Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The invention consists of an X-axis moving mechanism, a Y-axis moving mechanism, a slide table and three telescopic rods. Among them, the definition of X-axis and Y-axis follows the general practice of tumor radiation therapy, X-axis is defined as from head to foot, and Y-axis is defined as from left hand to right hand; in the implementation of the mechanism, they are regarded as equivalent. Such as figure 2 As shown, the X-axis moving mechanism is composed of a motor, a screw, a screw nut and a guide rail. The first motor 7 is connected with the first screw rod 9 and is fixed under the treatment bed 6, and the first screw nut 8 is connected with the bracket 3, so that the first motor 7 can drive the treatment bed 6 to move along the guide rail 5 in the X-axis direction . The composition of the Y-axis moving mechanism is the same as that of the X-axis moving...

Abstract

The serially and parallel connected scanner for high strength supersonic focus therapeutic system consists of an X axis shift mechanism, a Y axis shift mechannism, a sliding platform, and three telescopic rods. The X axis shift mechanism drives the therapeutic bed, the Y axis shift mechanism drives the sliding platform, and each of the telescopic rods, the top ends of which constitute a triangle, has an end fixed into the sliding platform and the other end connected tothe supersonic combined probe. The present invention has two serial linear shift coordinates and three parallel coordinates, has simple structure, high precision, low cost and large moving space, and is easy to be used in 3D motion via multiple-shaft linkage.

Description

technical field [0001] The invention relates to a scanning device, in particular to a series-parallel scanning device used in a high-intensity ultrasonic focus therapy system. Background technique [0002] Cancer is a great enemy of human beings, and cancer patients account for about 10%-20% of the annual death population. Existing cancer treatment methods are diverse, such as surgical resection, radiation therapy, chemotherapy, biological therapy, laser therapy, cryotherapy, etc., all of which have certain curative effects, but have limitations in terms of curative effect, side effects, and economic efficiency. Human beings are always looking for new cancer treatment methods, and high-intensity focused ultrasound (HIFU) non-invasive surgical technology is one of them, and it has now become one of the important cancer treatment methods. HIFU is a kind of mechanical vibration energy, which belongs to non-ion radiation, and it is not accompanied by radiation damage and pollut...
