[0043] 所产生的红外光通过第一光导管 3输入至光纤 14, 并通过光纤 14照射于人体部 位, 控制部 22控制成像部 20中的红外摄像头拍摄光纤 14所照射的人体部位的第 一影像。 进一步地, 所产生的红外光通过第二光导管 4输入至旋转部 10, 并通过 旋转部 10照射于人体部位, 控制部 22控制成像部 20中的红外摄像头拍摄人体部 位的第二影像。 医生可以在显示装置上实吋观察第一影像及第二影像, 并及吋 调整刺入人体部位的位置。 具体地说, 若第二影像中显示没有病变组织, 而第 一影像中显示有病变组织, 则将所述刺入部 15调整到光纤 14所在的位置, 以获 得光纤 14所在位置的病变组织。
[0044] 当第一影像及第二影像中均显示有病变组织, 则通过旋转手柄 13转动所述旋转 部 10, 使得所述旋转部 10的底部摘取病变组织, 之后将所述活检穿刺针 1拔出并 将摘取的病变组织送交医院的检验部做进一步检测。
[0045] 以上仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是利用本 发明说明书及附图内容所作的等效结构或等效功能变换, 或直接或间接运用在 其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
工业实用性
相较于现有技术, 本发明所述具有双光路影像扫描功能的活检穿刺针控制系统 采用了上述技术方案, 达到了如下技术效果: 本发明可以实吋获取人体部位的 影像, 同吋通过第一光路及第二光路的照射人体部位, 可以扩大人体部位成像 的范围, 方便医生通过活检穿刺针获取病变组织, 降低了医疗风险, 方便了医 务人员及患者。
