TECHNICAL FIELD
[0001] The utility model relates to the field of medical apparatus and instruments, especially to a dilator with drainage channel. BACKGROUND
[0002] The vaginal dilator is a medical tool for gynecological examination. Its main function is to open the vaginal wall, so that the doctor can clearly observe the inside of the vagina, including the condition of the cervix, vaginal wall and secretions, thereby facilitating the doctor to remove the lesions of the pathological changes in the vagina. During the operation of removing the lesions by laser, smoke and body fluids will be generated in the vagina, and physiological saline needs to be used to flush the lesions, so that there is a large amount of waste water and smoke in the vagina, which will affect the smooth progress of the operation of the doctor.
[0003] The prior art, such as the utility model patent with the publication number CN215383937U announced on January 4, 2022, discloses a surgical vaginal dilator with smoke and liquid discharge function, which comprises a dilating leaf, a lower dilating leaf and a push rod. An adjusting mechanism is arranged on the push rod for adjusting and positioning the upper dilating leaf during operation. A smoke discharge pipe is arranged along one side of the inner wall of the upper dilating leaf for discharging smoke. A drainage pipe is arranged along one side of the inner wall of the lower dilating leaf for discharging body fluids. The smoke and body fluids are discharged by the smoke discharge pipe and the drainage pipe, hoping to improve the convenience of the doctor's diagnosis and operation process.
[0004] However, in the utility model, only the drainage pipe arranged on the edge of the lower dilating leaf is used to suck out the body fluids and flushing liquids. The liquid in the vagina will flow outwards along the lower dilating leaf, and the drainage pipe can only suck out the liquid near the pipe opening. It does not have the effect of drainage and collection of liquid, and cannot quickly and completely discharge the liquid. A large amount of waste liquid generated during flushing is not discharged and will flow out of the dilator along the lower dilating leaf. These liquid containing bacteria not only block the doctor's view and affect the operation, but also directly pollute the operation environment and even affect the doctor's health. Therefore, a dilator with drainage channel is proposed to solve the above problems. SUMMARY
