A lever arm is to be arranged between the handle and the pressure lever, wherein the lever arm has the second jaw part and pressure can be applied to the lever arm by the pressure lever. ## Claims ### Claim 1 A surgical forceps (1) comprising at least one handle part (2) and a pressure lever (3) which is mounted pivotably relative to the handle part, and further comprising a jaw consisting of two jaw parts (7.1, 7.2), wherein one of the jaw parts (7.1) is provided on the handle part (2) and wherein a lever arm (4) which has the second jaw part (7.2) and is pressurized by the pressure lever (3) is arranged between the handle part (2) and the pressure lever (3) and the lever arm (4) is mounted pivotably in relation to the handle part (2), wherein a rolling body (5) is arranged between the pressure lever (3) and the lever arm (4) and a force exerted on the pressure lever (3) is transmitted via the rolling body (5) to the lever arm (4), the rolling body (5) is guided in a slotted guide (9), the slotted guide (9) for guiding the rolling body (5) is provided in the handle part (2) and/or in a housing cover (8) and the lever arm (4) has a concave receptacle (20) for the rolling body (5) with an internal radius which is larger than an external radius of the rolling body (5) in the region of the rolling surfaces, wherein, by exerting a force on the pressure lever (3), the latter pivots about a fulcrum/pivot point (13.2) and exerts a force on the rolling body (5) which is guided in the slotted guide (9) in the direction of the lever arm (4), as a result of which the lever arm (4) begins to pivot about a fulcrum/pivot point (13.1) and the jaw part (7.2) of the lever arm (4) moves in the direction of the jaw part (7.1) of the handle part (2), and the mounting between handle part (2) and pressure lever (3) and between the handle part (2) and the lever arm (4) is a free mounting. ### Claim 2 (depends on 1) The forceps (1) as claimed in claim 1, wherein a fulcrum/pivot point (13.1) of the lever arm (4) is located on a side facing away from the jaw part (7.2). ### Claim 3 (depends on 1) The forceps (1) as claimed in claim 1, wherein a fulcrum/pivot point (13.2) of the pressure lever (3) is located on a side of the pressure lever (3) which faces the jaw parts (7.1, 7.2). ### Claim 4 (depends on 1) The forceps (1) as claimed in claim 1, wherein the handle part (2) is at least partially a part of a housing. ### Claim 5 (depends on 1) The forceps (1) as claimed in claim 1, wherein the handle part (2) has, at a jaw-side end, a concave receptacle (11.2) for the pressure lever (3). ### Claim 6 (depends on 1) The forceps (1) as claimed in claim 1, wherein the handle part (2) has, at an end facing away from the jaw, a concave receptacle (11.1) for the lever arm (4). ### Claim 7 (depends on 1) The forceps (1) as claimed in claim 1, wherein the handle part (2) has, at the jaw-side end, a recess which is suitable for receiving the lever arm (4). ### Claim 8 (depends on 7) The forceps (1) as claimed in claim 7, wherein the recess for receiving the lever arm (4) is designed as a closed channel (10) in the direction of a longitudinal axis (L) of the handle part (2). ### Claim 9 (depends on 1) The forceps (1) as claimed in claim 1, wherein the handle part (2) has a hook-in recess (12) which is suitable for receiving a spring (6). ### Claim 10 (depends on 1) The forceps (1) as claimed in claim 1, wherein the housing cover (8) is suitable for closing the housing. ### Claim 11 (depends on 1) The forceps (1) as claimed in claim 1, wherein the jaw parts (7.1, 7.2) are aligned substantially parallel to each other. ### Claim 12 (depends on 1) The forceps (1) as claimed in claim 1, wherein the jaw parts (7.1, 7.2) are suitable for receiving tool elements (16.1, 16.2) which are exchangeable. ### Claim 13 (depends on 12) The forceps (1) as claimed in claim 12, wherein at least one of the tool elements (16.1, 16.2) for cutting implants has receiving pins (18.1, 18.2) for receiving and securing the implant (15). ### Claim 14 (depends on 13) The forceps (1) as claimed in claim 13, wherein the tool elements (16.1, 16.2) for cutting implants (15) have spring pressers (17.1, 17.2). ### Claim 15 (depends on 14) The forceps (1) as claimed in claim 14, wherein the spring pressers (17.1, 17.2) are secured in the tool elements (16.1, 16.2) for cutting implants (15) by means of screws in the tool elements (16.1, 16.2), which screws secure the tool elements (16.1, 16.2) in the handle part (2) and/or lever arm (4).
