Catheter device having a catheter and an actuation device

摘要

The invention relates to a catheter device, having a catheter (1), an actuation device (8) at a first end of the catheter and also a mechanical transmission element (9, 10) for transmitting a movement along the catheter to the actuation device, the actuation device having a coupling element (14) which is connected to the transmission element (9, 10) and can be actuated by the latter relative to the longitudinal direction of the catheter in a first degree of freedom, and also a conversion element (15) which can be actuated by the coupling element and which converts the actuation movement at least partially into a movement in a second degree of freedom. As a result, a combined movement at the distal end of the catheter can be produced particularly simply for compression and release of a functional element.

主权项

1. A catheter device, having a catheter, an actuation device at a first end of the catheter, a drive element and also a mechanical transmission element for transmitting a movement along the catheter to the actuation device, the actuation device having a coupling element which is connected to the transmission element configured to be actuated by the transmission element relative to a longitudinal direction of the catheter, and also a conversion element configured to be actuated by the coupling element, said conversion element has screw-like tracks configured to convert an axial movement at least partially into a rotary movement relative to said longitudinal direction.
