The Covidien EEA Black Circular Stapler with Tri-Staple Technology, 33mm Extra is another variant of the circular stapler used primarily for gastrointestinal (GI) surgeries, specifically for anastomosis procedures. Here's a more detailed breakdown:

Key Features:

1. Tri-Staple Technology: Like other staplers in this series, the black stapler features three rows of staples with varying heights. This helps to accommodate different tissue thicknesses, offering improved tissue perfusion and healing after the stapling process.

2. Black Handle/Designation: The black stapler is designed for extra-thick tissues. It indicates that the stapler is built to handle tissues that are much thicker than what the regular or medium staplers are meant for. This may be crucial in surgeries involving tissues with higher density or rigidity.

3. 33mm Diameter: The 33mm diameter circular staple line is a commonly used size for colorectal and other gastrointestinal procedures, particularly when joining sections of bowel or other hollow organs.

4. Extra Staple Height: The "Extra" designation refers to the height of the staples, which are suited for very thick tissues. The increased staple height ensures proper closure and healing for thicker tissue segments.

Applications:

• GI Anastomosis: It's typically used for resecting and rejoining parts of the gastrointestinal tract.
• Colorectal Procedures: Often employed in procedures like low anterior resection (LAR) or other surgeries where bowel resection is required.
• Thoracic Surgery: Can also be used for lung resections when thick tissue must be stapled and divided.

This stapler is particularly valuable when dealing with extra-thick or dense tissue, ensuring that the staples close properly while maintaining adequate blood supply for healing. Would you like additional information about its usage or benefits?
