Visual nerve blocking and positioning guide instrument

Abstract

The visualized nerve block location guidance instrument is mainly composed of a host, a monitor, a B-ultrasound probe, a nerve plexus stimulating needle, a nerve detection pen and an electromagnetic space tracking transmitter. The host is composed of an industrial computer module, a B-ultrasound module, an electromagnetic positioning and tracking function module and The nerve stimulation pulse module is composed. The invention combines the direct visibility of the ultrasonic diagnostic instrument with the accuracy and precision of the nerve plexus stimulation pulse, which facilitates the operation of the anesthetist, reduces the complexity of the operator and the operation of the instrument, and also reduces the use of anesthetics. side effects on patients; greatly improved the accuracy and safety of nerve plexus positioning and blocking; at the same time, the functional modules of the nerve plexus stimulator circuit and the space tracking and positioning system are connected to the host machine through the software management and access data communication interface. The connection realizes the purpose of planning in advance, direct vision operation, objective evaluation, safety and security in puncture surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visual nerve block positioning guide. Background technique [0002] Surgical treatment of the trunk, limbs and neck of the human body due to pain or trauma is one of the most commonly used methods in clinical medicine, and these surgical treatments require nerve blockade of the peripheral nerves of the human body - commonly known as Anesthesia, it is a necessary condition before surgery. The necessary condition for the success of peripheral nerve block is to correctly locate the position of peripheral nerve plexus in human tissue and inject anesthesia drugs. Currently, there are several methods for positioning peripheral nerve plexus clinically: [0003] a. Nerve plexus block under the guidance of nerve plexus stimulator: This is one of the methods that have been developed and promoted clinically in recent years. When it works, the nerve plexus stimulator generates 1-2...
