Abstract
The invention belongs to a kind of medical apparatus and instruments, is to be used to discern cranial nerve and perineural instrument in the clinical department of stomatology, department of otorhinolaryngology and the surgical operation.It is made up of anodal probe (1), needle stand (2) and handle (3), lead (11) and negative pole probe (4), and three resistance are arranged in the handle (3); Can divide 0.3mA, 0.6mA and 1mA three retainings.This product has the physiological requirement of meeting, and volume is little, and retaining is inferior many, advantage such as easy and simple to handle, at the various identification peripheral nerves that need, all can use the particularly discriminating of nerve and identical in department of otorhinolaryngology and microsurgery in the operation with difference muscle and connective tissue etc.
Description
The invention belongs to a kind of medical apparatus and instruments, is to be used to discern cranial nerve and perineural instrument in the clinical department of stomatology, department of otorhinolaryngology and the surgical operation.
The unidirectional current nerve stimulator of Chinese patent 89204024.6, after power supply passes through its resistance, electric current has only class of 0.6mA, in use, big for the nerve stimulation insufficient strength that partial denaturation or outmoded injury are arranged, and stimulus intensity seems excessive during for the apposition suture of nerve tract.On the other hand, because its probe is a double end, in department of otorhinolaryngology and microsurgery, can not use.
The object of the present invention is to provide a kind of be easy to discern cranial nerve and perineural, new DC electro-neural stimulator instrument.
The present invention is achieved in that it is made up of anodal probe (1), needle stand (2) and handle (3), lead (11) and negative pole probe (4), and it is fixing that anodal probe (1) inserts needle stand (2), and needle stand (2) is socketed in the handle (3), and rotatable; Interior resistance (5), (6), (7) of anodal probe (1) and handle (3) rotate to relative position respectively and are connected, resistance (5), (6), (7) are 120 ° of distributions, their other end is connected with battery (8) by a copper sheet, the negative pole of battery (8) links to each other with spring (9), spring (9) is connected with the positive pole of light emitting diode (10), light emitting diode (10) is connected with lead (11), and lead (11) passes the back from handle (3) afterbody and is connected with negative pole probe (4).
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is a front view of the present invention.
Fig. 2 is a profilograph of the present invention.
The present invention is made up of anodal probe (1), needle stand (2), handle (3), lead (11) and negative pole probe (4); Anodal probe (1) is made for stainless steel material, is about 38mm, and diameter is less than 1mm, and is blunt nosed, isometric, and it is fixing that it inserts needle stand (2), and needle stand (2) is socketed in the handle (3), and rotatable; Interior electricity group (5), (6), (7) of anodal probe (1) and handle (3) rotate to relative position respectively and are connected, resistance (5), (6), (7) are 120 ° of distributions, their other end is connected with battery (8) by a copper sheet, battery (8) links to each other with spring (9), spring (9) is connected with the positive pole of light emitting diode (10), light emitting diode (10) is connected with lead (11), and lead (11) passes the back from handle (3) afterbody and is connected with negative pole probe (4).Resistance (5) is 40K Ω, and resistance (6) is 20K Ω, and resistance (7) is 12K Ω.Battery (8) is single 12V battery, and light emitting diode (10) voltage is 1.5～2V, plays display lamp.Handle (3) is cylindrical, is about 88mm, the about 15mm of diameter.
After electric current passes through resistance (5), electric current is 0.3mA, conduction causes anodal probe (1), the bundle that directly excites nerve, electric current is transmitted to surrounding tissue through nerve trunk, and negative pole probe (4) contacts with surrounding tissue, electric current is back to original position by negative pole probe (4) by lead (11), light emitting diode (10) and spring (9), finish one-period like this, the nerve of institute's irriate just produces action potential, makes ridden muscle corresponding sports.After electric current passes through resistance (6), electric current is 0.6mA, conduct to anodal probe (1), the adventitia that directly excites nerve, electric current is transmitted to surrounding tissue through nerve trunk, and negative pole probe (4) contacts with surrounding tissue, electric current is back to original position by negative pole probe (4) by lead (11), light emitting diode (10) and spring (9), finish second period like this, the nerve of institute's irriate just produces action potential, makes ridden muscle corresponding sports.After electric current passes through resistance (7), electric current is 1mA, conduct to anodal probe (1), the adventitia that directly excites nerve, electric current is transmitted to surrounding tissue through nerve trunk, and negative pole probe (4) contacts with surrounding tissue, electric current is back to original position by negative pole probe (4) by lead (11), light emitting diode (10) and spring (9), finish the 3rd cycle like this, the nerve of institute's irriate just produces action potential, makes ridden muscle corresponding sports.Every stimulation is once moved once, according to the resting potential of human nerve be-70～-90mV, action potential is 20～40mV, when the people when giving the electricity irritation of This move current potential, can show as the function corresponding effect.
Using method of the present invention: before the operation this product is placed on 40% formalin gas vapor sterilize 40 minutes standby.The neural suitably exposure of being examined and determine, print blood stasis liquid during operation, with the nervous tissue that probe one end in contact is examined and determine, the other end contacts its surrounding tissue, just can observe its reaction.Can rotate to the 0.3mA class when coincideing when neural, be used as when normal neuro anatomy is detected and can rotate to the 0.6mA class, then rotate to the 1mA class when being used as the neurologic examination of the nerve of outmoded injury or partial denaturation at microscopically.
Advantage of the present invention is: (one) meets physiological requirement, and is safe and reliable, can quick and precisely identify nerve, shortens operating time; (2) volume is little, and class is many, and is easy and simple to handle; (3) at the various identification peripheral nerves that need, all can use the particularly discriminating of nerve and identical in ear-nose-throat department and microsurgery with the operation of difference muscle and connective tissue etc.; (4) difference kinesitherapy nerve (bundle) and sensory nerve (thorn); (5) checking injured nerve or tumour surround neural after function whether completely lose, and can verify whether correct contraposition of nerve fibre after coincideing.
