Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1, a marking pen 100 according to a preferred embodiment of the present invention for implanting an astigmatic intraocular lens includes a pen body 1, wherein the pen body 1 contains a dye; a coloring part 2, wherein the coloring part 2 is arranged at the end part of the pen body 1, and the dye flows out from the coloring part 2; and a cutting part 3, the cutting part 3 being provided at the front end of the coloring part 2.
There are various choices of the above dyes, and in this example, gentian violet is selected as the dye.
When the utility model is used, a medical worker holds the marking pen 100 of the utility model, under the guidance of a slit lamp slit light band, the marking pen 100 is pressed or slightly scratched through the pen main body 1 from a point A to be marked, the cutting part 3 punctures or scratches corneal epithelium, the coloring part 2 contacts cornea and marks the point A; and marking a marking point B by the same method. So far, utilize the utility model discloses a marking pen 100 can accomplish the operation of drawing out of corneal epithelium and the clear and tiny mark operation of mark point A, B, need not utilize the syringe needle to draw out the corneal epithelium earlier, then uses the marking pen to carry out the painted mark.
Of course, the marking operation of the marking points a or B can be completed independently by using the marking pen 100 of the present invention, and the corneal epithelium can be scratched out independently.
The utility model discloses a focus is on, and medical personnel can utilize alone the utility model discloses a marker pen 100 can accomplish the operation of drawing apart of corneal epithelium and the clear and tiny mark operation of mark point A, B, need not utilize the syringe needle to draw apart the corneal epithelium earlier, then uses the marker pen to carry out the mark of colouring to simplify the operation step that astigmatism corrected intraocular lens was implanted, and shorten its operation time.
The cutting part 3 extends 10-30 μm from the end face of the coloring part 2. Since the corneal epithelium has a thickness of about 30 μm, the cutting portion 3 extends outward by 10-30 μm to fit the thickness of the corneal epithelium, preventing the cutting portion 3 from being too short to cut open the corneal epithelium or too long to damage other ocular structures such as the corneal stroma.
The cutting portion 3 is needle-shaped or blade-shaped. The needle-like or blade-like cutting portion 3 is sharp, and facilitates the incision of corneal epithelium.
In addition, the existing marking pen 100 is universal and is suitable for dermatology, plastic surgery and the like, the pen head is thick, when the cornea is marked, due to halation, the marking point is large, and deviates from a preoperative marking method suggested by the consensus of experts in clinical application of artificial lenses for astigmatism correction in China (2017). The method is characterized in that a marker makes horizontal marks at 3 points and 9 points under a slit lamp microscope by using a No. 4.5-5.0 syringe needle and a sterile superfine medical operation marking pen (the line width is 0.5mm), the marking part is dry as much as possible, and the marking point is as fine as possible. The guidance of "about 5 ° after marking by the marking pen 100 used clinically at present affects the accuracy of intraocular lens implantation, and thus affects the astigmatism correction ability. And the utility model discloses can also regard as the mark point through the seal of a government organization in old china that operation in-process discernment needle-like or blade form cutting part 3 left, this seal of a government organization in old china is equivalent to a thin point or short fine rule, has reduced the scope of mark point greatly, improves intraocular lens implantation's accuracy, and then improves astigmatic correction ability.
The marker 100 is placed in a disposable sterile package. After the medical staff is reminded to use the marking pen 100 and the disposable sterile packaging bag are discarded, so as to prevent the risk of corneal infection caused by repeated sterilization and use.
