The endoscopic linear stapler is a device used in medicine as an alternative to manual suturing. The main principle of operation is to dissociate or anastomose tissue using titanium staples, similar to a stapler.

Depending on the scope of application, they are mainly divided into skin anastomoses, circular anastomoses for the digestive tract (esophagus, gastrointestinal, etc.), rectal anastomoses, circular hemorrhoid anastomoses, circumcision anastomoses, vascular anastomoses, hernia anastomoses, and pulmonary excision sutures.

The following diagram describes the definition and role of the endoscopic linear stapler.

Role of endoscopic linear stapler


When performing surgery, cutting and anastomosis must be performed. Anastomosis includes connecting two usually dispersed or not directly connected cavity structures, and the two tissues may have different thickness and biomechanical properties. The stapler aims to overcome these differences and make the operation complete smoothly.

Different tissues have different properties. Different staplers, staples and nail bins are suitable for different types of surgery.


Definition of endoscopic linear stapler


1, endoscopic linear stapler has different types, linear, curved or ring-shaped, disposable and reusable.

2, anastomotic staples are also made of a variety of materials, such as titanium, stainless steel or absorbable synthetic materials with weak immune response.

3, nail position according to the characteristics of the anastomotic nail by color classification.

Each endoscopic linear stapler model has features adapted to the specific situation.


Characteristics of endoscopic linear stapler


1. the endoscopic linear stapler has anastomosing nails in one row or in two staggered rows, in three different sizes, with anastomosing nail sizes between 4.5 and 5.5 mm.

2. endoscopic linear stapler with four rows of anastomosing nails and a thin plate driven by a cursor, with three sizes of anastomosing nails with different heights and lengths.

3. the arc-cut anastomosis with four rows of anastomotic staples has only one curved incision of four different diameters.

4. the circumferential anastomosis clutch can form a circumferential line of staples ranging from 21-33 mm in diameter.

Each type of endoscopic linear stapler has its own matching staple compartment, in which the height of the anastomotic staple varies. The most important factor in the anastomotic staple is the closure staple height, as it must be ensured that it can accommodate the associated tissue during closure.


When selecting a endoscopic linear stapler, the following characteristics must be noted.


Characteristics of endoscopic linear stapler


1、Be able to reach the target area


2、Can complete stitching line and cutting


3、Avoid stitching line leakage and bleeding
