Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-angle regulator for a nerve blocking needle. Background Art

[0002] Nerve block is the process of injecting local anesthetic around nerve trunks, plexuses, and ganglia to block the conduction of impulses and produce an anesthetic effect in the area controlled. This is called nerve block. Nerve block only requires one injection to obtain a larger anesthesia area. In order to ensure the stability of the injection needle puncture, an adjustable bracket is required for support and guidance.

[0003] After searching, the utility model with announcement number CN219070551U provides a nerve block needle puncture locator, which can fix the puncture needle by setting a strap and an arc plate, solving the problem that most of the existing puncture methods are manual puncture. This puncture method cannot adjust the position and fix the nerve block needle, which makes it easy to shake during puncture, making it impossible to reach the predetermined puncture position, which brings troubles to the actual operation of medical staff.

[0004] The locator has the following disadvantages during use: it is fixed by a strap during use, but after fixation, the angle of the injection needle is not convenient to adjust, and the position of the locator needs to be constantly adjusted, which makes puncture more time-consuming, and the injection needle needs to be released during the puncture process. After release, the injection needle will shake, making it inconvenient for precise guidance. Utility Model Content
