Detailed description of the invention
As shown in Fig. 1 to 7, Bioelectrode fixer provided by the invention is primarily of pedestal 1, right fixing head 3 and left fixing head 4, packing ring 5 and over cap 2 four part composition.Fixing head is made up of right fixing head 3 and left fixing head 4, is assemblied in after on pedestal 1 and can cooperatively interacts, and forms a clamp system.Right fixing head 3 is assemblied on pedestal 1, rotated in the irregular track 7 of pedestal by the slide block 10 of right fixing head 3, the position of certain fixing aperture on right fixing head can be made just in time to overlap with the position of the bioelectrode implanted, then, left fixing head 4 shown in Fig. 5 (a) is arranged on the boss 11 of right fixing head 3, left fixing head and right fixing head cooperatively interact, and realize the clamping to electrode.Cover packing ring 5, right fixing head 3 and left fixing head 4 are fixed, make it no longer rotate, thus realize the location of electrode in its tram.By bioelectrode from the base electrode lead-out groove 9 position pull-out of pedestal 1, the clamping block 18 on over cap 2 is pressed in the protection draw-in groove 8 of pedestal, realizes the location of bioelectrode and the sealing of holder.
The material of Bioelectrode fixer provided by the invention is the medical macromolecular materials that biocompatibility is good, is non-degradable material, as polyurethane, polyethylene, polypropylene, polyacrylate, aromatic polyester, polysiloxanes etc.
Bioelectrode fixer concrete structure provided by the invention is as follows:
Pedestal 1 as shown in Fig. 3 (a) is ladder-type structure, and the size of bottom circular step is identical with the diameter dimension of institute's perforate in patient's skull, for the location of Bioelectrode fixer in patient's skull; Pedestal 1 center has a through hole 6, is bioelectrode implantation position, by this through hole 6, bioelectrode can be passed in the middle of invented Bioelectrode fixer during surgical operation.The outward flange of pedestal is uniformly distributed four base electrode lead-out grooves 9, bioelectrode can be made to fix the pull-out of one of them groove direction of tailing edge, and do not affect over cap seal holder.
Right fixing head 3 is as shown in Figure 4 and Figure 5 assemblied on pedestal 1 together with left fixing head 4, can form location and the fixture of bioelectrode.During assembling, round slider 10 in right fixing head 3 embeds the irregular track 7 of spill in pedestal 1, freely can rotate in the irregular track 7 of pedestal 1, stop when the position turning to certain fixing aperture on right fixing head 3 just in time overlaps with the position of the bioelectrode implanted.Then, be arranged on by the little groove 14 of left fixing head 4 on the boss 11 of right fixing head 3, the cooperation of little groove 14 and boss 11 can make left fixing head 4 on pedestal, do rectilinear motion or rotary motion.Rotate left fixing head 4, the clamp 16 of left fixing head 4 is clamped in the clamping slot 13 of right fixing head 3, realizes the firm connection of right fixing head and left fixing head.Now, the right profile 12 of fixing aperture of the fixing aperture left profile 15 on left fixing head 4 and right fixing head 3 centre is combined, and forms the closed circular hole that is dimensioned slightly smaller than bioelectrode diameter dimension, realizes the clamping to bioelectrode by interference fit.
Right fixing head 3 as shown in Figure 4 and Figure 5 and left fixing head 4 have interchangeability.The bioelectrode possibility size that different patients implants is different, can have the fixing head of the fixing hole diameter of applicable size according to the bioelectrode size Selection implanted.
Right fixing head 3 as shown in Figure 4 and Figure 5 and left fixing head 4 are provided with multiple fixing aperture, due to track 7 irregularly shaped of pedestal 1, no matter bioelectrode be positioned at after implanting patient's skull the optional position of hole plane of holing, it all can ensure fixing head to have at least the position of a fixing aperture and bioelectrode position coincide, fixing head electrode position when clamping bioelectrode can be made like this not to be moved, thus to realize Stability and veracity when bioelectrode is fixed.
Bioelectrode be fixedly that the position of left fixing head 4 is determined by right fixing head 3 by after the optimum fixation position that rotated in the irregular track 7 of pedestal 1 by right fixing head 3, carried out coordinating realizing with right fixing head 3 by left fixing head 4 again.Therefore after bioelectrode is fixed on fixing head centre, fixing head also must be fixed, in order to avoid fixing head rotates again, affect the position of bioelectrode.
The present invention adopts the fixing head of packing ring 5 pairs of holders to be as shown in Figure 6 fixed, and its material can adopt the material that biocompatibility is good and elasticity is good, as rubber etc.After bioelectrode is fixedly clamped by right fixing head 3 and left fixing head 4; packing ring 5 is embedded pedestal 1 and between right fixing head 3 and left fixing head 4; after press-in over cap 2; the elasticity of rubber washer 5 makes it fill up pedestal 1, space between fixing head (right fixing head 3 and left fixing head 4) and over cap 2; elastomeric material due to packing ring 5 has larger expansive force and frictional resistance; fixing head can not move freely again, thus realize the fixing of fixing head.After fixing head is fixed, the position of bioelectrode is just accurately positioned and is clamped.By closed patient's skull is holed hole, an over cap is adopted Bioelectrode fixer to be closed.Over cap 2 is designed with four clamping blocks 18; four clamping slots 8 be positioned on pedestal 1 can be embedded; after assembling, over cap 2 also contacts with rubber washer 5; rely on larger frictional force existing between rubber washer 5 and over cap 2; over cap is stably embedded between pedestal 1 and rubber washer 5, achieves the sealing to Bioelectrode fixer, avoid the exposed of holder and patient's skull hole; over cap 2 is provided with electrode and draws groove 17, for coordinating extraction electrode with base electrode lead-out groove 9.
