Surgical jaw part tool, surgical instrument, and robotic surgical instrument system

Abstract

The present invention provides a bipolar surgical jaw part tool (8) and a bipolar surgical instrument (50) created therewith. The jaw part tool (8) has two, pivotally mounted arms (2, 2′), which have an electrically conductive material, and a force transmission means (9), which is operatively connected to the arms (2, 2′) and is designed to provide the instrument (50) by coupling to an instrument shaft (51) and to an actuating means (52), wherein the arms (2, 2′) are arranged on the distal side of the instrument shaft (51), and the force transmission means (9) is arranged in the instrument shaft (51) so as to be movable along a longitudinal axis (L) and capable of being brought into engagement with the actuating means (52) on the proximal side of the instrument shaft (51). The jaw part tool (8) has a jaw part core (1) made of an electrically insulating material and two recesses (10, 10′) separated from one another by a core wall (1′), each providing a joint axis (A, A′) which divides the recesses (10, 10′) into an exit and an actuation pivot region (13, 14). Each arm (2, 2′) has a mounting portion (23) between a jaw part portion and an actuating portion (21, 22), on which mounting portion the arm (2, 2′) is mounted in the recess (10, 10′) so as to be pivotable around the respective joint axis (A, A′), wherein the jaw part portion (21) extends through the exit pivot region (13) and out of the recess (10, 10′), and the actuating portion (22) is arranged in the actuation pivot region (14) of the recess (10, 10′). The jaw part tool (8) has two control tabs (3, 3′), which are connected to the force transmission means (9) and each extend into the actuation pivot region (14) of the recesses (10, 10′) and there engage with the actuating portion (22) of the respective arm (2, 2′). Furthermore, a robotic surgical instrument system is disclosed.
