Stereo endoscope assembly and stereo nerve endoscope

Abstract

The invention relates to the technical field of medical instruments, in particular to a stereo endoscope assembly and a stereo neuroendoscopy. The stereo endoscope assembly comprises a lens component,a bendable endoscope body component and an optical cable, the lens component is provided with a specific lens inclination angle, the front end of the lens component faces a target observation point,and the endoscope body component is connected to the rear end of the lens component; and the optical cable is embedded in the endoscope body component, one end of the optical cable is connected to thelens component, and the other end of the optical cable is used for being connected to an image processing assembly. The stereo endoscope assembly can effectively enlarge the visual field range, and can adapt to the operation requirements of irregular shapes of different operation areas so as to acquire the video data with stereo vision, so that the operation is more convenient, finer and more accurate.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a three-dimensional endoscope assembly and a three-dimensional neuroendoscope. Background technique [0002] Surgery for deep brain lesions has a narrow field of view and important structures, which require fine manipulation under microscope magnification. Some lesions are blocked by brain tissue, blood vessels, nerves or bone structures. The current operating microscope has a straight-line field of view and cannot see the lesions in the blocked parts. The operator needs to carefully pull out according to experience. Blindly pulling out may cause blood vessel damage and lead to massive bleeding or nerve damage, resulting in residual tumor or incomplete treatment of lesions. In order to achieve fine operation of the surgical process under direct vision, endoscopes are usually used as important surgical equipment in fine surgery such as the brain. [0003] The endoscop...

Problems solved by technology

[0004] However, the existing neuroendoscopes also have obvious shortcomings, which limit the scope of application in neurosurgery

Due to the difference between the endoscopic wide-angle lens and the angle of the lens, the existing hard mirror lens can be inserted into the nasal cavity through the sphenoid sinus to the saddle area for surgery and into the ventricle for surgery, and can see structures that cannot be seen in the straight-line view of the microscope under the endoscope , but it cannot adapt to the irregular operation area of ​​craniotomy in other parts

However, the existing flexible flexible mirrors can only be used for operations on specific parts such as the midbrain aqueduct.

In addition, both hard mirrors and soft mirrors are single-objective monocular plane vision, without stereoscopic vision, and require repeated training and adaptation by the surgeon.

However, when precise operation is required, the operator has no sense of stereo vision, so there is a risk of accidental injury due to misjudgment of depth. In addition, hard mirrors often require the operator or assistant to hold the mirror body. The operation process is extremely inconvenient and increases the operating effort.
