Tunnel Disposable Sterile Vaginal Dilator

Abstract

The invention relates to a tunnel-type disposable sterile vaginal dilator. The tunnel-type disposable sterile vaginal dilator comprises an upper dilation vane, a lower dilation vane, a push rod, an arc light guiding column, a light source and an assisted dilation mechanism, wherein an adjusting mechanism is arranged at the top end of the push rod; the arc light guiding column and the light source are arranged on the lower dilation vane; a light output end of the light source is supported against the arc light guiding column; the upper dilation vane is provided with an exhaust structure used for exhausting smoke in the vaginal cavity; the exhaust structure consists of a connecting pipe and an exhaust groove; slide rails are arranged on two sides of the exhaust groove, slide ways matched with the slide rails are formed in the upper dilation vane, and the exhaust structure is detachably connected with the upper dilation vane due to matching of the slide rails and the slide ways; the assisted dilation mechanism consists of a first dilation piece and a second dilation piece, either of the first dilation piece and the second dilation piece consists of a dilation part, a spacing part and an assembly part; the first dilation piece and the second dilation piece are detachably connected by means of matching of the assembly parts, and the dilation parts are folded or unfolded due to matching of the spacing parts. The tunnel-type disposable sterile vaginal dilator has the advantages of reasonable structure design, convenience in use and good reliability.

Description

technical field [0001] The invention relates to a tunnel-type disposable aseptic vaginal dilator, which belongs to the technical field of medical devices. Background technique [0002] At present, disposable vaginal dilators are often used in clinical gynecological examinations. The current vaginal dilator is a very thin duckbill clip. The doctor places it in the patient's vagina and opens the entire clip, and then uses the examination light or fingers or instruments to cooperate with the inspection. , when the lesion is found, smoke will be generated in the vaginal cavity during the operation process. Due to the unreasonable structural design of the existing dilator, the smoke is difficult to get rid of in time, which affects the doctor's diagnostic vision. The doctor can only operate by hand or experience , the diagnosis process takes a long time, which brings great pain to the patient. For diseases that require visual diagnosis, it will lead to inaccurate judgment and eas...

[0002] At present, disposable vaginal dilators are often used in clinical gynecological examinations. The current vaginal dilator is a very thin duckbill clip. The doctor places it in the patient's vagina and opens the entire clip, and then uses the examination light or fingers or instruments to cooperate with the inspection. , when the lesion is found, smoke will be generated in the vaginal cavity during the operation process. Due to the unreasonable structural design of the existing dilator, the smoke is difficult to get rid of in time, which affects the doctor's diagnostic vision. The doctor can only operate by hand or experience , the diagnosis process takes a long time, which brings great pain to the patient. For diseases that require visual diagnosis, it will lead to inaccurate judgment and easily lead to accidents in surgery. In addition, surgical smoke consists of 95% water vapor and 5% particle form Composed of cell fragments, the existence of particles makes surgical smoke a serious hazard to human health, and medical staff sometimes feel dizzy, headache, nausea and other discomfort symptoms

[0003] At present, vaginal dilators with built-in lighting sources have also appeared on the market. They use dry batteries as the power source, which is not conducive to disinfection. Dry batteries have potential safety hazards of explosion in the patient's body.

In addition, the vaginal dilator in the prior art also has the following disadvantages: the adjustment controllability between the upper and lower expansion leaves is poor, and it is inconvenient to use. After the upper and lower expansion leaves are opened, the upper and lower sides of the patient's vaginal cavity wall can be It is well stretched, but the cavity walls on the left and right sides are converging, which interferes with the doctor's diagnostic vision, and it is impossible to avoid the accumulation of smoke in the cavity, and the structural design between the upper and lower expansion leaves is unreasonable, and the reliability is poor when used. It is easy to cause accidental injury, the size of the upper and lower expansion leaves is too long, it is easy to cover the cervix, and the width of the operating surface is not enough, which restricts robotic surgery or suture after surgery
