Embodiment Construction

[0043] The drawings are only schematic in nature and are used exclusively for the understanding of the present invention. Identical elements have the same reference numerals and can be interchanged with each other.

[0044] Figure 1a The surgical instrument 1 of the branched design according to the invention is shown in an assembled and closed / non-operating state (configured position). The female instrument part or the first instrument part 2 is coupled / hinged to the male instrument part or the second instrument part 5 via the coupling / hinge area 3 so that these parts can pivot relative to each other. The coupling area 3 is formed on a part of the first instrument part 2 via a hollow volume (hollow volume through-box) 4 and on a part of the second instrument part 5 via a guide section (through-section) 6 . This is preferably a feed-through / box connection, eg known from DE 20 2011 000800 U1, so that reference can be made at this time to the disclosure therein.

Abstract

The invention relates to a surgical instrument (1) comprising: a female instrument part (2) defining a hollow volume (4) in a coupling zone (3); a male instrument part (5), The male instrument part forms in the coupling zone (3) a guide section (6) intended to pass at least partially through the hollow volume (4); and a pivot element (7 ), said pivoting element has an upper section (8), a central section (9) and a lower section (10) and couples said female instrument part (2) and said male instrument part (5) to each other to such that the female instrument part and the male instrument part can pivot relative to each other about the axis of rotation of the pivot element (7), wherein a transverse upper contact step (12) is formed on the pivot element (7) Between said upper section (8) and said central section (9), and a transverse lower contact step (13) is formed between said lower section (10) of said pivot element (7) and said between the central sections (9).

Description

technical field [0001] The present invention relates to a surgical instrument according to the general term of claim 1 comprising two instrument parts which can be pivoted relative to each other. Surgical instruments of the type according to the invention may for example be clamps, gripping means, cutting means and / or holding means, in particular scissors, grasping forceps and similar branches, mainly used in surgery and with any geometry instrument. [0002] Background of the Invention [0003] Surgical instruments of the instrument branch type are used in almost all medical fields, which ensure relative movement (similar to scissors) of two instrument parts hinged to each other. In order to allow the instrument parts to rotate in a planar manner, the instrument parts have contact surfaces that slide under friction as they rotate relative to each other, thus preventing skewing of the instrument parts. Since the two instrument parts are usually made of the same material, th...
