Energy-activation mechanisms for surgical instruments
First Claim
1. A surgical instrument, comprising:
- a housing including an energizable member coupled thereto;
a first activation switch coupled to the energizable member and selectively transitionable from an open condition to a closed condition; and
a cable assembly coupled to the housing at a first end and having a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition, the plug adapted to directly connect to a generator configured to supply electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the generator to initiate the supply of electrosurgical energy to the energizable member.

Abstract
A surgical instrument includes a housing, energizable member, first activation switch, cable assembly, and second activation switch. The housing is operatively associated with the energizable member. The first activation switch is coupled to the energizable member and is selectively transitionable from an open condition to a closed condition. The cable assembly is coupled to the housing at a first end and includes a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition. The plug is adapted to connect to the source of electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the source of electrosurgical energy to initiate the supply of energy to the energizable member.

7. A surgical instrument, comprising:
-
a housing including an energizable member coupled thereto; a first activation switch coupled to the energizable member and selectively transitionable from an open condition to a closed condition to provide a first signal above a first threshold; and a cable assembly coupled to the housing at a first end and having a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition, the second activation switch transitions from the open condition to the closed condition upon receipt of the first signal and configured to provide a second signal above a second threshold upon closure of the second activation switch, the plug adapted to directly connect to a generator configured to supply electrosurgical energy such that transitioning of the second activation switch from the open condition to the closed condition position provides the second signal to the generator to initiate the supply of electrosurgical energy to the energizable member, wherein the second signal is above the second threshold and below the first threshold. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A surgical instrument, comprising:
-
a housing having an energizable member coupled thereto; a first activation switch coupled to the energizable member and selectively transitionable from an open condition to a closed condition; and a cable assembly coupled to the housing at a first end and having a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition, the second activation switch comprising a first member and a second member, the first member movably attached to the first activation switch by a pull wire, the plug adapted to directly connect to a generator configured to supply electrosurgical energy such that the movement of the first activation switch from the open condition to the closed condition tensions the pull wire such that the first member moves from a first position, wherein the first member and the second member are spaced-apart from one another, to a second position, wherein the first member and the second member share a point of contact, the second activation switch transitioning from an open condition to a closed condition upon the first member achieving the second position, wherein, in the closed condition, the second activation switch communicates with the generator to initiate the supply of electrosurgical energy to the energizable member. - View Dependent Claims (15, 16, 17, 18)
