[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of this utility model. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this utility model, but are only for illustrating the essential spirit of the technical solution of this utility model.

[0021] like Figure 1 As shown. This utility model provides an external scleral depressor for ophthalmic surgery, including a handle 1. One end of the handle 1 is provided with a depressor part, and the depressor part has at least two elastic depressor strips 2. One end of the elastic depressor strips 2 is spaced apart from each other, and the other end of the elastic depressor strips 2 is integral. A sliding sleeve 3 is sleeved on the outer periphery of the handle 1. The sliding sleeve 3 slides along the handle axis to drive the opening and closing of the elastic depressor strips 2.

[0022] Specifically, in this invention, the top pressing part consists of three elastic pressure strips 2, one end of which is spaced apart and extends outward. The elastic pressure strips 3 are made of elastic metal material. The sliding sleeve 3 forms a damped sliding connection with the handle 1. When the hand holds the handle 1, the fingers can push the sliding sleeve 3 to move axially along the handle 1. When the end of the sliding sleeve 3 moves forward, the sliding sleeve 3 gradually squeezes one end of the elastic pressure strip 2 inward and gradually merges them into one, so that the outer ends of the elastic pressure strip 2 gradually merge from a separated state into one.

[0023] Furthermore, the sliding sleeve 3 is a stepped sleeve with a small opening at one end and a large opening at the other end. The end with the large opening is fitted around the outer periphery of the handle end on the side closest to the top pressing part. When the sliding sleeve 3 moves along the handle 1, it drives the elastic pressure strip 2 to open and close through the end with the large opening.

[0024] Of course, as a preferred option, the number of elastic strips 3 is not limited to three, but at least two.

[0025] Furthermore, to better press on the eyeball and improve pressure comfort, each elastic pressure strip has a pressure surface at its outer end. The outer periphery of the pressure surface is curved to enhance eye comfort.

[0026] Furthermore, in order to facilitate the insertion of the pressure-receiving part into the gap between the eyeball and the soft tissue inside the orbit, the pressure-receiving surface is distributed along an arc-shaped array. After the arc-shaped array is distributed, the pressure-receiving surface basically matches the surface shape of the eyeball, which not only satisfies the requirement of inserting into the gap to press on the eyeball, but also further improves the comfort of pressure.

[0027] Furthermore, in order to better prevent the top pressing part from sliding, a friction body 201 is provided on the top pressing surface. The friction body 201 can better enhance the friction between the top pressing part and the eyeball, and prevent the top pressing surface from sliding when pressing the eyeball.

[0028] like Figure 2 As shown. Further, the friction body 201 is an array of stripes spaced apart, with stripes 2011 sequentially spaced along the axial direction of the elastic pressure strip 2. The stripes 2011 can axially surround the end of the elastic pressure strip 2. The stripes 2011 are raised strips with smooth arcuate surfaces.

[0029] like Figure 3 As shown. Of course, as a preferred option, the stripes 2011 can also be arranged at radial intervals along the elastic strip 2, in which case the stripes 2011 can surround the radial outer periphery of the elastic strip 2.

[0030] like Figure 4 As shown. Further, as a preferred embodiment, the friction body 201 consists of a plurality of protrusions 2012 spaced apart. The protrusions 2012 are evenly distributed at the ends of the elastic pressure strip, and the outer periphery of the protrusions 2012 is a smooth arc surface.

[0031] Furthermore, as a preferred option, the friction body 201 can also have a knurled pattern.

[0032] Furthermore, to better control the opening and closing degree of the pressure section, the sliding sleeve 3 is damped and slidably connected to the handle 1. This allows the opening and closing state of the elastic pressure strip 2 to be controlled by the movement distance of the sliding sleeve 3 during the contraction process, so that the size of the unfolded area of ​​the elastic pressure strip 2 can meet the different pressure requirements of the sclera position.

[0033] Furthermore, in order to prevent the sliding sleeve 3 from sliding too fast, several damping rings are provided between the sliding sleeve 3 and the handle 1. The damping rings can increase the friction between the sliding sleeve 3 and the handle 1.

[0034] Furthermore, a scale line 101 is provided on the outer periphery of one end of the handle 1. When the sliding sleeve 3 slides along the handle 1, the sliding distance can be identified by the scale line 101. In this way, the position of the scale line 101 can be used to make the pressing part open and close according to a certain size.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
