DE2639157A1 - HF surgery electrode - is made of flat spring metal stamping fitting into adaptor for electrode holder - Google Patents

Abstract

The electrode (1) for high frequency surgery can be made as a flat stamping of springy metal. It can be shaped with two spade ends (2, 3) joined by a thin strip (4), one spade end (2) being the active part. This can be inserted into a resilient gripping member (6) for insertion into an electrode holder (5) without rotation. In one design the electrode can be a strip with pointed ends, and either end can be inserted into the gripping member (6). In another design (fig. 3) the thin strip between two spade ends can be bent into a circle, so that the ends can be inserted into the gripper. The circular part then forms the active part. A further design has a spade portion with an active part in the form of a bent wire attached to it.

Description

High frequency surgical device

The invention relates to a high-frequency surgical device with a one-piece Electrode, which consists of an active part and an insertable part in an electrode holder and therefrom removable electrode shaft.

Such electrodes are used in high-frequency surgery for separation or coagulation of biological tissue is used. The active part is as a Needle, plate, wire loop, tape loop, ball or knife-like blade. The active part can be connected to an electrode shaft or directly to the electrode shaft be connected, which is used to attach the electrode in the electrode holder. In known electrodes of this type, the active part or the electrode stem is soldered to the electrode shaft.

There are also known electrodes in which the active part and the Electrode shaft can be produced by cutting or non-cutting shaping. The production of such electrodes is therefore relatively cumbersome and expensive. Furthermore, it can happen in known high-frequency surgical devices that the electrode by an assistant in a position opposite to the correct one twisted position is used, or that the electrode through during use Exercise s # rk0 # r ## ####% from the right work situation turned is, whereby the handling of the high-frequency surgical device is difficult.

It is therefore the object of the invention to provide a high-frequency surgical device to improve the type mentioned in such a way that easier to manufacture electrodes can be held more reliably in a predetermined work situation. These The object is achieved according to the invention by the subject matter of claim 1. Advantageous further developments of the invention are the subject matter of the subclaims.

Such an electrode holder makes that easier and cheaper to manufacture electrodes can be used, in particular from a Electrodes punched out from spring plate so that soldering work is not required. That's why it is Also, it is not necessary for the user to repeat these electrodes for so long: used until they are due to the cleaning and particularly necessary in surgery Sterilization become unusable because electrodes can be manufactured in such a cost-saving manner if desired, can be thrown away after a single use. Also results the formation of a flat electrode shaft in conjunction with a resilient one Gap element has the advantage that the electrode only has to be in the correct working position can be used and is held in this position, which is what conventional electrodes is not guaranteed with a round electrode shaft.

The invention is to be explained in more detail, for example, with the aid of the drawing will. 1 shows an exploded view of an electrode holder and an electrode according to a first embodiment of the invention; Fig. 2 1 to 4 modified exemplary embodiments of electrodes according to the invention; and Fig. 5 shows an embodiment of an adapter - with the help of which electrodes according to of the invention can be used in an electrode holder for round electrode shafts can.

The exemplary embodiment of a high-frequency surgical device shown in FIG. 1 according to the invention shows an electrode 1 made of sheet metal and a flat electrode shaft 3, an angled electrode shaft 4 and a active part 2 in one-piece design ~ * lwt .. Ce isr-like electrode can also on photochemical ways can be produced inexpensively in different designs.

As with known high-frequency surgical devices of this type, a Electrode holder 5 is provided with a mouthpiece 5a with a circular cross-section be, in which a plug-in tube 9 is inserted, in which an electrode is more common Art can be inserted with a round electrode shaft. When the mouthpiece 5a at the end of the cylindrical interior of the electrode holder 5 has a non-circular cross section has, an adapter in the form of an insertion part can be inserted into the insertion tube 9 10 (Fig. 5) can be used with a shaft with a circular cross-section, of the / rf # ik "r section protrudes with a non-circular outer circumference 11 may, for example, have a hexagonal cross-section, so that it is in a hexagonal mouthpiece 5a inserted on the electrode holder 5 so that it cannot rotate can be. A resilient gap element can be inserted into the central opening 12 in the pipe section 11 6 can be used, which is used to hold the flat electrode shaft in a way that prevents it from twisting 3 (Fig. 1 -4) is used.

According to the embodiment shown in FIG. 1, however, instead of the plug-in tube 9, the resilient gap element 6 in the interior of the Electrode holder 5 can be used twist-proof. In Fig. 1 there are two different ones Embodiments for a resilient gap element 6 are shown. The embodiment 7 is a rolled leaf spring and embodiment 8 is a folded leaf spring. The torsion-proof arrangement can, for example, have a non-circular cross-section the gap elements and corresponding design of the inner wall of the electrode holder 5 succeed.

The exemplary embodiment of an electrode 1 shown in FIG. 2 shows a knife-shaped electrode for separating biological tissues.

It only consists of a flat sheet metal, which is expediently a spring plate and is designed so that the flat electrode shaft 3 and the active Part 2 have the same outline, so that one or the other end of the strip-shaped Electrode 1 can be inserted into the gap element 6.

The embodiment of an electrode 1 shown in FIG. 3 has likewise a strip-shaped formation with two serving as electrode shaft 3 Ends so that this electrode forms a tape loop with an active loop part 2 for cutting out biological tissue can be bent. This electrode can expediently be and is stored in the flat state only before the operation, slightly bent by hand into a loop and inserted into the springy loop The gap element 6 is inserted into the electrode holder 5.

The embodiment shown in Fig. 4 shows one of a A piece of wire bent electrode 1 with, for example, a ring-shaped part 2, the one over an electrode stem 4 with a serving as a flat electrode shaft 3 rectangular wire loop is connected, making this electrode readily can be bent from a single piece of wire.
