Abstract

The invention discloses a novel nerve block needle which comprises a needle cylinder assembly, a needle body is movably connected to the bottom of the needle cylinder assembly, a micro-current detector surrounds the tail end of the needle body, a through hole is formed in one side of the top of the needle cylinder assembly, and a connecting hose connected with the needle body penetrates through the interior of the through hole. A connector connected with the micro-current detector is installed on one side of the outer wall of the needle cylinder assembly, the connector is connected with a signal amplifier through a data line, and the signal amplifier is connected with a computer through a data line. The needle is novel in structure and ingenious in conception, the judgment accuracy of medical staff can be effectively improved, errors of injection parts can be avoided, and the use safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a novel nerve block needle. Background technique [0002] Inject local anesthetics around nerve trunks, plexuses, and nodes to block their impulse conduction and anesthetize the innervated area, which is called nerve block. Nerve blocks require only one injection to obtain a larger area of ​​anesthesia. However, it may cause serious complications. Therefore, it is necessary to be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, and the nearby blood vessels, organs, and body cavities. Commonly used nerve blocks include block of interstitial, infraorbital, sciatic, and digital (toe) nerve trunks, cervical plexus, brachial plexus block, and stellate ganglion and lumbar sympathetic ganglion blocks for diagnosis and treatment. [0003] Peripheral nerve block is a commonly used anesthesia method in clinical practice. It is w...
