Medical staplers and staples are medical devices that can replace sutures. They can close large wounds or incisions more quickly and cause patients less pain than sutures. They are often used in minimally invasive surgeries. They may also be used to close wounds in areas where the skin is pressed against the bone, and during surgeries to remove organs or reattach parts of internal organs.

Surgical staplers are usually made of plastic and contain disposable surgical staple cartridges. Staplers come in both reusable and disposable models. They are similar to construction or industrial staplers and are designed to insert and close multiple staples at once.

The device can be used to seal tissue internally during surgery. They are useful in minimally invasive surgery, helping surgeons reduce uncertainty and improve anastomotic performance in general, bariatric, thoracic and colorectal surgery.

Medical staplers have several significant advantages:

◆Fast: The stapler can connect tissues quickly and effectively, reducing surgical time compared to traditional manual suturing.

◆Consistency: The stapler provides a consistent anastomosis, reducing human error and helping to ensure a strong and stable connection.

◆Reduce Bleeding: The use of medical staplers can reduce the risk of bleeding during surgery because they can achieve hemostasis in the tissue while stapling.

◆Reduces the risk of infection: Staplers can reduce the exposure time of the surgical wound, thereby reducing the risk of infection.

◆Suitable for minimally invasive surgeries: For minimally invasive or laparoscopic surgeries, medical staplers are especially useful because they can complete the stapling work in a smaller space.

◆Improve surgical efficiency: The use of staplers can improve the efficiency of surgery, allowing doctors to complete more stapling tasks in a shorter period of time.

The principle of medical stapler is based on the concept of mechanical anastomosis, which completes the connection of tissues through a series of cleverly designed mechanical structures. The following is the working principle of general medical staplers:

●Opening and positioning: At the beginning of the surgery, the doctor will use the stapler to open it and accurately position it on the tissue site that needs to be stapled.

●Clamping the tissue: There are clamps on both sides of the stapler, which are responsible for clamping the tissue and ensuring the stability of the tissue during the anastomosis process.

●Cutting and hole-forming: Some staplers have cutting blades or hole-forming features to cut or pass through tissue while stapling.

●Staples: A stapler places one or more rows of metal staples (staples) between the tissues. The staples pass through the tissues and connect them tightly together.

●Cut off excess parts: Some staplers also have a scissor function, which is used to cut off excess nail parts to ensure a smooth and neat anastomosis.

The entire process is usually completed by the surgeon by operating the handle or control device of the stapler. The design of medical staplers can vary based on specific surgical needs and site of anastomosis. This mechanical anastomosis method can improve surgical efficiency and reduce surgical time compared with traditional manual suturing.
