Embodiment 1
[0031] Such as Figure 1a to Figure 1c as shown,
[0032] A variable-angle V-shaped double-channel working sheath for spinal endoscopic surgery, including a handle main body of the working sheath, wherein a snap ring is arranged on the handle main body of the working sheath, and the snap ring is used to connect the detachable connection handle 1 or The robot or mechanical arm, the detachable connection handle on the clasp, the robot or the mechanical arm, is confirmed by the operation overview before operation, and can also be freely replaced among the three during the operation, all in order to improve the surgical performance. The stability of the overall device, thereby reducing the pressure and fatigue of the doctor's left-handed instrument, the present invention is preferably a detachable connection handle; the snap ring is specifically arranged between the endoscope locking depth regulator 2 and the working sheath channel-3 position, and finally nested and connected wit...
Embodiment 2
[0039] Such as Figure 1a to Figure 3 As shown, the working sheath channel 1 of the working sheath is designed with a water inlet channel 9, a water outlet channel 10 and an endoscope channel 7, and an instrument channel 8 is designed in the working sheath channel 2 4, and the instrument channel 8 is used for installing surgical instruments 13. When removing the soft tissue, the endoscope channel 7 is equipped with an endoscope 11 for accurate and quick resection of the endplate cartilage under direct vision.
[0040]During the operation, if it is necessary to adjust the size of the V-shaped angle between the two channels, you only need to open the elastic stretching structure 6 with one hand, and the V-shaped angle will gradually increase. At this time, when the V-shaped angle in the endoscope 11 When the operation profile reaches the best imaging, the elastic stretching structure 6 can be closed, and with the cooperation of the elastic shaft 5, the V-shaped corner can be loc...
