Epidural puncture method

Abstract

The invention relates to a puncture device for epidural puncture. The puncture device comprises a puncture assembly and a terminal display and analysis device; the terminal display and analysis deviceis connected with a single chip microcomputer in the puncture assembly and a mechanical arm in a puncture navigation device through cables separately; the puncture assembly comprises a shell, a mechanical sampling module, a posture analysis module, a needle insertion driving motor, a Bluetooth transmitting module, the single chip microcomputer, a power source and an aseptic connector; the mechanical sampling module, the posture analysis module and the needle insertion driving motor are electrically connected with the single chip microcomputer separately, the Bluetooth transmitting module is solidified on the single chip microcomputer, the Bluetooth transmitting module is electrically connected with the single chip microcomputer, the shell is arranged on the mechanical arm, and the asepticconnector is fixed on an output shaft of the needle insertion driving motor. The puncture device solves the technical problem that the effect of epidural puncture detention depends on the experienceof an anesthesiologist, and the failure rate is reduced.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to an epidural puncture method. Background technique [0002] Epidural anesthesia is a widely used clinical anesthesia technique, which has the characteristics of little impact on systemic organs, low incidence of complications, shortened hospital stay, and reduced medical costs. The identification of the epidural space in traditional epidural anesthesia puncture relies on the disappearance of the injection resistance of liquid or air when the tip of the puncture needle passes through the ligamentum flavum, and the anesthesiologist feels the change of resistance during the epidural puncture process with the finger of the anesthesiologist. Recognition of reaching the epidural space is a matter of the operator's competent judgment, and the success rate of epidural puncture and the effect of block are beyond the experience of the anesthesiologist. Due to the many uncertain factors an...

AI Technical Summary

Problems solved by technology

Due to the many uncertain factors and relatively high failure rate of the traditional epidural puncture technique, the technical differences among anesthesiologists are large, and the lack of accurate and objective evaluation standards makes it difficult to meet the requirements of precision medicine.
