Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-5 A coreless, bendable embryo transfer tube includes a bendable inner tube 1, a cervical fixation member 2, and a straight outer tube 3. The cervical fixation member 2 is installed on the outer wall of the bendable inner tube 1, and the straight outer tube 3 is installed on the outer wall of the bendable inner tube 1. A stabilizing component 4 is installed on the outer wall of the straight outer tube 3. The stabilizing component 4 includes a limiting unit and a positioning unit. The limiting unit is located inside the straight outer tube 3, and the positioning unit is located on the outer wall of the straight outer tube 3.

[0026] The limiting unit includes an embryo tube 401, a track 402, a locking element 403, a protrusion 404, a baffle 405, and a spring 406. The embryo tube 401 is installed inside the straight outer tube 3. The track 402 is formed on the inner wall of the straight outer tube 3. The locking element 403 is located inside the track 402. The outer wall of the locking element 403 is slidably connected to the inner wall of the track 402. The outer wall of the locking element 403 is fixedly connected to the outer wall of the embryo tube 401. The locking element 403 can slide inside the track 402 as the embryo tube 401 moves, which can ensure the stability of the movement of the embryo tube 401. The protrusion 404 is installed on the outer wall of the locking element 403. One end of the protrusion 404 penetrates the locking element 403 and extends into the interior of the locking element 403. The outer wall of the protrusion 404 slides against the inner wall of the locking element 403 through which it is penetrated. The straight outer tube 3 has a notch inside. The end of the protrusion 404 away from the clamp 403 passes through the notch and is slidably connected to the inner wall of the notch. The protrusion 404 can slide inside the clamp 403. The protrusion 404 can fix the embryo tube 401 by passing through the notch. The baffle 405 is located inside the clamp 403. The outer wall of the baffle 405 is fixedly connected to the end of the protrusion 404 that extends into the clamp 403. The outer wall of the baffle 405 is slidably connected to the outer wall of the clamp 403. The spring 406 is fixedly connected to the outer wall of the baffle 405. The end of the spring 406 away from the baffle 405 is fixedly connected to the outer wall of the embryo tube 401. The spring 406 can apply a pushing force to the protrusion 404 through the baffle 405, so that the protrusion 404 can pass through the notch.

[0027] By setting the track 402 and the clip 403, when installing the embryo tube 401, the embryo tube 401 is moved by sliding, so that the clip 403 slides inside the track 402. At this time, the clip 403 will limit the rotation angle of the embryo tube 401, ensuring that the embryo tube 401 can move smoothly. When the protrusion 404 moves to the designated position, it will penetrate the straight outer tube 3 and extend to the outer wall of the straight outer tube 3. At this time, the protrusion 404 will limit the position of the embryo tube 401, solving the problem that existing embryo transfer tubes are prone to shaking during embryo transfer due to touching or other actions by medical staff, resulting in insufficient stability of the embryo transfer tube.

[0028] The positioning unit includes a housing 407, a movable rod 408, a pressing member 409, a movable plate 410, and a spring 411. The housing 407 is fixedly connected to the outer wall of the straight outer tube 3, and the interior of the housing 407 communicates with a notch. The movable rod 408 is installed on the outer wall of the housing 407, with one end penetrating through the housing 407 and extending into the interior of the housing 407. The outer wall of the movable rod 408 is slidably connected to the inner wall of the housing 407 through which it is penetrated, allowing the movable rod 408 to slide within the housing 407. The pressing member 409 is fixedly connected to one end of the movable rod 408. The movable plate 410 is located inside the housing 407. The outer wall of the movable plate 410 is fixedly connected to one end of the movable rod 408 extending into the inner wall of the outer shell 407. The outer wall of the movable plate 410 is slidably connected to the inner wall of the outer shell 407. The movable rod 408 can be driven to move the movable plate 410 by pushing the pressing member 409. The outer wall of the movable plate 410 abuts against the outer wall of the protrusion 404. The protrusion 404 can be pushed away from the notch by the movable plate 410 and enter the interior of the track 402, which facilitates the removal of the embryo tube 401. The second spring 411 is fixedly connected to the outer wall of the movable plate 410. The side of the second spring 411 away from the movable plate 410 is fixedly connected to the inner wall of the outer shell 407.

[0029] By setting up a pressing member 409 and a movable plate 410, when the protrusion 404 penetrates the straight outer tube 3, it will push the pressing member 409 to move through the movable plate 410, causing the pressing member 409 to be displaced. When it is necessary to disassemble the embryo tube 401, the pressing member 409 can be reset, so that the pressing member 409 pushes the movable plate 410 to reset through the movable rod 408. At this time, the protrusion 404 will move into the interior of the track 402 under the action of the movable plate 410, and then the embryo tube 401 can be disassembled.

[0030] The working principle of this coreless, bendable embryo transfer tube is as follows: After fixing the cervical fixation piece 2 to the patient's body surface, the bendable inner tube 1 and the straight outer tube 3 are installed. The embryo tube 401 is moved by sliding, so that the locking piece 403 slides inside the track 402. After moving to the designated position, the protrusion 404 will bulge under the action of the spring 406 and be locked inside the outer shell 407. The pressing piece 409 is moved by the movable plate 410 and the movable rod 408. After the embryo transfer is completed, the pressing piece 409 is moved, so that the movable plate 410 pushes the protrusion 404 back to its original position until the protrusion 404 moves into the track 402. At this time, the embryo tube 401 can be removed.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
