Problems solved by technology

Therefore, in clinical surgery, after the bioelectrode is implanted in the correct position, a special fixer must be used to fix the bioelectrode on the patient's skull, otherwise the bioelectrode may be displaced in the patient's body during the subsequent treatment, causing the biological The electrode deviates from the target position, resulting in a decrease in the stimulation effect of the bioelectrode or even a failure of the operation

Embodiment Construction

[0026] As shown in FIGS. 1 to 7 , the biological electrode holder provided by the present invention is mainly composed of four parts: a base 1 , a right fixing plate 3 and a left fixing plate 4 , a gasket 5 and a protective cover 2 . The fixed plate is composed of a right fixed plate 3 and a left fixed plate 4, which can cooperate with each other after being assembled on the base 1 to form a clamping mechanism. The right fixed plate 3 is assembled on the base 1, and the slider 10 of the right fixed plate 3 rotates in the irregular track 7 of the base, so that the position of a certain fixed hole on the right fixed plate is just in line with the implanted biological The positions of the electrodes coincide, and then, the left fixing plate 4 shown in Fig. 5(a) is installed on the boss 11 of the right fixing plate 3, and the left fixing plate and the right fixing plate cooperate with each other to realize the clamping of the electrodes. Cover the washer 5, fix the right fixing pl...

Abstract

The invention discloses a fixer used for fixing a bioelectrode, in particular to a bioelectrode implanted into the deep brain of the human body, so that the fixer can play a role in fixing well. The fixer used for fixing the bioelectrode mainly comprises a base, a protective cover, a fixing plate and a gasket, wherein the fixer can be accurately fixed in a skull hole of a patient through the ladder-shaped base; an irregular rail on the base can guarantee that the bioelectrode is fixed and clamped on the correct position through a fixing hole in a proper position when the bioelectrode is located in any position in the skull hole plane; the fixing plate is pressed on the base through the gasket; and after the bioelectrode is drawn from a groove at the electrode leading-out terminal of the base, and the protective cover is pressed, so that sealing between the hole formed in the skull of the patient and the fixer can be achieved, and the fixing of the bioelectrode can be finished.

Description

technical field [0001] The invention relates to a biological electrode holder. Background technique [0002] In clinical medicine, for the treatment of more serious neurological disorders, such as Parkinson's disease, severe epilepsy, hearing nerve disorders, optic nerve disorders, or drug rehabilitation, the most effective treatment method is to perform surgery on the deep part of the patient's brain. Bioelectrodes are implanted at the target site for a long time, and the neural nuclei at the target site are stimulated by electric discharge to treat or improve the patient's condition. The implanted bioelectrodes used in current clinical treatment are generally millimeter-scale cylindrical electrodes, and the therapeutic effect mainly depends on the accuracy of the implanted target position of the bioelectrodes. In addition, after the bioelectrode is correctly implanted into the brain target position during surgery, the accuracy of the location of the bioelectrode and the a...
