Surgical staplers are generally made of plastic and loaded with a disposable cartridge of surgical staples. The staplers come in both reusable and disposable models. They resemble construction or industrial staplers and are designed to insert and close several staples at once.

The devices may be used internally to seal tissue during surgery. They are useful in minimally invasive surgery because they require only a narrow opening and can quickly cut and seal tissue and blood vessels. Skin staplers are used externally to close skin under high tension, such as on the skull or the trunk of the body.
Surgical staples offer several advantages over sutures.
Surgical staplers are frequently used to close incisions in the abdomen and uterus during Cesarean deliveries, or C-sections, since the staples allow women to heal faster and reduce scar tissue. Surgeons may also rely on surgical staplers when removing part of an organ or cutting through organs and tissue inside the body.
They are also used to connect or reconnect internal organs within an organ system. The devices are frequently used for surgeries involving the digestive tract, including the esophagus, stomach and intestines, in which a portion of these tube-like structures have been removed and the remaining portions must be reconnected.
Patients must pay special attention to medical staples in the skin to avoid infection. A study reviewed the surgical site infection rate of wound closure using staples versus sutures in elective knee and hip arthroplasties. The researchers found a significantly higher risk of surgical site infection in patients with staples compared to sutures.
Always follow your doctor’s instructions and do not remove any dressings until it’s safe to do so. Rinse the site twice daily to keep it clean. Your doctor will tell you how and when to dress the wound to prevent infection.
When to Call Your Doctor About Surgical Staple Complications
Surgical staples usually remain in place for one to two weeks, depending on the type of surgery and the placement of the staples. In some cases, internal staples may not be removed. They are either absorbed or become permanent additions to hold internal tissue together.
Removing surgical staples from the skin is generally not painful. But they should be removed only by a doctor. Never attempt to remove surgical staples on your own.
Removal requires a sterile setting and a specialized surgical staple remover or extractor. The device spreads one staple at a time, allowing the doctor to gently work it out of the skin.
Usually, a doctor will remove every other staple, and a second appointment is scheduled to remove the rest if the wound has not completely healed.
Surgical staplers work by compressing tissue, connecting two pieces of tissue with staggered rows of B- shaped surgical staples and, in some models, cutting away excess tissue to create a clean closure of the surgical wound.
There are various designs for different types of surgeries, with most categorized as either linear or circular.
When using linear staplers, the surgeon uses the handles at one end to close the “jaws” of the stapler at the other end over the tissue. When the surgeon fires the stapler, a row of staples binds the tissue together and a blade cuts the tissue between the staples. The process seals the open wound to prevent bleeding.
Linear staplers are used to connect tissue during minimally invasive surgeries or to remove an organ. Circular staplers are often used for surgeries involving the digestive tract from the throat to the colon.
Circular staplers fire two staggered rows of staples from a circular cartridge. This circular layout allows the stapler to connect two sections of the intestine, or another tube-like structure, after a portion has been removed. The staples cause tissue to pinch up as rings or donuts between the staples. A built-in blade then slices off the overlaying tissue, sealing the new connection.
Surgeons watch the closed wound for about 30 seconds to make sure the tissue has been squeezed together properly and confirm that there is no bleeding.
Common materials for surgical staples include stainless steel and titanium. These are both strong metals that tend to cause few problems for patients in surgical procedures.
But plastic staples are frequently used for people with metal allergies or to reduce scar tissue.
Staples made from plastic or metals don’t dissolve like many sutures, so extra attention must be paid to prevent infection.
Staples made from polylactide-polyglycolide copolymer are designed to be reabsorbed into the body. They are often used in cosmetic surgery because, like plastic staples, they result in less scaring.
Johnson and Johnson’s Ethicon division and Medtronic are the two largest surgical stapler manufacturers. Together, they produced about 80 percent of the stapler market in , according to an analysis by Future Market Insights. 3M also manufacturers skin staplers sold in the United States.
The devices accounted for close to $2 billion in revenue for manufacturers in , with most sold in North America.

Surgical Stapler Manufacturers and Select BrandsJohnson & Johnson subsidiary Ethicon recalled 92,496 surgical staplers in April over concerns that they might not fire with enough force to completely form staples.
The U.S. Food and Drug Administration branded the recall as a Class I recall, the FDA’s most serious type. The agency warned in a statement that the devices could cause serious injuries or death. Some people who have been injured by malfunctioning devices have suffered serious injuries and filed surgical stapler lawsuits.
The recall affected two models of the company’s Endo-Surgery Intraluminal Staplers used in gastrointestinal tract surgeries.
Ethicon reported that two patients had been injured by the devices, according to the FDA. In both cases, the devices misfired, cutting portions of the rectum. Misfires or other malfunctions can prolong operations or require doctors to perform unplanned surgery to correct the damage.
The FDA warned that the misfires could increase complications from surgical staplers, including the risk for bleeding, infection, permanent damage to organs.
In , Ethicon recalled 6,744 Endopath Echelon Flex Powered Vascular Staplers with Advanced Placement Tip and White Reloads. The devices were used in gynecologic, urologic, thoracic, pediatric and general minimally invasive surgeries.
The company reported that an inspection had found the surgical staplers’ cartridges may not insert a complete line of staples when fired.
Medtronic issued two recalls of its Endo GIA staplers and staple cartridges from select production lots, or batches, in and . Both recalls involved possible missing components. The company said the defects could affect staple alignment and lead to serious complications.
At least five people were injured by staplers included in the recall, according to the company. The recall involved defects in staple cartridges that were spotted during the manufacturing process. The company reported “no confirmed complaints” about the devices from doctors or patients.
The U.S. Food and Drug Administration began tightening restrictions and reporting safety concerns over surgical staplers in . It issued new guidance for using the devices to doctors and hospitals, took steps to reclassify certain surgical staplers from low- to moderate-risk devices and reported tens of thousands of previously unknown cases of stapler malfunctions and injuries.
The new classification would require premarket review and clearance of the devices from the FDA before manufacturers could sell them.
The FDA actions followed a series of surgical stapler problems coming to light earlier in . Kaiser Health News reported that more than half of all surgical stapler malfunctions from through , 56,000 of them, had been reported to a hidden FDA database instead of a database accessible by the public.
The FDA consolidated the two databases so all the reports could be viewed by the public. The total number of reported surgical stapler malfunctions over the eight-year period rose from 41,000 to nearly 110,000.
Surgical staples are used to close the incision after surgery. In some cases, staples may be a better choice than stitches. Surgical staples do not dissolve as your incision or wound heals. For this reason, they require some special care and must be removed by your doctor after the incision heals.
Disposable Skin Stapler
When patients with lacerations come to your clinic, you must determine the appropriate method of closure-skin adhesive, sutures, or staples. Once you are familiar with bookbinding, you want to bind it very much. Everything is fine. Although bookbinding is fast and easy, please choose your closing method carefully. Suture the wound that is most suitable for the scalp, abdomen, back or limbs. Wounds on the hands, feet, face and neck should not be stitched.
Once you have determined that the laceration is suitable for suture and nailing, please clean the wound thoroughly. Carefully check the wound for signs of foreign bodies and other complications. Anesthetize the area with anesthetics such as lidocaine. If the wound is small, you can choose not to numb the area, because placing one or two staples may be more painful than anesthetic administration. You can also consider using a local anesthetic, such as EMLA cream.
Approach the edge of the wound with unaccustomed hands or tweezers. Align the center of the tear with the center of the stapler head. Press hard on the tear. The depth of staple placement depends on how hard you press the stapler device on the skin. Squeeze the handle or activator on the stapler and insert the staple into the skin. It's that easy. Continue to place staples about 3 to 5 mm apart until the wound is completely closed.
Surgical staples need to be retained for several days or up to 21 days (in some cases) before they can be removed.
How long your staples must be retained depends largely on where they are placed and other factors, such as:
The size and direction of the incision.
The type of surgery you have received.
The complexity or severity of your incision or wound.
How fast does the area heal?
Several indicators that your surgical suture staple may be ready to remove include:
The area has healed so well that staples are no longer needed and the wound will not be reopened.
There is no discharge of pus, fluid or blood from the area.
There are no symptoms of infection.
Disposable Skin Plasters
After you have obtained the staple, the following steps will help keep it clean as you heal:
Follow all the doctor's postoperative instructions.
Do not remove any dressings or bandages until your doctor says it is safe.
Rinse the area gently with clean water twice a day.
Use Vaseline or Vaseline and sterile bandages that will not stick to the area.
Change the bandage at least once a day or get dirty or wet each time.
Some common surgical suture staples materials include:
Titanium. It is well known that titanium adheres easily to body tissues and bones and is unlikely to cause inflammation or infection.
Plastic. You can use this material if you are allergic to metal in other surgical suture nails.
Stainless steel. Plastic is usually used for staples and may help reduce the appearance of scars from trusted sources.
Poly (lactide)-poly (glycolide) copolymer. This material is easily reabsorbed by the body and is very popular in plastic surgery.
Staples on the scalp are usually removed in about 7 days, while staples on the back, abdomen and limbs take 10 days to remove. To remove skin staples, use the skin staple removal tool. Place both edges of the tool under the staple and press it against the skin. Squeeze the handle of the tool until it is completely closed and lift the staple from the skin.
