[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Refer to the instruction manual Figure 1-9 ,like Figure 1 As shown, a device for suction and flushing a neuroendoscopic channel according to an embodiment of the present invention comprises an outer sheath 1 of a neuroendoscopic channel, an inner sheath is inserted into the inner side of the outer sheath 1 of the neuroendoscopic channel, and the inner sheath is an expansion inner sheath 2, as shown in FIG. Figure 3As shown, the inner sheath is a suction flushing inner sheath 3. Through the setting of the suction flushing inner sheath 3, the suction flushing inner sheath 3 is set to be installed with a protective net 5 and not installed with a protective net 5, so as to facilitate flexible selection when using. The inner side of the suction flushing inner sheath 3 is fixedly installed with a suction channel tube 4, as shown in FIG. Figure 9 As shown, a protective net 5 is fixedly installed at the bottom end of the suction channel tube 4.

[0023] It should be noted that, by assembling the neuroendoscopic channel outer sheath 1 with the other three inner sheaths, different effects can be achieved. After the neuroendoscopic channel outer sheath 1 is assembled with the expansion inner sheath 2, its front end is in the shape of a bullet head, which can achieve minimally invasive expansion and separation of brain tissue, and establish a working channel from the brain surface to deep brain lesions. After pulling out the expansion inner sheath 2, the handle at the tail end of the neuroendoscopic channel outer sheath 1 is fixed, so that the endoscope and instruments can be operated in the channel to avoid damaging the surrounding normal brain tissue; when active bleeding occurs in the surgical field and the surgical field is unclear, the suction and flushing inner sheath 3 can be inserted, and the tail end of the suction channel tube 4 is connected to the negative pressure suction tube. The suction and flushing inner sheath 3 can be rotated to achieve continuous suction of infusion bleeding, keeping the surgical field clear, and the surgeon no longer needs to hold the traditional suction device, thereby freeing up the right hand for direct vision. Precise electrocoagulation hemostasis is performed. When flushing is needed, flushing water is connected to the tail end of the suction channel tube 4. The flushing water passes through the suction channel tube 4 directly to the deep surgical field, realizing continuous and stable flushing of the surgical field, thereby avoiding the traditional flushing through the outer opening of the channel and splashing onto the endoscope lens, causing lens blur; when operating in important neurovascular areas, a suction and flushing inner sheath 3 with a protective net 5 is used to achieve small suction and safe suction. When there is no need for suction and flushing, all inner sheaths can be withdrawn to maximize the utilization of the neuroendoscopic channel space. In the process of assembling different inner sheaths, the neuroendoscopic channel outer sheath 1 is fixed to the brain tissue, and there is no need to replace the outer sheath, avoiding multiple puncture injuries, and effectively isolating the instrument operation from invading the normal brain tissue around the outer sheath, thereby improving the convenience of use during surgery, and it is easy to assemble, which is conducive to improving surgical efficiency.
