Description

Technical Field

[0001] The invention relates to the technical field of puncture and egg retrieval, and in particular to special protective equipment for puncture and egg retrieval in reproductive medicine. Background Art

[0002] Egg retrieval is an operation in assisted reproductive technology, usually used for in vitro fertilization. In this process, the doctor will use a fine needle through the vaginal wall under ultrasound guidance, directly into the ovary, and extract eggs from the follicles. This process is usually performed after the woman's ovaries are stimulated by hormones to produce multiple follicles. Egg retrieval is a minimally invasive surgery, usually performed under local anesthesia to reduce discomfort and pain. In order to facilitate the puncture and egg retrieval, a puncture stand for auxiliary puncture will be installed on the outside of the ultrasound probe to ensure accurate puncture and avoid damage to the patient.

[0003] In order to increase the chance of successful pregnancy, the doctor may recommend removing multiple eggs at one time so that more eggs can be used for fertilization and embryo culture. Removing multiple eggs at one time can reduce the number of egg retrieval cycles that the patient needs to go through, thereby reducing the physical and emotional burden. However, the risk of removing multiple eggs at one time and the difficulty of the operation are greater than that of removing a single egg. After removing one egg, before aspirating another egg, the egg retrieval needle needs to be retracted to avoid damage to the patient by the egg retrieval needle during the process of changing the puncture position. However, the retraction distance of the puncture needle is difficult to control. After retraction, the medical staff relies on hand-held positioning. When moving the ultrasonic probe after retracting the egg retrieval needle, if the position of the hand-held puncture needle is not properly controlled, the needle will extend from the puncture stand, causing harm to the patient. The patient's safety cannot be effectively guaranteed during the process of removing multiple eggs at one time. Therefore, the present application provides a special protective equipment for reproductive puncture and egg retrieval to meet the needs. Summary of the invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting the deformation zone and the limiting component, when multiple eggs are retrieved at one time, during the process of the egg retrieval needle retreating into the puncture tube, the deformation zone can, under the action of the limiting component, block and limit the needle tip of the egg retrieval needle retreating into the puncture tube, thereby preventing the needle tip of the egg retrieval needle from extending out of the puncture tube and scratching the patient when the ultrasonic probe changes position, thereby ensuring the safety of the egg retrieval process and ensuring the protection effect on the patient.

[0018] By setting up the positioning component, medical staff can position the transmission plate through the positioning component when inserting the egg retrieval needle into the puncture tube for puncture and egg retrieval, and then let the deformation zone bend and deform to form an avoidance for the needle tip of the egg retrieval needle, so as to facilitate the puncture and egg retrieval operation. At the same time, by observing the position of the paddle, it can also be confirmed that the needle tip has retracted to a safe position during the retraction process of the needle tip, thereby further ensuring the safety of the equipment during use.

[0019] By providing the second weakened groove and the first guide surface in the positioning assembly, when the positioning plate in the positioning assembly switches its position between the first positioning groove and the second positioning groove, medical staff can move the paddle to deform the paddle at the second weakened groove, so that the positioning plate is away from the outside of the insertion head, making the operation of the positioning assembly simple and convenient, and easy for medical staff to operate.

[0020] By setting up a liquid collecting component, when the needle of the egg retrieval needle is retracted into the puncture tube, the outside of the egg retrieval needle is scraped and cleaned by the cleaning end of the rubber sleeve, and the tissue fluid contaminated on the egg retrieval needle is scraped off and stored in the liquid collecting tank. When the egg retrieval needle punctures the ovary again, the outside of the egg retrieval needle is scraped and cleaned again, and the tissue fluid scraped off previously is sealed, so as to prevent the egg retrieval needle from bringing the tissue fluid into the patient's tissue during the second puncture, reduce the patient's infection risk, and further improve the protection effect of the equipment.

[0021] By providing a rubber sleeve, a cleaning end and a sealing ring, when the rubber sleeve is not affected by external force and the egg retrieval needle punctures the ovary, the cleaning end is pulled by the elastic force of the elastic sheet so that the outer portion of the cleaning end fits with the sealing ring, thereby ensuring that the rubber sleeve seals the tissue fluid in the liquid collecting tank. During the process of the egg retrieval needle retreating into the puncture tube, the egg retrieval needle drives the cleaning end to stretch the elastic sheet, thereby opening the gap between the rubber sleeve and the liquid collecting tank and the sealing ring, thereby facilitating the collection and storage of tissue fluid. This makes the structure of the liquid collecting component simple and ingenious, and utilizes the puncture and retreat actions of the egg retrieval needle to achieve scraping, cleaning, collection and sealing of tissue fluid.

[0044] like Figures 1 to 13As shown, an embodiment of the present invention provides a protective device specifically for puncture and egg retrieval in the reproductive department, comprising a puncture tube 1 and an egg retrieval needle 5, the outer sleeve of the egg retrieval needle 5 is provided with a fixing clamp 2 and a fixing frame 3, and one end of the puncture tube 1 is fixedly connected to an insertion head 4, the fixing clamp 2 and the fixing frame 3 on the puncture tube 1 are used to connect and fix with the ultrasonic probe, the puncture tube 1 is assembled on the ultrasonic probe, and the puncture tube 1 can be changed synchronously with the ultrasonic probe after being fixed, and the puncture position is adjusted, so as to retrieve eggs at different positions, the egg retrieval needle 5 is sleeved in the puncture tube 1, the puncture tube 1 is fixedly connected with a fixing tube 6 and an extension plate 7, and the outer part of the fixing tube 6 is fixedly connected with a transmission plate 8 A deformation zone 9 is provided at one end of the transmission plate 8 close to the fixed tube 6, and the end of the transmission plate 8 away from the fixed tube 6 extends to the outside of the insertion head 4 and is fixedly connected with a paddle 11. The deformation zone 9 can limit the egg retrieval needle 5 located in the puncture tube 1. When not affected by external force, the deformation zone 9 can just form a shield for the needle tip of the egg retrieval needle 5 at the position of the puncture tube 1, thereby preventing the egg retrieval needle 5 from retreating into the puncture tube 1 and, when the ultrasonic probe changes position, extending from the puncture tube 1 to scratch the patient. The paddle 11 can drive the deformation zone 9 to deform and avoid through the transmission of the transmission plate 8, thereby facilitating the egg retrieval needle 5 to pass normally through the puncture tube 1 and perform puncture and egg retrieval.

[0045] The positioning component is used to fix the relative position of the paddle 11 and the insertion head 4, and the positioning component is connected to the paddle 11; the limiting component is used to maintain the position of the deformation zone 9 in the puncture tube 1 to form a limit on the needle head of the egg retrieval needle 5, and the limiting component is connected to the deformation zone 9; the liquid collecting component is used to collect the tissue fluid contaminated on the egg retrieval needle 5, and the liquid collecting component is connected to the fixed tube 6. The positioning component can fix the position of the paddle 11 to maintain the deformation state of the transmission plate 8 after the paddle 11 is moved, so that during the normal puncture and egg retrieval process of the egg retrieval needle 5, the deformation zone 9 can produce the corresponding The corresponding avoidance will not affect the normal operation of the egg retrieval needle 5. The limiting component can limit the deformation zone 9 when the deformation zone 9 is not affected by external force, ensuring that the bottom end of the deformation zone 9 can cover the needle head of the egg retrieval needle 5. The liquid collecting component can scrape the tissue fluid contaminated on the egg retrieval needle 5 into the liquid collecting tank 27 for storage during the process of the needle head of the egg retrieval needle 5 retreating into the puncture tube 1, and scrape and clean the outside of the egg retrieval needle 5 again during the process of the egg retrieval needle 5 puncturing the ovary again, so as to prevent the egg retrieval needle 5 from bringing the tissue fluid into the patient's tissue during the second puncture, reduce the patient's infection risk, and further improve the protection effect of the equipment.

[0046] In this embodiment, if Figures 1 to 5As shown, the puncture tube 1 and the insertion head 4 are provided with a first guide groove 16 adapted to the size of the egg retrieval needle 5, and the puncture tube 1 is provided with a protection zone 15 adapted to the size of the fixed tube 6 and the extension plate 7. The first guide groove 16 in the puncture tube 1 and the insertion head 4 can accommodate the passage of the egg retrieval needle 5. During the passage of the egg retrieval needle 5 through the first guide groove 16, its outer portion is in close contact with the inner wall of the first guide groove 16, so that the first guide groove 16 provides guidance for the movement of the egg retrieval needle 5, ensuring the accuracy of the egg retrieval needle 5 during the puncture and egg retrieval process. The protection zone 15 is provided to provide space for the installation of the fixed tube 6 and the extension plate 7. The deformation zone 9 on the transmission plate 8 is also in the protection zone 15. The diameter of the protection zone 15 is greater than the diameter of the first guide groove 16, so that there is still a certain gap between the egg retrieval needle 5 and the inner wall of the protection zone 15 during the passage of the egg retrieval needle 5 through the protection zone 15. This gap provides space for the deformation zone 9 to avoid. To allow the deformation zone 9 to form an avoidance during the puncture and egg retrieval process of the egg retrieval needle 5, so as to avoid affecting the normal operation of the egg retrieval needle 5, a second guide groove 17 adapted to the shape of the transmission plate 8 is provided in the puncture tube 1, and an active groove 19 connected to the second guide groove 17 is provided on the insertion head 4. The end of the transmission plate 8 away from the fixed tube 6 is bent in an L shape and is located in the active groove 19, and the transmission plate 8 is provided with evenly distributed lightweight holes. The shifting paddle 11 can drive the deformation zone 9 to bend and deform in the protection zone 15 through the transmission of the transmission plate 8, so as to adapt to different working states of the egg retrieval needle 5. Correspondingly, during the retreat of the egg retrieval needle 5, after the positioning of the paddle 11 is released, it is also possible to judge whether the egg retrieval needle 5 has retreated into place by observing the position of the paddle 11. When the egg retrieval needle 5 retreats into place, it is not released from the outside of the deformation zone 9, and the deformation zone 9 can restore the deformation, forming a shielding limit for the needle head of the egg retrieval needle 5, to avoid the needle head slipping out and causing danger.

[0047] In this embodiment, if Figures 2 to 6As shown, the positioning assembly includes a positioning plate 12 fixedly connected to the paddle 11, a first positioning groove 13 and a second positioning groove 14 adapted to the shape of the positioning plate 12 are provided on the insertion head 4, a first guide surface 18 is provided on one side of the first positioning groove 13 facing the second positioning groove 14, the paddle 11 is Z-shaped, one end of the paddle 11 is in contact with the outside of the insertion head 4, and the other end of the paddle 11 is separated from the outside of the insertion head 4, and the positioning plate 12 is fixedly connected to the paddle 11 At the bottom of the end separated from the insertion head 4, when the positioning plate 12 is embedded in the first positioning groove 13, the deformation zone 9 is in a natural state, not affected by external forces, and the needle head of the egg retrieval needle 5 is shielded in the protection zone 15. When the positioning plate 12 is embedded in the second positioning groove 14, the paddle 11 is fixed by the positioning plate 12, and the deformation zone 9 is in a stretched state, forming a avoidance for the egg retrieval needle 5, which facilitates the sliding operation of the egg retrieval needle 5 in the puncture tube 1. The end of the paddle 11 that is in contact with the insertion head 4 The area value is greater than the area value at the opening of the movable groove 19, and a second weakened groove 24 is opened in the middle of the paddle 11. The second weakened groove 24 on the paddle 11 makes the paddle 11 thinner and weaker in strength at this location, making it easier to deform after being acted upon by an external force. In the process of pushing the paddle 11 in the direction of the second positioning groove 14, the first guide surface 18 in the first positioning groove 13 can decompose the resistance received by the positioning plate 12, and then cause it to be pushed upward. At this time, the positioning plate 12 can drive the paddle 11 to bend and deform at the second weakened groove 24 until the positioning plate 12 slides out of the first positioning groove 13 and enters the second positioning groove 14. When the fixed state of the positioning assembly needs to be released, the paddle 11 can be bent and deformed at the second weakened groove 24 when the paddle 11 is toggled, so that the positioning plate 12 is separated from the second positioning groove 14, and then the paddle 11 and the positioning plate 12 are driven to reset under the action of the elastic force of the deformation zone 9 itself, making the entire operation process of the positioning assembly simple and easy.

[0048] In this embodiment, if Figures 8 to 10As shown, the limit assembly includes a support sheet 10 symmetrically mounted on the deformation zone 9, the deformation zone 9 is arc-shaped, and the bottom end of the deformation zone 9 corresponds to the central axis position of the puncture tube 1, the thickness of the deformation zone 9 is less than the thickness of other areas on the transmission plate 8, so the strength of the deformation zone 9 is weaker, and the transmission plate 8 is pulled by the paddle 11 during the sliding process, and can be bent correspondingly at the deformation zone 9. When the deformation zone 9 is not subject to external force, the bottom end position is at the central axis of the puncture tube 1, which is also the middle area of ​​the protection zone 15. In this state, the deformation zone 9 can block the needle tip of the egg retrieval needle 5, so that the needle tip of the egg retrieval needle 5 cannot pass through the deformation zone 9, thereby ensuring that the needle tip will not slip out of the puncture tube 1 and scratch the patient after retreating before the second egg retrieval operation is performed. The end of the support sheet 10 and the end of the support sheet 10 of the protection zone 15 are inclined toward the inner wall of the protection zone 15. When the deformation zone 9 is in a natural state, the end of the support sheet 10 is in contact with the inner side wall of the protection zone 15 to provide support for the deformation zone 9, thereby maintaining the deformation zone 9 in a shielding state against the needle head of the egg retrieval needle 5. A uniformly distributed first weakening groove 22 is provided on one side of the deformation zone 9 where the support sheet 10 is installed, and a convex strip 23 matching the shape of the first weakening groove 22 is provided at the end of the support sheet 10. The first weakening groove 22 provided on the deformation zone 9 further weakens the structure of the deformation zone 9, thereby making it easier for the paddle 11 to be moved without being too strenuous. The deformation zone 9 is in an avoidance state and is stretched and deformed by the transmission plate 8 driven by the paddle 11. At this time, the support sheet 10 is also squeezed and bent to fit the inner side wall of the protection zone 15. The convex strip 23 on the support sheet 10 is inserted into the first weakening groove 22 on the deformation zone 9, and cooperates with the deformation of the deformation zone 9 to form an avoidance for the egg retrieval needle 5 to puncture and retrieve eggs.

[0049] In this embodiment, if Figures 11 to 13 As shown, the liquid collecting assembly includes a rubber sleeve 25 fixedly connected to the inner side of the fixed tube 6, the position of the extension plate 7 corresponds to the position of the deformation zone 9, the cross-section of the extension plate 7 is arc-shaped, and a third guide surface 21 is provided at the end of the extension plate 7, and a second guide surface 20 is provided at one end of the fixed tube 6 facing the extension plate 7. During the process of the needle tip of the egg retrieval needle 5 transferring from the first guide groove 16 to the protection zone 15, the gap between the needle tip and the protection zone 15 can easily cause the position of the needle tip to shift. The third guide surface 21 on the extension plate 7 and the second guide surface 20 on the fixed tube 6 are both used to guide the movement of the needle tip, ensuring that the needle tip of the egg retrieval needle 5 corresponds to the central axis position of the puncture tube 1 when it extends from the puncture tube 1, thereby ensuring the accuracy of puncture and egg retrieval.

[0050] One end of the rubber sleeve 25 is connected to the inner side wall of the fixed tube 6 through a connecting end 31, and the other end of the rubber sleeve 25 is in an open structure and forms a cleaning end 32. The size of the cleaning end 32 is adapted to the size of the egg retrieval needle 5. The thickness of the rubber sleeve 25 gradually decreases from the connecting end 31 to the cleaning end 32. A third weakening groove 30 is provided on the outer side of the middle of the rubber sleeve 25. The third weakening groove 30 forms a weakening on the outside of the rubber sleeve 25. When the cleaning end 32 is subjected to the friction of the egg retrieval needle 5 and flips or stretches, the rubber sleeve 25 can be deformed at the third weakening groove 30. In cooperation with the movement of the cleaning end 32, the rubber sleeve 25 and the fixed tube 6 The connection between the inner walls is the connecting end 31, which has a larger thickness value, and also makes the strength of the rubber sleeve 25 higher at this point, ensuring the connection effect between the rubber sleeve 25 and the inner wall of the fixed tube 6. The thickness value at the cleaning end 32 is thinner and the strength is weaker. In the process of the egg retrieval needle 5 passing through the cleaning end 32, it can be tightly fitted on the outside of the egg retrieval needle 5 to form a package, and then follow the sliding of the egg retrieval needle 5 to achieve scraping and cleaning of the outside of the egg retrieval needle 5, and scrape off the tissue fluid remaining on the outside of the egg retrieval needle 5, to avoid the residual tissue fluid on the egg retrieval needle 5 following the egg retrieval needle 5 into the patient's tissue to cause infection during repeated punctures, thereby further improving the protection effect of the equipment.

[0051] A liquid collecting tank 27 surrounding the outside of the rubber sleeve 25 is provided in the fixed tube 6, and a sealing ring 29 matched with the size of the cleaning end 32 is fixedly connected to the fixed tube 6. A connecting port 28 is provided on one side of the liquid collecting tank 27 close to the rubber sleeve 25, and the position of the sealing ring 29 corresponds to the position of the connecting port 28. An evenly distributed elastic sheet 26 is fixedly connected between the rubber sleeve 25 and the inner side wall of the liquid collecting tank 27. When the egg retrieval needle 5 is withdrawn, a large amount of tissue fluid remains on its outside, so it is necessary to open a liquid collecting tank 27 in the fixed tube 6 for storage. At the same time, in order to prevent the tissue fluid in the liquid collecting tank 27 from leaking out and adhering to the outside of the egg retrieval needle 5 when the egg retrieval needle 5 is punctured and egg retrieval is performed again, an elastic sheet 26 and a sealing ring 29 are provided, so that when the egg retrieval needle 5 is in the puncture and egg retrieval state, The rubber sleeve 25 can maintain the fit between the cleaning end 32 and the sealing ring 29 under the action of the elastic force of the elastic sheet 26, thereby forming a closure for the gap between the liquid collecting tank 27 and the rubber sleeve 25, and preventing the tissue fluid that has entered the liquid collecting tank 27 from leaking out. When the egg retrieval needle 5 is withdrawn from the gap, the cleaning end 32 is flipped toward the center of the rubber sleeve 25 by the friction force of the outside of the egg retrieval needle 5, and the gap between the rubber sleeve 25 and the sealing ring 29 is opened, so that the tissue fluid scraped by the cleaning end 32 can enter the liquid collecting tank 27 from the connecting port 28. At this time, the elastic sheet 26 is in a stretched state, and the flipping of the cleaning end 32 is limited to prevent the cleaning end 32 from flipping excessively and bringing a large amount of tissue fluid into the inner side of the rubber sleeve 25, affecting the cleaning effect of the rubber sleeve 25 on the outside of the egg retrieval needle 5 when the egg retrieval needle 5 is punctured.

[0052] The working principle of the technical solution provided by the present invention is as follows:

[0053] When in use, open the fixing clip 2 and wrap the fixing clip 2 around the outside of the ultrasonic probe as a whole, press the fixing frame 3 onto the outside of the ultrasonic probe near the end, snap the fixing clip 2 together and lock it to fix the puncture tube 1, take out the egg retrieval needle 5, insert the egg retrieval needle 5 from the insertion head 4, push the egg retrieval needle 5 forward after entering the puncture tube 1, and hold the ultrasonic probe for scanning and adjusting the position until the position for puncture and egg retrieval is determined.

[0054] By moving the paddle 11, the positioning plate 12 is driven to move from the first positioning groove 13 to the second positioning groove 14. The end of the transmission plate 8 slides in the movable groove 19 following the movement of the paddle 11. The transmission plate 8 causes the deformation zone 9 to bend and deform, and squeezes the support plate 10 until the positioning plate 12 is snapped into the second positioning groove 14. The support plate 10 is completely fitted with the inner wall of the protection zone 15, and the deformation zone 9 is deformed to avoid the egg retrieval needle 5, and the egg retrieval needle 5 is continuously pushed to an egg to perform the puncture and egg retrieval operation.

[0055] After one egg is taken out, when a second egg retrieval is needed, the paddle 11 is moved again, so that the paddle 11 bends and deforms at the second weakened groove 24 and drives the positioning plate 12 to withdraw from the second positioning groove 14, and the transmission plate 8 and the paddle 11 are unlocked, and the egg retrieval needle 5 is withdrawn. The deformed area 9 after the positioning is released is pressed against the outside of the egg retrieval needle 5 until the egg retrieval needle 5 is withdrawn to a safe position. The deformed area 9 recovers its deformation under the action of the support plate 10, and the paddle 11 and the positioning plate 12 are also completely reset. At this time, the position of the ultrasonic probe is changed again, the puncture position is adjusted, and then the above operation is repeated to perform multiple egg retrievals.

[0056] During the withdrawal operation of the egg retrieval needle 5, the outside of the egg retrieval needle 5 is contaminated with the patient's tissue fluid and then slides into the protection area 15. The cleaning end 32 area on the rubber sleeve 25 contacts the outside of the egg retrieval needle 5, and is rolled toward the center of the fixed tube 6 by the friction force of the egg retrieval needle 5, opening the gap between the sealing ring 29 and the cleaning end 32. At the same time, the cleaning end 32 scrapes off the tissue fluid on the outside of the egg retrieval needle 5. After the tissue fluid passes through the gap, it passes through the connecting port 28 and enters the liquid collecting tank 27 for storage. After the egg retrieval needle 5 is away from the rubber sleeve 25, the elastic sheet 26 drives the cleaning end 32 to reset under the action of its own elastic force, so that the cleaning end 32 is in contact with the sealing ring 29 again, and the tissue fluid stored in the liquid collecting tank 27 is sealed.

[0057] When the egg retrieval needle 5 performs the puncture and egg retrieval operation again, the inner wall of the cleaning end 32 scrapes and cleans the outside of the egg retrieval needle 5 again, further reducing the tissue fluid brought out by the egg retrieval needle 5. At the same time, the cleaning end 32 is further squeezed toward the cleaning end 32 by the friction force of the egg retrieval needle 5, making the cleaning end 32 and the sealing ring 29 more tightly closed, preventing the tissue fluid in the liquid collecting tank 27 from leaking out and adhering to the egg retrieval needle 5 and following the egg retrieval needle 5 to pierce the patient's tissue, further preventing infection, and completing the entire use process of the reproductive puncture and egg retrieval special protective equipment.
