A grounding pad
was placed on the thigh to complete the electrical circuit.
Lewis explains, the energy enters the patient through the tip of the device and in order to exit, it must go through the patient to a grounding pad
The alternating current passed back and forth through the patient between the grounding pad
and the Bovie knife.
One recent modeling project involved the development of a revolutionary electrosurgical grounding pad
Prior to the advent of these probes, the unipolar configuration, consisting of a small treatment electrode and a large grounding pad
attached to the patient's leg, was the type conventionally used in arthroscopy.
The grounding pad
collects the current and completes the circuit.
When treating CTS, the MicroStim 100 TENS device's blinking red light circular lead electrode is attached through a sticky patch to the center of the wrist crease, and the grounding pad
to the opposite side of the wrist.
3M Brings Grounding Pad
Technology Out of Hibernation
Because electromagnetic field solvers are now commercially available, a MMIC grounding pad
with via holes can be analyzed and an optimum topology for broad-band performance free of spurious signals can be found.
The device, which is indicated forcutting and coagulation of tissue in open and laparoscopic surgery, provides surgeons with an electrically neutral surgical option that does not require a grounding pad
, and eliminates the risk of alternate site burns.
Furthermore, no grounding pad
is required as with other electrosurgical products, minimizing the risk to the patient and surgeon.
