Description

Multi-mode lighting device for brain nerve operation endoscope Technical Field The invention relates to a human living article, in particular to a medical instrument, and particularly relates to a multi-mode lighting device for a brain neurosurgery endoscope. Background The endoscopic saddle area lesion excision is a conventional and complicated skull base operation of neurosurgery, tumors often affect the cavernous sinus and internal carotid artery, and safe excision of the tumors while protecting brain important blood vessels is a key point of the operation. An endoscope is an electronic instrument commonly used for medical examination and industrial flaw detection, and comprises an insertion part and an operating handle, wherein the insertion part extends into a human body or equipment, the operating handle controls the movement of the insertion part, the shooting operation, the lighting operation and the like, the insertion part comprises an insertion tube and a tip, and a camera and a light source are arranged on the tip. Lesions that cannot be visualized by X-rays can be seen with an endoscope. In the prior art, the illumination of a cranial nerve endoscope used in neurosurgery relies on white light front-emitting illumination. However, this illumination has a significant disadvantage in that it lacks sufficient illumination of the surrounding area of brain tissue, resulting in difficulty in achieving a multi-faceted spot illumination of brain tissue by the physician during the procedure. Meanwhile, the prior art also fails to fully utilize the wavelength characteristics of light to provide a developed image of blood vessels in brain tissue, thereby increasing the risk of surgery. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the multi-mode lighting device for the brain nerve operation endoscope, which overcomes the defects of the prior art, has reasonable design, realizes perspective lighting on brain tissues by a front lighting mode and a side back lighting mode, improves the lighting intensity, further enhances the observation effect on blood vessels in the brain tissues, and improves the safety and the effectiveness of the operation. In order to achieve the above purpose, the invention is realized by the following technical scheme: the multimode illumination device for the cranial nerve operation endoscope comprises an end socket, wherein an instrument channel port and a camera component mounting channel are arranged in the middle of the end socket, a camera component is mounted in the camera component mounting channel, an illumination mounting channel is formed in the end socket, and a front-emitting illumination optical fiber bundle is mounted in the illumination mounting channel; The rear end of the end socket is fixedly provided with a cylindrical socket, the rear end of the cylindrical socket is connected with an endoscope channel tube, a plurality of optical fiber holes are uniformly formed in the circumferential surface of the cylindrical socket, radial illumination optical fiber bundles are fixedly arranged in the optical fiber holes, and the rear ends of the front-emission illumination optical fiber bundles and the radial illumination optical fiber bundles penetrate through the endoscope channel tube and correspond to a luminous source in an endoscope. Preferably, the illumination installation channel is provided with two, and equal fixed mounting has preceding penetrating illumination fiber bundle in two illumination installation channels, apparatus access, camera subassembly installation channel and two illumination installation channels encircle and the interval sets up around the axis of end seat, and two illumination installation channels symmetry set up in the both sides of camera subassembly installation channel. Preferably, the rear section of the end socket is in a truncated cone structure with wide front and narrow rear. Preferably, the optical fiber holes are arranged in a cross arrangement on the circumferential surface of the cylindrical tube seat. The present invention provides a multi-modal lighting device for a brain neurosurgical endoscope. The endoscope has the advantages that the luminous source inside the endoscope is controlled to be started, so that the front-emitting illumination optical fiber bundles in the front-end illumination installation channel of the end socket illuminate, and meanwhile, each radial illumination optical fiber bundle in the optical fiber hole on the side surface of the cylindrical socket illuminates the periphery of brain tissue in multiple points, so that a more comprehensive brain tissue illumination effect is provided for an operation through interaction between the front-emitting illumination optical fiber bundles and the radial illumination optical fiber bundles, and observation of blood vessels in the brain tissue is enhanced, so that operation risks are reduced.
