Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable micro-angiography device for clamping the uterus and fallopian tube. Background Art

[0002] Hysterosalpingography involves injecting a contrast agent into the uterine cavity and fallopian tubes, and then observing and recording the flow of the contrast agent through X-ray transmission and radiography to display the morphology of the uterine and fallopian tube cavities, assess the shape, size, and presence of deformities of the uterus and fallopian tubes, and determine the condition of the patient's uterus and fallopian tubes. Currently, a single-balloon tube is commonly used for hysterosalpingography. The tip of the tube is inserted into the cervix, and the inflatable balloon blocks the internal cervical os to prevent the backflow of the contrast fluid subsequently introduced into the uterus. In this method, the tube is poorly fixed in the cervical canal cavity and is prone to slippage, causing discomfort to the patient, and easily causing damage to the patient's uterus and fallopian tubes, increasing the patient's pain. It is also prone to leakage of contrast fluid, affecting the accuracy of the radiographic examination.

[0003] In the existing technology, an airbag that matches the shape of the lower end of the uterine cavity and the external cervical os is used to improve the stability of the angiography tube inside the cervical canal. In this method, it is impossible to adapt to patients with different sizes of the internal cervical os, and continuously inflating the smaller airbag to make it expand and enlarge it may cause it to break, reducing the patient's comfort; an inflatable conical sealing airbag is used to seal the internal cervical os to prevent the contrast fluid from overflowing during angiography. In this method, there is a lack of space occupied inside the patient's uterus, which increases the amount of contrast fluid used and the cost of the angiography examination. In addition, it is impossible to lubricate the internal cervical os while sealing it, reducing the patient's comfort. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing technology that it cannot adapt to patients with different sizes of cervical os, and that continuously inflating a smaller airbag to make it expand and enlarge it may cause it to break, thereby reducing the patient's comfort. An adjustable uterine and fallopian tube clamping micro-angiography device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The device for micro-angiography with adjustable clamping of the uterus and fallopian tube comprises a tapered angiography tube, wherein the end of the angiography tube with a smaller diameter is connected to a liquid outlet tube, and further comprises: An operating component, wherein a working end of the operating component extends into the interior of the angiography tube; An adjustment mechanism includes a plurality of conical airbags wrapped around the outside of the angiography tube, wherein two adjacent conical airbags are connected to each other and fixedly connected to the same connecting ring on the inner side, and the connecting ring is loosely fitted with the outside of the angiography tube. The plurality of conical airbags form a complete airbag, and both ends of the complete airbag are sealed and fixedly connected to the outside of the angiography tube with an outer sealing ring, and form a sealed space with the outside of the angiography tube. The adjustment mechanism also includes an inflation tube, one end of which extends into the interior of the angiography tube, seals through the tube wall of the angiography tube, and is connected to the sealed space near the liquid outlet tube.

[0006] Preferably, the operating assembly includes a metal guide wire, one end of which is equipped with a manipulation head and the other end of which extends into the interior of the angiography tube.

[0007] Preferably, the angiography tube includes a sliding tube and a liquid catheter that are interconnected, the liquid outlet tube is connected to the end of the liquid catheter away from the sliding tube, the end of the metal guide wire away from the manipulation head and the inflation tube are both extended into the interior of the sliding tube and the liquid catheter, a through hole is opened on the liquid catheter for the inflation tube to pass through the seal, and the two outer sealing rings are both gap-connected to the outside of the liquid catheter.

[0008] Preferably, the sliding tube is connected to an external support assembly, which includes a rubber ring that is slidably sleeved on the outside of the sliding tube. A plurality of support plates are fixedly connected to the side of the rubber ring away from the catheter tube. The plurality of support plates are trumpet-shaped, and the end with a larger diameter is away from the rubber ring.

[0009] Preferably, an inflation valve is installed on the inflation tube, and the end away from the liquid guide tube is connected to an external air source.

[0010] Preferably, one end of the sliding tube away from the liquid guiding tube is connected to a liquid adding tube, and one end of the liquid adding tube away from the sliding tube is connected to an external contrast fluid source.

[0011] Preferably, it further comprises a lubrication component, which comprises a subcutaneous cavity provided in the wall of the conical airbag, wherein a plurality of liquid inlet holes are connected between the subcutaneous cavity and the outside, and the liquid inlet holes are provided on the conical airbag.

[0012] Preferably, there are three conical airbags, which are respectively a small airbag, a medium airbag and a large airbag. The small airbag, the medium airbag and the large airbag are connected in sequence. The two outer sealing rings are fixedly connected to the small airbag and the large airbag at one end away from the medium airbag, and the two connecting rings are respectively a first inner sealing ring and a second inner sealing ring. The small airbag and the medium airbag are both fixedly connected to the second inner sealing ring, and the medium airbag and the large airbag are both fixedly connected to the first inner sealing ring. The inflation tube passes through one end of the catheter and is connected to the partial sealed space at the small airbag.

Before the contrast fluid is introduced into the patient's uterus, the air bags are inflated to block the internal cervical os and effectively prevent the contrast fluid from flowing back. The air bags of different sizes can be conveniently adapted to patients with different sizes of internal cervical os, thereby improving the adaptability of the device for angiography examination. At the same time, when the air bags are extended into the patient's uterus and inflated, the inflated air bags will occupy part of the space inside the patient's uterus, thereby reducing the amount of contrast fluid filling the uterus, improving the efficiency of the angiography examination, and reducing the cost of the angiography examination. A subcutaneous cavity is opened in the wall of the multiple air bags, and lubricating fluid is stored in the subcutaneous cavity. When the air bags are inflated, the subcutaneous cavity is squeezed to facilitate the lubricating fluid to flow out through the liquid inlet, lubricating the environment inside the uterus, alleviating the patient's discomfort, and improving the patient's comfort.

[0016] 2. The present invention sets a first inner sealing ring and a second inner sealing ring, and utilizes the patient's cervical os to squeeze the gap between adjacent airbags, so that the sealing ring is in sealing contact with the angiography tube, and the adjacent airbags are sealed and separated. When inflating, the airbags located inside the uterus are inflated independently, and the inflation operation of different airbags is completed through a single inflation tube. There is no need to set up multiple inflation tubes, and the inflation tubes can be conveniently integrated into the interior of the angiography tube; at the same time, when the patient's cervix and vagina squeeze the airbag, the lubricating fluid in the subcutaneous cavity flows out to lubricate the cervix and vagina, thereby improving the patient's comfort and avoiding secondary damage to the patient's internal body environment.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 4 The adjustable uterine fallopian tube micro-angiography device comprises a tapered angiography tube, an end of the angiography tube having a smaller diameter is connected to a liquid outlet tube 15, and further comprises: The operating component has a working end extending into the interior of the angiography tube.

[0027] The adjustment mechanism includes a plurality of conical airbags covered on the outside of the angiography tube. Two adjacent conical airbags are connected to each other and fixedly connected to the same connecting ring on the inner side. The connecting ring is gap-matched with the outer side of the angiography tube. The plurality of conical airbags form a complete airbag. Both ends of the complete airbag are sealed and fixedly connected to the outside of the angiography tube with an outer sealing ring 10, and form a sealed space with the outside of the angiography tube. The adjustment mechanism also includes an inflation tube 5. One end of the inflation tube 5 extends into the interior of the angiography tube, seals through the tube wall of the angiography tube, and is connected to the sealed space near the liquid outlet tube 15.

[0028] Reference Figure 2 and Figure 5 The operating component includes a metal guide wire 2, one end of which is equipped with a control head 1 and the other end extends into the interior of the angiography tube.

[0029] By manipulating the metal guide wire 2 through the manipulation head 1, the sliding tube 6 and the liquid catheter 9 can be pushed deep into the patient's vagina, so that the liquid outlet tube 15 extends into the patient's uterus, facilitating the subsequent introduction of contrast fluid.

[0030] The angiography tube includes a sliding tube 6 and a liquid catheter 9 that are interconnected. The liquid outlet tube 15 is connected to the end of the liquid catheter 9 away from the sliding tube 6. The end of the metal guide wire 2 away from the control head 1 and the inflation tube 5 are both extended into the interior of the sliding tube 6 and the liquid catheter 9. A through hole is opened on the liquid catheter 9 for the inflation tube 5 to pass through in a sealed manner. Two outer sealing rings 10 are both gap-connected to the outside of the liquid catheter 9.

[0031] An external support assembly is connected to the sliding tube 6, and the external support assembly includes a rubber ring 7 that is slidably sleeved on the outside of the sliding tube 6. A plurality of support plates 8 are fixedly connected to the side of the rubber ring 7 away from the catheter 9. The plurality of support plates 8 are trumpet-shaped, and the end with a larger diameter is away from the rubber ring 7.

[0032] When pushing the catheter 9 into the patient's vagina, the position of the rubber ring 7 is adjusted so that the multiple support plates 8 can open the patient's vagina, making it convenient for the doctor to remove the dilator. There is no need to operate the dilator while performing angiography, which reduces the doctor's operating burden.

[0033] An inflation valve 4 is installed on the inflation tube 5, and one end away from the liquid guiding tube 9 is connected to an external air source.

[0034] The external air source is used to supply air. When the inflation valve 4 is opened, the external air source inflates the conical airbag through the inflation tube 5. After the conical airbag is inflated, it can block the patient's external cervical os, effectively avoiding the backflow of contrast fluid and improving the stability of the contrast examination.

[0035] One end of the sliding tube 6 away from the liquid guiding tube 9 is connected to the liquid adding tube 3 , and one end of the liquid adding tube 3 away from the sliding tube 6 is connected to an external contrast liquid source.

[0036] The external contrast fluid source is used to provide contrast fluid, which is passed into the interior of the sliding tube 6 and the liquid guide tube 9 through the liquid adding tube 3, and into the patient's uterus through the liquid outlet tube 15, and then into the fallopian tube through the uterus, so as to facilitate contrast examination of the fallopian tube.

[0037] Reference Figure 3-Figure 7 , also includes a lubrication component, the lubrication component includes a subcutaneous cavity 18 opened in the wall of the conical airbag, the subcutaneous cavity 18 is connected to the outside world by multiple liquid inlet holes 14, and the liquid inlet holes 14 are opened on the conical airbag.

[0038] When the conical airbag is inflated or squeezed by the patient's vaginal wall and cervix, the lubricating fluid inside the subcutaneous cavity 18 is squeezed out, thereby lubricating the patient's vaginal wall and cervix and alleviating the patient's discomfort.

[0039] There are three conical airbags, which are respectively a small airbag 11, a medium airbag 12 and a large airbag 13. The small airbag 11, the medium airbag 12 and the large airbag 13 are connected in sequence. The two outer sealing rings 10 are fixedly connected to the small airbag 11 and the large airbag 13 at one end away from the medium airbag 12. The two connecting rings are respectively a first inner sealing ring 16 and a second inner sealing ring 17. The small airbag 11 and the medium airbag 12 are both fixedly connected to the second inner sealing ring 17, and the medium airbag 12 and the large airbag 13 are both fixedly connected to the first inner sealing ring 16. The inflation tube 5 passes through one end of the catheter 9 and is connected to the partial sealed space at the small airbag 11.

[0040] The complete airbag consisting of the small airbag 11 , the middle airbag 12 and the large airbag 13 is conical, and the end with a smaller diameter is close to the liquid outlet pipe 15 .

[0041] By sequentially enlarging the small airbag 11, the medium airbag 12 and the large airbag 13, the cervical os of different sizes can be adapted, thereby improving the adaptability of radiographic examination.

[0042] The outer surfaces of the sliding tube 6 and the support plate 8 are all provided with a microporous coating, and the outer surfaces of the small airbag 11, the medium airbag 12 and the large airbag 13 are all provided with a sponge coating.

[0043] When in use, the device can be immersed in lubricating liquid, and the lubricating liquid is infiltrated through the microporous coating and the sponge coating. When the device is then inserted into the patient's vagina, lubrication is performed to reduce the patient's discomfort.

[0044] When the present invention is used, the small airbag 11, the medium airbag 12 and the large airbag 13 are first immersed in the lubricating liquid, and the lubricating liquid is allowed to enter the interior of the subcutaneous cavity 18 through the liquid inlet hole 14. At the same time, the surface of the airbag is lubricated, and the surface of the support plate 8 and the sliding tube 6 is also coated with lubricating liquid.

[0045] Liquid is introduced into the sliding tube 6 and the liquid guiding tube 9 through the liquid adding tube 3 to test whether the liquid outlet tube 15 can discharge liquid normally, and corresponding debugging is performed to ensure normal liquid discharge.

[0046] In the normal operation process, the doctor first uses a dilator to open the patient's vagina and inserts the angiography tube. Using the dilator all the time will cause discomfort to the patient, and it is very inconvenient to use the dilator with one hand and use the other hand to control the entry and exit of the angiography tube.

[0047] This device uses a control head 1 and a metal guide wire 2 in the middle to allow the angiography tube to pass through the vagina. When it contacts the internal cervical opening, the speculum can be taken out. By adjusting the position of the rubber ring 7 on the sliding tube 6, the support plate 8 is moved to the vaginal opening. When the speculum is taken out, the vaginal opening will naturally fall on the support plate 8, and the support plate 8 will appropriately expand the vaginal opening, making it convenient for the doctor to perform subsequent angiography operations, reducing the patient's discomfort, improving the patient's comfort, and allowing the patient to cooperate more with the treatment.

[0048] The metal guide wire 2 is used to allow the angiography tube to drive the small airbag 11 into the internal os of the cervix. Since each patient's age, reproductive history, and physical condition are different, the size of the internal os of the cervix varies significantly, which makes it difficult for a single airbag to meet the needs of blocking the internal os of the cervix. If an airbag that is too small is continuously inflated to make it expand and become larger, it may break, and an airbag of inappropriate size may cause the patient's discomfort to worsen.

[0049] During actual operation, a small air balloon 11, a medium air balloon 12 or a large air balloon 13 is selected to be inserted according to the actual size of the patient's internal cervical os.

[0050] When the patient's internal cervical os is small, the operating catheter 9 carries the small air bag 11 into the interior of the uterus. The internal cervical os is clamped between the small air bag 11 and the middle air bag 12. The lubricating fluid inside the subcutaneous cavity 18 of the middle air bag 12 is squeezed out to lubricate the internal cervical os, thereby improving the patient's comfort.

[0051] At the same time, the patient's cervical os squeezes the second inner sealing ring 17, so that the second inner sealing ring 17 is firmly attached to the outer wall of the catheter 9, sealing and separating the small air bag 11 and the middle air bag 12. At this time, the inflation valve 4 is opened, and the small air bag 11 is inflated through the inflation tube 5. The small air bag 11 is inflated and bulges, blocking the internal cervical os, effectively preventing the contrast fluid used in subsequent angiography examinations from flowing back; at the same time, the small air bag 11 bulges and squeezes the subcutaneous cavity 18 above it, so that the lubricating fluid inside the subcutaneous cavity 18 flows out through the liquid inlet hole 14, continuing to lubricate the environment inside the uterus, and improving the patient's comfort.

[0052] Then, contrast fluid is introduced into the uterus through the liquid adding tube 3, the sliding tube 6, the liquid guiding tube 9 and the liquid outlet tube 15. The contrast fluid gradually enters the fallopian tube through the uterus, making it convenient to perform contrast detection on the fallopian tube and judge the condition.

[0053] When the patient's cervical os is of medium size, the operating catheter 9 carries the small airbag 11 and the medium airbag 12 into the interior of the uterus. The patient's cervical os is clamped between the medium airbag 12 and the large airbag 13. The large airbag 13 and the first inner sealing ring 16 are squeezed, and the lubricating fluid inside the subepithelial cavity 18 of the large airbag 13 is squeezed out for lubrication. After the first inner sealing ring 16 is squeezed, it seals and separates the medium airbag 12 and the large airbag 13.

[0054] At this time, the inflation operation is performed. Since the second inner sealing ring 17 is suspended inside the uterus, there is a gap between the second inner sealing ring 17 and the catheter 9, so that the small airbag 11 and the middle airbag 12 are inflated at the same time. After the middle airbag 12 is inflated, it blocks the internal cervical os, effectively preventing the contrast fluid from flowing back. After the small airbag 11 is inflated, it occupies part of the space inside the uterus, which makes it convenient to reduce the contrast fluid filling the inside of the uterus and reduce the use of contrast fluid.

[0055] When the small airbag 11 and the middle airbag 12 are inflated, they will also squeeze the subcutaneous cavity 18 thereon, so that the lubricating fluid continues to lubricate the environment in the uterus, thereby improving the patient's comfort.

[0056] Then the contrast fluid is injected to complete the radiographic examination of the patient's fallopian tubes.

[0057] When the patient's internal cervical os is relatively large, the catheter 9 is operated to move the small airbag 11, the medium airbag 12 and the large airbag 13 into the patient's uterus, and the same operation of inflation and contrast fluid introduction is performed to complete the radiographic examination.

[0058] After the angiography is completed, the gas is released and the device is removed. Since the lubricating fluid retained in the subcutaneous cavity 18 has been lubricating the internal environment of the uterus, cervix and vagina, it greatly improves the patient's comfort and avoids secondary damage to the internal environment of the patient's body.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
