Embodiment Construction

[0042] The drawings are merely schematic in nature and are intended exclusively for the understanding of the invention. Identical elements have the same reference signs and can be interchanged with each other.

[0043] Figure 1a The surgical instrument 1 according to the bifurcated design of the invention is shown in assembled and closed / non-operating state (constructed position). The female or first instrument part 2 is coupled / hinged to the male or second instrument part 5 via a coupling / hinge area 3 so that these parts can pivot relative to each other. The coupling region 3 is formed via a hollow volume (hollow volume feedthrough) 4 on part of the first instrument part 2 and via a guide section (feedthrough) 6 on part of the second instrument part 5 . This is preferably a feed-through / box connection, known for example from DE 20 2011 000800 U1, so that reference can be made to the disclosure therein at this time.

Abstract

The invention relates to a surgical instrument (1), comprising: a female instrument part (2), which defines a hollow volume (4) in a coupling region (3); a male instrument part (5), which forms a guide section (6) in the coupling region (3), which guide section is prepared for at least partially passing through the hollow volume (4); and a pivoting element (7), which has an upper section (8), a center section (9), and a lower section (10) and which couples the female instrument part (2) and the male instrument part (5) to each other in such a way that the female instrument part and the male instrument part can be pivoted relative to each other about an axis of rotation of the pivoting element (7), wherein a lateral upper contact step (12) is formed between the upper section (8) and the center section (9) of the pivoting element (7) and a lateral lower contact step (13) is formed between the lower section (10) and the center section (9) of the pivoting element (7).

Description

technical field [0001] The invention relates to a surgical instrument according to the generic term of claim 1 comprising two instrument parts which can be swiveled relative to each other. Surgical instruments of the type according to the invention may for example be grippers, gripping devices, cutting devices and / or holding devices of any geometry, in particular scissors, grasping forceps and similar branches, mainly used in surgery instrument. Background of the invention [0002] Surgical instruments of the instrument branch type are used in almost all medical fields, which ensure a relative movement (like scissors) of two instrument parts articulated to each other. In order to allow the instrument parts to swivel in a planar manner, the instrument parts have contact surfaces that slide under friction as they swivel relative to each other, thus preventing skewing of the instrument parts. Since these two instrument parts are usually made of the same material, there is a r...
