发明名称：一种神经阻滞麻醉针、麻醉装置及其使用方法。Invention name: A nerve block anesthesia needle, an anesthesia device and a method of using the same.

技术领域technical field

本发明涉及医疗器械技术领域，尤其涉及一种神经阻滞麻醉装置的使用方法。The invention relates to the technical field of medical devices, in particular to a method for using a nerve block anesthesia device.

背景技术Background technique

神经阻滞麻醉是将局麻药注射至外周神经干附近，通过阻断神经冲动的传导，使将神经所支配的区域麻醉。在神经干、丛、节的周围注射局麻药，阻滞其冲动传导，使所支配的区域产生麻醉作用，称神经阻滞.神经阻滞只需注射一处，即可获得较大的麻醉区域.但有引起严重并发症的可能，故操作时必须熟悉局部解剖，了解穿刺针所要经过的组织，以及附近的血管、脏器和体腔等.常用神经阻滞有助间、眶下、坐骨、指(趾)神经干阻滞，颈丛、臂神经丛阻滞，以及诊疗用的星状神经节和腰交感神经节阻滞等。Nerve block anesthesia is the injection of local anesthetics near the peripheral nerve trunk to block the conduction of nerve impulses to anesthetize the area innervated by the nerve. Local anesthetic is injected around the nerve trunk, plexus, and ganglion to block its impulse conduction and make the innervated area anesthetize. .But there is the possibility of serious complications, so you must be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, as well as the nearby blood vessels, organs and body cavities. Finger (toe) nerve trunk block, cervical plexus, brachial plexus block, as well as stellate ganglion and lumbar sympathetic ganglion block for diagnosis and treatment.

麻药注射时，在合适的位置向后、内、下方向推进，当病人诉有放射到手指、腕或前臂的异感时即停止前进，回抽如无血或空气，即注入药液。因此，麻药注射时，还需回抽很重要，能够有效避免穿刺不当，造成的并发症。When the anesthetic is injected, it is advanced backward, inward and downward at a suitable position. When the patient complains of an abnormal sensation radiating to the fingers, wrist or forearm, it will stop moving forward. If there is no blood or air, the drug will be injected. Therefore, when the anesthetic is injected, it is very important to withdraw, which can effectively avoid complications caused by improper puncture.

目前，现用的麻醉针如专利公告号CN106581820A公示的一种多药物注射用改进型麻醉针，只在如何实现一次注射多种药物方面做改进；又如专利公告号CN108355202A公示的一种便携式麻醉针，只在便携方便上做改进；又如专利公告号CN109223054A公示的一种带定位架的骨髓穿刺抽取装置，其用于解决减少穿刺次数的问题，还配有定位架，方便医务人员进行穿刺以及骨髓液抽取操作；等等还有其他的麻醉针均用于解决注射量把控方面的问题。这些现用的麻醉针均不具备在回抽上的提醒功能，一旦进针位置不对，不回抽查看是否穿入动脉或静脉中，则会出现因穿刺不当引起的一系列的并发症状，给患者带来痛苦。At present, the currently used anesthesia needles, such as an improved anesthesia needle for multi-drug injection disclosed in Patent Publication No. CN106581820A, are only improved in how to inject multiple drugs at one time; another example is a portable anesthesia needle disclosed in Patent Publication No. CN108355202A The needle is only improved in terms of portability and convenience; another example is a bone marrow puncture extraction device with a positioning frame disclosed in Patent Bulletin No. CN109223054A, which is used to solve the problem of reducing the number of punctures, and is also equipped with a positioning frame, which is convenient for medical personnel to perform puncture And bone marrow fluid extraction; etc. and other anesthesia needles are used to solve the problem of injection volume control. These current anesthesia needles do not have the reminder function on withdrawal. Once the needle is inserted in the wrong position, if the needle is not withdrawn to check whether it penetrates into the artery or vein, a series of complications will occur due to improper puncture. Pain for the patient.

One end of theballoon 51 away from thesecond suction cup 52 is connected to thesupport plate 3 . Theballoon 51 is connected to thesupport plate 3 through adrawstring 55, and the drawstring can be an elastic drawstring, and it is necessary to ensure that the adsorbent 5 has a sufficient length for use.

本发明还提供一种神经阻滞麻醉装置的使用方法，包括：The present invention also provides a method for using the nerve block anesthesia device, comprising:

S1、将所述神经阻滞麻醉装置置于使用者旁侧合适位置，通过所述压板2将整个装置固定，要么采用粘贴，要么采用身体压实。S1. The nerve block anesthesia device is placed at a suitable position beside the user, and the entire device is fixed by thepressing plate 2, either by sticking or by body compaction.

S2、将麻醉针1套装在所述角度调节组件4的安装管中，且使麻醉针1上的滑块153与所述安装管43内的滑槽431配合，且在出液孔处安装针体12。S2. Set theanesthesia needle 1 in the installation tube of theangle adjustment assembly 4, make theslider 153 on theanesthesia needle 1 fit with thechute 431 in theinstallation tube 43, and install the needle at the liquidoutlet hole body 12.

S3、旋转调节手柄，以调节麻醉针至合适角度。一般，麻醉针1与目标位置成60°角。S3. Rotate the adjustment handle to adjust the anesthesia needle to an appropriate angle. Typically, theanesthesia needle 1 is at a 60° angle to the target location.

S4、角度调节完成后，将半齿圈42向支板3的方向推进，使第一吸盘45与支板3接触并吸附，以固定半齿圈42、安装管43及麻醉针1的角度。S4. After the angle adjustment is completed, push thehalf ring gear 42 in the direction of thesupport plate 3 to make thefirst suction cup 45 contact and absorb thesupport plate 3 to fix the angle of thehalf ring gear 42 , theinstallation tube 43 and theanesthesia needle 1 .

S5、将吸附件5的硬环53贴附于目标位置的旁侧，同时挤瘪球囊并松开，球囊产生负压使硬环与目标位置的旁侧紧密贴合；拉动吸附件，使目标位置隆起。S5. Attach thehard ring 53 of the adsorption member 5 to the side of the target position, squeeze and release the balloon at the same time, and the balloon generates negative pressure to make the hard ring closely fit the side of the target position; pull the adsorption member, Raise the target location.

S6、在隆起的合适位置进针，进针的同时限位组件15上的滑块153在安装管43中的滑槽431内滑动。到达合适深度后（针尖进入1~2cm深度），推进麻醉针的活塞芯杆13。进针需要缓慢，一般情况下，还需将针退回2mm。在所述限位组件15上设置挡板152，也起到了避免进针过深的限位作用。S6. Insert the needle at the proper position of the bulge, and at the same time the needle is inserted, theslider 153 on the limitingassembly 15 slides in thechute 431 in theinstallation tube 43 . After reaching the appropriate depth (the needle tip enters the depth of 1-2 cm), advance thepiston core rod 13 of the anesthesia needle. Needle insertion needs to be slow, and under normal circumstances, the needle needs to be retracted by 2mm. Abaffle plate 152 is provided on the limitingassembly 15, which also plays a limiting role to prevent the needle from being pushed too deeply.

S7、当活塞芯杆13与折臂141的第二臂1412初次接触时，因支持囊体142的作用，产生一个阻力，此时，操作者手感后，需将活塞芯杆13抽出一段距离。所述折臂141在活塞芯杆13的初次推力作用下转动并撕破封条1421，使支持囊体142撕开一个用于排气的口，通过该口将支持囊体142中的气体排出。S7. When thepiston core rod 13 contacts thesecond arm 1412 of thefolding arm 141 for the first time, a resistance is generated due to the function of thesupport bag 142. At this time, the operator needs to pull out thepiston core rod 13 for a certain distance after feeling it. Thefolding arm 141 rotates and tears theseal 1421 under the action of the primary thrust of thepiston core rod 13, so that thesupport bag 142 is torn open for an exhaust port, and the gas in thesupport bag 142 is discharged through the port.

S8、此时，拉簧143产生的拉力克服支持囊体142的支撑力，将折臂141延伸至腔体111内的部分（第二臂1412）拉回至槽口112中。S8. At this time, the pulling force generated by thetension spring 143 overcomes the supporting force of thesupport bag 142, and pulls the part of thefolding arm 141 extending into the cavity 111 (the second arm 1412) back into theslot 112.

S9、在步骤S7中回抽活塞芯杆时没有异常（异常指抽出血液），则再次推进活塞芯杆13，将麻药自出液孔推出至组织内。如抽出有异常，则需退针重新调整位置。S9. In step S7, there is no abnormality when the piston core rod is withdrawn (abnormality refers to drawing out blood), then push thepiston core rod 13 again to push the anesthetic into the tissue from the liquid outlet hole. If there is any abnormality in the extraction, it is necessary to withdraw the needle and re-adjust the position.

如需重新调整角度时，则通过拉手46将半齿圈42抽出，使其上的第一吸盘45与支板3脱离，再重新通过转动调节手柄44，将麻醉针调节至合适的角度位置并固定，再按上述步骤进针。When the angle needs to be readjusted, thehalf ring gear 42 is pulled out through the handle 46 to disengage thefirst suction cup 45 from thesupport plate 3, and then the adjustment handle 44 is rotated again to adjust the anesthesia needle to a suitable angle position and Fix, and then follow the above steps to insert the needle.

S10、麻醉注射完成后，将麻醉针1自安装管43中滑出，并将吸附件5的阀门54打开，释放负压。S10. After the anesthesia injection is completed, slide theanesthesia needle 1 out of theinstallation tube 43, and open thevalve 54 of the adsorption member 5 to release the negative pressure.
