1. Pneumoperitoneum instability
Unstable pneumoperitoneum pressure causes instability in the pneumoperitoneum space, especially in narrow cavities (e.g. transanal surgery)
High pneumoperitoneum pressure, patients with surgical pain. It can lead to common complications of pneumoperitoneum, such as subcutaneous emphysema, hypercapnia and acidosis, carbon dioxide gas embolism, and also pneumothorax or mediastinal emphysema, which can sometimes cause cardiac arrhythmia.
2. Surgical smoke obscuration and its hazards
Smoke obscures the surgical field, which makes it difficult to see or see through.
Smoke filled lens is easy to fog up, need to frequently wipe the mirror and suction and exhaust smoke, reduce the efficiency of the operation.
Exhausted surgical smoke may contain active viruses and other hazardous substances, posing infection risks and long-term occupational hazards to healthcare workers.
3. The operation is not simple, need to connect multiple devices and pipelines, the operation is more cumbersome.
4. Small flow rate and can only output dry cold gas, which may cause postoperative pain and other damages to patients.
5. Large size, can not be placed in the trolley smoothly.
