具体实施方式 Detailed ways

[0011] 下面结合附图及实施例对本发明的技术方案做进一步详细的说明。 [0011] Example embodiments further detailed description of the technical solution of the present invention and the accompanying drawings below.

[0012] 如图1所示,一种多功能眼科用冲洗针,包括针柄1、针头4、连接套3和冲洗管2,针柄I和针头4均为空心结构,针柄I的一端用于和医用注射器连接,针柄I的另一端与连接套3的一端通过螺纹旋接,连接套3的另一端与针头4 一端铰接,所述冲洗管2依次穿设于针柄1、连接套和3针头4内部。 [0012] As shown in FIG 1, a multifunction ophthalmic irrigation needle including a needle handle, the needle 4, and a flush pipe connecting sleeve 3 2, needle shaft and the needle 4 are I hollow structure, the shank end of the needle I of used medical syringe and is connected to the other end of the needle shank and I 3 by connecting one end of the threaded sleeve is screwed, hinged at one end 4 connected to the other end of the needle hub 3, 2 successively through the irrigation tube disposed in the needle shank 1, is connected 3 and 4 inside the needle sleeve.

[0013] 连接套3的另一端和针头的一端分别设有U型卡,两U型卡的相对应侧卡板之间铰接。 End of [0013] the other end of the connection sleeve and the needle 3 are respectively provided with a U-type card, the card between the side plate corresponding to the two U-shaped hinge card.

[0014] 连接套3与针头4的铰接处设置有用于限制针头在连接套上转动角度的锁紧机构;当针头转动一定角度后,通过锁紧机构将针头与连接套之间的铰接处锁紧,保证手术过程中针头不会转动。 [0014] The connecting sleeve 3 is provided with the needle 4 at the hinge for restricting the needle sleeve connected to the locking mechanism of the rotation angle; when the needle is rotated a predetermined angle by the locking mechanism locks the hinged connection between the needle and the sleeve tight to ensure that the needle does not rotate during operation.
