Abstract

人的体表或腔体表面的病变部位产生热效果的光辐
射治疗仪,其特点是光源为温度可达1900—2100K
的热光源,并有能对传导的大部分光产生全反射的光
导体。本仪器结构简单,对光线利用率高,对宫颈糜
烂的治疗有很好的效果。
Description
本发明涉及一种光幅射治疗仪,特别是一种利用光线在人的腔体内表面或体表病变部位产生热效果的光幅射治疗仪。
对于某些人体腔体部位的疾病,例如宫颈糜烂可用激光照射的方法治疗。对于激光治疗仪,例如中国鹭岛公司出产的LD-10B二氧化碳激光治疗仪,仪器的操作复杂,而且激光对病变部位的烧灼温度较高,容易使患者感到不适和疼痛。激光治疗仪的另一个不足之处是光束很细,在使用中有的病变部位会照射不到,对较大面积的病变部位的医治不彻底。
还有一些光幅射治疗仪,它们的光导装置有种种缺陷,使光幅射在集中和传导过程中能量损失较大,这样就需要加大光源的功率,同时要在光导部件外部加装散热装置,以免烫伤与光导部件周围接触的人体组织。
本发明的目的之一是在光幅射治疗仪中提供其它幅射源取代激光,对病变部位产生热效果,并使光源部件的结构简单。
本发明的另一目的是提供比激光光束(直径≤2mm)粗的光束,使病变的所有部位都被照射到。
本发明的又一目的是提供在一定波长的幅射光束,使它们在幅射到病变部位及正常部位时达到的温度与激光达到的温度相比较低。
本发明的又一目的之一是提供一种光导体,使治疗的光在光导体中的传导损失很小。
本发明的目的还在于提供一些根据光学原理制成的反光,聚光装置,最大限度的利用光源所产生的光幅射的能量。
本发明涉及一种光幅射治疗仪,特别是一种利用光幅射在人的腔体内表面和体表病变部位产生热效果的光幅射治疗仪,包括壳体,装于壳体内的光源和反光镜,反光镜位于光源后方,特点是光源为温度可达1900-2100K的热幅射源,光源前方装有伸出壳体以外的能对传导的大部分光幅射产生全反射的光导体。
温度可达1900-2100K的光源,例如卤钨灯,发出的光的波长大部分在0.4~5m之间,能使受照射的病变细胞的蛋白质固化,造成病变细胞坏死。
光导体,例如红外透射石英玻璃棒,光导管,光纤缆等,因外部是光疏媒质或折射率小的材料,可使光源的前方散射和反射镜反射到前方的大部分光在光导体内部全反射传导,最后光源的大部分光幅射可集中照射到病变部位,光导体越靠近光源,接受的光幅射越多。
在光导体是红外透射石英玻璃棒的情况,棒本身的材料对传导的红外线吸收很少,能更有效地利用光源的光。
在光导体与光源间可加装两个凸面相对的球面或非球面平凸柱形透镜,这样可将散射和反射到它上面的光集中成较均匀的近似平行光,使到达光导体入射端的光幅射更均匀集中,进一步减少光幅射的传导损失。这种附加透镜对光导和是光纤缆,光导管或红外透射石英玻璃棒的情况都适合。
光导体外部可有保护套,光导体与保护套之间用支承固定,使保护套与光导体之间的空隙,空隙间可填充合适的光疏媒质,优选是空气。
光导体可并排附加一个成像光导纤维,这样可以在治疗过程中观察照射的部位和治疗的情况。对于光导体是光纤缆的情况,可在光纤缆中放置至少一根成像光导纤维。为更清楚,更大范围地观察,成像光导纤维端部可装接窥镜。
反光镜的表面可以用金属镀膜。各种金属对不同频率的光的反射能力不同。对于本发明所用的光源,即绝大多数发射的光在0.4~5m波长内的光,优选铜作镀膜。
在壳体上可装设冷却孔道,对壳体和反光镜冷却。
本发明的光幅射治疗仪与现有技术相比,具有以下优点:
1、采用了装置简单,对病变部位治疗的温度较低,照射面积大,疗效好的光幅射源。
2、采用了传导中光损失很小的光导体及附加装置,使光的利用率高,热损失小。
本发明的光幅射治疗器经临床使用,对不同年龄,不同病变程度的宫颈糜烂患者都有满意的效果。对500例临床治疗的统计表明有效率接近100%,一次治愈率达98%。三个月后对病人随访,病人的病变处没有复发,病变部位的弹性恢复正常,宫颈表面恢复平滑并且没有明显的疤痕。
