[0025] A device for treating intrauterine adhesions comprises two skeleton layers 1, which are symmetrically arranged to form a uterine-shaped ring, and the shape of the uterine-shaped ring is a bionic uterine structure; the material is selected from polypropylene (PP) material, the skeleton layer 1 comprises a first support member 11 and a second support member 12, the first support member 11 and the second support member 12 are hingedly arranged, and a longitudinal rod 2 is hinged at the top of the two skeleton layers 1; the device for treating intrauterine adhesions also comprises an outer sleeve 3, a connecting tube 31 is fixedly arranged at the bottom of the outer sleeve 3, the bottom ends of the two skeleton layers 1 are hinged to the connecting tube 31, and the outer sleeve 3 is slidably sleeved on the outside of the longitudinal rod 2; the bottom of the longitudinal rod 2 is opened, and the bottom of the longitudinal rod 2 is provided with an internal thread, and the longitudinal rod 2 is connected to a booster rod 4 through the internal thread.

[0026] like Figure 1 As shown, when the longitudinal rod 2 slides downward, the first support member 11 and the second support member 12 are hinged and thus contracted to form a contracted shape that is easier to enter the uterus, so as to reduce the patient's discomfort. After entering the uterine cavity, the longitudinal rod 2 is pushed to slide upward by the booster rod 4. At this time, the first support member 11 and the second support member 12 are unfolded into a supporting shape, which can completely support the uterine cavity and effectively prevent the recurrence of intrauterine adhesions.

[0027] At the same time, the interior of the longitudinal rod 2 is divided into a drug soaking part 21 and a drug spraying part 22. The drug soaking part 21 is used to fill and spray anesthetic drugs to relieve the patient's pain, and the drug spraying part 22 is used to spray therapeutic liquid to assist in treatment. The drug soaking part 21 is arranged above the drug spraying part 22, and the drug soaking part 21 and the drug spraying part 22 are separated by a first one-way valve 23; the drug soaking part 21 is adsorbed with tetracaine syrup, and tetracaine hydrochloride syrup (linin glue) is a commonly used local anesthetic with strong penetrating power and good diffusion. It can penetrate the mucosa and is clinically used for mucosal surface anesthesia for catheterization, cystoscopy, and gastroscopy; its analgesic effect is rapid, quick onset, and long duration; the longitudinal rod 2 is provided with a number of circular The outer sleeve 3 is provided with a drug delivery hole 32, and the inner wall of the outer sleeve 3 is provided with a connecting tube 33, one end of the connecting tube 33 corresponds to the drug delivery hole 32, and the other end of the connecting tube 33 matches the through hole; the diameter of the drug delivery hole 32 is 0.5mm~3mm, preferably 1mm~2mm, which is used to effectively release the drug; further, when the device is in the expanded state, the axes of the connecting tube 33, the drug delivery hole 32 and the through hole are on the same horizontal line, which can ensure the outflow of the drug solution. At the same time, the connecting tube 33 and the through hole may be slightly not on the same axis, but it does not affect the overall situation, and the connecting tube 33 can be made slightly larger than the through hole.

[0028] The drug soaking part 21 includes an inner porous hydrogel structure 24 and a cotton layer structure 25 wrapped in the outer layer of the porous hydrogel structure 24, so as to realize a multi-level slow drug release function.

[0029] A second one-way valve 26 is provided at the bottom of the longitudinal rod 2, above the internal thread; the first one-way valve 23 and the second one-way valve 26 are used to prevent the drug solution from flowing back out, and gas can be injected to achieve pressurization, thereby causing the internal drug body to reach the human body through the drug delivery hole 32, and slowly and long-term release, so as to achieve the effect of postoperative analgesia and treatment.

[0030] A plurality of T-shaped slots 27 are circumferentially arranged on the outer wall at the bottom of the longitudinal rod 2. The intrauterine adhesion therapeutic device also includes a hand-held rod 5, and the inner wall of the hand-held rod 5 is provided with a T-shaped protrusion 51 that fits the T-shaped slot 27; a limit stop ring 41 is fixedly arranged on the side wall of the booster rod 4, and the top of the limit stop ring 41 abuts against the bottom of the hand-held rod 5; specifically, during use, the hand-held rod 5 is connected by inserting the T-shaped protrusion 51 through the T-shaped slot 27 at the bottom of the longitudinal rod 2, and then the booster rod 4 is threadedly connected, and then pushed into the uterine cavity, and after the injection of the drug is completed, by holding the hand-held rod 5, The booster rod 4 can be rotated to separate the booster rod 4 from the longitudinal rod 2, so as to avoid the tingling sensation caused by stimulating the patient's uterine cavity by only rotating the booster rod 4; and after the booster rod 4 is disassembled, the hand-held rod 5 loses the limit of the bottom limit baffle ring 41 and can be slid out, so that the rest of the device can be left in the patient's body for continuous treatment; at the same time, a pull rope 28 is provided on the top and bottom of the longitudinal rod 2, and the pull rope 28 is a nylon line; when the device needs to be dragged out at the end, the treatment device remaining in the patient's body can be pulled out by pulling the pull rope 28.

One end of the pressure injector and the drug delivery device are both detachably connected to a connecting catheter, and the connecting catheter is connected to the interior of the longitudinal rod 2 through a second one-way valve 26 .

[0032] When in use, the medicine is injected from the second one-way valve 26 through the pressure syringe and the injection needle of the drug delivery device and pressurized at the same time, so that the medicine is sprayed out from the drug delivery hole 32 and reaches the human body, and is slowly and long-actingly released to achieve the effect of postoperative analgesia.

[0033] The uterine ring is covered with an outer layer membrane, which is made of a mixture of silica gel and nano-paper containing chitosan, and is provided with a number of release holes; medical chitosan can further enhance the anti-adhesion effect of the device, and at the same time, the outer layer membrane can be further expanded by bulging under the internal air pressure to avoid adhesion in the uterine cavity.

[0034] The first one-way valve 23 and the second one-way valve 26 are built-in spring-loaded plug valves.

[0035] The working principle of the above-mentioned intrauterine adhesion treatment device is as follows:

[0036] First, if Figure 1 As shown, the whole device is in a contracted state, and then the device is pushed into the uterine cavity and the booster rod 4 is pushed to make the device in a contracted state. Figure 2 The expanded state shown in the figure is then pushed inward by an external pressure syringe and a drug delivery device to push the liquid medicine and input air pressure, so that the liquid medicine and tetracaine hydrochloride slurry are pushed out through the through hole, thereby achieving the purpose of treatment and analgesia.
