Description

Technical Field

[0001] The present invention relates to the technical field of vaginal and cervical examinations, and particularly to a visual vaginal and cervical examination instrument. Background Art

[0002] The vagina is a muscular duct composed of mucosa, muscular layer and adventitia, which is highly stretchable and connects the uterus and external genitalia. It belongs to the female internal reproductive organs, is the sexual intercourse organ of women, and is also the duct for discharging menstrual blood and delivering the fetus. The cervix is at the end of the vagina, also known as the uterine cervix, and can have various diseases, including many obstetrics and gynecology problems such as abnormal embryonic development, inflammation, tumor-like lesions, benign tumors, malignant tumors, injuries, cervical infertility, family planning, assisted reproductive technology, cervix and sex, cervical pregnancy, cervical dystocia, etc. The uterine cervix is an important defense line to prevent pathogens from entering the internal reproductive organs, but it itself is also under the attack of various pathogenic factors; and there are many cervical endometrial fissures, and it is difficult to eliminate bacteria lurking here, which is extremely easy to cause cervical inflammation. Therefore, it is very necessary for women to have regular gynecological examinations. When examining the vagina and cervix, there are the following disadvantages: 1. When the probe of the existing examination device extends into the vagina and cervix, it is troublesome to turn, and it is easy to hurt the cervix and cause secondary injury to the cervix; 2. After the probe of the examination device extends into the vagina and cervix, the distance between the vaginal wall and the probe is too small, resulting in a blurred picture taken by the probe.

[0016] Advantageous Effects

[0017] Compared with the prior art, the present invention provides a visual vaginal and cervical examination instrument, which has the following advantageous effects:

[0018] 1. For this visual vaginal and cervical examination instrument, by rotating the rotating handle, the sliding ring on the rotating cylinder can be driven to rotate inside the sliding opening of the mounting cylinder. At this time, the clamping groove inside the rotating cylinder will drive the sliding rod, so that the pulling shaft rotates with the rotating cylinder. The sliding rod can be clamped by the clamping groove, thereby fixing the moving path of the pulling shaft and preventing the pulling shaft from deflecting, which may cause the probe to deflect and affect shooting. The rotating rod can be clamped by the opening, so that the probe can rotate with the rotating cylinder. Through the observation port, the probe can conveniently take pictures, preventing the protection plate from affecting the probe shooting. Pull the pulling cap to slide the inserting block out of the socket, and at the same time drive the pulling shaft to move. The inserting block can be clamped by the socket, thereby fixing the pulling cap and preventing the pulling shaft from being damaged when the pulling cap is collided. The rear end of the rotating rod will rotate inside the rotating opening and move backward, and at the same time drive the torsion spring outside the third connecting shaft to deflect. The front end of the rotating rod will rotate inside the opening, so that the probe rotates forward, enabling the probe to take pictures of the front end of the vagina and cervix. The torsion spring will drive the rotating rod to return, and during the return process of the rotating rod, it will hit the pressing block, causing the pressing block to compress the limiting spring and push the sliding plate to slide inside the sliding groove. The rotating speed of the rotating rod can be slowed down by the pressing block, preventing the internal components from being damaged due to excessive vibration of the probe.

[0019] 2. This kind of visualized vaginal and cervical examination instrument can stretch the vaginal and cervical through the guard plate, and the probe can more clearly capture the inner wall of the vaginal and cervical. By pressing the handle, the guard plate will drive the shaft seat to rotate on both sides of the connecting block, so that the front end of the guard plate will be tilted to open the vaginal and cervical. At the same time, the first connecting shaft will drive the spring sheet to contract, and the spring sheet can facilitate the rotation of the guard plate and the recovery of the guard plate. The guard plate can be supported by the block to prevent the guard plate from deflecting too much and causing damage to the probe. At the same time, the rotating block will slide to the outside of the guard plate through the bayonet, and the fixed block will slide into the inside of the bayonet. The rotating block is rotated on the second connecting shaft to press down the guard plate and fix the guard plate, which is convenient for the doctor's subsequent operation.
