The utility model relates to the technical field of clinical anaesthesia equipment, in particular a new local anaesthesia needle, which includes a three pipe, a T shaped bar, a U shaped connection head, a adjusting knob and a puncture needle. The upper end interface of the three pipe is sleeved on the cylinder neck of the syringe, and the joints of the left and right sides of the three pipe are sleeved with a connecting hose and the lower end of the three pipe is provided at the lower end of the tube. T shaped rod, the lower end of the T shaped bar has a U shaped connection head, the lower end of the U shaped connection head is provided with two rotating sleeves, the rotating sleeve has a rotating shaft, a adjusting knob is provided on the rotating shaft between the rotating sleeve, and the left and right ends of the rotating shaft are provided with a threaded rod, and the screw rods on both sides are symmetrically connected with a knuckle nut. The structure of the utility model is reasonable and can be punctured on both sides of the anaesthetized part at the same time. It can accurately adjust the distance between the needles on both sides of the needle, and can lock the adjusting knob to prevent the misoperation. It is simple and convenient to use, save time and labor, and reduce the work difficulty of the medical staff.
【技术实现步骤摘要】
一种新型局部麻醉针头
本技术涉及临床麻醉用具
,尤其是一种新型局部麻醉针头。
技术介绍
局部麻醉也称部位麻醉,是指在患者神志清醒状态下,将局麻药应用于身体局部,使机体某一部分的感觉神经传导功能暂时被阻断,运动神经传导保持完好或同时有程度不等的被阻滞状态。所以麻醉是手术能顺利进行的必要条件,麻醉的好坏、麻醉的时间长短直接影响手术的进行,目前临床上在给患者进行体表肿瘤组织切除时,需要用注射器抽取麻醉药物后,绕肿瘤一周进行多次穿刺麻醉,这样操作十分麻烦、费时费力,给病人增加了痛苦,同时给医务人员增加了工作难度。
技术实现思路
本技术的目的是为了克服上述技术缺点提供一种新型局部麻醉针头,精确调节两侧穿刺针头之间的间距,可锁定调节旋钮防止误操作,使用简单方便,省时省力。本技术解决技术问题采用的技术方案为:一种新型局部麻醉针头,包括三通管、T形杆、U形连接头、调节旋钮、穿刺针头,所述三通管上端接口套接在注射器的筒颈上,三通管左右两侧接口均套接有连接软管,三通管下端设有T形杆,T形杆下端设有U形连接头,U形连接头下端设有两个转动套筒,转动套筒内套有转轴,转动套筒之间的转轴上设有调节旋钮,转轴的左右两端均设有螺纹杆,左右两侧螺纹杆的螺纹方向相反,两侧螺纹杆的端部均螺接有端盖,两侧的螺纹杆上对称螺接有调节螺母,调节螺母外侧设有与其垂直的固定套筒,所述T形杆的横杆上设有刻度线,T形杆的横杆上对称套有两个滑动套筒,滑动套筒外侧设有与其垂直的固定套筒,同侧的T形杆与螺纹杆的固定套筒内通过固定螺栓固定有连接硬管,连接硬管上端套接有连接软管,连接硬管下端套接有穿刺针头。本装置使用时 ...
