1. A surgical instrument comprising:
a handle having a first end, a second end, and a passage that extends from the first end to the second end through a portion of the handle having a maximum height measured in a direction of extension of the passage, wherein the maximum height of the handle is less than a length of the handle measured in a direction perpendicular to the direction of extension of the passage;
a shaft having a first end, a second end, a longitudinal axis extending from the first end to the second end, and a coaxial channel that extends completely through the shaft, wherein the shaft is connectable to the handle when the first end of the shaft is inserted from the second end of the handle into the passage to a position that is closer to the first end of the handle than to the second end of the handle, and wherein the handle comprises an actuator configured to be actuated in a direction parallel to an axis of extension of the length of the handle to release the connection between the handle and the shaft; and
a secondary instrument comprising an attachment portion that is attachable to the handle in a manner such that a combined maximum height of the handle and the attached secondary instrument remains less than the length of the handle;
wherein when the shaft and the handle are connected to one another, the secondary instrument is configured to be inserted from the first end of the shaft into the channel and to extend out of the second end of the shaft.
