Abstract
A manually operable HF instrument in bipolar construction includes a jaw part having two electrode legs which can be moved relative to each other like pincers or scissors, and an instrument handle for operating and activating the jaw part. A separate electrode mount is articulated on at least one electrode leg of the jaw part so as to be able to pivot relative to it, an electrode in turn being elastically/pliably installed on the electrode mount.
Claims13
A medical HF instrument in bipolar construction comprising:
- two electrode carriers which can be moved toward each other, each electrode carrier provided with at least one longitudinally extending sealing-/welding electrode or electrode array, each longitudinally extending sealing-/welding electrode or electrode array comprising shanks that extend in a longitudinal direction of the electrode carriers, the shanks forming a longitudinal gap,
- at least one of the at least one longitudinally extending sealing-/welding electrode or electrode array being supported on a separate electrode mount by an elastic support between the electrode or electrode array and the electrode mount, and
- the electrode mount being supported on one of the electrode carriers by an articulating support between the electrode mount and the electrode carrier so that the electrode mount is rotatable, pivotable or tiltingly supported relative to said one of the electrode carriers.
A medical HF instrument in bipolar construction comprising:
- two electrode carriers which can be moved toward each other, each electrode carrier provided with at least one longitudinally extending sealing-/welding electrode or electrode array,
- at least one of the at least one longitudinally extending sealing-/welding electrode or electrode array being installed on a separate electrode mount that is supported on one of the electrode carriers in a rotatable, pivotable or tilting fashion, in such a manner that said at least one longitudinally extending sealing-/welding electrode or electrode array is pliably supported on the separate electrode mount, and
- one or more spring elements inserted between the separate electrode mount and the electrode/electrode array installed thereon, said one or more spring elements keeping the electrode/electrode array spaced from the separate electrode mount toward the opposing electrode/electrode array,
- wherein the one or more spring elements are inserted in accommodation pockets formed in the separate electrode mount.
