the guide wire guiding device also comprises a standby driving part 3 which is arranged at one end of the shell 1 far away from the guide wire installation position, and the standby driving part 3 is also connected with the bidirectional traction part 2;
it should be noted that, during the clinical continuous interventional operation, the thumb holding the hand is continuously used to drive the bidirectional traction member 2 to work, which is very likely to cause hand fatigue, at this time, when the driving knob 12 cannot be moved comfortably, the hand holding the housing 1 can be used to keep the housing 1 and the catheter positioned, and then the spare driving member 3 is used by the other idle hand to continuously and comfortably drive the bidirectional traction member 2 to work to rotatably intervene the guide wire.
As an example:
the bidirectional traction part 2 comprises an inner frame 21 which is rotatably arranged in the shell 1, the inner frame 21 is of a hollow rectangular frame structure with an open side, but not limited to, two rotating shafts one 22 which are parallel to each other and perpendicular to the extending direction of the shell 1 are arranged in the inner frame 21, outer rollers 23 are arranged on the outer sides of the two rotating shafts one 22, through holes 24 are formed in the two sides of the inner frame 21, and when a guide wire penetrates through the shell 1, the guide wire simultaneously penetrates through the two through holes 24, passes through the two outer rollers 23 and is in close contact with the two outer rollers 23;

As an example:
the auxiliary tube 4 comprises a screwed tube 41 with external threads, the screwed tube 41 is installed in the through tube 211 in a threaded manner, one end of the screwed tube 41 extends to the outer side of the through tube 211, an auxiliary knob 42 is arranged on the outer side of one end of the screwed tube located outside the through tube 211, and the screwed tube 41 can be stably and conveniently driven to perform spiral displacement by directly rotating the auxiliary knob 42;

the handle further comprises a first ratchet mechanism 33 and a second ratchet mechanism 34 which are arranged on the outer side of the straight-through pipe 211, the first ratchet mechanism 33 is arranged between the first worm wheel 25 and the straight-through pipe 211, and the second ratchet mechanism 34 is arranged between the holding rod 31 and the straight-through pipe 211.
It should be noted that, for the first ratchet mechanism 33 and the second ratchet mechanism 34, when the driving shaft 11 drives the first worm wheel 25 to rotate clockwise (under the condition that the holding rod 31 is over against the human eye), the straight-through tube 211 is driven by the first ratchet mechanism 33 to rotate together, and when the straight-through tube 211 actively rotates clockwise, the guide wire is normally conveyed and used by the unidirectional rotation of the second ratchet mechanism 34 without driving the holding rod 31 to synchronously rotate forcibly, and the holding rod 31 is not moved when the knob 12 is rotationally driven, so that the use requirement is met;
when the butt joint component 32 is used for canceling the butt joint of the holding rod 31 and rotating the holding rod 31, at this time, the holding rod 31 actively rotates clockwise, and the one-way rotation capability of the ratchet mechanism II 34 is used for driving the straight-through pipe 211 to synchronously rotate clockwise, it should be noted that when the straight-through pipe 211 actively rotates clockwise, the ratchet mechanism I33 is not synchronous with the rotation direction of the worm wheel I25, at this time, the holding rod 31 is rotated to drive the knob 12 and the driving shaft 11 to be in a non-rotating state, and further through the design, the standby driving part 3 and the driving shaft 11 are ensured not to be interfered with each other, so that the guide wire can be comfortably and stably used for spiral conveying.
As an example:
the abutting part 32 comprises a threaded collar 321 with internal threads, the outer sides of the opposite ends of the holding rod 31 and the shell 1 are respectively provided with an outer thread 322, the threaded collar 321 integrally abuts the holding rod 31 and the shell 1 by using the outer threads 322, and further the threaded collar 321 is used for ensuring the detachable abutting of the holding rod 31 and the shell 1, namely when the threaded collar 321 is simultaneously arranged at the ends of the shell 1 and the holding rod 31, the holding rod 31 cannot move;
and the length of the outer thread 322 on the holding rod 31 is greater than the width of the thread collar 321, so that the thread collar 321 can be completely screwed onto the holding rod 31, and at this time, the thread collar 321 has no any restriction on the housing 1 and the holding rod 31, so as to ensure that the holding rod 31 can be rotated and driven arbitrarily.
