A dual-channel acoustic-guided epidural puncture needle is composed of a pressure-taking device, an epidural puncture needle tube, a spinal needle
assembly, a needle seat, and a
syringe pump connector. An
anesthetic catheter channel is arranged inside a needle wall of the epidural puncture needle tube, the end of the
anesthetic catheter channel is provided with a bend needle end, the top of the needle wall is provided with a spinal needle tube channel, the needle seat has a double-channel structure, a spinal needle inlet and an
anesthetic catheter inlet at one end of the needle seat respectively communicate with the spinal needle tube channel and the anesthetic catheter channel of the epidural puncture needle tube, the spinal needle
assembly is composed of a spinal needle, a positioning sleeve and a needle
handle, the spinal needle comprises a spinal needle tube wall and a spinal needle tube cavity, and a connecting tube at an outlet end of the pressure-taking device is connected to the needle seat through a connecting
pipe connector. According to the puncture needle, a double-channel entry structure of the anesthetic catheter and the spinal needle is adopted, the
operation mode of combined spinal-epidural
anesthesia is changed, and the success of the puncture and
anesthesia is guaranteed; and the structure of the spinal needle with the positioning sleeve and the structure of the epidural needle tube with a back hole are provided so that a guarantee is provided for correct implementation of
spinal anesthesia.
