[0002] In ophthalmic surgery, precise manipulation is crucial to ensuring a successful procedure. The use of contact devices is particularly important, helping surgeons precisely position and secure surgical instruments, thereby improving surgical precision and efficiency. Furthermore, contact devices protect the eyes, preventing accidental injury during surgery.

[0003] Existing technology solutions: Existing contact devices typically use negative pressure to secure the eye. These devices typically consist of a lens that contacts the eye and a negative pressure chamber that generates negative pressure, allowing the lens to adhere to the eye. However, traditional contact devices often lack consistent and secure negative pressure, which can hinder surgical procedures.

[0004] Problems with existing technology: First, the negative pressure applied is difficult to control uniformly, and the anti-slip pattern used cannot prevent the eyeball from rotating circumferentially, which can cause the lens to shift on the eye, affecting surgical precision. Second, existing equipment is complex and difficult to disassemble, which can also affect assembly accuracy. Utility Model Content
