Fig. 1 is a schematic structural view of a C-arm according to some embodiments of the present application, and fig. 2 is a schematic structural view of another state of the C-arm according to some embodiments of the present application. The C-arm according to the embodiment of the present application will be described in detail with reference to fig. 1 and 2. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In the embodiment of the present application, as shown in fig. 1, the C-shaped arm 110 includes a connecting arm 1, a driving device 4, a first supporting arm 2, and a second supporting arm 3; the first support arm 2 is provided with a ray generator 120, and the second support arm 3 is provided with a ray detector 130; first support arm 2 and second support arm 3 all with linking arm 1 swing joint, drive arrangement 4 is used for driving first support arm 2 and the simultaneous movement of second support arm 3, and first support arm 2 and second support arm 3 move along linking arm 1's extending direction in opposite directions or back on the back mutually. As shown in fig. 1, the first support arm 2 and the second support arm 3 are respectively located at two ends of the connecting arm 1, and the combination of the first support arm 2, the second support arm 3 and the connecting arm 1 is in a C shape. It should be noted that the extending direction can be understood as the length direction of the connecting arm 1, i.e. the direction marked in fig. 1 and 2. By the movement of the first support arm 2 and the second support arm 3 on the connection arm 1, the relative distance of the ray generator 120 and the ray detector 130 can be adjusted. Fig. 2 is a schematic structural diagram illustrating another state after the first support arm 2 and the second support arm 3 are moved toward each other from the state illustrated in fig. 1 according to some embodiments of the present application. It should be noted that the radiation generator 120 may be understood as a device capable of emitting radiation (X-ray, gamma ray, electronic wire, etc.), and the radiation detector 130 may be understood as a device capable of receiving radiation emitted by the radiation generator 120, so that medical examination or treatment, etc. can be performed by the cooperation of the radiation generator 120 and the radiation detector 130. In some alternative embodiments, the connecting arm 1 may be provided with a sliding groove along the extending direction thereof, and the first supporting arm 2 and the second supporting arm 3 may be respectively provided with a sliding block capable of sliding along the sliding groove, so that the first supporting arm 2 and the second supporting arm 3 can move along the extending direction of the connecting arm 1.
In the application of the C-arm 110, a bearing mechanism of the C-arm 110 (e.g., a frame of an X-ray machine, a CT apparatus, or a linear accelerator) may be connected to a middle portion of the connecting arm 1 of the C-arm 110, and the C-arm 110 may move (e.g., rotate) relative to the bearing mechanism of the C-arm 110. Through setting up first support arm 2 and second support arm 3 and moving along the extending direction of linking arm 1 simultaneously in opposite directions or back-to-back, can reduce bearing of this C type arm 110's bearing mechanism (for example reduce the torque that C type arm applyed to bearing mechanism) at the in-process of first support arm 2 and second support arm 3 motion on linking arm 1, or reduce the change that bearing mechanism bore (for example reduce the change of C type arm focus) to guarantee that C type arm 110 and C type arm 110's bearing mechanism can work steadily, can increase C type arm or X-ray machine's life to a certain extent simultaneously.
In some embodiments, the speed of movement of the first support arm 2 along the connecting arm 1 and the speed of movement of the second support arm 3 along the connecting arm 1 may be set to be the same.
In some embodiments, the speed of movement of the first support arm 2 along the connecting arm 1 may be greater than the speed of movement of the second support arm 3 along the connecting arm 1. For example, the drive means may be configured such that the speed of movement of the first support arm 2 along the connecting arm 1 is greater than the speed of movement of the second support arm 3 along the connecting arm 1. It should be noted that, in practical applications, the weight of the ray generator 120 is often greater than that of the ray detector 130. For example, the weight of the radiation generator 120 may be 100 KG and 120KG, and the weight of the radiation detector 130 may be 30 KG to 40KG, so that the weight of the first support arm 2 and the components thereon is greater than the weight of the second support arm 3 and the components thereon. The general use of the C-arm 110 is: the first support arm 2 and the second support arm 3 are first positioned at both ends of the connection arm 1 (initial state), so that there is a large operation space between the ray generator 120 and the ray detector 130. The first support arm 2 and the second support arm 3 are then moved towards each other to adjust them into position. Since the weight of the radiation generator 120 is greater than that of the radiation detector 130, if the support arm is symmetrically installed around the rotation center of the C-arm, the center of gravity of the C-arm 110 deviates from the rotation axis of the central portion in the initial state more, and the torque applied to the support mechanism of the C-arm 110 is larger. By making the speed of the first support arm 2 greater than the speed of the second support arm 3, the center of gravity of the C-arm 110 can be brought closer to the rotation axis in the process of adjusting the distance between the first support arm 2 and the second support arm 3 from the initial state, and therefore the torque of the bearing mechanism of the C-arm 110 becomes smaller and the bearing of the bearing mechanism of the C-arm 110 also becomes smaller.
In some embodiments, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 to the speed of movement of the second support arm 3 along the connecting arm 1 may be any value greater than 1. For example, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 to the speed of movement of the second support arm 3 along the connecting arm 1 may be 2:1, 3:1, 5:1, etc. In some embodiments, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 to the speed of movement of the second support arm 3 along the connecting arm 1 may be equal to the ratio of the sum of the weight of the first support arm 2 and components thereon to the sum of the weight of the second support arm 3 and components thereon. For example, when the sum of the weight of the first support arm 2 and the components thereon is 120KG, and the sum of the weight of the second support arm 3 and the components thereon is 40KG, the ratio of the speed of the first support arm 2 moving along the connecting arm 1 to the speed of the second support arm 3 moving along the connecting arm 1 may be 3: 1. It should be noted that the sum of the weights of the first support arm 2 and the components thereon can be understood as the weight of the first support arm 2 itself plus the weight of all the devices and components disposed on the first support arm 2, and the sum of the weights of the second support arm 3 and the components thereon can be understood as the weight of the second support arm 3 itself plus the weight of all the devices and components disposed on the second support arm 3. In some alternative embodiments, when the weight of the first support arm 2 and the second support arm 3 are substantially the same, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 and the speed of movement of the second support arm 3 along the connecting arm 1 may be equal to the ratio of the weight of the radiation generator 120 to the weight of the radiation detector.
In some embodiments, the speed of movement of the first support arm 2 along the connecting arm 1 is less than the speed of movement of the second support arm 3 along the connecting arm 1. For example, the drive means may be configured such that the speed of movement of the first support arm 2 along the connecting arm 1 is less than the speed of movement of the second support arm 3 along the connecting arm 1. Since the weight of the first support arm 2 and the components thereon is greater than the weight of the second support arm 3 and the components thereon, with such an arrangement, in the process of movement of the first support arm 2 and the second support arm 3 along the extending direction of the connecting arm 1, the change in the position of the center of gravity of the C-shaped arm 110 is small with respect to the state where the first support arm 2 and the second support arm 3 are respectively located at both ends of the connecting arm 1. In some embodiments, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 to the speed of movement of the second support arm 3 along the connecting arm 1 may be any value less than 1. For example, the ratio of the speed of movement of the first support arm 2 along the connecting arm 1 to the speed of movement of the second support arm 3 along the connecting arm 1 may be 1:2, 1:3, 2:5, etc. For another example, the ratio of the speed of the first support arm 2 moving along the connecting arm 1 to the speed of the second support arm 3 moving along the connecting arm 1 may be the ratio of the weight of the radiation detector 130 to the weight of the radiation generator 120.
In some embodiments, the position of the center of gravity of the C-arm 110 remains unchanged during movement of the first support arm 2 and the second support arm 3 relative to the connecting arm 1. The person skilled in the art can specifically determine the speed of the first support arm 2 moving along the connecting arm 1 and the speed of the second support arm 3 moving along the connecting arm 1 according to the weight of the first support arm 2 and its upper component, the second support arm 3 and its upper component, the connecting arm 1, etc. of the C-shaped arm 110, so as to ensure that the position of the center of gravity of the C-shaped arm 110 remains unchanged. For example, the ratio of the speed at which the first support arm 2 moves along the connecting arm 1 to the speed at which the second support arm 3 moves along the connecting arm 1 is equal to the ratio of the sum of the weights of the second support arm 3 and the components thereon to the sum of the weights of the first support arm 2 and the components thereon. In this case, the position of the center of gravity of the C-arm 110 can be kept constant during the movement of the first support arm 2 and the second support arm 3 relative to the connecting arm 1. Specifically, when the total weight of the first support arm 2 and the components thereon is 120KG, and the total weight of the second support arm 3 and the components thereon is 40KG, the ratio of the speed of the first support arm 2 moving along the connecting arm 1 to the speed of the second support arm 3 moving along the connecting arm 1 is 1: 3. The gravity center position of the C-shaped arm 110 is kept unchanged by setting the ratio of the movement speeds of the first support arm 2 and the second support arm 3, so that the influence of the change of the gravity center position of the C-shaped arm 110 on the bearing of the structure of the C-shaped arm 110 and the bearing of the bearing mechanism of the C-shaped arm 110 can be no longer considered in the design and production processes of the C-shaped arm 110, and the difficulty in controlling the movement of the C-shaped arm 110 can be further reduced. In some alternative embodiments, when the C-arm is able to rotate on the bearing mechanism of the C-arm 110, the center of gravity of the C-arm may coincide with the axis of rotation to ease the bearing of the bearing mechanism of the C-arm 110. For example, the axis of rotation of the carrier of the C-arm 110 may be arranged to coincide with the center of gravity of the C-arm.
In some embodiments, the drive means comprise an electric motor, a worm, a first rack and a second rack, the electric motor being able to drive the worm in rotation about its axis, the axis of the worm being arranged along the extension direction of the connecting arm 1; the worm has first spiral section and second spiral section, and the direction of rotation of first spiral section and second spiral section is opposite, and first rack can cooperate and link to each other with first support arm 2 with first spiral section, and the second rack can cooperate and link to each other with second support arm 3 with second spiral section. The first and second racks are movable in opposite directions during rotation of the worm so that the first and second support arms 2, 3 are movable in opposite directions. In some embodiments, the worm is rotatably arranged on the connecting arm 1. In addition, the motor may be connected to the worm through a reducer. The first supporting arm 2 and the second supporting arm 3 are driven to move through the matching of the worm and the rack, and the device has the advantages of being large in transmission ratio, stable in transmission, low in noise and the like.
In some embodiments, the lead of the first thread segment and the lead of the second thread segment may be set to be the same, which may result in the first support arm 2 moving along the linking arm 1 at the same speed as the first support arm 2 moving along the linking arm 1. In other embodiments, the lead of the first helical section is different from the lead of the second helical section. For example, the lead of the first helical section may be set greater than the lead of the second helical section so that the speed of movement of the first support arm 2 along the linking arm 1 is greater than the speed of movement of the first support arm 2 along the linking arm 1. Or the lead of the first helical section may be set smaller than the lead of the second helical section so that the speed of movement of the first support arm 2 along the linking arm 1 is less than the speed of movement of the first support arm 2 along the linking arm 1. The person skilled in the art can specifically set the lead size of the first thread segment and the second thread segment according to the required speed ratio of the first support arm 2 to the second support arm 3, and the application is not limited thereto.
As shown in fig. 1 and 2, in some embodiments, the driving device 4 includes a motor, a lead screw 41, a first nut 42, and a second nut 43, the motor being capable of driving the lead screw 41 to rotate about its axis, the axis of the lead screw 41 being arranged along the extending direction of the connecting arm 1. The screw 41 has a first thread section and a second thread section, the thread directions of the first thread section and the second thread section are opposite, the first nut 42 can be matched with the first thread section and connected with the first support arm 2, and the second nut 43 can be matched with the second thread section and connected with the second support arm 3. The first nut 42 and the second nut 43 are movable in opposite directions during rotation of the lead screw 41, so that the first support arm 2 and the second support arm 3 are movable in opposite directions. In some embodiments, the lead screw 41 is rotatably provided on the connecting arm 1. In some embodiments, the motor may be coupled to the lead screw 41 through a speed reducer. In some embodiments, the electric machine may comprise a direct drive motor. The first support arm 2 and the second support arm 3 are driven to move through the matching of the lead screw 41 and the nut, the transmission efficiency and the transmission precision are high, and the distance between the ray generator 120 and the ray detector 130 can be conveniently adjusted.
In some embodiments, the lead of the first thread segment and the lead of the second thread segment may be set to be the same, which may result in the first support arm 2 moving along the linking arm 1 at the same speed as the first support arm 2 moving along the linking arm 1. In other embodiments, the lead of the first thread segment is different from the lead of the second thread segment. For example, the lead of the first thread segment may be arranged to be greater than the lead of the second thread segment such that when the first support arm 2 moves along the linking arm 1 at a greater speed than the first support arm 2 moves along the linking arm 1. Alternatively the lead of the first thread segment may be set smaller than the lead of the second thread segment so that the first support arm 2 moves along the linking arm 1 at a lower speed than the first support arm 2 moves along the linking arm 1.
In some embodiments, the driving device comprises a motor, a gear, a third rack and a fourth rack, the motor can drive the gear to rotate, the gear is rotatably connected to the connecting arm 1, the third rack and the fourth rack are both arranged along the extending direction of the connecting arm 1 and are meshed with the gear, the third rack is connected to the first supporting arm 2, and the fourth rack is connected to the second supporting arm 3. The third and fourth racks are respectively provided at both sides of the gear, and when the gear rotates, the third and fourth racks move in opposite directions, so that the first and second support arms 2 and 3 can move in opposite directions. The above-mentioned gear and rack cooperation drives the first support arm 2 and the second support arm 3 to move, and is suitable for the situation that the first support arm 2 and the second support arm 3 have the same moving speed. In some embodiments, a gear set may be used to drive in conjunction with the rack. For example, a gearwheel and a pinion can be arranged to rotate coaxially, or two gears with different modules can rotate coaxially, and the two gears are used to drive a third rack and a fourth rack to move respectively, so that the first support arm 2 and the second support arm 3 can move at different speeds. The gear rack transmission has the advantage of large bearing capacity, is suitable for the condition that equipment borne on the C-shaped arm 110 is heavy, has high transmission speed in the transmission mode, can realize the quick adjustment of the distance between the ray generator 120 and the ray detector 130, and is convenient for the quick proceeding of examination and treatment. In some alternative embodiments, the driving device may further include a belt transmission (such as a synchronous belt transmission), a chain transmission, and the like, which is not limited in this application.
In some embodiments, the first support arm 2, the second support arm 3 and the connecting arm 1 each have a hollow interior, and the drive means 4 is provided in the interior of the connecting arm 1. The inner cavity can be used for the wires or cables used by the equipment arranged on the first support arm 2 and the second support arm 3 to pass through, on the other hand, the weight of the C-shaped arm 110 can be reduced by arranging the inner cavity, and on the other hand, the use of the material of the C-shaped arm 110 can be reduced by arranging the inner cavity. It should be noted that the number of the inner cavities of the first support arm 2, the second support arm 3 and the connecting arm 1 may be one, or may be multiple (e.g. 2, 3, 4 or 6), and the multiple inner cavities may be communicated with each other. The number, arrangement, size and shape of the hollow cavities can be specifically set by those skilled in the art according to actual needs. For example, the cross-sectional shape of the lumen may be circular, square, polygonal, irregular, etc., and variations such as these are within the scope of the present application.
In the present application, the material of the first support arm 2 and the second support arm 3 may be provided as carbon fiber. For example, the first support arm 2 and/or the second support arm may be integrally formed from a carbon fibre material. In some embodiments, reinforcing ribs may be provided in both the first support arm 2 and the second support arm 3. The strengthening rib can further improve its structural strength on the basis of the wall thickness that does not increase first support arm 2 and second support arm 3, avoids the atress of first support arm 2 and second support arm 3 to warp to make first support arm 2 and second support arm 3 can support the equipment of setting above that better. It should be noted that the reinforcing ribs may be arranged in a strip shape, a grid shape, or the like, and a person skilled in the art may specifically design the shape of the reinforcing ribs as needed, which is not limited in this application. In some embodiments, stiffening ribs may also be provided in the connecting arm 1 in order to further enhance the structural strength of the C-arm 110. In other embodiments, the stiffener may be disposed on the outer surface of the C-shaped arm 110 (the first support arm 2, the second support arm 3, and/or the connecting arm 1). The purpose of the stiffener arrangement is mainly to increase the overall stiffness of the C-arm, so that a person skilled in the art can also arrange the stiffeners at other positions according to the actual needs, and can also increase (or decrease) the number of stiffeners reasonably according to the needs. In the above embodiments, the reinforcing rib may also be other structures for enhancing rigidity, such as a reinforcing plate, a reinforcing rib, and the like, and such a variation is still within the scope of the present application.
