SURGICAL INSTRUMENT WITH MECHANICALLY OPERABLE LEVER

A surgical instrument includes a handle with a main body having a central axis, a lever pivotable around a pivot axis fixed with respect to the main body. The lever includes a finger abutment section including a lower finger rest contacting the ventral sides of a user's first and second fingers during pivoting movement of the finger abutment section towards the central axis, and an upper finger rest contacting the dorsal sides of both the fingers during pivoting movement of the finger abutment section away from the central axis; and a septum fixed to lower and upper finger rests and extending therebetween forming a separate first and second finger receiving portion for respectively receiving a first and a second fingers. The lever pivots around the pivot axis such that during pivoting of the lever, the septum central plane remains substantially coplanar with a plane parallel to the central axis.
