[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a guiding device for the entry of a guide wire in urinary lithiasis surgery, including a rubber head 1. The center of the bottom of the rubber head 1 is fixedly connected with a guiding needle 3, and the guiding needle 3 is communicated with the inside of the rubber head 1. The top ends inside the rubber head 1 are symmetrically and rotatably connected with first guiding wheels 4, and the bottom ends inside the rubber head 1 are symmetrically and rotatably connected with third guiding wheels 6. The area between the first guiding wheels 4 and the third guiding wheels 6 inside the rubber head 1 is symmetrically and rotatably connected with second guiding wheels 5. Through the cooperative setting among the first guiding wheels 4, the second guiding wheels 5 and the third guiding wheels 6, the first guiding wheels 4 and the third guiding wheels 6 are driven to rotate by a crank 10, driving the guide wire to move into the inside of the rubber head 1. Under the extrusion and pulling of the first guiding wheels 4, the second guiding wheels 5 and the third guiding wheels 6, the straight extension of the guide wire is ensured.
[0020] It should be noted that when the present utility model is used, the end of the guide wire is placed between the two first guiding wheels 4, and then the crank 10 is rotated to make the first gear 7 rotate. The rotation of the first gear 7 drives the two first guiding wheels 4 to rotate. Under the rotation of the first guiding wheels 4, the two third guiding wheels 6 are driven to rotate through the transmission connection between the two belt wheels 9. Thus, under the guidance of the first guiding wheels 4 and the third guiding wheels 6, the guide wire is driven to move vertically downward, and its end smoothly enters the inside of the guiding needle 3, thereby ensuring the straight extension of the guide wire. The anti-slip pads 11 outside the first guiding wheels 4, the second guiding wheels 5 and the third guiding wheels 6 play a good anti-slip effect, facilitating the stable pulling of the movement of the guide wire.
[0021] The end parts of the central axes of the two first guiding wheels 4 both pass through the rubber head 1 and are fixedly connected with first gears 7, and the two first gears 7 are meshed with each other. The end parts of the central axes of the two third guiding wheels 6 both pass through the rubber head 1 and are fixedly connected with second gears 8, and the two second gears 8 are meshed with each other.
[0022] It should be noted that when the crank 10 is rotated to make the first gear 7 rotate, the rotation of the first gear 7 drives the two first guiding wheels 4 to rotate. Under the rotation of the first guiding wheels 4, the second gear 8 is driven to rotate through the transmission connection between the two belt wheels 9. Through the meshing connection between the two second gears 8, the third guiding wheels 6 are driven to rotate, so that the two third guiding wheels 6 extrude and pull the guide wire to move.
[0023] The end parts of the central axes of the first guiding wheels 4 and the third guiding wheels 6 far away from the first gears 7 both pass through the rubber head 1 and are fixedly connected with belt wheels 9, and the two belt wheels 9 are connected by a belt in a transmission manner.
[0024] It should be noted that by rotating the crank 10, the rotation of the first gear 7 can be controlled. Through the meshing connection between the two first gears 7, the two first guide wheels 4 are rotated. The two first guide wheels 4 squeeze and pull the wire to move downward. The rotation of the first guide wheel 4 causes the pulley 9 to rotate. Through the transmission connection between the two pulleys 9, the second gear 8 is rotated.
[0025] A crank 10 is fixedly connected to the end of the central axis of the first gear 7.
[0026] It should be noted that by rotating the crank 10, the rotation of the first guide wheel 4 and the third guide wheel 6 can be controlled simultaneously.
[0027] Anti-slip pads 11 are fixedly connected to the outer sides of the first guide wheel 4, the second guide wheel 5, and the third guide wheel 6.
[0028] A cross plate 2 is fixedly connected to the outside of the bottom of the rubber head 1 and is located outside the guiding needle 3.
[0029] It should be noted that when using the rubber head 1, the rubber head 1 can be controlled by holding the cross plate 2 by hand.
[0030] The cross section of the inner bottom end of the rubber head 1 is in a conical structure.
[0031] It should be noted that by rotating the crank 10, the first gear 7 is rotated. The rotation of the first gear 7 drives the two first guide wheels 4 to rotate. Under the rotation of the first guide wheel 4, through the transmission connection between the two pulleys 9, the two third guide wheels 6 are rotated. Thus, under the guidance of the first guide wheel 4 and the third guide wheel 6, the wire is driven to move vertically downward. During the downward movement of the wire, the rubber head with a conical cross section at the bottom plays a certain guiding role in the downward movement of the wire, facilitating the smooth entry of the wire into the guiding needle 3.
