Description

一种超声治疗头 技术领域
本发明属于超声治疗技术领域， 具体涉及一种超声治疗头。 背景技术
在传统的超声波治疗技术领域中， 由于治疗头在使用的过程中， 其中的超声换能器会产生大量的热， 这些热量如果不及时散去， 就可 能对患者造成灼伤， 并且影响治疗头特别是超声换能器的寿命。
一般情况下， 为了避免治疗头温度过高， 超声换能器通常不得不 在降低功率的条件下使用， 或者先连续使用一段时间， 待其冷却后再 继续使用。 为了解决上面的问题， 通常的做法是在治疗头中配有水循 环冷却装置， 如中国专利 （专利号为： ZL 01144259.X) 中的超声波治 疗仪， 其中的循环水充当冷却液带走换能器产生的热量， 同时也作为 超声耦合剂起到超声耦合作用。 但是水循环冷却装置存在管路容易老 化、 破损， 维护困难、 体积较大等不足， 且循环水的密封问题也是一 个一直困扰整个超声治疗界的难题。 发明内容
本发明所要解决的技术问题是针对现有技术存在的上述不足， 提 供一种无需使用循环液体作为冷却液， 且能够保障超声换能器.所产生 的热量能及时散去的超声治疗头。
解决本发明技术问题所采用的技术方案是该超声治疗头包括外 壳， 外壳内有超声换能器， 外壳的一端开口， 所述开口处由导能窗封 闭， 超声换能器发出的超声波透过导能窗向外发射， 其中， 外壳上开 有进气口和排气口， 所述进气口和排气口之间的腔体形成冷却腔， 超 声换能器工作时产生的热量经由冷却腔后由排气口排出。
在本发明中， 所述冷却腔可以由外壳内进气口和排气口之间的空 腔形成。 所述超声换能器可采用平面式超声换能器或球壳式超声换能器。 导能窗将外壳的开口处密封， 导能窗表面平滑， 由透声材料制成。
外壳底部和超声换能器之间可设置有冷却单元， 所述冷却单元不 使用循环液体， 用于对换能器产生的热量进行散热， 冷却单元可采用 多种形式， 下面是优选的两种形式：
一种是， 所述冷却单元采用轴流风扇， 所述轴流风扇安装于超声 换能器发射面的背面。
排气口.和进气口均设置于所述外壳的侧壁上， 优选排气口位于超 声换能器发射面异侧的附近， 进气口的设置远离排气口。 进一步优选 的是， 所述进气口和排气口分别可采用多个。 在使用轴流风扇时， 进 气口与排气口分别实现冷空气的吸入和热空气的排出， 从而在超声治 疗头内部形成相对独立的进气通道和排气通道。
另一种是， 所述冷却单元可包括依次连接的制冷器和散热器， 所 述制冷器设于超声换能器发射面的背面， 用于对超声换能器降温， 散 热器用于对制冷器进行散热。 优选所述超声换能器和制冷器中间夹有 背衬， 背衬采用导热材料制成， 对于球壳式超声换能器来说， 由于其 形状与制冷器不能完全贴合， 可以将背衬加于超声换能器与制冷器中 间， 背衬上下表面分别适形地贴合于超声换能器与制冷器表面， 有效 地利用制冷器对背衬进行降温； 对于平面式超声换能器， 其无须背衬 也能够直接与制冷器贴合， 但背衬的使用也能够更好地传导制冷器的 冷却作用。 优选超声换能器与背衬之间， 背衬与制冷器之间， 制冷器 与散热器之间 （不使用背衬时， 在超声换能器与制冷器之间， 以及制 冷器与散热器之间） 都涂有导热硅脂。
其中， 所述背衬采用铜材制成， 所述制冷器采用半导体制冷器。 所述散热器采用导热性能强的金属材料制成。
进一步优选的是，在所述散热器的散热方向上还可设有轴流风扇。 当冷却单元中不使用轴流风扇时， 进气口与排气口没有明显的区 分， 热空气可以通过各进气口和 /或排气口与外部空气进行交换。 当冷 却单元中包括有轴流风扇时， 进气口与排气口分别实现冷空气的吸入 和热空气的排出， 在超声治疗头内部形成了相对独立的进气通道和排 气通道。 优选的是， 所述进气口和排气口分别可釆用多个。
此外， 在所述超声换能器和导能窗之间还可填充耦合剂， 以使得 超声换能器发射的超声波能够透过导能窗而进入人体， 所述耦合剂采 用通过真空脱气处理后的超声耦合介质。
本发明超声治疗头没有采用循环液体装置作为冷却单元， 并且能 够保障超声换能器所产生的热量及时散去， 在外壳内留有部分空腔作 为冷却腔以用作散热用的通道， 冷却单元位于外壳底部和超声换能器 之间， 这样可以防止超声换能器工作时产生的热量对患者造成热灼伤， 且能够保障超声换能器在较长的时间内都能正常使用。 附图说明

如图 2所示， 本实施例中， 超声换能器 4采用球壳式超声换能器。 此球壳式换能器与平面式换能器相比， 能够实现发射超声波的自聚焦。
本实施例其余部分的结构与实施例 1相同， 此处不再阐述。 实施例 3 :
如图 3所示， 本实施例中， 超声换能器 4采用球壳式超声换能器； 冷却单元包括依次连接的背衬 9、制冷器 8和散热器 .7以及轴流风扇 6， 背衬 9设于超声换能器 4发射面的背面， 其上下表面分别与制冷器 8 和球壳式超声换能器 4表面贴合， 背衬 9采用导热性强的材料制成， 用于将超声换能器 4工作时产生的热量传导至制冷器 8 ;制冷器 8采用 半导体制冷器， 它紧贴于背衬 9与超声换能器 4接触面的异侧， 实现 对背衬 9的降温； 散热器 7紧贴于制冷器 8与背衬 9接触面的异侧， 用于对制冷器 8进行散热， 从而进一步提高整个冷却单元的冷却效果； 轴流风扇 6位于散热器 7与制冷器 8接触面的异侧， 紧贴外壳 1的底 部； 超声换能器 4与背衬 9之间、 背衬 9与制冷器 8之间、 制冷器 8 与散热器 7之间都涂有导热硅脂。

通过采用本实施例中的冷却单元， 可以对超声换能器 4进行有效 的冷却， 并且避免了冷却过程中流体的使用。
本实施例其余部分的结构与实施例 2相同， 此处不再阐述。 实施例 4:
如图 4所示， 本实施例与实施例 3相比， 除了没有采用轴流风扇 6之外， 其余部分的结构皆与实施例 3相同， 此处不再阐述。
由于本实施例中冷却单元中没有采用轴流风扇，因此进气口 12与 排气口 11的作用没有明显的区分， 热空气既可以通过进气口 12， 也可 以通过排气口 1 1与外部空气进行交换。
