Description

Technical Field

[0001] This application relates to the field of contraceptive devices, and more particularly to a processing apparatus for an intrauterine device and a support spring. Background Technology

[0002] An intrauterine device (IUD), also known as a contraceptive ring, is a common method of contraception. It is a small plastic or copper device placed inside a woman's uterus to prevent pregnancy by releasing copper ions or preventing sperm from entering the uterus.

[0003] In related technologies, the IUD mainly consists of a plastic support and copper wire wound around it. Depending on the specific application, different molds are needed to manufacture and injection mold plastic supports of various shapes to meet diverse usage requirements.

[0004] The aforementioned technologies have led to the manufacture of various types of IUDs, which can be used in a wide range of situations. However, this has resulted in a significant increase in production costs, necessitating improvements. Summary of the Invention

[0005] In order to improve the problem of the increased production cost caused by manufacturing a variety of IUDs to suit different usage conditions in related technologies, this application provides a processing device for IUDs and support springs.

[0006] Firstly, this application provides an intrauterine device (IUD) using the following technical solution:

[0007] An intrauterine device (IUD) includes a copper wire and a support spring, wherein shape memory ribs are threaded through the support spring and the copper wire is wound around the support spring.

[0008] By adopting the above technical solution, in practical applications, medical personnel can bend the shape memory rib into the desired shape, while the supporting spring will be supported by the shape memory rib and conform to its contour. Simultaneously, after the IUD is inserted into the uterus, the copper wire will release copper ions to perform normal contraception. This method helps reduce the production cost of the IUD and has a wider range of applications.

[0009] Preferably, the two ends of the shape memory rib are bent to form limiting ears, the support spring is located between the two limiting ears, and the two ends of the support spring respectively abut against the two limiting ears on the side near the support spring.

[0010] By adopting the above technical solution, on the one hand, bending both ends of the shape memory rib to form limiting ears allows the ends of the shape memory rib to be concealed within the support spring, reducing the possibility of the shape memory rib ends puncturing or scratching people. On the other hand, confining the support spring between the two limiting ears reduces the possibility of the support spring detaching from the shape memory rib.

[0011] It is worth mentioning that when the required IUD is ring-shaped, the two limiting ears can be hooked together and squeezed, allowing the two limiting ears to enter the support spring, thus connecting the support spring end to end.

[0012] Preferably, both the support spring and the shape memory rib are made of stainless steel.

[0013] By adopting the above technical solution, both the support spring and the shape memory rib are made of stainless steel, reducing the possibility of the IUD causing harm to the human body.

[0014] Secondly, this application provides a processing device for supporting springs, which adopts the following technical solution:

[0015] A processing device for supporting springs includes a frame, on which a rotating shaft is rotatably mounted. One end of the rotating shaft is coaxially fixed with a winding shaft for winding and forming a supporting spring. The frame is provided with a driving component for driving the rotating shaft to rotate. The frame is also rotatably mounted with a pressing plate for pressing wire against the winding shaft. The axis of the pressing plate is parallel to the axis of the winding shaft, and the pressing plate is located on the side of the winding shaft closer to the rotating shaft.

[0016] Furthermore, the frame is also equipped with an unwinding component for unwinding the wire used to support the spring.

[0017] By adopting the above technical solution, in practical application, the unwinding component unwinds the wire for the support spring, and the driving component drives the rotating shaft and the winding shaft to rotate. Simultaneously, the pressure plate presses the wire against the winding shaft, thus the winding shaft winds the wire. Furthermore, as the wire is wound, the newly wound wire squeezes the already wound wire and pushes the wound portion towards the side of the winding shaft away from the rotating shaft. In this way, the production of the support spring is achieved.

[0018] Preferably, a guide shaft is coaxially fixed between the rotating shaft and the winding shaft, and the diameter of the guide shaft is larger than the diameter of the winding shaft.

[0019] By adopting the above technical solution, the guide shaft restricts the wire wound on the winding shaft, reducing the occurrence of the wire winding to one side of the rotating shaft, and helping to ensure that the support spring can exit the winding shaft normally.

[0020] Preferably, the edge of the guide shaft near one end of the winding shaft is chamfered to form a guide slope.

[0021] By adopting the above technical solution, when the wire deviates to one side of the guide shaft, it can be wound normally onto the winding shaft under the guidance of the guide slope, which helps to ensure the normal winding operation of the support spring.

[0022] Preferably, a shaping column is fixed on the side of the frame opposite to the rotating shaft. The axial direction of the shaping column is parallel to the axial direction of the winding shaft. A shaping hole is formed through the shaping column along its axis. The axis of the shaping hole is collinear with the axis of the winding shaft. The end of the shaping hole near the rotating shaft is chamfered to form a guide surface.

[0023] The frame is also equipped with a heating component for heating the shaped column.

[0024] By adopting the above technical solution, after the wire is wound on the winding shaft and detached from the pressure plate, the wire possesses a certain degree of self-recovery, causing the diameter of the support spring to increase. At this time, guided by the guide surface, the support spring is fed into the forming hole, and the heating component heats the forming column, which then conducts the heat to the support spring. The support spring is then constricted within the forming hole, allowing its diameter to reach the required diameter. This achieves the forming process of the support spring and ensures its production quality.

[0025] Preferably, the heating component includes two PTC heating plates, both of which are arc-shaped plates. The two PTC heating plates are respectively attached to opposite sides of the molding column in any radial direction, and the two PTC heating plates are adapted to the outer wall of the molding column.

[0026] By adopting the above technical solution, the molding column is heated by two arc-shaped PTC heating plates, which helps to ensure the uniformity of heating of the support spring by the heating component through the molding column.

[0027] Preferably, the frame has a support plate fixedly mounted on the side of the winding shaft away from the rotation shaft. The support plate is coaxial with the winding shaft and has a support hole coaxially opened on the support plate for a support spring to pass through. The frame has a mounting bracket movably mounted on the side of the support plate away from the rotation shaft. The mounting bracket is equipped with a cutting blade. The frame is also equipped with a power component for driving the movement of the mounting bracket.

[0028] By adopting the above technical solution, after a certain length of support spring passes through the support hole, the power component drives the mounting bracket to move, and the cutting blade cuts the support spring, thereby facilitating the production of the support spring.

[0029] Preferably, the unwinding component includes an unwinding wheel, the axis of which is parallel to the axis of the winding shaft, a support shaft is coaxially fixed on the unwinding wheel, the support shaft is rotatably connected to the frame, and a friction wheel is coaxially fixed on the support shaft.

[0030] A tensioning plate is fixed on one side of the frame located radially on the friction wheel. A tensioning screw is threaded onto the tensioning plate in a direction perpendicular to the axis of the friction wheel. Two tensioning screws are spaced apart on the tensioning plate. A friction belt is connected between the ends of the two tensioning screws near the friction wheel, and the friction belt passes around the friction wheel on the side away from the tensioning screw.

[0031] By adopting the above technical solution, in practical application, the operator can rotate the tension screw to make the friction belt press against the friction wheel, thereby tensioning the wire between the unwinding wheel and the winding shaft. This helps to ensure the tightness of the wire winding on the winding shaft and helps to ensure the normal production operation of the support spring. Attached Figure Description

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] This application discloses a processing equipment for an IUD and a supporting spring.

[0045] Reference Figure 1 and Figure 2 The IUD includes a support spring 1, with shape memory ribs 2 threaded inside the support spring 1. Both ends of the shape memory ribs 2 are bent to form limiting ears 21. The support spring 1 is located between the two limiting ears 21. The bent ends of the shape memory ribs 2 extend into the two ends of the support spring 1, respectively, and the two ends of the support spring 1 abut against the two limiting ears 21 on the side closest to the support spring 1. Copper wires 11 are spirally wound around the support spring 1. In this embodiment, one set of copper wires 11 is provided on each side of the support spring 1.

[0046] To reduce the harm of the IUD to the human body, both the support spring 1 and the shape memory rib 2 are made of medical-grade stainless steel.

[0047] Of course, in other embodiments, the shape memory rib 2 can also be made of one or more materials such as copper, gold, silver, and aluminum alloy.

[0048] The implementation principle of an IUD according to this application embodiment is as follows: In practical application, medical personnel can bend the shape memory rib 2 into the required shape according to the actual situation, and the support spring 1 will be supported by the shape memory rib 2 and consistent with the outline of the shape memory rib 2. At the same time, after the IUD is inserted into the uterus, the copper wire 11 can release copper ions to perform normal contraception.

[0049] See Figure 3 and Figure 4This embodiment also discloses a processing device for a support spring, including a frame 3. A rotating shaft 4 is rotatably mounted on the frame 3, and a winding shaft 41 is coaxially fixed to one end of the rotating shaft 4. A driving component 31 for driving the rotating shaft 4 to rotate is also provided on the frame 3. A pressing plate 5 for pressing wire against the winding shaft 41 is also rotatably mounted on the frame 3. The axis of the pressing plate 5 is parallel to the axis of the winding shaft 41, and the pressing plate 5 is located on the side of the winding shaft 41 closer to the rotating shaft 4. Furthermore, an unwinding component 6 for supplying wire to the winding shaft 41 is provided on the upper side of the frame 3, and a cutting component 7 is provided on the side of the frame 3 opposite to the rotating shaft 4. In practical application, the unwinding component 6 unwinds the wire coil and supplies wire to the winding shaft 41; then, the driving component 31 drives the rotating shaft 4 and the winding shaft 41 to rotate and wind the wire, thereby forming the support spring 1. As the winding shaft 41 winds the wire, the newly wound portion will push the already wound portion to the side away from the rotating shaft 4 and exit the winding shaft 41. The support spring 1 will then be cut by the cutting component 7 to form support springs 1 of the required length.

[0050] See Figure 5 and Figure 6 The rotating shaft 4 is horizontal, and a guide shaft 42 is coaxially fixed to one end of the rotating shaft 4 near the winding shaft 41. The winding shaft 41 is coaxially fixed to the guide shaft 42 at one end near the rotating shaft 4. The diameter of the guide shaft 42 is larger than the diameter of the winding shaft 41, and the edge of the guide shaft 42 near the winding shaft 41 is chamfered to form a guide bevel 421 (see...). Figure 7 The drive component 31 includes a geared motor 311, which is fixed to the frame 3 on the side of the rotating shaft 4 opposite to the winding shaft 41, and is coaxially fixed to the end of the rotating shaft 4 opposite to the winding shaft 41. Furthermore, the pressure plate 5 presses the wire against the side of the winding shaft 41 near the guide shaft 42.

[0051] See Figure 5 and Figure 8A support frame 8 is fixedly mounted on the upper side of the frame 3. A support shaft 81 is rotatably mounted on the upper side of the support frame 8, and the axis of the support shaft 81 is horizontal. A fixed plate 811 is fixed in the middle of the support shaft 81, and a fastening nut 812 is threadedly connected to the side of the support shaft 81 away from the support frame 8. The unwinding component 6 includes an unwinding wheel 61, which is sleeved on the support shaft 81. The unwinding wheel 61 is located between the fixed plate 811 and the fastening nut 812, and the fastening nut 812 presses the unwinding wheel 61 tightly onto the fixed plate 811. One end of the support shaft 81 away from the fastening nut 812 passes through the support frame 8, and a friction wheel 813 is coaxially fixed to the other end of the support shaft 81 away from the fastening nut 812. A tensioning plate 82 is fixed to the lower side of the friction wheel 813 on the support frame 8. A tensioning screw 821 is threaded onto the tensioning plate 82. The axis of the tensioning screw 821 is perpendicular to the axis of the friction wheel 813, and two tensioning screws 821 are spaced apart on the tensioning plate 82. One end of the tensioning screw 821 near the friction wheel 813 is connected to a tension spring 822. The other side of the tension spring 822 is connected to a friction belt 823 near the friction wheel 813, and the friction belt 823 wraps around the friction wheel 813 on the side away from the tensioning screw 821.

[0052] Meanwhile, several guide wheels 32 are installed on both the support frame 8 and the frame 3. All the guide wheels 32 work together to guide the wire unwound by the unwinding wheel 61 and supply the wire to the side of the winding shaft 41 near the guide shaft 42. In actual use, the wire is wound on the unwinding wheel 61 and guided to the winding shaft 41 by all the guide wheels 32. During the rotation of the winding shaft 41, the wire is pulled, thereby causing the unwinding wheel 61 to unwind. Furthermore, the operator can adjust the friction between the friction belt 823 and the friction wheel 813 by rotating the tension screw 821 as needed, and adjust the tightness of the wire on the winding shaft 41.

[0053] See Figure 9 and Figure 10A support frame 9 is fixed to the side of the winding shaft 41 away from the rotating shaft 4, located on the frame 3. A shaping column 91 is fixed on the support frame 9, and the axial direction of the shaping column 91 is parallel to the axial direction of the winding shaft 41. A shaping hole 911 is formed through the shaping column 91 along its axis. The axis of the shaping hole 911 is collinear with the axis of the winding shaft 41. The side of the winding shaft 41 away from the rotating shaft 4 passes into the shaping hole 911, and the end of the shaping hole 911 near the rotating shaft 4 is chamfered to form a guide surface 912. A heating element 92 is provided on the shaping column 91. The heating element 92 includes two PTC heating plates 921, both of which are arc-shaped plates. The two PTC heating plates 921 are respectively attached to opposite sides of the shaping column 91 in any radial direction, and the two PTC heating plates 921 are adapted to the outer wall of the shaping column 91. The support frame 9 is also fixed with a heat insulation cover 93, which covers two PTC heating plates 921.

[0054] In practical applications, the support spring 1, whose diameter increases due to its self-restoring property, will enter the shaping hole 911 under the guidance of the guide slope 421. Subsequently, the shaping column 91 is heated by two PTC heating plates 921, and the support spring 1 is heated by the shaping column 91. Afterward, as the support spring 1 continues to feed, under the constraint of the side wall of the shaping hole 911 and the winding shaft 41, the diameter of the support spring 1 tends to the required diameter, and the diameter of the support spring 1 will be fixed.

[0055] The shaping column 91 passes through the support frame 9 on the side facing away from the rotation axis 4. A support plate 94 is coaxially fixed to the end of the shaping column 91 facing away from the rotation axis 4. A support hole 941 is coaxially opened on the support plate 94, and the diameter of the support hole 941 is equal to that of the shaping hole 911. The cutting component 7 includes a mounting bracket 71 and a cutting blade 72. One end of the mounting bracket 71 is hinged to the support frame 9, and the hinge axis of the mounting bracket 71 is parallel to the axis of the support plate 94. The cutting blade 72 is disc-shaped and fixed to the mounting bracket 71 away from the hinge point between the mounting bracket 71 and the support frame 9. The axis of the cutting blade 72 is parallel to the axis of the support plate 94, and the cutting blade 72 rests against the side of the support plate 94 facing away from the shaping column 91. A power unit 95 is also provided on the support frame 9. The power unit 95 includes a cylinder 951, the cylinder body of which is hinged to the support frame 9, and the end of the piston rod of the cylinder 951 is hinged to the middle of the mounting bracket 71. A support plate 711 is also fixed on the side of the mounting bracket 71 near the cutting blade 72, and the support plate 711 is located below the support hole 941. When the cutting blade 72 is restricted, the cutting blade 72 and the support plate 711 are located on the upper and lower sides of the support hole 941, respectively. When the support spring 1 is cut, the cylinder 951 drives the mounting bracket 71 to rotate, and the cutting blade 72 cuts the support spring 1. During this process, the support plate 711 supports the support spring 1, reducing the possibility of the support spring 1 bending under the cut and reducing the possibility of large deformation at the end of the support spring 1.

[0056] The implementation principle of the support spring 1 processing equipment in this application embodiment is as follows: In actual use, the wire is wound on the unwinding wheel 61, and the wire is guided to the winding shaft 41 by all the guide wheels 32, and the wire is passed between the winding shaft 41 and the pressure plate 5; then, the geared motor 311 drives the rotating shaft 4 and the winding shaft 41 to rotate and wind the wire, while pulling the wire so that the unwinding wheel 61 unwinds; during this process, as the winding shaft 41 winds the wire, the newly wound part will push the already wound part to move away from the rotating shaft 4.

[0057] As the support spring 1 is fed, it enters the shaping hole 911 under the guidance of the guide ramp 421. Then, the shaping column 91 is heated by two PTC heating plates 921, and the support spring 1 is heated by the shaping column 91. After that, as the support spring 1 continues to be fed, the diameter of the support spring 1 tends to the required diameter under the constraint of the side wall of the shaping hole 911 and the winding shaft 41. Finally, the mounting bracket 71 is driven to swing by the cylinder 951, and the support spring 1 is cut off by the cutting blade 72.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
