[0027] like Figures 1-3 As shown, this embodiment discloses a disposable light-guided vaginal speculum, including an upper jaw 1, a lower jaw 2, an adjustment component 3, and a light-guided component 4. One end of the upper jaw 1 is rotatably connected to one end of the lower jaw 2, and the other end of the upper jaw 1 and the other end of the lower jaw 2 can be freely opened. The adjustment component 3 is disposed between the upper jaw 1 and the lower jaw 2 to adjust the size of the openings. One end of the lower jaw 2 extends downward and is integrally provided with a handle 21. The light-guided component 4 is disposed on the lower jaw 2 and is used to collect light from an external light source and reflect it to the other end of the lower jaw 2 to illuminate the vagina.

[0028] In this embodiment, the upper jaw 1 and lower jaw 2 are duckbill-shaped, facilitating vaginal dilation. The surfaces of the upper jaw 1 and lower jaw 2 that contact the vaginal wall are smooth arc-shaped, improving patient comfort. In actual use, the upper and lower jaws are inserted into the vagina, and the opening size of the upper and lower jaws is adjusted by the adjusting component 3 to facilitate the doctor's observation of the vagina. The light guide component 4 is located at the bottom of the handle 21. At this time, the light guide component 4 is located outside the vagina, connecting to an external light source. The external light source is then guided into the vagina through the light guide component 4, thereby illuminating the vaginal wall and facilitating the doctor's observation. Passive lighting technology is used, eliminating the need for an external power supply for lighting, saving resources, simplifying operation, and improving lighting efficiency.

[0029] Preferably, the light guide assembly 4 includes a light-collecting part 41, a light guide tube 42, and a light-diffusing part 43. The light-collecting part 41 is located at the bottom of the handle 21 and is used to collect external light sources. The light guide tube 42 extends from the bottom of the handle 21 to the other end of the lower jaw 2. The light-diffusing part 43 is located at the other end of the light guide tube 42. The light collected by the light-collecting part 41 is reflected by the light guide tube 42 and then scattered by the light-diffusing part 43 to illuminate the vagina. Specifically, the light-collecting part 41 collects external light sources, which are then refracted by the light guide tube 42 and enter the light-diffusing part 43. The light-diffusing part 43 scatters the refracted light, thus providing omnidirectional illumination of the vagina. This facilitates examination by the physician without requiring adjustment of other structures or lighting angles, and does not obstruct the physician's view, thereby improving examination efficiency.

[0030] Please refer to Figure 3 The light-collecting part 41 includes a light-collecting spherical surface 411, a reflective mirror 412, a first connecting part 413, and a hemispherical mirror 414. Specifically, the light-collecting spherical surface 411 and the reflective mirror 412 are integrally formed. The reflective mirror 412 is inclined at a 45° angle. The first connecting part 413 is located on the top of the light-collecting spherical surface 411, and the hemispherical mirror 414 is located on the top of the first connecting part 413. The light collected by the light-collecting spherical surface 411 is reflected by the reflective mirror 412 and then focused by the hemispherical mirror 414 before finally entering the light guide tube 42. During lighting, the light-collecting spherical surface 411 collects external light sources, which then enter the light-collecting section 41 and strike the reflecting mirror 412. After reflection by the reflecting mirror 412, the light strikes the hemispherical mirror 414, which focuses the reflected light. The focused light then enters the light guide tube 42, where it is refracted before finally striking the scattering section 43. The reflecting section 43 scatters the light refracted from the light guide tube 42, thus providing omnidirectional illumination of the vagina. In this embodiment, the scattering section 43 is an astigmatic mirror.

[0031] Preferably, a second connecting part 421 is provided at the bottom of the light guide tube 42, and the second connecting part 421 is connected to the first connecting part 413. The light guide tube 42 is connected to the light-collecting part 41 through the first connecting part 413 and the second connecting part 421, simplifying assembly and disassembly. Specifically, the first connecting part 413 is integrally formed with the light-collecting sphere 411, and the second connecting part 421 is integrally formed with the light guide tube 42, making the device more stable and simplifying installation. Specifically, the first connecting part 413 is an externally threaded tube, and the second connecting part 421 is an internally threaded sleeve. The internally threaded sleeve is threadedly connected to the externally threaded tube, and the light guide tube 42 is connected to the light-collecting part 41 through this threaded connection, making assembly and disassembly even faster.

[0032] In this embodiment, the light guide tube 42 is an acrylic tube with phosphor evenly distributed inside. During light transmission, the phosphor is excited to emit light using the light properties of the light guide tube 42, which reduces light loss and increases light reflection performance, resulting in uniform light output. Furthermore, the inner wall of the light guide tube 42 is coated with light-guiding silicone. The light-guiding silicone increases light guiding efficiency and reduces light loss at bends.

[0033] Specifically, the adjustment assembly 3 includes an adjustment plate 31, a rotating shaft 32, an adjustment screw 33, and an adjustment nut 34. The adjustment plate 31 is located on the side of the upper jaw 1, the rotating shaft 32 is rotatably connected to the side of the lower jaw 2, one end of the adjustment screw 33 is located on the side of the rotating shaft 32, and the other end of the adjustment screw 33 passes through the adjustment plate 31 and extends outward. The adjustment nut 34 is threadedly connected to the adjustment screw 33, and the adjustment plate 31 has a slot 311 through which the adjustment screw 33 passes. During adjustment, the adjustment nut 34 can be rotated, causing it to spiral along the adjustment screw 33. This causes the adjustment screw 33 to rotate along the rotating shaft 32, moving the adjustment plate 31 closer to or further away from the rotating shaft 32, thereby causing the upper jaw 1 to move upward or downward, thus adjusting the size of the opening between the upper jaw 1 and the lower jaw 2. The outer side of the adjustment nut 34 has raised and recessed grooves, which increase the friction between the physician's hand and the adjustment nut 34 during rotation, thereby improving the stability of the adjustment. Preferably, a washer 341 is provided between the adjusting nut 34 and the adjusting plate 31. The washer 341 can increase the friction between the adjusting nut 34 and the adjusting plate 341 and improve the stability of the adjustment and locking.

[0034] In summary, this embodiment uses the light guide component 4 to directly connect an external light source to the inside of the patient's vagina for illumination. It adopts passive lighting technology, eliminating the need for an external power supply, saving resources, simplifying operation, and improving lighting efficiency.
