The application relates to a control method and system of an arterial compression device, and solves the problem that neither unified parameter setting of a mechanical fixed mode nor simple feedback logic of a primary electronic regulation mode establishes deep connection with blood vessel characteristics and individual conditions, leading to mismatching of compression parameters and actual hemostasis requirements, the method comprising the following steps: real-time acquisition of current pressure of a compression unit and cumulative duration during timing, when the cumulative duration reaches a time interval of a preset curve, a decompression operation is performed according to a corresponding decompression value of a personalized decompression curve; if the current pressure deviates from a theoretical value of the curve by more than a preset deviation value, the decompression amplitude is simultaneously corrected according to the deviation value, and the correction amount is positively correlated with a blood vessel elasticity parameter; when the cumulative duration reaches a total compression time set by the curve, the termination pressure set by the curve is regulated and maintained for a preset duration. The application has the following effects: individualized precise compression is realized, and hemostasis safety and patient comfort are improved.

The utility model discloses a diabetic foot decompression device which comprises a bottom plate, a fixing frame is installed at one end of the top of the bottom plate, and when a movable block moves outside a threaded rod, cylindrical blocks at the two ends of the outside can be synchronously driven to slide inside a sliding groove; when the two cylindrical blocks slide, the two cylindrical blocks drive the adjusting plate to rotate through the supporting rods connected with the outer parts of the cylindrical blocks to adjust the angle, so that the diabetic patient can be massaged and decompressed when lying or sitting. On the basis that the foot angle of the pressure reduction operation can be adjusted, a specific massage pressure reduction mode is carried out according to the characteristics of the arch and toe areas, and meanwhile the temperature of the sole in the process can be detected.

The utility model discloses a variable bone hook and depth limiting type spinal minimally invasive decompression operation robot belongs to medical instrument technical field.
