Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of embryo transfer, in particular to an embryo transfer auxiliary device. Background Art
[0002] Embryo transfer, also known as fertilized egg transfer, refers to the technology of transplanting early embryos in the body of female animals, or embryos obtained by in vitro fertilization and other methods, into the bodies of other female animals of the same species with the same physiological conditions, so that they continue to develop into new individuals. Mastering the distance between the position where the embryo is transplanted into the uterus and the uterine fundus can improve the success rate of embryo implantation. The embryo transfer tube is a sterile device for delivering embryos into the uterine cavity during the IVF cycle, and is generally made of non-toxic plastic tubes.
[0003] In embryo transfer, under normal circumstances, during transplantation, medical staff in the embryo laboratory hand the inner tube containing the embryo to the doctor. However, the doctor needs to hold the outer tube of the transfer tube in one hand and place it in the speculum and hold it steady, which makes it inconvenient for the doctor to pick up the inner tube and perform the injection operation of the embryo solution. Therefore, currently in embryo transfer, medical staff in the embryo laboratory need to place the inner tube in the outer tube and push the liquid containing the embryo into the patient's body, which causes crowding during the operation process. Two people crowd together to perform the operation, and the outer tube and the inner tube need to be fixed by hand throughout the process. Moreover, during the transplantation process, it is not a simple straight in and out, but needs to be slowly pushed along various bends in the body. In this way, it is more inconvenient to find the injection position in the patient's body, and it greatly consumes the doctor's physical strength and reduces work efficiency.

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0023] Figures 1 to 5 The following shows an embodiment of the utility model.
[0024] Embodiment 1:
[0025] An embryo transfer assisting device includes a vaginal speculum 1, and further includes a support tube 2 installed inside the vaginal speculum 1. One end inside the support tube 2 extends to the outside of the vaginal speculum 1, and an installation ring 3 is connected at the end. A fixing plate 4 is installed on the installation ring 3. One end of the fixing plate 4 is positioned at the pipe orifice of the support tube 2 and is connected with a fixing catheter 5. Fixing pieces 6 are installed on the inner wall of the fixing catheter 5. When performing embryo transfer, the vaginal orifice is opened through the vaginal speculum 1. Then, the support tube 2 is installed into the expanded vaginal speculum 1. Next, the outer tube for embryo transfer is installed into the fixing catheter 5 and is fixed by the fixing pieces 6 inside the fixing catheter 5. In this way, the outer tube can be stably fixed inside the fixing catheter 5. Even if it is necessary to take the inner tube or perform other operations, the outer tube can be loosened without worrying about the movement of the outer tube, solving the problem in the prior art that during the embryo transfer process, medical staff need to hold the outer tube and the inner tube throughout the process. When the outer tube is fixed, after the inner tube is inserted into the outer tube and enters the human body during the embryo transfer process, the inner tube can also be briefly loosened without worrying about the movement of the inner tube.
[0026] The fixing plate 4 is installed on the installation ring 3 through a fixing screw 7. A long strip hole 8 penetrating both sides is arranged along the length direction of the fixing plate 4. A threaded hole 9 is arranged on the side of the installation ring 3 away from the vaginal speculum 1. One end of the fixing screw 7 passes through the long strip hole 8 and is threadedly matched and connected with the threaded hole 9. The end of the fixing screw 7 away from the threaded hole 9 is connected with a knob plate 10, and the knob plate 10 cooperates with the installation ring 3 to clamp the fixing plate 4. With such a setting, during use, the fixing position of the fixing plate 4 can be adjusted through the cooperation of the fixing screw 7 and the knob plate 10, thereby adjusting the position of the fixing catheter 5. By reversely screwing the knob plate 10, the gap between the knob plate 10 and the installation ring 3 is increased, so that the fixing plate 4 can be moved arbitrarily by means of the long strip hole 8, thereby adjusting the position of the fixing catheter 5. After adjusting to a suitable position, the knob plate 10 is screwed to make the knob plate 10 cooperate with the installation ring 3 to clamp the fixing plate 4.
[0027] A rubber layer 11 is arranged on the side of the knob plate 10 facing the fixing plate 4; a handle plate 12 is arranged at the end of the fixing plate 4 away from the fixing catheter 5. By arranging the rubber layer 11, the friction between the fixing plate 4 and the knob plate 10 is increased, thereby enhancing the firmness of fixation and preventing the fixing plate 4 from loosening easily. By arranging the handle plate, it is convenient for the operator to hold the fixing plate 4 when adjusting the fixing plate 4.
[0028] The fixing plate 6 is installed on the inner wall of the fixed conduit 5 through the slide bar 13. The fixed conduit 5 is provided with a sliding hole 14 that penetrates inside and outside on one side facing the fixed plate 4. The slide bar 13 is slidably installed in the sliding hole 14. One end of the slide bar 13 is connected to the fixing plate 6 in the fixed conduit 5, and the other end is connected to a paddle 15 on the outside of the fixed conduit 5. The outer wall of the slide bar 13 is sleeved with a spring 16 between the fixing plate 6 and the inner wall of the fixed conduit 5. Since the size of the outer tube varies according to different manufacturers, but the diameter is within a certain range, the fixing plate 6 and the inner wall of the fixed conduit 5 are used to clamp the outer tubes of different sizes to achieve the fixation of the outer tubes of different sizes. When installing the outer tube, the paddle 15 is moved away from the fixed conduit 5, so that the gap for fixing the outer tube in the fixed conduit 5 can be increased, and then the outer tube is inserted, the paddle 15 is loosened, and the fixing plate 6 is pushed by the elastic force of the spring 16 to slightly clamp the fixing plate 6, so that the outer tube will not slide easily in the fixed tube.
[0029] The fixing plate 6 is arc-shaped, and a first silicone layer 17 is provided on the side of the fixing plate 6 away from the slide rod 13, and a second silicone layer is provided around the inner wall of the fixed conduit 5. With the help of the arc-shaped fixing plate 6, the surface of the outer tube can be better fitted. By providing the first silicone layer 17 and the second silicone layer, the friction with the surface of the outer tube can be increased, and at the same time, damage to the outer tube can be avoided when the outer tube slides.
[0030] The outer wall of the support tube 2 disposed on one end of the outside of the vaginal dilator 1 is provided with a first thread, and the inner wall of the mounting ring 3 is provided with a second thread matching the first thread. This arrangement can facilitate the disassembly and installation of the mounting ring 3.
[0031] The support tube 2 includes a fixed section 18 and an elastic support plate 19 connected in sequence, the mounting ring 3 is connected to one end of the fixed section 18, and a plurality of elastic support plates 19 are arranged around the end of the fixed section 18 away from the mounting ring 3. Since the opening size of the vaginal speculum 1 needs to be adjusted according to actual conditions, the utility model adopts a plurality of elastic support plates 19 to be installed in the vaginal speculum 1, and the elastic force of the plurality of elastic support plates 19 expanding outwards is used to fit the inner side of the vaginal speculum 1, so as to fix the support tube 2 in the vaginal speculum 1. The advantage of this is that the support tube 2 can be easily installed in the vaginal speculum 1 and removed from the vaginal speculum 1.
[0032] The outer sides of the plurality of elastic support plates 19 are all provided with rubber strips 20. By providing the rubber strips 20, the friction between the elastic support plates 19 and the inner wall of the vaginal dilator 1 can be increased, so as to facilitate the stability of the installation of the support tube 2.
[0033] There are two sets of a fixing plate 4 and a fixing conduit 5 provided on the mounting ring 3. In addition to being used for fixing the outer tube, the fixing conduit 5 can also be added with one for fixing a lighting lamp. After adjusting the orientation of the lamp and fixing it in the fixing conduit 5, it is possible to perform lighting without the need for an operator to hold it by hand.
