Radio Frequency Regulated Monitoring Trocars

Abstract

The invention discloses a radio frequency adjustment and control monitoring trocar. The trocar comprises a hollow sleeve in which a radio frequency needle can be inserted and a trocar needle matched with the sleeve, the sleeve comprises a sleeve handle, a sleeve body with an insulating outer wall and a conducting point located at the lower end of the sleeve body, the trocar needle comprises a conducting needle body arranged in the sleeve body and a needle handle arranged at the upper end of the conducing needle body, and the upper end of the conducting needle body penetrates out of the needle handle and then is electrically connected with a nerve electrophysiology monitor through a connecting piece; the connecting piece comprises a first plug, a second plug and a wire, wherein the first plug is electrically connected with the upper end of the conducting needle body, the second plug is matched with an external interface of the nerve electrophysiology monitor, and the wire is connected with the two plugs. The radio frequency adjustment and control monitoring trocar is simple in overall structure, easy to operate and convenient to use, integrates medicine injection, radio frequency adjustment and control, electrophysiology monitor performed on peripheral nervous and other functions and facilitates research and treatment.

Description

technical field [0001] The invention belongs to the field of instruments used for monitoring, diagnosis and treatment, and in particular relates to a radio frequency control monitoring trocar. Background technique [0002] At present, nerve electrophysiological monitoring in clinical operations has been more and more widely used in various clinical operations such as neurosurgery, orthopedics, spinal orthopedics, cardiovascular surgery, ENT, and pain. Because it can objectively and effectively evaluate the integrity of the neurological function of a patient in a state of surgical risk based on changes in the electrophysiological signals of the sensory and motor conduction systems, changes in the bioelectricity of the cerebral cortex, and cerebral blood perfusion, therefore, Nerve monitoring has become an indispensable and important part of clinical surgery to detect the integrity of nerve function, reduce nerve damage, and improve the quality of surgery. Continuous monitori...

Problems solved by technology

[0003] However, at present, in the radiofrequency treatment of peripheral nerves, radiofrequency treatment is mainly performed on the patient's peripheral nerves through radiofrequency; during the treatment process, the frequency and method of radiofrequency are adjusted according to the patient's oral changes in abnormal sensations such as pain, swelling, numbness, etc. , in order to achieve the purpose of treatment; and these abnormal sensations are the subjective standards of the individual patients, and the lack of clear objective standards makes this treatment method produce a variety of adverse reactions. , swelling and other discomfort

[0004] At present, in the surgical treatment of peripheral nerve radiofrequency modulation, there is no electrophysiological monitoring of the nervous system in the target area of ​​responsibility at home and abroad, and the currently known puncture trocars can only be used for drugs and radiofrequency neuromodulation, and cannot achieve peripheral neuropathy. Quantitative monitoring of nerve energy hinders treatment and research
