SURGICAL INSTRUMENT HAVING TERMINAL REGION THROUGH WHICH FLOW CAN OCCUR

摘要

The invention relates to a branch-crossed surgical instrument (1) having a female branch (2) and a male branch (4), each having a terminal portion (6, 8) over the longitudinal extension thereof and the terminal portion (6) of the female branch (2) is passed through by a passage opening (10), which has a distal and a proximal longitudinal end surface (12a, b), each having two outer edges (14a - d) and is adjusted to receive the terminal portion (8) of the male branch (4), such that the two terminal portions (6, 8) form a plug-through closure in an assembly position of the instrument (1), characterized in that the passage opening (10) has a length, wherein the outer edges (14a - d) of the longitudinal end surfaces (12a, b) are exposed in all relative positions of the two branches (2, 4), in particular in a completely closed position and/or in a completely opened position of the instrument (1), and not covered by the male branch (4).
