[0002] Disposable medical catheter / wire products are the most frequently used conventional surgical instruments in minimally invasive surgeries. After the wire enters the human body, it needs to pass through a series of blood vessel bifurcations to reach the lesion site, which poses high requirements for the deflection of the distal end of the wire. When the lesion location in the patient's body is relatively complex, the blood vessel bifurcation angle is relatively large, and the distal end of the wire is repeatedly shaped, a magnetic guide wire needs to be selected for interventional surgery. When the magnetic guide wire has strong deflection performance, it can make the magnetic guide wire more easily pass through complex intravascular bifurcations and move in a rapidly changing intravascular scenario.

An external magnet is used to generate a magnetic field space with a gradient change in the trunk of the patient, and the force generated on the distal magnet of the magnetic guide wire is changed by controlling the angle and distance of the external magnet, so as to change the orientation of the distal end of the magnetic guide wire and achieve the purpose of guiding the distal end of the magnetic guide wire.

Detailed implementation manners

[0041] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0042] Referring to Figures 1 to 17 as shown, the embodiment of the present utility model provides an interventional magnetic guide wire magnetic field control device, including:

[0043] A support and regulation mechanism 1, including an adjustment component and a rotation component connected to the end of the adjustment component, the adjustment component being used to adjust the lifting and rotation of the rotation component in a horizontal plane;

[0045] wherein, the rotation component is connected to the middle of the control rod 2020, and the angle of the magnet control mechanism 2 is adjusted by operating the proximal end of the control rod 2020.

[0046] Specifically, the support and regulation mechanism 1 in this embodiment drives the entire magnet manipulation mechanism 2 to move up and down, rotate, and adjust the pitch angle. That is, the magnet manipulation mechanism 2 can be roughly adjusted to the vicinity of the patient's affected area (i.e., preliminary adjustment) through the support and regulation mechanism 1. Then, by remotely controlling the control lever 2020 in this embodiment, the orientation of the magnet assembly 21 can be more precisely micro-adjusted (i.e., precise adjustment) through the orientation adjustment component. It can be seen that the operation of this application is simple and occupies little space. Through the combination of preliminary adjustment and precise adjustment, the adjustment is more precise. In this embodiment, the angle of the magnet manipulation mechanism 2 can be adjusted by operating the proximal end of the control lever 2020, which enables single-handed operation and is convenient and fast.

[0047] In this embodiment, the preliminary adjustment and precise adjustment are used to adjust the angle of the magnet assembly 21 and the distance between the magnet assembly 21 and the magnetic guide wire, so as to change the force generated on the distal magnet 211 of the magnetic guide wire, change the orientation of the distal end of the magnetic guide wire, and achieve the purpose of guiding the distal magnetic guide wire.

[0048] Furthermore, the orientation adjustment component includes a housing, a magnetic control rotating member 203, and a driving member; the magnetic control rotating member 203 is rotatably connected in the housing; the driving member is arranged in the control lever, and the end of the driving member is connected to the magnetic control rotating member 203 for driving the magnetic control rotating member 203 to rotate in the housing; the magnetic control rotating member 203 is fixedly connected to the magnet assembly 21. In some embodiments, the housing includes a fixed cover 30 and a fixed shell 31. The fixed cover 30 is provided with a first bearing groove 301 and a first thread 302. The fixed shell 31 is provided with a second thread 311 and a second bearing groove 312, and the first thread 302 is connected to the second thread 311. A first bearing 332 and a second bearing 335 are respectively placed in the first bearing groove 301 and the second bearing groove 312. The magnetic control rotating member 203 passes through the first bearing 335 and the second bearing 335 and is rotatably connected to the fixed cover 30 and the fixed shell 31 through the first bearing 335 and the second bearing 335.

[0049] The driving member includes a runner 2011, two round wheels 2013, two wire ropes 204, and a first fixed shaft 2012; a cavity extending along its axis is provided in the control lever 2020, and one end of the cavity passes through the fixed housing 31 and communicates with the magnetic control rotating member 203; a notch penetrating through its wall body is provided on the proximal rod body of the control lever 2020, and the notch communicates with the cavity; the runner 2011 is rotatably connected to the control lever 2020 through the first fixed shaft 2012, and the runner 2011 is exposed outside the control lever 2020 from the notch; two round wheels 2013 are respectively fixedly connected to both sides of the runner 2011, and the round wheels 2013 rotate synchronously with the runner 2011; one ends of the two wire ropes 204 are respectively wound around the two round wheels 2013, and the wire ropes 204 are fixedly connected to the round wheels 2013; in some embodiments, wire grooves are provided on the round wheels 2013, and the wire ropes 204 are wound in the wire grooves. The other ends of the two wire ropes 204 pass through the cavity and are connected to the magnetic control rotating member 203.

[0050] The magnetic control rotating member 203 includes a rotating shaft 333, and an annular groove 3331 coaxial with it is provided on the rotating shaft 333; the other ends of the two wire ropes 204 are respectively fixedly connected to the rotating shaft 333 and are arranged in the annular groove 3331. The ends of the two wire ropes 204 connected to the rotating shaft 333 can also be separated, and the two wire ropes 204 are respectively fixedly connected to the rotating shaft 333. Of course, the ends of the two wire ropes 204 connected to the rotating shaft 333 can be connected as a whole, and only one point needs to be fixedly connected to the rotating shaft 333. In this embodiment, the ends of the two wire ropes 204 connected to the rotating shaft 333 are connected as a whole. A concave hole 3334 coaxial with it is provided at the top of the rotating shaft 333. In the rotating shaft 333, through holes extending radially are provided at the position where the annular groove 3331 is provided, and the number of the through holes is two. The through holes communicate with the concave hole 3334. The wire rope 204 is located in the concave hole 3334 after passing through one of the through holes, and a pressing shaft 336 is inserted and fixed in the concave hole 3334. The pressing shaft 336 presses the wire rope 204 located in the concave hole 3334, and then the wire rope 204 passes out from the other through hole.

[0051] In some embodiments, the magnet assembly 21 includes a magnet 211 and a housing 212 covering the outside of the magnet 211. The shape of the magnet 211 is not limited, and it can be a cylinder, a cube, a cuboid, a spherical ball, etc. The magnetic field control rotating member 203 is connected to the housing 212. Specifically, a threaded through hole 3333 is provided on the rotating shaft 333. The housing 212 is sleeved on the rotating shaft 333, and a threaded hole is further provided at the position where the housing 212 is connected to the rotating shaft 333. The threaded hole and the threaded through hole 3333 are connected by bolts. There can be multiple threaded holes. In this embodiment, there are multiple threaded holes. Two threaded holes are arranged corresponding to each other along the radial direction of the rotating shaft 333, and the threaded through hole 3333 penetrates through the rotating shaft 333. The two threaded holes are respectively connected to the threaded through hole 3333 by a bolt. Such a connection is more stable and reliable, and is convenient for installation and disassembly.

[0052] Specifically, in this embodiment, the operator can rotate the runner 2011 back and forth in the forward and reverse directions at the distal end, and the rotating shaft 333 can be rotated through the pull wire 204, so as to drive the magnet assembly 21 to rotate with the rotating shaft 333 to slightly adjust the orientation of the magnet assembly 21. When the magnetic guide wire is used for interventional surgery, it is often combined with CT detection, and there will be radiation. Therefore, in this application, the operator can perform remote single-handed operation, which is convenient for operation and avoids the radiation risk for the operator.

[0053] Further, the magnetic field control rotating member 203 further includes a fastener 334, a screwing bolt 32 and a positioning member; the fastener 334 is an annular member with a break. The fastener 334 is sleeved on the large circular shaft 3332 of the rotating shaft 333. First threaded holes 3342 are correspondingly provided at positions on both sides of the break of the fastener 334. A first through hole 313 corresponding to the first threaded hole 3342 is provided on the fixed shell 31 of the housing. After the screwing bolt 32 passes through the first through hole 313, the thread 321 on the screwing bolt 32 is threadedly connected to the first threaded hole 3342. By adjusting the depth of the screwing bolt 32 screwed into the first threaded hole 3342, the size of the break is adjusted, that is, by rotating the screwing bolt 32, the fastener 334 is deformed to tightly hold the rotating shaft 333. At this time, a damping effect is formed, so as to adjust the degree of the fastener 334 holding the magnetic field control rotating member 203, so as to achieve the adjustment of the damping size of the rotation of the magnetic field control rotating member 203; the fastener 334 is connected to the fixed shell 31 of the housing through the positioning member, and is used to limit the rotation of the fastener 334 with the magnetic field control rotating member 203. In some embodiments, the positioning member includes a positioning shaft 331, a positioning blind hole 314 and a second through hole 3341. The positioning blind hole 314 is provided on the fixed shell 31, the second through hole 3341 is provided on the fastener 334 and is correspondingly provided with the positioning blind hole 314, and the positioning shaft 331 is arranged in the second through hole 3341 and the positioning blind hole 314.

In some embodiments, a reversing wheel set is provided at each turning point of the bent shape in the cavity. A reversing wheel set includes two reversing wheels 2022, and the reversing wheels 2022 are rotatably connected to the joystick 2020 through the second fixed shaft 2021; thus, the middle parts of the two wire ropes 204 are respectively wound around the reversing wheels 2022. In this way, the wire ropes 204 are reversed through multiple groups of reversing wheel sets. Specifically, the intermediate rod body in this embodiment serves as a fulcrum, and by the operator controlling the proximal rod body, the angle adjustment of the magnet control mechanism 2 relative to the adjustment assembly can be achieved through the rotating assembly. Since the magnet assembly 21 is relatively heavy, the distal rod body is designed to be bent, which is convenient for the operator to operate with one hand. At the same time, when the operator stands beside the patient, the orientation of the magnet assembly 21 close to the patient's affected area (for example, the ear) can be adjusted (the magnet assembly 21 cannot be in close contact with the patient, and some space needs to be reserved to prevent collisions).

[0055] Further, the adjustment assembly includes a straight rod 12, a first rotating shaft 13, and an adjustment member; the straight rod 12 is connected to the top of the bottom plate 11; the adjustment member is rotatably connected to the straight rod 12 through the first rotating shaft 13. The first rotating shaft 13 includes a fixed end and a rotating end. The fixed end is fixedly connected to the top end of the straight rod 12, the rotating end is connected to the adjustment member, and the rotating end is rotatably connected to the fixed end.

[0056] Further, the adjustment member includes a first adjustment arm 14 and a second adjustment arm 16. Two ends of the first adjustment arm 14 are respectively hinged to the first rotating shaft 13 and one end of the second adjustment arm 16, and the other end of the second adjustment arm 16 is hinged to the rotating assembly.

One end of the first adjustment arm 14 close to the second adjustment arm 16 is hinged to the intermediate connecting member 15, and one end of the second adjustment arm 16 close to the first adjustment arm 14 is hinged to the intermediate connecting member 15. A terminal connecting member 17 is connected to the end of the second adjustment arm 16, and the second adjustment arm 16 is hinged to the rotating assembly through the terminal connecting member 17. For example, the second adjustment arm 16 is hinged to the terminal connecting member 17, and the terminal connecting member 17 is fixedly connected to the rotating assembly. Elastic members are further provided inside the first adjustment arm 14 and the second adjustment arm 16. The elastic members include, but are not limited to, tension springs, springs, and gas springs. The setting of the elastic members ensures that the first adjustment arm 14 and the second adjustment arm 16 can be maintained at any angle.

[0057] Further, the rotating assembly includes a universal ball head 18 and a second rotating shaft 1820. The universal ball head 18 includes a concave spherical cylinder 1811, a ball head 1812, and an extension rod 1813. The concave spherical cylinder 1811 and the ball head 1812 form a ball hinge pair. The second rotating shaft 1820 is connected to the ball head 1812 through the extension rod 1813; the control rod 2020 is connected to the second rotating shaft 1820.

The circular hole 1821 and the threaded hole are both provided on the body and are in communication with each other. The operating rod of the magnet control mechanism 2 passes through the circular hole 1821, and then the locking bolt 1822 is screwed into the threaded hole and abuts against the outer wall of the operating rod. Further, in order to make the connection between the operating rod and the second rotating shaft 1820 more stable and reliable, a groove 2023 is provided on the operating rod, and the body of the second rotating shaft 1820 is clamped in the groove 2023.

[0058] Further, the support control mechanism 1 further includes a moving assembly connected to the adjustment assembly. The moving assembly is configured to drive the support control mechanism 1 to move, facilitating the free movement of the present application. In some embodiments, the moving assembly includes lockable universal wheels 10 and a bottom plate 11.
