[0031] like Figures 1-5 As shown, the disposable medical vaginal speculum disclosed in this embodiment includes a speculum body 1 and a focusing and magnifying component 2. The speculum body 1 has a dilator for dilating the vaginal opening and an observation port for convenient observation. The focusing and magnifying component 2 is disposed at the observation port of the speculum body 1 and is used to magnify the image inside the vagina and adjust the focus to make the image inside the vagina clearer. In specific implementation, the vagina is dilated by the speculum body 1. Due to the presence of the focusing and magnifying component 2, not only can the vaginal image be magnified, but the clarity of the observed image can also be adjusted, significantly improving image clarity and ease of operation, and has important clinical application value.

[0032] Please refer to Figures 3-5 The focusing and magnifying assembly 2 includes an outer cylinder 21, a plano-convex lens 22, a biconvex lens 23, and an inner cylinder 24. The outer cylinder 21 is positioned at the observation port. The plano-convex lens 22 is located inside the outer cylinder 21 near the observation port, with its convex surface facing the port. The biconvex lens 23 is located inside the outer cylinder 21 away from the plano-convex lens 22 and can move back and forth relative to it. In this embodiment, the assembly of the outer cylinder 21 with the vaginal speculum body 1 serves to fix the individual lenses. The plano-convex lens 22 and the biconvex lens 23 form an adjustable magnifying lens group. The biconvex lens 23, also known as a magnifying lens, primarily magnifies the observed tissue, thereby improving the clarity of the observation. In practical use, the relative distance between the plano-convex lens 22 and the biconvex lens 23 can be adjusted to improve image clarity, facilitating examination by the physician.

[0033] In this embodiment, the inner cylinder 24 is embedded in the inner wall of the outer cylinder 21 and can rotate and extend relative to the outer cylinder 21. The biconvex lens 23 is disposed on the inner wall of the inner cylinder 24. Specifically, the inner cylinder 24 has multiple oblique waist holes 241 on its side, and the outer cylinder 21 has multiple pins 211 on its side. Each pin 211 passes through the outer cylinder 21 and is inserted into the corresponding oblique waist hole 241. Four oblique waist holes 241 and four pins 211 are provided to improve the stability of the rotational movement of the inner cylinder 24. During adjustment, the oblique waist holes 241 and the pins 211 provide guidance for the back-and-forth movement of the biconvex lens 23, thereby adjusting the relative distance between the biconvex lens 23 and the plano-convex lens 22, thus achieving the purpose of adjusting the focal length.

[0034] Preferably, the inner side of the outer cylinder 21 is provided with a first annular step 212 for installing the plano-convex lens 22, and the inner side wall of the inner cylinder 24 is provided with a second annular step 242 for installing the biconvex lens 23. The lens is installed through the steps, which facilitates disassembly.

[0035] In addition, a connecting ear 213 is provided at one end of the outer cylinder 21, and the end of the connecting ear 213 away from the outer cylinder 21 is hinged to the observation port of the vaginal speculum body 1. In this embodiment, two connecting ears 213 are provided, and the two connecting ears 213 are symmetrically arranged on the outer cylinder 21 to improve the stability of the outer cylinder 21 during installation. Since the connecting ear 213 is hinged to the vaginal speculum body 1, the outer cylinder 21 can be rotated during observation to observe images from different angles inside the vagina, thereby increasing the observation range of the images.

[0036] Please refer to Figure 1 and Figure 2 The vaginal speculum body 1 includes an upper jaw 11, a lower jaw 12, and an adjustment component 13. One end of the upper jaw 11 is rotatably connected to one end of the lower jaw 12, and the other end of the upper jaw 11 and the other end of the lower jaw 12 can be freely opened. The freely open end of the upper jaw 11 and the lower jaw 12 is the expansion part, and the rotatably connected end of the upper jaw 11 and the lower jaw 12 forms an observation port. The adjustment component 13 is disposed between the upper jaw 11 and the lower jaw 12 and is used to adjust the size of the opening of the upper jaw 11 and the lower jaw 12. One end of the lower jaw 12 extends downward and is integrally provided with a handle 121.

[0037] In this embodiment, the upper jaw 11 and lower jaw 12 are duckbill-shaped, facilitating vaginal dilation. The surfaces of the upper jaw 11 and lower jaw 12 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 13 to facilitate the physician's observation of the vagina. The upper jaw 11 and lower jaw 12 are connected by a pin, and the connecting ear 213 is connected to the same pin, resulting in a simple structure that is easy to adjust.

[0038] Specifically, the adjustment assembly 13 includes an adjustment plate 131, a rotating shaft 132, an adjustment screw 133, and an adjustment nut 134. The adjustment plate 131 is disposed on the side of the upper brow 11, the rotating shaft 132 is rotatably connected to the side of the lower brow 12, one end of the adjustment screw 133 is disposed on the side of the rotating shaft 132, the other end of the adjustment screw 133 passes through the adjustment plate 131 and extends outward, and the adjustment nut 134 is threadedly connected to the adjustment screw 133. The adjustment plate 131 is provided with a waist hole 1311 for the adjustment screw 133 to pass through.

[0039] During adjustment, the adjusting nut 134 can be rotated, causing it to spiral along the adjusting screw 133. The adjusting screw 133 rotates along the rotation axis 132, causing the adjusting plate 131 to move closer to or further away from the rotation axis 132. This, in turn, moves the upper jaw 11 up or down, adjusting the opening size between the upper jaw 11 and the lower jaw 12. The outer side of the adjusting nut 134 has raised and recessed grooves, which increase the friction between the physician's hand and the adjusting nut 134 during rotation, thus improving the stability of the adjustment. Preferably, a washer 1341 is provided between the adjusting nut 134 and the adjusting plate 131. The washer 1341 increases the friction between the adjusting nut 134 and the adjusting plate 1341, improving the stability of the adjustment lock.

[0040] In summary, this embodiment provides an image focusing and magnification mechanism by setting a focusing and magnification component 2 at the observation port of the vaginal speculum body 1, which significantly improves image clarity and ease of operation and has important clinical application value.
