to the invention, since this design of the instrument for connection to the high-frequency generator via a plug connector also enables it to be advantageously accommodated in such a holding device. Due to the extended support arm with its fork-shaped recess, a particularly plate-separating lower
