Embodiment Construction

[0037] In the following description, the same reference numerals are used for the same parts or for parts having the same role.

[0038] FIG. 1 shows an endoscopic surgical instrument 10 according to a first preferred embodiment with a working device 11 in a state of use. The working device 11 is designed here as a probe for argon plasma coagulation (APC). The probe 11 has been guided by means of the endoscope 80 to the tissue 100 to be treated, which in this case is in the area of ​​the patient's vocal cords. The probe 11 includes a first working channel 14 for argon plasma coagulation and a second working channel 15 arranged coaxially with the first working channel 14 . At the end of each channel 14 and 15 is an outlet 14a or 15a respectively. An electrode 50 is provided in the first working channel 14 to supply a high-frequency current to the tip 12 of the probe 11 and thus to the tissue to be treated 100, the electrode 50 is connected to a high-frequency circuit for gene...

Abstract

The invention relates to an endoscopic-surgery apparatus for argon-plasma coagulation (APC) to treat biological tissue. The surgery apparatus comprises a tube, a tubular probe or similar working device that can be inserted into an endoscope, with a first channel such that by way of the first channel, as a first working means, there can be guided to the tissue an electrode connected to an HF generator in order to generate a high-frequency current, as well as argon or a similar inert gas. This endoscopic-surgery apparatus is further developed in order to simplify endoscopic interventions employing argon-plasma coagulation, while simultaneously increasing the efficiency of a treatment. To this end, the working device comprises at least one second channel through which at least one second working means is guided to the tissue.

Description

technical field [0001] The invention relates to an endoscopic surgical instrument for argon plasma coagulation (APC) according to the preamble of claim 1 . Background technique [0002] High frequency surgery using techniques including argon plasma coagulation has been used in human and veterinary medicine for many years to coagulate and / or resect biological tissue. During this procedure, suitable electrosurgical instruments are used to pass a high-frequency current through the tissue to be treated so that the tissue is altered by coagulation of proteins and dehydration. The blood vessel is thus closed by the coagulation process and the bleeding is stopped. Then, a cutting process following the coagulation process enables the already coagulated tissue to be completely severed. [0003] The argon plasma coagulation method coagulates tissue in a non-contact manner and achieves effective hemostasis and tissue inactivation. In this coagulation, an inert working gas, such as a...
