Description

Technical Field

[0001] This application relates to the technical field of medical devices, specifically an ovarian chocolate cyst aspiration separator. Background Art

[0002] Ovarian chocolate cysts, also known as endometriosis cysts, are a common gynecological disease. It occurs because endometrial tissue grows outside the uterine cavity and bleeds with the change of the menstrual cycle. The blood accumulates in the ovary, forming an old hematoma, which gets its name because of its color and texture similar to chocolate. Under ultrasound guidance, accurately locate the position of the cyst, ensure that the puncture path avoids important organs and blood vessels, perform local anesthesia at the puncture site to relieve the patient's pain, use a sterile puncture needle to slowly penetrate into the cyst along the predetermined path. After confirming that the tip of the needle is inside the cyst, connect the syringe and start aspirating the fluid inside the cyst, slowly aspirate the old blood and other fluids inside the cyst until the cyst significantly shrinks.

[0003] According to a conveniently operable fluid aspiration and detection syringe pointed out by Chinese Publication No.: CN219148681U, which includes a syringe barrel and a piston rod member placed inside the syringe barrel. A drain pipe is communicated on the outer peripheral surface of the syringe barrel; wherein, a liquid pipe is connected below the drain pipe through a connecting component; in the present utility model, through the sealing component inside the tube cap, when the tube cap is separated from the drain pipe, the sealing component can seal the tube cap to avoid the entry of dust and impurities, further improving the preservation ability of the fluid, effectively avoiding the problem of the fluid being affected by the outside. Secondly, in the present utility model, the tube cap and the tube body are detachably connected. When it is necessary to detect the fluid inside the tube body, the tube cap can be directly rotated to separate the tube cap from the tube body. At this time, the fluid inside the tube body can be directly detected without pouring out the fluid for detection, which can further optimize the detection process of the operating personnel.

[0004] During the aspiration process with a syringe, the size of the patient's cyst will cause different consumption times during the aspiration process. Because during the aspiration process, the hand of the doctor holding the piston rod needs to move slowly to ensure that the patient's body does not feel discomfort. When facing a patient with a relatively large cyst volume, it will lead to a longer aspiration time. During the long-term process of the doctor holding the piston rod, it will cause the hand to spasm and have a transient twitching phenomenon. When this phenomenon occurs in the hand, it is easy for the piston rod to be affected by the hand twitching and cause the piston rod to push or aspirate, resulting in discomfort for the patient. Summary of the Invention

[0005] The purpose of the present application is to provide an ovarian chocolate cyst aspiration separator to solve the problem proposed in the above background technology that when facing a patient with a relatively large cyst volume, the extraction time will be longer.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] The following will be further described in detail in conjunction with the attached Figure 1-8 This application embodiment is further described in detail.

[0041] Example 1

[0042] Please refer to Figure 1 to Figure 8 , this embodiment provides a technical solution: an ovarian chocolate cyst aspiration separator, including: a syringe 1, a one-way flow component 2, a hose 3, a puncture needle 4, a pressing block 5, a piston rod 6, a positioning component 7, a closing component 8, a collection and sampling component 9, and an exhaust component 10;

[0043] The main body of the aspiration and separation device consists of a syringe 1, a hose 3 with one end arranged outside the syringe 1, a puncture needle 4 arranged at the other end of the hose 3, pressing blocks 5 integrally formed at both ends of the outer wall of the syringe 1, and a piston rod 6 slidably connected inside the syringe 1. An insertion pipe is integrally formed on the outer wall of the syringe 1. A hole is provided on the outer wall of the syringe 1 at the position of the pressing block 5, and a groove is provided inside one group of the pressing blocks 5;

[0044] Both ends of the one-way flow component 2 are respectively arranged at the liquid inlet of the syringe 1 and one end of the hose 3.

[0045] The positioning component 7 is arranged in the groove of one group of the pressing blocks 5. The positioning component 7 includes a toothed groove 701 opened on the outer wall of the piston rod 6, a rotating shaft 702 bonded to one side of the inner wall of the groove of the pressing block 5, an "L"-shaped block 703 rotatably connected to the rotating shaft 702. The "L"-shaped block 703 is provided with a rectangular hole, a second positioning plate 704 bonded to the other side of the inner wall of the groove of the pressing block 5. The second positioning plate 704 is provided with a through hole, a connecting block 705 slidably connected in the through hole of the second positioning plate 704, a tooth block 706 slidably connected in the through hole of the second positioning plate 704. The tooth block 706 is connected to the connecting block 705, a second spring 707 sleeved outside the tooth block 706, and both ends of the second spring 707 are respectively attached to the outer walls of the second positioning plate 704 and the tooth block 706;

[0046] One end of the closing component 8 is arranged on the insertion pipe of the syringe 1, the collection and sampling component 9 is fixedly arranged at the other end of the closing component 8, and the exhaust component 10 is arranged at one end of the outer wall of the piston rod 6.

[0047] Connect the puncture needle 4 to the flexible tube 3. The flexible tube 3 is connected to the syringe 1 through the one-way flow component 2. At this time, insert the puncture needle 4 into the position of the cyst in the patient's body. The doctor presses the positioning component 7 inside the pressing block 5 with one hand. Only then can the doctor hold the piston rod 6 with the other hand to perform the extraction work. When the hand of the doctor holding the piston rod 6 spasms, release the hand pressing the positioning component 7 at this time, and the piston rod 6 can be kept from moving further inside the syringe 1. And through the one-way flow component 2, it can be ensured that the liquid extracted through the flexible tube 3 will not flow back into the patient's body. When the cyst of the patient is relatively large, at this time, by opening the closing component 8, the liquid collected inside the syringe 1 can be transported to the inside of the collection and sampling component 9 through the closing component 8 to achieve collection and subsequent sampling work. Through the exhaust component 10, it can provide for the piston rod 6 to reciprocate inside the syringe 1, so as to effectively perform extraction and cleaning at one time when facing a relatively large cyst of the patient.

[0048] When the hand of the doctor holding the piston rod 6 spasms, at this time, the doctor releases the hand pressing the "L"-shaped block 703 inside the pressing block 5. When the "L"-shaped block 703 is no longer pressed, the second spring 707 on one side of the second positioning plate 704 will push the tooth block 706. When the tooth block 706 moves, it provides for the tooth block 706 to engage with the tooth-shaped groove 701 of the piston rod 6, thereby positioning the piston rod 6 and avoiding the phenomenon of accidental touch. When the piston rod 6 needs to continue to move, at this time, press the "L"-shaped block 703. During the movement of the "L"-shaped block 703, it can rotate through the rotating shaft 702. When the "L"-shaped block 703 rotates, it can drive the connecting block 705 in the rectangular hole to change its position. Because the connecting block 705 is connected to the tooth block 706, it provides for the tooth block 706 to no longer be pushed by the second spring 707 and thus no longer engage with the tooth-shaped groove 701.

[0049] Embodiment 2

[0050] Please refer to Figure 1 to Figure 3 , this embodiment provides a technical solution: an ovarian chocolate cyst aspiration separator, including: a first tube 201, a first "×"-shaped block 202, a first rod 203, a first baffle 204, a first positioning plate 205 and a first spring 206;

[0051] The one-way flow component 2 includes a first tube 201 with both ends sleeved and inserted on the syringe 1 and the hose 3 respectively, a first "×" shaped block 202 welded to one side of the inner wall of the first tube 201. A hole is provided in the central part of the first "×" shaped block 202. A first rod 203 is slidably connected in the hole of the first "×" shaped block 202 and a first baffle 204 welded to one end of the first rod 203. A sealing ring is adhered to one side of the outer wall of the first baffle 204, and holes for liquid flow are provided around the outside of the first baffle 204.

[0052] A first positioning plate 205 welded to the other side of the inner wall of the first tube 201. A hole slightly smaller than the diameter of the sealing ring of the first baffle 204 is provided in the central part of the first positioning plate 205. A first spring 206 is sleeved on the first rod 203, and both ends of the first spring 206 are respectively attached to the outer walls of the first "×" shaped block 202 and the first baffle 204.

[0053] When it is necessary to reciprocally move the piston rod 6 inside the syringe 1 to increase the amount of liquid extracted, at this time, a suction force will be generated during the movement and extraction of the piston rod 6 inside the syringe 1. This suction force will drive the first baffle 204 inside the first tube 201 to move through the first rod 203 inside the first "×" shaped block 202. At this time, affected by the suction force, the first baffle 204 will no longer be continuously pushed by the extrusion of the first spring 206, and thus will no longer continue to fit against the hole of the first positioning plate 205. When the piston rod 6 moves outward and extracts inside the syringe 1, it provides liquid to flow into the syringe 1. When the piston rod 6 moves inward inside the syringe 1, the pressure generated at this time will cooperate with the first spring 206, so that the first baffle 204 and the first positioning plate 205 are hermetically fitted, thus blocking the first tube 201. When the piston rod 6 moves inward inside the syringe 1, when there is still liquid left inside the syringe 1, the liquid will be pushed by the pressure and conveyed into the collecting tube 903.

[0054] Embodiment 3

[0055] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 This embodiment provides a technical solution: an ovarian chocolate cyst aspiration separator, including: a second tube 801, a "Z" shaped plate 802, and a threaded rod 803;

[0056] The closing assembly 8 includes a second tube 801 with one end sleeved and inserted on the insertion tube of the syringe 1. A threaded hole is provided at the top of the second tube 801. A "Z"-shaped plate 802 is welded at the central part inside the second tube 801. A round hole is provided at the central part of the "Z"-shaped plate 802. A threaded rod 803 is threadedly connected in the threaded hole of the second tube 801, and a sealing plug is bonded to the bottom of the threaded rod 803.

[0057] When the cyst in the patient's body is relatively large, at this time, by turning the threaded rod 803 on the second tube 801, after the threaded rod 803 generates displacement, it no longer continues to block and seal the hole of the "Z"-shaped plate 802 inside the second tube 801. At this time, the syringe 1 can deliver the liquid inside to the inside of the "Y"-shaped tube 901 through the second tube 801.

[0058] Embodiment 4

[0059] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , this embodiment provides a technical solution: an ovarian chocolate cyst aspiration separator, including: a "Y"-shaped tube 901, a sampling block 902 and a collection tube 903;

[0060] The collection and sampling assembly 9 includes a "Y"-shaped tube 901 with one end inserted and fixed at the other end of the second tube 801, a sampling block 902 and a collection tube 903 integrally formed and connected to the other two sets of pipes of the "Y"-shaped tube 901 respectively, and one end of the sampling block 902 is made of rubber material.

[0061] After the second tube 801 delivers the liquid inside to the inside of the "Y"-shaped tube 901, the "Y"-shaped tube 901 is connected to the collection tube 903, so as to deliver the liquid to the inside of the collection tube 903 for collection. When it is necessary to sample the collected liquid at intervals, the doctor inserts the needle on another syringe into the elastic rubber block of the sampling block 902, and then the liquid in the "Y"-shaped tube 901 can be extracted and collected.

[0062] Embodiment 5

[0063] Please refer to Figure 2 、 Figure 7 and Figure 8 , this embodiment provides a technical solution: an ovarian chocolate cyst aspiration separator, including: an exhaust hole 1001, a third tube 1002, a second baffle 1003, a third positioning plate 1004, a plug 1005 and a third spring 1006;

[0064] The exhaust assembly 10 includes an exhaust hole 1001 opened inside the piston rod 6 at the end where the piston block is bonded, and a third pipe 1002 integrally formed on the outer wall of the piston rod 6 at the end where the piston block is bonded.

[0065] A second baffle 1003 integrally formed on one side of the inner wall of the third pipe 1002 and a third positioning plate 1004 integrally formed on the other side of the inner wall of the third pipe 1002. A hole is opened in the middle part of the second baffle 1003, a round hole is opened in the middle part of the third positioning plate 1004, and holes for gas discharge are opened around the outer wall of the third positioning plate 1004.

[0066] A plug 1005 slidably connected in the round hole of the third positioning plate 1004 and a third spring 1006 sleeved outside the plug 1005. One end of the plug 1005 is bonded with a sealing ring, and both ends of the third spring 1006 are respectively attached to the outer walls of the third positioning plate 1004 and the plug 1005.

[0067] At this time, when the piston rod 6 moves inward inside the syringe 1, the pressure generated at this time will push the plug 1005 to displace inside the third positioning plate 1004. At this time, the plug 1005 no longer continues to be affected by the third spring 1006 and continues to block the second baffle 1003 inside the third pipe 1002. At this time, the residual pressure gas inside the syringe 1 will be discharged externally through the exhaust hole 1001, thereby providing for the piston rod 6 to reciprocate inside the syringe 1.

[0068] The implementation principle of the ovarian chocolate cyst aspiration separator of the present application is as follows:

[0069] First, connect the puncture needle 4 to the hose 3, and the hose 3 is connected to the syringe 1 through the one-way flow component 2. At this time, insert the puncture needle 4 into the position of the cyst in the patient's body. The doctor presses the positioning component 7 inside the pressing block 5 with one hand, and only then can the doctor hold the piston rod 6 with the other hand to perform the extraction work. When the hand of the doctor holding the piston rod 6 spasms, at this time, release the hand pressing the positioning component 7, and the piston rod 6 can be kept from continuing to move inside the syringe 1, and through the one-way flow component 2, it can be ensured that the liquid extracted through the hose 3 will not flow back into the patient's body. When the cyst volume of the patient is relatively large, at this time, by opening the closing component 8, the liquid collected inside the syringe 1 can be transported to the inside of the collection and sampling component 9 through the closing component 8 to achieve collection and subsequent sampling work. Through the exhaust assembly 10, it can provide for the piston rod 6 to reciprocate inside the syringe 1, so that when the cyst volume of the patient is relatively large, it can be effectively extracted and cleaned at one time.

[0070] Secondly, when the doctor's hand holding the piston rod 6 has a spasm, at this time the doctor releases the hand that was pressing the "L"-shaped block 703 inside the pressing block 5. When the "L"-shaped block 703 is no longer being pressed, the second spring 707 on one side of the second positioning plate 704 will push the toothed block 706. When the toothed block 706 is displaced, it will engage with the toothed groove 701 of the piston rod 6, thus positioning the piston rod 6 and preventing accidental contact. When the piston rod 6 needs to continue to move, at this time press the "L"-shaped block 703. During the movement of the "L"-shaped block 703, it can rotate through the rotating shaft 702. When the "L"-shaped block 703 rotates, it can drive the connecting block 705 in the rectangular hole to change its position. Since the connecting block 705 is connected to the toothed block 706, the toothed block 706 will no longer be pushed by the second spring 707 and will no longer engage with the toothed groove 701. When the cyst in the patient's body is relatively large, at this time rotate the threaded rod 803 on the second tube 801. After the threaded rod 803 is displaced, it will no longer block and seal the hole of the "Z"-shaped plate 802 inside the second tube 801. At this time, the syringe 1 can deliver the liquid inside to the inside of the "Y"-shaped tube 901 through the second tube 801. The "Y"-shaped tube 901 is connected to the collection tube 903, and the liquid is delivered to the inside of the collection tube 903 for collection. When it is necessary to sample the collected liquid at intervals, the doctor inserts the needle on another syringe into the elastic rubber block of the sampling block 902 to extract and collect the liquid in the "Y"-shaped tube 901.

[0071] Finally, when it is necessary to reciprocate the piston rod 6 inside the syringe 1 to increase the amount of liquid extracted, at this time, a suction force will be generated during the movement and extraction of the piston rod 6 inside the syringe 1. This suction force will drive the first baffle 204 inside the first tube 201 to move through the first rod 203 inside the first "×" shaped block 202. At this time, affected by the suction force, the first baffle 204 will no longer be continuously pushed by the first spring 206, and thus will no longer continue to fit against the hole of the first positioning plate 205. When the piston rod 6 moves outward and extracts inside the syringe 1, it provides liquid to flow into the syringe 1. When the piston rod 6 moves inward inside the syringe 1, the pressure generated at this time will cooperate with the first spring 206, so that the first baffle 204 and the first positioning plate 205 are hermetically fitted, thus blocking the first tube 201. When the piston rod 6 moves inward inside the syringe 1, when there is still liquid inside the syringe 1, the liquid will be pushed into the collection tube 903 by the pressure. When there is no liquid inside the syringe 1, at this time, when the piston rod 6 moves inward inside the syringe 1, the pressure generated will push the plug 1005 to displace inside the third positioning plate 1004. At this time, the plug 1005 will no longer be affected by the third spring 1006 to continue blocking the second baffle 1003 inside the third tube 1002. At this time, the residual pressure gas inside the syringe 1 will be discharged to the outside through the exhaust hole 1001, thus providing the reciprocating movement of the piston rod 6 inside the syringe 1.
