Nerve stimulator

Abstract

The invention discloses a nerve stimulator. The nerve stimulator is characterized by comprising a tooth socket fixing seat with a bandage, a rod connected to the tooth socket fixing seat in a penetrating mode and fixed to the tooth socket fixing seat through a fixing piece, and an electrode component arranged at one end of the rod, wherein the electrode component comprises a sleeve with an internal thread connected to one end of the rod, a screw with one end threaded into the sleeve, and an electrode disposed at the other end of the screw. Compared with the prior art, the nerve stimulator hasthe advantages that the electrode can be quickly positioned and fixed at the disc ala ganglion, so that the disc ala ganglion treatment can be electrically stimulated at the first time.

Description

technical field [0001] The invention relates to a medical device. Background technique [0002] Studies have shown that patients with acute ischemic stroke can obtain significant therapeutic effect by stimulating the disc ala ganglion within 8-24 hours of the onset. The stimulation method adopted in the prior art is implanted electrical stimulation, that is, the stimulation electrodes are implanted in the disc ala ganglion. Those skilled in the art know that the disc ala ganglion is located on the upper palate bone near the throat. Although the bone here is thinner, it is easy to puncture, and it is convenient for observation and positioning, but because it is implantable, it usually needs Use a guiding mechanism (such as the technology disclosed in patent CN201410596936.5) to guide the electrode to the stimulation site and fix it. Since it is a bone puncture, it is relatively easy to puncture from one side of the bone (such as in the oral cavity). However, the guiding mech...

Those skilled in the art know that the disc ala ganglion is located on the upper palate bone near the throat. Although the bone here is thinner, it is easy to puncture, and it is convenient for observation and positioning, but because it is implantable, it usually needs Use a guiding mechanism (such as the technology disclosed in patent CN201410596936.5) to guide the electrode to the stimulation site and fix it. Since it is a bone puncture, it is relatively easy to puncture from one side of the bone (such as in the oral cavity). However, the guiding mechanism must be It is not easy to guide it from the other side of the bone, which brings great difficulties to the implanted treatment, prolongs the time of the implantation operation, and then prolongs the time to start the treatment, and the acute ischemic stroke patient’s Timely treatment is very important, the earlier the treatment, the better the treatment effect and the higher the recovery degree
