[0002] In the development of modern medical technology, the precision and safety requirements of ophthalmic surgery are increasingly high. As an important surgical auxiliary tool, the eyelid skin drag hook plays a key role in ophthalmic surgery.
[0003] The traditional skin drag hook structure is relatively simple, which is usually composed of a hook body and a hand-held rod. In use, the medical staff holds the hand-held rod, and the hook body of the eyelid skin drag hook is gently placed on the skin of the eyelid to ensure that the hook body firmly holds the eyelid, thereby facilitating the operation of the medical staff. During the operation or detection process, when it is necessary to observe a wider or deeper field of view for a short time, the medical staff often decides to perform secondary stretching. This often involves readjusting the position of the drag hook or using a second drag hook to help further stretch the eyelid, and after the short observation, the drag hook position is restored or the second drag hook is removed, which is relatively troublesome. Therefore, a compound type eyelid skin drag hook is needed, which can facilitate secondary stretching without adjusting the position of the drag hook or adding a second drag hook, so as to achieve the effect of compound stretching.
