Problems solved by technology

Although the welded seam has only a small diameter, the welded seam also has only a short length (expansion in the direction of heat flow), which limits the role of the welded seam as a heat barrier

Embodiment Construction

[0027] for example, figure 1 The instrument 10 shown in is shown as a tubular shaft instrument for open surgery and / or laparoscopic surgery. The instrument 10 comprises a shaft 11 at the distal end of which an implement 12 is arranged. A housing 13 is used to grasp the instrument 10 , the housing 13 includes a handle 14 and is connected to the proximal end of the shaft 11 . However, the instrument 10 can also be embodied as a flexible endoscopic instrument, wherein the instrument 12 and the shaft 11 are correspondingly small and fine, and the shaft 11 is bendable. The following basic descriptions also apply to such embodiments.

[0028] figure 2 The appliance 12 is shown with two branches 15 , 16 which cooperate in a pliers-like manner and which in principle have the same basic design. Therefore, yes in Figures 3 to 6 The following descriptions of the branch 16 shown in FIG. 2 also apply correspondingly to the branch 15 .

Abstract

A branch of an instrument comprising a metal part, which is embodied in one piece seamlessly, which comprises the electrode support as well as the electrode plate and connection webs. Preferably, this metal part is produced in an additive production method, for example selective laser melting (SLM). The branches are suitable for instruments for open surgery as well as for laparoscopic and flexible endoscopic instruments.

Description

field of invention [0001] The present invention relates to a surgical instrument for the electrosurgical monopolar or bipolar application of electrical current flowing into biological tissue, and in particular to a sealing instrument. Background of the invention [0002] Devices for the coagulation of biological tissue between two branches of the device are known from the prior art, the device comprising at least one movable branch. To this end, EP2554132 shows an instrument, each branch of which comprises an electrode support and a sheet-shaped electrode. The electrode support can consist of a one-piece metal part, or of a plastic-coated metal part. The electrodes are connected to the electrode support by a plurality of spot weld joints. On the one hand, this results in a reliable mechanical connection and, on the other hand, only low heat transfer between the electrode and the electrode support. Although the welded seam has only a small diameter, the welded seam also ha...
