Embodiment 1

[0043] A fast, safe and accurate combined puncture needle, including an epidural puncture needle 1 and an anesthesia needle 2; the epidural puncture needle 1 includes an outer puncture needle body and an arc groove 11; the puncture needle body includes a puncture needle plug 12. Puncture needle stem 13 and puncture needle point 14, the puncture needle stem 13 is tubular, the puncture needle plug 12 is sleeved on one end of the puncture needle stem 13, and the other end of the puncture needle stem 13 is provided with a puncture needle point 14 , the puncture needle point 14 is an elbow, the puncture needle point 14 is provided with a first opening 15, the first opening 15 is located on one side of the puncture needle stem 13, and the other side of the puncture needle stem 13 is provided with a An arc-shaped groove 11 with a clearance fit on the outside of the anesthesia needle 2 stems, the axial direction of the arc-shaped groove 11 is parallel to the axial direction of the punc...

Embodiment 2

[0045] A fast, safe and accurate combined puncture needle described in Embodiment 1, the outer side of the puncture needle barrel 13 is provided with an arc-shaped groove 11 . As one of the implementations of the arc-shaped groove 11, the arc-shaped groove 11 is directly opened on the outer side of the puncture needle barrel 13. In the actual processing process, in order to easily process the arc-shaped groove 11 with a superior arc, the arc-shaped groove 11 can be formed on the opened arc. The edge of shaped groove 11 is provided with raised edge protection.

Abstract

The invention relates to a fast, safe and accurate combined puncture needle, including an epidural puncture needle and an anesthesia needle. The arc-shaped groove is designed as a structure with a superior arc in the radial section, so that when the anesthesia needle slides in the arc-shaped groove, the arc-shaped groove of the superior-arc structure can wrap the anesthesia needle, so that the anesthesia needle will not be in the muscle resistance The bottom is offset out of the arc-shaped groove, so that the anesthesia needle can quickly, safely and accurately enter the subarachnoid space through the arc-shaped groove. When the epidural anesthesia catheter is inserted into the inner cavity of the puncture needle body, the epidural anesthesia catheter will not be mistakenly inserted into the subarachnoid space from the aforementioned wound, which effectively improves the safety and accuracy of anesthesia and avoids medical accidents.

Description

technical field [0001] The invention relates to the technical field of combined epidural space and subarachnoid space anesthesia tools, in particular to a fast, safe and accurate combined puncture needle. Background technique [0002] The traditional way of combined epidural space and subarachnoid space anesthesia is to insert the needle of the epidural puncture needle into the epidural space, and then insert the anesthesia needle through the inner cavity of the epidural puncture needle and place it on the spinal cord. Under the guidance of the extramembranous puncture needle, it is inserted into the subarachnoid space, so as to inject anesthetics into the subarachnoid space. After the injection of the anesthetic is completed, the anesthesia needle needs to be withdrawn, and then the epidural anesthesia catheter is inserted into the inner cavity of the epidural puncture needle, and is guided along the epidural puncture needle. The opening of the needle passes through, enter...
