Description

Technical Field

[0001] This utility model belongs to the field of medical devices and relates to a gynecological examination instrument, particularly to a dilator for an electronic vaginal examination instrument. Background Technology

[0002] A speculum used in gynecological examinations, also known as a vaginal speculum or speculum, is primarily used to assist in dilating the vagina during gynecological examinations to expose the vaginal walls and cervix for sampling and observation. A speculum typically consists of an upper speculum, a lower speculum, and an adjustment mechanism for opening and closing the upper and lower speculum. During use, the upper and lower speculum are closed and inserted into the vaginal structure. The adjustment mechanism is then used to open and position the upper and lower speculum. After the examination, the speculum is removed by reversing the procedure.

[0003] Current electronic vaginal examination devices use electronic sensors such as cameras to visually capture images of the vaginal wall and cervix for diagnostic purposes. Cameras are typically located at the rear ends of the upper and lower dilators. In existing designs, the camera is fixed to the rear extension of the lower dilator. Figure 1 As shown, in order to ensure a clear field of view for the camera, a glass lens 5 is usually embedded in the partition 4 at the position corresponding to the camera. This not only increases the overall cost, but also makes it difficult to completely seal the embedded part of the glass lens. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing dilators used in electronic vaginal examination devices have glass lenses embedded in the partition in front of the camera, which increases the overall cost and makes it difficult to achieve a seal. The invention provides a dilator for electronic vaginal examination devices that uses a high-transparency plastic one-piece molded partition in front of the camera. This reduces the cost while meeting the requirements for camera field of view clarity, and also allows for a complete seal at the partition.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electronic vaginal examination device dilator, including an upper dilator and a lower dilator, the rear ends of the upper dilator and the lower dilator are hinged to each other, the rear end of the lower dilator is connected to a hand-held part, the top front side of the hand-held part is provided with an isolation plate, the isolation plate is integrally molded from transparent plastic material, and a camera is provided on the rear side of the isolation plate.

[0006] The handheld part of this device features a one-piece molded top structure, providing excellent waterproof sealing and solving the problem of handheld part disinfection. The isolation plate is made of high-transparency plastic, which meets the camera's field-of-view clarity requirements while saving on the material and installation costs of glass plates.

[0007] Preferably, the top surface of the handheld part has a herringbone-shaped closed structure that is higher in the middle and lower at the front and back. The isolation plate is set on the top front side of the handheld part and is inclined relative to the handheld part, so that it can maintain a relatively perpendicular angle with the front end of the upper and lower expansion plates, so that the camera has a better field of view.

[0008] Preferably, the included angle between the lower expansion piece and the handheld part is 100-150°.

[0009] Preferably, the isolation plate is perpendicular to the central axis of the camera.

[0010] Preferably, the lower dilator has a snap-fit ​​sleeve at its rear end, which detachably engages with the handle. The snap-fit ​​sleeve has a hollow center, and the isolation piece at the top of the handle extends from the hollow center. Both the lower and upper dilators are disposable instruments, ensuring a medical-grade hygiene standard. The handle does not enter the body and is designed for reusability, connecting to the electrical components of the electronic vaginal examiner, thus saving examination costs. The lower dilator's snap-fit ​​connection to the handle allows for quick replacement.

[0011] Preferably, the rear end of the upper expansion piece is provided with an extension portion, and the extension portion is hollowed out in the middle to form an observation window.

[0012] Preferably, the rear end of the upper expansion piece is provided with an extension portion, the rear end of the extension portion is provided with a locking hole, the rear end of the lower expansion piece is provided with a locking sleeve, the rear side of the locking sleeve is provided with an elastic locking head corresponding to the locking hole, the elastic locking head is provided with a locking limiting block with multiple positions that engage with the wall of the locking hole, and the rear end of the elastic locking head is also provided with a release pressing piece.

[0013] Preferably, both the upper and lower expansion plates are symmetrically arranged. Since the upper and lower expansion plates are aligned horizontally, they can be operated by either hand.

[0014] The top of the handheld part of this expander is made of transparent plastic material in one piece, which reduces production costs while ensuring the clarity of the camera's field of view, and makes the sealing more reliable and convenient for disinfection of the handheld part after repeated use.
