At this time, the neuroendoscope 1 is fixed on the first In the circular structure formed by the half ring 48 and the second half ring 49, the third knob 46 is then rotated, and the fourth screw 45 rotates in the fourth screw hole 44, so that the lower end of the fourth screw 45 is separated from the second At this time, the shaft 42 can be rotated on the second shaft 42 to form the circular structure formed by the first semicircular arc and the second semicircular ring 49, so that the lower end of the neuroendoscope 1 is tilted directly below the microscope 3. Until the lower end of the neuroendoscope 1 is directly below the objective lens 5 of the microscope 3, stop rotating the circular structure formed by the first semicircular ring 48 and the second semicircular ring 49, and turn the third knob 46 to make the The lower end of the four screw 45 is pressed against the second shaft 42 so that the sleeve 43 cannot continue to rotate on the second shaft 42. At this time, the neuroendoscope 1 is fixed at a suitable angle to make the lower end of the neuroendoscope 1 Located within the field of view of the objective lens 5 of the microscope 3; during the operation, connect a camera to the video interface 7 of the neuroendoscope 1, and the camera transmits the image to the monitor for display. The surgeon can observe the neuroendoscope 1 through the camera With the image captured by the lens, the assistant surgeon can see the lower end of the neuroendoscope 1 (that is, behind the operation area) through the eyepiece of the microscope 3. This reduces the possibility that the neuroendoscope 1 cannot see the back of the operation area during use. Risk of harm to the patient. By providing an extension rod 53 at the left end of the bolt 52 and a fourth knob 54 at the rear end of the extension rod 53, it is convenient to turn the bolt 52 by turning the fourth knob 54.

The above are only the embodiments of the present invention, and do not limit the scope of the present invention. Any equivalent structure made by using the content of the description and drawings of the present invention, directly or indirectly applied to other related technical fields, is the same in the present invention. Within the scope of patent protection.
