Description

Technical Field

[0001] The present invention relates to the technical field of reproductive medicine, and more specifically, to an artificial insemination and transplantation device for reproductive medicine. Background Art

[0002] Cervical appearance and structure differences: Cervix of non-childbearing women: The external orifice of the cervix of non-childbearing women is usually round, and the cervical tissue is relatively firm. The length of the cervical canal is generally about 2.5 - 3 cm. Its mucosa is single-layer columnar epithelium, and the secreted mucus is relatively viscous during the non-ovulatory period, which can effectively prevent pathogens from entering the uterus. During artificial insemination, the cervical orifice is relatively small, and more care and precision are required when inserting the catheter to avoid damaging the cervical tissue.

[0003] Cervix after childbirth: The external orifice of the cervix of multiparous women is in a transverse fissure shape, which is a permanent morphological change caused by the fetus passing through the cervical orifice during childbirth. The cervix is relatively loose, and the cervical canal may be slightly shorter. This loose state makes it relatively easier to insert the insemination catheter during artificial insemination.

[0004] The possibility and cause of sperm reflux: The cervix of multiparous women is relatively loose, and there is indeed a possibility of sperm reflux. During artificial insemination, when the liquid containing sperm is injected into the uterine cavity, due to the loose cervical orifice and insufficient resistance to prevent the liquid from flowing out, part of the semen may reflux out along the cervical orifice.

[0005] This is mainly because childbirth causes changes in the cervical morphology and elasticity, making the cervix unable to seal the uterine cavity contents as well as that of non-childbearing women. In addition, the cervical canal of multiparous women may be shorter, which also reduces the natural barrier for semen to stay in the uterine cavity.

[0006] Existing artificial insemination and transplantation devices for reproductive medicine have a single function and cannot effectively adapt to the fitting operations of the external orifices of the cervix after childbirth and non-childbirth. In view of this, we propose an artificial insemination and transplantation device for reproductive medicine. Summary of the Invention

[0007] The purpose of the present invention is to provide an artificial insemination and transplantation device for reproductive medicine to solve the technical problem of the single function of existing artificial insemination and transplantation devices for reproductive medicine.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: an artificial insemination and transplantation device for reproductive medicine, comprising a body; the internal gap of the body constitutes an operating chamber; the operating chamber is sequentially provided with a pump control mechanism, a constraint adjustment mechanism, and a basic propulsion mechanism; and the power input ends of the constraint adjustment mechanism and the basic propulsion mechanism are both provided with a driving micro-motor with gears; the output end of the operating chamber is provided with a probe transplantation catheter; wherein the probe transplantation catheter is a multi-layer structure; and a main transplantation cavity for semen transfer and transportation is opened at the axis of the probe transplantation catheter; the end of the probe transplantation catheter It has a trapezoidal structure; and a slitting head is movably provided at the end of the probe transplant catheter; a traction rope is fixedly provided on the slitting head; wherein, the traction rope is wound and connected with the constraint adjustment mechanism; the outer surface of the probe transplant catheter is provided with peristaltic cavity walls and deformation support cavity walls alternately provided in sequence along the axial direction of the probe transplant catheter; and, several of the peristaltic cavity walls are connected to the control end of the pump control mechanism through the shunt cavity tube A; and, several of the deformation support cavity walls are connected to the other control end of the pump control mechanism through the shunt cavity tube B; the probe transplant catheter has a peristaltic propulsion state and a separated stacking state.

[0009] The present invention adjusts and controls the probe and transplantation catheter so that the probe and transplantation catheter has a peristaltic propulsion state to perform relatively gentle and flexible penetration work on the undelivered cervical os, and based on the characteristics of peristaltic movement, effectively reduces the damage to the cervical os caused by the conventional rigid propulsion process; and in conjunction with the separated and stacked state of the probe and transplantation catheter, the probe and transplantation catheter forms an axial area enlargement operation at a controllable distance position, and can be temporarily left in the uterus to block the internal cervical os after delivery, thereby reducing sperm reflux and insufficient sperm transplantation caused by uterine contraction, and effectively improving the adaptability functionality.

[0010] Preferably, the pump control mechanism includes a control connecting pump body installed at the axial end of the operating chamber; suction adjustment channels are arranged on both sides of the control connecting pump body; wherein, the two suction adjustment channels are respectively connected with the diversion cavity A and the diversion cavity B; a piston push rod is arranged inside the suction adjustment channel; a toggle adjustment frame connected to the ball head at the end of the piston push rod; wherein, a flip adjustment frame is slidably arranged on the outer wall of the toggle adjustment frame, and the toggle adjustment frame and the flip adjustment frame are key-connected; and a flip drive motor is arranged on one side of the flip adjustment frame; the ball head inside the toggle adjustment frame is connected with an axial adjustment screw sleeve; the axial adjustment screw sleeve is threadedly connected to the control connecting pump body.

[0011] Preferably, the constraint adjustment mechanism includes a plurality of rotating frames evenly distributed at equal intervals in a ring shape; the adjacent rotating frames are connected by an arc-shaped rail frame body; a rotating track cavity is formed by the gaps between the plurality of arc-shaped rail frame bodies; a main drive disk is movably arranged on the rotating track cavity, and a plurality of output drive protrusions are arranged at the end of the main drive disk; a plurality of input meshing teeth are arranged on the side of the main drive disk; a winding wheel is rotatably arranged on the rotating frame; a plurality of spiral grooves that are extrusion-fitted with the output drive protrusions are arranged at equal intervals in a ring shape on the inner wall of the winding wheel; the winding wheel is fixedly connected with the traction rope.

[0013] Preferably, a plurality of pushing blocks evenly distributed at equal intervals in a ring shape are arranged at the end of the propulsion sleeve; a force-bearing contact protrusion in a triangular shape is arranged at the middle end of the pushing block; and the pushing block has an obtuse angle structure.

[0014] Preferably, the cross-section of the peristaltic cavity wall is composed of two cavity A's with a triangular structure; and the large-head end of the cavity A at the position where the peristaltic cavity wall is relatively far from the output end of the probing and implanting catheter is locally connected to the radial side of the probing and implanting catheter.

[0017] Preferably, the constraint adjustment mechanism winds up the traction rope, causing the cutting head to separate from the peristaltic cavity wall, the deformable support cavity wall and the inserted transplantation catheter.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By adjusting and controlling the inserted transplantation catheter, the present invention enables the inserted transplantation catheter to have a peristaltic propulsion state to perform relatively gentle and flexible penetration work on the undeveloped cervical orifice, and effectively reduces the damage to the cervical orifice caused by the conventional rigid propulsion process based on the characteristics of peristaltic movement; and in cooperation with the separated stacked state of the inserted transplantation catheter, the present invention enables the inserted transplantation catheter to increase the axial area at a controllable distance position, which can be temporarily left in the uterus to block the internal cervical orifice after childbirth, reduce sperm reflux and insufficient sperm transplantation caused by uterine contraction, and effectively improve the adaptability and functionality.

[0020] 2.

[0021] 3. One of the drive micro-motors with gears drives the main drive disk to rotate, so that the output drive protrusion squeezes the spiral groove, forcing the winding wheel to rotate, to realize the winding work of the traction rope fixed on the winding wheel.

[0022] 4.

[0023] 5. Through the setting of the force-bearing extrusion block, when the propulsion sleeve slides close sufficiently, the bifurcated end of the push block contacts the inclined surface of the force-bearing extrusion block, and the force-bearing extrusion block fully unfolds through the force-bearing extrusion block, so that the force-bearing contact protrusion cannot interfere with the movement of the inserted transplantation catheter, facilitating the peristaltic propulsion operation.
