Surgical instrument and method

摘要

An electro-surgical instrument includes a first member extending to an end having a first electrode. A second member extends to an end having a second return electrode. The ends define a spinal tissue cavity and are relatively translatable to selectively adjust the cavity such that the electrodes are oriented to ablate, cut and/or coagulate spinal tissue. Systems and methods are disclosed.

主权项

1. An electro-surgical instrument comprising:
a first member extending between a first end having a first electrode and a second end having spaced apart arms; a second member extending along a longitudinal axis between a first end having a second return electrode and a second end having a slot, the first ends defining a tissue cavity; a lever comprising spaced apart extensions, outer surfaces of the extensions engaging inner surfaces of the arms and an outer surface of the second end of the second member engaging inner surfaces of the extensions; a first pin extending through the arms, the extensions and the slot; and a second pin extending through the extensions and the second end of the second member, wherein pivoting the lever relative to the second member about the second pin translates the first in within the slot to move the first member relative to the second member along the longitudinal axis to selectively adjust a length of the cavity.
