[0019] Example
[0020] The ophthalmic surgery marking pen described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 3As shown, it includes a pen body 1, both ends of the pen body 1 are fixed with fixed heads 8, the two fixed heads 8 are respectively provided with marks 7 for distinguishing the left and right eyes, the fixed heads 8 are both threadedly connected with pen caps 5, a sliding sleeve 2 is independently sleeved on the pen body 1, a plurality of limit strips 4 are fixed on the sliding sleeve 2, the plurality of limit strips 4 are distributed in a circular array along the central axis of the sliding sleeve 2, a locking nut 3 is threadedly connected on the limit strip 4, a mounting shell 9 is fixed on the side wall of the sliding sleeve 2, a rotating shaft 14 is provided in the mounting shell 9, the rotating shaft 14 is rotatably connected to the inner wall of the mounting shell 9, two fixing rings 13 are sleeved on the rotating shaft 14, a measuring ruler 10 is wound between the two fixing rings 13, a through slot for the measuring ruler 10 to extend is provided on the front side wall of the mounting shell 9, a locking nut 3 is sleeved on the fixing ring 13 and the inner wall of the mounting shell 9 The coil spring 12 on the rotating shaft 14 has fixed heads 8 welded or pasted at both ends of the pen body 1, and the fixed heads 8 are pasted with labels 7, and the two labels 7 are respectively "L" and "R", "L" is used to represent the left eye, and "R" is used to represent the right eye, and the two labels 7 can also be distinguished by different colors, for example, "L" is red, and "R" is black, which is convenient for medical staff to check patient information more intuitively, and the fixed head 8 is provided with an external thread, and the inner wall of the pen cover 5 is provided with an internal thread that is threadedly matched with the external thread, so that the pen cover 5 is covered on the fixed head 8 to cover and protect the label 7; and in order to better distinguish the two pen covers 5, "L" and "R" can also be printed on the two pen covers 5 respectively, so that the label 7 can be viewed more intuitively, and the corresponding pen cover 5 can be opened according to needs;
[0021] When the cam 2 is in the state of being loosened, the cam 2 is in the state of being loosened, and the cam 2 is in the state of being loosened, so that the cam 2 is loosened, and the cam 2 is in the state of being loosened, so that the cam 2 is loosened, and the cam 2 is in the state of being loosened, so that the cam 2 is loosened, and the cam 2 is in the state of being loosened, and the cam 2 is in the state of being loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened, so that the cam 2 is loosened, and the cam 2 is loosened.
[0022] The side wall of the sliding sleeve 2 is welded or glued with a mounting shell 9, and a rotating shaft 14 is arranged in the mounting shell 9 to be rotatably connected thereto. When the rotatable connection scheme is implemented, countersunk holes are opened on the left and right inner walls of the mounting shell 9, and bearings are installed in the countersunk holes. The outer rings of the bearings are welded to the inner walls of the countersunk holes, and the inner rings of the bearings are welded with the ends of the rotating shaft 14. The rotating shaft 14 is freely rotated in the mounting shell 9 through the bearings. Two fixing rings 13 are welded or glued to the rotating shaft 14, and a coil spring 12 is arranged between the inner wall of the mounting shell 9 and the fixing ring 13. , two coil springs 12 are both mounted on the rotating shaft 14 between the mounting shell 9 and the fixing ring 13, one end of one coil spring 12 is welded to the left inner wall of the mounting shell 9, and the other end thereof is welded to the left side wall of the fixing ring 13 on the left; one end of the other coil spring 12 is welded to the right inner wall of the mounting shell 9, and the other end thereof is welded to the right side wall of the fixing ring 13 on the right; a measuring ruler 10 is wound around the rotating shaft 14, one end of the measuring ruler 10 is adhered to the rotating shaft 14, and the other end thereof extends out of the through slot of the front side wall of the mounting shell 9 and is located outside the mounting shell 9;
[0023] like Figure 2 As shown, a handle 11 is fixed to the movable end of the measuring ruler 10, and the movable end of the measuring ruler 10 extending out of the through slot on the front side wall of the mounting shell 9 is adhered with the handle 11. The length of the through slot on the front side wall of the mounting shell 9 is smaller than the length of the handle 11. Under the torsional force of the coil spring 12, the measuring ruler 10 extending out of the mounting shell 9 is driven to be rewound around the rotating shaft 14. Due to the action of the handle 11, the handle 11 is stuck on the front side wall of the mounting shell 9 at the through slot, so that the medical staff can pull the measuring ruler 10 out of the mounting shell 9 by pulling the handle 11, and measure about 3 cm above the eyebrow arch of the patient's eye, so that the position of the mark 7 is more accurate and the mark 7 can be avoided from being blurred.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the front and back sides of the measuring ruler 10 are printed with scale lines. By using the scale lines on the front and back sides of the measuring ruler 10, no matter which mark 7 is used at both ends of the pen holder 1, the position from the eye to the mark 7 can be measured, which is more convenient to use and makes it more practical.
[0025] like Figure 1 As shown, the pen cap 5 is provided with an ink pad 6 in contact with the mark 7. The ink pad 6 is pasted in the pen cap 5. When the pen cap 5 is covered on the fixed head 8, the mark 7 is in contact with the ink pad 6, so that the ink in the ink pad 6 is stained on the mark 7. The mark 7 can be used to mark the patient's eyes, and the ink in the ink pad 6 adopts natural, environmentally friendly and non-toxic pigments. The natural, environmentally friendly and non-toxic pigments will not cause harm to the human body during use, and the mark 7 is not easy to blur. The mark 7 is clearer and more vivid, which is convenient for medical staff to verify the eye mark and avoid the occurrence of eye mark errors as much as possible.
[0026] In actual use, for the eye of the patient to be operated on, the corresponding pen cap 5 is opened to expose the mark 7, and then the locking nut 3 is rotated to loosen the squeezing of the plurality of limit strips 4, so that the sliding sleeve 2 moves on the pen holder 1 to make it close to the relevant mark 7, and then the locking nut 3 is rotated to tighten the plurality of limit strips 4, so that the limit strips 4 are firmly fixed on the pen holder 1, the position of the sliding sleeve 2 is fixed, and then the measuring ruler 10 is pulled. When the measuring ruler 10 is pulled, the rotating shaft 14 is driven to rotate in the mounting shell 9, thereby driving the fixed The fixed ring 13 rotates accordingly, causing the coil spring 12 to twist, and the measuring ruler 10 is used to measure the eye to about 3 cm above the eyebrow arch, and the mark 7 is used to mark this position, and then the measuring ruler 10 is loosened. Under the torsional force of the coil spring 12, the fixed ring 13 is driven to rotate, and the fixed ring 13 drives the rotating shaft 14 to rotate, so that the measuring ruler 10 extending out of the mounting shell 9 is wrapped around the measuring ruler 10 again, so that the position of the mark 7 is more accurate, and the mark 7 is avoided from being blurred, which is convenient for medical staff to verify the eye mark to prevent the occurrence of wrong surgical sites.
