[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1

[0024] like Figure 1 As shown, in this embodiment, the electric otoscope with puncture function includes: a puncture component 1 and an electric otoscope body 2.

[0025] The electric otoscope body 2 includes: an observation tube 21 , a handle housing 22 , a battery 23 , a light switch 24 , a power supply circuit 25 , a light emitting body 26 , and a transparent lens 28 .

[0026] The observation tube 21 is a hollow cone-shaped tube with two openings at both ends. A transparent lens 28 is fixed at the opening of the large end of the cone-shaped tube for easy observation, and a light source 26 is fixed at the opening of the small end of the cone-shaped tube. In this embodiment, the light source 26 is an LED electronic light strip.

[0027] Preferably, the electric otoscope body 2 may further include a convex mirror 27. The convex mirror 27 and the upper end of the observation tube 21 are rotatably connected through a hinge 27a, and are close to the large end of the cone. The junction 27a can extend out of the observation tube 21, and by moving this part, the position of the convex mirror 27 can be adjusted, and the observation angle of the observation tube 21 can be adjusted.

[0028] The middle position of the lower part of the observation tube 21 is connected to the upper end of the handle housing 22. Figure 2 As shown, in this embodiment, the lower part of the observation tube 21 has a connection hole 21c, and a plurality of elastic sheets 21a are evenly distributed around the circumference of the connection hole 21c, and the lower end of the elastic sheet 21a has a barb 21b. The upper end circumference of the handle housing 22 has a corresponding barb groove 22a. The elastic sheet 21a and the barb 21b are inserted into the inner wall of the handle housing 22 until the barb 21b is embedded in the barb groove 22a, so as to realize the connection between the observation tube 21 and the handle housing 22. Of course, the observation tube 21 and the handle housing 22 can be connected by bolts, or other methods such as clamping.

[0029] Preferably, the width of the barb groove 22a is greater than the width of the barb 21b, and is preferably about 2 to 3 times. Therefore, the barb 21b can rotate slightly in the barb groove 22a, so that the angle of the observation tube 21 relative to the handle housing 22 can be slightly adjusted.

[0030] The battery 23, the power supply circuit 25, the light switch 24 and the light emitting body 26 are electrically connected through wires or circuit boards. The battery 23 provides electrical energy and is fixed in the handle housing 22. The power supply circuit 25 receives electrical energy and receives control from the light switch 24 to supply power to the light emitting body 26, and is also fixed in the handle housing 22. The light switch 24 controls the opening and closing of the light emitting body 26 and is installed on the side wall of the handle housing 22. It should be noted that the power supply circuit 25 draws power from the battery, is controlled by the switch, and supplies power to the light emitting body 26, which belongs to the prior art in the field.

[0031] like Figure 1 and Figure 3 As shown, the puncture assembly 1 includes: a driving motor 11, a transmission gear 12, a transmission rack 13, a puncture frame 14, a puncture needle 15 and a puncture switch 16.

[0032] In this embodiment, the driving motor 11 is a stepping motor, which is also fixed in the handle housing 22. The output shaft of the driving motor 11 passes through the connecting hole 21c at the lower part of the observation tube 21 and is fixedly connected to the transmission gear 12, driving the transmission gear 12 to rotate.

[0033] The inner wall of the observation tube 21 is provided with a transmission rack slot and a puncture frame slot. The transmission rack 13 and the puncture frame 14 are embedded in corresponding slots and are slidably connected to the observation tube 21. The transmission gear 12 is meshed with the transmission rack 13. The transmission rack 13 is fixedly connected to the puncture frame 14. The puncture needle 15 is detachably connected to the puncture frame 14.

[0034] The battery 23, the power supply circuit 25, the puncture switch 16 and the driving motor 11 are electrically connected through wires or circuit boards, and the puncture switch 16 can control the forward and reverse rotation of the driving motor 11.

[0035] The puncture switch 16 is moved forward to control the drive motor 11 to rotate forward, driving the transmission gear 12 to rotate, thereby driving the transmission rack 13 to move toward the small end of the observation tube 21, driving the puncture needle 15 to extend out of the small end of the observation tube 21, and completing the tympanic membrane puncture.

[0036] The puncture switch 16 is toggled backward to control the drive motor 11 to reverse, driving the transmission gear 12 to rotate, thereby driving the transmission rack 13 to move into the observation tube 21 and driving the puncture needle 15 to retract into the observation tube 21 .

[0037] It should be noted that the puncture switch 16 and the light switch 24 can be a touch switch, a push switch or a digital display switch, and are not limited to a toggle switch. In addition, the puncture switch 16 and the light switch 24 can be multi-way controlled by the same switch.

[0038] Embodiment 2

[0039] In this embodiment, the electric otoscope body 2 and the driving motor 11 in the puncture assembly 1 rotate forward, and finally drive the puncture needle 15 to extend out of the small end of the observation tube 21, and the structure and working principle of completing the tympanic membrane puncture are the same as those in the first embodiment and will not be repeated.

[0040] In this embodiment, the reverse rotation of the driving motor 11 is not controlled by the switch on the handle housing 22, but by a slight change in the current. The start of the driving motor 11 and the light source 26 share a switch 24.

[0041] The puncture assembly 1 also includes: a conductive sheet 18 and a current sensor 19. The front end 15b of the puncture needle 15 is a non-metallic insulating material, and the rear end surface is coated with a conductive metal coating 15a. The dotted line is the dividing position. Figure 7 The length of the insulating material at the front end of the puncture needle 15 is determined by the depth of the puncture. In this embodiment, the puncture frame 14 is also made of conductive metal material.

[0042] The conductive sheet 18 is fixed on the puncture frame 14, and the two are electrically connected. The rear metal coating 15a of the puncture needle 15 is fixedly connected to the puncture frame 14 and electrically connected. The current sensor 19 plays the role of current amplification and is connected between the conductive sheet 18 and the power supply circuit 25.

[0043] The puncture needle 15, the puncture frame 14, the conductive sheet 18, the current sensor 19 and the power supply circuit 25 form a circuit loop. When the puncture needle 15 punctures the tympanic membrane until the metal coating 15a at the rear end, a part of the current in the circuit is conducted into the human body, and the current sensor 19 senses the current change, triggering the power supply circuit 25 to control the reverse rotation of the drive motor 11, driving the puncture needle 15 to retract into the observation tube 21 and return to its original position. The application of the current sensor 19 as a switching power supply, hard switch, or soft switch, and the power supply circuit 25 to control the reverse rotation of the drive motor 11 are all prior art and will not be elaborated in the present invention.

[0044] The embodiments described above are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
