Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202011468108.5, filed on December 14, 2020, and Chinese Patent Application No. 202111021712.8, filed on September 1, 2021, the contents of each of which are incorporated herein by reference. Technical Field

[0003] This manual relates to medical technology, particularly slip ring assemblies and / or medical systems. Background Technology

[0004] Existing medical systems are multimodal, comprising multiple medical devices (e.g., a treatment device, an imaging device, and multiple imaging devices of different modalities). The various components of such systems may be connected by cables, and the cabling can be complex. For example, an image-guided radiotherapy (IGRT) system includes a treatment unit and an imaging unit. The imaging device is used to visualize a specific target tissue (e.g., cancerous tissue) before, during, or after the treatment unit delivers radiation to the target tissue. In existing image-guided radiotherapy systems, the imaging device is connected to the treatment unit via cables. Therefore, it would be desirable to develop a system that allows for simple connection of multiple medical devices within the medical system. Summary of the Invention

However, structures that may perform the same or similar functions as the components listed above or mentioned elsewhere in this specification may be given different names than those in this specification.

[0062] In this specification, spatial reference terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., are used in a relative sense to indicate the directional or positional relationship between two or more elements, components, devices, or systems, based on the directional or positional relationships shown in the accompanying drawings, and are used only for convenience and simplicity of description, and do not indicate or imply that the elements, components, devices, or systems in this specification have a particular orientation when operating the disclosed system or a part thereof, or are constructed and operated in a particular orientation, and therefore should not be construed as limiting this specification.

[0063] It is understood that although the terms "first," "second," "third," etc., may be used herein to describe various elements, these elements should not be limited by these terms.

[0065] These and other features, characteristics, functions and operating methods of related structural elements, as well as component assembly and manufacturing economics, will become more apparent from the following description of the accompanying drawings, which form part of this application specification. However, it should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of this application. It should also be understood that the drawings are not drawn to scale.

[0066] One aspect of this specification relates to a slip ring assembly. The slip ring assembly may include a first slip ring, a second slip ring, and a transmission component located between the first and second slip rings. The transmission component is operatively connected to the first and second slip rings and configured to transmit data from the first and second slip rings.

[0067] In some embodiments, the slip ring assembly can be configured in a medical system. The slip ring assembly can be configured to power at least one component of the medical system (e.g., an imaging component, a treatment component) and / or facilitate data transmission, thereby eliminating the need for cables, as is common in existing medical systems, to power and / or transmit data to different medical components (e.g., imaging and treatment components, imaging components of different modalities).

[0068] Furthermore, since the use of cables and their complex wiring to connect devices or components of the medical system for power supply and / or data transmission is eliminated, slip ring assemblies can reduce the axial dimension of the medical system or a portion thereof (e.g., as...). Figure 1 Y direction shown).

[0069] Furthermore, by allowing the first and second slip rings to share the transmission component, the slip ring assembly can also reduce the radial direction along the medical system (e.g., as shown in the image). Figure 1 The dimensions (or a portion thereof) of the imaging and / or therapeutic source in the z-direction (as shown) are adjusted to bring the imaging and / or therapeutic source closer to the object (e.g., the patient) in the medical system. By reducing the path distance, or a portion thereof, that the imaging and / or therapeutic medium (e.g., X-rays) traverses before impacting the object, diffusion of the imaging and / or therapeutic medium along the path can be reduced, thereby improving the delivery accuracy of the imaging and / or therapeutic medium and / or the image accuracy and / or therapeutic effect based on the imaging or therapeutic medium.

[0070] In some embodiments, the transmission component may include a static ring. The static ring may be disposed between a first slip ring and a second slip ring, thereby improving the reliability of data transmission between the first slip ring (or the second slip ring) and the static ring. Furthermore, the slip ring assembly may be configured simultaneously for both contact and non-contact data transmission modes. The accuracy of data transmitted in either data transmission mode can be verified by data transmitted in the other data transmission mode. When one of the two data transmission modes fails to function properly, data transmission can proceed in the other data transmission mode, further improving the reliability of data transmission via the slip ring assembly.

At least one component located on the first frame can rotate with the first frame. For example, at least one imaging source and at least one imaging detector can rotate with the first frame. The second frame can rotate along a second axis (e.g., along a second axis). Figure 4 (B) Rotation. At least one component located on the second frame may rotate with the second frame. For example, at least a portion of the treatment head (such as a treatment source) may rotate with the second frame. In some embodiments, each of the first and second frames may be a ring structure. The first axis or the second axis may be the axial direction of the ring structure.

[0087] In some embodiments, the radius of the second frame may be greater than the radius of the first frame. It should be noted that, in this specification, the “radius” of a ring structure (such as a frame, a ring (such as a slip ring, a static ring)) may refer to either the inner radius or the outer radius of the ring structure.

[0088] In some embodiments, the first axis may intersect or (substantially) coincide with the second axis. For example, the intersection of the first and second axes may (substantially) coincide with the isocenter of the medical device 110 (e.g., the intersection of the rotation axes of the first or second gantry, the treatment assembly, and the imaging assembly). As used herein, "substantially," when used to describe a feature, means a deviation from that feature that is below a threshold. For example, the intersection of the first and second axes substantially coinciding with the isocenter may indicate that the distance between the isocenter of the medical device 110 and the intersection of the first and second axes is below a threshold, such as 1 mm, 2 mm, 3 mm, etc. In some embodiments, the first axis may (substantially) be parallel to the second axis. As used herein, "substantially" means that the angle between the first and second axes is below a threshold, such as 1 degree, 5 degrees, 10 degrees, etc. In this case, imaging quality and treatment quality can be guaranteed. Furthermore, the target volume of the object can be imaged and treated in one location, thereby avoiding the need to move the object or the bed supporting the object during imaging and / or treatment, and avoiding the need for positional adjustments relative to the treatment plan of the object.

[0089] In some embodiments, the medical device 110 may include a first bearing and a second bearing different from the first bearing. A first frame may be operatively connected to a second frame via the first bearing. The second frame may be operatively connected to a fixed frame via the second bearing. In some embodiments, a fixed portion (e.g., a stator) of the first bearing may be attached to the second frame, while a rotating portion (e.g., a rotor) of the first bearing may be attached to the first frame. A fixed portion (e.g., a stator) of the second bearing may be attached to the fixed frame, and a rotating portion (e.g., a rotor) of the second bearing may be attached to the second frame.

[0090] In some embodiments, the first or second bearing may be an electromagnetic bearing, a mechanical bearing, or the like. For example, a mechanical bearing may include a sliding bearing, a rolling bearing, or the like. Electromagnetic bearings can be used between components that rotate at high speeds relative to each other. By using electromagnetic bearings, there may be no mechanical contact (and therefore no friction) between the first and second frames or between the second frame and the fixed frame, thereby extending the service life of the frame.

[0091] In some embodiments, the medical device 110 may include a first drive component and a first transmission component. In some embodiments, the first drive component may include an electric motor, engine, etc. The first transmission component may include a belt-driven transmission assembly, a chain-driven transmission assembly, a gear-driven transmission assembly, etc. In some embodiments, the first drive component may drive the rotating portion of the first bearing via the first transmission component, thereby driving the first frame and the first slip ring to rotate relative to a fixed frame. In some embodiments, the first drive component may directly drive the rotating portion of the first bearing to rotate, thereby avoiding the need for a first transmission component. For example, the first drive component may include a direct drive rotary (DDR) motor operatively connected to the first bearing. As another example, the first drive component may include a servo motor, stepper motor, etc.

[0092] In some embodiments, the medical device 110 may include a second drive component different from the first drive component and a second transmission component different from the first transmission component. In some embodiments, the second drive component may drive the rotating portion of the second bearing through the second transmission component, thereby driving the second frame and the second slip ring to rotate relative to the fixed frame. In some embodiments, the second drive component may directly drive the rotating portion of the second bearing to rotate, thereby avoiding the need for a second transmission component. It should be noted that the structures of the second drive component and the second transmission component may be the same as or similar to the structures of the first drive component and the first transmission component, respectively, and will not be described in detail here.

[0093] In some embodiments, the first rack may be configured to rotate independently of the second rack. In some embodiments, the first rack and the second rack may be configured to rotate synchronously. In some embodiments, the medical device 110 may include a locking mechanism. In some embodiments, the locking mechanism may be located between the first rack and the second rack. In some embodiments, the locking mechanism may be located on the first rack. In some embodiments, the locking mechanism may be located on the second rack. In some embodiments, the locking mechanism may be located on both the first rack and the second rack.

[0094] In some embodiments, the locking mechanism may be configured to lock or unlock the first and second racks. When the first and second racks are locked, they can rotate synchronously. In some embodiments, the first and second racks can rotate synchronously relative to a fixed rack. When the first and second racks are unlocked, the first rack can rotate independently of the second rack. For example, the first rack can rotate when the second rack is stationary relative to the fixed rack. As another example, the second rack can rotate when the first rack is stationary relative to the fixed rack.

[0095] In some embodiments, the first drive component may be configured to drive the first transmission component to move the first bearing, and / or the second drive component may be configured to drive the second transmission component to move the second bearing, in response to the first frame and the second frame being locked by a locking mechanism, such that the second frame, the second slip ring, the first frame and the first slip ring can rotate synchronously relative to the fixed frame.

[0096] In some embodiments, the locking mechanism may include an electromagnetic braking device. This electromagnetic braking device may include an electromagnetic bearing (e.g., a first bearing) and a drive component (e.g., an electric motor, engine). The drive component may be configured to lock or unlock the rotating and stationary portions of the electromagnetic bearing, thereby locking or unlocking the first and second frames. In this configuration, no transmission component is required for locking or unlocking the first and second frames.

[0097] In some embodiments, the locking mechanism may include at least one keyhole and at least one latch. The at least one keyhole may be located on one of the first frame and the second frame, while the at least one latch may be located on the other of the first frame and the second frame. In some embodiments, the at least one keyhole may be circumferentially positioned or distributed on the surface of the first frame. The at least one latch may be correspondingly positioned or distributed on the surface of the second frame such that the at least one latch can be inserted into the at least one keyhole to lock the first frame and the second frame. For example, the locking mechanism may include a plurality of keyholes circumferentially distributed on the surface of the first frame and a plurality of latches circumferentially distributed on the surface of the second frame, each of the plurality of latches being inserted into one of the plurality of keyholes, thereby locking the first frame and the second frame in different positions. As another example, each of the plurality of latches may be inserted into a different keyhole among the plurality of keyholes, such that the position of the first frame relative to the second frame is different.

[0098] In some embodiments, the first and second gantry may be unlocked before the treatment head fires a treatment beam toward a region of the object (e.g., the area to be treated) to perform radiation therapy on the object. The first gantry may rotate independently of the second gantry to image the object or a portion thereof, such as the target volume of the object. In this case, the first gantry may rotate at a relatively high speed (e.g., 120 r / min) unaffected by the second gantry, thereby completing imaging in a short time, reducing imaging artifacts, and / or improving image quality. In some embodiments, after imaging of the object is completed, the first and second gantry may be locked by a locking mechanism. The treatment head may then fire a treatment beam to treat the target volume of the object. The first gantry and imaging assembly, or portions thereof attached to the first gantry, may be configured with openings through which the treatment beam can pass before traveling toward the object. In some embodiments, after imaging of the object is completed, the first gantry may continue to rotate independently of the second gantry, that is, the first gantry rotates relative to the second gantry during radiotherapy. The object may be further imaged during radiotherapy, and the imaging results can be used to detect radiotherapy.

[0099] In some embodiments, the medical device 110 may include a patient support 113. The patient support 113 may be configured to support an object. The patient support 113 may have multiple (e.g., six) degrees of freedom, such as three translational degrees of freedom along three coordinate directions (i.e., x, y, and z directions) and three rotational degrees of freedom about the three coordinate directions. Accordingly, the patient support 113 may move the object along one direction in a three-dimensional coordinate system. As an example only, the patient support 113 may move along... Figure 1 The object is moved into the field of view of medical device 110 by the y-direction.

[0100] In some embodiments, the object may be biological or non-biological. By way of example only, the object may include a patient, an artificial object, etc. As another example, the object may include a specific part, organ, and / or tissue of a patient.
