Embodiment Construction

[0040] figure 1 An electrosurgical instrument 10 is shown by which an end-to-end anastomosis can be performed between two hollow organ or vessel parts 12 (see FIG. 2 ). Instrument 10 includes an elongated body 14 on which two tools 16 (16A and 16B) are disposed. Each of tools 16 has a two-piece construction. Each tool part has an extension 18 connected to the main body 14 and extending perpendicular to the longitudinal extension of the main body 14 . At the distal end of the extension 18, there are arranged respective cylindrical half-shells 20 perpendicular to said extension and parallel to the main body 14, respectively. The extensions 18 are pivoted on the main body 14 so that, on the one hand, each pair of extensions 18 can be rotated about the longitudinal axis of the main body 14 and the extensions 18 can also be rotated relative to each other in order to bring the half-shells 20 into the open position and closed Location. The half-shells 20 are symmetrically formed ...

Abstract

The invention relates to an electrosurgical instrument (10) for producing an end-to-end anastomosis between two hollow organ sections (12), comprising two tools (16) that can be moved in relation to each other, each of the tools having a high-frequency electrode (24), by means of which the hollow organ sections (12) can be fused to each other. According to the invention, the two tools (16) are substantially sleeve-shaped or at least can be brought into a sleeve shape such that a first tool (16A) can surround a first hollow organ section (12A) and a second tool (16B) can surround a second hollow organ section (12B). The electrodes (24) are each formed on an end face (22) of the sleeve-shaped tools (16), around which end face the respective hollow organ section (12) can be everted, and the two tools (16) can be moved in relation to each other in such a way that the electrodes (24) can be aligned and can clamp the everted hollow organ sections (12A, 12B) between the electrodes.

Description

technical field [0001] The invention relates to an electrosurgical instrument for performing an end-to-end anastomosis between two hollow organ parts or blood vessel parts according to the preamble of claim 1 and to an electrosurgical instrument according to the preamble of claim 11 The corresponding method described in the section. Background technique [0002] For reconnecting two hollow organ parts, for example two intestinal parts, at their open ends after a surgical intervention, ie for performing an end-to-end anastomosis, different instruments and methods are used. End-to-end anastomoses can be performed with sutures, clip suturing instruments (especially circular staplers), or TFT (tissue fusion technique) instruments. Especially in the case of intestinal anastomosis, circular staplers are routinely used. In the case of an anastomosis in the region of the large intestine, the instrument is inserted transanally in order to provide the instrument inside the intestina...
