[0015] As Figure 1 shown, the natural orifice surgery robot trolley with the laser positioning and ranging device provided by the embodiments of the present application comprises a trolley base 10, a mechanical arm 11 installed on the trolley base 10, and a laser positioning and ranging device 12. The trolley base 10 further comprises a trolley base body 101 in the shape of a cuboid and hollow inside, and a roller 102 installed at the bottom of the trolley base body 101. The laser positioning and ranging device 12 is installed at the middle position of the outer vertical surface of the trolley base body 101.

[0016] As Figure 2 shown, the laser positioning and ranging device 12 comprises an installation base plate 1, an adjusting screw 2, a lock nut 3, a laser generator 4, and an adjusting rod screw 5. The laser generator 4 comprises two laser emission holes: a first laser emission hole 41 and a second laser emission hole 42.

[0017] The adjusting screw 2 and the lock nut 3 are installed on the installation base plate 1 through threaded connection. The head, tail and cylindrical head side of the adjusting screw 2 are all provided with threaded holes; the threaded holes of the head and tail are used for installing a jacking screw which passes through the laser generator 4 of the adjusting screw 2. The thicker optical axis part of the adjusting screw 2 is provided with a through hole through which the laser generator 4 passes. The adjusting rod screw 5 is installed in the threaded hole of the cylindrical head side. The lock nut 3 prevents the adjusting screw from loosening.

[0018] The laser generator 4 can emit laser light rays after being powered on. The laser light rays emitted by the laser generator used are respectively a cross line (A in Figure 6 ) and a horizontal line (B in Figure 6 ).

[0019] The adjusting rod screw 5 passes through the installation base plate 1 and is connected in the threaded hole of the cylindrical head of the adjusting screw 2 through threaded connection, so as to finely adjust the angle of the adjusting screw 2.

[0020] The adjusting screw 2 passes through the mounting base plate 1 and is locked by a lock nut 3; the laser generator 4 passes through the through hole of the light axis part of the adjusting screw 2, then the jacking screw is screwed into the threaded holes in the head and tail of the adjusting screw 2 to jacks up the laser generator 4; the jacking screw is finely adjusted, and the center points of the two laser beams are adjusted on the same vertical line and perpendicular to the horizontal line of the cross laser; the adjusting rod screw 5 is screwed on the threaded hole on the side of the cylindrical head of the adjusting screw 2 and can be pushed up and down to finely adjust the angle of the adjusting screw 2.

[0021] As shown in Figure 8 The laser positioning and ranging device 12 is assembled and installed on the installation position of the natural orifice transluminal surgery robot trolley with the laser positioning and ranging device.

[0022] After emitting the laser, the slave mechanical arm trolley is aligned with a vertical plane (wall), the upper cross laser emitting hole is first finely adjusted, the adjusting rod screw 5 is pushed, the horizontal line of the cross laser is overlapped with the required patient height value Y on the vertical plane, and the patient height value Y is ensured to meet the requirement; then the slave mechanical arm trolley is pushed, the front end surface of the slave mechanical arm trolley is pushed to the required distance X between the patient and the slave mechanical arm trolley; then the trolley is pushed, and the lower laser emitting hole is finely adjusted, the adjusting rod screw 5 is pushed, the horizontal line of the cross laser is overlapped with the horizontal line of the cross laser, and the center points of the two laser beams are adjusted on the same vertical line when the laser positioning and ranging device is assembled, so that the two center points are overlapped, the horizontal lines are overlapped, and the laser positioning and ranging device is calibrated.

[0023] When the slave mechanical arm trolley is too far or too close to the patient, the intersection of the two laser beams is obviously not overlapped, the intersection of the two laser beams and the horizontal line are overlapped by pushing the slave mechanical arm trolley, and whether the distance X between the patient and the slave mechanical arm trolley and the patient height value Y are suitable can be judged.
