The upper cover is a key component of the endoscopic stapler and plays an indispensable role in the surgical process.
In terms of material, medical grade stainless steel or high-performance engineering plastics are used. Medical stainless steel has excellent strength and corrosion resistance, can resist body fluid erosion in the surgical environment, instrument friction, long-term maintenance of structural stability; Engineering plastics with its light weight, convenient molding characteristics, reduce the overall weight of the instrument, convenient for doctors to operate, and can achieve complex and fine structural design to meet the needs of precision medicine.
Its structural design is exquisite and complex. The shape accurately fits the main body of the nail seat, closely fits to ensure seamless docking and prevent tissue fluid and impurities from penetrating into the internal precision structure. The surface of the upper cover has a permanent anti-slip texture or special marks to assist the doctor to hold and position, and improve the accuracy of operation. Some products also have built-in cushioning and shock absorbing structures, which absorb and disperse the impact force at the moment of the nail strike, ensure the overall stability of the nail holder, and avoid the displacement and deformation of the parts caused by the impact, thus affecting the surgical effect.
