*4.1.2 Patient console*

The patient console is the executive part of the remote surgical robot system to implement minimally invasive surgery. Its main structure is to provide support for two patient manipulators and one image arm. In the process of remote surgery, the surgical assistant is also required to work next to the patient operating table in the sterile area, responsible for replacing the surgical instruments and threedimensional laparoscopy, and assisting the chief surgeon to complete the operation. The operation of the remote surgical robot system must always be under the absolute control of the chief surgeon or surgical assistant and meet a certain priority relationship, that is, the surgical assistant next to the patient's console has the highest priority, and they can adjust the robot's motion at any time according to the actual situation of the operation.

Similarly, the patient console also includes the slave communication control box, which is composed of industrial computer, display, image processor, keyboard, etc. At the slave operation end of remote surgery, the slave communication control box is connected with the patient console for use, receives all signals from the remote master operation end, and simultaneously sends all signals and three-dimensional images to the remote master operation end.

#### *4.1.3 3D endoscope camera system*

The three-dimensional endoscope camera system collects the three-dimensional images in the body cavity area and then presents the image data on the threedimensional display. During the operation, it is located outside the sterile area and can be operated by itinerant nurses, and various auxiliary surgical equipment can be placed. Three-dimensional laparoscopy is a high-resolution optical three-dimensional lens, which can magnify the surgical field by more than 10 times, and can obtain

three-dimensional high-definition images of the surgical field, so that the surgeon can get a clearer understanding of the structure, reduce visual fatigue, and improve the accuracy of surgery.
