Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to a line drawing tool which can accurately control the distance between a drawing line and a palpebral margin when drawing a line before double eyelid surgery. Background Art

[0002] Double eyelid surgery, also known as double eyelid plasty, is one of the most common surgeries in plastic surgery. Generally speaking, double eyelids visually increase the eye contour, add a three-dimensional sense to the eye, make the eyes appear larger, and make the eyelashes curl upward, giving people a vivid and lifelike feeling. Single eyelids have thicker eyelids and drooping eyelashes, which makes the eyes appear smaller, dull and lifeless. Orientals have more single eyelids, so many people seek surgery.

[0003] Before double eyelid surgery, the double eyelid line needs to be designed, mainly to determine the location of the incision based on the double eyelid shape that the patient prefers. During the design stage, the patient can have an intuitive understanding of the shape of the double eyelid after surgery, and the doctor can also have an intuitive understanding of the specific condition of the patient's eyelid after surgery, and preliminarily determine whether there is hidden ptosis, the condition of the upper eyelid levator muscle, and the amount of skin removed.

[0004] At present, when drawing lines to clarify the incision position during the design stage, surgeons often use freehand drawing or a spacing ruler to draw lines. When drawing lines, first draw points at specified positions around the eyes, specifically at a specific distance from the lower edge of the upper eyelid, and then smoothly connect the points to form a double eyelid line. The above-mentioned line drawing method requires the surgeon's hand to maintain a high degree of stability, otherwise it is easy to have problems with unsmooth lines when connecting the points; in addition, after drawing on one eye, it is necessary to draw a line on the other eye. For the sake of beauty, the two lines need to be basically symmetrical, which is very difficult for pure manual line drawing. Therefore, the existing line drawing method often has problems such as inaccurate spacing between the line and the eyelid margin or asymmetric lines between the two eyes. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that there is no dedicated tool for drawing lines before blepharoplasty, and the lines are generally drawn by hand, resulting in inaccurate distance between the drawn line and the eyelid margin or asymmetry of the lines drawn on both eyes, so as to provide a tool for drawing lines before blepharoplasty that can make the lines drawn on both eyelids more accurate and more symmetrical.

[0006] To this end, the utility model provides a preoperative line drawing tool for double eyelid surgery, comprising:

[0007] Top border;

[0008] A lower frame is arranged opposite to the upper frame and is evenly provided with a plurality of through holes;

[0009] There are two side frames, which are arranged in parallel and opposite to each other, and the two ends of the side frames are respectively fixedly connected to the two ends of the upper frame and the lower frame;

[0012] There are multiple adjusting rods, which are respectively installed in the through holes and frictionally and slidably cooperate with the through holes. One end of the adjusting rod passes through the through hole and is located outside the drawing space, and the other end is located in the drawing space and fixedly connected to the drawing ruler.

[0013] Furthermore, the upper frame, the lower frame and the marking ruler are all made of soft polyvinyl chloride plastic.

[0014] Furthermore, the adjusting rods include a plurality of adjusting rods, and the distance between two adjacent adjusting rods is 2-8 mm.

[0015] Furthermore, the distance between two adjacent adjusting rods is 4-5 mm.

[0016] Furthermore, the adjusting rod is provided with scale values.

[0017] Furthermore, the end of the scale value set on the adjusting rod that contacts the marking ruler is the starting end.

[0018] Furthermore, a guide groove is provided along the length direction on the inner wall of the side frame facing the drawing space, and guide protrusions are provided at both ends of the drawing ruler. The guide protrusions are slidably matched with the guide grooves to guide the two ends of the drawing ruler to move up and down relative to the side frame.

[0019] Furthermore, the guide protrusion is a sphere.

[0020] Furthermore, a friction coating is provided on the inner wall of the through hole; under the action of external force, the adjustment rod can move up and down relative to the through hole; after the external force disappears, under the action of friction force, the adjustment rod can be temporarily fixed relative to the through hole.
