Forceps for medical purposes, in particular for sclerosing or overcooking tissue.

The invention relates to forceps for medical purposes, in particular for sclerosing or boiling tissue, with a forceps outer tube, a forceps inner tube and thereby actuatable forceps jaw parts in which a Heat source is arranged.

Such pliers are already known in which the heat source is formed by an electrical heat probe, which is arranged in the fixed tong Haulteil. The heat probe is detachably connected to the pliers,

so that the pliers can be used either with or without the heating element * (DT-GH 7 344 297).

It is also known to use high-frequency electrodes for sclerosing the tissue, in which the electrical Electricity must flow through the patient's body can lead to unwanted burns. But also when using the electrical heating elements mentioned as a wall probe there is the disadvantage that due to the high conductivity of moist media at least electrical Leakage currents flow into the body cavity, which cause damage in the vicinity of the tissue to be cooked can. In addition, these known pliers are technically comparatively complex.

Finally, there is also a device on endoscopes known with a light source arranged at the outer end of a light guide, in which the light source arranged separately from the endoscope and with this over a light guide known per se and flexible in the area outside the endoscope is connected (DT-PS 1 113 788). In this way, large and powerful light sources can be used for both the investigation as well as for cinematography or television without impairing the handiness of the Endoscope or the treatment of the patient suffers.

The invention is based on the object of using a heat source in the case of forceps of the type mentioned at the outset, through which the risk of causing iron damage in the body cavity is completely eliminated.

This object is achieved by the invention in that a light emitter is arranged at the proximal end of the stage.

The word "light rays" should also include heat ripples be connected, it is a matter of particular around infr ^ ot rays, which, although still in the visible range but are preferably used to give off heat. The person skilled in the art knows which light frequencies a show particularly intense heat emission.

Another embodiment of the invention provides for an infrared reflector radiator to be found on the proximal end of the forceps is arranged and that the forceps have a transparent rod for forwarding the rays to the jaw parts having·

transparent rod has the advantage of little effort. As the well-known infrared reflector heater also only a relatively small effort condition, the pliers according to the invention has the further advantage that they are comparatively not very much overall is expensive.

It is advantageous that the transparent rod in the pliers inner tube is arranged. The transparent rod is expediently troughed in the stationary one Out of the jaw part of the forceps, which results in a very simple construction.

It is also very particularly preferred that the transparent rod in the area of the forceps jaw parts with one of the rays reflective surface is provided. In this way, the light or heat rays can be in a very specific way Direction are directed in which they are then much more intense than without such a reflective Area.

Further advantages and details of the invention emerge from the following description of a Exemplary embodiment with reference to the single figure of the drawing, which shows a pair of pliers in side view represents.

In the drawing you can see the pliers with the two handles 1o and 11, the handle 1o with the Pliers inner tube 5 is attached, while the handle 11 via an articulated connection 6 with the pliers outer tube 4 communicates. By moving the handle 11 relative to the handle 1o, the outer tube of the pliers 4 opposite the inner forceps tube 5 in the direction of the distal end with the two jaw parts 1 and 2 moved, whereby the articulated jaw part 1 a forceps movement compared to the stationary jaw part 2 executes. As far as described so far, such pliers are known and therefore do not need to be explained in more detail.

Glemäe of the invention is at the proximal enae of the forceps Infrared reflector reflector 8 with a halogen bulb

arranged, its radiation on d ^ n further to the left Visible transparent rod 7 is concentrated, through which the radiation is directed to the mouse parts 1 and 2 will. The transparent rod 7 is thus arranged in the pliers inner tube 5 and can be up to the end of the stationary troughed jaw part 2 out.

At this distal end of the transparent rod is a reflective surface 3 arranged through which the Radiation is deflected to the tissue gripped by the jaws. This area can be in the rod 7 itself be formed, or it can also be a special surface be provided from a reflective material. As a rule, the angle of this reflective surface is chosen so that the radiation is deflected upwards approximately perpendicular to the longitudinal direction of the rod 7 in the figure.

The infrared reflector radiator 8 is easily exchangeable together with a housing Io at the proximal end attached. The distance between the radiator and dea

proximal end of the transparent rod 7 is preferably chosen so that its point-like collected light beam meets this rod end 7.

The invention can also be used for pliers with a flexible shaft are used, in which case a flexible light guide known per se is used instead of the rod 7 can find, which can also be arranged separately from the pliers, whereby the handiness is improved. This second embodiment, not shown, can therefore preferably also be used in the embodiment shown. In addition, the rod can be preferred be made of quartz.

For use, the radiator 8 is connected to the plug 12 connected to a conductive cable. In order to be able to easily dose the heat radiation, a not shown kttfft Transformer must be switched on in the electrical line leading to plug 1.2.
