Abstract

The invention discloses a combined spinal-epidural anesthesia puncture needle, comprising a puncture needle tube (1), an epidural anesthesia canal and a spinal anesthesia puncture needle, characterized in that the puncture needle tube (1) is provided with an epidural anesthesia canal introducing tube cavity (2) in the middle, a spinal anesthesia puncture needle introducing tube cavity (3) in the rear. According to the invention, the combined spinal-epidural anesthesia puncture needle tube is punctured in the spinal space, and the epidural anesthesia canal introduced in the epidural anesthesia canal introducing tube cavity is introduced in the epidural cavity, when the epidural anesthesia canal is in the right position, the spinal anesthesia canal introduced in the spinal anesthesia puncture needle introducing tube cavity is punctured in the spinal-epidural subarachnoid space to administrate anesthetics for the smooth operation.

Description

1. Technical field: [0001] The invention relates to a medical device, in particular to a combined spinal-epidural anesthesia puncture needle for surgical operations below the waist and abdomen. 2. Background technology: [0002] At present, the known combined spinal epidural anesthesia puncture needle used for surgical operations below the waist and abdomen includes a puncture needle tube, an epidural anesthesia catheter and a spinal anesthesia puncture needle. The puncture needle tube has a lumen, and the puncture needle tube is first inserted into the The patient's lumbar intervertebral space, and then insert the spinal anesthesia puncture needle into the lumen of the puncture needle tube, puncture the spinal anesthesia puncture needle into the subarachnoid space and inject anesthetic, pull out the spinal anesthesia puncture needle, and then insert the epidural anesthesia catheter into the puncture The lumen of the needle tube is inserted into the patient's lumbar epidural...
