Disposable smoke-discharging type double-protective wing vaginal dilator and preparation thereof

Abstract

The invention relates to a disposable smoke removal double-wing vaginal speculum and a manufacturing method thereof, wherein an upper expanding arm is connected with an upper blade into a whole and a lower expanding arm is connected with a lower blade into a whole; the upper expanding arm and the lower expanding arm are hinged with each other around a shared pin shaft and are positioned by positioning rods; front edges of the upper blade and the lower blade have smooth duckbill structures without seamed edges; the inside of the upper blade is provided with a smoke extracting tube which is communicated with a smoke extracting device; and the upper blade and the lower blade are provided with elastic silica gel sleeve wings or elastic aliform wings or concertina folding wings. The front edges of the upper blade and the lower blade of the disposable smoke removal double-wing vaginal speculum have the smooth structures without the seamed edges, thereby the disposable smoke removal double-wing vaginal speculum can avoid contact damage and hemorrhage and is safe and reliable; the smoke extracting tube can remove electrical burn smog in an operation, thereby the visual field is clear and environmental pollution is prevented; and the wings on both sides of the vaginal wall can effectively prevent the accidental injury accidents of electrodes on the vaginal wall, and are helpful to pump and remove the electrical burn smog generated during the process of the operation.

Description

technical field [0001] The invention relates to a gynecological medical device, in particular to a disposable smoke-exhausting double-wing vaginal dilator and a manufacturing method thereof. Background technique [0002] Disposable vaginal dilators in obstetrics and gynecology have been in clinical use for more than ten years. In recent years, with the rapid popularization of electronic colposcopy, the positive diagnosis rate of women's cervical diseases has increased rapidly. A considerable number of patients need cervical surgery, and "LEEP" (Loop Electrode Circumcision of Precancerous Lesions of Cervix) surgery is one of the most common surgical procedures in clinical practice. "LEEP" surgery, like other cervical surgery, is inseparable from the good exposure of the surgical field and visual field. Moreover, the ring electrode used in the "LEEP" operation is relatively large, which is easily formed after the upper and lower blades of the traditional vaginal dilator are o...

Problems solved by technology

From the clinical use, it is often found that when the arc-shaped tip of the mouth touches the eroded cervix, the arc-shaped top of the front edge of the upper and lower pieces of the duck mouth is easy to touch the patient's cervix and cause bleeding, which directly affects the examination and treatment of the surgeon.
