Description
Technical Field
The utility model relates to the technical field of medical simulation teaching appliances, in particular to a peripheral nerve block virtual simulation training system under ultrasonic guidance.
Background
Peripheral nerve block refers to injecting local anesthetic around peripheral nerve trunk, plexus and node, and blocking impulse conduction, so as to generate anesthetic effect in the dominated region. The peripheral nerve block can obtain a larger anesthetic region by only injecting one part, and has the advantages of small influence on the organism, reduction of postoperative pain and the like. However, peripheral nerve blocking has certain requirements on the operation technology, the blocking effect is incomplete easily caused by inaccurate puncture position, and serious complications such as local anesthetic poisoning, nerve injury and the like can be even caused by improper operation. Therefore, the operation must be familiar with the local anatomy, and the tissue through which the puncture needle passes, and the blood vessels, organs, body cavities, and the like in the vicinity thereof, must be known. Common nerve blocks include cervical plexus, brachial plexus, paraspinal nerve, ventral fascia plane, lumbar plexus, femoral nerve and sciatic nerve blocks.
The armpit brachial plexus nerve block is commonly used for the postoperative and postoperative analgesia of forearm operation, and the nerve block under anatomical location by the armpit artery only has the condition of wrong blood vessel entering or insufficient blocking. With the development of technology, anesthesiologists gradually begin to guide nerve block anesthesia by ultrasound, and the ultrasound guidance makes the process simple, so that the effect and safety of nerve block are greatly improved. However, for anesthesiologists or pain department beginners, the learning of ultrasound techniques requires a certain experience accumulation, and guiding nerve block under ultrasound is more necessary to constantly learn and practice. Besides the most fundamental anatomical knowledge, the method also comprises the use of an ultrasonic probe, the positioning of an anatomical structure under ultrasound, the positioning of a puncture needle, the knowledge of a puncture access and the like. Because of limitations in safety, ethics, willingness of patients, and the like, training on a real person is not feasible, so the learning of peripheral nerve block at the present stage generally mainly comprises the following three forms:
technique 1: the real person practice study is adopted, only the anatomical structure is observed, and the actual puncturing operation is not carried out;
technique 2: the nerve block training simulator (mainly an brachial plexus) is characterized in that the model is an upper body of an adult, a supine head is taken to be in a low position, a right shoulder is lifted up, and the head is deviated to the opposite side, so that the upper fossa of the collarbone is exposed. Body surface markers obviously include sternal notch, sternocleidomastoid muscle, collarbone and rib. Training for brachial plexus block anesthesia can be performed using the intersymbol method. If three inter-muscular ditch arm plexus nerves are touched in the puncturing process, the indicator lamp of the monitor is correspondingly lightened.
Technique 3: animal models, such as pork streaky pork, may be used to perform ultrasound-guided lower abdominal transverse fascia plane retardation.
The above-described prior training techniques 1-3 all have significant drawbacks: in the technology 1, the anatomical positioning under the ultrasound can be generally performed, the puncture needle positioning and the puncture path training can not be performed, and the mutual coordination and matching of the ultrasonic probe and the puncture needle can not be particularly trained; the technology 2 can only carry out blind wearing exercise of a single part, has low cost and poor reality, and can not carry out ultrasonic exercise; although the technique 3 is more realistic, it can only exercise the abdominal transverse fascia arrest (TAP) under ultrasound guidance, and cannot perform other important sites such as brachial plexus, ilium fascia, cervical plexus, and paraspinal nerve block.
