[0002] Urological robotic surgery is a minimally invasive surgical technique that uses a robot-assisted system to perform urological surgery. This technique combines high-tech robotic systems with the professional skills of surgeons to improve the precision, accuracy and safety of surgery. In urological surgery, the robotic system is usually composed of one or more robotic arms, surgical instruments and cameras, which are operated by the surgeon through a console. The surgical instruments and cameras are inserted into the patient's body through tiny incisions, and the robotic system performs surgical operations through these instruments. The head curved aspirator of urological robotic surgery plays an important role in urological surgery. It can be used to assist in operations, tissue processing, aspirate secretions or fluids, and keep the surgical area clean.
