Abstract: A bipolar tubular shaft instrument (1) has instrument legs (3) and (4), for the operation of which a pull- and/or push rod (6) is axially displaceable within a tube (7). These two parts are insulated relative to one another and are connected to current terminals (11) and (12). For electrically connecting the push rod, a plug pin (15) is provided which is displaceable relative to an opposing contact (14) and engaged therewith. The plug pin (15) is arranged on the push rod (6) neighboring the connecting joint (9) with the actuating handle (10) in generally in a direction of orientation and movement. Thus the contact remains in existence in spite of the movement, and is present in each case upon the instrument legs being closed.

Abstract: A coagulation clamp (1) has clamp jaws (4) and two projections (2b or 2c, 2d) that impinge on these jaws directly or indirectly and that can be pivoted relative to one another on a common joint (2) with the aid of hand grips (3). The projections are insulated in the area of the joint and each connected directly or indirectly with a high-frequency terminal (HF). Here, the joint openings (6) are coated with an insulation that surrounds the joint axle (7) in the position of use, this insulation usefully being formed by a respective insulating sleeve (8). The joint axle (7) is made up of a sleeve (71) and an insert (72) that can be placed therein in telescoping fashion and that has a press-fit seating and that, on the side of sleeve (71) facing away from the insertion side, extends up to or into an opening (9a) of a termination (9) of this sleeve (71) and is fixedly connected with this sleeve termination (9), preferably being welded thereto. This results in a stable joint (2) that can absorb large forces.

Abstract: A connecting plug (1) for a bipolar coagulation instrument having an insulating body (3) for mechanically combining and electrically separating and insulating both of its blades (2) or electrical connecting lugs is provided. The blades (2) have holes (7) in the interior of the insulating body (3) at a point at which the insulating body (3) itself has holes (6), the holes (6) in the insulating body (3) and the holes (7) in the blades (2) lying superimposed in each case so that anchoring elements (8) can in each case jointly penetrate these holes (6, 7) and can thus immobilize the blades (2) against shifting in their openings (5) in insulating body (3). In this way, a mechanical securing of the blades is obtained. Both holes (6) in the insulating body (3) can be blind holes and end at a distance from each other, which combines good positive mechanical immobilization of the blades (2) with an improved insulating effect.

Abstract: A coagulation instrument has a handle section and detachably connected thereto an electrode shank (4). Electrode conductors (5, 6) are led in the electrode shank from contact pick-off points (7, 8) situated in the direction of the handle to the operating end (9) of the electrode shank. In the region of the contact pick-off points staggered in the longitudinal direction of the electrode shank (4), directly adjacent to the respective internal conductors (5, 6), there is in each case an opening (15) in the insulating outer cover (11). In this region contact sleeves (13, 14) are arranged on the electrode shank and have a depression (16) penetrating the respective opening (15) for contacting the corresponding conductor (5) or (6).

Abstract: A bipolar coagulation forceps 1 with a connection 2 for high frequency energy and two forceps limbs 4 capable of being pressed together against a spring tension is so constructed that a rinsing tube can be provided in a simple manner and without impinging on the space between the forceps limbs 4. For this purpose, the forceps limbs 4 comprise grips 5 which can be pushed together against spring tension with working limbs 6 subsequently fastened on them, whereby then at least one of the working limbs 6 has a hollow cross section or is constructed as a tube and has a connection 7 for the rinsing fluid, so that guidance parts 11 can be arranged between the grips 5 for the reciprocal guidance of the working tips 3 of the forceps 1. The working limbs 6 are for this reason arranged on parallel narrow sides 8 of the grips 5, that is lateral to the grip areas, where the guiding parts 11 are accommodated.

Abstract: A bipolar medical coagulation and/or cauterizing instrument has two elongated electrodes with first end portions which constitute the working end of the instrument and second end portions which are connectable to different poles of a high-frequency generator. The intermediate portions of the electrodes are surrounded by deformable insulators which are shrunk onto the respective electrodes and are confined in a tubular member serving to prevent the electrodes from moving relative to each other. To this end, the intermediate portions have cross sections which are out-of-round and/or which vary in the longitudinal direction of the respective electrodes. The insulators closely follow the outlines of the respective intermediate portions, and the tubular member closely follows the outlines of the insulators.

Abstract: A bipolar coagulation forceps wherein the switch at the inner side of one of its legs can be closed by an actuator at the inner side of the other leg. The switch and the actuator have cooperating centering and guide elements which engage one another to prevent any shifting of the jaws at the working ends of the legs during that stage of pivoting of the legs when the jaws already engage each other but the pivoting of the legs relative to each other must continue in order to close the switch. The latter is connected with a terminal at the rear ends of the legs by a conductor which is confined in a tube at the inner side of the leg carrying the switch. The outer side of the leg which carries the actuator has a finger-receiving flute which enhances the flexibility of the respective leg and renders it possible to pivot the legs relative to each other subsequent to engagement of the jaws with one another.

Abstract: The legs of a forceps constitute two coagulation electrodes each of which has a jaw at one end and a terminal at the other end. The two terminals are electrically insulated from each other and constitute a projection having a spherical or frustoconical portion which can be inserted into a socket at the front end of a pistol-shaped coupling device serving to connect the electrodes with a source of high-frequency energy when the forceps is to be used as a coagulation instrument. The terminals of the legs can be moved into mere abutment with the terminals of conductors which are embedded in the insulating carrier of the coupling device.

Abstract: A forceps has legs which are connected to each other at the first of their nds and are movable toward and away from each other with their second ends in response to the application of pressure against their intermediate portions to thereby flex the legs in the region of the first ends. One of the legs carries a pin which extends into and is guided by a tubular component on the other leg so as to ensure that the legs are held against stray movements during each and every stage of their movement between open and closed positions. The tubular component cooperates with the one leg to determine the closed positions, and such component cooperates with the pin to determine the open positions, of the legs. The pin and the tubular component are disposed within the confines of and between the intermediate portions of the two legs in a region which is remote from the second ends and close to those parts of the intermediate portions which serve as handgrip means.
