Detailed Description
The four-ball intrauterine device comprises a placer, the placer comprises a column body 1, the front end of the column body 1 is provided with a hemispherical end face 2, one side of the front end of the side wall of the column body 1 is provided with a containing cavity 3, one side of the column body 1 is provided with an arc sliding cover plate 4, two sides of the arc sliding cover plate 4 are provided with convex blocks 5, the column body 1 on two sides of the arc sliding cover plate 4 is provided with guide grooves 6, the convex blocks 5 are matched with the guide grooves 6 to enable the arc sliding cover plate 4 to slide along the length direction of the column body 1, the arc sliding cover plate 4 can shade the containing cavity 3, the containing cavity 3 is internally provided with a film 7, the width of the film 7 is the same as the width of the containing cavity 3, one end of the film 7 is connected with the outer side edge of the front end of the containing cavity 3, the other end of the film 7 is connected with the inner wall of the arc sliding cover plate 4, a contraceptive device 11 is arranged in the accommodating cavity 3 at one side of the film 7 close to the arc sliding cover plate 4, the contraceptive device 11 comprises a first sphere 12 and a second sphere 13, the first sphere 12 and the second sphere 13 are connected through a transverse tube 14, the first sphere 12 and the second sphere 13 are wound into a sphere by nickel-titanium memory alloy wires, the transverse tube 14 is spirally wound into a tube shape by nickel-titanium memory alloy wires, a transverse support 20 is arranged in the transverse tube 14, the transverse support 20 is contacted with the upper part of the inner wall of the transverse tube, the connecting middle part of the transverse tube 14 is connected with a hollowed-out flat sphere 17 through a first support rod 15 and a second support rod 16, the hollow oblate spheroid 17 is connected with a third spheroid 19 through a connecting rod 18, the cross support 20, the first supporting rod 15, the second supporting rod 16 and the hollow oblate spheroid 17 are all made of nickel-titanium memory alloy, the third spheroid 19 is made of a metal material containing nano copper, and the nickel-titanium memory alloy can restore the shape in the environment of 37 ℃. The placer according to the invention is usually disposable, and the structure of the contraceptive device 11 can be compressed transversely and stored in the housing chamber 3 of the placer, the placer and the contraceptive device being a unitary product. During the use, operation operating personnel send into the palace bottom position with the placer tip under the assistance of B ultrasonic, make arc slip apron 4 towards human left side or right side, then pull arc slip apron 4 backward, make arc slip apron 4 follow guide way 6 back move, hold chamber 3 and open, along with the back of arc slip apron 4, film 7 is strained gradually, can push out the contraceptive device 11 from holding chamber 3 to the space that forms between palace bottom and the oviduct mouth of pipe of placer side after the film 7 is strained, can withdraw from the placer this moment, resume the shape by oneself by contraceptive device 11. The placer can push out the intrauterine device 11 to a naturally formed space at one side of the uterine bottom near the mouth of the oviduct at the side surface, thereby avoiding damaging the uterine wall due to hard contact with the uterine wall in the pushing-out process of the intrauterine device 11. The contraceptive device 11 is mostly made of nickel-titanium memory alloy, the nickel-titanium memory alloy material can restore to the original shape by itself in the environment of 37 ℃ in human body, the third sphere 19 is made of metal material containing nano copper, the position of the third sphere corresponds to the cervical orifice in the uterine cavity, and the contraceptive device has the functions of killing sperms and preventing pregnancy. After the placer pushes the intrauterine device 11 out from the side surface to the side of the uterine bottom near the mouth of the oviduct, the placer withdraws from the uterus, and the transverse tube 14 and the transverse bracket 20 inside the transverse tube can provide a certain shape restoration elasticity, so that the intrauterine device 11 is primarily unfolded in the uterine cavity, and the phenomenon that all parts are mutually blocked to influence the recovery of the intrauterine device when the nickel-titanium memory alloy recovers the shape is avoided. After the contraceptive device 11 is restored, the ball structure can form a three-dimensional structure, so that the relative space of the contraceptive device 11 in the uterus is enlarged, the weight of the contraceptive device 11 can be lightened by matching the ball structure with the tube structure, the local compression on the uterus is reduced, and the hollow ball can be filled with a slow release medicament according to the requirement for relieving inflammatory reaction generated after operation.
In order to prevent the arc-shaped sliding cover plate 4 from accidentally sliding, a circular groove 22 can be arranged at the rear end of the cylinder 1, a knob 23 is arranged in the circular groove 22, the end part of the knob 23 protrudes out of the circular groove 22, the middle part of the knob 23 is connected with the main body 1 through a rotating shaft 24, one side of the circular groove 22 is provided with a long through hole 25, a limiting rod 26 is arranged in the long through hole 25, the limiting rod 26 is connected with the knob 23, the inner wall of the arc-shaped sliding cover plate 4 is provided with a limiting groove 27, and when the knob 23 rotates, the end part of the limiting rod 26 can be driven to enter or move out of the limiting groove 27. Before the end part of the placer reaches the uterine bottom, the limiting rod 26 is always positioned in the limiting groove 27, so that the position of the arc-shaped sliding cover plate 4 is locked, and the arc-shaped sliding cover plate 4 is prevented from accidentally sliding. After the end of the placer reaches the uterine fundus, the operator can rotate the knob to move the end of the limiting rod 26 out of the limiting groove 27, and at this time, the arc-shaped sliding cover plate 4 can be moved backwards under the operation of the operator.
