Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a uterine cavity compression hemostat for obstetrics and gynecology. Background Art

[0002] The uterine cavity compression hemostat usually adopts the principle of balloon compression. After being inserted into the uterine cavity, the balloon is expanded by inflating or filling with water, so as to mechanically compress the uterine cavity and achieve the purpose of hemostasis. This method is often used in the treatment of postpartum hemorrhage, and has the advantages of small trauma, simple operation, safety and high economic benefits.

[0003] In related technologies, such as a uterine cavity compression balloon with the publication number of CN215018261U, through the improvement of the uterine cavity water balloon structure, auxiliary balloon bodies are uniformly arranged on the periphery of the main balloon body. This solution can uniformly apply pressure according to the characteristics of the uterine inner wall by compressing and expanding the balloon, but the positions of the compression balloon and the expanded balloon are fixed, and there is a certain degree of fixity during compression hemostasis, lacking flexibility.

[0004] Another example is a multifunctional uterine cavity compression balloon with the publication number of CN221830701U, which includes a drainage tube body and a uterine cavity compression balloon. The uterine cavity compression balloon is arranged on the outer peripheral side wall above the drainage tube body, and a vaginal balloon is arranged on the outer peripheral side wall of the drainage tube body below the uterine cavity compression balloon. This solution can prevent the uterine cavity compression balloon from falling off by blocking the patient's vagina with the vaginal compression balloon, and can promote the reduction of bleeding in the endometrium by administering hemostatic drugs into the uterine cavity through the drug administration cavity. However, the pressure applied by the uterine cavity compression balloon will hinder the coverage and circulation of the hemostatic drugs, and the hemostatic range is relatively small.

[0005] When injecting liquid or gas into the existing compression balloon, it expands synchronously as a whole. Therefore, the compression force at each position is the same. If the compression force at a certain position is insufficient, it is necessary to synchronously increase the overall compression force, resulting in a relatively large overall compression feeling on the patient's uterus. Summary of the Invention

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0020] As Figures 1 - 13 shown, the embodiments of the present invention provide a gynecological and obstetric intrauterine compression hemostat, including: A main pipeline 1, a main branch pipe 101 is fixedly connected to the lower part of the main pipeline 1, and a main bottom pipe 102 is fixedly connected to the bottom of the main pipeline 1; Refer to Figure 1, the main body pipe 1 is used to be inserted into the uterus as a whole through the vagina. The main body branch pipe 101 is used to inject liquid or gas into the main body pipe 1, and a control valve is provided thereon to control the opening or closing of the main body branch pipe 101. The main body bottom pipe 102 is used to provide support for the drainage lower pipe 9 to ensure the stable force of the drainage lower pipe 9.

[0021] The intrauterine cyst 3 is fixedly installed at the top of the main body pipe 1. An oval opening is provided at the top of the intrauterine cyst 3, and a drainage upper pipe 301 is fixedly connected to the oval opening. An inclined dividing wire 3011 is fixedly connected inside the drainage upper pipe 301; Reference Figure 2 , Figure 3 , the intrauterine cyst 3 is made of a transparent material. In the inflated state, it is convenient to observe the bleeding condition of the uterine inner wall. The intrauterine cyst 3 is used to expand under the action of injecting liquid or gas to initially compress the uterine inner wall, so that the liquid in the uterus is pushed out and then discharged from the oval opening. The dividing wire 3011 is used to divide blood clots to make blood and blood clots easier to discharge.

[0022] The intrauterine cyst 3 includes an inner elastic layer 306. A pressing part 307 is provided on the inner elastic layer 306. An outer elastic layer 302 is fixedly connected to the outside of the inner elastic layer 306. A containing cavity 303 is provided inside the outer elastic layer 302. A liquid hemostatic drug is filled in the containing cavity 303. An arc-shaped opening is provided at the lower part of the containing cavity 303. A releasing part 305 is provided at the arc-shaped opening. A pressing part 304 is provided on one side of the containing cavity 303 close to the releasing part 305. The releasing part 305 and the pressing part 304 are in elastic and close contact; Reference Figure 13 , the inner elastic layer 306 and the outer elastic layer 302 can expand synchronously under the pressure of injecting liquid or gas. In the contracted state, the volume of the containing cavity 303 is small, and the internal liquid hemostatic drug can completely fill the containing cavity 303. The releasing part 305 and the pressing part 304 will be in close contact, so that the liquid hemostatic drug will not flow out of the containing cavity 303; in the inflated state, the volume of the containing cavity 303 becomes larger, and the internal liquid hemostatic drug does not completely fill the containing cavity 303. At this time, due to the deformation acting force provided by the arc-shaped cyst 501, the pressing part 307 synchronously generates a deformation thrust, so that the containing cavity 303 is pressed, and the liquid hemostatic drug sprays out from the gap between the releasing part 305 and the pressing part 304. Due to the blockage of the uterine inner wall, part of this liquid medicine directly falls on the uterine inner wall, and part of it will flow to the outer surface of the outer elastic layer 302, which can directly act on the bleeding part to play a role in drug hemostasis.

[0023] A drug groove 308 is provided between adjacent containing cavities 303. The drug groove 308 is distributed along the meridian direction and is continuously arranged; Reference Figure 10, the drug trough 308 is arranged in the warp direction. The liquid hemostatic drug flowing into the outer surface of the outer elastic layer 302 can flow into the drug trough 308. Through the drug trough 308, the liquid hemostatic drugs at different positions can be evenly dispersed, maximizing the utilization of the liquid hemostatic drug. The continuous design enables the liquid hemostatic drug to flow to the entire drug trough 308, featuring a long flow path and a wide acting surface of the liquid hemostatic drug.

[0024] The holding force member 7 is fixedly arranged in the main body pipe 1 to ensure the connection of the main body pipe 1; the holding force member 7 includes a holding pipe 701, a protective ring 702 is fixedly connected to the holding pipe 701, an air flow channel 703 is arranged on the protective ring 702, and an accommodation channel 704 is arranged in the holding pipe 701; Reference Figure 2 、 Figure 6 , preferably, there are two upper and lower protective rings 702. While providing a supporting force in the main body pipe 1, it also provides space for the rotation of the drainage lower pipe 9. The air flow channel 703 can be of any shape as long as it can ensure the flow of liquid or gas. The accommodation channel 704 is used to accommodate the drainage lower pipe 9, and the drainage lower pipe 9 can rotate in the accommodation channel 704.

[0025] The drainage lower pipe 9 is coaxially arranged inside the main body pipe 1. The bottom of the drainage lower pipe 9 is fixedly connected with an operation ring 901. The top of the drainage lower pipe 9 is rotatably connected with the drainage upper pipe 301, and the operation ring 901 is rotationally matched with the main body bottom pipe 102; Reference Figure 2 , on the one hand, the drainage lower pipe 9 is used for draining and discharging intrauterine fluid. On the other hand, by controlling the rotation of the drainage lower pipe 9 and the balloon body 4, the targeted component 5, and the micro electronic camera 6 on the drainage lower pipe 9 through the operation ring 901, it can meet the needs of observing the bleeding site in all directions and targeted compression hemostasis.

[0026] The upper part of the drainage lower pipe 9 passes through the holding force member 7, and the lower part of the drainage lower pipe 9 passes through the main body bottom pipe 102. An indication part 902 is arranged on the operation ring 901, and the indication part 902 is consistent with the orientation of the micro electronic camera 6; Reference Figure 2 、 Figure 4 , the operation ring 901 is used to operate the rotation of the drainage lower pipe 9, and the indication part 902 is used to indicate the shooting direction of the micro electronic camera 6, facilitating the determination of the bleeding site and reducing the operation discrimination difficulty.

[0027] The balloon body 4 is arranged inside the intrauterine balloon 3. A balloon pipe 401 is fixedly connected to the balloon body 4, and the balloon pipe 401 is led out from the lower end of the drainage lower pipe 9; Reference Figure 2, the balloon body 4 expands under the action of injected liquid or gas. The balloon body 4 provides fixed-point pressure on the part of the uterine cavity of the intrauterine cyst 3 close to the fallopian tube, enabling the intrauterine cyst 3 to compress the part of the uterine cavity close to the fallopian tube, avoiding positions where pressure cannot be applied. The balloon body 4 can be any one of a sphere, an ellipsoid, and a long cylinder, and can be produced according to actual needs; the balloon pipeline 401 is used for injecting liquid or gas, and a control valve is provided thereon to control the opening and closing of the balloon pipeline 401. And for the visualization of pressure, a hydraulic gauge or a pneumatic gauge can be set.

[0028] The targeted component 5 is arranged inside the intrauterine cyst 3. The targeted component 5 includes an integrally formed arc-shaped cyst 501 and a branched cyst 502. The arc-shaped cyst 501 is arc-shaped, and an arc-shaped cyst pipeline 503 is fixedly connected to the arc-shaped cyst 501. The arc-shaped cyst pipeline 503 extends from the lower end of the drainage lower tube 9; Reference Figure 8 , Figure 2 , the arc-shaped cyst pipeline 503 is used for injecting liquid or gas, and a control valve is provided thereon to control the opening and closing of the arc-shaped cyst pipeline 503. For the visualization of pressure, a hydraulic gauge or a pneumatic gauge can be set; the arc-shaped cyst 501 and the branched cyst 502 expand under the action of liquid or gas, and can perform secondary targeted pressure on the intrauterine cyst 3 from the inside to the outside, avoiding synchronous compression of other parts and causing discomfort to the patient. The expanded branched cyst 502 can be in contact with the upper support surface 1001 of the upper force-bearing body 10 to provide a support force for the arc-shaped cyst 501 and improve the support effect.

[0029] The arc-shaped cyst 501 includes an inner arc part 5011 and an outer arc part 5012. The deformation and expansion amount of the outer arc part 5012 is greater than that of the inner arc part 5011; Reference Figure 8 , due to the difference in deformation and expansion amount between the outer arc part 5012 and the inner arc part 5011, therefore, under the action of the same hydraulic pressure or pneumatic pressure, the deformation and expansion amount of the outer arc part 5012 is large, and the deformation and expansion amount of the inner arc part 5011 is small, which can provide a greater radial compression force to achieve a good compression effect.

[0030] The micro electronic camera 6 is fixedly installed at the corresponding side wall of the center of the intrauterine cyst 3 of the drainage lower tube 9. The micro electronic camera 6 is on the same side as the balloon body 4 and on the opposite side of the arc-shaped cyst 501. The micro electronic camera 6 can observe the bleeding point from the inside to the outside; Reference Figure 2, the microelectronic camera 6 is an existing product, which is a wireless camera and transmits signals via Bluetooth. It can transmit the captured images to an external display, enabling direct observation of the bleeding sites remaining on the uterine inner wall after the initial compression by the uterine cyst 3, providing accurate guidance for subsequent targeted compression hemostasis.

[0031] It further includes a vaginal cyst 2, which is fixedly arranged at the outer wall of the main body duct 1 corresponding to the vagina. A vaginal cyst duct 201 is fixedly connected to the lower part of the vaginal cyst 2. The vaginal cyst 2 includes a disc-shaped part 202 and an enclosing part 203. The enclosing part 203 is located above the disc-shaped part 202, and the longitudinal cross-sectional shape of the enclosing part 203 is U-shaped. Reference Figure 2 , Figure 13 , the vaginal cyst duct 201 is used for injecting liquid or gas, and a control valve is provided thereon to control the opening and closing of the vaginal cyst duct 201. For pressure visualization, a hydraulic gauge or a pneumatic gauge can be provided. The disc-shaped part 202 is used to fit the vaginal inner wall, providing support for the whole to avoid the whole falling off and improving the hemostasis stability. While the enclosing part 203 is in contact with the vaginal inner wall, its upper part can surround the uterine orifice, exerting pressure on the uterine orifice from the outside to the inside, cooperating with the uterine cyst 3 to achieve good pressure on the uterine orifice, and being able to provide the effect of compressive hemostasis on the artery at the uterine orifice on the inner side of the vaginal fornix.

[0032] It further includes a lower force-bearing body 8 and an upper force-bearing body 10. The lower force-bearing body 8 is fixedly installed on the side wall of the drainage lower tube 9 to provide support for the arc-shaped cyst 501. The upper force-bearing body 10 is fixedly installed on the side wall of the drainage lower tube 9 to provide support for the balloon 4 and the branch cyst 502. The lower force-bearing body 8 is located below the upper force-bearing body 10. An upper support surface 1001 is provided on the side wall of the upper force-bearing body 10, and an upper ring part 801 and a lower ring part 803 are provided on the side wall of the lower force-bearing body 8. A lower support surface 802 is provided between the upper ring part 801 and the lower ring part 803. Both the upper support surface 1001 and the lower support surface 802 can provide support force. Reference Figure 9 , Figure 7 , Figure 5, the upper support surface 1001 is used to contact the branch bladder 502 and provide a supporting force, so that the reaction force acts on the lower drainage tube 9; the upper ring part 801 and the lower ring part 803 can limit the bottom position of the arc bladder 501 to prevent the bottom of the arc bladder 501 from moving, and the lower support surface 802 contacts the arc bladder 501 to provide a supporting surface. And in the contracted state, the lower force body 8, the upper ring part 801 and the lower ring part 803 can also provide guiding and limiting for the arc bladder 501, ensuring that in the contracted state, the smallest space can be occupied, which is convenient for placement in the uterus. The lower support surface 802 and the upper support surface 1001 are both gradually expanded from top to bottom to facilitate the provision of an upwardly inclined supporting force; the maximum radius of the upper force body 10 is greater than the radius of the upper drainage tube 301, and the maximum radius of the lower force body 8 is greater than the maximum radius of the upper force body 10. Therefore, a gradually expanding cross-section will be formed, which can facilitate placement into the uterine orifice; the liquid or gas both come from an external filling device, and the filling device is a prior art for providing a liquid source and a gas source.

[0033] Working principle: During use, the intrauterine bladder 3, the balloon 4, the arc bladder 501, the branch bladder 502, and the vaginal bladder 2 are all in a contracted state, and the whole can be operably inserted into the uterus through the main body duct 1 from the vagina; Step 1, inject liquid or gas into the intrauterine bladder 3 through the main body branch pipe 101 through the main body duct 1, so that the intrauterine bladder 3 initially compresses and stops bleeding on the uterine inner wall. After the hydraulic pressure or air pressure reaches the preset value, close the control valve on the main body branch pipe 101. The blood in the uterus is pushed by the intrauterine bladder 3 to the upper drainage tube 301, and then guided to the outside through the lower drainage tube 9; Step 2: Inject liquid or gas into the vaginal bladder 2 through the vaginal bladder duct 201. The disc-shaped part 202 of the vaginal bladder 2 is used to fit the vaginal inner wall to provide a supporting force for the whole, prevent the whole from falling off, and improve the hemostasis stability; while the surrounding part 203 contacts the vaginal inner wall, its upper part can surround the uterine orifice and apply pressure to the uterine orifice from outside to inside, cooperating with the intrauterine bladder 3 to achieve good pressure on the uterine orifice; Step 3: Control the rotation of the lower drainage tube 9 through the operation ring 901, and the lower drainage tube 9 drives the micro electronic camera 6 to rotate synchronously to observe the uterine inner wall for one week. Since the intrauterine bladder 3 contacts the uterine inner wall, the field of view will not be blocked by blood and water, and it is possible to directly observe whether there are still bleeding sites after the initial compression hemostasis; Step 4: If there are bleeding sites, select to use the balloon 4 and / or the targeted component 5 according to the bleeding site, and rotate the balloon 4 and / or the targeted component 5 to the bleeding site; Liquid or gas is injected into the arc-shaped bladder body 501 and the branch bladder body 502 through the arc-shaped bladder duct 503. The arc-shaped bladder body 501 and the branch bladder body 502 expand under the action of the liquid or gas, and can perform secondary targeted pressure on the intrauterine bladder body 3 from the inside to the outside. The expanded branch bladder body 502 can be in contact with the upper support surface 1001 of the upper force-bearing body 10, providing a support force for the arc-shaped bladder body 501 and improving the support effect. Liquid or gas is injected into the balloon body 4 through the balloon duct 401. The balloon body 4 expands under the action of the injected liquid or gas, and the balloon body 4 provides fixed-point pressure on the part of the uterine cavity of the intrauterine bladder body 3 close to the fallopian tube, so that the intrauterine bladder body 3 can compress the part of the uterine cavity close to the fallopian tube, avoiding positions where pressure cannot be applied. Step Five: Under the deformation support action of the balloon body 4, the arc-shaped bladder body 501 and the branch bladder body 502, the deformation thrust generated synchronously by the pushing part 307 causes the accommodating cavity 303 to be pressurized, and the liquid hemostatic drug sprays out from the gap between the release part 305 and the upper pressing part 304. Due to the obstruction of the uterine inner wall, part of this liquid medicine directly falls on the uterine inner wall, and part of it will flow to the outer surface of the outer elastic layer 302, which can directly act on the bleeding site and play a role in drug hemostasis. The drug groove 308 is arranged in the warp direction. The liquid hemostatic drug flowing to the outer surface of the outer elastic layer 302 can flow into the drug groove 308, and the liquid hemostatic drug at different positions can be evenly dispersed through the drug groove 308, maximizing the utilization of the liquid hemostatic drug. The continuous design enables the liquid hemostatic drug to flow to the entire drug groove 308. The characteristics are that the liquid hemostatic drug has a long flow path and a wide action surface, thus completing compression and drug hemostasis. Embodiment

[0034] Reference Figure 11 , the difference from the first embodiment is that: The drug groove 308 is distributed along the warp direction and is intermittently arranged. The intermittent arrangement can limit the flow range of the liquid drug, can concentrate the use of the liquid hemostatic drug, and improve the hemostatic effect of a certain part. This method can reduce the number of accommodating cavities 303 provided and reduce the production cost.
