Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a vaginal expander. Background Technology
[0002] A vaginal speculum, also known as a vaginal dilator, is a device used for routine gynecological examinations and surgeries. It opens the patient's vulva to facilitate examination and treatment. In patients with vaginal inflammation or ulcers, some of the lesions are located close to the vaginal opening. When using infrared therapy, the patient's private parts need to be opened, which lacks sufficient support. To facilitate subsequent care and support of the vagina, a vaginal dilator is needed.
[0003] However, existing vaginal dilators have the following disadvantages:
[0004] (1) Existing vaginal dilators have weak adaptability. Because different patients have different vaginal sizes and shapes, and traditional dilators are difficult to adjust their size and model, they are difficult to adapt to different patients.
[0005] (2) Existing vaginal dilators have limited practical functions. Due to the limited functionality of traditional dilators, it is difficult for medical staff to operate and control the depth and angle of the dilators. Utility Model Content
[0006] The purpose of this invention is to provide a vaginal expander to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a vaginal expander, comprising a frame, a fixing ring fixedly connected to the inner top wall of the frame, a connecting ring fixedly connected to one side of the fixing ring, an installation block snapped into the inside of the connecting ring, an expansion plate fixedly connected to one side of the installation block, a guide plate fixedly connected to one end of the expansion plate, a lubricating layer provided on the outer surface of the guide plate, a handheld frame fixedly connected to the bottom side of the frame, and an anti-slip pad fixedly connected to the outer surface of the handheld frame.
[0008] Optionally, a rectangular plate is fixedly connected to the inner sidewall of the frame. An adjusting screw is threadedly connected to the inside of the rectangular plate. A nut is fixedly connected to the bottom of the adjusting screw. An adjusting slider is threadedly connected to the outer surface of the adjusting screw. A support rod is fixedly connected to the top of the adjusting slider. An adjusting ring is fixedly connected to the top of the support rod. Rotating the nut causes the adjusting screw to rotate. The rotation of the adjusting screw causes the adjusting slider and the support rod to move. The movement of the support rod causes the adjusting ring to move, thereby adjusting the size of the expansion.
[0009] Optionally, a connecting groove is provided on the side of the adjusting ring, and a limiting slider is fixedly connected inside the connecting groove. The connecting groove supports and fixes the limiting slider to the adjusting ring. The limiting slider can limit the position of the adjusting ring and prevent the position of the adjusting ring from shifting.
[0010] Optionally, a limiting groove is provided on the inner side wall of the frame, and the limiting slider fits into the limiting groove. When the limiting slider slides inside the limiting groove, the limiting groove limits the limiting slider to prevent the limiting slider from deviating from its sliding position.
[0011] Optionally, a connecting plate is fixedly connected to the inner bottom wall of the frame, and a connecting groove is provided on one side of the connecting plate. The connecting groove can limit the movement of the connecting slider.
[0012] Optionally, a connecting slider is fixedly connected to the side of the adjusting slider. The connecting slider fits into the connecting groove. When the connecting slider slides inside the connecting groove, the connecting groove limits the connecting slider, thereby limiting the adjusting slider.

[0014] 1. This vaginal dilator, through the configuration of a fixing ring, a connecting ring, a mounting block, and an expansion plate, allows for easy installation and replacement of the expansion plate. The fixing ring supports and secures the connecting ring. When the mounting block is inserted into the groove inside the connecting ring, the connecting ring limits the mounting block's position, fixing it within the groove and thus securing the expansion plate. This improves the device's adaptability, avoiding the limitations of traditional dilators that are difficult to adjust in size and model to accommodate different patients' vaginal sizes and shapes.
[0015] 2. This vaginal dilator, through the design of a guide plate, lubrication layer, handheld frame, and anti-slip pad, features a semi-circular guide plate that guides and dilates the vagina when inserted. The lubrication layer is made of silicone-based lubricant, maintaining lubrication for a longer period and reducing patient discomfort. Medical staff can hold the handheld frame, and the anti-slip pad, made of rubber, prevents the device from slipping, thus improving its practicality. This avoids the problem of traditional dilators having limited functionality, making it difficult for medical staff to operate and control the depth and angle of the dilator.
