Example Embodiment

[0022] Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings.

[0023] The invention provides a dual-cavity spinal-epidural combined anesthesia integrated puncture needle, which has a structure such as figure 1 As shown, a puncture needle body is included. The puncture needle body includes an epidural catheter lumen 1 and a lumbar puncture needle lumen 2 that are independent of each other. The epidural catheter lumen 1 and the lumbar puncture needle lumen 2 The bodies are arranged side by side, and one end forms side-by-side needles, and the other end is separated from each other; and the other end is provided with a needle seat 3 wrapped outside the epidural catheter lumen 1 and the lumbar puncture needle cavity 2; wherein, One end of the epidural catheter lumen 1 is provided with an epidural catheter outlet 11, one end of the lumbar puncture needle cavity 2 is provided with a spinal anesthesia needle outlet 21, a...

Abstract

The invention provides a combined spinal-epidural anesthesia double-cavity integrated puncture needle which comprises a puncture needle body. The puncture needle body comprises an epidural catheter cavity and a lumbar puncture needle cavity, wherein the epidural catheter cavity and the lumbar puncture needle cavity are independent and arranged side by side, needle heads arranged side by side are formed at one end of the epidural catheter cavity and one end of the lumbar puncture needle cavity, and the other end of the epidural catheter cavity and the other end of the lumbar puncture needle cavity are separated. The other end of the puncture needle body is provided with a needle base wrapping the epidural catheter cavity and the lumbar puncture needle cavity; one end of the epidural catheter cavity is provided with an epidural catheter outlet, and the other end of the epidural catheter cavity is provided with an epidural catheter inlet; one end of the lumbar puncture needle cavity is provided with a lumbar anesthesia puncture needle outlet, and the other end of the lumbar puncture needle body is provided with a lumbar anesthesia puncture needle inlet. The puncture needle can avoid the problem that an epidural catheter cannot be smoothly embedded after lumbar anesthesia and prevents the situations that anesthesia is adversely influenced and a plane is blocked.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-cavity combined spinal-epidural anesthesia integrated puncture needle. Background technique [0002] Combined spinal anesthesia has become one of the preferred anesthesia methods for various operations on the lower abdomen and lower limbs. Combined spinal anesthesia has the advantages of quick onset, good block effect, and unlimited anesthesia time. The combined spinal-epidural anesthesia puncture needle used at this stage is a needle-in-needle, which often occurs when the epidural catheter is blocked after the spinal anesthetic is injected or the epidural catheter is not placed smoothly, resulting in the inability to perform the spinal canal. Combined anesthesia. Specifically, when using the existing combined spinal epidural anesthesia puncture needle for intraspinal combined anesthesia, the patient is placed in the lateral position, and after successful epidu...
