Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an ophthalmic surgery marking tool. Background Art

[0002] The surgical mark is a method of marking when a patient is about to be pushed onto the operating table. The surgeon will use a special pen to draw a "cross" mark on the surgical site. Then, after confirmation by the surgeon, ward nurse, anesthesiologist, operating room nurse and the patient, and repeated checks, the surgery can begin. Its purpose is to ensure the safety of the patient.

[0003] Currently, the most common marking method is to use a special marker pen for marking. Although the marking pens in the prior art have overcome the problems of handwritten marking and the trouble of cleaning, the problem of difficult positioning of surgical marks still exists in existing eye surgeries. At the same time, the existing marking pens cannot be recycled, and the pen tips are easily dried out due to long-term exposure to the outside, and pigment residues will clog them and cause them to malfunction. Therefore, an ophthalmic surgical marking tool is proposed to solve the above problems. Utility Model Content

[0008] The beneficial effects of the utility model are:

[0009] During use of the ophthalmic surgery marking tool, the positioning component is first used to align the patient's position to be marked, and then the pressing cover is pressed downward, thereby driving the seal holder to move downward through the liquid storage tube. During this process, the push plate moves downward, thereby driving the rotating component to rotate, so that the bottom of the installation cylinder is opened, and the seal holder can be moved to the bottom of the positioning component, so that it is marked by the marking component. It has the advantages of being easy to use and preventing volatilization.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the marking component includes a liquid transfer rod and a marking stamp, the interior of the stamp seat is fixedly connected with the liquid transfer rod extending into the liquid storage tube, the interior of the stamp seat is fixedly connected with a marking stamp connected to the liquid transfer rod, and the liquid transfer rod is made of nylon fiber.

[0012] The beneficial effect of adopting the above further solution is that the fuel in the liquid storage tube can be transported to the inside of the marking stamp through the liquid transfer rod.

[0013] Furthermore, the positioning assembly includes a positioning spring, a telescopic rod and a positioning ring. The interior of the mounting tube is fixedly connected with a positioning spring, the bottom of the positioning spring is fixedly connected with a telescopic rod, and the bottom of the telescopic rod is fixedly connected with a positioning ring adapted to the marking stamp.

[0014] The beneficial effect of adopting the above further solution is that the position to be marked can be circled by the positioning ring.

[0015] Further, the sealing assembly includes a moving shaft, a limit plate, a return spring and a sealing plate, the moving shaft is movably connected inside the mounting tube, the top of the moving shaft is fixedly connected to the limit plate, the bottom of the limit plate is fixedly connected to the return spring located outside the moving shaft, and the bottom of the moving shaft is fixedly connected to the sealing plate adapted to the mounting tube;

[0016] Furthermore, the rotating assembly includes a sliding seat and a rotating screw rod, the interior of the mounting cylinder is fixedly connected with the sliding seat, and the interior of the sliding seat is movably connected with a rotating screw rod whose bottom is fixedly connected to the limiting plate and adapted to the pushing piece.

[0017] The beneficial effect of adopting the above further solution is that the push piece moves downward, thereby pushing the rotating spiral rod to rotate, thereby driving the sealing plate to separate from the mounting cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
