Problems solved by technology

There are some shortcomings in the existing products that use HIFU technology to treat tumors: 1. The existing products have a large focal area (the ratio between the long and short axis is large), and the maximum ultrasonic sound intensity in the focal area is lower than 15000W / cm 2 , so the treatment effect is poor and the treatment time is long
2. Using B-ultrasound two-dimensional diagnosis and two-dimensional treatment methods, the nature and structure of the lesion cannot be completely judged and treated
3. None of the existing products has the function of real-time monitoring of the body surface of the treated area, which is prone to burns and deviation of the treatment site due to changes in the patient's position
4. None of the existing products can quickly, intuitively and qualitatively judge the therapeutic effect

Embodiment Construction

[0019] Such as figure 1 Shown: an ultrasonic focusing knife for tumor treatment is composed of a combined treatment head, an ultrasonic power source, a medium water treatment device, a B-ultrasound machine, a treatment bed, a main controller and an industrial computer. The industrial computer is the control center of the ultrasonic focusing knife for tumor treatment. It adopts a Pentium 3 or higher processor, and its I / O configuration is DMC300 motion control card, PC-6407 switch value output card, PC-6405 switch value input card, PC-6320 A / D card and MVPCI image acquisition card. The B-ultrasound machine adopts the CX-900C type, and the medium water treatment device adopts the CZ901-6 type.

[0020] The combination treatment head 12 is installed on the arc arm 9 of the five-dimensional motion mechanism; there is a water tank for storing medium water in the middle of the treatment bed, the medium water treatment device is connected with the water tank, and the arc arm is pla...

Abstract

A focusing ultrasonic knife for treating tumor is composed of a combined treating head installed to a 5-D arc arm in the water tank on therapeutic bed, ultrasonic power source, medium water treater, ultrasonography B machine, therapeutic bed, main controller and industrial control computer. Its avdantages are precise focus, high power, more wave-field modes, and real-time monitor.

Description

1. Technical field [0001] The invention relates to an ultrasonic focusing knife for tumor treatment which utilizes ultrasound to scan and treat tumors. 2. Background technology [0002] Modern medical research has found that tumor cells are less resistant to heat than normal cells. When the temperature is between 42.5 and 45 degrees, tumor cells die within 30 minutes. It takes about 3 seconds to kill tumor cells at 60 degrees Celsius, but it only takes 0.1 seconds to kill tumor cells at 100 degrees Celsius. tumor cells. Taking advantage of this feature, using High Intensity Ficused Ultrasoelnd-HIFU technology to treat tumors has become a development trend at home and abroad. The ultrasonic beam is focused in the human body, so that the high-intensity ultrasonic energy at the focal point acts on the target tissue (tumor) in the human body, and is irradiated by high-intensity ultrasonic (up to tens of thousands of watts per square centimeter) for a short time (0.5s~5s) , pro...
