Abstract: A vascular puncture device punctures a blood vessel using an imaging unit that comes into contact with a skin surface and acquires a cross-sectional image of a human body, an inner needle including a sharp needle tip, a flexible outer tube covering the inner needle, a drive unit moving the inner needle and the outer tube, and a detection unit detecting puncture of the needle tip with respect to a blood vessel back wall, and includes a control unit capable of receiving information on the cross-sectional image, controlling an operation of the drive unit, and receiving a detection result from the detection unit. The control unit controls the drive unit to move the inner needle and the outer tube to puncture the blood vessel with the inner needle, and controls the drive unit to stop the puncture with the inner needle.

Abstract: An assistance system includes a schedule information acquisition unit that acquires disease information on the surgery and blood vessel information relating to a shape of a portion capable of applying a backup force to the catheter by coming into contact with the catheter in a blood vessel of the patient, a past information acquisition unit that acquires a shape of a catheter used for a past similar surgery having the disease information coinciding with that of the surgery and having the blood vessel information similar to that of the surgery, and a proposal unit that corrects the shape of the catheter used for the past similar surgery, based on a comparison result obtained by comparing the blood vessel information on the surgery with the blood vessel information on the past similar surgery, and that proposes a catheter having the corrected shape, as the catheter to be used for the surgery.

Abstract: An assistance system capable of efficiently selecting a proper doctor from a plurality of doctors in accordance with physical conditions of the doctors and surgery difficulties on a scheduled surgery date. An assistance system includes an information acquisition unit that acquires disease information, lesion area information, and a scheduled surgery date of a scheduled surgery, a lesion area evaluation unit that uses surgery information on a past similar surgery having the lesion area information similar to that of the scheduled surgery, a doctor evaluation unit that uses surgery information on the same past disease surgery performed by each of the plurality of doctors and having at least disease information coinciding with that of the scheduled surgery, and a proposal unit that proposes the doctor whose doctor score falls within a range based on the lesion area score, as a surgeon-in-charge for the scheduled surgery.
