Description

Technical Field

[0001] This utility model relates to the field of reproductive assisted device technology, specifically to an egg retrieval device for clinical reproductive use. Background Technology

[0002] An oocyte retrieval device is a medical instrument specifically used in reproductive medicine to puncture follicles in the ovaries to obtain oocytes. It typically consists of a puncture needle, a needle handle, and a collection tube, used to aspirate the oocytes. The oocyte retrieval device plays a crucial role in assisted reproductive technology (ART), forming the basis for derivative technologies such as in-vitro fertilization and embryo transfer.

[0003] Current clinical reproductive oocyte retrieval devices can accurately puncture follicles under ultrasound guidance, and then collect oocytes using a negative pressure adsorption device and an oocyte retrieval needle. However, because the adsorption process only targets the oocytes with the oocyte retrieval needle, it is easy to adsorb other tissues in the ovary, thereby causing unnecessary damage to the patient's ovary.

[0004] In summary, how to solve the problem that existing oocyte retrieval devices used in reproductive clinical practice, which focus solely on adsorbing the target oocyte during the oocyte adsorption process, can easily adsorb other tissues within the ovary, thus causing unnecessary damage to the patient's ovary, has become a pressing issue in this field. Therefore, it is necessary to propose an oocyte retrieval device for reproductive clinical practice that can improve adsorption accuracy. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an oocyte retrieval device for clinical reproductive use. Through the design of a fixed block and a hinge block, the oocyte retrieval needle can be better aligned with the patient's oocytes while protecting other ovarian tissues. This prevents the needle from adsorbing other tissues within the ovary while simultaneously adsorbing the oocytes, thereby reducing damage to the patient's ovaries during the oocyte retrieval process.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A reproductive clinical oocyte retrieval device includes an oocyte retrieval needle and a shell. A handle is fixedly connected to one end of the shell. A push handle is hinged to the side wall of the handle. A push rod is hinged to the side wall of the push handle. The end of the push rod away from the push handle passes through the shell and slides with the side wall of the shell. A support rod is fixedly connected to the end of the shell away from the handle. A fixed block is fixedly connected to the end of the support rod away from the shell. A rotating block is hinged to the fixed block. An arc-shaped groove is opened on the fixed block. A connecting rod slides within the groove. The top of the connecting rod is hinged to the end of the push rod away from the shell. The bottom of the connecting rod is fixedly connected to the rotating block. The oocyte retrieval needle is located between the fixed block and the rotating block. An oocyte storage cavity is opened inside the shell. The oocyte retrieval needle communicates with the oocyte storage cavity and extends through the shell to the space between the fixed block and the rotating block. An adsorption component for adsorbing oocytes is provided on the oocyte storage cavity.

[0007] The basic principle of the above scheme is as follows:

[0008] Once the retrieval needle reaches the patient's vaginal fornix, the doctor grips the handle and pusher, simultaneously pushing the entire device forward. This allows the needle to penetrate the ovary through the vaginal fornix. At the same time, the support rod and pusher push the fixed block and rotating block into the ovary along with the retrieval needle. After identifying the patient's oocyte using ultrasound positioning, the doctor aligns the retrieval needle with the oocyte. At this point, the doctor slowly releases the handle and pusher, pushing the pusher forward. The pusher pushes the pusher rod, which in turn pushes the connecting rod to slide in the groove. The connecting rod then rotates the rotating block, positioning the oocyte between the fixed block and the rotating block. The doctor then gently presses down on the surrounding tissue using the fixed block and the rotating block. Finally, the adsorption assembly is activated to adsorb the oocyte.

[0009] The above approach has the following beneficial effects:

[0010] 1. This utility model, through the design of a fixed block and a rotating block, allows the ovarian tissue surrounding the patient's oocytes to be gently pressed down by the fixed block and the rotating block during oocyte retrieval. This ensures that the oocytes are adsorbed only during the adsorption process, greatly reducing the impact on other tissues around the oocytes and thus minimizing damage to the patient's ovaries during oocyte retrieval, thereby improving the accuracy of adsorption.

[0011] 2. Through the design of the fixed block and the rotating block, this utility model can prevent the egg retrieval needle from causing unnecessary damage to the patient's vagina due to angle deviation during the insertion of the egg retrieval needle into the patient's body, thereby improving the safety of the egg retrieval process and reducing the risk of postoperative infection.

[0012] Furthermore, the adsorption assembly includes a controller and a control valve that is fixedly connected to the oocyte storage cavity, with the input end of the control valve electrically connected to the output end of the controller.

[0013] Beneficial effects: The control valve can be used to connect to a negative pressure adsorption device. After the controller opens the control valve, negative pressure can be generated by the negative pressure adsorption device to adsorb the patient's oocytes.

[0014] Furthermore, both the fixed block and the rotating block have flexible protective layers fixedly connected to their surfaces.

[0015] Beneficial effects: The flexible protective layer can further improve the protection of the fixed block and rotating block for the patient, and reduce the damage caused by the movement of the fixed block and rotating block in the patient's body.

[0016] Furthermore, a spring is fixedly connected between the handle and the push handle.

[0017] Beneficial effects: The spring design allows doctors to adjust the opening and closing of the rotating block and the fixed block with one hand; doctors only need to adjust the force of their hand gripping the handle and the push rod, and the spring will tighten as the doctor's grip force increases and expand as the grip force decreases, thereby driving the push rod to retract or extend, and thus driving the rotating block and the fixed block to close and open.

[0018] Furthermore, a one-way valve is fixedly connected at the junction of the oocyte storage cavity and the oocyte retrieval needle, and the input end of the one-way valve is electrically connected to the output end of the controller.

[0019] Beneficial effects: The one-way valve design ensures that during the adsorption process, the egg cells can only enter the storage cavity from the egg retrieval needle without backflow.

[0020] Furthermore, a heating plate is fixedly connected to the side wall of the oocyte storage cavity, and the input end of the heating plate is electrically connected to the output end of the controller.

[0021] Beneficial effects: Since the temperature inside the ovary is generally 36.5-37℃, doctors can control the heating temperature of the heating plate through a controller to keep the temperature of the ovarian cavity at 36.5-37℃. As women age, the ovarian temperature will also increase, but it will remain between 36.5-37℃. Therefore, doctors can make appropriate adjustments based on the patient's age and body temperature.

[0022] Furthermore, a camera is fixedly connected to the rotating block, and the camera's input end is electrically connected to the controller's output end.

[0023] Beneficial effects: The camera can enter the patient's body along with the rotating block, allowing the doctor to observe the patient's internal condition during the process, which helps the doctor to better adjust the puncture direction of the egg retrieval needle; during the egg retrieval process, the camera can capture images of the patient's ovary from different angles as the angle of the rotating block changes, allowing the doctor to observe the patient's ovary more comprehensively through the camera, determine the position of the egg cells, egg retrieval needle, fixation block, and rotating block, and perform the egg retrieval operation better.

[0024] Furthermore, an anti-slip layer is fixedly fitted onto the outer wall of the outer shell.

[0025] Beneficial effects: In existing technologies, doctors perform egg retrieval by holding a thin needle, which results in poor handling and makes the procedure difficult. The anti-slip layer increases the friction between the doctor's hand and the outer shell, allowing the doctor to better control the device and simplify the procedure.

[0026] Furthermore, the anti-slip layer is curved to fit the shape of the hand.

[0027] Beneficial effects: The curved design of the anti-slip layer allows the doctor's hand to better fit the anti-slip layer, thus providing a better grip on the outer shell and facilitating the doctor's operation.

[0028] Furthermore, the end of the egg retrieval needle furthest from the outer shell is engraved with an ultrasonic identification pattern.

[0029] Beneficial effects: The design of the ultrasound recognition pattern allows doctors to quickly identify the location of the egg retrieval needle using ultrasound equipment, improving the accuracy of the operation.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0037] The following detailed description illustrates the specific implementation method:

[0038] Example 1:

[0039] As attached Figures 1-4As shown: A reproductive clinical oocyte retrieval device includes an oocyte retrieval needle 6 and a shell 1. A handle 2 is screwed to one end of the shell 1. A push handle 3 is hinged to the side wall of the handle 2. A push rod 5 is hinged to the side wall of the push handle 3. The end of the push rod 5 away from the push handle 3 passes through the shell 1 and slides with the side wall of the shell 1. A support rod 4 is welded to the end of the shell 1 away from the handle 2. A fixing block 8 is welded to the end of the support rod 4 away from the shell 1. A rotating block 9 is hinged to the fixing block 8. An arc-shaped groove is opened on the fixing block 8. A connecting rod 10 slides in the groove. The top of the connecting rod 10 is hinged to the end of the push rod 5 away from the shell 1. The bottom of the connecting rod 10 and the rotating block 9 are integrally formed. The oocyte retrieval needle 6 is located between the fixing block 8 and the rotating block 9. An oocyte storage cavity is opened inside the shell 1. The oocyte retrieval needle 6 communicates with the oocyte storage cavity and extends through the shell 1 to the space between the fixing block 8 and the rotating block 9. An adsorption component for adsorbing oocytes is provided on the oocyte storage cavity.

[0040] The adsorption assembly includes a controller and a control valve 7 that is fixedly connected to the oocyte storage cavity screw. The input end of the control valve 7 is electrically connected to the output end of the controller. The control valve 7 is used to connect to the negative pressure adsorption device. In this embodiment, the preferred model of the controller is Simatic S7-200, the preferred model of the control valve 7 is KYK0526GL, and the negative pressure adsorption device is the adsorption needle tube in the prior art.

[0041] Both the fixed block 8 and the rotating block 9 have flexible protective layers fixedly bonded to their surfaces. The flexible protective layers can improve the protective effect of the fixed block 8 and the rotating block 9 on the patient and reduce the damage caused by the movement of the fixed block 8 and the rotating block 9 in the patient's body.

[0042] The specific implementation process is as follows:

[0043] by Figure 2 and Figure 3 For example, after the patient is anesthetized, before the doctor inserts the egg retrieval needle 6 into the patient's body, the doctor holds the handle 2 and the push handle 3 with one hand, so that the handle 2 and the push handle 3 are close to each other. At this time, the push rod 5 slides to the right side of the slide under the pull of the push handle 3, so that the fixed block 8 and the rotating block 9 are close to each other. The doctor holds the outer shell 1 with the other hand to control the insertion direction of the egg retrieval needle 6.

[0044] The doctor pushes the device forward so that the egg retrieval needle 6 enters the patient's body. At this time, the support rod 4 and the push rod 5 will push the fixed block 8 and the rotating block 9 into the patient's body together with the egg retrieval needle 6.

[0045] Once the oocyte retrieval needle 6 reaches the patient's vaginal fornix, the doctor grips the handle 2 and push handle 3, simultaneously pushing the entire device forward. This allows the oocyte retrieval needle 6 to penetrate the patient's ovary through the vaginal fornix. At the same time, the support rod 4 and push rod 5 simultaneously push the fixing block 8 and rotating block 9 into the patient's ovary along with the oocyte retrieval needle 6. After identifying the patient's oocytes using ultrasound positioning, the doctor aligns the oocyte retrieval needle 6 with the oocytes. At this point, the doctor slowly releases the handle 2 and push handle 3, pushing the push handle 3 forward. Because the push handle 3 and push rod 5 are hinged, the push handle 3 will push the push rod 5; and because the push rod 5 and connecting rod 10... The connecting rod 10 is hinged, and the top of the connecting rod 10 slides in the groove. Therefore, the push rod 5 will push the top of the connecting rod 10 to slide to the left in the groove. Since the rotating block 9 and the fixed block 8 are hinged, combined with the lever principle, the bottom of the connecting rod 10 will drive the rotating block 9 to rotate counterclockwise, so that the rotating block 9 moves away from the fixed block 8. At this time, the fixed block 8 and the rotating block 9 are aligned with the oocyte, and the ovarian tissue around the oocyte is gently pressed with the fixed block 8 and the rotating block 9. At this time, the suction needle is pulled. Since the oocyte retrieval needle 6 is connected to the oocyte storage cavity, the oocyte will be suctioned into the oocyte storage cavity.

[0046] During the adsorption process, since the egg cell is located between the fixed block 8 and the rotating block 9, and the fixed block 8 and the rotating block 9 gently press down on the other tissues around the patient's egg cell, this device only adsorbs the egg cell, greatly reducing the impact on other tissues around the patient's egg cell during the adsorption process, thereby reducing damage to the patient's ovary during egg retrieval and improving the accuracy of adsorption.

[0047] During the insertion of the egg retrieval needle 6 into the patient's body, the protective functions of the fixing block 8 and the rotating block 9 prevent the egg retrieval needle 6 from causing unnecessary damage to the patient's vagina due to angular deviation, thereby improving the safety of the egg retrieval process and reducing the risk of postoperative infection.

[0048] Example 2:

[0049] As attached Figures 1-2 As shown: Unlike the above embodiment, a spring 201 is fixedly connected between the handle 2 and the push handle 3 by screws.

[0050] The specific implementation process is as follows: The design of spring 201 allows the doctor to adjust the opening and closing degree of rotating block 9 and fixed block 8 with one hand; the doctor only needs to adjust the force of his hand gripping handle 2 and push handle 3; spring 201 expands as the doctor's hand grip decreases, causing push handle 3 to move away from handle 2, thereby pushing push rod 5 to move to the left, which in turn drives rotating block 9 to rotate, causing rotating block 9 and fixed block 8 to move away from each other; when the doctor's hand grip increases, spring 201 is compressed, which does not affect the rotation of push handle 3 and the retraction of push rod 5.

[0051] Example 3:

[0052] As attached Figure 1 As shown: Unlike the above embodiment, a one-way valve is fixedly connected to the connection between the oocyte storage cavity and the oocyte retrieval needle 6 by a screw, and the input end of the one-way valve is electrically connected to the output end of the controller; in this embodiment, the preferred model of the one-way valve is DF-T98.

[0053] The specific implementation process is as follows: During the adsorption process, the one-way valve ensures that the oocytes can only enter the oocyte storage cavity through the oocyte retrieval needle 6 without backflow, thereby improving the practicality of the device.

[0054] Example 4:

[0055] As attached Figure 1 As shown: Unlike the above embodiment, a heating plate is fixedly connected to the side wall of the ovipositor using screws, and the input end of the heating plate is electrically connected to the output end of the controller. In this embodiment, the preferred model of the heating plate is EH50-6040.

[0056] The specific implementation process is as follows: Since the temperature inside the ovary is generally 36.5-37℃, the doctor can control the heating temperature of the heating plate through the controller to keep the temperature of the oocyte storage cavity at 36.5-37℃. As women age, the ovarian temperature will also increase, but it will remain between 36.5-37℃. Therefore, the doctor will make appropriate temperature adjustments according to the patient's age and body temperature to maintain the activity of the oocytes.

[0057] Example 5:

[0058] As attached Figure 4 As shown: Unlike the above embodiment, a camera 11 is embedded in the rotating block 9, and the input terminal of the camera 11 is electrically connected to the output terminal of the controller. In this embodiment, the preferred model of the camera 11 is SY-936A5SH.

[0059] The specific implementation process is as follows: The camera 11 can enter the patient's body along with the rotating block 9. During the entry process, the camera 11 can observe the patient's internal condition, which makes it easier for the doctor to adjust the puncture direction of the egg retrieval needle 6. During the egg retrieval process, the camera 11 can take pictures of the patient's ovary from different angles as the angle of the rotating block 9 changes. This allows the doctor to observe the patient's ovary more comprehensively through the camera 11, determine the position of the egg cells, the egg retrieval needle 6, the fixing block 8, and the rotating block 9, and perform the egg retrieval operation better.

[0060] Example 6:

[0061] As attached Figure 5 As shown: Unlike the above embodiment, the outer wall of the outer shell 1 is fixedly adhesively fitted with an anti-slip layer 12, which is arc-shaped to fit the shape of the hand.

[0062] The specific implementation process is as follows: In existing technologies, doctors perform egg retrieval by holding a thin, long needle 6, which results in poor tactile feedback and makes the operation difficult. The anti-slip layer 12 increases the friction between the doctor's hand and the outer shell 1, allowing the doctor to better control the device and simplify the operation. Furthermore, the curved design of the anti-slip layer 12 allows the doctor's hand to better conform to the anti-slip layer 12, thus improving grip on the outer shell 1 and facilitating the operation.

[0063] Example 7:

[0064] As attached Figures 2-3 As shown: Unlike the above embodiment, the end of the egg retrieval needle 6 away from the outer shell 1 is engraved with an ultrasonic identification pattern.

[0065] The specific implementation process is as follows: When the doctor performs ultrasound examination, the design of the ultrasound recognition pattern allows the doctor to quickly identify the position of the egg retrieval needle 6 through the ultrasound equipment, improving the accuracy of the operation.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
