Then the applicator is controlled to slowly enter the patient's body. At this time, the expansion plate 205 is controlled to expand outward, and the plate of the probe 102 slides on the separation plate 103. The probe 102 is also controlled by the contraction rod 105 to expand and open the vaginal wall. The first to enter is the visual detector 306, which will feed back the situation inside the uterus to the outside world, and can also detect the position of the probe 102 and the inner wall of the uterus, so that it is convenient to control the insertion depth of the applicator. When the applicator After arriving at the designated position, the medicine is applied according to the patient's needs. If the patient needs solid granular medicine, the power component 313 is started and the medicine is placed into the solid medicine delivery device 301 through the medicine delivery port 302. The power component 313 controls the auxiliary gear 314 to drive the power gear 315 to rotate. The power gear 315 controls the rotation of the control center column 304 to drive the transmission component 305 to rotate. At this time, the solid medicine will be driven by the transmission component 305 to move along the medicine delivery tube 303 until the solid medicine falls from the other end of the medicine delivery tube 303 into the uterus. Through the operation of the solid medicine delivery device 301, the solid medicine is transported to the uterus for application.

[0020] like Figure 7 As shown, the liquid medicine delivery device 307 is located at the rear end of the medicine application device, and the outer wall of the liquid medicine delivery device 307 is provided with a plurality of slots, and the outer wall of each slot is connected with a medicine dish 308, and different types of liquid medicines are stored in each medicine dish 308, and the outer wall of the medicine delivery tube 303 is provided with a plurality of delivery tubes 309, and different types of medicine dishes 308 correspond to the delivery tubes 309 of the medicines respectively; A connecting pipe 310 is clamped between the inside of each group of medicine dishes 308 and the outer wall of the delivery tube 309.

If the smearing method is used, the medicine application equipment will come into contact with the inner wall of the uterus, and the force of applying the medicine cannot be controlled, which can easily cause great harm to the patient. Through the operation of the medicine spray ring 311, not only the medicine is applied to the inside of the uterus, but also the risk factor of causing damage to the uterus is reduced.

[0021] like Figures 1 to 5 As shown, the expansion assembly 200 includes an expansion disk 201, which is located inside the housing 100. A plurality of expansion slots 202 and limiting slots 203 are provided outside the expansion disk 201, and the expansion slots 202 and the limiting slots 203 are connected to each other.

The outer wall of the expansion disk 201 is provided with a wind blade 206, and the outer wall array of the wind blade 206 is provided with a shifting blade 207, and the shifting blade 207 is in contact with the limiting pin 204; A support frame 208 is fixedly mounted on the inner wall of each expansion plate 205, and the other end of the support frame 208 is slidably connected to the outer wall of the delivery pipe 309. A connecting plate 209 is inserted between the outer walls of each expansion plate 205, and the outer wall of the connecting plate 209 is slidably connected to the inner wall of the expansion plate 205; During operation, after the medication device enters the patient's body, the expansion component 200 is required to expand the vagina and cervix, and the power piece 313 controls the wind blade piece 206 to rotate. When the wind blade piece 206 rotates, the toggle blade 207 will also rotate accordingly. When the outer wall of the toggle blade 207 contacts the limit pin 204, the limit pin 204 will be controlled by the toggle blade 207 to slide on the expansion disk 201. First, the limit pin 204 will slide on the expansion slide groove 202. At this time, the expansion plate 205 will be controlled to expand outward along the trajectory of the expansion slide groove 202. When the limit pin 204 slides to the limit slide groove 203, the limit pin 204 will control the expansion plate 205 to be in an expanded state.

[0022] Working principle: The shell 100 is an important component connecting the entire device. When the patient uses the medication device, the device will first be inserted into the body. When it reaches the appropriate depth, the expansion component 200 will be used to open the vaginal wall to fully expose the vagina and cervix. This not only facilitates observation of the situation inside the uterus but also makes it easier to apply medication. At this time, the medication can be applied to the inside of the uterus through the medication component 300 according to the internal situation. The medication application device has a solid medication channel and a liquid medication channel. When using the medication application device, the operator first holds the grip 101, and then applies an appropriate amount of lubricant on the probe 102. This can reduce the friction on the vaginal mucosa during insertion and reduce the patient's discomfort. Then the medication application device is controlled to slowly enter the patient's body. When the medication device enters the patient's body, the power piece 313 controls the air blade piece 206 to rotate. When the air blade piece 206 rotates, the toggle blade 207 will also rotate accordingly. When the outer wall of the toggle blade 207 contacts the limiting nail 204, the limiting nail 204 will be controlled by the toggle blade 207 to slide on the expansion disk 201. First, the limiting nail 204 will slide on the expansion slide groove 202. At this time, the expansion plate 205 will be controlled to expand outward along the trajectory of the expansion slide groove 202. When the limiting nail 204 slides to the limiting slide groove 203, the limiting nail 204 will control the expansion plate 205 to be in the expanded state. When the power piece 313 rotates in the opposite direction, the toggle blade 207 will reversely toggle the limiting nail 204 back along the original sliding trajectory. When the uterus reaches the initial position, the visual detector 306 enters first. The visual detector 306 will feed back the situation inside the uterus to the outside world. At the same time, it can also detect the position of the probe 102 and the inner wall of the uterus, so that it is convenient to control the insertion depth of the drug application device. When the drug application device reaches the specified position, the drug is applied according to the drug required by the patient. If the patient needs solid granular drugs, the power member 313 is started at this time, and the drug is placed into the solid drug delivery device 301 through the drug release port 302. The power member 313 controls the auxiliary gear 314 to drive the power gear 315 to rotate. The power gear 315 controls the rotation of the control center column 304 to drive the transmission member 305 to rotate. At this time, the solid drug will be driven by the transmission member 305 along the The drug delivery tube 303 moves until the solid drug falls from the other end of the drug delivery tube 303 into the uterus. If the patient needs liquid drugs, the liquid drug delivery device 307 is equipped with a drug dish 308 for storing different drugs. At this time, the connecting tube 310 sucks the drugs in the drug dish 308 into the delivery tube 309. After the drugs in the delivery tube 309 are transferred to the other end, the drugs will enter the drug spray ring 311. At this moment, the drug spray ring 311 rotates while spraying the internal drugs on the inner wall of the uterus through the spray port. The thickness of the inner wall of the uterus varies according to individual physique. If the smearing method is used, the drug application device will come into contact with the inner wall of the uterus, and the force of applying the drugs cannot be controlled, which can easily cause great harm to the patient.The operation of the liquid drug delivery device 307 not only plays the role of applying medicine to the inside of the uterus, but also reduces the risk of causing damage to the uterus. No matter what state of medicine the patient needs to apply, there is a corresponding structure for applying the medicine. The cooperation of the solid drug delivery device 301 and the liquid drug delivery device 307 can achieve the effect of simultaneously satisfying the application of two different forms of medicine.
