[0002] Eye surgery markers are indispensable tools in ophthalmic surgery. They greatly improve the accuracy and safety of surgery by providing precise positioning and clear visual markings. With the development of technology, the functions of these markers are also constantly improving, providing more convenience and protection for ophthalmologists. When selecting and using eye surgery markers, doctors need to choose the most suitable equipment according to the specific type of surgery and patient conditions to ensure the smooth progress of the operation.

[0003] However, when using the current marker, the doctor needs to hold the marker in hand and then manually draw lines on the patient's eyelids or around the eyes, so that accurate cutting can be achieved in subsequent operations; but when the doctor draws the lines manually, the doctor's drawing strength depends entirely on the feel of the hand. If excessive force is used, it is easy to cause pain and discomfort to the patient; secondly, when the doctor holds the marker in hand to draw lines around the eyes, although the doctor's hand feels good, the strength is slightly different when drawing the lines, and the skin around the glasses will be concave, resulting in the drawn lines being bent and not straight, and then needing to be wiped and redrawn, which is more cumbersome; for example, a Chinese patent (publication number: CN220275730U) discloses an eye surgery marker, which requires the doctor to hold the marker in hand for a long time during use.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figures 1 to 6 , the utility model provides a technical solution:

[0032] An eye surgery marker comprises a plurality of sliding rods 3, wherein an I-rod 4 is slidably mounted inside the sliding rod 3, and the front end of the I-rod 4 is located outside the sliding rod 3; a connecting plate 5 is fixedly mounted on one end of the I-rod 4 located inside the sliding rod 3, and adjacent ends of a plurality of the connecting plates 5 are located outside the sliding rod 3, and a support rod 6 is rotatably mounted on adjacent ends of a plurality of the connecting plates 5; a column 7 is slidably mounted on the support rod 6, and a cavity 71 is provided inside the column 7, and the lower end of the column 7 is in an open state; a threaded connector 8 is slidably mounted on the lower end of the column 7, and a marker 9 is rotatably mounted on the lower end of the threaded connector 8, and the lower end of the marker 9 is located outside the sliding rod 3. On the outside of the threaded connector 8; a second slide groove 31 is provided on the plurality of sliding rods 3, and the rear end of the I-beam 4 is slidably installed inside the second slide groove 31; a plurality of first springs 41 are fixedly installed on the rear end of the I-beam 4, and a vertical plate 42 is fixedly installed on the rear end of the first spring 41, and the rear end surface of the vertical plate 42 can fit with the inner rear end surface of the second slide groove 31; a through groove 32 is provided on the adjacent end surfaces of the plurality of sliding rods 3, and the ends of the plurality of connecting plates 5 that are away from each other pass through the through groove 32 and are located inside the second slide groove 31; a half ring 1 is rotatably installed inside two adjacent rotating rods 2, and an air cushion 11 is fixedly installed at the opening position inside the half ring 1.

[0033] By adopting the above technical scheme, most of the traditional markers 9 on the market are manually held. During the operation of the marker 9, the doctor needs to consider the strength of force when drawing the line, so as to avoid the patient from adapting. Secondly, during the process of drawing the line, the doctor needs to pause in the middle and put down the marker 9 and pick it up again after a while, which is not conducive to the operation. Therefore, compared with the traditional handheld marker 9 on the market, the structure of the present device is as follows: it includes a semi-ring 1, and the interior of the semi-ring 1 is fixedly installed with an air cushion 11 at the opening position. The semi-ring 1 can be installed on the patient's head, so that the subsequent marker 9 can always be in the doctor's field of vision, and can be operated quickly, saving the doctor's time to find the marker 9. The semi-ring 1 is rotatably installed on the outer side of the opening, and a sliding rod 3 is slidably installed on the rotating rod 2, and an I-beam 4 is slidably installed inside the sliding rod 3, and a connecting plate 5 is fixedly installed at the adjacent end of the I-beam 4, and a support rod 6 is rotatably installed at the adjacent end of the connecting plate 5, and a marker 9 is slidably installed on the support rod 6.

[0034] During use, the half ring 1 is stuck on the patient's head, and the doctor rotates the rotating rod 2 to a horizontal state. At this time, the sliding rod 3 is perpendicular to the rotating rod 2. The doctor presses the I-rod 4, and the I-rod 4 presses the first spring 41, causing the first spring 41 to contract. Then the doctor allows the I-rod 4 to slide up and down inside the second slide groove 31 to adjust the height of the lower end of the marker 9 so that the lower end of the marker 9 can contact the patient's eye skin with moderate force to avoid causing discomfort to the patient. After the adjustment is completed, the doctor releases the I-rod 4, and the first spring 41 resets itself, so that the I-rod 4 can be in a fixed state. At this time, the doctor manually pushes the column 7 to slide horizontally, and the column 7 will move synchronously with the marker 9. Movement, and during the movement of the marker 9, it can operate at the position where the patient needs to draw a line, so as to leave a colored mark, which is convenient for subsequent surgery. When the marker 9 encounters a raised skin during the process of drawing lines, the marker 9 will move upward, causing the reset spring 72 to be compressed (the elastic force of the reset spring 72 is small, and there will be no downward pressure, so as to avoid the marker 9 causing discomfort to the patient), and the column 7 can only move horizontally. Therefore, when it is necessary to draw vertical lines, the doctor needs to push the sliding rod 3 to slide back and forth inside the first sliding groove 21, so that the sliding rod 3 can move back and forth with the support rod 6, and then the support rod 6 can move synchronously with the marker 9, so that the marker 9 can draw vertical lines.

[0035] Specifically, Figures 1 to 6 As shown, a plurality of first springs 41 are fixedly installed at the rear end of the I-beam 4, and a vertical plate 42 is fixedly installed at the rear end of the first spring 41, and the rear end surface of the vertical plate 42 can fit with the inner rear end surface of the second slide groove 31; a rotating rod 2 is slidably installed at the lower end of the sliding rod 3, and a first slide groove 21 is provided on the upper end surface of the rotating rod 2, and the lower end of the sliding rod 3 is slidably installed inside the first slide groove 21; an external thread 91 is provided on the upper circumferential surface of the marker 9; a third slide groove 61 is provided on the surface of the support rod 6, and a U-shaped groove 62 is provided on the inner side walls of the third slide groove 61; two sliding blocks 73 are fixedly installed on the circumferential surface of the column 7, and the sliding blocks 73 are respectively slidably installed inside the U-shaped groove 62.

[0036] By adopting the above technical solution, the strength of the traditional handheld marker 9 on the market depends entirely on the doctor's hand feeling during the operation, and different doctors use different techniques, which leads to different pressing strengths. In order to avoid eye discomfort caused by the strength of the press, the utility model presses the I-bar 4 during use. At this time, the I-bar 4 will squeeze the first spring 41, and the first spring 41 will contract after being squeezed. At this time, the doctor can make the I-bar 4 slide up and down inside the second slide groove 31, so that the I-bar 4 can move up and down synchronously with the support rod 6, so that the support rod 6 , the height of the lower end of the marker 9 can be changed under the action of , so that the doctor does not need to consider the use of force during the line drawing process, thereby avoiding discomfort to the patient; secondly, when the traditional handheld marker 9 on the market is used, it is necessary to draw one eye before drawing another, and with the cooperation of the structure of the utility model, multiple people can perform the operation, the doctor only needs to adjust the position of the marker 9, and then move the sliding rod 3 and the column 7 to perform the operation, so that two doctors can draw lines on a single eye separately, thereby saving the time of drawing lines and improving the efficiency of doctors.

[0037] Working principle: First, the half ring 1 is installed on the patient's head, the rotating rod 2 is manually rotated, the I-beam 4 is pressed, and the height of the I-beam 4 is adjusted, so that the I-beam 4 can adjust the height synchronously with the support rod 6.

[0038] Secondly, during the adjustment process, move the column 7 so that the column 7 moves with the marker 9, and the marker 9 can move to a suitable position.

[0039] After the adjustment is completed, the doctor moves the marker 9 to draw the lines. After the horizontal lines are drawn, the doctor moves the sliding rod 3 back and forth, so that the sliding rod 3 can move the supporting rod 6 back and forth.

[0040] While the support rod 6 is moving forward and backward, it can work synchronously with the marker 9, so that the marker 9 can draw vertical lines forward and backward, and thus the marker 9 can complete the horizontal and vertical line drawing operations.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
