The invention discloses a cervical dilation rod capable of controlling medicine release, and relates to the technical field of medical instruments, the cervical dilation rod comprises an insertion piece, one end of the insertion piece is fixedly connected with a connecting thread sleeve, one end of the connecting thread sleeve is fixedly connected with a limiting plate, and the interior of the connecting thread sleeve is in threaded connection with a driving rod; a plurality of flexible arc-shaped petals are installed at the end, away from the connecting thread sleeve, of the inserting piece, a liquid supplementing piece is fixedly connected to one side of the interior of the inserting piece, one end of the liquid supplementing piece communicates with the flexible arc-shaped petals, the driving rod is manually rotated, so that components in the driving rod operate, one end of the driving rod extrudes the flexible arc-shaped petals from inside to outside, and the flexible arc-shaped petals are fixed to the end, away from the connecting thread sleeve, of the inserting piece. The extrusion speed is stable, the multiple flexible arc-shaped flaps are expanded to achieve radial expansion, a doctor can control the expansion diameter in real time according to the hand feeling, follow-up operation treatment of the doctor is facilitated, the doctor becomes a main guide of the expansion process through pure mechanical transmission, accurate control can be conducted according to the real-time hand feeling, and the operation safety is remarkably improved.

The utility model relates to a rotatable cervical dilation rod, which belongs to the technical field of medical instruments and comprises a front end portion and a deformation portion, the front end portion is guided to penetrate into the cervix, and the deformation portion is arranged at one end of the front end portion and used for dilating the cervix. The deformation part comprises an air cylinder fixedly connected to one end of the front end part, an air bag fixedly connected to the outer portion of the air cylinder in a sleeving mode, an injection opening formed in the end, close to the front end part, of the air cylinder, and a piston assembly arranged in the air cylinder and used for injecting air in the air cylinder into the air bag from the injection opening. The size of the air bag can be adjusted to achieve gradual expansion of the cervix uteri, compared with a traditional mode that metal cervix uteri rods of different sizes repeatedly enter and exit the uterine cavity one by one for expansion, efficiency is high, the operation process is greatly simplified, and operation cost is reduced. Therefore, infection caused by repeatedly entering and exiting the uterine cavity can be reduced, and the probability of cervical injury and uterine perforation is reduced.
