The invention discloses a comprehensive testing device for
sciatic nerve trunks, motor nerves and skeletal muscles. The comprehensive testing device comprises a specimen bearing
assembly composed of PU plates, an electrophysiological
signal collecting and stimulating
assembly composed of
acupuncture needles and miniature
alligator clips, and a
muscular tension testing
assembly composed of a support and a tension
transducer. The PU plate can fix an in-vitro spine-
spinal nerve-
sciatic nerve trunk-
tibial nerve-
gastrocnemius muscle integrated active specimen of a frog, and the
acupuncture needle can puncture an
adventitia and is arranged between nerve
fascia membranes or puncture an
adventitia of
skeletal muscle and is arranged between
muscular fascia membranes and is connected with a biological function data analyzer, so that electrical stimulation application and
electric signal and electromyographic
signal acquisition are realized, and the biological function data analyzer is connected with a biological function data analyzer. The tension
transducer is connected with the specimen and synchronously collects
muscular tension signals. Neural and
muscle testing functions are integrated, the use amount of experimental animals is reduced, the
signal-to-
noise ratio of signals is increased through
acupuncture needle puncture type collection, the PU plate is flexible in
adaptation, the
electrode distance is adjustable, and neural electrophysiological signals and
muscular tension signals can be synchronously obtained.
