Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional ophthalmic skin marker. Background Technology

[0002] Surgical site marking is a process in which medical staff, with the participation of the patient and their family, mark the surgical site or its vicinity to prevent surgical site errors and is a means of improving surgical safety. Existing marking pens require manual marking, resulting in significant variations in the size, location, and shape of hand-drawn shapes, which hinders verification by medical staff. Furthermore, pediatric patients often have poor compliance, making it inconvenient to use surgical site marking pens on them. During surgery, the ink used for marking may become blurred or faded upon contact with disinfectants, blood, or tissue fluid, affecting the doctor's accurate identification of the surgical site and causing inconvenience. Moreover, the markings often disappear or become illegible shortly after surgery, hindering observation and assessment of the surgical site by medical staff. Therefore, currently used marking pens, while capable of marking the eye, cannot mark the surgical name or pupil, failing to fully identify the patient's surgical information, hindering information verification by medical staff, and easily leading to surgical errors or incorrect preoperative pupil preparation, resulting in irreversible mistakes. In a single surgery, it is often necessary to use multiple different marking symbols to distinguish different surgical steps and areas, but current marking pens or stamps typically only have one marking symbol, making them cumbersome and hindering rapid surgical site marking.
