Electric endoscopic stapler nail bin is a key consumable in modern minimally invasive surgery and plays an important role in the successful implementation of surgery.
From the appearance, it is generally in a long strip shape, and the size is designed to fit the main body of the electric endoscope stapler, which is convenient for the doctor to operate flexibly under the narrow field of view of the endoscope. The shell is mostly made of high-strength medical plastic, which not only has excellent insulation properties, effectively shields electromagnetic interference in the surgical environment, and ensures stable operation of the equipment, but also has good durability and can withstand repeated disinfection and minor collisions during surgery.
The core components are anastomosis nail and cutting blade. Anastomotic nails are mostly made of medical titanium alloy material with excellent biocompatibility, which can minimize the rejection reaction of human tissue and ensure long-term stable fixation of tissue. According to different surgical sites and tissue characteristics, such as gastrointestinal surgery, lung surgery, urology surgery, anastomotic nails have a variety of sizes and shapes. Gastrointestinal surgery may require long pins and tightly packed anastomotic nails to prevent leakage of digestive fluid. Lung surgery focuses on thinner, higher-fitting spikes to accommodate delicate lung tissue. The cutting blade is usually hidden behind the anastomosis nail, made of sharp and tough medical stainless steel, and the blade is extremely sharp, which can cut off the excess tissue cleanly during the operation, and the cutting trajectory is precisely matched with the hitting path of the anastomosis nail, so that the cutting and anastomosis can be completed simultaneously, effectively shortening the surgical time.
Working principle, in the process of electric endoscopic surgery, when the doctor controls the stapler close to the tissue to be anastomosed, press the electric control button, and the powerful electric drive system will start immediately. On the one hand, the anastomosed nail is driven by the power generated by the motor, and is shot from the bottom of the nail bin at a high speed, accurately penetrating the two layers of tissue to be anastomosed, and then bending into a specific shape with its own elasticity or with the help of an auxiliary forming device, and the tissue is firmly fixed, as efficient as stapling paper. At the same time, the cutting blade is quickly started according to the preset route to remove the excess tissue, making the edge of the anastomosis site neat, creating an ideal condition for postoperative tissue healing.
