Abstract
The utility model discloses a novel epidural anesthesia needle, and aims to solve the technical problem that a conventional epidural anesthesia method is inconvenient to operate for anesthetists. The device structurally comprises a steel epidural anesthesia needle, wherein a plurality of crossed grooves are cut on the outer side wall of a needle point of the steel epidural anesthesia needle by using a laser cutting process.
Description
Technical field: this utility model relates to technical field of medical instruments, particularly novel epidural anesthesia pin.
Background technology: epidural anesthesia is a kind of anesthesia commonly used in the operation, but epidural anesthesia also has strict requirement to inserting needle.The key of judging the epidural puncture success now is to puncture spinal dura mater, so the lay special stress on needle point punctures the sensation of ligamenta flava, however this subjective sensation and unreliable.Even adopt disappear method, capillary negative pressure method etc. of some objective methods such as resistance also to allow the anaesthetist feel that operating process is complicated now.
Summary of the invention: the technical problems to be solved in the utility model is, makes novel epidural anesthesia pin, allows the anaesthetist feel unhandy problem to solve existing epidural anesthesia method.
The scheme that this utility model solves this technical problem is, novel epidural anesthesia pin is provided, and this apparatus structure comprises a steel epidural anesthesia pin, and the groove of many intersections is cut in the needle point lateral wall of this steel epidural anesthesia pin with laser cutting parameter.
During use, can under the guiding of high frequency ultrasound probe, carry out during the puncture of steel epidural anesthesia pin, because it is ultrasonic to different dieletric reflection differences, thereby the groove of many intersections of this utility model anesthetic needle needle point can be stronger than slick needle body reflexive, can make the position of many cross recesses in special epidural anesthesia pin needle point position on the screen of ultrasonic machine, show more clearly, to help ultrasonic doctor accurately to judge the position of needle point, therefore can under the guiding of high frequency ultrasound probe, puncture ligamenta flava and enter epidural space and do not pierce through spinal dura mater.
This utility model is simple in structure, novel in design, cost is low, be convenient to making.
Description of drawings: accompanying drawing is a structural representation of the present utility model
The specific embodiment:
Accompanying drawing has provided specific embodiment of the utility model, with reference to the accompanying drawings shown in, 1 is steel epidural anesthesia pin among the figure, the groove 2 of many intersections is cut in the needle point lateral wall of this steel epidural anesthesia pin 1 with laser cutting parameter.
Claims (1)
1. a novel epidural anesthesia pin is characterized in that it is a steel epidural anesthesia pin (1), and there is the groove (2) of many intersections the needle point lateral wall of this steel epidural anesthesia pin (1).
