Surgical generator systems and related methods
First Claim
1. A surgical generator system, comprising:
- a generator configured to provide power for driving a surgical instrument;
an output circuit that includes;
a first transformer comprising a primary coil and a secondary coil and producing a first output at the secondary coil; and
an auxiliary transformer comprising an auxiliary primary coil that receives the first output and an auxiliary secondary coil at which a second output is produced;
a switching element configured to cause the output circuit to switch between outputting the first output and outputting the second output;
a sensor configured to sense a parameter of a tissue; and
a controller coupled to the sensor and the switching element, the controller configured to control the switching element according to the parameter of the tissue sensed via the sensor.

Abstract
Surgical generator systems and related methods are disclosed herein. An exemplary generator system can include one or more auxiliary transformer stages to boost the amount of power applied to low-impedance tissue, or to adjust the output voltage and current delivered to a surgical instrument. The auxiliary transformer stage(s) can be disposed in the generator, in the surgical instrument, and/or in an intermediate component. Exemplary generator systems can also include an accessory box disposed inline between a generator and a surgical instrument to provide expanded functionality to the system. The accessory box can have a ground plane that is isolated from the ground planes of the mains supply, the generator, and/or the surgical instrument to reduce or eliminate patient leakage current.

8. A method of delivering energy to tissue, comprising:
-
engaging tissue with a surgical instrument coupled to a generator configured to provide power for driving the surgical instrument; sensing a parameter of the tissue; selectively switching in an output path from the surgical instrument to a primary transformer disposed in the generator between a first output of the primary transformer and a second output of one or more auxiliary transformers according to the parameter of the tissue; and delivering energy through the output path to the tissue. - View Dependent Claims (9, 10, 11, 12)
