A Comprehensive Guide to the Surgical Stapler Structure in Stapler Surgery

Introducing the easyEndo™ Lite Series by EziSurg Medical

Modern surgical staplers rely on a precise stapler mechanism that controls tissue compression, staple formation, and firing safety. Understanding this mechanism helps surgeons evaluate different stapler types, including linear staplers, endocutters, and circular staplers.

Surgical staplers are vital instruments in modern minimally invasive procedures, surgical stapling procedures and stapler surgery. The easyEndo™ Lite Series by EziSurg Medical represents the cutting edge in surgical technology, combining precision engineering with ergonomic design to enhance surgical outcomes and improve patient safety. This article provides an in-depth look at the structure of our surgical stapler, detailing each component and its role in delivering reliable performance.

1. Overview of the Surgical Stapler Structure

The stapler mechanism typically consists of three coordinated systems:

• Tissue compression system – ensures stable pressure before firing

• Firing and knife system – delivers staples and completes the cut (for endocutters)

• Locking and safety mechanism – prevents accidental firing

These systems allow a surgical stapler to create uniform staple formation while maintaining tissue perfusion.

The surgical stapler, a common operation stapler, is designed to deliver consistent, reliable tissue approximation and anastomosis. Its sophisticated design integrates multiple components that work together seamlessly. Below is a breakdown of the main parts:

Surgical Stapler Components

1.Cartridge

The staple cartridge is inserted into the cartridge. This secure fitting ensures that the staples are accurately aligned for proper deployment.

2.Anvil

The anvil is a critical component that collaborates with the cartridge to form the staples correctly. It provides the counterforce needed for the staple to close securely around the tissue.

3.Double Articulating Joint

This feature allows for enhanced maneuverability and access, particularly in confined surgical fields. The dual joints facilitate a wide range of motion, ensuring optimal positioning during procedures.

4.Instrument Shaft

The instrument shaft serves as the stapler's backbone, extending the tool’s reach into deep or hard-to-access areas while maintaining rigidity and control.

5.Rotating Knob

The rotating knob offers fine-tuned adjustments during surgery. It enables precise alignment of the stapler, ensuring that the staples are deployed at the exact desired location.

6.Firing Trigger

The firing trigger activates the stapling mechanism. Designed for intuitive operation, it ensures that the firing process is both smooth and controlled.

7.Speedometer

An integrated speedometer monitors the stapling speed. This feature helps maintain consistency in staple deployment, contributing to a more predictable and safe outcome.

8.Return Knob

The return knob assists in retracting the stapler mechanism after firing, preparing the device for the subsequent use without additional manual adjustments.

9.Reset Button

The reset button is essential for restoring the stapler’s mechanism to its initial state after close the jaw, ensuring the device is ready for subsequent applications.

10.Handle

The ergonomic handle provides a comfortable grip and precise control, reducing hand fatigue and increasing accuracy during lengthy procedures.

11.Safety

Built-in safety features prevent accidental activation, thereby protecting both the patient and the surgical team. These safeguards are integrated throughout the device’s design.

12.Rotation Collar

The rotation collar enables controlled rotation of the stapler, ensuring optimal placement and alignment of the instrument even in challenging surgical environments.

2. Cartridge Structure

Equally crucial to the stapler’s function is its cartridge structure, which holds the staples used in the surgical procedure.

Cartridge Components

1.Protective Cap

The protective cap shields the cartridge from damage and contamination during storage and transport, ensuring that the staples remain sterile until use.

2.Cartridge

The cartridge contains the actual staples that will be deployed during the procedure. It is designed for secure placement within the cartridge to guarantee consistent performance.
