[0030] An anesthesia pharyngoscope comprises a hand-held mechanism 1, a rotating mechanism 2 and a laryngoscope 3, wherein the hand-held mechanism 1 is rotatably connected to the laryngoscope 3 via the rotating mechanism 2. The hand-held mechanism 1 comprises a hand-held handle 11 and a connecting block 12 fixedly connected to the hand-held handle 11. The rotating mechanism 2 comprises a fixed seat 21 arranged on the connecting block 12, a connecting sleeve 22 rotatably connected to the fixed seat 21, a fixed face gear 23 arranged at one end inside the connecting sleeve 22, a movable face gear 24 matched with the fixed face gear 23, a spring 25 installed between the fixed seat 21 and the movable face gear 24, and an adjusting rod 26 fixedly connected to the end surface of the movable face gear 24 and rotatably connected to the fixed face gear 23 and the connecting sleeve 22. The laryngoscope 3 is fixedly connected to the adjusting rod 26 via a rotating plate 31 arranged at the end.

[0031] The connecting sleeve 22 and the fixing seat 21 are connected by a spiral rotation mode. The adjusting rod 26 and the fixing face gear 23 and the connecting sleeve 22 can be connected by a bearing to achieve the relevant rotation connection.

[0032] A circular groove 241 is provided on one side of the movable face gear 24, and the circular groove 241 provides a clear positioning for the spring 25, ensuring that the spring 258 can be stably located at a predetermined position during operation to prevent the spring from being offset or misplaced. A rotating handle 261 is provided at one end of the adjustment rod 26.

[0033] A scale mark 221 is provided on the outer end surface of the connecting sleeve 22. An indicator mark 311 is provided on the rotating plate 31. By rotating the rotating handle 261 and observing the scale mark 211 on the outer end surface of the connecting sleeve and the indicator mark 311 on the rotating plate 31, the medical staff can accurately adjust the angle of the laryngoscope 3. This design not only improves the accuracy of the operation, but also facilitates the recording of the angle, which provides reliable research data in medical records and clinical research.

[0034] The support plate 312 is rotatably installed on the end surface of the rotating plate 31 through a hinge mechanism. There is a support plate 312 installed through a hinge mechanism on the end surface of the rotating plate 31. When the adjusting rod 26 rebounds, the support plate 312 can be rotated and abutted against the connecting sleeve 22. This can prevent the angle of the laryngoscope 3 from changing due to accidental contact with the rotating handle 261, thereby improving the safety of operation.

[0035] The laryngoscope 3 is provided with an illumination device 32, which is helpful for medical staff to clearly observe the patient's throat condition.

[0036] Example 2

[0037] The working process of the utility model is as follows:

[0038] When the medical staff first rotates the support plate 312 to open it, and then presses the rotating handle 261, the adjusting rod 26 will make the movable face gear 24 disengage from the fixed face gear 23. By rotating the rotating handle 261, the angles of the movable face gear 24, the adjusting rod 26 and the laryngoscope 3 will rotate. There is a scale mark 221 on the outer end surface of the connecting sleeve 22. The medical staff can accurately adjust the rotation angle by observing the indicator 311 on the rotating plate 31; once the angle is adjusted and the rotating handle 261 is released, the spring 25 installed between the fixed seat 21 and the movable face gear 24 will rebound, so that the movable face gear 24 and the fixed face gear 23 are re-engaged to form a self-locking, and then the support plate 312 is rotated to close, thereby fixing the selected angle. This improves the efficiency of angle adjustment, and the throat of patients in different postures can be observed without disassembling the laryngoscope.
