Description

***疾病的超声波治疗装置 技术领域  Ultrasonic treatment device for prostate diseases
本发明属于超声波治疗技术领域， 涉及一种超声波治疗装置， 特别涉及一种适用于治疗***疾病的超声波治疗装置。 背景技术  The invention belongs to the technical field of ultrasonic treatment, and relates to an ultrasonic treatment device, in particular to an ultrasonic treatment device suitable for treating prostate diseases. Background technique
***炎是成年男性的常见病， 一般统计约占泌尿科门诊疾病 的 25%〜30%， 近年来， 据权威部门统计， 20岁以上的青、 中年男性 约 40%— 60%患有慢性***炎， 50岁以上的男性约 60°/。， 60岁以上 的老年男性约 80%以上不同程度患有***增生。  Prostatitis is a common disease in adult males. The general statistics account for about 25% to 30% of urological outpatient diseases. In recent years, according to the statistics of authoritative departments, about 40% to 60% of young and middle-aged men over 20 years old suffer from chronic diseases. Prostatitis, about 60°/m for men over 50 years old. More than 80% of older men over the age of 60 have prostate hyperplasia to varying degrees.
目前治疗***疾病主要有三种方法， 即药物治疗、 手术治疗 和物理治疗。 此三种治疗方法各有其缺点： 1、 药物治疗： 由于前列 腺体有一层致密包膜，药物不易透入进去，因此治疗效果不理想； 2、 手术疗法： ***增生可通过手术切除， 但一段时间后还会增生， 且 做手术有一定的风险； 3、 物理疗法： 物理疗法是目前对***患者 所采取的保守疗法， 但多为理疗手段， 不能根治。 因此这几种方法都 不是行之有效的治疗方法， 不能减轻***患者的痛苦。  There are currently three main methods for treating prostate diseases, namely, medical treatment, surgical treatment, and physical therapy. These three treatment methods have their own shortcomings: 1. Drug treatment: Because the prostate body has a dense capsule, the drug is not easy to penetrate, so the treatment effect is not satisfactory; 2. Surgical treatment: Prostatic hyperplasia can be surgically removed, but a section After time, there will be hyperplasia, and there are certain risks in surgery. 3. Physical therapy: Physical therapy is a conservative treatment for prostate patients, but it is mostly a physiotherapy method and cannot be cured. Therefore, these methods are not effective treatments and can not alleviate the pain of prostate patients.
近几年， 高强度聚焦超声广泛地用于肿瘤治疗， 且成为目前国 际上最先进的无创伤治疗手段，同时也使利用超声波技术治疗*** 疾病成为可能。这种治疗装置通过放置在患者直肠腔内的超声聚能探 头， 将超声波聚焦于***病灶， 利用超声波的穿透性、 方向性、 聚 焦性好等特点， 使病灶瞬间产生不可逆热凝固性坏死， 坏死组织被吸 收、 溶解并排出体外， 从而达到治疗的效果。  In recent years, high-intensity focused ultrasound has been widely used in cancer therapy, and it has become the most advanced non-invasive treatment in the world, and it has also made it possible to use ultrasound technology to treat prostate diseases. The therapeutic device focuses the ultrasound on the prostate lesion through an ultrasonic concentrating probe placed in the rectal cavity of the patient, and utilizes the characteristics of ultrasonic penetration, directionality, and good focusing to cause irreversible thermal coagulative necrosis instantaneously. The necrotic tissue is absorbed, dissolved and excreted to achieve a therapeutic effect.
美国专利 US5676692、 US6371903、 US5762066 , 以及 EP0552995 中公开了用来治疗***病的聚焦超声治疗装置，所公开的这些装置 普遍存在以下问题： 1、 由于直肠位置的限制， 压电换能器单元聚焦 夹角小， 若为达到治疗目的， 必需提高超声能量， 这样容易引起直肠 损伤； 2、 压电换能器单元与超声图形装置同时发射， 由于所在区间 较小， 超声图像装置与压电换能器单元之间会产生图像干扰； 3、 图 像换能器较小， ***全貌不能确认， 不利于及时发现治疗后其它组 织 （如精囊组织） 的变化。 Focused ultrasound treatment devices for treating prostate diseases are disclosed in U.S. Patent Nos. 5,676,692, US Pat. No. 6,371, 903, U.S. Patent No. 5,762, 066, issued to U.S. Patent No. 5, 055, 995, the disclosure of which are incorporated herein by reference to the entire disclosure of the present disclosure. The angle is small. If it is for therapeutic purposes, it is necessary to increase the ultrasonic energy, which is easy to cause rectal injury. 2. The piezoelectric transducer unit and the ultrasonic graphic device emit at the same time. Due to the small interval, the ultrasonic image device and the piezoelectric transducer Image interference occurs between units; Like a small transducer, the entire prostate can not be confirmed, which is not conducive to timely detection of changes in other tissues (such as seminal vesicles) after treatment.
中国专利公开号 CM342057A中所公开的超声波治疗装置虽然能 从不同角度观察***全貌， 而且可以精确定位， 但其实施成本高， 设备复杂。 发明内容  Although the ultrasonic treatment device disclosed in Chinese Patent Publication No. CM342057A can observe the entire appearance of the prostate from different angles and can be accurately positioned, the implementation cost is high and the equipment is complicated. Summary of the invention
