Description
技术领域technical field
本实用新型涉及医疗设备器械，具体是一种穿刺导向麻醉注射器。The utility model relates to medical equipment, in particular to a puncture-guiding anesthesia syringe.
背景技术Background technique
麻醉(anesthesia)一词源于希腊语“an”及“aesthesis，”表示“知觉/感觉丧失”。感觉丧失可以是局部性的，即体现在身体的某个部位，也可以是全身性的，即体现为病人全身知觉丧失，无意识。从医学角度来讲，麻醉的含义是通过药物或其他方法使病人整体或局部暂时失去感觉，以达到无痛的目的，为手术治疗或者其它医疗检查治疗提供条件。麻醉可大致分为全身麻醉和局部麻醉两类。全身麻醉，便是常言道的“睡着状态”，病人意识消失，全身肌肉松弛，也不会体验到疼痛。局部麻醉，顾名思义，只是身体某些部位的麻醉。最常见的局部麻醉比如拔牙时，医生会先在你牙根附近注射一些局部麻醉药物，以免你感到疼痛。一般，局部麻醉还包括硬膜外麻醉或蛛网膜下腔麻醉(俗称“腰麻”)，也就是大家所熟称的“半身麻醉”。麻醉医生会在你后背中间进行一番操作，然后你便感觉到下半身被麻倒：你虽知道手术刀在切割，但不会感受到疼痛。The word anesthesia is derived from the Greek words "an" and "aesthesis," meaning "loss of consciousness/sensation." Loss of sensation can be localized, that is, reflected in a certain part of the body, or systemic, that is, manifested as a loss of consciousness throughout the patient's body and unconsciousness. From a medical point of view, the meaning of anesthesia is to temporarily lose the patient's overall or partial sensation through drugs or other methods, so as to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examination and treatment. Anesthesia can be roughly divided into general anesthesia and local anesthesia. General anesthesia is the so-called "sleep state" as the saying goes. The patient loses consciousness, the muscles of the whole body relax, and he will not experience pain. Local anesthesia, as the name suggests, is simply numbness of certain parts of the body. The most common local anesthesia, such as tooth extraction, the doctor will first inject some local anesthetic near the root of your tooth to prevent you from feeling pain. Generally, local anesthesia also includes epidural anesthesia or subarachnoid anesthesia (commonly known as "spinal anesthesia"), which is also known as "semi-body anesthesia". The anesthesiologist will do something in the middle of your back, and then you will feel the lower part of your body numb: you know the scalpel is cutting, but you don't feel the pain.
目前，患者在进行下腹部以下手术时，多采用腰麻或硬膜外麻醉，腰麻可获得良好的肉松弛，利于下腹部及盆腔手术，但麻醉时间受限，不能满足手术需求，而硬膜外麻醉可随时注入局麻药，延长麻醉时间，但其松弛程度较腰麻差，不利于盆腔手术操作。At present, patients usually use spinal anesthesia or epidural anesthesia when undergoing surgery below the lower abdomen. Epimembranous anesthesia can inject local anesthetic at any time to prolong the anesthesia time, but its degree of relaxation is worse than that of spinal anesthesia, which is not conducive to pelvic surgery.

请参阅图1～2，本实用新型实施例中，一种穿刺导向麻醉注射器，包括针头1、针头基座2、连接柄3、导向标4和注射器9；针头1为空心金属针，下段为斜面尖端，上端连接针头基座2，针头基座2上端连接注射器接口5，且注射器接口5与通用注射器9相匹配，针头基座2中部设有基座凹槽6，基座凹槽6与连接柄3的转动环7转动连接，连接柄3中部设有弧形凹陷8，弧形凹陷8用于容纳粗直径穿刺针外径，连接柄3竖直方向连接导向标4，导向标4上印有刻度，工作中，在血管或浆膜腔穿刺行局部麻醉的同时，通过针头1探查血管或浆膜腔位置，留置针头1、连接柄3及导向标4，用以指导粗直径穿刺针方向，根据诊疗常规判别穿刺点位置后，先以针头1在穿刺点皮肽注射形成皮丘，再负压下向深部进针，行皮下局部浸润麻醉，待麻醉范围达到穿刺要求后，以针头1对靶目标区域进行试探性穿刺，针头1尖端进入靶目标后，保留所述穿刺导向局麻针头，此时导向标4作为针头的延伸，与皮下的针头1保持均一的方向，并且可以通过连接柄3的转动环7适当调整导向标4的位置，再在导向标4的指示下，换用粗直径穿刺针通过连接柄3中部弧形凹陷8正式穿刺，待粗直径穿刺针进入靶目标内并送入导丝后，将粗直径穿刺针和针头1一并移除；所述注射器9下方为麻醉管12，麻醉管12呈圆筒状，麻醉管12中部连接有麻醉瓶13，麻药通过麻醉瓶13加入麻醉管12，并经过针头1流入患者体内的；所述麻醉管12内插装有调节杆14，调节杆14下端固设有与麻醉管12内壁滑动密封配合的密封塞15，其中，密封塞15底部形状与注射器9的底部形状相配合，工作中，通过转动调节杆14，驱动密封塞15沿麻醉管12内壁转动、下降；所述调节杆14的外壁设有螺纹17，麻醉管12最上端固设有固定块16，且固定块16中间的通孔上设有与螺纹17配合的内螺纹，其中，调节杆14上的螺纹17的长度略大于麻醉管12的长度，且麻醉管12的长度即为调节螺杆14的最大行程长度，因此，工作中，当驱动调节杆14转动时，调节杆14沿轴向旋进，同时驱动密封塞15向下旋进，因为麻醉管12通过麻醉瓶13灌入麻药，因此当密封塞15越过麻醉瓶13而进入麻醉管12下端时，密封塞15将会向麻醉管12前段内的麻药施加压力，提高了麻药的注射速度，加快了麻醉效果，当停止旋进密封塞15时，麻药的注射也就停止了，因此可以根据实际需要随时进行腰麻；所述麻醉管12最下端上连接有进气管11，进气管11上安装有进气阀10，通过操作进气阀10，控制进气管11的通断，当密封塞15旋进到进气管11位置时，如果还需要继续加注麻药，则将进气阀10打开，然后将密封塞15向上提升到麻醉瓶13上方，并关闭进气阀10，这样，麻酢管12前段又重新与麻醉瓶13联通，麻醉瓶13内的麻药就可以继续流进麻醉管12内，为了加快流入速度，可以继续向外旋出密封塞15，此时，麻醉管12内的气压会减小，会将麻醉瓶13内的麻药主动吸入麻醉管12内，当再次向麻醉管12前段旋进密封塞15时，就会重复上述过程；所述调节杆14外端固设有转盘18，转盘18上设有凸起杆19，在调节杆14外端设置转盘18，通过转动凸起杆19驱动转盘18的旋进、旋出，操作更方便，所述凸起杆19上方为球状，下方为圆柱体，凸起杆19与转盘18一体成型制造。Please refer to Fig. 1-2, in the embodiment of the utility model, a kind of puncture guiding anesthesia syringe comprises needle 1, needle base 2, connecting handle 3, guide mark 4 and syringe 9; Needle 1 is a hollow metal needle, and the lower section is Bevel tip, the upper end is connected to the needle base 2, the upper end of the needle base 2 is connected to the syringe interface 5, and the syringe interface 5 matches the universal syringe 9, the middle part of the needle base 2 is provided with a base groove 6, and the base groove 6 and The rotating ring 7 of the connecting handle 3 is rotatably connected, and the middle part of the connecting handle 3 is provided with an arc-shaped depression 8, which is used to accommodate the outer diameter of a thick-diameter puncture needle. The connecting handle 3 is vertically connected to the guide mark 4, and the guide mark 4 is Printed with scales, during work, while performing local anesthesia for blood vessel or serosa cavity puncture, probe the position of blood vessel or serosa cavity through needle 1, and indwell needle 1, connecting handle 3 and guide mark 4 to guide the large-diameter puncture needle After determining the location of the puncture point according to the routine diagnosis and treatment, first use needle 1 to inject skin peptide at the puncture point to form a skin mound, then insert the needle into the deep part under negative pressure, and perform subcutaneous local infiltration anesthesia. 1. Perform tentative puncture on the target area. After the tip of the needle 1 enters the target, keep the puncture guiding local anesthesia needle. At this time, the guide mark 4, as an extension of the needle, maintains a uniform direction with the subcutaneous needle 1 and can pass through The rotating ring 7 of the connecting handle 3 properly adjusts the position of the guide mark 4, and then under the instruction of the guide mark 4, use a thick-diameter puncture needle to pass through the arc-shaped depression 8 in the middle of the connecting handle 3 for formal puncture, and wait until the thick-diameter puncture needle enters the target After the guide wire is inserted into the guide wire, the large-diameter puncture needle and needle 1 are removed together; the anesthesia tube 12 is located below the syringe 9, and the anesthesia tube 12 is cylindrical, and the middle part of the anesthesia tube 12 is connected with an anesthesia bottle 13. The anesthesia tube 12 is added through the anesthesia bottle 13, and flows into the patient's body through the needle 1; the anesthesia tube 12 is inserted with an adjustment rod 14, and the lower end of the adjustment rod 14 is fixed with a sealing plug 15 that is sliding and sealingly matched with the inner wall of the anesthesia tube 12 , wherein, the shape of the bottom of the sealing plug 15 matches the shape of the bottom of the syringe 9.
