AI Technical Summary
Technical Problem
Existing surgical jaw tools require a through guide pin for assembly, which complicates the assembly process and may lead to protruding joint components.
Method used
A surgical jaw tool design featuring a fork-shaped support with guide tracks and pivot pins, eliminating the need for a through guide pin, and utilizing positive-locking, material-locking, and friction-locking connections for assembly, ensuring secure joint operation without protrusions.
Benefits of technology
The design allows for easy assembly and secure operation of the jaw tool without through guide pins, maintaining functionality and preventing joint components from protruding beyond the outer surface, while ensuring the jaw sections remain aligned and securely connected.

Abstract
The present invention relates to a surgical forceps tool (1), a surgical instrument (10), a forceps tool (1) and a method for the production thereof. The surgical forceps tool (1) has two jaw parts (2, 2'), an actuation element (3), which defines a longitudinal axis (L), and a fork holder (4) having two arm portions (50) and at least one tube portion (60) through which the actuation element (3) extends for engagement with the two jaw parts (2, 2'), which are mounted between the two arm portions (50) so as to be movable about a pivot axis (S) in each case. Each jaw part (2, 2') has, on an actuation portion (20), a pivot pin (21) which is received in a pivot recess (52), formed on the arm portion (50), in order to form the pivot axis (S), and has a coupling opening (22) in which one of two drive pins (32, 32') formed on a distal end portion (30) of the actuation element (3) is received. Each jaw part (2, 2') has a guide pin (23) and each arm portion (50) has a guide track (53), concentric with respect to the pivot recess (52), for guiding the guide pin (23), the distance of which from the pivot pin (21) corresponds to a distance of the guide track (53) from the pivot recess (52). The fork holder (4) is formed in a joining arrangement, wherein each fork arm (5) has a joining portion (51), and the fork body (6) has two contact portions (61, 61') which are connected to the joining portions (51) of the fork arms (5) in the joining arrangement.
