Epidural anesthesia device

Abstract

The invention discloses an epidural anesthesia device, which comprises a fixed plate, a limit sliding plate and an angle adjustment box. A first fixed frame is fixed on the fixed plate through a fixed pin, and the upper end of the first fixed frame passes through a first limit The threaded rod is fixed with a fixed rod, and the upper end of the fixed rod is fixed with a second fixed frame through a fixed pin. The right side of the limiting sliding plate is fixed by two second limiting threaded rods, and the left side of the limiting sliding plate is provided with a limiting sliding column. , the lower end of the limit sliding plate is fixed with a fixing device through connecting rods distributed in an array, the right side of the angle adjustment box is provided with a fixed card tube, and the left and right sides of the angle adjustment box are respectively equipped with a lower angle adjustment device and an upper side angle adjustment device. There is a puncture needle inside the angle adjustment box. The epidural anesthesia device of the present invention solves the problems that the operation of the visual angle during epidural anesthesia is very irregular and the risk of puncture accuracy is high. After the puncture is completed, the fixed anesthesia effect is good, it is easy to disassemble and carry, and does not occupy space.

Description

technical field [0001] The invention relates to an anesthesia device, in particular to an epidural anesthesia device. Background technique [0002] Epidural anesthesia is about injecting local anesthetic into the epidural space to block the spinal nerve root and temporarily paralyze the innervated area, also known as epidural space block anesthesia. According to the way of administration, it can be divided into single method and continuous method. According to the puncture site, it can be divided into high, middle, low and caudal block. In theory, an epidural block can be used for any surgery other than the head. However, from a safety point of view, epidural blocks are mainly used for operations on the abdomen and below, including urology, obstetrics, and lower extremity operations. [0003] Epidural space block anesthesia is commonly used for surgery on extremities below the abdomen. At present, when performing epidural puncture, anesthetists mainly rely on the feeling...

AI Technical Summary

Problems solved by technology

At present, when performing epidural puncture, anesthetists mainly rely on the feeling of falling during the operation to judge that the needle tip of the epidural puncture needle has reached the epidural space. In addition, the position of the puncture needle should be kept fixed during the insertion of the epidural catheter , to prevent the movement of the puncture needle from damaging the dura mater and even the spinal cord, leading to more serious consequences

At the same time, the visual angle operation is very irregular, and some epidural anesthesia devices on the market have cumbersome structures and are inconvenient to carry
