Description

Technical Field

[0001] This invention relates to the field of mechanical structure technology for medical linear accelerators, specifically to an elastic anti-collision linear accelerator suspension cylinder structure. Background Technology

[0002] Medical linear accelerators consist of multiple moving parts and devices. To avoid safety risks during operation, multiple motion limiting mechanisms are incorporated into their design.

[0003] Treatment beds are motion devices frequently used in medical linear accelerators, especially for ring linear accelerators. During treatment, the treatment bed board extends into the linear accelerator's suspension cylinder to place the lesion in the designated location for treatment.

[0004] During the process of the treatment bed entering the linear accelerator's suspension cylinder, there is a risk of collision between the bed board and the cylinder in the event of equipment failure or limit switch malfunction. To prevent equipment damage in the event of a collision, an anti-collision structure is required. Upon collision, the sensors on the anti-collision structure transmit a signal to the motion control system. After receiving the collision signal, the motion control system quickly stops the movement of the treatment bed.

[0005] Collision-avoidance structures for medical linear accelerators have been widely used in C-arm linear accelerators. The sensing devices mostly use contact sensors. Some linear accelerator manufacturers have applied this method to ring linear accelerators. However, since contact sensors can only sense when squeezed, they need to be placed at multiple locations in the circumferential direction of the linear accelerator suspension cylinder. Moreover, they only consider circumferential collisions of the linear accelerator suspension cylinder and do not consider axial collisions.

[0006] In addition, some manufacturers have adopted a structure that integrates the compression spring support of the linear accelerator suspension cylinder and the contact sensor. The compression spring must both bear the load and sense the impact of the collision, which brings many difficulties to the selection, installation and debugging of the compression spring.

[0007] In view of this, this invention patent is hereby proposed. Summary of the Invention

[0008] To solve the above-mentioned technical problems, the present invention provides an elastic anti-collision linear accelerator suspension cylinder structure, specifically, the following technical solution is adopted:

[0009] A flexible, collision-resistant linear accelerator suspension cylinder structure, comprising:

[0010] Suspended cylinder;

[0011] The front support plate is provided, and the front end of the suspended cylinder is suspended on the front support plate by a suspension assembly.

[0012] The collision feedback mechanism, mounted on the front support plate, includes an axial collision feedback mechanism for monitoring the axial offset when the suspended cylinder is subjected to an axial collision, and / or a circumferential collision feedback mechanism for monitoring the circumferential offset when the suspended cylinder is subjected to a circumferential collision.

[0013] As an optional embodiment of the present invention, the axial collision feedback mechanism includes an axial offset triggering component and an axial offset detection component. The axial offset triggering component is mounted on the suspension cylinder, and the axial offset detection component is mounted on the front support plate. The axial offset triggering component and the axial offset detection component are installed correspondingly.

[0014] When the suspended cylinder is subjected to an axial collision, it causes the axial offset triggering component to shift its position along the axial direction of the suspended cylinder. The axial offset detection component realizes axial anti-collision feedback monitoring of the suspended cylinder by detecting the positional offset of the axial offset triggering component.

[0015] As an optional embodiment of the present invention, the suspension assembly includes an elastic suspension member, a hanging ring, and a hanging ring base. The hanging ring base is fixed to the outer peripheral wall of the suspension cylinder, and the hanging ring is fixed to the hanging ring base.

[0017] In the initial state, the photoelectric signal emitted by the photoelectric signal transmitter passes through the photoelectric channel on the first shielding plate and is received by the photoelectric signal receiver. When the suspended cylinder is axially impacted and deflected, it causes the first shielding plate to move axially, the photoelectric channel deviates from the transmission path of the photoelectric signal, the photoelectric signal emitted by the photoelectric signal transmitter is blocked by the first shielding plate, and the photoelectric sensor emits a detection signal.

[0018] As an optional embodiment of the present invention, the circumferential collision feedback mechanism includes a circumferential offset linkage component, a circumferential offset triggering component, and a circumferential offset detection component. The circumferential offset linkage component is fixedly connected to the outer peripheral wall of the suspended cylinder. The circumferential offset triggering component is connected to the circumferential offset linkage component. The circumferential offset detection component is disposed on the front support plate. The circumferential offset triggering component is disposed corresponding to the circumferential offset detection component.

[0019] When the suspended cylinder is subjected to a circumferential collision, it causes the circumferential offset linkage component to shift its position in the circumferential direction of the suspended cylinder. The circumferential offset linkage component drives the circumferential offset triggering component to move. The circumferential offset detection component realizes circumferential anti-collision feedback monitoring of the suspended cylinder by detecting the position status of the circumferential offset triggering component.

[0020] As an optional embodiment of the present invention, the circumferential offset linkage component includes a crank, a slider, and a slide rail. The slide rail is mounted on the front support plate. One end of the crank is rotatably connected to the outer peripheral wall of the suspension cylinder, and the other end of the crank is rotatably connected to the slider. The slider is slidably disposed on the slide rail, and the circumferential offset triggering component is disposed on the slider.

[0021] As an optional embodiment of the present invention, circumferential offset detection components are respectively provided at both ends of the slide rail. The circumferential offset triggering component has a first trigger end and a second trigger end located on both sides of the slider. The first trigger end and the second trigger end are respectively provided for the circumferential offset detection components at both ends of the slide rail. When the suspended cylinder is subjected to circumferential collision and undergoes circumferential offset, it drives the slider of the circumferential offset linkage component to slide horizontally. During the horizontal sliding process of the slider, the first trigger end and the second trigger end of the circumferential offset triggering component trigger the corresponding circumferential offset detection component to generate a detection signal.

[0022] As an optional embodiment of the present invention, the circumferential offset triggering component is a second blocking plate, and the second blocking plates are respectively installed on the opposite side walls of the slider, and the two second blocking plates form a first triggering end and a second triggering end at both ends of the slider;

[0023] The circumferential offset detection component includes a first photoelectric sensor and a second photoelectric sensor disposed at both ends of the slide rail, wherein the first trigger end corresponds to the first photoelectric sensor and the second trigger end corresponds to the second photoelectric sensor.

[0024] As an optional embodiment of the present invention, the circumferential offset linkage component includes a spherical hinge, which is installed on the outer peripheral wall of the suspension cylinder, and one end of the crank is rotatably connected to the spherical hinge.

[0025] As an optional embodiment of the present invention, the front end of the suspended cylinder is suspended on the front support plate by a first suspension assembly and a second suspension assembly arranged symmetrically;

[0026] The axial collision feedback mechanism includes a first axial collision feedback mechanism corresponding to the first suspension assembly and a second axial collision feedback mechanism corresponding to the second suspension assembly;

[0027] The circumferential collision feedback mechanism includes a first circumferential collision feedback mechanism and a second circumferential collision feedback mechanism disposed on both sides of the front end opening of the suspended cylinder. The first circumferential collision feedback mechanism and the second circumferential collision feedback mechanism are arranged symmetrically about the vertical diameter of the front end opening of the suspended cylinder.

[0028] As an optional embodiment of the present invention, an elastic anti-collision linear accelerator suspension cylinder structure of the present invention includes a PCBA board and a motion control system. The axial collision detection component of the axial collision feedback mechanism and the circumferential collision detection component of the circumferential collision feedback mechanism are respectively communicatively connected to the PCBA board, and the PCBA board is communicatively connected to the motion control system.

[0029] The PCBA board supplies power to each axial and circumferential collision detection component. The PCBA board collects the detection signals from each axial and circumferential collision detection component and transmits the detection signals to the motion control system. When the motion control system determines that the suspended cylinder has been subjected to an axial or circumferential collision, it controls the motion device to stop.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] The present invention provides an elastic anti-collision linear accelerator suspension cylinder structure. By setting an axial collision feedback mechanism, axial anti-collision feedback monitoring can be achieved when the suspension cylinder is subjected to axial collision.

[0045] See Figures 1-4 As shown, this embodiment of an elastic anti-collision linear accelerator suspension cylinder structure includes:

[0046] Suspended cylinder 100;

[0047] The front support plate 201 is used to suspend the front end of the suspended cylinder 100 on the front support plate 201 via the suspension assembly 300.

[0048] The collision feedback mechanism, installed on the front support plate 201, includes an axial collision feedback mechanism 400 for monitoring the axial offset when the suspended cylinder is subjected to an axial collision, and / or a circumferential collision feedback mechanism 500 for monitoring the circumferential offset when the suspended cylinder is subjected to a circumferential collision.

[0049] This embodiment provides an elastic anti-collision linear accelerator suspension cylinder structure. By setting an axial collision feedback mechanism 400, axial anti-collision feedback monitoring can be achieved when the suspension cylinder 100 is subjected to an axial collision. The axial collision feedback mechanism 400 can send the detection signal to the motion control system of the linear accelerator to control the linear accelerator to stop moving, thereby avoiding equipment damage caused by the suspension cylinder 100 continuing to operate after being subjected to an axial collision.

[0050] This embodiment provides an elastic anti-collision linear accelerator suspension cylinder structure. By setting a circumferential collision feedback mechanism 500, circumferential anti-collision feedback monitoring can be achieved when the suspension cylinder 100 is subjected to a circumferential collision. The circumferential collision feedback mechanism 500 can send the detection signal to the motion control system of the linear accelerator to control the linear accelerator to stop moving, thereby avoiding equipment damage caused by the suspension cylinder 100 continuing to operate after being subjected to a circumferential collision.

[0051] Therefore, the elastic anti-collision linear accelerator suspension cylinder structure of the present invention can, according to the detection requirements, selectively provide an axial collision feedback mechanism 400 or a circumferential collision feedback mechanism 500, or simultaneously provide both axial collision feedback mechanism 400 and circumferential collision feedback mechanism 500. This comprehensively considers collisions that may occur in multiple directions of the suspension cylinder, including circumferential and axial collisions, achieving all-round collision monitoring of the suspension cylinder. The elastic anti-collision linear accelerator suspension cylinder structure of the present invention is simple in structure, easy to install, and easy to maintain, achieving collision feedback in multiple circumferential directions with a simple structure.

[0052] As an optional implementation of this embodiment, the axial collision feedback mechanism 400 of this embodiment includes an axial offset triggering component 401 and an axial offset detection component 402. The axial offset triggering component 401 is installed on the suspension cylinder 100, and the axial offset detection component 402 is installed on the front support plate 201. The axial offset triggering component 401 and the axial offset detection component 402 are installed correspondingly.

[0053] When the suspended cylinder 100 is subjected to an axial collision, the axial offset triggering component 401 is driven to shift its position along the axial direction of the suspended cylinder 100. The axial offset detection component 402 realizes axial anti-collision feedback monitoring of the suspended cylinder 100 by detecting the position offset of the axial offset triggering component 401.

[0054] See Figure 1 and Figure 2 As shown, as an optional implementation of this embodiment, the suspension assembly 300 of this embodiment includes an elastic suspension member 301, a hanging ring 302, and a hanging ring base 303. The hanging ring base 303 is fixed on the outer peripheral wall of the suspension cylinder 100, and the hanging ring 302 is fixed on the hanging ring base 303. One end of the elastic suspension member 301 is suspended on the front support plate 201, and the other end is suspended on the hanging ring 302. The axial offset triggering member 401 is fixedly installed on the hanging ring base 303, or the axial offset triggering member 401 is integrally formed with the hanging ring base 303.

[0055] In this embodiment, the axial offset triggering component 401 is integrally formed with the lifting ring base 303. The lifting ring base 303 has a first arm extending a certain length along the circumference of the suspension cylinder 100 and a second arm extending a certain length along the axial direction of the suspension cylinder 100 at the end of the first arm. The second arm extends to the position of the axial offset detection component 402. The second arm is the axial offset triggering component 401.

[0056] Alternatively, as an optional implementation of this embodiment, the axial offset triggering component 401 of this embodiment may be a separate component fixedly installed on the lifting ring base 303.

[0057] As an alternative implementation of this embodiment, the detection component 402 described in this embodiment is a photoelectric sensor, including a photoelectric signal transmitting end 402A and a photoelectric signal receiving end 402B arranged opposite to each other. The axial offset triggering component 401 is a first shielding plate disposed between the photoelectric signal transmitting end 402A and the photoelectric signal receiving end 402B. A photoelectric channel 401A for photoelectric signal transmission is opened on the first shielding plate.

[0058] In the initial state, the photoelectric signal emitted by the photoelectric signal transmitter 402A passes through the photoelectric channel 401A on the first shielding plate and is received by the photoelectric signal receiver 402B. When the suspended cylinder 100 is axially offset by a collision, it causes the first shielding plate to move axially, the photoelectric channel 401A deviates from the transmission path of the photoelectric signal, the photoelectric signal emitted by the photoelectric signal transmitter 402A is blocked by the first shielding plate, and the photoelectric sensor emits a detection signal.

[0059] This embodiment uses a photoelectric sensor to achieve axial anti-collision feedback monitoring of the suspended cylinder 100. Other monitoring methods, such as electromagnetic induction monitoring and micro-switch monitoring, can also be used by the axial collision feedback mechanism 400 in this embodiment.

[0060] See Figure 3 and Figure 4 As shown, the circumferential collision feedback mechanism 500 described in this embodiment includes a circumferential offset linkage component, a circumferential offset triggering component, and a circumferential offset detection component (707A, 707B). The circumferential offset linkage component is fixedly connected to the outer peripheral wall of the suspended cylinder. The circumferential offset triggering component is connected to the circumferential offset linkage component. The circumferential offset detection components (707A, 707B) are disposed on the front support plate 201, and the circumferential offset triggering component is disposed corresponding to the circumferential offset detection components (707A, 707B).

[0061] When the suspended cylinder 100 is subjected to a circumferential collision, the circumferential offset linkage component is driven to shift its position in the circumferential direction of the suspended cylinder 100. The circumferential offset linkage component drives the circumferential offset triggering component to move. The circumferential offset detection component (707A, 707B) realizes circumferential anti-collision feedback monitoring of the suspended cylinder 100 by detecting the position status of the circumferential offset triggering component.

[0062] As an optional implementation of this embodiment, the circumferential offset linkage component in this embodiment includes a crank 701, a slider 702, and a slide rail 703. The slide rail 703 is mounted on the front support plate 201. One end of the crank 701 is rotatably connected to the outer peripheral wall of the suspension cylinder 100, and the other end of the crank 701 is rotatably connected to the slider 702. The slider 702 is slidably disposed on the slide rail 703, and the circumferential offset triggering component is disposed on the slider 702.

[0063] In this embodiment, the circumferential offset linkage component employs a crank-slider mechanism. By converting the circumferential collision offset experienced by the suspended cylinder 100 into linear sliding of the slider 702, the circumferential offset triggering component, mounted on the slider 702, is driven to slide. The circumferential offset detection component detects the position of the circumferential offset triggering component to achieve circumferential anti-collision feedback monitoring of the suspended cylinder. This embodiment converts the uncertain offset motion of the suspended cylinder 100 under circumferential collision into the fixed linear sliding of the slider through the circumferential offset linkage component, thereby achieving offset monitoring of the suspended cylinder 100 under circumferential collision.

[0064] Furthermore, in this embodiment, circumferential offset detection components (707A, 707B) are respectively provided at both ends of the slide rail 703. The circumferential offset triggering component has a first triggering end 704A and a second triggering end 704B located on both sides of the slider 703. The first triggering end 704A and the second triggering end 704B are respectively provided corresponding to the circumferential offset detection components (707A, 707B) at both ends of the slide rail 703. When the suspended cylinder 100 is subjected to circumferential collision and undergoes circumferential offset, it drives the slider 702 of the circumferential offset linkage component to slide horizontally. During the horizontal sliding process of the slider 702, the first triggering end 704A and the second triggering end 704B of the circumferential offset triggering component trigger the corresponding circumferential offset detection components (707A, 707B) to generate detection signals.

[0065] As an optional implementation of this embodiment, the circumferential offset triggering component described in this embodiment is a second blocking plate. The second blocking plates are respectively installed on the opposite side walls of the slider 702, and the two second blocking plates form a first trigger end 704A and a second trigger end 704B at both ends of the slider 702.

[0066] The circumferential offset detection component described in this embodiment includes a first photoelectric sensor 707A and a second photoelectric sensor 707B disposed at both ends of the slide rail. The first trigger end 704A corresponds to the first photoelectric sensor 707A, and the second trigger end 704B corresponds to the second photoelectric sensor 707B.

[0067] When the suspended cylinder 100 is subjected to a circumferential collision, the crank-slider mechanism pushes the second blocking plate to move along the guide rail. When the second blocking plate is located in the middle of the photoelectric sensor, it blocks the infrared light between the photoelectric transmitter and the photoelectric receiver. The resulting trigger signal is transmitted to the motion control system of the linear accelerator, causing the motion device to stop moving.

[0068] In this embodiment, a first photoelectric sensor 707A and a second photoelectric sensor 707B are respectively set on both sides of the guide rail. At the same time, a first trigger end 704A and a second trigger end 704B are formed at both ends of the slider 702, so that the circumferential offset detection component can be triggered when the slider 702 moves in both directions of the guide rail.

[0069] As an optional implementation of this embodiment, the circumferential offset linkage component includes a spherical hinge 706, which is mounted on the outer circumferential wall of the suspension cylinder 100. One end of the crank 701 is rotatably connected to the spherical hinge 706. Thus, when the suspension cylinder 100 is displaced by collision in any circumferential direction, the displacement can be transmitted to the crank 701 via the spherical hinge 706, causing the crank 701 to move.

[0070] See Figure 3 As shown, in this embodiment, the front end of the suspended cylinder 100 is suspended on the front support plate 201 by a first suspension assembly and a second suspension assembly arranged symmetrically.

[0071] The axial collision feedback mechanism 500 includes a first axial collision feedback mechanism corresponding to the first suspension assembly and a second axial collision feedback mechanism corresponding to the second suspension assembly;

[0072] The circumferential collision feedback mechanism 500 includes a first circumferential collision feedback mechanism and a second circumferential collision feedback mechanism disposed on both sides of the front end opening of the suspended cylinder 100. The first circumferential collision feedback mechanism and the second circumferential collision feedback mechanism are arranged symmetrically about the vertical diameter of the front end opening of the suspended cylinder 100.

[0073] Thus, in this embodiment, the axial collision feedback mechanism 500 and the circumferential collision feedback mechanism 500 are symmetrically distributed on the outer periphery of the front end of the suspended cylinder 100, ensuring the reliability of the axial and circumferential collision monitoring of the suspended cylinder 100.

[0074] In this embodiment, the rear end of the suspended cylinder 100 is mounted on the rear support plate 202.

[0075] This embodiment provides an elastic anti-collision linear accelerator suspension cylinder structure, including a PCBA board 700 and a motion control system. The axial collision detection component of the axial collision feedback mechanism 400 and the circumferential collision detection component of the circumferential collision feedback mechanism 500 are respectively communicatively connected to the PCBA board 700, and the PCBA board 700 is communicatively connected to the motion control system.

[0076] The PCBA board supplies power to each axial and circumferential collision detection component. The PCBA board collects the detection signals from each axial and circumferential collision detection component and transmits the detection signals to the motion control system. When the motion control system determines that the suspended cylinder has been subjected to an axial or circumferential collision, it controls the motion device to stop.

[0077] For details, see Figure 5 As shown, the axial collision detection component of this embodiment includes two photoelectric sensors, and the circumferential collision detection component of this embodiment includes four photoelectric sensors. The six photoelectric sensors are connected in series to the PCBA board.

[0078] This embodiment presents an elastic anti-collision linear accelerator suspension cylinder structure, achieving integrated control. It employs multiple photoelectric sensors connected in series. When any photoelectric sensor in the circuit detects a collision with the suspension cylinder, the light-receiving side ( Figure 5 The current in the series circuit decreases sharply, triggering the protection loop of the motion control system, thereby stopping the motion of the equipment.

[0079] This embodiment presents an elastic anti-collision linear accelerator suspension cylinder structure with an integrated control design. The cables of the axial collision detection components and the circumferential collision detection components are gathered in one place through a PCBA board, making the cable arrangement more convenient and simpler. At the same time, it saves the power interface of the electrical cabinet, making management and maintenance easier.

[0080] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
