Description

Technical Field

[0001] The utility model relates to the technical field of spring coiling machines, in particular to a spring coiling machine for producing spring rings. Background Art

[0002] Coils are medical devices used to treat aneurysms. In 1991, Guglielmi et al. first reported GDC embolization for the treatment of intracranial aneurysms. The distal end of the GDC is a platinum coil, which is connected to a stainless steel guide wire and can be directly delivered into the aneurysm. When direct current is applied, the coil attracts negatively charged blood components such as red blood cells, white blood cells, and platelets to undergo electrocoagulation, forming a thrombus in the aneurysm. At the same time, the part of the coil connected to the stainless steel guide wire is dissolved by electrolysis, and the coil is released and retained in the aneurysm. The GDC coil is extremely soft and has good compliance when advancing and retreating in the aneurysm. If the placement is not satisfactory, it can be adjusted, and occlusion of the tumor-bearing artery is not likely to occur.

[0003] In the process of spring coil production, a spring coiling machine is needed to shape the raw material. One end of the raw material is inserted into the coiling block. While the coiling block rotates, it moves horizontally to shape the raw material into a spring coil. This has the following disadvantages:

[0004] 1. The rotation and horizontal movement of the coil spring block need to be driven by two power components, and the equipment investment cost is relatively high;

[0005] 2. The formed spring coil is not easy to remove from the coil block, and manual unloading is required, which results in low production efficiency. Utility Model Content

[0032] Embodiment 1

[0033] Combined with Figure 1-3A sleeve 3 is provided on the vertical plate 2, and a coil spring block 4 is connected to the internal thread of the sleeve 3. A plug-in hole 5 is provided on the side of the coil spring block 4. A driving component is provided on the back of the vertical plate 2. The driving component drives the coil spring block 4 to rotate and moves in a direction perpendicular to the vertical plate 2; the driving component includes a mounting plate 7 and a motor 8. A motor 8 is provided on the upper end surface of the mounting plate 7, and the output end of the motor 8 is connected to the coil spring block 4. A limiting rod 9 is provided on the back of the vertical plate 2, and the mounting plate 7 is slidably connected to the limiting rod 9.

[0034] When in use, the feeding mechanism transports the raw materials and inserts one end of the raw materials into the plug hole 5. At this time, the motor 8 rotates, and the motor 8 drives the coil spring block 4 to rotate. While the coil spring block 4 rotates, the coil spring block 4 moves horizontally in a direction perpendicular to the vertical plate 2 through the sleeve 3 threadedly connected to it. During the movement of the coil spring block 4, the mounting plate 7 moves along the limiting rod 9, thereby realizing a single motor 8 to drive the coil spring block 4 to rotate and move horizontally.

[0035] Combined with Figure 1-4 A pushing assembly is provided on the mounting plate 7, and the pushing assembly pushes the formed spring coil off the coil spring block 4. The pushing assembly includes a pushing ring 10, a transmission rod 11 and an electromagnet 12. A vertical plate 13 is provided on the side of the mounting plate 7, and a connecting plate 14 is provided on the side of the vertical plate 13 opposite to the motor 8. An electromagnet 12 is provided on the front of the connecting plate 14, and a transmission rod 11 is provided on the front side of the electromagnet 12. The transmission rod 11 is slidably connected to the vertical plate 2, and a magnetic suction piece 15 is provided at the rear end of the transmission rod 11. A tension spring 16 is provided between the magnetic suction piece 15 and the vertical plate 2, and a connecting piece 17 is provided at the front end of the transmission rod 11. The push ring 10 is sleeved on the outside of the coil spring block 4, and the connecting piece 17 is connected to the push ring 10.

[0036] After the spring forming is completed, the electromagnet 12 is powered off and no longer attracts the magnetic sheet 15. The magnetic sheet 15 moves forward under the action of the tension spring 16, driving the transmission rod 11 to move forward. The transmission rod 11 drives the push ring 10 to move forward through the connecting piece 17, pushing out the formed spring coil. One end of the spring coil embedded in the coil spring block 4 is pushed out from the slot 6, realizing automatic unloading of the formed spring coil.

[0039] On the basis of the first embodiment, the distance measuring sensor 18 detects the movement distance of the mounting plate 7, thereby controlling the movement distance of the coil spring block 4, and the two limiting rods 9 stably limit and guide the mounting plate.

[0040] The utility model and its implementation methods are described, and such description is not restrictive. The drawings are only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and implementation method similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
