摘要：
A device for positioning a reference element during aortic valve implantation surgery. The device includes a first extension member having a proximal end and a distal end, a connection member adapted to connect the first extension member to a support, and a coupling having a first end connected to the connection member and a second end connected to the proximal end of the first extension member so that the first extension member is moveable in multiple planes relative to the support. At least one reference datum is operatively connected to the distal end of the first extension member and extends in a straight line, the reference datum being moveable between a first position and a second position to enable precise locating of the reference datum during the aortic valve implantation surgery.
