Abstract
The utility model discloses an implantable stimulating and guiding device for the action potential of animal nerves. The device comprises a nerve stem vector, a simulating electrode couple and a guiding electrode couple, and is characterized in that the nerve stem vector is a bar-shaped nontoxic insulator; and a groove used for being embedded into a nerve stem to be measured is formed in the length direction of the nerve stem vector; the simulating electrode couple is arranged at one end of the groove; the guiding electrode couple is far away from the simulating electrode couple and arranged at the other end of the groove; and guide wires of the simulating electrode couple and the guiding electrode couple are simultaneously in contact with the nerve stem to be measured and are led out from the same side of the nerve stem vector.
Description
Technical field
This utility model relates to a kind of biotic experiment device, particularly a kind of stimulation and guiding device of implantable animal nerve action potential.
Background technology
The mensuration of nerve action potential is biomedical, particularly the common technology in the neuro physiology research.At present, relevant prior art comprises: (1) adopt separated nerve trunk more, carries out external test, and shortcoming is to observe and to study a lot of factors at body.(2) also have at body separation nerve; adopting the tip is hook-shaped shield electrode; nerve trunk is provoked; nerve is stimulated and the current potential guiding, and the shortcoming of this method is that the tractive of electrode can cause damage to nerve; in addition; since shield electrode stop that tested nerve trunk often will be exposed in the air, become dry easily, necrosis.The shortcoming of above prior art brings inconvenience for the stimulation and the guiding of nerve action potential, the accuracy of influence experiment.
Summary of the invention
The purpose of this utility model be to provide a kind of perform the operation implant animal intravital, finish at body that nerve action potential stimulates and the device of guiding.
For reaching above purpose, this utility model takes following technical scheme to be achieved:
A kind of implantable animal nerve action potential stimulates and guiding device, comprise that nerve trunk carrier, stimulating electrode are to right with leading electrode, it is characterized in that, described nerve trunk carrier is a bar-shaped nontoxic insulator, have a groove that is used to embed nerve trunk to be measured along its length direction, described stimulating electrode is to being arranged on groove one end; Leading electrode to away from stimulating electrode to being arranged on the groove other end, the right seal wire of stimulating electrode pair and leading electrode contacts with nerve trunk to be measured simultaneously, and draws from the same side of nerve trunk carrier.
In the such scheme, described stimulating electrode pair and leading electrode are to being enclosed with insulation sleeve on the seal wire of drawing the nerve trunk carrier part.Described leading electrode is to being 5～10cm away from the right distance of stimulating electrode.The cross section of described nerve trunk carrier can be circle, semicircle, triangle, rectangle or square.
Device of the present utility model can be made a series of different sizes, is convenient to measure the nerve trunk of different length and diameter; Nerve trunk carrier softness, insulation can be wrapped in nerve to be measured wherein, prevent its exsiccation, necrosis.Both can be used for the exsomatizing guiding of nerve action potential of this device again can be by operation, implants in the animal body on the nerve trunk to be measured, and behind the sew up wound, forming the live body mode stimulates with current potential animal nerve and guide.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is that the C of Fig. 1 is to view (vertical view).
Among Fig. 1 Fig. 2: 1, nerve trunk carrier; 2, nerve trunk to be measured; 3, groove; 4, stimulating electrode is right; 5, electrode sleeve; 6, leading electrode is right.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of implantable animal nerve action potential stimulates and guiding device, the stimulating electrode that comprises nerve trunk carrier 1, makes by seal wire (preferred filamentary silver) to 4 and leading electrode to 6, the nerve trunk carrier is by a bar-shaped nontoxic insulator, make as polyethylene, its cross section can be circle, semicircle, triangle, rectangle or square.Present embodiment adopts semicircle barred body, has a groove 3 that is used to embed nerve trunk to be measured (its cross section also is semicircle) along its semi-circle plane length direction, and stimulating electrode is arranged on groove one end to 4; Leading electrode to 6 away from stimulating electrode to being arranged on the groove other end, the distance between them can be 5～10cm, is preferably 3～8cm.The right seal wire of stimulating electrode pair and leading electrode contact with nerve trunk 2 to be measured simultaneously, and draws from the same side of nerve trunk carrier 1, is enclosed with insulation sleeve 5 on the seal wire of extension, nerve trunk matrix is in addition impacted when avoiding device to implant.
Claims (4)
1, a kind of implantable animal nerve action potential stimulates and guiding device, comprise that nerve trunk carrier, stimulating electrode are to right with leading electrode, it is characterized in that, described nerve trunk carrier is a bar-shaped nontoxic insulator, have a groove that is used to embed nerve trunk to be measured along its length direction, described stimulating electrode is to being arranged on groove one end; Leading electrode to away from stimulating electrode to being arranged on the groove other end, the right seal wire of stimulating electrode pair and leading electrode contacts with nerve trunk to be measured simultaneously, and draws from the same side of nerve trunk carrier.
2, implantable animal nerve action potential as claimed in claim 1 stimulates and guiding device, it is characterized in that, described stimulating electrode pair and leading electrode are to being enclosed with insulation sleeve on the seal wire of drawing the nerve trunk carrier part.
