Gass Corneoscleral Punch

The Gass Corneoscleral Punch: Advanced Flexibility for Glaucoma Surgery

This Gass Corneoscleral Punch is a specific instrument that is designed to create precise openings for sclerostomy during the trabeculectomy procedure. It is named after the renowned Ophthalmologist Dr. J. Donald Gass. This punch is designed to address the difficulties of positioning commonly encountered during glaucoma filter surgery. With a 1.5mm in diameter, a head and a 0.75mm wide bite, it offers a uniform opening, and its rotational tip gives you the most convenient surgical experience.

The Advantage of the Rotatable Tip

The main characteristic of this Gass model is the 360-degree rotating tip. When performing traditional punches, the surgeon might require a shrewd angle of their wrist or the patient's eye to align the cutting edge in the vicinity of limbal tissue.

• Easy positioning: The ability to turn the head around allows surgeons to keep an ergonomic, comfortable hand position while also adjusting the punch to match the exact location that runs through the scleral flap.
• Access Enhanced: This flexibility is particularly helpful for eyes with deep-set orbits or when operating on small surgical areas where mobility is limited.
• Precision Alignment. By turning the tip, the surgeon is able to make sure that the 0.75mm deep slit is in perfect alignment with the tissue, leading to an easier, cleaner drainage channel.

Technical Specifications: 1.5mm Head & 0.75mm Bite

Sizes and dimensions for The dimensions of the Gass punch are calibrated to allow for optimal flow of aqueous humor:

1. 1.5mm Diameter Head The slightly bigger head (compared with 0.6mm and 1.0mm micro-punches) is specifically designed to suit surgeons who would prefer an sclerostomy that is more durable. It provides a clear space that's not vulnerable to postoperative occlusion that occurs early.
2. 0.75mm The Deep Bite. This depth has been designed to penetrate the entire length of the limbal sclera without risking the deeper uveal tissue. This is the key to achieving a predictable drop in intraocular pressure (IOP).
3. Shearing action: The punch utilizes an exact shearing mechanism that cuts a smooth circular, semi-circular or circular piece of tissue. It leaves soft edges that prevent over scarring.

Surgical Versatility

Although it is most commonly used for Trabeculectomy and other surgical procedures, this Gass Corneoscleral Punch is also an ideal instrument to:

• The Deep Sclerectomy: Assisting in the removal of the deep scleral fold that is deep.
• Non-penetrating Glaucoma Surgery (NPGS): The creation of controlled drainage sites using advanced techniques of filtration.

Premium Construction

To help support its complicated rotational mechanism The Gass punch is constructed to the highest standards:

• Surgical grade stainless steel: The rotating joint is guaranteed to be smooth, and the cutting edges stay sharp during repeatedly sterilization.
• Squeeze-Action handle: Gives you the sensitivity needed to detect the "snap" of the tissue being struck.
• Glare-Free Finish : A satin finish blocks the reflection of light under the microscope of a surgical procedure while ensuring high contrast visualization of the limbus.

Conclusion

This Gass Corneoscleral Punch is an excellent option among surgeons who value the ergonomics of their work and technical precision. The rotatable head turns an arduous maneuver into a smooth, repeatable step, which provides the most effective base for a practical filtering bleb.
