Abstract

The present invention relates to an ultrasound treatment clamp. The ultrasound treatment clamp comprises ultrasound therapy applicators and handles connected to the ultrasound therapy applicators. The handles are clamp-shaped. The two ultrasound therapy applicators with their central axes overlapping each other are mounted face to face on the two clamps of the clamp-shaped handles respectively. A parallel moving mechanism for keeping the two ultrasound therapy applicators in parallel when moving along with clamps is connected between the two clamps. The present invention has a compact structure, a convenient operation, a low treatment cost, a capability of quickly causing a coagulative necrosis of the diseased part. Furthermore, the present invention has an abroad use in treating many kinds of diseases.
