Description

Technical Field

[0001] The invention relates to the technical field of guidewire recovery, and in particular to a fully automatic recovery device for discarded guidewires for neurointervention. Background Art

[0002] Discarded neurointerventional guidewires refer to guidewires used during neurointerventional surgeries. These guidewires need to be recycled and processed after completing their mission. The medical industry usually uses special equipment to recycle and process these discarded guidewires. Among them, the fully automatic recycling device for discarded neurointerventional guidewires can efficiently and accurately recycle used guidewires. Through a series of carefully designed mechanical structures and control systems, the device realizes the functions of automatic loading, positioning, winding and collection of guidewires, which greatly improves work efficiency and accuracy and reduces operating difficulty and cost.

[0003] When recycling existing discarded guide wires, it is necessary to first place one end of the guide wire into the plug-in hole, and then use the active roller and the auxiliary roller to drive the guide wire to move into the device. A winding rod is rotatably provided at the bottom of the device to wind the guide wire onto one or more winding rods. However, after the guide wire is placed in the plug-in hole, it is not enough to only use the active roller and the auxiliary roller to drive the guide wire to be transported. If the medical staff does not sort out the guide wire after use and then recycles it, the guide wire as a whole is in a messy state, and the remaining parts of the guide wire are piled up together. It is difficult to pull the guide wire by relying on the power provided by the active roller and the auxiliary roller, which will affect the recovery progress of the guide wire.

The rotation of the roller 10 can drive the guide wire to move into the fixed cylinder 5 until it reaches the turntable 2. The turntable 2 is in a rotating state at this time, which will drive the winding rod 3 to rotate, so that the guide wire is wound around the outside of one or more winding rods 3. If the guide wire is not sorted and placed in a pile in the receiving bin 4, it is difficult to ensure that the guide wire is in a moving state only by the power provided by the two rollers 10. Therefore, the conveying assembly 8 provided on the circular plate 6 can drive the guide wire to move intermittently in a direction close to the feed hole 71. In addition, the sliding block 7 can also move left and right along the sliding groove 61 to drive the fixed frame 9 to move, so that the guide wire in the fixed cylinder 5 also moves accordingly, which is convenient for evenly winding the guide wire to the outside of the winding rod 3 and reasonably using the space of the winding rod 3. The fixed frame 9 provides support for the roller 10, and the base 1 provides support for the fixed cylinder 5.

[0032] See also Figure 1 and Figure 4-Figure 6As shown, in the present embodiment, preferably, the conveying assembly 8 comprises a fixed block 81, a movable groove 82 is provided at the center of the fixed block 81, a movable block 83 is slidably arranged in the movable groove 82, a cylinder 84 is rotatably arranged in the movable block 83, a sleeve 85 is movably arranged in the cylinder 84, a plurality of circular holes 86 are provided in an annular array at one end of the sleeve 85 close to the feed hole 71, a limiting ball 87 is movably arranged in the circular hole 86, and the sleeve 85 is fixedly connected to the movable block 83; one end of the guide wire passes through the sleeve 85 and the feed hole 71 and enters the fixed cylinder 5. In the initial state, a length of guide wire needs to be reserved between the feed hole 71 and the sleeve 85, that is, the guide wire between the feed hole 71 and the sleeve 85 cannot be too tight, and the motors of the roller 10 and the turntable 2 are started. When the movable block 83 moves along the fixed When the movable groove 82 opened in the block 81 moves toward the direction close to the feed hole 71, the movement of the movable block 83 will drive the cylinder 84 and the sleeve 85 to move synchronously. During the movement, the limiting ball 87 is squeezed inward along the circular hole 86. The limiting ball 87 is made of elastic material. When the limiting ball 87 is squeezed, it will move toward the circular hole 86 to clamp the guide wire in the sleeve 85, and can pull the guide wire to move toward the feed hole 71 along with the movement of the movable block 83. Even if the guide wire is in a state of disorderly accumulation, it can ensure that the guide wire moves smoothly toward the feed hole 71. Subsequently, the movable block 83 does not squeeze the limiting ball 87 during the process of moving back to the initial position (see below for the specific implementation process), so that the guide wire will not move in the opposite direction with the movable block 83, so that a part of the guide wire is pulled to the vicinity of the feed hole 71.

[0033] See also Figure 4-Figure 6As shown, in this embodiment, preferably, a rotating cylinder 11 is provided between the sleeve 85 and the cylinder 84, the rotating cylinder 11 is movably embedded in the cylinder 84, the rotating cylinder 11 is rotatably connected relative to the sleeve 85, a rotating ring 12 is fixedly provided on the rotating cylinder 11 near the limiting ball 87, a plurality of protrusions 13 are provided in an annular array on the rotating ring 12, a notch 14 is provided between two adjacent protrusions 13, and the protrusions 13 are movably abutted against the limiting ball 87; when the moving block 83, the sleeve 85, the cylinder 84 and the rotating cylinder 11 move synchronously toward the direction close to the feeding hole 71, the rotating cylinder 11 rotates relative to the sleeve 85, and the rotating cylinder 11 rotates relative to the sleeve 85. The rotating cylinder 11, the rotation of the rotating cylinder 11 will drive the rotating ring 12 and the protrusion 13 to rotate. During the rotation of the protrusion 13, it will abut against the limiting ball 87, so that the limiting ball 87 moves toward the inside of the circular hole 86 to clamp the guide wire and then pull the guide wire to move. The partial area of ​​the protrusion 13 is limited. When the protrusion 13 rotates to no longer abut against the limiting ball 87, the limiting ball 87 is located in the notch 14. At this time, the limiting ball 87 will not be squeezed and the clamping of the guide wire will be released. At this time, the moving block 83 moves in the opposite direction to the initial position and the rotating cylinder 11 is not rotated. The guide wire will not return with the moving block 83, so that the guide wire can move to the vicinity of the feed hole 71.

[0034] See also Figure 7-Figure 9 As shown, in this embodiment, preferably, a first gear 15 is movably embedded in the outer side of the rotating cylinder 11, a ring 16 is fixedly provided at one end of the first gear 15, a plurality of sawtooth grooves 161 are provided in an annular array on the outer side of the ring 16, a sawtooth block 17 is movably engaged in the sawtooth groove 161, and a limit spring 18 is fixedly provided between the sawtooth block 17 and the rotating cylinder 11; when the moving block 83, the sleeve 85, the cylinder 84 and the rotating cylinder 11 move synchronously toward the direction close to the feed hole 71, the first gear 15 and the ring 16 are rotated, and when the sawtooth groove 161 rotates in this direction, it is in a locked state with the sawtooth block 17. When the movable block 83 moves in the reverse direction, the first gear 15 is rotated in the reverse direction, and the first gear 15 drives the ring 16 to rotate in the reverse direction. When rotating in this direction, the sawtooth groove 161 and the sawtooth block 17 are not in a clamping state. The limiting spring 18 will be compressed during the rotation of the ring 16, and the rotation of the ring 16 will not drive the rotating cylinder 11 to rotate. At this time, the limiting ball 87 is located in the notch 14, and the limiting ball 87 does not clamp the guide wire. Therefore, the reverse movement of the movable block 83 will not drive the guide wire to move, thereby avoiding reverse delivery of the guide wire.

[0035] See also Figure 5-Figure 7As shown, in this embodiment, preferably, an internal gear 19 is fixedly provided on the inner wall of the cylinder 84, and the internal gear 19 is meshed with the first gear 15 for transmission. A transverse groove 831 is provided on one side of the moving block 83, and a limiting rod 20 is fixedly provided on the side of the fixed block 81 close to the transverse groove 831, and the limiting rod 20 is slidably connected with the transverse groove 831. A curved groove 841 is provided on the outer side of the cylinder 84, and the limiting rod 20 is slidably fitted with the curved groove 841; when the moving block 83, the sleeve 85, the cylinder 84 and the rotating cylinder 11 move synchronously toward the direction close to the feed hole 71, the curved groove 841 will contact the limiting rod 20 provided in the transverse groove 831, thereby driving the cylinder 84 to rotate. The rotation of the cylinder 84 will drive the internal gear 19 to rotate, thereby driving the first gear 15 and the ring 16 to rotate. When rotating in this direction, the serrated groove 161 and the serrated block 17 are clamped, and the rotating cylinder 11 will rotate. The rotating cylinder 11 can drive the rotating ring 12 and the protrusion 13 to rotate so that the limiting ball 87 clamps the guide wire until the notch 14 coincides with the limiting ball 87 and then stops rotating, and then moves the moving block 83 in the opposite direction. Under the action of the limiting rod 20, the cylinder 84 rotates in the opposite direction so that the first gear 15 and the ring 16 also rotate in the opposite direction. At this time, the rotating cylinder 11 rotates asynchronously, and the limiting ball 87 does not clamp the guide wire, so the guide wire will continue to stay near the feed hole 71, and the above process is repeated to complete the auxiliary transportation of the guide wire.

[0036] See also Figure 10-11As shown, in this embodiment, preferably, a notch 811 is provided on one side of the fixed block 81, a movable frame 21 is movably provided in the notch 811, a movable cylinder 22 is provided on one side of the movable frame 21, a movable plate 23 is fixedly provided on the movable cylinder 22 near the notch 811, the movable plate 23 is slidably connected to the movable frame 21 and a plurality of positioning springs 24 are fixedly connected to the movable frame 21, the fixed block 81 is located above the notch 811 and has a positioning groove 812, the movable cylinder 22 is fixedly provided with a movable plate 23, and the movable plate 23 is slidably connected to the movable frame 21 and a plurality of positioning springs 24 are fixedly connected to the movable frame 21. A positioning rod 25 is fixedly provided on the side, and the positioning rod 25 is slidably connected to the positioning groove 812; one end of the guide wire first passes through the moving cylinder 22 and then passes through the sleeve 85 and the feeding hole 71 to enter the fixed cylinder 5. When the moving block 83 moves in the direction close to the feeding hole 71, it will pull a part of the guide wire to move to the vicinity of the feeding hole 71. At the same time, the moving frame 21 moves in the opposite direction along the notch 811. The movement of the moving frame 21 will drive the moving cylinder 22 to move in the opposite direction. The movement of the moving cylinder 22 can straighten the subsequent guide wire part to avoid entanglement. The phenomenon of winding is convenient for the subsequent delivery of the guide wire. The movement of the moving cylinder 22 will also drive the moving plate 23 and the positioning rod 25 to move synchronously. The positioning rod 25 moves along the positioning groove 812. The positioning groove 812 is composed of a plurality of inclined grooves. Therefore, the positioning rod 25 moves back and forth up and down during the movement, thereby driving the moving cylinder 22 and the moving plate 23 to move back and forth up and down. The upward movement of the moving plate 23 will stretch the positioning spring 24, and the downward movement of the positioning plate will make the positioning spring 24 return to its initial state. With the help of the characteristics of the spring, the moving cylinder 22 will shake during the reverse movement. The shaking of the moving cylinder 22 can generate a slight vibration force, so that the guide wire maintains a certain tension and stability during the delivery process. This vibration force helps to eliminate the stress and deformation inside the guide wire, thereby reducing the occurrence of curling. In addition, the shaking of the moving cylinder 22 can also promote the relative movement between the guide wire and the moving cylinder 22, so that the guide wire can pass through the moving cylinder 22 more easily and enter the next processing link. This relative movement can reduce the friction and wear between the guide wire and the moving cylinder 22, thereby extending the service life of the guide wire.

When rotating in this direction, the sawtooth groove 161 and the sawtooth block 17 are clamped, and the rotating cylinder 11 will rotate. The rotating cylinder 11 can drive the rotating ring 12 and the protrusion 13 to rotate so that the limiting ball 87 clamps the guide wire until the notch 14 coincides with the limiting ball 87 and stops rotating. Then the moving block 83 is moved in the opposite direction. Under the action of the limiting rod 20, the cylinder 84 rotates in the opposite direction. The movement causes the first gear 15 and the ring 16 to rotate in the opposite direction. At this time, the rotating cylinder 11 rotates asynchronously, and the limiting ball 87 does not clamp the guide wire, so the guide wire will continue to stay near the feeding hole 71. The above process is repeated to complete the auxiliary transportation of the guide wire. At the same time, when the moving block 83 moves in the direction close to the feeding hole 71, it will drive the first rack 26 to move, thereby driving the second gear 28 to rotate and then causing the second rack 27 to move in the direction of the slot 811. The movement of the second rack 27 will drive the moving frame 21 to move in the opposite direction. The movement of the moving cylinder 22 can straighten the subsequent guide wire part to avoid entanglement, which is convenient for the subsequent transportation of the guide wire. The movement of the moving cylinder 22 will also drive the moving plate 23 and the positioning rod 25 to move synchronously. The rod 25 moves along the positioning groove 812, and the positioning groove 812 is composed of a plurality of inclined grooves. Therefore, the positioning rod 25 moves back and forth up and down during the movement, thereby driving the moving cylinder 22 and the moving plate 23 to move back and forth up and down. The upward movement of the moving plate 23 will stretch the positioning spring 24, and the downward movement of the positioning plate will make the positioning spring 24 return to the initial state. With the help of the characteristics of the spring, the moving cylinder 22 will shake during the reverse movement. The shaking of the moving cylinder 22 can generate a slight vibration force, so that the guide wire maintains a certain tension and stability during the transportation process. This vibration force helps to eliminate the stress and deformation inside the guide wire, thereby reducing the occurrence of curling. In addition, the shaking of the moving cylinder 22 can also promote the relative movement between the guide wire and the moving cylinder 22.This makes it easier for the guide wire to pass through the moving cylinder 22 and enter the next processing link. This relative movement can reduce the friction and wear between the guide wire and the moving cylinder 22, thereby extending the service life of the guide wire.
