First of all, let's learn about the development history of surgical staplers, one of the most important medical surgical instruments today.

As early as the early twentieth century, foreign experts started to develop the stapler, but due to the bulky instruments, and time-consuming loading and unloading, the large volume can not be used in clinical. With the continuous exploration and improvement of experts, the stapler is getting closer to clinical application.

The surgical stapler (Auto Suture) that was really widely used in the clinic was invented by the American Surgical Corporation (USSC) in the s. In , a brand new kind of surgical staplers, the Liner stapler TA (Thoracic-AbdominaI) was first introduced. Another new operation stapler, the Linear cutter GIA (Gastro-lntestin Anastomosis) was first introduced in . The EEA circular stapler (End-End Anastomosis) was first introduced in , and this new invention of the operation stapler created a milestone in the history of modern surgery. Then, in the late s, surgical stapler manufacturers in China's major cities including Jiangsu, Shanghai, Beijing, and Hangzhou have begun to design and manufacture gastrointestinal staplers. In the early s, the USSC (United States Surgical Corporation) of the United States introduced a new generation of disposable surgical plastic stapler, which has been widely used in clinical practice.

Basic Working Principle of Surgical Staplers

The working principle of various surgical staplers is similar to the book stitcher, so it is generally called STAPLER. It fires two or three rows of interlaced staples into the tissue to cross-stitch the tissue. The nail forming effect is good and it is B-shaped

The main components of the stapler are staples anvil, cartridge, staple driver, firing handle, positioning needle, knob, and marking ruler.

Types and Functions of Surgical Staplers:

NameFeaturesApplicationTA (Thoracic-AbdominaI)
Single Use Linear StapleStraight line suture tissue , can not be cut, need the operator to manually cutDigestive tract reconstruction and closure of stumps or incisions during liver resection.GIA (Gastro-lntestin Anastomosis)
Single Use Linear Cutting StapleThe cutting and stitching work can be completed at the same time; the larger opening helps to adjust the position; there are different types and lengths of staple cartridges, suitable for different needs.Various gastrointestinal, intestinal side-to-side anastomosis, split lung, partial lung resectionENDO GIA (Endoscopic Gastro-lntestin Anastomosis )
Single Use Endoscopic Linear Cutting StaplerIt is suitable for the operation of closing and cutting under the endoscope, and the reload can change the direction.Under gastroscopy, the gastrointestinal tract and the intestinal tract are closed, and side to side anastomosis and other operations.EEA (End-End Anastomosis)
Single Use Circular StaplerThere are many types of circular stapler. Choose according to the diameter of the intestinal tract during surgeryEnd-to-end anastomosis of gastrointestinal and esophageal surgery
