Abstract
The utility model provides an improved epidural puncturing needle, comprising an epidural puncturing needle, and an inner core needle. The top end of the pinhead of the inner core needle is a solid core; the needle cavity of the inner core needle is a hollow cavity; a drug outlet is arranged at the connecting position of the needle cavity of the inner core needle and the solid core. Two drug outlets are arranged at the outer circular arc point of the puncturing needle corresponding to the drug outlet of the inner core needle. The utility model has the advantages of simple structure, convenient operation, and exact anesthesia, and the advantages that the one-stitch three-point anesthesia is achieved, the puncturing needle is not needed to be rotated, and the spinal dura mater cannot be damaged.
Description
Technical field
This utility model relates to medical device technology, is specially a kind of anesthesia spinal needle that is applied in the improvement of epidural anesthesia.
Background technology
The existing dura mater that is used for is anaesthetized, when needing the Caudad dispensing, often adopt anesthesia spinal needle Rotate 180 degree, when operation technique, rotate anesthesia spinal needle and spinal dura mater might be scratched the danger that causes body spinal analgesia liquor-saturated, if the stage casing peridural anesthesia then can not rotate the dura mater puncture needle, two intervertebral spaces that often need to puncture are offerd medicine, otherwise easily cause the retardance plane narrower, do not reach the requirement of surgery anesthesia.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to operate, anesthesia accurately, reach 3 anesthesia of a pin, need not to rotate puncture needle, do not damage the anesthesia spinal needle of spinal dural improvement.
The purpose of this utility model is achieved through the following technical solutions: a kind of anesthesia spinal needle of improvement, it has anesthesia spinal needle, inner core pin, the needle tip of its inner core pin is real core, the pin chamber of inner core pin is a cavity, the pin chamber of inner core pin, the joint of real core are provided with medicine outlet, and the medicine outlet place of the corresponding inner core pin in the external arc place of puncture needle is provided with 2 medicine outlets.2 medicine outlets on the puncture needle corresponding with medicine outlet on the inner core pin are vertically to arrange.Described puncture needle also can be beveled, and 2 medicine outlets on the beveled puncture needle also can vertically be located at the back side on puncture needle inclined-plane.
The beneficial effects of the utility model are: when anesthesia spinal needle and nook closing member during at epidural puncture success back water filling or gas injection non-resistance, medicinal liquid injects epidural space smoothly by the medicine outlet of interior nook closing member 2 vertical medicine outlets by anesthesia spinal needle, realize the anesthesia task, have 3 anesthesia of a pin, need not to rotate puncture needle, easy to operate, anaesthetize advantage accurately.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The anesthesia spinal needle of a kind of improvement of the present utility model, it has anesthesia spinal needle 1, inner core pin 2, the needle tip of its inner core pin 2 has real core 6, the pin chamber 7 of inner core pin 2 is a cavity, the pin chamber 7 of inner core pin 2, the joint of real core 6 are provided with medicine outlet 3, and medicine outlet 3 places of the corresponding inner core pin in the external arc place of puncture needle 1 (2) are provided with 2 medicine outlets 4,5.2 medicine outlets 4,5 on the corresponding puncture needle 1 of medicine outlet 3 on described and the inner core pin 2 are vertically to arrange.The syringe needle of puncture needle 1 also can be beveled, and 2 medicine outlets 4,5 on beveled puncture needle 1 needle point also can vertically be located at the back side of inclined-plane puncture needle 1.During use, after epidural puncture success, medicinal liquid injects epidural spacies smoothly by the medicine outlet 3 of interior nook closing member 22 vertical medicine outlets 4,5 by anesthesia spinal needle, realizes the task of anesthesia; Again inner core pin 2 is extracted, put routinely and manage fixing getting final product.Because the needle tip of inner core pin 2 of the present utility model is real core 6, pin chamber 7 is a cavity, real core 6 can seal inner core pin 2 front ends when puncture needle 1 puncture, so need not change nook closing member after puncturing successfully, get final product liquid medicine injection, simplify operation sequence, can not wear out spinal meninges again, safe in utilization, simple in structure.This utility model is not described part in detail and is known technology.
