Clip-over disposable assembly for use with hemostat-style surgical instrument and methods of manufacturing same
A clip-over disposable assembly includes a switch assembly and a disposable body. 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.
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;
first and second jaw members extending distally from the distal ends of the respective first and second shaft members; and
a pivot interconnecting the first and second shaft members 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 for grasping tissue therebetween; and
a clip-over assembly, including:
an elongated body including first and second side walls interconnected by a base wall so as to define a U-shaped configuration, the first and second side walls and the base wall cooperating to define a U-shaped chamber configured to receive the first shaft member of the hemostat-style device and releasably engage the first shaft member therein; and
at least one actuator operably disposed on at least one of the first or second side walls of the elongated body and positioned such that, with the first shaft member releasably engaged within the elongated body, the first shaft member is disposed on one side of the at least one actuator and the second shaft member is disposed on a second, opposite side of the at least one actuator.
2. The surgical instrument according to claim 1 , wherein the at least one actuator includes first and second actuators operably disposed on the respective first and second side walls of the elongated body of the clip-over assembly.
3. 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.
4. The surgical instrument according to claim 3 , wherein the elongated body of the clip-over assembly is formed from an electrically-insulative material.
5. The surgical instrument according to claim 1 , wherein the elongated body of the clip-over assembly includes a proximal portion having the at least one actuator operably disposed thereon and an elongated distal portion extending distally from the proximal portion.
6. The surgical instrument according to claim 5 , wherein, when the elongated body of the clip-over assembly is engaged about the first shaft member, at least a portion of the second shaft member is disposed between the first and second side walls of the elongated distal portion of the elongated body.
7. The surgical instrument according to claim 1 , wherein the elongated body of the clip-over assembly is formed via injection molding.
8. The surgical instrument according to claim 1 , wherein the at least one actuator includes an electrical switch.
9. The surgical instrument according to claim 8 , wherein, when the elongated body of the clip-over assembly is engaged about the first shaft member, the electrical switch is selectively actuatable to supply energy to at least one of the first and second jaw members.
10. The surgical instrument according to claim 1 , wherein the at least one actuator includes a joystick.
