Embodiment Construction

[0025] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] The present invention provides an integrated puncture needle for combined spinal epidural anesthesia with single cavity and double channels, which includes a base and a needle tube 1, the needle tube 1 is fixed on the base, and the needle tube 1 is provided on the base. Conducted channel. Such as figure 2 As shown, wherein the needle tube 1 is hollow to form a lumen for the epidural catheter and / or lumbar puncture needle to pass through. Such as figure 1 and figure 2 As shown, the outer diameter of the spinal anesthesia needle is 0.45-0.55 mm, and the outer diameter of the epidural catheter is 0.55-0.9 mm.

[0027] Specifically, such as figure 2 As shown, a channel is provided on the base, one end of the channel communicates with the inner cavity of the needle tube 1 , and the other end has an opening 4 on the base. Under this s...

Abstract

The invention provides a single-cavity two-channel combined spinal-epidural anesthesia integrated puncture needle. The single-cavity two-channel combined spinal-epidural anesthesia integrated puncture needle comprises a base and a needle tube. The needle tube is fixed to the base. The base is provided with channels communicated with the needle tube. The needle tube is hollow, and an epidural catheter and / or an inner cavity through which a lumbar spinal needle penetrates are formed. The external diameter of the lumbar spinal needle ranges from 0.45 mm to 0.55 mm, and the external diameter of the epidural catheter ranges from 0.55 mm to 0.9 mm. By the adoption of the single-cavity two-channel combined spinal-epidural anesthesia integrated puncture needle, epidural anesthesia and lumbar anesthesia can be conducted, and lumbar anesthesia and implantation of the epidural catheter can be conducted at the same time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a single-cavity double-channel 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. [0003] Specifically, when using the existing combined spinal epidural anesthesia puncture needle for intraspinal combined anesthesia, the patient is placed in the lateral position, an...
