The invention relates to an ultrasonic probe position and posture adjustment device for prostatic intervention. The ultrasonic probe position and posture adjustment device comprises an ultrasonic probe position adjustment mechanism, an ultrasonic probe posture adjustment mechanism, an ultrasonic probe feed and autorotation mechanism and an ultrasonic probe. The device adopts a passive operation manner, has eight degrees of freedom and can adjust a position and a posture of the ultrasonic probe and achieve feed and autorotation of the ultrasonic probe; a parallel connection spherical hinge mechanism adopts spherical hinge connection, so that the flexibility of position adjustment is improved; the ultrasonic probe posture adjustment mechanism comprises a distal end parallelogram mechanism and can achieve posture adjustment of the ultrasonic probe around a space fixing point as a sphere center; the surgery safety is improved; the pain of a patient is relieved; with the adoption of brakes, the device can be in a lock state, so that the ultrasonic probe is suspended in any position and posture within a working range and not required to be hand-held by a doctor all the time; the labor intensity is greatly reduced; the surgery precision is improved; the doctor can also perform other operations by both hands; the quantity of medical care personnel assisting in a surgery is reduced.
