Customized Metal Products-Upper And Lower Retainer

The upper and lower fixator of endoscopic stapler plays a vital role in minimally invasive surgery and is the hero behind the scenes to ensure the accuracy and smooth operation.

The core function of the upper fixture is to provide stable support and precise positioning for the upper components of the stapler. It closely fits the nail bin to ensure that the position of the nail bin does not deviate during the whole process of loading, transportation and firing of the nail. Imagine that if the nail bin is slightly shaken during the operation, the injection Angle and embedding position of the fitting nail will be out of control, and the upper fixing piece will firmly "lock" the nail bin through the card slot, screws or clips, so that it can maintain an accurate relative position relationship with the nail pushing device. This allows each push to be carried out accurately and stably, ensuring that the anastomosing nail is embedded in the tissue according to the predetermined trajectory, and achieving a tight and reliable stitching effect.

The lower fixer focuses on "escorting" the key components at the bottom of the stapler. It is closely connected with the nail base, the nail base as a key part of the receiving of the matching nail, in the process of striking the need to bear a huge impact, the lower fixed plate to provide a solid bottom support force to prevent the nail base in the force displacement, deformation. At the same time, the lower fixing plate also works with the power transmission parts to ensure that the force from the power source can act evenly and stably on the nail base, ensure the consistency of the force when the nail is struck, and avoid problems such as tissue suture and bleeding caused by uneven strength.

The upper and lower fixers cooperate with each other, the upper fixer controls the accurate operation of the upper part, and the lower fixer ensures the stable force of the lower part. Together, they build a stable "operating framework" for the endoscopic stapler, so that the doctor can confidently control the stapler in the complex environment of endoscopic surgery, successfully complete the cutting and stitching of the tissue, and lay a solid foundation for the rapid recovery of the patient.

Product Description

The upper and lower fixed plate of the endoscope stapler is the key structure to ensure the stable operation and accurate operation of the stapler.

In terms of material, high-strength medical stainless steel or engineering plastics with excellent mechanical properties are often used. Medical stainless steel is resistant to frequent forces and friction during surgery, as well as complex human fluid environment, to ensure that the fixed piece is stable for a long time, no deformation, no corrosion; With its light weight and high molding accuracy, engineering plastics not only reduce the overall weight of the instrument, convenient for doctors to control, but also achieve complex and fine structural design, and accurately adapt the stapler components.

Its structure design is exquisite and reasonable. The upper fixing plate is usually closely connected with the key components of the upper part of the stapler, such as the nail bin, the nail pushing device, etc., and is fastened by the clip slot, clip or screw to ensure that these parts do not shift during the firing process; The lower fixing plate is firmly combined with the nail holder and related transmission components to provide solid support for the firing of the matching nail. The synergistic effect of the two enables the stapler to maintain accurate positioning in the narrow space of endoscopic surgery, so that doctors can smoothly and accurately complete the tissue cutting and suture, which is an important basis for the successful implementation of endoscopic surgery.
