Abstract
A current supply arrangement (22) is used for electrical supply of two electrodes (18, 19), as well as for mechanical force transmission in a thermofusion instrument. Due to the configuration of the two electrical conductors (23, 28) as upright arranged flat parts and the force concerned coupling thereof in an interlocking section (32), the electrical conductors (23, 28) can be used as mechanical stiffening elements, whereby a filigree, gap-free, easily and reliably sterilizable configuration is achieved. The current supply of the instrument (10) is provided via one single cable (20) only, which is provided only on one of the two jaws (11, 12).
Claims15
A medical thermofusion instrument (10) comprising:
- a first jaw (11) and a second jaw (12) that are pivotably supported with respect to one another at a hinge (13) that defines a hinge axis (14);
- a current supply arrangement (22) arranged in the first jaw (11) and comprising a first conductor (23) and a second conductor (28), wherein the first conductor (23) is electrically connected with a first electrode (18) provided on the first jaw (11) and the second conductor (28) is electrically connected with a second electrode (19) provided on the second jaw (12);
- wherein the first and second conductors (23, 28) are formed by flat strip-shaped elements (24, 29);
- and
- the current supply arrangement (22) comprises a first section (A1) in which portions (25) of the first and second conductors (23, 28) are arranged in a common plane (E1) and adjacent to one another at a joint (30) filled with a rigid electrically insulating material (31).
