Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, in particular to an improved smoke exhaust pipe speculum. BACKGROUND

[0002] The speculum is a medical device used for vaginal speculum examination. For vaginal speculum examination, the vagina of a woman is very deep, and its outer end is the labia majora and the inner end is the cervix. They are often in a closed state. If you want to check whether there is a lesion in the vagina and the cervix, you must use the speculum to open the labia majora and the vagina until the cervix and the surrounding vaginal vault are exposed, and then check from inside to outside.

[0003] According to the search of the patent file CN 203000893 U, the anti-slip speculum belongs to medical devices and is composed of a speculum and a perineal pad. The speculum is composed of an upper jaw piece and a lower jaw piece connected by a shaft. The upper jaw piece and the lower jaw piece are provided with clamping grooves. The perineal pad is provided with a tight opening in the middle. The upper jaw piece and the lower jaw piece pass through the tight opening, and the tight opening and the clamping grooves are connected. The anti-slip speculum has the advantages of avoiding repeated slipping of the speculum, reducing the damage and infection of the patient's vagina caused by insertion, ensuring the safety and hygiene during gynecological surgery, treatment and examination, and improving the work efficiency of medical personnel.

[0004] However, the inventor has found that the technical solution still has at least the following defects:

[0005] Most of the speculums used by the patient group, such as women who have not given birth, have given birth, and are postpartum or extremely relaxed due to obesity, are used to open the upper and lower jaws by the handle for examination. However, for patients who have not given birth, are obese, or have a small vaginal orifice, the position of the vaginal orifice is easily damaged and causes discomfort to the patient as the upper and lower jaws are opened. CONTENT OF THE UTILITY MODEL

[0009] In a preferred embodiment, the secondary expansion mechanism comprises a memory alloy, the right side of the memory alloy is provided with an expansion plate, the lower end of the expansion plate is fixedly connected with a rubber rope, the end of the rubber rope away from the expansion plate is slidably connected with a fixed block through the expansion plate, the memory alloy and the upper jaw piece, the lower end of the fixed block is fixedly connected with the upper end of the lower jaw piece, the left side of the handle is provided with a pressing handle, and the end of the rubber rope away from the expansion plate is provided with a running knot through the pressing handle.

[0010] By adopting the above technical scheme, the tightness of the expansion plate can be adjusted by adjusting the position of the running knot.

[0011] In a preferred embodiment, the lower end of the protective transparent cover is fixedly connected with a transparent supporting strip, and the upper end of the lower jaw piece is fixedly connected with a double-sided LED lamp sheet in the middle.

[0012] By adopting the above technical scheme, the transparent supporting strip can support and fix the protective transparent cover, and the light inside is convenient to penetrate.

[0013] In a preferred embodiment, the right two ends of the memory alloy are fixedly connected with clamping blocks, the left side of the expansion plate is fixedly connected with a connecting strip, the opposite inner sides of the clamping blocks are fixedly connected with rotating anti-disengagement rods, and the connecting strip is rotatably connected with the rotating anti-disengagement rods.

[0014] By adopting the above technical scheme, the expansion plate can be upwardly supported through the rotation of the connecting strip and the rotating anti-disengagement rod.

[0015] In a preferred embodiment, the penetration path of the rubber rope is out of the bottom end of the expansion plate, into the upper end of the expansion plate, out of the bottom end of the memory alloy, into the upper end of the memory alloy and the upper jaw piece, and into the pressing handle after penetrating through the fixed block.

[0016] By adopting the above technical scheme, after the rubber rope is fastened, the expansion plate can be moved upward by pressing the pressing handle, and the inside of the vagina can be expanded for the second time.

[0017] Therefore, by adopting the technical scheme, the application has the beneficial effects:

[0018] In the application, the speculum is placed in the vagina, the lower jaw piece and the upper jaw piece are spread apart, the size of the spread can be adjusted according to the patient's acceptance, then the inside of the vagina can be brightened by the double-sided LED sheet, which is convenient for observation, when the muscle of the inner wall of the vagina blocks the line of sight, the handle can be pressed to drive the rubber rope to move down, thereby driving the expansion plate to be supported upward, the inner wall of the vagina can be expanded again, which is convenient for checking the inside of the vagina, at the same time, when the speculum and the inner wall rub and contact, some smoke or gas may be generated, which can be discharged outside the body through the smoke exhaust pipe, avoiding the accumulation of smoke in the examination or operation area, affecting the doctor's vision or the patient's comfort; through the cooperation of the above structure, it can be suitable for different people and reduce the discomfort during examination.
