Microsurgical holding and/or cutting instrument

A surgical handheld instrument comprising:

• a first lever element and a second lever element hinged to the first lever element by a lever element hinge, each lever element including a grip portion on a first side of the lever element hinge and a jaw portion on a second side of the lever element hinge,
• a first leaf spring and a second leaf spring which are proximally connected to each of the grip portions as a first spring portion and a second spring portion, respectively, the first spring portion and the second spring portion extending each of the grip portions, the first leaf spring and the second leaf spring each having a proximal free end, the proximal free end of the first leaf spring being coupled to the proximal free end of the second leaf spring by a hinged joint, the hinged joint including a hinge pin at the proximal free end of the first leaf spring and at least one bearing eye at the proximal free end of the second leaf spring,
• wherein the at least one bearing eye comprises an eye-hole having a longitudinal axis extending therethrough, wherein the at least one bearing eye also comprises a continuous longitudinal slit extending diagonally through the at least one bearing eye relative to the longitudinal axis of the eye-hole,
• wherein, when the first lever element and the second lever element are hinged together by the lever element hinge, the hinge pin can only be radially inserted into the at least one bearing eye once a longitudinal axis of the hinge pin and the slit are caused to become aligned from a misaligned orientation by twisting at least one spring portion.
