plurality of surgical instruments is configured to include at least one mechanical mating mechanism for mating with the reusable handle assembly. ### Claim 11 (depends on 10) The surgical system according to claim 10, wherein the at least one mechanical mating mechanism of the at least one surgical instrument of the plurality of surgical instruments includes a plurality of spaced protrusions and a plurality of spaced recesses for enabling snapping or coupling with the reusable handle assembly. ### Claim 12 (depends on 9) The surgical system according to claim 9, wherein the end effector assembly includes a pair of opposed jaw members such that at least one of the jaw members is induced to move relative to the other jaw member between open and closed positions in response to manipulation of the reusable handle assembly. ### Claim 13 (depends on 1) The surgical system according to claim 1, wherein the reusable handle assembly includes at least sensor positioned thereabout. ### Claim 14 (depends on 1) The surgical system according to claim 1, wherein the reusable handle assembly includes at least one indicator configured to indicate at least one parameter related to the reusable cannula assembly and the plurality of surgical instruments. ### Claim 15 (depends on 14) The surgical system according to claim 14, wherein the at least one indicator is selected from a group
