[0025] An auxiliary device for obstetric and gynecological examination includes an inner ring 1 and an outer ring 2 with a concentric structure. The outer ring 2 is fitted outside the inner ring 1, and the outer ring 2 and the inner ring 1 are rotatably connected. The middle part of the inner ring 1 is hollow for doctors to perform examinations and other operations. The inner sides of the outer ring 2 and the inner ring 1 are smoothly aligned. To ensure stable rotation, a groove 11 is provided on the outer wall of the inner ring 1, and a protrusion 21 that cooperates with the groove is provided on the inner wall of the outer ring 2. Therefore, the rotation of the outer ring 2 and the inner ring 1 can be made more stable through the cooperation of the groove 11 and the protrusion 21.

[0026] Multiple triangular arms 3 are arranged in a central array on the rear side of the outer ring 2. In some embodiments, the number of triangular arms 3 can be three. A first rotating shaft 31 and a second rotating shaft 31 are arranged on the triangular arms 3. The first rotating shaft 31 is installed with the inner ring 1 and is rotatably connected. A corresponding sliding groove 22 is provided on the outer ring 2. The sliding groove 22 is arranged in an outwardly expanding state. The second rotating shaft 32 is matched with the sliding groove 22 and can slide in the sliding groove 22. A third rotating shaft 33 is arranged at the far end of the triangular arms 3. An expansion plate 4 is arranged on the outside of the third rotating shaft 33 and is rotatably connected to the third rotating shaft 33.

[0027] An internal gear structure 23 is provided on the outer side of the inner wall of the outer ring 2. A gear 12 is installed on the inner ring 1. The gear 12 and the internal gear structure 23 are engaged. A knob 13 is arranged at the outer end of the gear 12. A knob handle 14 is arranged at the rear end of the knob 13. The knob handle 14 and the knob 13 are arranged by a magnetic attraction and buckle structure. Therefore, when rotation is required, the knob handle 14 and the knob 13 are engaged by the magnetic attraction and buckle structure, which allows the doctor to rotate the gear 12. When performing examinations or other operations, the knob handle 14 can be removed to reduce interference with the examinations or other operations.

[0028] A pawl mechanism 15 is arranged on the inner ring 1. The front end of the pawl mechanism 15 cooperates with the internal tooth structure 23. The front end of the pawl mechanism 15 is a straight structure and the rear end is a sloping structure. The pawl mechanism 15 is fixedly installed with the inner ring 1 through the spring plate structure at its rear end. Under the spring plate structure, it is forced to always be in contact with the internal tooth structure 23. Therefore, under the restriction of the pawl mechanism 15, the outer ring 2 can smoothly rotate counterclockwise on the inner ring 1, but it is restricted to rotate clockwise.

[0029] Between the spring mechanism and the internal gear mechanism is a release knob 16, which is similar to an eccentric wheel structure. The release knob 16 is used to actuate the spring and separate the pawl mechanism 15 from the internal gear mechanism 23, thus allowing the outer ring 2 and the inner ring 1 to rotate freely. The doctor can operate it using the handle of the release knob 16.

[0030] To improve the convenience of inspection and other operations, multiple lighting lamps 17 are arranged on the inner side of the inner ring component. The lighting lamps 17 can be spotlight LED lamps, which are connected to a power supply and a switch for easy use.

[0031] The three expansion plates 4 are used to insert into the patient's examination site and expand it. The front end of the expansion plate 4 is an arc structure. In the initial state, the three expansion plates 4 are just in contact and the whole is similar to a cylindrical structure. The arc structure at the front end can form a hemispherical structure, so it will be smooth to enter the patient's examination site and reduce the patient's foreign body sensation.

[0032] To improve examination efficiency, the expansion plate 4 is made of transparent plastic or acrylic sheet in one piece. The rear end of the expansion plate 4 has an arc-shaped flange 41, which can reduce the patient's body contact with structural components such as the inner ring 1 or the outer ring 2.

[0033] The expansion plate 4 can provide disposable aseptic packaging for better hygiene assurance, while structural components such as the inner ring 1 or outer ring 2 can be made of engineering plastics or stainless steel and can be reused under standard sterilization conditions to reduce unnecessary material waste.

[0034] In actual operation, the three triangular arms 3 are brought into a converged state by the knob handle 14, and the three expansion plates 4 are also arranged in a cylindrical structure. Under the doctor's operation, the expansion plates 4 are placed into the area to be examined by the patient. Then, the outer ring 2 is driven to rotate by the knob handle 14, which drives the three expansion plates 4 to open outward, thus expanding the part to be examined, making it easier for the doctor to perform the corresponding examination and other operations. When the examination is completed, the doctor releases the knob 16 to bring the three expansion plates 4 into a converged state.

[0035] In summary, the main body of the obstetric and gynecological examination auxiliary device of this solution adopts a rotary expansion structure. The expansion operation of the expansion plate is achieved by the cooperation of gears and internal gears to drive the outer ring and triangular arm. The whole operation is convenient and precise. After expansion, a spacious and unobstructed examination channel is built at the center of the inner ring, which facilitates the doctor to perform precise examination operations.

[0036] This solution uses a ratchet mechanism to control the rotation of the outer ring, thereby fixing the opening position of the expansion plate. When the doctor adjusts it to the appropriate position, it can stably maintain this state to facilitate the doctor's subsequent examination operations. When the examination is completed, the expansion plate can be returned to its original position by releasing the knob, making it easy to exit the operation.

[0037] This structure allows for internal illumination via a light source at the inner ring, greatly improving the convenience of examinations and making them simpler and more efficient for doctors. The design is simple in structure, easy to operate, and has significant potential for wider adoption.
