Title: SURGICAL INSTRUMENT OF TWO-BRANCH DESIGN WITH IMPROVED CLEANING SUITABILITY
Abstract:
The invention relates to a scissors-type or pliers-type medical instrument (1) with a first instrument branch (2), a second instrument branch (3) and a bearing element (6) coupling the instrument branches (2, 3) in a contact screw joint, wherein the two instrument branches (2, 3) can be pivoted relative to each other and mutually contact each other in a joint section (4, 5) in a working pivot region by means of contact surfaces (13, 14, 15) that face each other, so that in the working pivot region the instrument branches (2, 3) rest against each other with their respective contact surfaces (13, 14, 15) in a bearing and guiding manner, and the instrument branches (2, 3) can be positioned in a cleaning position outside the working pivot region, wherein the bearing element (6) is preferably threadless and on an end section is directly securely fixed to the first instrument branch (2) and on another end section has a head (8), which conically widens either continuously or in steps as the distance from the first instrument branch (2) increases, which head extends through a through-opening (10) in the second instrument branch (3), which through-opening has a continuous or stepped conical form, wherein the through-opening (10) is designed in the form of a slot (10), wherein the bearing element (6) can be rotationally positioned in the slot (10) and is received therein in a translationally fixed manner, more particularly is received in a fixed position in the longitudinal direction (L) of the slot (10).
