技术领域technical field
本发明涉及医疗成像领域，尤其涉及一种多焦深、多光谱段的腹腔镜三维监控设备。The invention relates to the field of medical imaging, in particular to a laparoscopic three-dimensional monitoring device with multiple focal depths and multiple spectral segments.
背景技术Background technique
目前，用于医疗领域的体内观察器械通常为一种二维的腹腔镜。这种二维的腹腔镜是一种可通过器管插入体内的单镜头腹腔镜。这种单镜头腹腔镜有穿刺管和设置于其内的光纤穿刺棒，以及安装在光纤穿入端的摄像镜头组成。光纤穿刺棒与相应的显示器连接后，即可通过显示器观察到光纤穿刺棒插入摄像头所摄入的画面。这种单镜头腹腔镜存在的主要问题是所放映的画面无距离感，无法看到立体的深度，从而给手术带来了很大的困难。医生需要借助大量经验去推断病灶部位血管毗邻结构和组织走向的立体关系，这样不仅会延长手术时间，而且容易误伤健康组织，带来严重安全隐患，导致并发症和死亡率几率增加。因此，腹腔镜手术医生需要跨越漫长的学习曲线去尽量规避二维监控带来的缺陷。只有三维显示系统能够还原人眼直视的自然场景，可以获得视野景深，极大地保障手术安全。另外正常组织与病变组织（尤其是肿瘤）在拉曼光谱上存在差异，在手术过程中通过多光谱成像使得病变组织能充分地区分显示出来，能帮助外科医生更容易地发现病灶，做更充分的处理。同时实现术野的三维图像显示与多光谱成像，这对于手术的效率与效果有很显著的提升作用。Currently, the in vivo observation instrument used in the medical field is usually a two-dimensional laparoscope. This two-dimensional laparoscope is a single-lens laparoscope that can be inserted into the body through the organ tube. This single-lens laparoscope is composed of a puncture tube, an optical fiber puncture rod arranged in it, and a camera lens installed at the insertion end of the optical fiber. After the optical fiber puncture rod is connected to the corresponding monitor, the picture taken by the camera when the optical fiber puncture rod is inserted can be observed through the monitor. The main problem of this single-lens laparoscope is that the projected picture has no sense of distance and cannot see the three-dimensional depth, which brings great difficulties to the operation. Doctors need to use a lot of experience to infer the three-dimensional relationship between the adjacent structure of blood vessels at the lesion and the direction of the tissue. This will not only prolong the operation time, but also easily injure healthy tissues by accident, bringing serious safety hazards and increasing the chance of complications and mortality. Therefore, laparoscopic surgeons need to cross a long learning curve to try to avoid the defects caused by two-dimensional monitoring. Only the 3D display system can restore the natural scene directly seen by the human eye, and can obtain the depth of field of view, which greatly guarantees the safety of surgery. In addition, there are differences in the Raman spectra between normal tissues and diseased tissues (especially tumors). During the operation, multi-spectral imaging can fully distinguish and display the diseased tissues, which can help surgeons find lesions more easily and perform more comprehensive procedures. processing. At the same time, the three-dimensional image display and multi-spectral imaging of the surgical field can be realized, which can significantly improve the efficiency and effect of the operation.
