神经丛刺激系统及神经丛刺激器Plexus Stimulation Systems and Plexus Stimulators

技术领域technical field

本实用新型涉及医疗器械领域，尤其涉及一种神经丛刺激系统及神经丛刺激器。 The utility model relates to the field of medical equipment, in particular to a nerve plexus stimulation system and a nerve plexus stimulator. the

背景技术Background technique

外周神经阻滞是很多外科手术的必需步骤，而准确定位神经丛的位置是阻滞手术成功的关键。传统的外周神经阻滞手术结合解剖图采用盲探法，即依赖医生的经验和患者对异感的反馈来判断注药针尖是否到达合适的位置。该方法难以准确定位神经丛，若患者处于昏迷或不配合时，该方法即无法实施。特别是患者若为肥胖患者，其体表由于堆积大量脂肪、体表解剖标志不明显，该方法效果即变得非常有限；又或者医生的经验不足，这种盲目试探的方法可能会对患者造成损伤。 Peripheral nerve block is a necessary step in many surgical operations, and accurate positioning of the nerve plexus is the key to successful block surgery. The traditional peripheral nerve block operation combined with anatomical diagrams adopts the blind detection method, which relies on the doctor's experience and the patient's feedback on the abnormal sensation to judge whether the injection needle tip has reached the appropriate position. This method is difficult to accurately locate the nerve plexus and cannot be performed if the patient is unconscious or uncooperative. Especially if the patient is obese, the effect of this method becomes very limited due to the accumulation of a large amount of fat on the body surface and the inconspicuous anatomical landmarks on the body surface; damage. the

可见，上述需要经过试探且难于量化的定位方法存在以下弊端：在试探过程中，若不慎将注药尖与神经直接接触，可能造成神经机械性损伤，给患者造成痛苦；若最终定位的位置离神经偏远，需要更大量的麻醉剂，不但造成浪费而且会对患者产生不良的副作用。因此，这种主观、难量化的定位方法对医生确定需要给患者多大的药量也提出了更大的挑战。若在手术过程中，因为没控制好药量导致患者在手术中醒来是件后果很严重的事。 It can be seen that the above-mentioned positioning method that needs to be tested and is difficult to quantify has the following disadvantages: during the testing process, if the injection tip is accidentally brought into direct contact with the nerve, it may cause mechanical damage to the nerve and cause pain to the patient; if the final positioning position Being remote from the nerve requires a larger amount of anesthetic, which is not only wasteful but also has adverse side effects on the patient. Therefore, this subjective and difficult-to-quantify positioning method also poses a greater challenge to doctors in determining how much medicine to give to patients. If the patient wakes up during the operation because the dosage of the drug is not well controlled, the consequences will be very serious. the
