Objective To develop a kind of wire-reinforced epidural catheter with independent intellectual property rights and evaluate its clinical effect. Methods Through a series of studies, amd spring coil, coat of plastic pipe, catheter tip shape and printing calibration have been designed and made. Complete steel wire reinforced epidural catheters by using advancing modeling technology of the plastic pipe spring coil and coat. Results Clinical application effect of the evaluation results revealed that home-grown wire-reinforced catheter was superior to ordinary epidural catheter. Compared with U.S. ARROW production of the wire-reinforced epidural catheter, there was no signiifcant difference in the complication indicators of epidural anesthesia. Conclusion The wire-reinforced epidural catheter can signiifcantly reduce the damage of nerve and vascular by insertion of epidural catheter, and decrease medical risks. With an obvious price advantage, the domestic wire-reinforced catheter is worthy of clinical application.
