Description

Technical Field

[0001] This utility model belongs to the field of guide wire bending processing, and specifically relates to a guide wire J-bending shaping device that can be heated and bent. Background Technology

[0002] J-shaped guidewires are widely used medical devices in the medical field. Their most distinctive feature is the J-shaped bend at the tip, a unique design that provides better maneuverability and adaptability during operation. In traditional J-shaped guidewire manufacturing, the bending of the tip is often done manually, which is inefficient, costly, and results in inconsistent product quality.

[0003] To address this problem, a prior patent provides a guide wire bending device (application number CN202120325668.9). The device comprises a head fixing mechanism for fixing the guide wire tip, a pulling mechanism for fixing the guide wire and cooperating with the head fixing mechanism to tighten the guide wire, and a bending mechanism for bending the guide wire tip. The pulling mechanism has a pulling fixing position for fixing the guide wire, the head fixing mechanism has a head fixing position for fixing the guide wire tip, and the bending mechanism has a bending position for abutting against the guide wire to cooperate with the pulling mechanism and the head fixing mechanism to bend the guide wire tip. The shape formed by the head fixing position, bending position, and pulling fixing position is triangular. This prior patent provides a guide wire bending device that can automatically bend the guide wire tip, significantly improving efficiency and reducing labor costs compared to traditional manual bending operations.

[0004] However, this type of bending device is mainly used for bending guide wires with stainless steel core wires. It cannot bend and shape guide wires with nickel-titanium alloy core wires, so its application range is relatively small. Utility Model Content

[0060] A rotary drive assembly 4 is used to drive the rotary seat 1 to rotate, and the rotary drive assembly 4 is driven to connect to the rotary seat 1.

[0061] Heating component 8 is used for heating, and heating component 8 corresponds to winding guide wire position 21.

[0062] In this embodiment, the heating assembly 8 includes a hot air heater 81, which includes a blower pipe 82 for blowing out hot air. The blower pipe 82 corresponds to the winding wire position 21. The hot air heater 81 can be an existing hot air box. By connecting to an external heater, the air pressure and airflow of the hot air blown out from the blower pipe 82 can be controlled after the hot air is introduced by the external heater. It is known that the external heater can heat the air through a heating wire. The hot air heater contains a power regulator, a temperature controller, a compressed air solenoid valve, a compressed air pressure regulating valve, a compressed air flow regulating valve, etc., to control the air pressure and airflow of the hot air blown out from the blower pipe 82.

[0064] In this embodiment, the blower tube drive assembly includes a blower tube lifting drive cylinder 83, a blower tube translation drive cylinder 84, and a blower tube bracket 85. The blower tube lifting drive cylinder 83 is fixedly mounted on the blower tube bracket 85, and the blower tube lifting drive cylinder 83 is drivenly connected to the blower tube translation drive cylinder 84. The blower tube translation drive cylinder 84 is drivenly connected to the blower tube 82.

[0065] In this embodiment, the device further includes a frame 9, on which a worktable 91 is provided, and a mounting cavity 92 is provided inside the frame 9. The rotary drive assembly 4 is fixed to the frame 9, and the wire winding assembly 2 extends through the worktable 91 so that the wire winding position 21 is exposed outside the worktable 91. The heating assembly 8 is disposed in the mounting cavity 92, located below the wire winding position 21, and the hot air heater 81 and the blower tube bracket 85 of the heating assembly 8 are both connected to the frame.

[0066] In this embodiment, the front clamping component 3 includes:

[0067] First gripper 31;

[0068] Second gripper 32;

[0069] A front-end gripper cylinder 33 is used to control the clamping or disengaging of the first gripper 31 and the second gripper 32. Both the first gripper 31 and the second gripper 32 are drivenly connected to the front-end gripper cylinder 33. The front-end gripper cylinder 33 can control the first gripper 31 and the second gripper 32 to clamp together to hold the front end of the guide wire; it can also control the first gripper 31 and the second gripper 32 to disengage to release the front end of the guide wire.

[0070] In this embodiment, the first gripper 31 has a clamping groove 311 adapted to the tip of the guide wire on the side near the second gripper 32, and the second gripper 32 has a clamping plane 321 on the side near the first gripper. The clamping screen corresponds to the clamping groove 311. After the tip of the guide wire extends into the clamping groove 311, the first gripper 31 and the second gripper 32 clamp together, so that the clamping plane 321 presses on the tip of the guide wire. Through the cooperation of the clamping groove 311 and the clamping plane 321, the tip of the guide wire is clamped and fixed more stably.

[0071] In this embodiment, a first guide opening 312 is provided at one end of the clamping groove 311 near the winding guide wire position 21. The width of the clamping guide opening gradually decreases from one end near the winding guide wire position 21 to the other end. The first guide opening 312 can guide the tip of the guide wire to extend into the clamping groove 311.

[0074] In this embodiment, the device further includes a front-end pulling component 5 for pulling the guide wire. The front-end pulling component 5 is fixedly mounted on the rotating seat 1 and is drivenly connected to the front-end clamping component 3. The front-end pulling component 5, when the front-end clamping component 3 clamps the front end of the guide wire, drives the front-end clamping component 3 to move, cooperating with the clamping structure at the rear end of the guide wire (such as the pulling mechanism in a guide wire bending device according to application number CN202120325668.9) or a human hand, causing the front end of the guide wire to be repeatedly pulled and shaped around the guide wire position 21, ultimately completing the J-bend shaping of the guide wire front end. This method of J-bend shaping of the guide wire front end is more efficient. In other implementations, the front-end pulling component 5 can be omitted, and the guide wire can be continuously pulled by the clamping structure or a human hand to tighten the guide wire and ultimately achieve the J-bend shaping of the guide wire front end.

[0075] In this embodiment, the front pulling component 5 includes a front pulling cylinder 51, which is drivenly connected to the front clamping component 3.

[0076] In this embodiment, the device further includes a guide assembly 6, which has a guide channel 61 for guiding the guide wire. The guide channel 61 and the front end clamping assembly 3 are located on both sides of the guide wire winding position 21. The guide assembly 6 guides the front end of the guide wire through the guide wire winding position 21.

[0077] In this embodiment, a second guide opening 611 is provided at one end of the guide channel 61 away from the guide wire position 21. The width of the second guide opening 611 gradually decreases from one end away from the guide wire position 21 to the other end. The provision of the second guide opening 611 can guide the tip of the guide wire to extend into the guide channel 61.

[0078] In this embodiment, the second guide port 611 is generally truncated cone-shaped.

[0079] In this embodiment, the guide component 6 includes:

[0080] A first guide member 62 is provided with a first guide groove 621;

[0081] The second guide member 63 is provided with a second guide groove 631;

[0082] A guide gripper cylinder 64 is used to control the clamping or separating of the first guide member 62 and the second guide member 63. The first guide member 62 and the second guide member 63 are both driven and connected to the guide gripper cylinder 64. The guide channel 61 is formed by the enclosing of the first guide groove 621 and the second guide groove 631.

[0083] In this embodiment, the wire winding assembly 2 includes a wire winding rod 22, and the wire winding position 21 is a wire winding groove arranged around the wire winding rod 22.

[0084] In this embodiment, the device further includes a support base 7, which is fixed to the frame 9. The rotation drive assembly 4 is fixedly mounted on the support base 7. A rotation sensor 71 is also mounted on the support base 7, and a rotation sensing plate 11 corresponding to the sensor is mounted on the rotating seat 1. The rotation sensor 71 and the rotation sensing plate 11 can acquire the rotation position of the rotating seat 1 in real time.

[0085] Working process: During the J-bend shaping process, firstly, the guide gripper cylinder 64 drives the first guide member 62 and the second guide member 63 to clamp together. At this time, the first guide groove 621 and the second guide groove 631 surround and form a guide channel 61. The guide wire passes through the guide channel 61, passes around the guide wire position 21, and then extends into the clamping groove 311. The clamping groove 311 and the clamping plane 321 cooperate to clamp and fix it.

[0086] Then, the guide gripper cylinder 64 drives the first guide member 62 and the second guide member 63 to separate. Finally, the rotary drive motor 41 drives the rotating seat 1 to rotate around the guide wire position 21 as the axis. The first gripper 31 and the second gripper 32 drive the front end of the guide wire to wrap around the guide wire position 21.

[0087] Finally, with the cooperation of the front-end pulling component 5 and the clamping structure or human hand at the rear end of the guide wire, the front end of the guide wire is repeatedly pulled and shaped around the guide wire position 21 to complete the J-bend shaping of the front end of the guide wire.

[0088] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
