[0021] The following is combined Figures 1 to 2 This describes a medical guidewire tip shaping device according to an embodiment of the present invention.

[0022] A medical guidewire tip shaping device includes a base plate 1, a turntable 2, a motor 3, a clamping member 4, a positioning post 5, a conveying post 6, a feeding section 7, and a pulling member 8. The turntable 2 is rotatably mounted on the top of one end of the base plate 1. The motor 3 is mounted on the bottom of the base plate 1, and the driving end of the motor 3 passes through the top of the base plate 1. The driving end of the motor 3 is connected to the turntable 2 and drives the turntable 2 to rotate. The positioning post 5 is mounted at the center of the top of the turntable 2. The clamping member 4 is fixedly mounted on the turntable 2. The clamping member 4 and the conveying post 6 are respectively mounted on the positioning post. On the left and right sides of the positioning column 5, the clamping member 4 and the conveying column 6 are installed in front of or behind the positioning column 5; the center of the conveying column 6 is provided with a through hole 61, and the position of the through hole 61 corresponds to the center of the clamping end of the clamping member 4; the feeding part 7 is installed on the top of the substrate 1, and the conveying column 6 is installed on the side close to the feeding part 7. The feeding part 7 is used to convey the guide wire into the through hole 61; a pull member 8 is provided at the end of the feeding part 7 away from the through hole 61. One end of the pull member 8 is connected to the feeding part 7, and the other end of the pull member 8 hangs down from the end wall of the substrate 1.

[0023] A medical guidewire tip shaping device is used to bend the tip of a medical guidewire. The guidewire tip first passes through a through hole 61 to a clamping member 4. The clamping member 4 holds the tip of the guidewire. A motor 3 drives a turntable 2 to rotate, which in turn drives the clamping member 4 to rotate. At this time, one side of the guidewire is held against a positioning post 5, and the position of the guidewire is still limited within the through hole 61. The guidewire is bent by the rotation of the clamping member 4. The bending angle of the guidewire can be adjusted according to the rotation angle of the clamping member 4, so that the curvature of the guidewire tip can be controlled. Multiple guidewires can be bent through this device, so that the bending angle of the tips of multiple guidewires is consistent. Using this device to bend the guidewire can avoid causing other unnecessary damage to the guidewire.

[0024] The puller 8 allows the guide wire to be pulled by the feeding part 7 during the rotation and bending process of the clamped part 4, so that the guide wire can adapt to the tension during the bending process and avoid damage to the guide wire.

[0025] Specifically, the clamping component 4 includes an upper clamping block 41, a lower clamping block 42, an upper cylinder 43, and a lower cylinder 44. The upper clamping block 41 and the lower clamping block 42 are movably installed correspondingly. The driving end of the upper cylinder 43 is connected to the upper clamping block 41 and drives the upper clamping block 41 to move. The driving end of the lower cylinder 44 is connected to the lower clamping block 42 and drives the lower clamping block 42 to move. The upper clamping block 41 and the lower clamping block 42 cooperate to clamp the guide wire. The upper clamping block 41 and the lower clamping block 42 clamp the end of the guide wire and then bend the guide wire. The guide wire can be directly placed between the upper clamping block 41 and the lower clamping block 42, and the upper clamping block 41 and the lower clamping block 42 then clamp the guide wire, which facilitates the bending of the guide wire.

[0026] Specifically, an abutment block 9 is provided on the side of the lower clamping block 42 away from the positioning post 5. The abutment block 9 is used to hold and limit the position of the guide wire. When the guide wire is inserted into the upper clamping block 41 and the lower clamping block 42, the guide wire is pushed directly inward until it is held against the abutment block 9. This ensures the bending length of each guide wire tip and maintains the consistency of the bending of each guide wire.

[0027] To further explain, the end of the conveyor column 6 near the feeding section 7 is provided with an arc groove. The arc groove facilitates the pushing of the guide wire into the through hole 61.

[0028] Specifically, the feeding unit 7 includes a support block 71, a guide block 72, and a telescopic mechanism 73. The support block 71 is fixedly installed above the substrate 1 and has a clearance hole. The upper end of the guide block 72 passes through the clearance hole. The drive end of the telescopic mechanism 73 is connected to the guide block 72 and pushes the guide block 72 to move left and right within the clearance hole. When the guide wire is placed at the guide block 72, the telescopic mechanism 73 pushes the support block 71 to deliver the guide wire into the through hole 61 and directly to the contact block 9.

[0029] To further explain, the top of the guide block 72 is provided with a clamping groove, the vertical surface of which is V-shaped. The clamping groove facilitates the placement and limiting of the guide wire.

[0030] Specifically, the pull member 8 includes a pull rope 81 and a pull block 82. One end of the pull rope 81 is connected to the guide block 72, and the other end of the pull rope 81 is tied to the pull block 82. The pull block 82 is suspended from the tail end of the base plate 1 by the pull rope 81. This allows the guide wire to move as a whole with the bending force during the bending process.

[0031] Specifically, a pulley 10 is provided at the top of the tail end of the base plate 1, and a pull rope 81 is installed at the pulley 10. This facilitates the movement of the pull rope 81.

[0032] Other components and operations of the medical guidewire tip shaping device according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0033] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
