These are the questions we hear most often from surgeons, theatre teams and procurement staff. Each answer is short, with links to longer articles if you want more detail.
The Basics
What Is a Surgical Stapler?
A surgical stapler is an instrument that places rows of small metal staples to close, join or divide tissue. It is used in many specialities and often saves time compared with hand suturing. Read the full explanation in what is a surgical stapler.
What Is the Difference Between a Stapler and a Cutter?
A stapler or closer places staples only. A cutter places staple rows and divides the tissue between them with a blade, so the cut edge is already sealed.
What Is a Reload?
A reload is the replaceable cartridge that holds the staples, and in a cutter the blade, for an endoscopic stapler handle. Trizone and Tenzr reloads use different colour codes, explained in our article on reload colour codes.
Types and Selection
What Is the Difference Between Linear and Circular Staplers?
Linear staplers place straight rows. Circular staplers place a ring of staples and trim tissue inside it, creating a round join. See circular staplers and anastomosis.
How Do Open and Laparoscopic Staplers Differ?
Laparoscopic staplers pass through a trocar and usually articulate. Open staplers are designed for direct access. More in open vs laparoscopic staplers.
Are Powered Staplers Better?
The evidence is mixed. A 2023 meta-analysis reported benefits in some outcomes but not all, and called for higher-quality studies. See powered vs manual surgical staplers.
How Do I Choose a Stapler for My Hospital?
Start with your case mix, then compare staple formation, tissue control, documents, supply and total cost. Use our hospital checklist.
Reinforcement and Energy
What Is Staple Line Reinforcement?
It is an extra layer along the staple line, such as the bio-absorbable ZED strip made of SIS, used where tissue is thin, friable or under tension. Read why reinforcement matters.
What Does an Ultrasonic Energy Device Do?
It uses vibration to seal vessels and divide tissue without passing current through the patient. Learn more in ultrasonic energy systems in surgery.
More Questions Hospitals Ask
Can Staplers Be Reused?
Disposable staplers are designed for single use. Some systems use a long-life handle with single-use reloads. Always follow the instructions for use and your hospital’s reprocessing policy.
How Should Staplers Be Stored?
Store them in their original packaging, in a clean, dry area, within the temperature range printed on the pack, and use them before the expiry date.
What Should We Do If a Stapler Misfires?
Follow your hospital’s incident procedure, keep the device and packaging, record the batch number and report it to the supplier so the manufacturer can investigate.

Practical Questions From Theatre Teams
What Is Pre-Clamping?
Pre-clamping means closing the jaws on the tissue and waiting briefly before firing, so fluid can leave the tissue and the thickness settles. Some designs build this into the instrument, for example through staged compression.
What Is Gecko Claw Technology?
Gecko Claw is a gripping surface on certain FourZone reloads, such as Trizone GC and Sazo. It is designed to hold tissue against the pull of the jaw, so the tissue that was measured is the tissue that gets stapled.
Why Do Some Staplers Have Three Rows and Others Two?
A third staggered row adds redundancy and can reduce bleeding at the staple line. Whether it is needed depends on the procedure, the tissue and the surgeon. Examples include TRIAZO, C-Anazone-Tst and Pile F Tst.
What Is MAC?
MAC stands for minimal anastomotic clearance. It sets a minimum gap between anvil and cartridge in a circular stapler so that tissue cannot be over-compressed.
How Do I Know Which Reload to Choose?
Match the reload’s staple height to the compressed tissue thickness, following the instructions for use and the family’s colour code. If you are unsure, consult a senior colleague before firing.
Quality and Buying
What Quality Documents Should a Supplier Provide?
Typically a manufacturing licence or registration, a quality management certificate such as ISO 13485, instructions for use and any documents the tender requires. See what hospitals should ask.
Where Is FourZone Based?
FourZone Healthcare LLP is based in Ahmedabad, Gujarat, and supplies hospitals across India. Our focused stapling line is XYTE.
