Surgical instrument with mechanically operable lever

A surgical instrument (1) comprising:

• a handle (10) having a main body (20) with a central axis (C);
• a tubular body (40) having a main portion (41) extending from the handle and a distal end (44) remote from the handle (10);
• a distal tool (50), provided at the distal end (44) of the tubular body away from the handle;
• a lever (60) pivotably attached to the main body (20) and operable by a user's fingers for mechanically actuating the distal tool (50), the lever being pivotable relative to the main body (20) about a pivot axis (H) substantially normal to the central axis (C), the lever having a finger abutment section (70), wherein the finger abutment section comprises a lower finger rest (71a,71b), an upper finger rest (72a,72b) and a septum (73) fixed to the lower and upper finger rest and extending therebetween to form a separate first and second finger receiving portion for respectively receiving a first and a second finger of the user,
• wherein the lower finger rest is adapted for at least partially contacting the ventral sides of both the first and second finger during pivoting movement of said finger abutment section (70) towards the central axis (C), and wherein the upper finger rest is adapted for at least partially contacting the dorsal sides of both said fingers during pivoting movement of the finger abutment section (70) away from the central axis (C),
• wherein the septum (73) has a central plane (S), wherein a first abutment surface of the septum is arranged on a first side of said plane and adapted for abutting a lateral side of a portion of the first finger of the user's hand in the first finger receiving portion, and wherein a second abutment surface of the septum is arranged on an oppositely facing second side of said plane (S) and adapted for abutting a lateral side of a portion of the second finger of said hand at the same time,
• wherein the pivot axis (H) is fixed with respect to the main body (20) and wherein the lever is arranged for pivoting around the pivot axis (H) in such a manner that during pivoting of the lever the central plane of the septum (S) remains substantially coplanar with a plane parallel to the central axis (C),
• wherein the handle is provided with a user operable rotation control (30) that is rotatably connected to the main body and fixed to the tubular body in such a manner that rotation of the user operable rotation control relative to the main body causes a corresponding rotation of the tubular body,
• wherein the distal end (44) of the tubular body is adapted for bending relative to the main portion (41) of the tubular body, wherein the handle is provided with a user operable bending control (30) adapted for bending relative to the main body of the handle to mechanically cause bending of the distal tool relative to the distal end of the tubular body, and
• wherein the user operable rotation control and the user operable bending control together form a unitary user operable control (30) that is rotatable and bendable relative to the main body (20) of the handle.
