Sidewall-holed needle for anterior chamber infusion

Area of Science:

• Ophthalmology
• Surgical Instrumentation
• Medical Device Design

Background:

• Anterior chamber infusion is crucial for maintaining ocular integrity during intraocular surgery.
• Existing infusion techniques can pose risks due to sharp instruments within the anterior chamber.
• Unobstructed surgical fields and globe mobility are essential for successful ophthalmic procedures.

Purpose of the Study:

• To describe a novel solid-tipped, sidewall-holed needle for anterior chamber infusion.
• To highlight the safety and efficacy features of this new surgical tool.

Main Methods:

• The needle is inserted through the corneal limbus and advanced across the anterior chamber periphery.
• The needle features a solid tip and sidewall holes, with specific entry and exit points described.
• Fixation is achieved at two points, ensuring stability without obstructing the surgical field.

Main Results:

• The needle design eliminates intraocular sharp points or edges, reducing the risk of tissue damage.
• The needle is securely anchored at two fixation points, allowing for globe rotation.
• The placement ensures an unobstructed surgical field for enhanced operative control.

Conclusions:

• This solid-tipped, sidewall-holed needle provides a safer and more effective method for anterior chamber infusion.
• The design facilitates improved surgical access and maneuverability during intraocular procedures.
• It represents a significant advancement in ophthalmic surgical instrumentation.
