Description

Intrauterine drug slow-release device for treating adenomyosis

Technical Field

The utility model relates to the technical field of gynecological medical appliances, in particular to an intrauterine drug slow-release device for treating adenomyosis.

Background

Adenomyosis is the invasion of the endometrium and glands of the uterus into the myometrium of the uterus. Under normal conditions, the endometrium is below the muscle layer and is separated by a limit, when the endometrium and the superficial muscle layer are damaged, such as delivery, multiple artificial abortion, uterine curettage and the like, the endometrium can run by mistake, and the endometrium grows and develops in the muscle layer of the uterus and stimulates the proliferation of the surrounding muscle cells, so that the adenomyosis is formed. The endometrium in the muscular layer can be the same as the normal endometrium, and can generate periodic congestion, edema and even bleeding along with the change of menstrual cycle, so that the strong uterine contraction can cause severe lower abdominal pain, and simultaneously, the uniformity of the uterus of a patient is increased, the uterus is hard, the menstruation is excessive, and the anemia can be seriously generated in the patient.

The treatment methods for the disease mainly comprise the following steps: 1. the uterus is removed by operation; 2. conservative operation treatment, and 3, traditional Chinese medicine conditioning treatment. The three treatment methods have advantages and disadvantages. Historically, adenomyosis occurred in most women who are older than 40 years of age but has become a trend toward younger women in recent years, which may be related to the increase of surgeries such as cesarean section and artificial abortion. Because patients are gradually younger and are not accepted by patients and families by traditional methods such as surgical excision, the patients are mostly treated for a long time by placing Menyle's ring (levonorgestrel intrauterine sustained release system) in the uterus. The Manyule ring is also called Manyule contraceptive device, is the only local drug contraceptive ring in the prior art, has a very small progesterone slow-release device, ensures that the Manyule ring is placed in the uterine cavity for 5 to 6 years, continuously and constantly releases a small amount of progesterone to the local part of the uterus, can cause the temporary atrophy of endometrium, inhibit the growth of endometrium after being used, effectively controls the menstrual flow, shortens the menstrual bleeding time, relieves the dysmenorrhea, and ensures that the internal environment of cervix, uterine cavity and endometrium are in the state of not suitable for conception, thereby obtaining the extremely reliable contraceptive effect.

Chinese patent No. CN204050646U discloses an intrauterine drug release device for treating adenomyosis, comprising a longitudinal tube with a drug inside and a fixing bracket arranged on the upper part of the longitudinal tube, wherein a tail fiber for taking out is arranged at the tail part of the longitudinal tube, the fixing bracket comprises a fixing support rod extending upwards from the upper end of the longitudinal tube, a fixing knot is arranged at the upper end part close to the fixing support rod, and a plurality of elastic branch rods are arranged on the fixing support rod; and at least two auxiliary elastic supporting rods are arranged on the tail fibers at the lower part of the longitudinal pipe.

The above prior art solutions have the following drawbacks: although the medicine slow-release device is fixed at the cervical orifice through the elastic branch supporting rod and the auxiliary elastic supporting rod up and down, so that the medicine slow-release device cannot be washed out of the cervix, and the treatment effect is ensured, in the actual use process, when the medicine slow-release device is placed in the uterus, the protective tube needs to be drawn out outwards, and at the moment, the inner wall of the protective tube can rub against the sucker, so that the use of the sucker is influenced.
