1. A breast prosthesis processing system, comprising: a scanner, a data processing device, a breast prosthesis processing device, and a printing device;
the scanner is electrically connected to the data processing device, and the data processing device is electrically connected to the breast prosthesis processing device and the printing device;
the scanner is configured to scan a human body to obtain a body scan image and transmit the body scan image to the data processing device, wherein the body scan image includes a scan image of a torso, and the scan image of the torso comprises an image of a normal breast and an image of a residual part after mastectomy;
the data processing device is configured to, in response to a first input, mark feature points on the image of the residual part after mastectomy; mirror the feature points to obtain mirrored feature points; generate model data of an excised breast based on the mirrored feature points and the image of the normal breast, and transmit the model data of the excised breast to the breast prosthesis processing device and the printing device;
the breast prosthesis processing device comprises a processor, a first actuator, and a container, wherein the processor is electrically connected to the data processing device and the first actuator, and the processor is configured to control the first actuator based on the model data to drive the container to rotate, thereby forming a breast prosthesis model from silicone within the container;
the printing device comprises a controller, a nozzle, and a fixing base, wherein the fixing base is configured to secure the breast prosthesis model, the controller is electrically connected to the data processing device and the nozzle, and the controller is configured to control the nozzle to spray pigment onto the breast prosthesis model based on the model data;
wherein the printing device further comprises a robotic arm, a distance measurement module, and an optical sensor module, wherein the robotic arm, the distance measurement module, the optical sensor module, and the nozzle are electrically connected to the controller, and the nozzle, the distance measurement module, and the optical sensor module are mounted on the robotic arm, with the nozzle, the distance measurement module, and the optical sensor module positioned on the robotic arm; and the distance measurement module is configured to detect a distance between the nozzle and the breast prosthesis model; and
the controller is configured to control a movement of the robotic arm to drive the optical sensor module, enabling the optical sensor module to determine a working surface for the nozzle, wherein the working surface is a curved surface at a predetermined distance from a surface of the breast prosthesis model and conforming to a surface shape of the breast prosthesis model; based on the working surface, control the movement of the robotic arm to drive the nozzle and the distance measurement module, and determine a target distance between the nozzle and the breast prosthesis model based on the distance measurement module; and control the nozzle to spray pigment onto the breast prosthesis model based on the model data, the working surface, and the target distance.
