Preferably, the elastic capsule 3 is a spherical capsule body or a folded capsule body folded in a wave shape. Preferably, the outer wall of the outer sleeve 1 is evenly distributed with anti-slip patterns 15, which can increase friction and make the operator more stable when holding it.

[0022] In actual operation, in order to efficiently expand the lacrimal puncta, the lacrimal punctum dilator needs to be gently rotated after insertion. In this embodiment, the cross-section of the outer sleeve 1 is designed to be square, and two rotation notches 9 are relatively provided on the top of the outer sleeve 1. The connecting part of the elastic bag 3 and the flushing tube 4 is fixed with a rotating sleeve 10, and the rotating sleeve 10 is rotatably installed at the notch 9 on the top of the outer sleeve 1. By operating the rotating sleeve 10 to rotate slowly, the entire flushing assembly and the lacrimal punctum dilator head 7 below can be controlled to rotate, thereby slowly expanding the lacrimal puncta.

[0023] The amount of saline used in lacrimal duct irrigation is not much, and the operator needs to be able to visually see the volume of the liquid to be used for irrigation. In this embodiment, the tube body of the outer sleeve 1 can be designed as a transparent plastic part to directly observe the injection of liquid into the internal irrigation component. Alternatively, as another design method, a transparent window 11 extending linearly along the length extension direction of the outer sleeve 1 can also be provided on the side wall of the outer sleeve 1. Accordingly, in this embodiment, the irrigation tube 4 is also designed as a transparent tube, and the outer wall of the irrigation tube 4 is provided with scale lines from top to bottom for reflecting the internal liquid volume, so as to accurately grasp the volume of the injected saline.

[0025] According to an example of the utility model, a suction cup 14 is connected to the side wall of the outer sleeve 1 through a connecting rod 13, and the connecting rod 13 is a metal rod that can be bent and shaped at will. The suction cup 14 is an elastic silicone or rubber suction cup with good skin-friendliness. Before use, the suction cup 14 can be pressed and adsorbed on the patient's cheek, which can help stabilize the entire device and reduce damage to the patient's eyes due to shaking of the patient or unstable hands of the operator.
