Cautions for endoscopic instruments
The width of the opening is large, which is suitable for hemostasis with a disposable deformable titanium clip when the blood vessel is bleeding. During the disinfection and maintenance, due to attention to the opening of the front section, long-term use has caused the titanium clip to bite tightly or cross bifurcation, and should be scrapped in due time.
Long-term use causes the head end to be more difficult to detach after being clamped, and the violent drag and pull causes the pipeline to rupture. Should be scrapped and replaced in due course. Attention should be paid to the operator's operation site when loading the clip. If the surgeon disconnects the distal end of the clip, the groove should face the distal end (the clip at the tip of the clip still faces outward).
Among the most frequently used instruments in endoscopic instruments, the loss is serious. The polyethylene material in the white part of the head end is often caused by high temperature electrocautery during operation and the inevitable abrasion of this part when disinfecting and cleaning the metal L part, resulting in too many exposed metal parts, which will cause electrocautery of non-operational parts during the operation. Should be promptly checked and reported for replacement.
The elastic potential energy is provided by bending the metal sheet at the handle. Because of its large grasping force at the head end, it damages the tissue, so it only grasps the tissue and organs that need to be removed, and is most commonly used in laparoscopy. Before use, check whether the metal sheet of the handle and the conductive wire are firmly inserted. When cleaning, pay attention to whether there is any residual tissue in the serrations on the head.
Because the teeth of the head are not damaged, and the effective area of the bite area is large, the pressure is small, so it is not easy to cause tissue damage. Mostly used to clamp and lift the stomach and intestines. However, if violent bite or excessive pulling, it can also bluntly damage the tissue, and attention should be paid when using it.
Commonly used for biting and pulling tissues, the serrations on the head can be damaged, but because the joints of the handle can rotate, it is more flexible than the elastic pliers. However, it requires continuous force after the occlusion, which is not as easy as the elastic pliers.
The head end is bent and there is no damage to the bite. It is often used for lifting, pushing, and blunt separation. It has wider application range than separating pliers and flat-nose pliers. However, since there is no damage to the saw teeth, the static friction is insufficient after occlusion, and the pulling effect is limited.
Commonly used for blunt separation and clamping of delicate parts. The bite is tight, and the saw teeth are damaged. Pay attention to the operation parts when using. Long-term use, the head bite is not precise, and hemostasis cannot be stopped during the operation. When disinfecting and cleaning, it should be reported and replaced in time. The power cord can be connected to the handle, but the principle of conduction is still unipolar, so use caution to avoid electrical conduction damage.
Long-term use causes head-end joint problems, the cutting is not tight, it can not be cut smoothly, or can not be smoothly opened. If it is found during the operation, it should be marked immediately. When disinfection and cleaning, it should be reported to the repair in time.
The head is retracted elastically to facilitate puncture. Before use, check whether the head is stuck or unable to retract. Check whether the switch at the pneumoperitoneum tube is loose or leaking.
Before use, check whether the joint at the valve is tight and whether the rubber cap is cracked to cause air leakage. The valve at the pneumoperitoneum junction should be closed before handing it to the operator.
When using, be careful not to put the pneumoperitoneum needle under the bed (otherwise you need to open the package separately). When disinfecting and cleaning, pay attention to whether there is foreign matter at the outlet, and whether there are any components of the pneumoperitoneum. Rubber pipes will aging and crack for a long time, so please check carefully before packing.
An extremely precious and easily damaged soft pipe in endoscopic instruments. The interior is composed of optical fibers, which often accelerate damage due to violent use, clamping, stretching and other improper operations. In the case of using the principle of sterility, the connection unit should be handed to the traveling nurse instead of being thrown on the ground, causing collision and wear. When binding and fixing the light source line, sufficient space should be reserved to avoid the deformation of the lumen as much as possible. Do not use violent operation when disinfecting and wiping the lens, and treat it gently.
