Benefits of technology

[0008] The generator can include the ability to generate low frequency pulses to stimulate nerves and to assist in the proper placement of the electrosurgical probe in the location that is causing pain. For example, the generator may include the ability to generate low frequency pulses of 0.1 to 3 ms in duration at a frequency between approximately 2-50 hz.
[0009] Temperature and impedance monitoring can be used to assist the surgeon by automatically adjusting energy delivery

Problems solved by technology

Frequently, this pain is the result of cracks or fissures that develop in the wall of the intervertebral disc

Embodiment Construction

[0069] As shown in FIG. 1, an electrosurgical generator 100 includes a chassis 105, and a front panel 110. The front panel 110 includes a display 115, soft keys 120, arrow keys 125, status indicators 130, an RF output on / off control button 135, a grounding pad receptacle 140, a probe receptacle 145, and a rotary encoder knob 150. Probe receptacle 145 receives a probe 165 via a cable plug 160, a cable 155, and a cable plug 162. The display 115 is, for example, an LCD screen that displays certain information during a surgical procedure, as will be discussed in more detail below with respect to FIGS. 2-3 and 5-10.

[0070] Generator 100 can be used with probes such as, for example, the Smith and Nephew SPINECATH® Intradiscal Catheter, the Smith and Nephew Decompression Catheter, and the Smith & Nephew RF Denervation Probe. The electrosurgical generator 100 is capable of therapy profiles through several modes of operation, including SPINECATH® AUTOTEMP®. (automatic temperature) mode, Deco...

Abstract

An electrosurgical generator that can be used, for example, to provide radio-frequency (RF) energy for localized tissue coagulation, cutting, ablation, and to create lesions in nervous tissue. The generator can provide controls for line power, RF power, setting temperature and/or power, for selecting preset temperature and power combinations, and for selecting programmed treatment profiles. The generator can have a display to display the desired probe and tissue temperature, measured probe impedance, actual probe and/or tissue temperature, delivered power, treatment time, mode setting, preset selection, and messages, and indicators for RF Power On, Stimulation On, and Fault Condition. The generator can include the ability to generate low frequency pulses to stimulate nerves and to assist in the proper placement of the electrosurgical probe in the location that is causing pain.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a divisional of U.S. patent application Ser. No. 10 / 873,289 filed on Jun. 23, 2004. The disclosure of this prior application is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This description relates to electrosurgical generators. [0004] 2. Related Art [0005] Lower back pain is a common ailment and affects many people at some point in their lives. Frequently, this pain is the result of cracks or fissures that develop in the wall of the intervertebral disc. These fissures are filled with small nerve endings and blood vessels, and often are a chronic source of pain. Additionally, the inner disc tissue (nucleus) frequently bulges (herniates) into these fissures in the outer region of the disc, likewise stimulating pain sensors within the disc. [0006] Electrosurgical procedures provide minimally invasive treatment options for treating lower back pain by apply...
