WIPO Patent Application WO/2014/162470
Kind Code:
A1
Abstract:
This medical device (10) has a main body (30), an arcuate curved needle (20), a light emitting unit (40), a detection unit (50) and a control unit (60). The light emitting unit (40) is provided in the main body (30) and emits a visible guide light (L1). The detection unit (50) detects the inclination angle θ of the main body (30). The control unit (60) causes the light emitting unit (40) to change the emission angle α of the guide light (L1) depending on the detected inclination angle θ. A user determines as the irradiation target position (F) the intersection point between the body surface (130) and the perpendicular line (V) passing through the puncture target position (P) inside of the body. The user grasps the main body (30) and inserts the curved needle (20), piercing the body. At that time, by moving the main body (30) so as to maintain the state in which the guide light (L1) is irradiating the irradiation target position (F), the needle tip (21) can be simply and quickly guided to the puncture target position (P).
