A wire electrode protective sleeve is internally provided with a wire electrode capable of vertically moving along the wire electrode protective sleeve, and a notch is arranged on the middle upper wall of the protective sleeve vertically. First and second bolt via holes are arranged at the upper end of a bowed bracket. The rods of first and second bolts pass through the first and second bolt via holes respectively, enter into a space in the bowed bracket and are respectively screwed and pass through first and second bolt positioning nuts and first and second mobile blocks. The two bolt positioning nuts are both contacted with the inner wall at the upper end of the bowed bracket and fastened by corresponding rods of the bolts. The wire electrode protective sleeve and the wire electrode are respectively fixed on the two mobile blocks. Different bolts are rotated to respectively move the wire electrode and the wire electrode protective sleeve.

Description
Technical field
This utility model belongs to the design and manufacturing technology field that life sciences is used unit discharge recording electrode propulsion plant and microelectrode.
Background technology
The electrode propeller is the device that life science carries out single neuron activity electric discharge recording indispensability, is used for recording electrode accurately is advanced into the precalculated position.The patent No. is that the Chinese patent file of ZL201220161472.1 has been announced a kind of microelectrode thruster, and the weak point of its existence is: can only advance simultaneously or withdraw from wire electrode and electrode protection interplanting are as a whole.Wire electrode can not allow the large wire electrode protective sleeve of rigidity move on separately and withdraw from after the wire electrode protective sleeve is advanced the brain precalculated position.Because wire electrode distance between two tips wire electrode protective sleeve lower end is very near, thereby the angle that the little wire electrode of rigidity can swing in cerebral tissue is very little, can not be in " floating " state.When cerebral tissue is beaten with heart or head strenuous exercise is when producing small rocking, wire electrode can not rock thereupon synchronously, thereby when being used for the selected unicellular active state of long record, can produce cell and change with wire electrode tip relative position, cause single celled flexible lamp dropout.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of two-way microelectrode thruster and microelectrode are provided.During use, after wire electrode and wire electrode protective sleeve are advanced the brain precalculated position, can allow move on the wire electrode protective sleeve of rigidity and withdraw from, thereby electrode can be imbedded in the head of large-scale or meiofauna for a long time, is used for the selected Cellular electrical activity of long record.
The structure of this utility model microelectrode: establishing one in the wire electrode protective sleeve of a rigidity can be along its wire electrode that vertically moves freely, and the wall of wire electrode protective sleeve middle and upper part is provided with vertical notch.
The structure of the two-way microelectrode thruster of this utility model: the first bolt through-hole and the second bolt through-hole are established in the upper end of a bow-shaped support, the space that enters in the bow-shaped support is passed from the first bolt through-hole by the bar section of the first bolt, the space that enters in the bow-shaped support is passed from the second bolt through-hole by the bar section of the second bolt, the first bolt screws togather successively and passes the first setscrew nut and the first movable block, the second bolt screws togather successively and passes the second setscrew nut and the second movable block, two setscrew nuts all with bow-shaped support upper end inwall contact and fastening with corresponding bolt shank.
Because setscrew nut and bow-shaped support upper end inwall contacts and be fastening with bolt shank, so bolt can not move axially during the bolt shank rotation; Because movable block and bolt shank screw togather, so corresponding movable block can moving axially along axle bolt bar section during the bolt shank rotation.
Use of the present utility model: the wire electrode protective sleeve is fixed on the second movable block, rotates the second bolt and can allow the wire electrode protective sleeve move; Wire electrode is fixed in vertical notch on the self-electrode silk protection jacket wall enters on the first movable block in the protective sleeve, rotate the first bolt and can allow wire electrode move.
The beneficial effects of the utility model: can advance respectively wire electrode and wire electrode protective sleeve by rotating different bolts; After wire electrode and wire electrode protective sleeve are advanced the brain precalculated position, can allow move on the wire electrode protective sleeve of rigidity and withdraw from, thereby what implant in the animal brain deep is " floating " shape wire electrode.Can adjust respectively angle of rake precision and advance distance by the pitch of adjustment screw rod and the length of screw rod.This utility model volume is little, and is lightweight, can allow microelectrode be imbedded at for a long time the animal head, and the long-term chronic record is carried out in selected unicellular some activity.

The specific embodiment
Embodiment: see Fig. 1～4.Establishing one in the wire electrode protective sleeve 1 of one rigidity can be along its wire electrode that vertically moves freely 2.The wall of wire electrode protective sleeve 1 middle and upper part is provided with vertical notch 3.28 millimeters of wire electrode protective sleeve 1 length, 0.1 millimeter of wall thickness, 0.25 millimeter of internal diameter is made by 304 stainless steel tubes.30 millimeters of wire electrode 2 length, 0.15 millimeter of diameter.The space that enters in the bow-shaped support 4 is passed from the first bolt through-hole by the bar section of the first bolt 5, and the space that enters in the bow-shaped support 4 is passed from the second bolt through-hole by the bar section of the second bolt 6.The first bolt 5 screws togather successively and passes the first setscrew nut 7 and the first movable block 8.The second bolt 6 screws togather successively and passes the second setscrew nut 9 and the second movable block 10.Two setscrew nuts all with the upper end inwall contact of bow-shaped support 4 and fastening with corresponding bolt shank.The second movable block 10 is positioned at the top of the first movable block 8.The second movable block 10 is provided with a semicircle long recess 11, the first movable blocks 8 ends and is provided with a through hole 12.It is interior also with glue and the second movable block 10 fastening adhesions that the upper end of wire electrode protective sleeve 1 embeds groove 11, and the wire electrode 2 in the wire electrode protective sleeve 1 passes through hole 12 and uses glue and the first movable block 8 fastening adhesions.Rotate the second bolt 6 and can allow wire electrode protective sleeve 1 move up and down, rotate the first bolt 5 and can allow wire electrode 2 move up and down.13 is the lock screw of setscrew nut 7 among the figure.The pitch of the first bolt 5 and the second bolt 6 is 0.25 millimeter, therefore every rotation bolt one circle, and wire electrode 2 and wire electrode protective sleeve 1 all move 0.25 millimeter downward or upward.The ultimate range that this propeller can advance is 10 millimeters.
