The technical scheme of the invention has the following substantial technical effects and the realization process thereof: A. the technical problem to be solved is that even the existing DaVinci surgical robot needs skilled operation and artificial skill of doctors for operation, and the patent creatively utilizes images, distances and three-dimensional modeling to carry out accurate position control; B. the method can utilize image analysis and data analysis to show the key position of the price on the image, judge the distance and the position between the operation part and the part at any time and give an alarm; D. in complex body cavities and organs, such as a complex internal environment of a kidney, the accurate positioning is realized, so that part of stones and the like cannot be lost due to operative field, and the operation cannot be lost.

When the operation part is a laparoscope, the mirror directly runs in the ureter, and once the pipeline of the mirror gradually approaches the boundary of the safe area, an alarm is given; when the surgical operation arm is close to a safe area in the case of the DaVinci surgical robot, the voice reminds the important part to be close and the operation is noticed. The technical scheme of the invention has the following substantial technical effects and the realization process: because the human body structure is complicated, doctors feel more attentive, and important parts can be warned through voice prompt.

As a further preference, when the operating head enters the safe area, the central control system forcibly halts the inquiry as to whether to continue, for example, in fig. 5, when the operating section is sufficiently close to the safe area 8, the robot arm movement is forcibly stopped, the display interface inquires whether to confirm the continuation of the operation, the operation right is given to the human, and at the same time, the forcible damage prevention confirmation is performed, and the method encounters an operation accident such as an aorta.

The method also comprises a judging mode of the emergency situation of the operative field, and comprises the steps that a large number of red areas appear suddenly in the image or video automatic analysis early warning part, so that the judgment that the area is possibly a large bleeding is made, a warning is given, and the warning mode is a voice alarm or a sound-light alarm. The technical scheme of the invention has the following substantial technical effects and the realization process: the original technology is not realized in the mode at all, and the image or video automatic analysis early warning part adopts the image analysis mode. Image analysis is of course a well established art including, but not limited to, color analysis, pixel analysis, color analysis, pixel separation techniques, and the like. The judgment here is that a large number of red pixels appear suddenly in the operative field, and it is judged that a large bleeding is likely. Avoid misjudgment of doctors.

The operation part is attached with a contrast agent sealing pipeline, and the contrast agent is irregularly determined by a contrast device in the operation to assist in determining the position of the operation head. The technical scheme of the invention has the following substantial technical effects and the realization process: with reference to fig. 6 and 7, the contrast agent can determine the distance even when the arm is operated by sealing, and it should be noted that this determination method is an aid for verifying the distance through multiple channels.
