specific Embodiment approach 1
[0010] Specific implementation mode one : combined figure 2 and image 3 This embodiment will be described. The medical endoscope including a structured light three-dimensional imaging system of this embodiment includes a working mirror tube, and the working mirror tube includes an imaging channel 1 and an illumination channel 2, and the illumination channel 2 has a built-in illumination fiber 3 , it also includes a calculation processing module 4, the signal input terminal of the calculation processing module 4 is connected to the electrical signal output terminal of the imaging channel 1;
[0011] It also includes a structured light channel 5. The structured light channel 5 is placed in the illumination channel 2. The light beam output from the end of the illumination fiber 3 is received by the structured light channel 5. The light beam passes through the structured light channel 5 to generate structured light. The structured light is output from the structured light cha...

The invention provides a medical endoscope containing a structured light three-dimensional imaging system, which relates to a medical endoscope, solves the problem that the conventional three-dimensional observing technology can not be directly applied to the medical endoscope due to space limit in the brain surgery of nasal cavity expansion. The medical endoscope comprises a working scope tube, a computing and processing module and a structured light channel, wherein the working scope tube comprises an imaging channel and an illuminating channel; illuminating optical fibers are arranged in the illuminating channel; the signal input end of the computing and processing module is connected with the electric signal output end of the imaging channel; the structured light channel is arranged in the illuminating channel; the light beam outputted from the tail end of the illuminating optical fiber is received by the structured light channel; the light beam generates structured light after passing through the structured light channel; and the structured light is outputted out of the illuminating channel through the structured light channel. The invention overcomes the defects of the prior art and can be applied to the brain surgery of nasal cavity expansion.
Description
technical field [0001] The invention relates to a medical endoscope. Background technique [0002] Endoscopic imaging technology is a typical medical imaging technology, which plays an important role in medical diagnosis and surgical navigation. As people pay more and more attention to the accuracy of diagnosis and surgical navigation, the application of 3D imaging technology in medical endoscopes is also increasing. Taking brain tumor surgery as an example, in traditional brain tumor treatment methods, such as craniotomy, the surgical method of cutting the patient's skull or facial bones is often used, which often seriously damages the patient's appearance and requires a long postoperative recovery period . Recently, expanded endonasal neurosurgery (EEN, Expanded Endonasal Neurosurgery) has received great attention in the clinical treatment of brain tumors. This surgical protocol uses tiny endoscopes and surgical equipment inserted into the nose to find the precise locat...
