One medicine is fixed, such as a robotic suturing device (100), is used to fix a cardiac implant equipment (400A, 400B) with a fixing component (102), such as a suture. The fixed device of medicine includes an elongated sheath (101), extends in a longitudinal direction and has (101A) of proximal end and end (101B) of distal end. There is a support portion (101C) to support elongated sheath to cardiac implant equipment and/or to tissue (20) for the distal end of elongated sheath. The fixed device of medicine also includes that a fixing component guides equipment (103) from sheath (101) and end (103B) of (103A) with proximal end and distal end. The distal end (103B) of fixing component guidance equipment (103) is configured to conveying fixing component (102) to cardiac implant equipment and fixed cardiac implant equipment, to the ring (20) of the valve with fixing component (102).
