The present application discloses a stabilizer for operations on the heart, preferably on the beating heart, with a fastening shaft (10) and a tissue contact component (20) with two substantially parallel, elongate bearing elements (21, 21) which are provided on a base section (22) and are adapted to be arranged on two opposite sides of a blood vessel (B), such that at least one portion of the blood vessel (B) extends between the two bearing elements (21, 21), wherein the base section (22) of the tissue contact component (20) is mounted on one end (11) of the fastening shaft (10). At least one bearing element (21) has a slit (23) which extends in the longitudinal direction of the bearing element (21) at least over a portion thereof, and the fastening shaft (10) has an axially extending channel (14) which extends at least over a portion of the fastening shaft (10) and, in the area of that end (11) of the fastening shaft (10) on which the base section (22) is mounted, is in communication with at least one connection channel (15) that connects the axially extending channel (14) to the environment, wherein the axial end (11) of the fastening shaft (10) is preferably closed. A suction device (30) is preferably provided on the stabilizer, which suction device (30) can be mounted releasably on the fastening shaft (10), in particular by being pushed onto the fastening shaft (10) from the direction of the free end (12) thereof. The suction device (30) has a connection component (31), with the aid of which the suction device (30) can be fastened releasably on the stabilizer and which has at least one connection cavity (33), and at least one suction component (34) which has an axially extending channel that is connected to the at least one connection cavity (33) and that is adapted to be arranged at least partially in a slit (23) of a bearing element (21) when the suction device (30) is mounted on the stabilizer. |
