Although being more complex to operate and resulting in longer procedure times, in several studies covering gastric, bariatric, and colorectal surgery, linear staplers appeared to be preferred in clinical use due to their lower rate of anastomosis leakage and anastomosis strictures, with a sensible reduction in patients' postoperative morbidity [3; 4; 5; 6]. Regardless of its specific configuration, a surgical stapler is always characterized by an actuation handle: the surgeon can operate the device manually through a sequence of squeezing a handle or sliding a knob. The effective function of stapling, cutting, and ejecting the staples is performed by the loading unit: two jaws are coupled in different ways to act, one as a cartridge loader for the staples and the other as an anvil to allow the closing of the staples. In the case of circular staplers, the anvil jaw is detachable, granting its insertion into the anastomosis site. The actuation handle and the loading unit are usually connected to each other: the input from the surgeon is translated into the mechanical or electro-mechanical firing system through the use of various keyed shafts [7]. Additional pins can be inserted into the jaws or be comprised into the loading unit to serve as alignment or safety devices, ensuring the correct compression of the tissue before firing or avoiding retention after staple delivery. Each device is completely in accordance with the aims of surgical stapling, which consist, from a medical point of view, of creating an adequate lumen, preserving adequate vascularization, preventing tension in tissues, avoiding leakage, providing hemostasis, and ensuring mechanical reliability [8]. Non-absorbable staples are the ones most widely used in clinics thanks to their low artifact production in CT and their non-magnetic behavior, which causes minimal distortions in MRI. Titanium is the leading material, both pure or in alloys, thanks to its high resistance and lighter weight compared to stainless steel. Furthermore, titanium is corrosion-resistant but, most importantly, anti-allergic, and it can also be employed in patients suffering from chromate-nickel allergies [1; 9]. The general design of stapling devices includes an anvil, a cartridge assembly to support an array of staples, a mechanism to push the cartridge close to the anvil, an alignment pin for capturing tissue between the cartridge and the anvil, and a firing mechanism for ejecting the surgical staples. The firing process is guided by a sequence of pressing the handle: the first press grants tissue compression and allows the surgeon to verify the correct alignment of the jaws, while the second press releases the staples. A button placed on the stapler permits the opening of the jaws at the end of the operation, setting the tissue free and allowing the reloading process. The main particularity of cutting staplers is the addition of a blading element that allows for making a resection in the middle of the rows of staples. Instead, for endo cutting staplers, the instrument is composed of a disposable articulating end effector comprising the cartridge, the anvil, and a disposable handling unit containing the firing mechanism and the safety control system. The circular staplers have the same components with the particularity of a circular anvil and arrangement of the staples with a blading element. The powered stapling devices have the distinction of a powered actuation, meaning that the firing mechanism is controlled by an electro-mechanical system that gains energy from a battery. Figure 1 shows a description and representation of each type of device.
