Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an ophthalmic surgical retractor. Background Art
[0002] During strabismus surgery, the strabismus retractor needs to be used repeatedly to separate and cut the muscles. During the operation, the strabismus retractor is usually used to hook the muscle to separate the muscle from the surrounding tissue. On this basis, the muscle is sutured with double loop sutures, and then the muscle is cut along the edge of the strabismus retractor and the sclera with scissors. Because the other side of the strabismus hook is a double loop suture, the eye tissue is relatively fine, and the distance between the suture and the sclera is only a few millimeters, so there is a greater risk when cutting the muscle, which can easily injure the sclera by mistake or cause the muscle to slip when the suture is cut. Either situation can cause serious consequences.
[0003] The existing strabismus retractor has a single function and has no anti-slip and fixing devices. It is very easy to slip off, thereby increasing the risk of surgery and prolonging the operation time. Repeated operations are likely to cause more damage to the muscles and surrounding tissues.
