Provided is a medical device implantation apparatus, comprising: an outer sheath (4), connected to a first portion of a handle (6) and extending from a proximal end to a distal end; a middle sheath (3), the middle sheath (3) being arranged in the outer sheath (4), and the middle sheath (3) being connected to a second portion of the handle (6); an inner sheath (2), the inner sheath (2) being allowed to pass through the middle sheath (3), the inner sheath (2) being connected to a third portion of the handle (6), and the inner sheath (2) being movable relative to the outer sheath (4); outer casings (1), with at least two outer casings being provided, and a distal end of the inner sheath (2) being respectively fixedly connected to the outer casings (1); and a medical device, arranged around the inner sheath (2) and partially accommodated in the outer casings (1). The medical device can be released by manipulating the third portion of the handle (6). When the medical device is released, the first portion of the handle (6) is withdrawn towards the proximal end, and the medical device is partially released from the outer sheath (4); the third portion of the handle (6) is then pushed towards the distal end, the medical device is separated from the outer casings (1); and finally, the first portion of the handle (6) is withdrawn, and the medical device is released and implanted.
