Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a bone-biting forceps for ophthalmic surgery. Background Technology

[0002] Bone forceps are a type of forceps used in orbital surgeries (such as orbital fracture repair, orbital decompression, dacryocystorhinostomy, optic nerve decompression, etc.) to precisely bite, trim, or remove orbital bone and sinus-related bone tissue. In complex ophthalmic surgeries, especially those involving the orbital bone wall, precise and safe handling of bone tissue is crucial.

[0003] However, during orbital surgery using bone forceps, fluid may drain from blood vessels or other organs. The bone forceps cannot wash away this fluid, causing contamination of the surgical wound and affecting the doctor's vision. Utility Model Content
