Stainless Steel Capsulorhexis for. 11mm Vaulted Shanks 102mm Long

Intended Use/Discipline : Ophthalmology Instrument : Capsulorhexis Forceps Capsulorhexis Forceps: Vaulted Shanks, Delicate Shaft General Overview: This is a highly specialized, single-purpose ophthalmic instrument designed exclusively for performing the critical Continuous Curvilinear Capsulorhexis (CCC) step in cataract surgery. Its unique geometry—featuring vaulted (angled) shanks—is engineered to allow optimal access to the lens capsule through a modern, small-incision approach. Detailed Specifications & Features: 1. Anatomical Design & Dimensions: The design is a masterclass in surgical ergonomics for a specific approach: Overall Design: Vaulted or Angled Shanks. This is the defining feature. The forceps have a distinct upward bend or angle (the "vault") in the shank, approximately 11mm from the tip. Shaft: 102mm Long, Delicate. The long, slender, and delicate shaft provides the reach necessary to navigate through the corneal incision and into the anterior chamber of the eye without obstructing the surgeon's view. Tips: 10mm Long, Ultra-Fine. The tips are exceptionally fine and smooth, designed to securely grasp the fragile, elastic anterior lens capsule without tearing it. The 10mm length provides a larger, more controlled gripping surface for the capsule flap. 2. Functional Purpose: Primary Function: To cleanly grasp, tear, and maneuver the anterior lens capsule in a perfect, continuous circular opening (the capsulorhexis) during cataract surgery. Why the Vault is Critical: The 11mm vault allows the instrument to enter through a clear corneal incision (typically 2.2-2.8mm) and position the tips parallel to the plane of the lens capsule. This provides the mechanical advantage needed to apply tangential (sideways) force for a controlled tear, rather than an upward-pulling force that could cause a radial tear (a "Canadian Tear"). 3. Key Components & Characteristics: Tips: Shape: Typically feature a 0.9mm wide, smooth, platform-style or serrated grasping platform. Action: The tips meet with precise alignment to pinch the capsule flap securely without slipping. Material: Often made of high-grade stainless steel, and may feature Titanium coating for reduced glare or Diamond-Like Carbon (DLC) coating for extreme smoothness and durability. Handles & Mechanism: Action: Spring-loaded handle that provides a comfortable, non-slip grip and allows for fine, graded control of the tip closure. Lock: Typically non-locking to allow for rapid, fluid adjustment and release of the capsule during the circular tear. 4. Surgical Application: This instrument is used in one of the most critical steps of phacoemulsification cataract surgery. A perfectly performed CCC is essential for: Containing the artificial intraocular lens (IOL) within the capsular bag. Providing a strong, continuous edge that resists tearing during phacoemulsification. Ensuring the long-term stability and centration of the IOL. 5. Key Advantages: Optimal Access: The vaulted design is indispensable for coaxial surgery through small incisions, preventing wound distortion and iris prolapse. Superior Control: The delicate shaft and long, fine tips offer exceptional tactile feedback, allowing the surgeon to "feel" the capsule tear. Precision Engineering: Designed specifically to prevent the most common serious complication of the CCC—the radial extension of the tear. Enhanced Visualization: The slender profile and potential for anti-glare coatings minimize visual obstruction and light reflection.

• Perfect CCC Formation: The primary benefit is enabling the creation of a continuous, strong, and circular opening in the lens capsule. A well-performed CCC is crucial for the safety and success of the entire cataract procedure, ensuring the IOL remains securely positioned.
• Fine Tip Control: The delicate tips allow the surgeon to grasp and tear the incredibly thin (microns thick) and elastic lens capsule with utmost control, preventing radial tears that can lead to complications.
• Vaulted (Angled) Shanks: This is the key feature. The 11mm vault creates a gentle curve in the shaft of the forceps.
• Benefits: This vault allows the instrument to be inserted through a small corneal incision and then vault over the iris without causing damage, providing direct, coaxial access to the anterior capsule.
• mproved Visualization: It keeps the surgeon's hand and the instrument handle out of the line of sight, offering an unobstructed view of the capsule during the entire delicate procedure.
• Optimal Length (102mm): This specific length is designed to work perfectly within the confined space of the eye, providing excellent balance and control while allowing the hand to rest steadily.
• Secure Capsule Grasp: The tips are designed to firmly and reliably grasp the delicate lens capsule without slipping, which is essential for maintaining control of the capsular flap during the circular tear.
• Reduced Tissue Trauma: The design is specifically made to be atraumatic to other intraocular structures like the cornea and iris when inserted and manipulated correctly.
• Stainless Steel: Guarantees the instrument is corrosion-resistant, durable, and can undergo repeated sterilization in an autoclave, maintaining its precise alignment and function over a long lifespan.
• The vaulted shank provides direct, unobstructed access to the lens capsule.
