Abstract

A surgical instrument (1) and an end effector (3) for a surgical instrument (1), the end effector (3) comprising a first leg (4) and a second leg (5) configured to pivot in different directions to and from a plane (PL). The first leg (4) is configured to pivot around a first pivot axis (PA1), the second leg (5) is configured to pivot around the first pivot axis (PA1) or a second pivot axis (PA2) parallel with the first pivot axis (PA1). The surgical instrument (1) comprises a hollow shaft (2) and an actuating arrangement (6) extending within the hollow shaft (2) and generating the pivoting movement of the first leg (4) and/or the second leg (5). The hollow shaft (2) may comprise an electrically conductive material core layer (2a) and a peripheral layer (2b) comprising at least one of a section of anodized conductive material and/or an anodized coating applied onto the conductive material. The first leg (4) may have a first tissue engagement surface (4a) comprising a plurality of first serrations (13), and the second leg (5) may have a second tissue engagement surface (5a) configured to compress tissue together with the first tissue engagement surface (4a) of the first leg (4). The serrations may have a non-linear extent.
