what are the different types of surgical staplers

In surgical operations in hospitals, the most commonly used surgical instruments are basic surgical instruments, and surgical staplers are one of them. According to their different structural and functional characteristics, they are divided into many types. Being familiar with and mastering the use of various types of staplers is the most basic requirement for surgeons.

In the process of surgical suturing, the doctor's superb craftsmanship and handy tools are the key to the success of the entire operation. The stapler is a device used in surgery to replace manual suturing. The working principle is to use titanium nails to separate or staple tissues, similar to a stapler. According to different application scenarios, staplers are divided into linear surgical stapler, skin staplers, circular staplers, linear cutting staplers, laparoscopic staplers, etc.

linear surgical stapler

Although this type of stapler has only one function, it is widely used. It is mainly used for the closure of stumps such as bronchi, esophagus, stomach, duodenum, intestines, and blood vessels. Different models can be selected according to different tissues, but it should be noted that this type of stapler does not have a cutting function.

Circular (annular) stapler

For this type of stapler, it can be further divided into circular (anorectal) stapler and tubular (digestive tract) stapler according to the application. Circular (anorectal) stapler can be divided into: stapler PPH (hemorrhoidal mucosal circumcision anastomosis) and TST (open-loop minimally invasive hemorrhoidal stapler). The specific difference between the two is that TST is a selective stapler, a new technology developed on the basis of PPH procedure.

TST uses a special anorectal scope to form different open-loop windows, uses anastomotic probes to lock hemorrhoids, and adjusts the resection range of hemorrhoidal mucosa according to the size and amount of hemorrhoids, thereby protecting the normal function of the anus to the maximum extent.

linear cutting stapler

It has a larger opening and closing mouth, which is convenient for adjusting the position; a unique firing button, which is convenient for left and right operation; a full range of specifications, suitable for various surgeries; a patented cam design, easier operation; the same instrument can replace the needle cartridge suitable for tissues of different thicknesses.

laparoscopic stapler

The characteristics of this stapler are the curved stapler, which makes it more flexible to operate in a narrow surgical space; the equidistant gap control ensures that the distal and proximal ends of the tissue are consistent; it is equipped with a disposable safety device to avoid the secondary firing of the used stapler, ensuring the safety of the operation; the wide front opening of the stapler is convenient for tissue inclusion; the same instrument can be used with all types of staplers to reduce the complexity of the operation;

The laparoscopic stapler has a total of 6 rows of staples, and there are new blades in the stapler. While stapling, the blade cuts the tissue from the middle, so that 3 rows of staples on each side can complete the suturing and hemostasis functions; the stapler can rotate 360°, is designed with a manual release button, and adopts an ergonomic handle design, which can operate the entire firing process with one hand.

skin stapler

The disposable skin stapler is a surgical instrument used for surface skin suturing, which has the advantages of simple operation, fast suturing speed, and good postoperative incision healing. It has a comfortable feel and is suitable for doctors with different hand shapes. The body design is close to nature, and the surgical field of vision is good, which facilitates faster and more accurate skin suturing.

There are many types of staplers, and the above are just a few common ones. When purchasing stapler equipment, you need to communicate with the sales staff of stapler manufacturers to understand the application scenarios, and then recommend quotations based on the required size specifications. I hope that every consumer can buy satisfactory equipment.
