1. A surgical instrument comprising:
(a) a body assembly comprising:
(i) a casing having a distal aperture formed in a distal end of the casing,
(ii) at least one resilient element housed within the casing proximally of the distal opening, and
(iii) a trigger; and
(b) an end effector assembly comprising:
(i) a proximal end configured to releasably couple to the body assembly,
(ii) a distal end having an end effector, wherein the end effector is configured to clamp tissue in response to actuation of the trigger, and
(iii) at least one shaft extending distally from the proximal end and including a proximal shaft portion configured to be inserted through the distal aperture, wherein the at least one shaft is operatively coupled with the end effector;
wherein the proximal shaft portion is configured to engage and deflect the at least one resilient element when the proximal shaft portion is inserted through the distal opening, and the at least one resilient element is configured to engage the proximal shaft portion to releasably couple the end effector assembly to the body assembly;
wherein the releasable coupling is configured to inhibit longitudinal translation between at least a portion of the end effector assembly and the body assembly while permitting rotation of the at least one shaft relative to the body assembly.
