Nerve detecting instrument

Abstract

The invention discloses a nerve detecting instrument. The nerve detecting instrument comprises a detecting needle and a current generator, the detecting needle is used for being inserted into the human body to be in contact with the nerves of a person, the current generator is used for sending a stimulation current, the detecting needle is electrically connected with the current generator, and receives the stimulation current output by the current generator and transmits the stimulation current into the nerves, and the current generator comprises a shell and a current circuit arranged in the shell, and the current circuit comprises a power source, an oscillation generating circuit and an amplitude regulating circuit. Through the arrangement of the amplitude regulating circuit, the amplitude value of the current finally output into the detecting needle can be effectively regulated, in this way, the effect of regulating the finally output current can be effectively achieved, the nerve detecting instrument can be well applicable to different human bodies, and the using cost of the nerve detecting instrument is lowered.

Description

technical field [0001] The present invention relates to a detection device, more specifically to a nerve detector. Background technique [0002] It is well known that there are various nerves distributed in every animal and human body. These nerves are used to control muscle movement or feed back signals to our brain, so that our brain can respond. Therefore, the nerves are quite important in the body of humans and animals. Therefore, with a sensor all over the body and a signal pathway all over the body, the communication between each body of the body and the brain can be realized by using nerves, so that the brain can control the actions of each body of the body. [0003] The communication method between each nerve is transmitted in the form of electric current, that is to say, by applying electric current to one end of the nerve, and then according to which body of the animal moves after the electric current is applied, it can be judged which nerve is which. Therefore, t...

Problems solved by technology

[0003] The communication method between each nerve is transmitted in the form of electric current, that is to say, by applying electric current to one end of the nerve, and then according to which body of the animal moves after the electric current is applied, it can be judged which nerve is which. Therefore, the current generator is very important, so that the doctor can connect the corresponding nerves to each other well, and the existing current generator can only adjust the frequency of the current input to the nerve, but not the current amplitude, and each nerve has an action potential, that is, when this potential is reached, the current will flow in the nerve, and the nerve impulse will be generated, and due to the individual differences of each person, the action potential in each person's nerve Action potentials are all different, so a nerve detector cannot detect the nerves of all people, so different nerve detectors need to be used for different people, which will greatly increase the cost of nerve detection
