The invention provides techniques for securing a manipulating device that holds a moving organ, such as a beating heart. The manipulating device may be held securely and yet accommodate the natural rotational motion of the organ. In an exemplary application of the invention, a manipulating device holds the heart by the apex. The manipulating device is coupled to a support shaft, which is coupled to a key. The key is shaped so that it can engage a socket of a keyway in a securing structure. When the key engages the socket, the securing structure supports the key, which in turn supports the support shaft, the manipulating device and the heart. The rotational freedom of the heart is accommodated by, for example, allowing the support shaft to twist or by allowing the key to rotate in the socket.
L'invention porte sur des techniques de fixation d'un dispositif manipulateur pouvant saisir un organe en mouvement tel qu'un coeur en train de battre et le maintenir fermement tout en en suivant le mouvement naturel de rotation. Dans l'une des applications le dispositif manipulateur, qui saisit le coeur par son sommet, est solidaire d'un arbre support sur lequel est mont~e une clavette dont la forme est appari~e ~ celle d'une ouverture m~nag~e dans une structure porteuse. Lorsque la clavette est engag~e dans ladite ouverture, ladite structure retient la clavette qui ~ son tour retient l'arbre support, ainsi que le dispositif manipulateur et le coeur qui y sont fix~s. La libert~ de rotation du coeur peut par exemple provenir de la torsion de l'arbre ou de la rotation de la clavette dans l'ouverture.
