The operating table with the temperature control function comprises a bed frame, the bed frame at least comprises a head pillow section, a back pillow section and a leg pillow section, each area is provided with a first temperature sensor for monitoring the temperature and a temperature control structure for adjusting the temperature, and each temperature control structure comprises a heating mechanism and a cooling mechanism. The operating table further comprises a control system capable of receiving signals of the first temperature sensors so as to control the corresponding temperature control structures to adjust the temperature. Accurate temperature control can be carried out according to different surgical sites, for example, different surgical requirements that neurosurgery needs head low temperature, abdominal surgery needs trunk constant temperature and the like. Compared with a traditional single global temperature control scheme, the local overheating or supercooling risk is effectively avoided, and the intraoperative complications and the postoperative infection rate are remarkably reduced.

The utility model relates to a kind of radiofrequency ablation system based on intraoperative multi-time-course impedance difference prediction catheter radiofrequency ablation intraoperative steam burst and automatic adjustment ablation energy delivery, belong to the intervention therapy technical field of arrhythmia, solve the problem of lacking the function of automatic adjustment ablation energy delivery based on impedance dynamic change in prior art.Rapid decline of impedance in ablation process is an independent risk factor for steam burst.The utility model is set by multiple time windows and corresponding impedance change threshold, to reduce the risk of steam burst in catheter radiofrequency ablation.Both reduce the potential risk of intraoperative complication, and not too frequent cut off ablation process affect the operation process, with good clinical application prospect.

The invention relates to the technical field of medical care informatics, in particular to a risk management method and system for a mammary gland interventional ultrasonic surgery, and the method comprises the steps: judging whether a tissue elasticity initial risk exists or not through an ultrasonic image and an elasticity image which are synchronized in the surgery; judging whether the initial risk of energy deposition exists or not according to the average temperature change rate of the ultrasonic image energy acting area in the operation and the gray scale gradient value of the anatomical boundary; judging whether a physiological compensation initial risk exists or not according to the relevance between the preoperative heart rate variability signal and the mammary gland capillary blood flow signal; determining similar cases in a historical surgical case database by using the initial risk type and the high-risk area calibration result; and determining the real-time risk probability of risk upgrading in the current operation process by using the similar cases, and carrying out risk alarm. According to the technical scheme, the hysteresis problem of traditional single-threshold early warning is solved, accurate risk intervention opportunity judgment is provided for doctors, and the risk of complications in the operation is reduced.

This invention relates to the field of medical device technology, specifically to an adaptive adjustment method for an intraoperative support pillow based on online detection of fatigue characteristics using electromyography (EMG) signals. The method includes: collecting EMG signals from the patient in their initial resting state, using frequency-domain muscle fatigue characteristics in the resting EMG signals as threshold benchmark data; calculating the patient's longest single-position holding time based on their age, weight, gender, and underlying medical parameters; developing a positioning adjustment plan based on the patient's underlying medical conditions, physical condition, and surgical procedure; collecting EMG signals using sensors on the intraoperative support pillow, monitoring cervical spine posture parameters in real time via a posture measurement unit, preprocessing and extracting features from the EMG signals to detect muscle fatigue characteristics; and adaptively adjusting the intraoperative support pillow based on muscle fatigue characteristics, cervical spine posture parameters, the longest single-position holding time, the surgical stage, and the positioning adjustment plan. This invention reduces the risk of intraoperative complications.

The present application relates to the technical field of healthcare informatics, and in particular to a risk management method and system for breast interventional ultrasound surgery, which comprises: determining whether there is an initial risk of tissue elasticity by using intraoperative synchronous ultrasound images and elastography; determining whether there is an initial risk of energy deposition by using the average temperature change rate of the energy action area of the intraoperative ultrasound images and the gray scale gradient value of the anatomical boundary; determining whether there is an initial risk of physiological compensation by using the correlation between the heart rate variability signal before surgery and the breast microvascular blood flow signal; determining similar cases in the historical surgery case database by using the initial risk type and the high-risk area calibration result; and determining the real-time risk probability of risk escalation in the current surgery process by using the similar cases and performing risk warning. Through the technical scheme of the present application, the hysteresis problem of traditional single threshold early warning is solved, precise risk intervention opportunity judgment is provided for doctors, and the risk of intraoperative complications is reduced.
