Francis Chalazion Clamp Oval, Medium

Product Description: Francis Chalazion Clamp, Oval, Medium A specialized hemostatic and stabilization clamp designed for precise, controlled, and bloodless surgery on eyelid lesions. Executive Summary The Francis Chalazion Clamp is a quintessential ophthalmic instrument used primarily for the excision of chalazia (blocked meibomian gland cysts) and other minor eyelid procedures. Its unique ring-and-loop design provides simultaneous hemostasis (control of bleeding), stabilization of the eyelid, and protection of the eyeball. The oval, medium size is a versatile choice suitable for a wide range of adult patients and common lesion sizes. Key Features & Components 1. Oval Screw Plate (The "Spoon" or "Ring"): Shape: The defining feature is its oval-shaped plate. This design provides a larger and more elongated working area compared to circular spoons, making it ideal for the natural contour of the tarsal plate and for managing larger or more oblong chalazia. Function: This plate is placed on the inner conjunctival surface of the eyelid. It serves three critical purposes: Stabilization: It provides a firm, stable platform to exert and immobilize the eyelid. Hemostasis: The serrated rim and pressure from the clamp's closure control bleeding by compressing the blood vessels around the surgical site. Protection: It acts as a physical barrier, protecting the sensitive cornea and the globe itself from accidental scalpel slips during the procedure. 2. Solid Open Loop (The "Loop"): Design: The opposing jaw is a solid, open loop. Function: This loop is placed on the external skin surface of the eyelid. It applies counter-pressure to the screw plate, sandwiching the eyelid tissue securely. The open center allows the surgeon to see and palpate the lesion from the outside and provides an access point for external incision if needed. 3. Screw-Locking Mechanism: Design: A threaded screw with a large, knurled knob is located on the arm of the loop side. Function: Rotating the screw tightens the two jaws together, allowing the surgeon to apply precise and adjustable pressure. Once the desired pressure is achieved to achieve hemostasis, the clamp locks securely in place, freeing the surgeon's hands for the excision. 4. Box-Lock Joint: Design: A robust, precision-engineered hinge that connects the two arms. Function: Ensures smooth, parallel alignment of the jaws without wobbling or misalignment, providing even pressure distribution across the entire ring and loop. 5. Material and Finish: Material: Manufactured from high-quality, medical-grade stainless steel. Finish: Typically features a satin/matte finish. This reduces glare under bright surgical lights, which is crucial for precision work. How It Is Used in a Chalazion Procedure Anesthesia: Local anesthetic is administered. Application: The eyelid is everted (flipped inside out). The oval screw plate is positioned on the inner surface of the lid, directly over the chalazion. Clamping: The loop is closed over the external skin, and the screw is tightened until the lid is firmly immobilized and hemostasis is achieved. Incision & Curettage: A vertical incision is made through the conjunctiva inside the ring. The chalazion's contents are then scraped out (curettage) with a specialized instrument. Release: The screw is loosened, and the clamp is gently removed. Why the "Oval, Medium" Size is Versatile Oval Shape: Conforms better to the anatomy of the tarsal plate, providing a larger and more secure working field than a circular clamp of similar width. Medium Size: Fits the majority of adult eyelids and chalazia, making it the most commonly used and essential size to have available. Small sizes may be too restrictive, while large sizes can be cumbersome for average cases. Common Applications Primary Indication: Excision and curettage of chalazia and internal hordeola (infected glands). Secondary Uses: Biopsy of eyelid masses, removal of small conjunctival cysts, or any minor eyelid procedure requiring hemostasis and stabilization.

• Oval-Shaped Ring: The medium-sized, oval ring is designed to fit comfortably around the eyelid and encircle the chalazion (blocked meibomian gland). This provides a stable and contained surgical field.
• Solid Plate & Open Ring: One side is a solid plate that provides a firm, flat surface on the outer eyelid skin. The other is an open ring that allows the inner conjunctival surface to bulge through, presenting the chalazion for easy access.
• Screw-Lock Mechanism: Features a threaded screw that, when tightened, locks the clamp securely in place at the desired pressure.
• Stainless Steel Construction: Made from high-quality, medical-grade stainless steel, ensuring durability and the ability to withstand repeated sterilization.
• All-in-One Functionality: Combines stabilization, hemostasis, and exposure in a single instrument, streamlining the surgical process
• Enhanced Safety: The hemostatic effect prevents bleeding that could obscure the surgeon's view, reducing the risk of complications.
• Procedural Control: The screw-lock provides precise control over the clamping pressure, and the solid plate protects the outer eyelid and globe from the scalpel.
• Procedure-Specific Design: It is the standard and most effective tool specifically designed for chalazion surgery.
