Embodiment 1

[0052] Example 1: The current released by radio frequency directly forms a high voltage near the neuralgia point, which can directly remove the inflammatory factors of the diseased tissue, play a role in eliminating edema and toxic reactions, and help to weaken the phenomenon of abnormal discharge in the sensory nerve , thereby relieving postherpetic neuralgia.

[0053]Since the herpes zoster virus mainly damages the dorsal root ganglion of the spinal cord, the effect of radio frequency acting directly on the dorsal root ganglion is the best in the treatment of postherpetic neuralgia. However, since the radio frequency needle is a straight metal needle, the dorsal root The ganglion is located inside the bone of the spine, and the puncture needle cannot directly touch the dorsal root ganglion. Therefore, this radio frequency catheter is designed to perform radiofrequency treatment from the spinal column and the epidural space to the dorsal root ganglion.

Abstract

The invention discloses a bendable intraspinal radio frequency catheter device, which belongs to the technical field of surgical instruments and comprises a catheter part, the catheter part is used for performing interspinous puncture and reaching dorsal root ganglion through epidural space in the spine, and the tip of the catheter is a metal exposed end so as to facilitate radio frequency conduction; the radio frequency part is connected with the catheter part and used for providing current for the catheter part reaching the dorsal root ganglion and forming high temperature and high voltage to adjust or damage nerves, and the radio frequency part penetrates through the catheter part; the handle part is connected with the catheter part and is used for controlling the end part of the catheter part to swing left and right; the radio frequency device in the spine can reach the ganglion part of the dorsal root through puncture in the spine, so that the purpose of performing a radio frequency operation from the inside of the spine is achieved.

Description

technical field [0001] The present application relates to the technical field of surgical instruments, in particular, to a bendable intraspinal radio frequency catheter device. Background technique [0002] RF instruments are generally equipped with monitoring functions such as self-test, nerve stimulation, current, voltage, power, temperature, impedance, damage mode, and even heating curves. Doctors control the temperature and time of needle tip heating by adjusting the magnitude and duration of the electric current, which plays a role in controlling the size of the damaged area. In principle, first put the puncture trocar into the radio frequency action point, the needle shaft of the whole puncture needle is insulated, and only the exposed part of the tip of the needle can transmit current. Then put the thermoelectric electrode that can transmit the current generated by the instrument and feedback the temperature of the needle tip into the trocar, and form a thermocoagula...
