The disposable body includes a first disposable member, a second disposable member including first and second wall portions, and a third disposable member. The first wall portion defines a first aperture therethrough and a first cavity configured to receive therein a first portion of the switch assembly. The third disposable member includes a third wall portion, wherein a body of the second disposable member and the third wall portion define an opening configured to allow a shaft of a hemostat-style surgical instrument to pass therethrough. The second wall portion and the third wall portion cooperatively define a chamber in communication with the opening and configured to receive therein at least a portion of the shaft of the hemostat-style surgical instrument, wherein the at least a portion of the shaft is received in the chamber from an off-axis position. ## Claims ### Claim 1 A surgical instrument, comprising: a hemostat-style device, including: first and second shaft members each defining a proximal end and a distal end; first and second handle members disposed at the proximal ends of the respective first and second shaft members; and first and second jaw members extending distally from the distal ends of the respective first and second shaft members, wherein the first and second shaft members are operably coupled to one another towards the distal ends thereof such that movement of the first and second handle members between an open position and a closed position moves the first and second jaw members between a spaced-apart position and an approximated position; and a clip-over assembly, including: a body including first, second, and third wall portions cooperating to define a chamber therein and an opening providing access to the chamber, wherein the first shaft member of the hemostat-style device is configured for insertion through the opening and into the chamber to releasably engage the first shaft member within the chamber of the body; and first and second finger actuators operably coupled to the body and positioned such that, with the first shaft member releasably engaged within the chamber of the body, the first finger actuator is disposed on a first side of the first shaft member and the second finger actuator is disposed on a second, opposite side of the first shaft member. ### Claim 2 (depends on 1) The surgical instrument according to claim 1, wherein the first and second finger actuators are positioned such that, with the first shaft member releasably engaged within the chamber of the body, the first shaft member is disposed on one side of first and second finger actuators, and the second shaft member is disposed on a second, opposite side of the first and second finger actuators. ### Claim 3 (depends on 1) The surgical instrument according to claim 1, wherein at least a portion of each of the first and second shaft members is formed from an electrically-conductive material. ### Claim 4 (depends on 3) The surgical instrument according to claim 3, wherein the body of the clip-over assembly is formed from an electrically-insulative material. ### Claim 5 (depends on 1) The surgical instrument according to claim 1, wherein the body of the clip-over assembly includes a proximal portion having the first and second finger actuators operably disposed thereon and an elongated distal portion extending distally from the proximal portion. ### Claim 6 (depends on 1) The surgical instrument according to claim 1, wherein the body of the clip-over assembly is formed via injection molding. ### Claim 7 (depends on 1) The surgical instrument according to claim 1, wherein at least one of the first or second finger actuators includes an electrical switch. ### Claim 8 (depends on 7) The surgical instrument according to claim 7, wherein, with the first shaft member releasably engaged within the chamber of the body, the at least one electrical switch is selectively actuatable to supply energy to at least one of the first or second jaw members. ### Claim 9 (depends on 1) The surgical instrument according to claim 1, wherein at least one of the first or second finger actuators includes a joystick. ### Claim 10 (depends on 1) The surgical instrument according to claim 1, wherein at least one of the first or second finger actuators includes a button.
