Description

Technical Field

[0001] The utility model belongs to the technical field of endometrial embryo transplantation, and more specifically relates to a device for embryo transplantation through the myometrium to the endometrium. Background Art

[0002] In current IVF embryo transfer technology, embryos are transferred via an embryo transfer tube, which is inserted through the cervix into a suitable location in the endometrium. The existing embryo transfer tube consists of two parts: an external catheter, which passes through the external cervical os and is inserted into the internal cervical os. The second part is the embryo transfer tube. During embryo transfer, the embryo is loaded into the embryo transfer tube, inserted through the external catheter into the endometrial implantation site, and then injected into the endometrium using a syringe.

[0003] Based on the above, the inventors have discovered the following problems: the outer tubes in most current endometrial embryo transfer devices are of fixed length. The length and position of the uterus of different patients may vary, and the existing outer tubes cannot adapt to different uterine anatomical structures, thereby reducing the adaptability of the operation and posing a risk of infection.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a device for embryo transplantation through the myometrium to the endometrium is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a device for embryo transplantation through the myometrium to the endometrium, so as to solve the problem that the existing outer tube cannot adapt to different uterine anatomical structures, thereby reducing the adaptability of the operation.

[0006] The purpose and efficacy of the device for embryo transfer through the myometrium to the endometrium of the present invention are achieved by the following specific technical means:

[0007] A device for embryo transplantation through the myometrium to the endometrium comprises an outer tube, an extension tube is mounted on one side of the outer tube, an outer sleeve is mounted on one side of the extension tube, the extension tube and the outer tube are pluggable connected, an embryo transplant catheter is mounted inside the outer tube, a syringe is mounted on one end of the embryo transplant catheter, and one end of the syringe is mounted inside the outer sleeve.

[0008] Furthermore, a connector is installed at one end of the extension tube, and the connector is plug-in connected to the outer tube.

[0009] Furthermore, one end of the outer sleeve can be plug-in connected to one end of the outer tube or the extension tube.

[0010] Furthermore, one end of the embryo transfer catheter is provided with a thread groove, one end of the syringe is provided with a thread, and the embryo transfer catheter is threadedly connected to the syringe.

[0011] Furthermore, the outer tube is made of silicone.

[0012] Furthermore, an ultrasonic wave reflecting surface is provided on the outer side wall of the top of the outer tube.

[0013] Furthermore, the embryo transfer catheter is provided with scale lines.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using the outer tube, extension tube, outer sleeve and connector in conjunction, in the endometrial embryo transfer device, if the outer tube is insufficiently long, the connector on the extension tube is inserted into the outer tube to lengthen the outer tube. The lengthened outer tube can reduce direct contact between the embryo transfer catheter and the endometrium, thereby reducing potential damage to the endometrium during the operation. Through the above design, the longer outer tube can provide better stability, prevent unnecessary movement of the embryo transfer catheter during the operation, ensure the precise placement of the embryo, and at the same time provide more adjustment space, allowing the doctor to better control the insertion depth and position of the embryo transfer catheter.

[0016] Through the coordinated use of the embryo transfer catheter, threaded groove, and syringe, when the syringe is used for a long time, the syringe may leak or become clogged. By turning the syringe to disengage the threaded groove, the syringe can be replaced. Through the above design, the threaded connection provides a firm fixation, reducing the risk of shaking or falling off during operation. At the same time, the new syringe has better sealing and materials, reducing the risk of leakage or gas entering the embryo transfer catheter, thereby reducing the possibility of infection or other complications.

[0025] As attached Figure 1 To the attached Figure 3 As shown:

[0026] The utility model provides a device for embryo transplantation through the myometrium to the endometrium, comprising an outer tube 1, an extension tube 2 being installed on one side of the outer tube 1, an outer sleeve 3 being installed on one side of the extension tube 2, the extension tube 2 and the outer tube 1 being plug-in connected, an embryo transplantation catheter 4 being installed inside the outer tube 1, a syringe 5 being installed at one end of the embryo transplantation catheter 4, and one end of the syringe 5 being installed inside the outer sleeve 3.

[0027] Among them, one end of the extension tube 2 is equipped with a connector 6, and the connector 6 is connected to the outer tube 1 through plugging. Through the coordinated use of the outer tube 1, the extension tube 2, the outer sleeve 3 and the connector 6, in the endometrial embryo transplantation device, if the length of the outer tube 1 is insufficient, the connector 6 on the extension tube 2 is inserted into the outer tube 1 to lengthen the length of the outer tube 1. The lengthened outer tube 1 can reduce the direct contact between the embryo transplant catheter 4 and the endometrium, and reduce the potential damage to the endometrium during the operation. Through the above design, the longer outer tube 1 can provide better stability, prevent the embryo transplant catheter 4 from unnecessary movement during the operation, ensure the precise placement of the embryo, and at the same time provide more adjustment space, so that the doctor can better control the insertion depth and position of the embryo transplant catheter 4.

[0028] One end of the outer sleeve 3 can be plugged and connected to one end of the outer tube 1 or the extension tube 2.

[0029] Among them, one end of the embryo transfer catheter 4 is provided with a threaded groove 7, and one end of the syringe 5 is provided with a thread. The embryo transfer catheter 4 is threadedly connected to the syringe 5. Through the coordinated use of the embryo transfer catheter 4, the threaded groove 7, and the syringe 5, when the syringe 5 is used for a long time, the syringe 5 may leak or be blocked. By rotating the syringe 5 to disengage the threaded groove 7, the syringe 5 can be replaced. Through the above design, the threaded connection provides a firm fixation, reducing the risk of shaking or falling off during operation. At the same time, the new syringe 5 has better sealing and material, reducing the risk of leakage or gas entering the embryo transfer catheter 4, thereby reducing the possibility of infection or other complications.

[0030] The outer tube 1 is made of silicone, which has good softness and can come into good contact with biological tissues, thus reducing stimulation to the endometrium.

[0031] Among them, an ultrasonic reflecting surface 8 is provided on the top outer side wall of the outer tube 1. Through the ultrasonic reflecting surface 8, the positioning is clear and accurate, and the precise positioning of the embryo transplantation can be achieved.

[0032] Wherein, the embryo transfer catheter 4 is provided with scale lines 9 .

[0033] The specific usage and function of this embodiment are as follows:

[0034] During use of the present invention, the integrity of the device is first confirmed. The length and position of the uterus of different patients may be different, and the length of the outer tube 1 needs to be adjusted. The connector 6 on the extension tube 2 is inserted into the outer tube 1 to lengthen the length of the outer tube 1. The lengthened outer tube 1 can reduce the direct contact between the embryo transfer catheter 4 and the endometrium, reducing potential damage to the endometrium during operation. At the same time, when the syringe 5 is used for a long time, the syringe 5 may leak or be blocked. By rotating the syringe 5 to disengage the syringe 5 from the threaded groove 7, the syringe 5 can be replaced. The threaded connection provides a firm fixation, reducing the risk of shaking or falling off during operation. Through the above design, the longer outer tube 1 can provide better stability, prevent the embryo transfer catheter 4 from unnecessary movement during operation, ensure the precise placement of the embryo, and provide more adjustment space, so that the doctor can better control the insertion depth and position of the embryo transfer catheter 4.
