用于医用光学示踪的光纤机构及医用光学示踪系统 技术领域
本发明涉及一种用于医用光学示踪的光纤机构及使用该光纤机构的医用光学示踪系统。
背景技术
临床手术中，由于血管、输尿管、输卵管、气管等腔管通常被组织包裹，外科医生需要经过长期训练，熟悉解剖结构，才能准确分离血管、输尿管、输卵管、气管等腔管。即便是经验丰富的外科医生，有时也会发生误伤血管、或输尿管、或输卵管、或气管等腔管的意外，因此，需要一种能够在组织中准确标识血管、或输尿管、或输卵管、或气管等腔管的装置。
此外，做淋巴结清扫时，通常会紧贴血管进行，因此，也需要对血管的位置和范围进行标定，方便在腔镜下进行外科手术。
综上所述，现有技术尚不能对隐藏在组织中的血管、输尿管、输卵管、输精管、气管等进行可见光标识，不便于在腔镜下手术的识别。因此，需要开发一种在腔镜下可见光标识技术和装置，以便于在腔镜下进行识别血管、输尿管、输卵管、输精管、气管等腔管。
本发明公开了一种基于可见光技术的血管、输尿管、输卵管、输精管、气管等腔管的标识技术，并公开了一种特殊的光纤机构，具有整体示踪功能。
发明内容
本发明的目的在于解决现有临床手术中血管、组织、器官在腔镜下无法准确标识的问题，通过一种能整体示踪的特种光纤的设置，在临床手术中，通过不同颜色光源的设置，该光纤能准确辨别临床手术中需要重点保护的血管、组织或器官，有效避免手术过程中的意外伤害，以便于临床手术的有效实施。

所述光源1发出的光线的颜色可以根据背景颜色或穿透要求进行设置。通过光线的设置，在临床手术中，医生可以直接通过肉眼透过组织看到所述光学示踪载体2所在的位置，进而准确辨别临床手术中，需要重点保护的血管、组织或器官，有效避免手术过程中的意外伤害。所述光源1发出的光线可以根据体腔内的背景颜色或需要穿透的组织进行差异化设置，当需要穿透组织时，红色和黄色为佳，紫色和白色次之，当需要显示血管组织时，光线以绿色为佳。
所述光源1还可以根据需要设置成间断点亮、闪烁等形式。
所述光源1发出的光线的强度也可以根据需要进行调整，以适应不同的临床环境。所述光源1发出的光线的照度可达30万lux，较佳范围在5千lux至15万lux。
所述光源1含控制系统13，所述控制系统13含波长调节机构13-1和光强调节机构13-2，所述波长调节机构13-1能通过波长的调节来调节发出的光线的颜色，所述光强调节机构13-2，能调节发出的光线的照度。
参考图10和图11，所述用于医用光学示踪的光纤机构201含导光接头26，所述导光接头26连接所述光源1与所述导光光纤22。
参考图4和图4-1，本实施例中，所述医用光学示踪系统500还含保护套管5。
所述保护套管5由透明材料制成，所述光学示踪载体2设置在所述保护套管5内。
所述显影机构4可以设置在所述导光光纤22上，也可以单独设置。所述光学示踪载体2、所述显影机构4设置在所述保护套管5内。所述保护套管5的外部可以根据需要设置所述涂层3，如当所述导光光纤22需要进入血管时，所述涂层3可以设计成抗凝涂层，当所述导光光纤22需要进入各种腔体时，所述涂层3可以根据需要设计成亲水涂层或疏水涂层。
本实施例之医用光学示踪系统可以根据需要制造成为可见光示踪医用导管、或可见光示踪实体瘤示踪装置、可见光示踪光纤、或可见光示踪血管示踪装置，在临床手术中，用来示踪血管、食管、输尿管、尿道等腔管，或者示踪和标定实体瘤的位置，如子宫肌瘤、肺肿瘤，肝肿瘤等，提高手术的精准性，避免手术过程中的意外伤害。
介绍的实施例并非实现本发明的唯一结构。虽然本发明的优先实施例已在本文中予以介绍和说明，但本领域内的技术人员都清楚知道这些实施例不过是举例说明而已，本领域内的技术人员可以做出无数的变化、改进和代替，而不会脱离本发明，因此，应按照本发明所附的权利要求书的精神和范围来限定本发明的保护范围。
