Description

Technical Field

[0001] This invention relates to the field of spring coil release equipment technology, specifically a convenient mechanical release mechanism for spring coils. Background Technology

[0002] Coils are medical devices used to treat aneurysms. During treatment, coils are inserted into the aneurysm to fill it, thereby preventing blood from flowing into the aneurysm and thus preventing the aneurysm from rupturing.

[0003] In the prior art, when using spring coil release, the spring coil needs to be smoothly inserted into the aneurysm via a push rod, and then the spring coil is released and separated. Before release, the spring coil needs to be connected to the push rod via a connecting mechanism. However, when pulling the connecting mechanism to release the spring coil, the elastic force of the spring and the force of the clamping plate conflict with each other, which can easily cause it to get stuck, resulting in the failure of spring coil release. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient spring coil release device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a convenient spring coil release device, including a feeding rod, a release spring fixedly connected to the end of the feeding rod, a distal connector provided at the end of the release spring away from the feeding rod, and a spring coil fixedly connected to the distal connector at the end away from the release spring; and further comprising: A pulling mechanism, the pulling mechanism including a push plate, the surface of which is fixedly connected to a driven rod; A release mechanism, the release mechanism including a proximal connector, the end of the proximal connector being rotatably connected to a locking plate; An anti-jamming mechanism, comprising a telescopic elastic rod, the end of which is fixedly connected to a force-bearing inclined plate.

[0006] Furthermore, the inner wall of the feed rod is provided with a balance groove, and the end of the release spring away from the feed rod contacts the end of the distal connector.

[0007] Furthermore, the pulling mechanism also includes a grip plate, the surface of which is fixedly connected to a compression plate, and the inner wall of the balance groove is slidably connected to a balance slide plate.

[0008] Furthermore, one end of the extrusion plate near the push plate penetrates the surface of the feeding rod and is fixedly connected to the end of the push plate. There are four push plates, which are divided into two groups of two each, and the four extrusion plates are arranged symmetrically.

[0009] Furthermore, the release mechanism also includes a release screw, the end of which is fixedly connected to a support plate, and the top of the clamping plate is hinged to a pull rod.

[0010] Furthermore, the end of the driven rod away from the push plate is fixedly connected to the surface of the release screw, the inner wall of the balance slide away from the balance groove is fixedly connected to the surface of the release screw, the end of the proximal connector is fixedly connected to the end of the feed rod, the end of the pull rod away from the clamping plate is hinged to the support plate, and the surface of the clamping plate is in contact with the end of the distal connector.

[0011] Furthermore, the anti-jamming mechanism also includes a U-shaped plate, a curved plate is fixedly connected to the end of the support plate away from the release screw, and a pressing rod is fixedly connected to the surface of the proximal connector.

[0012] Furthermore, the end of the telescopic elastic rod away from the force-bearing inclined plate is fixedly connected to the inner wall of the near-end connector, the end of the U-shaped plate near the force-bearing inclined plate passes through the surface of the far-end connector and is fixedly connected to the surface of the force-bearing inclined plate, and the end of the curved plate is in contact with the surface of the force-bearing inclined plate.

[0013] The present invention has the following beneficial effects: This invention, through the setting of a pulling mechanism, firstly involves the operator gripping and squeezing the gripping plate. When the gripping plate is squeezed, it moves towards each other. As the gripping plate moves, it pushes the squeezing plate towards each other. As the squeezing plate moves, it pushes the end of the push plate towards each other. The other end of the push plate pushes the driven rod towards the end of the delivery rod. When the driven rod moves, it drives the release screw towards the end of the delivery rod. When the release screw moves, it drives the balance slide plate to slide on the inner wall of the balance groove towards the end of the delivery rod, thereby keeping the release screw balanced during movement. The gripping plate also makes it convenient for the operator to operate and improves practicality.

[0014] This invention provides a release mechanism. When the release screw moves, it pulls the support plate toward the end of the feed rod. When the support plate moves, it pulls the end of the pull rod toward the feed rod. Meanwhile, the other end of the pull rod pulls the locking plate toward each other. At this time, the locking plate separates from the end of the distal connector, thereby achieving the purpose of releasing the distal connector.

[0015] This invention employs an anti-jamming mechanism. When the support plate moves, it causes the curved plate to move towards the release screw. The movement of the curved plate pushes the force-bearing inclined plate towards the release screw. The movement of the force-bearing inclined plate then causes the telescopic elastic rod to move towards the release screw. The movement of the telescopic elastic rod, in turn, causes the distal connecting piece to move towards the release screw. The movement of the distal connecting piece compresses the release spring, causing it to contract towards the release screw, thus storing force. Simultaneously, the movement of the force-bearing inclined plate also drives the U-shaped plate. As the inclined plate moves towards the release screw, it experiences compressive force when its surface contacts the end of the compression rod. This compressive force pushes the telescopic elastic rod to retract away from each other. The movement of the inclined plate further pushes the U-shaped plate away from each other, causing the end of the curved plate to separate from the surface of the inclined plate. Simultaneously, the locking plate returns to its original position. At this point, the distal connector is no longer restrained, and the release spring's elasticity ejects the distal connector from the spring coil, thus preventing the spring coil from getting stuck during release and improving efficiency.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 8 As shown, the present invention is a convenient spring coil release device, including a feeding rod 1, a release spring 2 fixedly connected to the end of the feeding rod 1, a distal connector 3 provided at the end of the release spring 2 away from the feeding rod 1, and a spring coil 4 fixedly connected at the end of the distal connector 3 away from the release spring 2, and also includes; Pulling mechanism 10 includes push plate 13. When the pressing plate 12 moves, it pushes the end of the push plate 13 to move closer to each other, while the other end of the push plate 13 pushes the driven rod 14 to move towards the end of the feeding rod 1. The driven rod 14 is fixedly connected to the surface of the push plate 13. When the driven rod 14 moves, it drives the release screw 31 to move towards the end of the feeding rod 1. The release mechanism 30 includes a proximal connector 33, with a locking plate 34 rotatably connected to the end of the proximal connector 33. When the support plate 32 moves, it pulls the end of the pull rod 35 toward the direction of the feed rod 1, while the other end of the pull rod 35 pulls the locking plate 34 toward each other. At this time, the locking plate 34 will separate from the end of the distal connector 3, thereby releasing the distal connector 3. The anti-jamming mechanism 50 includes a telescopic elastic rod 51. When the telescopic elastic rod 51 moves, it will drive the distal connector 3 to move in the direction of the release screw 31. When the force-bearing inclined plate 52 moves, it will drive the telescopic elastic rod 51 to move in the direction of the release screw 31. The end of the telescopic elastic rod 51 is fixedly connected to the force-bearing inclined plate 52. When the curved plate 54 moves, it will push the force-bearing inclined plate 52 to move in the direction of the release screw 31.

[0022] The inner wall of the feed rod 1 is provided with a balance groove, and the end of the release spring 2 away from the feed rod 1 contacts the end of the distal connector 3.

[0023] The pulling mechanism 10 also includes a grip plate 11. First, the operator grips the grip plate 11 and squeezes it. When the grip plate 11 is squeezed, it moves towards each other. A pressing plate 12 is fixedly connected to the surface of the grip plate 11. When the grip plate 11 moves, it pushes the pressing plate 12 to move towards each other. A balance slide plate 15 is slidably connected to the inner wall of the balance slide groove. When the release screw 31 moves, it drives the balance slide plate 15 to slide on the inner wall of the balance slide groove towards the end of the feed rod 1, so that the release screw 31 remains balanced when moving. The grip plate 11 also makes it easier for the operator to operate and improves practicality.

[0024] One end of the extrusion plate 12 near the push plate 13 passes through the surface of the feed rod 1 and is fixedly connected to the end of the push plate 13. There are four push plates 13, which are divided into two groups of two each, and the four extrusion plates 12 are arranged symmetrically.

[0025] The release mechanism 30 also includes a release screw 31. When the release screw 31 moves, it pulls the support plate 32 to move toward the end of the feed rod 1. The end of the release screw 31 is fixedly connected to the support plate 32. The top of the clamping plate 34 is hinged to the pull rod 35. At this time, the support plate 32 will separate from the clamping plate 34.

[0026] The end of the driven rod 14 away from the push plate 13 is fixedly connected to the surface of the release screw 31. The balance slide plate 15 away from the inner wall of the balance groove is fixedly connected to the surface of the release screw 31. The end of the near-end connector 33 is fixedly connected to the end of the feed rod 1. The end of the pull plate 35 away from the clamping plate (34) is hinged to the support plate 32. The surface of the clamping plate 34 is in contact with the end of the far-end connector 3.

[0027] The anti-jamming mechanism 50 also includes a U-shaped plate 53. When the force-bearing inclined plate 52 moves, it will push the U-shaped plate 53 to move away from each other. The end of the support plate 32 away from the release screw 31 is fixedly connected to a curved plate 54. When the support plate 32 moves, it will drive the curved plate 54 to move towards the release screw 31. At this time, the end of the curved plate 54 separates from the surface of the force-bearing inclined plate 52. The surface of the near end connector 33 is fixedly connected to a pressing rod 55. When the surface of the force-bearing inclined plate 52 contacts the end of the pressing rod 55, it will be subjected to pressing force.

[0028] The end of the telescopic elastic rod 51 away from the force-bearing inclined plate 52 is fixedly connected to the inner wall of the near-end connector 33. When the force-bearing inclined plate 52 is subjected to compressive force, it will push the telescopic elastic rod 51 to contract in a direction away from each other. The end of the U-shaped plate 53 near the force-bearing inclined plate 52 passes through the surface of the far-end connector 3. When the force-bearing inclined plate 52 moves, it will drive the U-shaped plate 53 to move in the direction of the release screw 31 and be fixedly connected to the surface of the force-bearing inclined plate 52. The end of the curved plate 54 contacts the surface of the force-bearing inclined plate 52. At the same time, the locking plate 34 has been reset to its original position. At this time, the far-end connector 3 has no binding force, and the far-end connector 3 and the spring ring 4 are ejected by the elastic force of the release spring 2, thereby avoiding the phenomenon of the spring ring 4 getting stuck when releasing and improving the efficiency of use.

[0029] In use, the operator first grasps and squeezes the grip plate 11. When squeezed, the grip plate 11 moves closer together. This movement pushes the squeezing plate 12 closer together, which in turn pushes the end of the push plate 13 closer together. The other end of the push plate 13 pushes the driven rod 14 towards the end of the feed rod 1. The movement of the driven rod 14 causes the release screw 31 to move towards the end of the feed rod 1. The movement of the release screw 31 causes the balance slide plate 15 to slide along the inner wall of the balance groove towards the end of the feed rod 1, thus maintaining balance during movement. The grip plate 11 also facilitates operation and improves practicality. The movement of the release screw 31 pulls the support plate 32 towards the end of the feed rod 1, which in turn pulls the end of the pull rod 35 towards the feed rod 1. The other end of the lever 35 pulls the locking plate 34 to move closer together. At this time, the locking plate 34 separates from the end of the distal connector 3, thereby releasing the distal connector 3. When the support plate 32 moves, it drives the curved plate 54 to move towards the release screw 31. When the curved plate 54 moves, it pushes the force-bearing inclined plate 52 to move towards the release screw 31. When the force-bearing inclined plate 52 moves, it drives the telescopic elastic rod 51 to move towards the release screw 31. When the telescopic elastic rod 51 moves, it drives the distal connector 3 to move towards the release screw 31. When the distal connector 3 moves, it squeezes the release spring 2 to move towards the release screw 31, causing the release spring 2 to move. The release spring retracts towards the release screw 31, thus storing force. When the force-bearing inclined plate 52 moves, it will drive the U-shaped plate 53 to move towards the release screw 31. When the surface of the force-bearing inclined plate 52 contacts the end of the pressing rod 55, it will be subjected to pressing force. When the force-bearing inclined plate 52 is subjected to pressing force, it will push the telescopic elastic rod 51 to retract in a direction away from each other. When the force-bearing inclined plate 52 moves, it will push the U-shaped plate 53 to move in a direction away from each other. At this time, the end of the curved plate 54 separates from the surface of the force-bearing inclined plate 52, and the locking plate 34 has been reset to its original position. At this time, the distal connector 3 has no binding force, and the distal connector 3 and the spring ring 4 are ejected by the elastic force of the release spring 2.
