During the working process, the feeding wheel stepper motor can drive the feeding driving wheel to complete the process of the elastic vent pipe being transported to the airway inside the human oral cavity.
[0052] Working process:
[0053] Movement of the tongue depressor body: The patient wears an open mouth device to ensure that the patient's mouth is in an open state, and the mouth opening space is larger than the device size. The binocular camera is used to detect the mouth opening position. Since the binocular camera is connected to the controller, the controller can obtain the feedback information of the internal oral environment of the binocular camera, and then control the six-degree-of-freedom mechanical arm to extend the tongue depressor body into the human oral cavity; the binocular camera detects the internal oral environment and feeds back to the controller, and the controller controls the servo motor to rotate so that the end of the tongue depressor body is extended into the mark point in the human body. The connecting rod sub-mechanism always moves in coordination with the position of the tongue depressor during the movement of the tongue depressor to ensure that the trachea can always fit the tongue depressor. In the present invention, the mark point in the human body is the throat or other pre-set position, and technical personnel in this field can set it according to actual conditions.
[0054] Intubation: Figure 8 As shown, after reaching the mark point, the fully automatic double-flexible arm tongue depressor mechanism stops moving, and the controller controls the tube inlet stepper motor 51 to rotate, so that the elastic ventilation tube 6 moves toward the tongue depressor body 34, and the lower end of the elastic ventilation tube 6 can be cooperated and set in the semi-enclosed tool guide groove 3421 of the tongue depressor body 34; during the driving process of the tube inlet stepper motor 51, the controller also needs to adjust the connecting rod driving stepper motor to make the transmission connecting rod move and ensure that the elastic ventilation tube 6 can always be attached to the semi-enclosed tool guide groove 3421 of the tongue depressor body 34 during this process.
[0055] Evacuation: If Fig. 9 As shown, after the binocular camera determines that the elastic ventilation tube has reached the designated intubation position, the electromagnetic switch 55 loses power, the mounting buckle 54 is released, the elastic ventilation tube 6 is separated from the tube entry mechanism, and then the six-degree-of-freedom mechanical arm and the fully automatic binocular flexible arm tongue depressor cooperate to return to the original path and exit the human oral cavity to complete the intubation process. The designated intubation position is generally the airway, or other predetermined positions, and those skilled in the art can set it according to actual conditions.
[0056] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
