Problems solved by technology

The existing combined spinal-epidural anesthesia puncture needle first penetrates the epidural space with the combined spinal-epidural anesthesia puncture needle, and then the spinal anesthesia needle is inserted into the subarachnoid space through the combined spinal-epidural anesthesia puncture needle lumen to perform spinal anesthesia. Then withdraw the spinal anesthesia needle and then insert the epidural catheter, turn over and adjust the spinal anesthesia level. During this process, when the epidural anesthesia catheter is inserted, the catheter may enter the spider web along the needle hole left by the original lumbar needle in the dura In this case, complications such as high sensory and motor nerve block may occur, the safety factor is low, and improper handling may even affect the patient's life

Abstract

The invention discloses a puncture needle for combined spinal-epidural anesthesia. The puncture needle comprises an epidural puncture needle seat and a spinal anesthesia puncture needle seat, wherein the epidural puncture needle seat is provided with an epidural puncture needle, an epidural anesthesia guide pipe cavity is arranged in the epidural puncture needle, an arc-shaped bent needle opening is formed in a needle tip of the epidural puncture needle, a groove used for penetration of a spinal anesthesia puncture needle is formed on one side, opposite to the arc-shaped bent needle opening, of the outer surface of the epidural puncture needle, an angle is formed between the spinal anesthesia puncture needle seat and the epidural anesthesia puncture needle, and a lower opening of the spinal anesthesia puncture needle seat corresponds to the groove. By the means, the puncture needle for the combined spinal-epidural anesthesia has the advantages of convenience in operation, high precision and safety and small wound.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined spinal epidural anesthesia puncture needle. Background technique [0002] Combined spinal epidural anesthesia combines the advantages of spinal anesthesia and epidural anesthesia, which improves the anesthesia effect and improves the operating technology level. It has been deeply studied and widely used at home and abroad. The existing combined spinal-epidural anesthesia puncture needle first penetrates the epidural space with the combined spinal-epidural anesthesia puncture needle, and then the spinal anesthesia needle is inserted into the subarachnoid space through the combined spinal-epidural anesthesia puncture needle lumen to perform spinal anesthesia. Then withdraw the spinal anesthesia needle and then insert the epidural catheter, turn over and adjust the spinal anesthesia level. During this process, when the epidural anesthesia catheter is inserted, the...
