[0018] Figure 2 This is a schematic structural diagram of the utility model of the drainage device for ophthalmic surgery from another perspective. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings. Example 1

[0020] like Figure 1 and Figure 2 The ophthalmic surgical drainage device shown mainly comprises a counterweight body 1, a hook assembly 2, a flushing and suction assembly 3 and other structures.

[0021] The counterweight 1 may be conventional, for example, the counterweight 1 has a thin end 11 and a thick end 12 arranged opposite to each other, so that the distance between the center of gravity of the counterweight 1 and the thin end 11 is greater than the distance between the center of gravity of the counterweight 1 and the thick end 12 (i.e., the center of gravity of the counterweight 1 is offset). In this embodiment, the shape of the counterweight 1 is preferably a water drop shape.

[0022] The hook assembly 2 is connected to the counterweight body 1, and includes a hook 21 and a connecting rod 22. The hook 21 is arranged on one side of the thin head end 11, and is used to hook at the corner of the patient's eye. The connecting rod 22 is one or two (preferably two to ensure the strength of the entire hook assembly 2), which are connected to the hook 21 (usually integrally connected) and connected to the thin head end 11; that is, one end of the connecting rod 22 is connected to the thin head end 11 of the counterweight body 1 and the other end is integrally connected to the hook 21.

[0023] The flushing and suction assembly 3 mainly includes a transfer tube 31 and a hollow tube group 33. The hollow tube group 33 is formed on the connecting rod 22 and is away from the hook 21, that is, the hollow tube group 33 and the hook 21 (mainly the everted hook part) are located on both sides of the connecting rod 22; the transfer tube 31 is connected to the end of the hollow tube group 33 (the end away from the hook 21), so that part of the structure of the transfer tube 31 is tilted away from the counterweight body 1 (at this time, the transfer tube 31 corresponds to the position of the counterweight body 1), so as to avoid the counterweight body 1 from having an adverse effect on the function of the flushing and suction assembly 3. There are multiple liquid outlets (not shown in the figure), which are opened at the end of the hollow tube group 33 located at the hook 21. At this time, when the hook 21 is hooked at the corner of the patient's eye, the flushing liquid can be input into the eye through the liquid outlet to keep the cornea in a moist state to avoid corneal necrosis, or to absorb the effusion in the eye.

[0024] In this embodiment, the flushing and suction component 3 also includes a guide tube 32 connected to the transfer tube 31, through which the flushing and suction component 3 can be connected to an external flushing device or a liquid pumping device, which can be automatic or manual according to actual needs.

[0025] In this embodiment, the hollow tube group 33 includes a first hollow tube 331 formed on two connecting rods 22 respectively and a second hollow tube 332 connecting the ends of the two first hollow tubes 331 and corresponding to the hook 21, and the transfer tube 31 is connected to the other ends of the two first hollow tubes 331; at this time, a plurality of liquid outlets are opened on the second hollow tube 332, which is beneficial to improve the strength of the entire hook assembly 2, and can also realize the input of flushing fluid or absorption of accumulated fluid in the patient's eyes, playing a dual role. Example 2

[0026] This embodiment provides a drainage device for ophthalmic surgery, which is basically the same as that in Embodiment 1, except that: the hook 21 is hollow, and the hollow tube group 33 is connected to the hook 21. Specifically, the hook 21 and the connecting rod 22 are hollow independently and connected to each other, and the first hollow tube 331 is connected to the connecting rod 22 (at this time, part of the structure of the first hollow tube 331 is connected to the connecting rod 22), and multiple liquid outlets are provided on the hook 21, so that flushing liquid can be input to the connecting rod 22 and the hook 21 through the first hollow tube 331 or the accumulated liquid can be sucked out.
