Abstract

The invention discloses a brain buried pipe medicine applying cannula capable of recording cell external electric potential. The brain buried pipe medicine applying cannula capable of recording the cell external electric potential comprises a buried pipe cannula body, an electrode cannula, a pipe core cap, a medicine applying pipe, a fixing nut, a wire electrode, a pipe core and a buried pipe cannula cap. The brain buried pipe medicine applying cannula capable of recording the cell external electric potential combines the five functions of stimulation, damage, medicine application and recording as a whole, therefore, experimental operation is simplified, experimental cost is reduced, experimental success rate is improved, and the flexibility and accuracy of devices are improved. The brain buried pipe medicine applying cannula capable of recording the cell external electric potential is simple in structure, convenient to operate and low in manufacturing cost, and well solves the problems that an existing brain buried pipe medicine applying cannula is single in operating function and high in using cost and causes secondary damage easily.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a brain drug delivery cannula capable of recording extracellular potential. Background technique [0002] In neuroscience research, in vivo research is a popular technology at present. Physiological and pharmacological methods and electrophysiological methods are usually used. Physiological and pharmacological methods include brain stereotaxic pharmacological control, fixed-point damage, tissue fluid extraction, etc. Electrophysiological methods include local field Potential, extracellular stimulation and recording methods. In these techniques, implanted catheters in the brain, microinjection needles, electrodes for extracellular EEG recording and stimulation, electrodes for electroablation damage, and implanted catheters for drug delivery in the brain are required. Needles can meet the needs of space-specific administration of intracerebral clusters; extracel...
