Abstract: The invention relates to a rotation joint, especially for medical instruments, with a proximal and a distal part that are coupled to one another by means of a gear work and can be adjusted in relation to one another between a non-deflected starting position and an angled end position, where the gear work is housed in an intermediate part situated between the proximal and the distal parts and all three parts have at least one hollow center channel. In order to create a rotation joint that can be actuated by a non-angled position and can be secured in the deflected position, the invention proposes that the proximal part consists of two tubes that are arranged coaxially inside one another and can rotate in opposite directions around their longitudinal axis, where at least the outer tube is connected with a handle on its proximal side.

Abstract: The invention relates to a rotation joint, especially for medical instruments, with a proximal (1) and a distal part (2) that are coupled to one another by means of a gear work and can be adjusted in relation to one another between a non-deflected starting position and an angled end position, where the gear work is housed in an intermediate part (3) situated between the proximal (1) and the distal (2) parts and all three parts have at least one hollow center channel. In order to create a rotation joint that can be actuated by a non-angled position and can be secured in the deflected position, the invention proposes that the proximal part (1) consists of two tubes (4, 5) that are arranged coaxially inside one another and can rotate in opposite directions around their longitudinal axis, where at least the outer tube (5) is connected with a handle on its proximal side.
