Technical Field

The invention belongs to the technical field of anesthesia appliances, and particularly relates to an epidural anesthesia needle adjusting system.

Background

Anesthesia is a common means in the existing medical operation, 1% of lidocaine needs to be infiltrated layer by layer in the operation of an intradermic, subcutaneous and interspinous ligament in the process of performing epidural retention clinical anesthesia from the center, and an anesthesia epidural needle system consisting of corresponding needle tubes, anesthesia catheters, epidural needles and other components is used for determining the injection position and conveying medicines, while the existing anesthesia epidural needle system has no more adjustability in the using and operating process; the fixed injection position needs the patient to move, so that medical staff does not have good control performance; the needle tube does not have a corresponding positioning structure during puncture, so that puncture offset is easy to generate; when the needle tube needs to be pulled out subsequently, the needle tube is not provided with a stable pulling-out auxiliary component, so that the working efficiency of the medical process is reduced to a certain extent.
