Abstract

The utility model relates to a spring needle for extradural puncture, which is composed of a hollow needle core, a spring chamber and a needle tube. At the time of extradural cavity puncture, whether the extradural cavity puncture is successful or not can be accurately judged by operators according to movement situation of a cylinder body arranged in the spring chamber and whether the negative pressure appears or not in a water storage pipe. The utility model has the advantages of easy fabrication and convenient operation. The utility model is favorable for teaching.

Description

本发明属于医疗器械技术弹簧式硬膜外穿刺针是用于硬膜外腔麻醉的器械。 The present invention is a medical device art epidural needle is a spring-loaded device for epidural anesthesia. 目前,国内外所使用的硬膜外穿刺针(Tuohy民针),由针管和针芯组成。 At present, domestic use epidural needle (China a Tuohy needle), a needle and needle core composition. 其尖端锐利,容易穿破硬脊膜造成穿刺失败,而针芯只有支撑针管和防止软组织堵塞针管的作用,该针不具备能为操作者提供穿刺是否成功的标志。 Its sharp tip, puncture easily cause dural puncture failure, only the core needle support and needle cannula to prevent clogging of the role of the soft tissues of the needle, the needle does not have to provide puncture whether the sign of success for the operator. 判断穿刺成功与否,多凭操作者的经验与手感,临床常用的“黄韧带突破感”和负压试验,有时也不易判断,而引起麻醉失误时有发生。 Judgment puncture success, and more with the operator's experience and feel, commonly used in clinical "sense of the yellow ligament break" and the negative pressure test, and sometimes not easy to determine, caused by anesthesia errors have occurred.

本实用新型的目的旨在克服上述不足,提供一种即具有显示穿刺成功标志又不能穿破硬脊膜的弹簧式硬膜外穿刺针。 The purpose of the present invention is designed to overcome these shortcomings, namely a display to provide a successful puncture mark can not spring-loaded puncture the dura epidural needle.

新型是这样实现的:弹簧式硬膜外穿刺针由针管〔1〕,空心针芯〔2〕,弹簧室〔3〕,弹簧〔4〕,弹簧座〔5〕,弹簧盖〔6〕组成。 New is achieved: the epidural needle by the spring-loaded needle of [1], [2] a hollow core needle, the spring chamber [3], [4] the spring, the spring seat [5], [6] the composition of the spring cover. 空心针芯〔2〕尾部焊接一个园柱体〔7〕,园柱体〔7〕侧面钻一小孔〔8〕,小孔〔8〕上可插入贮水管〔9〕,空心针芯〔2〕尖端钻有两个对称性的通水孔〔10〕,通水孔〔10〕通过空心针芯〔2〕尾部的园柱体〔7〕与贮水管〔9〕相通。 [2] The hollow core needle cylinder of a solder tail portion [7] [7] The cylindrical body side drill a small hole (8), the reservoir can be inserted into the tube (9), the hollow core needle [2 [8] The orifice ] tip symmetry two drilled holes to water [10] [10] the water-passing hole through the hollow core needle cylinder of the tail [2] [7] [9] and the reservoir in communication pipe. 空心针芯〔2〕尾部的园柱体〔7〕留在弹簧室〔3〕内,在弹簧〔4〕的作用下与弹簧座〔5〕接触,位于弹簧室〔3〕中部。 [2] The hollow core needle cylinder of the rear stay in [7] [3] within the spring chamber, in contact with the spring seat of the spring [5] [4] In effect, the spring is located in the middle chamber [3]. 弹簧室〔3〕中部有两个对称的观察孔〔11〕,便于操作者观察园柱体〔7〕的移动情况和贮水管〔9〕内的负压现象。 [3] the middle of the spring chamber has two symmetrical viewing aperture [11], for the operator to observe the movement of cylindrical body and the negative pressure inside the reservoir tube phenomenon [9] [7]. 弹簧〔4〕插入弹簧座〔5〕内,一并装进弹簧室〔3〕中,由弹簧盖〔6〕固定,使空心针芯〔2与弹簧室〔3〕结合为一体,插入针管〔1〕内,弹簧室〔3〕的前端〔12〕与针管〔1〕尾部〔13〕衔接,空心针芯〔2〕尖部外露。 [4] the spring inserted into the spring seat [5], together put into the spring chamber [3], [6] by the spring cover is fixed and the hollow needle and the spring chamber of the core [2] [3 combined into one, the insertion needle [ 1], [3] the spring chamber [12] with the distal end of the needle tube tail of [1] [13] adapter, a hollow needle tip portion of the core [2] is exposed. 针管〔1〕尖端斜面为45°与空心针芯〔2〕尖部外露部分吻合良好。 [1] the needle tip with a 45 ° chamfer of the hollow core needle tip exposed [2] good fit portion. 在实施硬膜外腔穿刺的过程中,如果园柱体〔7〕向后移动,说明空心针芯〔2〕的尖部已触到黄韧带。 During epidural puncture in the embodiment, if the cylindrical body (7) moves backward, the tip of the hollow needle core described [2] has been touched ligamentum flavum. 此时可继续进针,当针管〔1〕的尖部穿透黄韧带时,观察孔〔11〕内的园柱体〔7〕迅速向前移动并同时产生负压现象,贮水管〔9〕内的液体被吸入腔内,此时操作者可判断硬膜外腔穿刺已告成功。 At this time, the needle can continue, when the tip of the needle cannula 1] [penetrating the ligamentum flavum, viewing aperture within the cylindrical body [11] to [7] quickly moves forward and simultaneously the phenomenon of negative pressure is generated, the reservoir tube (9) the liquid is sucked into the cavity, then the operator may determine epidural puncture has been successfully reported.
