1. An instrument comprising:
a handle comprising a distal end comprising a distal thumb wheel and a proximal end comprising a proximal thumb wheel;
a first instrument part that is removably connectable to a first implant part of a distal end of an implant via actuation of the proximal thumb wheel; and
a second instrument part that is removably connectable to a second implant part of a proximal end of the implant via actuation of the distal thumb wheel;
wherein, when the first instrument part is connected to the first implant part, the second instrument part is connected to the second implant part, and the instrument is actuated, the first instrument part and the first implant part translate relative to the second instrument part and the second implant part along a central longitudinal axis of the instrument without rotating about the central longitudinal axis during instrument actuation.
