Medical instrument with a contoured axle pin
First Claim
1. A medical instrument comprisinga distal end area,jaw parts arranged at said distal end area which are movable relative to one another, andan axle pin,said jaw parts being pivotable about a circular section of said axle pin,said axle pin being received in an opening at said distal end area,wherein said axle pin comprises a head which is non-circular, and a contour of said opening corresponds to a contour of said head, said non-circular head in said opening secures said axle pin against rotation,wherein said axle pin is made up of at least two components which can be joined to one another,wherein said at least two components comprise a bushing and a bolt which can be inserted into said bushing,wherein said at least two components which can be joined to one another composing said axle pin both have a non-circular head,wherein said heads of said axle pin are respectively configured as a polygon;
- wherein the corners of said polygon are rounded, andwherein said distal end area of said medical instrument is designed as a fork head in whose opposite outer faces recessed openings are formed, into which said non-circular heads of said at least two components can be received in a way that said whole axle pin with said bushing and said bolt is received with an exact fit and flush in said fork head.
