Implementation method of novel combined spinal-epidural anesthesia puncture suite

Abstract

The invention provides an implementation method of a novel combined spinal-epidural anesthesia puncture suite, which comprises the following steps: step S1, during use, a straight puncture needle sequentially penetrates through the skin, an epidural space and an epidural mater to perform subarachnoid space puncture, and after successful puncture, cerebrospinal fluid smoothly flows out from the tail end of the straight puncture needle; s2, withdrawing the straight puncture needle until the cerebrospinal fluid does not flow out, and withdrawing the needle tip of the straight puncture needle to the epidural space; s3, a lengthened guide rod with an internal thread is spirally fixed to the tail end of the straight puncture needle, and then the epidural puncture needle with scales is placed in along the lengthened guide rod; s4, placing the epidural puncture needle into the needle body scale of the straight puncture needle along the straight puncture needle; s5, an injector adapter is placed into the epidural catheter along the epidural puncture needle, and an injector is pressed to conduct drug administration on the epidural space; according to the epidural puncture catheter, the accuracy of epidural puncture catheterization can be improved, and epidural puncture can be effectively carried out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for realizing a novel combined spinal-epidural anesthesia puncture set. Background technique [0002] In the anatomy of the human spinal canal, there is a loose space between the ligamentum flavum and the dura mater, which is called the epidural space. Epidural anesthesia is to inject the drug directly into this space at one time, or by indwelling in this space. Catheter, multiple administrations, plays a role in maintaining long-term anesthesia. [0003] The dura mater and arachnoid are closely connected directly. The puncture needle pierces through the skin layer by layer and reaches the epidural space after breaking through the ligamentum flavum. The needle continues to penetrate the dura mater and arachnoid and then enters the subarachnoid space. Subarachnoid anesthesia involves injecting anesthesia into the space. [0004] In practice, the width of the sub...

Problems solved by technology

However, because of the narrow space in the epidural space, especially in elderly patients, it is difficult to puncture the epidural space, and it is especially easy to mistakenly penetrate deep into the subarachnoid space. A balloon filled with water, and a wet tissue is placed on the surface of the balloon, the water cavity inside the balloon is the subarachnoid space, and the gap between the surface of the balloon and the wet tissue is the epidural space; the needle is directly pierced through the tissue, It is easy to stick into the water polo; but it is difficult to just pierce the needle tip through the paper towel and stay on the surface of the water polo without piercing the water polo
