The application discloses a cardiac surgery stabilizer, preferably under heart beat, comprising a fixed shaft (10) and a tissue contacting part (20) with two generally parallel elongated support members (21, 21), Since the support member is provided on the base portion (22) and is arranged on two opposite sides of one blood vessel (B), at least a part of the blood vessel (B) has two supports. Passing between the members (21, 21), the base portion (22) of the tissue contacting component (20) is attached to the end (11) of the fixed shaft (10). At least one support member (21) has a slot (23) extending over at least a portion of the support member in the longitudinal direction of the support member (21), and a duct through which the stationary shaft (10) passes in the axial direction. (14), which duct extends at least over a portion of the fixed shaft (10) and is at least in the region of the end (11) of the fixed shaft (10) to which the base portion (22) is attached. A connecting duct (15) leads to this connecting duct, which connects the axially passing duct (14) with the periphery, and the axial end (11) of the fixed shaft (10) is preferably closed. It has been. Preferably, the stabilizer is provided with a suction device (30), which can be removably attached to the fixed shaft (10), in particular by sliding on the fixed shaft (10) from the free end (12) of the fixed shaft. Yes. The suction device (30) includes a connection component (31) that allows the suction device (30) to be removably fixed to the stabilizer and includes at least one connection cavity (33), and at least one suction component (34). This suction component has an axially passing duct connected to at least one connecting cavity (33) and at least when the suction device (30) is attached to a stabilizer. Partly arranged in the slot (23) of the support member (21).本出願は、固定シャフト（１０）と、ほぼ平行な細長い２つの支持部材（２１、２１）付き組織接触部品（２０）とを備える、好ましくは心拍動下での心臓手術用スタビライザーを開示し、支持部材が、ベース部分（２２）に設けられているとともに、１つの血管（Ｂ）の対向する２つの側に配置されるよう
