Nerve plexus stimulation system, nerve plexus stimulator and nerve plexus stimulation method

Abstract

The invention discloses a nerve plexus stimulation system, a nerve plexus stimulator and a nerve plexus stimulation method, which are designed to solve the problem of inaccurate nerve plexus positioning in the conventional peripheral nerve block operation. The nerve plexus stimulation system comprises the nerve plexus stimulator, an auxiliary electrode and a nerve plexus stimulating needle, wherein the auxiliary electrode and the nerve plexus stimulating needle are connected with the nerve plexus stimulator through connectors; and the nerve plexus stimulator comprises a working parameter regulating and setting module, a microprocessor, a simulative impulse transmission and control module, a display module and a power supply module. Based on the structure and simulation method, the system can position the nerve plexus objectively, directly and accurately, and thus, problems of the conventional subjective and unquantized blink detection method are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a nerve plexus stimulation system, a nerve plexus stimulator and a stimulation method. Background technique [0002] Peripheral nerve block is a necessary step in many surgical operations, and accurate positioning of the nerve plexus is the key to successful block surgery. The traditional peripheral nerve block operation combined with anatomical diagrams adopts the blind detection method, which relies on the doctor's experience and the patient's feedback on the abnormal sensation to judge whether the injection needle tip has reached the appropriate position. This method is difficult to accurately locate the nerve plexus and cannot be performed if the patient is unconscious or uncooperative. Especially if the patient is obese, the effect of this method becomes very limited due to the accumulation of a large amount of fat on the body surface and the inconspicuous anatomical landmark...
