The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly above and obliquely above the second feature, or simply meaning that the first feature is at a lesser level than the second feature.

Referring to fig. 1, an embodiment of a flow diverter for ophthalmic surgery is shown, wherein the flow diverter 1 includes a weight block 11, a hook 12 fixed on the top of the weight block 11, the hook 12 includes a connecting portion 121 connected to the weight block 11 and a hook portion 122 located at the end of the connecting portion 121, and the projection of the hook portion 122 in the vertical direction is located outside the projection of the weight block 11 in the vertical direction (in other embodiments, the projection of the hook portion 122 of the hook 12 in the vertical direction may also be within the projection of the weight block 11 in the vertical direction, and in this embodiment, the projection is preferably located outside the weight block 11, so as to facilitate the stability of the flow diverter 1 in hanging.

In this embodiment, the surface of the weight block 11 includes a near hook surface 111 close to the hook 12 and a far hook surface 112 far from the hook 12, and at least the surface roughness of the near hook surface 111 is smaller than that of the far hook surface 112. The connecting portion 121 is curved in a radian, and a projection of one end of the connecting portion 121, which is away from the weight block 11 and is connected with the hook portion 122, in a vertical direction is located outside the weight block 11.
