[0097] Figure 6 It is a top view of a partial structure of a medical catheter assembly provided by an exemplary embodiment of the present utility model.

[0098] As Figure 4 、 Figure 6 、 Figure 7 shown, in a possible embodiment, the direction control assembly 132 includes a first direction control component 1321, a second direction control component 1322, a third direction control component 1323, and a fourth direction control component 1324. The first direction control component 1321, the second direction control component 1322, the third direction control component 1323, and the fourth direction control component 1324 include a traction limiting portion and an engaging portion. The traction limiting portion is provided above the engaging portion. The first direction control component 1321 and the second direction control component 1322 are connected through the engaging portion, and the third direction control component 1323 and the fourth direction control component 1324 are connected through the engaging portion. The other end of the first passive traction component 1333 is wound around the traction limiting portion of the first direction control component 1321, the other end of the first passive traction component 1333 is wound around the traction limiting portion of the second direction control component 1322, the other end of the second active traction component 1332 is wound around the traction limiting portion of the third direction control component 1323, and the other end of the second passive traction component 1334 is wound around the traction limiting portion of the fourth direction control component 1324.

[0100] As an example, the traction limiting part can adopt a dumbbell-shaped roller, with larger ends and a smaller middle part. The middle part can be used as a limiting groove to facilitate the winding of the traction component around the limiting groove of the traction limiting part and limit the traction component to prevent it from slipping out of the traction limiting part.

[0101] The other end of the first active traction component 1331 is wound clockwise in the limiting groove of the traction limiting part of the first direction control component 1321, the other end of the first passive traction component 1333 is wound clockwise in the limiting groove of the traction limiting part of the second direction control component 1322, the other end of the second active traction component 1332 is wound clockwise in the limiting groove of the traction limiting part of the third direction control component 1323, and the other end of the second passive traction component 1334 is wound clockwise in the limiting groove of the traction limiting part of the fourth direction control component 1324.

[0104] Figure 7 It is a partial structural schematic diagram of another medical catheter assembly provided by an exemplary embodiment of the present utility model.

[0105] As Figure 7 shown, in a possible embodiment, the direction control assembly 132 further includes a first traction motor 1325 and a second traction motor 1326. The first traction motor 1325 is arranged at the bottom of the first direction control component 1321 and the second direction control component 1322, and the second traction motor 1326 is arranged at the bottom of the third direction control component 1323 and the fourth direction control component 1324. The first traction motor 1325 is used to control the rotation of the first direction control component 1321 and drive the rotation of the second direction control component 1322, and the second traction motor 1326 is used to control the rotation of the third direction control component 1323 and drive the rotation of the fourth direction control component 1324.

[0106] When the first-direction control member 1321 rotates to tighten or loosen the first active traction member 1331, the medical catheter 131 bends with a first bending radius; when the third-direction control member 1323 rotates to tighten or loosen the second passive traction member 1334, the medical catheter 131 bends with a second bending radius.

[0107] As an example, when the first traction motor 1325 rotates clockwise, the gear of the first-direction control member 1321 rotates clockwise to tighten the first active traction member 1331. Since the first-direction control member 1321 and the second-direction control member 1322 are meshed and connected, the gear of the second-direction control member 1322 rotates counterclockwise to loosen the first passive traction member 1333. One end of the medical catheter 131 bends toward the side connected with the first active traction member 1331, and the medical catheter 131 bends with a first bending radius. The bending arc of the medical catheter 131 changes with the tightening degree of the first active traction member 1331, so as to make the bending arc of the medical catheter 131 adapt to the bending arc of the blood vessel.

[0108] As another example, when the first traction motor 1325 rotates counterclockwise, the gear of the first-direction control member 1321 rotates counterclockwise to loosen the first active traction member 1331, and the gear of the second-direction control member 1322 rotates clockwise to tighten the first passive traction member 1333. One end of the medical catheter bends toward the side connected with the first passive traction member 1333, and the medical catheter 131 bends with a first bending radius. The bending arc of the medical catheter 131 changes with the tightening degree of the first passive traction member 1333, so as to make the bending arc of the medical catheter 131 adapt to the bending arc of the blood vessel.

[0109] As an example, when the second traction motor 1326 rotates clockwise, the gear of the third-direction control member 1323 rotates clockwise to tighten the second active traction member 1332, and the gear of the fourth-direction control member 1324 rotates counterclockwise to loosen the second passive traction member 1334. One end of the medical catheter 131 bends toward the side connected with the second active traction member 1332, and the medical catheter 131 bends with a second bending radius. The bending arc of the medical catheter 131 changes with the tightening degree of the second active traction member 1332, so as to make the bending arc of the medical catheter 131 adapt to the bending arc of the blood vessel.

[0110] As another example, when the second traction motor 1326 rotates counterclockwise, the gear of the third direction control component 1323 rotates counterclockwise to relax the second active traction component 1332, and the gear of the fourth direction control component 1324 rotates clockwise to tighten the second passive traction component 1334. The medical catheter 131 bends with a second bending radius, and the bending radian of the medical catheter 131 changes with the tightening degree of the second passive traction component 1334, realizing that one end of the medical catheter 131 bends toward the side connected with the second passive traction component 1334, and making the bending radian of the medical catheter 131 adapt to the bending radian of the blood vessel.

[0111] In a possible embodiment, by adjusting the first active traction component 1331 and the first passive traction component 1333 connected to the first solder joint 1311 to pull the medical catheter to bend to one side, and at the same time, by adjusting the second active traction component 1332 and the second passive traction component 1334 connected to the second solder joint 1312 to pull the medical catheter to bend to one side, the medical catheter 131 can be bent with different bending radii and form different bending radians, approaching the shape of the real blood vessel.

[0112] Through the above technical solution, by adjusting the traction components on different solder joints at one end of the medical catheter 131, the medical catheter 131 is bent with different bending radii, and by adjusting the tightening degree of the traction components, the medical catheter 131 is bent with different radians, so as to adapt to the bending radian of the blood vessel and realize the diversification of the bending shape of the medical catheter 131.

[0113] Figure 8 It is a schematic structural diagram of a simulation pedal provided by an exemplary embodiment of the present invention.

[0114] As Figure 8 shown, in a possible embodiment, the simulation pedal 140 is arranged above the pedal of the digital subtraction angiography device. The simulation pedal 140 includes a first cam component 131 and a second cam component 132. The first cam component 131 is used to press the first pedal in the pedal of the digital subtraction angiography device, and the second cam component 132 is used to press the second pedal in the pedal of the digital subtraction angiography device.

[0115] Among them, the first pedal can represent the DSA pedal, and the second pedal can represent the fluoroscopy pedal.
