The following embodiments are only a part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0042] With the continuous development of medical technology, electromagnetic positioning technology is widely used in image-guided surgery and interventional medical systems. Electromagnetic positioning technology mainly assists the positioning and navigation of intracorporeal interventional devices through the magnetic field generated by the magnetic field generator outside the body. The setting position of the magnetic field generator arranged outside the body can directly affect the positioning accuracy of the intracorporeal interventional device, so when in use, the magnetic field generator needs to be adjusted to the appropriate position according to the surgical site of the body. However, due to the limitations of narrow surgical space, insufficient flexibility of magnetic field generator operation and other factors, the placement position of the magnetic field generator is too single, and it is difficult to adjust it to the appropriate position during the operation, which is not convenient to use and is difficult to meet the needs of various surgical scenes.
[0043] In order to solve the above technical problems, the present application provides a medical magnetic field generator moving vehicle and a medical magnetic field generator system.
[0044] Referring to Figures 1 to 2 In an embodiment of the present application, a medical magnetic field generator moving vehicle is provided, which comprises a chassis 1, a lifting assembly 2, a supporting assembly 3 and a magnetic field generator 4. The chassis 1 is provided with a plurality of traveling wheels 11, and when needed, the chassis 1 can be moved to the appropriate position according to the needs. The traveling wheels 11 can be unpowered traveling wheels 11, or powered traveling wheels 11. The powered traveling wheels 11 do not need to be pushed by the user, and can move autonomously under the control of the control device.
[0045] The lifting assembly 2 is arranged on the chassis 1 in the vertical direction; the lifting assembly 2 can be directly welded to the chassis 1, or can be detachably connected to the chassis 1. For example, in a detachable manner, different models and lifting weights of the lifting assembly 2 can be conveniently replaced to meet the needs of lifting magnetic field generators 4 of different weights and have a wider range of use.
[0046] The support assembly 3 has a first end and a second end, the first end is connected with the upward end of the lifting assembly 2 through the first locking device 21; the magnetic field generator 4 is connected with the second end of the support assembly 3 through the second locking device 22; the support assembly 3 and the lifting assembly 2 have one rotational degree of freedom, and the magnetic field generator 4 and the support assembly 3 also have one rotational degree of freedom. The first locking device 21 and the second locking device 22 both have a locked state and an unlocked state. When the first locking device 21 and the second locking device 22 are in the unlocked state, the magnetic field generator 4 is decoupled relative to the lifting assembly 2 and the support assembly 3, and the position of the magnetic field generator 4 can be adjusted flexibly at this time. After the magnetic field generator 4 is adjusted to the appropriate position, the first locking device 21 and the second locking device 22 are switched to the locked state, so that the lifting assembly 2 is fixed relative to the support assembly 3, and the magnetic field generator 4 is fixed relative to the lifting assembly 2. In the process of the operation, the magnetic field generator 4 can be stably kept in the adjusted appropriate position, so as to be fixedly placed at the appropriate angle around the patient.
[0047] In the technical scheme provided in the embodiment of the application, the magnetic field generator 4 is arranged on the movable base plate 1, the support assembly 3 is connected with the lifting assembly 2 through the first locking device 21; the magnetic field generator 4 is connected with the support assembly 3 through the second locking device 22; after the first locking device 21 and the second locking device 22 are switched to the unlocked state, the magnetic field generator 4 is decoupled with the lifting assembly 2, and the position of the magnetic field generator 4 can be moved and adjusted flexibly. After the first locking device 21 and the second locking device 22 are switched to the locked state, the position of the magnetic field generator 4 is fixed. The magnetic field generator 4 has more operation degrees of freedom, and can meet the needs of different operation scenes.
[0048] Referring to Figure 1 and Figure 2 In one embodiment provided in the application, the support assembly 3 includes a plurality of connecting rods, the plurality of connecting rods are connected in a loop; the connecting rods are provided with third locking devices 33 at the connection positions. The third locking devices 33 also have a locked state and an unlocked state; in the unlocked state, the positions of the connecting rods relative to each other are adjusted, and after the adjustment is completed, the third locking devices 33 can be switched to the locked state, and the positions of the plurality of connecting rods are kept fixed.
[0049] For example, the support assembly 3 can include a first connecting rod 31 and a second connecting rod 32, one end of the first connecting rod 31 is connected with the lifting assembly 2, the other end of the first connecting rod 31 is connected with one end of the second connecting rod 32, a third locking device 33 is arranged at the connecting joint, and the other end of the second connecting rod 32 is connected with the magnetic field generator 4. When the third locking device 33 is in an unlocked state, the positions of the first connecting rod 31 and the second connecting rod 32 can be adjusted. After the adjustment is completed, the third locking device 33 is switched to a locked state, and the positions of the first connecting rod 31 and the second connecting rod 32 are fixed. In the technical solution of the present application, the support assembly 3 includes a plurality of connecting rods, the positions of the plurality of connecting rods can be adjusted relatively, the support assembly 3 can have a multi-angle position adjustment mode, and the operation degree of freedom of the magnetic field generator 4 is also higher.
[0050] Referring to Figure 2 and Figure 3 In an embodiment provided in the present application, the connecting rod is in a bent structure in the projection in the length direction of the connecting rod; the connecting rod includes straight sections at both ends and an inclined section in the middle. The magnetic field generator 4 can be connected to the front end of the straight section, and the magnetic field generator 4 can also be connected to the side of the connecting rod, specifically, the side of the end of the straight section of the connecting rod. The connecting rod is designed to be in a bent structure, which can facilitate the storage of a plurality of connecting rods, and the plurality of connecting rods can be overlapped and stored when the support assembly 3 is in an unfolded state, so that interference is avoided.
[0051] In order to further improve the flexibility of the medical magnetic field generator mobile vehicle, referring to Figure 1 and Figure 2 In an embodiment provided in the present application, the lifting assembly 2 further includes a steering seat 23, the steering seat 23 is rotatably connected to the upward end of the lifting assembly 2, and the steering seat 23 can rotate around the axis of the lifting assembly 2. In this way, when the setting angle of the magnetic field generator 4 needs to be adjusted when the support assembly 3 is in a locked state, the setting angle of the magnetic field generator 4 can be directly adjusted by rotating the steering seat 23, so that the operation of adjusting the position of the magnetic field generator 4 is more convenient and fast.
[0052] Further, the steering seat 23 is provided with a locking piece 24, the locking piece 24 is arranged at the connecting joint of the steering seat 23 and the lifting assembly 2, and when the steering seat 23 is rotated to a suitable position, the steering seat 23 and the lifting assembly 2 can be locked by the locking piece 24, so that the position between the steering seat 23 and the lifting assembly 2 is fixed.
[0053] Referring to Figure 4In another embodiment provided in the present application, the turning seat 23 is provided with a connecting device 25; the connecting device 25 is provided with a sliding groove 251 which can be connected to the sliding rail of other equipment. After the connecting device 25 is connected to the sliding rail, the sliding rail can limit the moving direction of the medical magnetic field generator moving vehicle, and the medical magnetic field generator moving vehicle is more stable during the moving process. The other equipment includes but is not limited to the sickbed in the operating room, other surgical equipment, etc. By connecting the medical magnetic field generator moving vehicle to other equipment through the sliding rail, the medical magnetic field generator moving vehicle and other equipment can be interlocked, which is more convenient to control and better to use.
[0054] Further, referring to Figures 1 to 4 , the lifting assembly 2 includes a fixed rod 26, a lifting rod 27, a lifting device and a pedal 29; the fixed rod 26 is arranged on the chassis 1, the lifting rod 27 is connected with the fixed rod 26, and the lifting device is arranged between the fixed rod 26 and the lifting rod 27 to drive the lifting rod 27 to lift relative to the fixed rod 26; when the magnetic field generator 4 needs to rise, the lifting device outputs a driving force to drive the lifting rod 27 to rise. When the magnetic field generator 4 needs to descend, the lifting device is disconnected from the limit, and the lifting rod 27 descends relative to the fixed rod 26. In the technical solution provided in the present application, the lifting action is realized through the lifting assembly 2, the moving distance of the magnetic field generator 4 at the end of the supporting assembly 3 is increased, and the supporting assembly 3 has a position adjustment mode with multiple heights. Correspondingly, the moving range of the magnetic field generator 4 is also increased, and the flexibility of the magnetic field generator 4 is better.
[0055] In order to facilitate the control of the lifting action of the lifting assembly 2, the lifting assembly 2 further includes a pedal 29 which can control the lifting device; the pedal 29 is arranged on the chassis 1 and connected with the lifting device to control the action of the lifting device. The pedal 29 can be one or multiple, for example, the pedal 29 includes a rising pedal and a descending pedal. When a medical staff steps on the rising pedal, the lifting assembly 2 rises, and when the medical staff steps on the descending pedal, the lifting assembly 2 descends. Alternatively, when the medical staff steps on the pedal 29, the lifting device is unlocked, and under the auxiliary driving force of the medical staff, the lifting rod 27 can rise or descend.
[0056] Further, although the lifting device has a certain locking function, in some fine use scenarios, it is also necessary to keep the position of the lifting assembly 2 more stable. In an embodiment provided in the present application, the lifting assembly 2 further includes a locking piece 30 which is arranged at the connection between the fixed rod 26 and the lifting rod 27. The locking piece 30 can be switched between a locked state and an unlocked state. After the lifting action of the lifting assembly 2 is completed, the medical staff can switch the locking piece 30 to the locked state, so that the position between the fixed rod 26 and the lifting rod 27 will be kept relatively fixed.
[0057] See Figure 1 and Figure 2 , in an embodiment provided by the present application, the medical magnetic field generator mobile cart further includes a storage basket 5. A connection platform is provided on the side wall of the fixed rod 26, and the storage basket 5 is detachably connected to the connection platform. The storage basket 5 can be connected to the connection platform by a buckle or by a fastener. By detachably connecting the storage basket 5 to the fixed rod 26, it is convenient to replace storage baskets 5 of different sizes and functions. Some items required during the operation can be placed in the storage basket 5, which is convenient for medical staff to pick up at will. In addition, some miniaturized devices supporting the magnetic field generator 4 can also be placed in the storage basket 5.
[0058] The better the stability of the chassis 1, the better the stability of the medical magnetic field generator mobile cart. See Figures 1 to 4 , in an embodiment provided by the present application, the chassis 1 of the medical magnetic field generator mobile cart is of an "H" - shaped structure, and the traveling wheels 11 are universal wheels. Specifically, the traveling wheels 11 are located at the four corners of the chassis 1, which will make the stability of the chassis 1 better. The traveling wheels 11 being universal wheels can facilitate the random movement of the chassis 1. In this way, in a narrow operating room, the chassis 1 can be flexibly moved and transferred.
[0059] In addition, after the position of the magnetic field generator 4 is adjusted, it is also necessary to keep the position of the magnetic field generator 4 fixed. In addition, during the operation, in order to prevent the medical magnetic field generator mobile cart from being accidentally pushed away. See Figure 1 and Figure 2 , in an embodiment provided by the present application, a braking device 12 is provided on the chassis 1. The braking device 12 has a braking state and an active state, and the braking device 12 can switch back and forth between the braking state and the active state. When the position of the magnetic field generator 4 needs to be adjusted, the braking device 12 is in the active state, and the chassis 1 can move freely; after operating the braking device 12 to switch to the braking state, the chassis 1 is limited relative to the ground, and the chassis 1 cannot move freely.
[0060] In a specific embodiment, the braking device 12 can be a brake pedal that contacts the traveling wheel 11. When the chassis 1 needs to be limited, just step on the brake pedal, and the traveling wheel 11 will not be able to move forward. In another specific embodiment, the braking device includes a brake pad and a brake pedal. The brake pedal is drivingly connected to the brake pad. When the brake pedal is stepped on, the brake pad can be driven to move downward to contact the ground, so as to achieve the purpose of braking. When the brake pedal is lifted upward, the brake pad moves upward to脱离 the ground, and the chassis 1 can move freely again.
[0061] See Figure 4 and Figure 5In an embodiment of the present application, a medical magnetic field generator 4 system is also provided, which comprises a medical device 6 and the medical magnetic field generator mobile vehicle described above; the medical device 6 is provided with a slide rail 61, and the connecting device 25 of the medical magnetic field generator mobile vehicle is connected with the slide rail 61. After the medical magnetic field generator mobile vehicle is connected with the medical device 6, the medical magnetic field generator mobile vehicle can act in conjunction with the medical device 6. In addition, the medical magnetic field generator mobile vehicle is slidably arranged on the medical device 6, which can also ensure the stability of the medical magnetic field generator mobile vehicle.
[0062] The medical device 6 includes, but is not limited to, a surgical bed, a sickbed, a transfer bed, a surgical device, etc.
[0063] Taking the medical device 6 as a surgical bed as an example, referring to Figure 5 , the surgical bed comprises a moving frame and a bed surface, and at least one slide rail 61 is arranged at the edge side of the bed surface, and the arrangement direction of the slide rail 61 is the same as the length direction of the bed surface. The medical magnetic field generator mobile vehicle is connected with the slide rail 61 through the connecting device 25, and the medical magnetic field generator mobile vehicle can slide along the slide rail 61 to the front end or the rear end of the bed surface to meet the needs of different surgical scenarios.
[0064] Further, in the technical solution of the present application, the slide rail 61 can be arranged on one side of the bed surface, or the slide rails 61 can be arranged on both sides of the bed surface. One medical magnetic field generator mobile vehicle can be connected with any one of the slide rails 61, or multiple medical magnetic field generator mobile vehicles can be connected with different slide rails 61. In addition, the slide rails 61 can also be arranged around the bed surface, and the medical magnetic field generator mobile vehicle can be connected with any one of the slide rails 61.
[0065] In summary, the magnetic field generator is arranged on the movable chassis, the support assembly is connected with the lifting assembly through the first locking device, and the magnetic field generator is connected with the support assembly through the second locking device. After the first locking device and the second locking device are switched to the unlocked state, the magnetic field generator is decoupled from the lifting assembly, and the position of the magnetic field generator can be freely moved and flexibly adjusted. After the first locking device and the second locking device are switched to the locked state, the position of the magnetic field generator is fixed. The magnetic field generator has more operation freedom, which can meet the needs of different surgical scenarios and provide doctors with more ideal operation angles, thereby increasing the operation flexibility of the surgery.
