Circular stapler for intestinal anastomosis l Instruments in surgery l NeXT OSCE exam
A circular stapler, also known as a circular stapling device or circular stapler set, is commonly used for colorectal anastomosis. This specialized surgical stapler is designed specifically for creating a secure and airtight connection between the two ends of the colon or rectum during colorectal surgeries.
The circular stapler consists of several components that work together to create the anastomosis. Here are the key parts of a circular stapler for colorectal anastomosis:
Circular Stapling Head: The circular stapling head is the main component of the stapler and consists of a circular-shaped shaft with a stapling cartridge at one end and an anvil at the other. The stapling head is inserted into the open ends of the colon or rectum to join them together.
Anvil: The anvil is a detachable part of the circular stapler that is connected to the circular stapling head. It has a circular shape with a central rod and is inserted into the distal end of the colon or rectum. The anvil is responsible for creating the staple line on one side of the anastomosis.
Firing Mechanism: The firing mechanism is located on the handle of the circular stapler. It controls the movement of the stapling head, allowing the surgeon to deploy the staples and cut the tissue if necessary.
Safety Mechanism: Circular staplers often have safety features to ensure proper alignment and prevent accidental firing. These may include locking mechanisms, visual indicators, or audible cues.
Traction Mechanism (optional): Some circular staplers have a built-in traction mechanism that allows for better control and manipulation of the tissue during the anastomosis procedure.
It's important to note that the specific design and features of circular staplers may vary among different manufacturers and models. Surgeons and operating room staff should be familiar with the specific circular stapler they are using and follow the manufacturer's instructions for proper usage and maintenance. Additionally, proper training and expertise are required to safely and effectively use circular staplers for colorectal anastomosis.
