Embodiment Construction

[0038] In the following, the same reference signs are used for identical and similar active parts, superscripts being occasionally used for differentiation.

[0039] figure 1 A perspective view of an HF surgical instrument is shown. The surgical instrument comprises two arms 20 connected to each other by an articulated connection 22 in the form of forceps or scissors, so that two clamping members 2 provided at the distal ends of the arms 20 can be moved from an open position to a closed position ,vice versa. Furthermore, at the proximal ends of the arms are provided two actuating means 24 in this case in the form of handles, which enable opening and closing of the arms 20 and thus also of the clamping member 2 .

[0040] The clamping elements 2 together form a grasping region 4 for tissue to be coagulated or to be treated similarly to HF surgery (see Figure 5 ) can be gripped in this gripping area 4 . For HF surgery, an electrode 6 is provided at the clamping part 2, in p...

Abstract

The present invention relates to a bipolar clamp for HF surgery, particularly for coagulating tissue, having at least two bipolar clamping parts (2) displaceable relative to each other defining a span range (4) between an open position and a coagulation position, and comprising electrodes (6) for coagulating tissue held by the clamping parts (2) in the span range (4), wherein the clamping parts (2) are made substantially completely of an electrically conductive core encompassed by an electrically insulative thin layer (8), wherein the electrodes (6) are disposed as thin pin electrodes on the clamping parts (2), and penetrate the electrically insulative thin layer (8), extending into the span range (4).

Description

technical field [0001] The present invention relates to a bipolar forceps for HF surgery, in particular for coagulating tissue, which bipolar forceps has at least two bipolar clamping parts which can be opened relative to each other position and a coagulation position to define a grasping zone, and the bipolar clamp has electrodes for coagulating tissue grasped by the clamping member in the grasping zone. Background technique [0002] High frequency surgery has been used for many years in human and veterinary medicine to coagulate and / or ablate biological tissue. With the aid of appropriate electrosurgical instruments, high-frequency currents are passed through the tissue to be treated so that said tissue begins to change by coagulation of proteins and dehydration. The tissue constricts to seal off the blood vessels and stop bleeding. The current intensity may then be increased, which causes tissue fluid to boil off and cell membranes to rupture, allowing complete separati...
