This invention relates to an intraoperative nerve localization system for thoracic sympathectomy, belonging to the field of minimally invasive surgical assistance and medical information processing technology. During thoracoscopic surgery, this system identifies and analyzes candidate regions of the thoracic sympathetic nerve by acquiring intraoperative thoracoscopic images and patient physiological signals. It also verifies the sympathetic nerve properties of the target structure by combining the physiological functional responses induced by intraoperative nerve stimulation. Based on this, the system fuses and calculates the image structural information and functional response information to generate the localization reliability of the thoracic sympathetic nerve, providing the surgeon with localization references and safety prompts for thoracic sympathectomy. This system enables real-time, objective localization of the thoracic sympathetic nerve during surgery, reducing reliance on surgeon experience, lowering the risk of mis- or missed sympathectomy, and improving the safety and consistency of thoracic sympathectomy, thus possessing high clinical application value.

The present invention relates to a surgical assistance device with blood suction and tissue holding mechanisms having a ring-shaped circular structure. The structure has two extendable sections that allow the diameter to be increased or decreased. Rectangular prismatic hollow projections that do not have a front face are distributed equidistantly on the inner surface of the structure. The projections house holding clamps, the depth of which can be adjusted. The device of the present invention comprises a connector duct that is located on the surface of the outer face of the structure and runs along the inside of the structure, said duct being connected to an external suction system. Two suction pipes are positioned on the surface of the inner face of the structure, and they are inserted into the structure to connect to the connector duct. This configuration makes it possible to extract the blood that has accumulated in the area where the surgical assistance device with blood suction and tissue holding mechanisms is positioned.

This surgical assistance system provides a mechanism to prevent operator confusion caused by the robot arm moving in a direction different from the operator's intended direction when the operator moves the robot arm using a control tool. [Solution] The surgical support system 500 includes a pivot button 66 that stores in a storage unit 351 the pivot position PP which serves as the pivot point for the movement of the surgical instrument 1 attached to the robot arm 50, a joystick 62 for operating the movement of the surgical instrument 1 by the robot arm 50, and a first control device 310 that, when the surgical instrument 1 deviates from the pivot position PP stored in the storage unit 351, executes a return process to return the position of the robot arm 50 at a movement speed smaller than the movement speed of the robot arm 50 moved by the operation of the joystick 62 so that the surgical instrument 1 passes through the pivot position PP.

The present application relates to the medical technical field, specifically relates to a kind of surgical auxiliary method, device, equipment and medium, method includes: obtaining the sign information of patient in operation, wound information, surgical progress information and surgical environment information;The sign information, wound information, surgical progress information, surgical environment information and the historical case and surgical plan of the patient are input into the first risk prediction model of pre-set to carry out sudden risk prediction, and the first risk prediction model is used to predict whether patient exists sudden risk;The first risk prediction model outputs first risk prompt.The present application can accurately predict the sudden risk that patient can appear in operation, and timely risk prompt is sent to surgeon, so that doctor can take measures in advance according to prompt to reduce or avoid risk, and then improve surgical safety and surgical efficiency.

This invention, in the field of surgical assistance technology, discloses an individualized surgical pathway planning system based on a digital model of brain functional areas and lesions. The invention aims to address the technical problems of existing surgical pathway planning processes relying on subjective experience and lacking a quantitative evaluation system. This invention constructs an individualized brain tissue model including physical attributes and functional risk indices by analyzing patient imaging data; based on this model, candidate surgical pathways are generated, and these pathways are then subjected to multi-dimensional quantitative evaluation and screening, combined with clinical preference weights to determine the optimal surgical pathway recommendation; simultaneously, intraoperative monitoring data is compared and verified with preoperative planning, and deviation information is recorded to optimize subsequent planning. This invention provides a systematic quantitative decision-making basis for surgical pathway selection, offers balanced decision support reflecting surgical strategies, and establishes a postoperative verification and recording mechanism.
