摘要：
A surgical instrument implementing a leaflet grabbing mechanism by a leaflet grabbing structure is provided, in which the leaflet can be grabbed and clamped between a first and a second abutment surface. The first, proximally facing abutment surface in this belongs to a swivel-out portion of the leaflet grabbing structure. More in particular, swivel-out portion comprises at least a first arm (111) and a second arm (112). In a released state, when the leaflet grabbing structure is released from a catheter, the arms are capable of swiveling: the first arm is capable of swiveling out with respect to a main body (101) to which it is attached, and the second arm is capable of swiveling relative to the first arm so that in a leaflet grabbing position the first abutment surface faces proximally. The second arm comprises a recess arranged so that a chord extending between a released distal implant part and a proximal implant part can extend therethrough and be released by a lateral relative movement. The second abutment surface may be constituted by a press pad formed by a distal end face of the counterportion (80) that is releasable from the catheter and axially movable relative to the main body.L'invention concerne un instrument chirurgical mettant en œuvre un mécanisme de préhension de feuillet à l'aide d'une structure de préhension de feuillet, dans lequel le feuillet peut être saisi et pincé entre des première et seconde surfaces d'appui. La première surface d'appui orientée de manière proximale fait partie d'une section de pivotement de la structure de préhension du feuillet. La section de pivotement comprend, plus précisément, au moins un premier bras (111) et un second bras (112). À l'état libéré, lorsque la structure de préhension de feuillet est libérée d'un cathéter, les bras sont capables de pivoter : le premier bras est capable de pivoter par rapport à un corps principal (101) auquel il est fixé, et le second bras est capable de pivoter par rapport au premier b
