Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an eye skin marking device. Background Art

[0002] In ophthalmic clinics, the surgeon needs to use a marker to draw a 1.5 cm diameter “○” shaped mark 3 cm in the middle of the eyebrow arch of the patient’s operated eye before the operation.

[0003] But existing marking pen has the following problems:

[0004] 1. It is not for ophthalmic clinical use, the marking head is a pen tip and cannot be used for circular marking;

[0005] 2. The surgeon needs to use a surgical marker to draw an "○"-shaped mark 3 cm above the eyebrow arch. The height of the mark and the circle are subjectively judged. There are problems such as different heights and shapes of marks. Therefore, the surgeon's work efficiency is low, and the mark is not standardized and not beautiful.

[0006] 3. According to hospital infection control requirements, different patients are not allowed to share the same marker pen, so the marker pen is only used once and then discarded, which is costly and wasteful. Utility Model Content

[0007] In order to solve the above technical problems, the purpose of the utility model is to provide an eye skin marking device which can be reused, saves costs and avoids waste.

[0008] The technical solution provided by the utility model is as follows:

[0009] An eye skin marking device comprises a rod body and a marking head. The marking head is detachably mounted on the rod body and contains ink for marking on the eye skin.

[0010] Preferably, the rear end of the marking head is provided with a cylindrical portion opening rearwards, the front end of the rod body is narrowed to form a step portion, and when the marking head is installed on the rod body, the cylindrical portion is sleeved on the front end, and the rear edge abuts against the step portion.

[0011] Preferably, a circular through hole is provided at the front end of the marking head for forming an “○”-shaped mark.

[0012] Preferably, the marking head is a sponge.

[0013] Preferably, it also includes a cap portion, which is located at the front end of the marking device and is used to protect the marking head.

[0023] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides an eye skin marking device, which mainly includes a rod body 2, a marking head 6, a cap 7, a positioning ruler 4, a control key 3, and a core body 11.

[0029] The marking head 6 is detachably mounted on the rod body. It is made of a sponge material. The sponge contains ink (special ink for surgical marking) for marking on the eye skin, thereby forming a disposable and replaceable independent stamp. The marking head 6 is roughly cylindrical with an open rear end. The rear end is provided with a cylindrical portion that opens toward the rear, and the middle of the front end is provided with a circular through hole for forming an "○"-shaped mark. The diameter of the circular through hole is 1.5 cm, which is slightly smaller than the diameter of the cylindrical portion.

[0030] The front end of the rod body 2 is reduced to form a step portion. When the marking head 6 is installed on the rod body 2, the cylindrical portion is sleeved on the front end portion, and the rear edge abuts against the step portion, thereby preventing the marking head 6 from moving further backward.

[0031] The cap 7 is located at the front end of the marking device to protect the marking head 6. When not in use, the cap 7 is sleeved on the front end of the marking head 6 to prevent the soft marking head 6 from being damaged.

[0032] The positioning ruler 4 is used to position the marking head 6 during marking. A receiving groove is provided at the front of the rod body (i.e., the end close to the marking head 6). The positioning ruler 4 is received in the receiving groove of the rod body 2 when not in use, so that the positioning ruler can be protected and not easily bumped. The front end of the positioning ruler 4 is mounted on the rod body 2 through a torsion spring (or a similar structure), so that the positioning ruler has a tendency to rotate 90 degrees to be perpendicular to the rod body 2. The rear end of the positioning ruler 4 is blocked by a baffle (or a similar structure), so that the positioning ruler 4 will not rotate due to the torsion spring when not in use. The baffle is connected to the control key 3, so that the baffle is controlled by the control key 3. When the positioning ruler 4 needs to be used, the baffle is removed from the positioning ruler 4. The positioning ruler 4 rotates 90 degrees to be perpendicular to the rod body 2 due to the torsion spring, and the marking head 6 can be conveniently positioned at this time. After use, the positioning ruler 4 can be rotated back to the receiving groove, and the baffle is used to block the rear end of the positioning ruler 4.

[0033] The total length of the positioning ruler 4 is 3 cm (different lengths can be customized according to the use requirements), and scales are marked on it, so that different distances can be positioned.

[0034] During operation, the operator can align the vertex 5 of the positioning ruler with the center of the patient's eyebrow arch, with the eyebrow arch and the positioning ruler at an angle of 90 degrees, so that the marking head is 3 cm above the patient's eyebrow arch, to help the operator perform accurate positioning.

[0035] The rod body 2 is a hollow structure, the core body 11 is installed in the rod body cavity, and is connected to a reset spring 9. The front end of the reset spring 9 is fixed to the inner wall of the rod body 2 through a fixing buckle, and the rear end is fixed to the core body 11. The front end of the core body 11 is close to the marking head 6, and the top extends out of the rod body 2, so that the core body 11 moves forward after being pressed at the top 1 to separate the marking head 6 from the rod body 2, and is reset by the reset spring 9 after being released.

[0036] A hook 8 is provided at the rear of the rod body 2 to hang the marking device on a pocket. The rod body 2 can be reused. When the operator uses it, it can be used by plugging it with the marking head. After marking, the top of the core body can be pressed to move the core body forward, and the front marking head can be pushed out for separation. The reset spring provided inside the rod body resets the core body after being pressed and released. When not in use, it can be hung on the pocket of clothes with the hook for easy carrying. When marking is needed next time, it can be plugged with a new marking head.

[0037] Compared with the prior art, the eye skin marking device of this embodiment can help surgeons to locate quickly and accurately, and the marking circle is more standard, beautiful, and easy to use. It greatly improves the work efficiency of surgeons and makes the skin marking of the surgical site more standardized and beautiful. At the same time, only the marking head needs to be replaced each time it is used, so that the operation is more in line with hospital infection requirements, and it can also save costs and avoid waste.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
