Ultrasonic device for treating prostate disease

Abstract

The invention relates to an ultrasonic wave treating device, which comprises ultrasonic wave detecting treating unit, moving unit and driving unit for driving the detecting treating unit, control unit and image display unit for controlling the detecting treating unit, wherein the detecting treating unit comprises chamber with ultrasonic wave energy converter and ultrasonic wave imager connected to the image display unit; the chamber can be open and closed; when it is open, the ultrasonic wave energy converter expands to two sides of chamber at two sides of ultrasonic wave imager. The invention can avoid image interference between imager and converter, without hurting rectum.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic treatment, relates to an ultrasonic treatment device, in particular to an ultrasonic treatment device suitable for treating prostate diseases. Background technique [0002] Prostatitis is a common disease in adult males, accounting for about 25% to 30% of outpatient urology diseases according to general statistics. In recent years, according to statistics from authoritative departments, about 40% to 60% of young and middle-aged men over 20 years old suffer from chronic prostate Inflammation, about 60% of men over 50 years old, and about 80% of elderly men over 60 years old suffer from prostatic hyperplasia in varying degrees. [0003] At present, there are three main methods for the treatment of prostate diseases, namely drug therapy, surgical treatment and physical therapy. These three treatment methods have their own disadvantages: 1. Drug treatment: because the prostate gland has a dense ca...

AI Technical Summary

Problems solved by technology

These three treatment methods have their own disadvantages: 1. Drug treatment: because the prostate gland has a dense capsule, the drug is not easy to penetrate, so the treatment effect is not ideal; 2. Surgical therapy: BPH can be removed by surgery, but a period There will be hyperplasia after time, and there are certain risks in surgery; 3. Physical therapy: physical therapy is currently a conservative treatment for prostate patients, but most of them are physical therapy methods and cannot be cured.

[0005] U.S. Patents US5676692, US6371903, US5762066, and the focused ultrasonic treatment device disclosed in EP0552995 for treating the prostate generally have the following problems: 1. Due to the limitation of the position of the rectum, the ultrasonic transducer unit has a small focusing angle. For the purpose of treatment, the ultrasonic energy must be increased, which is likely to cause rectal damage; 2. The ultrasonic transducer unit and the ultrasonic graphic device transmit at the same time. Due to the small interval, there will be image interference between the ultrasonic imaging device and the ultrasonic transducer unit; 3. The image transducer is small, and the whole picture of the prostate cannot be confirmed, which is not conducive to timely detection of changes in other tissues such as seminal vesicles after treatment

[0006] Although the ultrasonic therapy device disclosed in Chinese Patent Publication No. CN1342057A can observe the whole picture of the prostate from different angles and can be accurately positioned, its implementation cost is high and the equipment is complicated

In addition, the focus angle of the ultrasonic transducer unit is still small, although corresponding measures have been taken, it is still unavoidable to cause rectal damage in the actual implementation process
