[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the utility model:

[0019] Reference Figure 1-3 The adjustable squint hook comprises a handle 1, the handle 1 is 80 mm long, a connecting rod 101 is integrally provided at one end of the handle 1, and a fixing hook 102 is fixedly installed at one end of the connecting rod 101;

[0020] The connecting rod 101 is provided with an adjusting mechanism which can adjust the position of the hook head.

[0021] Reference Figure 1-3 In this embodiment, the adjustment mechanism includes a slide groove 1012, a movable hook 103, an adjustment rod 1032, a long rod adjustment screw 1033, and a threaded hole 104. The middle of the connecting rod 101 is provided with a slide groove 1012, and the adjustment rod 1032 is slidably connected inside the slide groove 1012. The upper end of the adjustment rod 1032 is fixedly installed with a movable hook 103. The handle 1 and the connecting rod 101 are provided with a threaded hole 104. The long rod adjustment screw 1033 is threadedly connected inside the threaded hole 104, and the end of the long rod adjustment screw 1033 is rotatably connected to the adjustment rod 1032. The protrusions on the movable hook 103 and the fixed hook 102 are symmetrically arranged. The hook heads of the movable hook 103 and the fixed hook 102 are both provided with protrusions, and the height of the protrusion is 1.5 mm and the width is 3 mm.

[0022] As needed, the long rod adjusting screw 1033 is rotated, and the long rod adjusting screw 1033 moves along the threaded hole 104 toward the movable hook 103, pushing the adjusting rod 1032 to move horizontally along the slide groove 1012, and adjusting the position of the movable hook 103 to achieve the purpose of adjusting the distance between the movable hook 103 and the fixed hook 102. The medical staff holds the handle 1 and uses the fixed hook 102 and the movable hook 103 to pull and fix the muscles during the strabismus surgery, avoiding uneven force of the assistant causing inaccurate muscle volume, while reducing manpower during the operation. The protrusions at the hook heads of the movable hook 103 and the fixed hook 102 can prevent muscle slippage.

[0023] Reference Figure 1-3 In this embodiment, a scale line 1011 having the same length as the slide groove 1012 is engraved on one side of the connecting rod 101, and the length of the scale line 1011 is 20 mm. A positioning plate 1031 is fixedly installed on one side of the bottom of the movable hook 103, and the positioning plate 1031 points to the scale line 1011;

[0024] The position of the movable hook 103 is adjusted according to the scale line 1011 until the positioning plate 1031 points to the corresponding scale.

[0025] Working principle: First, the medical staff holds the handle 1, and turns the long rod adjusting screw 1033 against the scale line 1011. The long rod adjusting screw 1033 moves along the threaded hole 104 toward the movable hook 103, and pushes the adjusting rod 1032 to move horizontally along the slide groove 1012, and adjusts the position of the movable hook 103 until the positioning plate 1031 points to the corresponding scale, thereby achieving the purpose of adjusting the distance between the movable hook 103 and the fixed hook 102. Then, the fixed hook 102 and the movable hook 103 are used to pull apart and fix the muscles during the strabismus surgery to avoid inaccurate muscle volume caused by uneven force of the assistant, while reducing manpower during the operation. The protrusions at the hook heads of the movable hook 103 and the fixed hook 102 can prevent muscle slippage.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
