In addition, the two ends of the connecting rod 526 are provided with contacts 527, and the contacts 527 can facilitate connection contact with the slide way, so that the sliding of the connecting part 525 in the slide way is simpler and more reliable. Meanwhile, the length of the connecting rod 526 is greater than that of the first notch 511, so that at least one end of the connecting rod 526 is in contact with the slide way when sliding through the first notch 511, and thus the conductive slip ring 500 can be ensured to have continuous electric connection in the sliding process, so that the current can be stably conducted, and the guide wire conveying device 10 can be stably and reliably used.

As shown in fig. 5 and 6, in some embodiments, the sliding housing 512 is provided with a sliding wiring groove 516, a wire is disposed in the sliding wiring groove 516 and electrically connected to the sliding circuit board 513, a stationary wiring groove 528 is disposed in the stationary housing, and a wire is disposed in the stationary wiring groove 528 and electrically connected to the stationary circuit board 523.

Like this, the wire carries out welded fastening through slip trough 516 and sliding circuit board 513, and the connection of the wire of being convenient for promotes the packaging efficiency of sliding part 510, and can also use welded connection fixed wire and sliding circuit board 513, increases stability. The connection between the lead and the stationary circuit board 523 is the same as the connection between the lead and the sliding circuit board 513, and is not described herein again.

In some embodiments, as shown in fig. 4, the connecting shaft plate 223 includes: a connecting plate 224 and a connecting shaft 225, wherein one side of the connecting plate 224 is abutted against the conductive slip ring 500, and a through hole 226 for the guide wire 11 to pass through is arranged on the connecting plate 224; the connecting plate 224 is fixedly connected with a connecting shaft 225, and at least a part of the connecting shaft 225 is inserted into the gear assembly 222 to be in transmission connection with the gear assembly 222. It should be noted that, in order to improve the structural strength between the connecting plate 224 and the connecting shaft 225, the connecting plate 224 and the connecting shaft 225 may be integrally formed, so that the production process of the connecting shaft plate 223 may be omitted, the connection between the connecting shaft 225 and the connecting plate 224 may be more stable and reliable, and the usability of the connecting shaft plate 223 may be improved. In addition, the production efficiency of connecting shaft plate 223 can also be promoted to use integrated into one piece's mode production connecting shaft plate 223, reduces connecting shaft plate 223's manufacturing cost. When the conductive slip ring 500 is operated to conduct electricity, the pressure sensor 240 can be supplied with electricity or transmit a signal by making an electrical connection with the connection plate 224 through an interference therebetween. Furthermore, the connecting shaft 225 is suitable for being in transmission connection with the gear assembly 222, and the gear assembly 222 is suitable for driving the connecting shaft plate 223 to rotate, so that the rotating effect can be transmitted to the guide wire conveying device 10, and the guide wire conveying device 10 is driven to rotate, so that the effect that the guide wire 11 clamped by the guide wire conveying device 10 rotates is achieved. Preferably, still be equipped with joint 228 on the one side that connecting axle 225 deviates from connecting plate 224, joint 228 can promote the connection effect between connecting axle 225 and the gear assembly 222 for gear assembly 222 can be better transmit the transmission effect to connecting axle board 223 on, thereby let the rotatory effect of seal wire 11 obtain promoting, can restrict the position of connecting axle 225 moreover, thereby let connecting axle 225 and gear assembly 222's transmission be connected more stably. Moreover, a clamp spring may be disposed between the connecting shaft 225 and the gear assembly 222 to improve the connection effect between the connecting shaft 225 and the gear assembly 222, which is not described herein.

In some embodiments, as shown in fig. 4, a mounting slot 227 is formed on the connecting plate 224, the mounting slot 227 is located on a side of the connecting plate 224 facing away from the conductive slip ring 500, and a portion of the pressure sensor 240 is mounted in the mounting slot 227. Thus, since the mounting groove 227 is recessed from the outer peripheral wall of the connecting plate 224, and a part of the structure of the pressure sensor 240 is disposed in the mounting groove 227, the connection between the pressure sensor 240 and the connecting plate 224 is tighter, the power supply effect of the conductive slip ring 500 can be better applied to the pressure sensor 240, and the mounting groove 227 can avoid the pressure sensor 240, so that the structure of the guide wire conveying device 10 is more compact.

The interventional device 20 according to an embodiment of the present invention includes the guidewire delivery apparatus 10 of the interventional device 20 as described above. In this way, the guide wire conveying device 10 is arranged in the interventional device 20, so that the movement of the guide wire 11 is more stable and reliable, the structure of the guide wire conveying device 10 is simpler, the production cost of the guide wire conveying device 10 can be reduced, the structure of the guide wire conveying device 10 can be more compact, and the transportation of the interventional device 20 is simpler.

Other constructions and operations of the interventional device 20 according to embodiments of the invention are known to those of ordinary skill in the art and will not be described in detail herein.
