Description

Technical Field

[0001] The invention belongs to the field of medical particle accelerator manufacturing, and in particular relates to a non-rotating frame of a medical particle accelerator. Background Art

[0002] Medical particle accelerators are used in biomedical applications for radiotherapy of tumors. Charged particle accelerators are electromagnetic devices that artificially accelerate various types of charged particles to higher energies using electric fields of varying configurations. They are often referred to as "particle accelerators." To energize charged particles, an accelerating electric field is necessary. Accelerators are categorized into various types based on the type of accelerated particles, the type of accelerating electric field, and the trajectory followed during the particle acceleration process.

[0003] Currently, a Chinese utility model with publication number CN109876307A discloses a medical linear accelerator frame, comprising a fixed bracket, a rotating bracket, a gear rotation positioning device, and a harness drag chain mechanism. The rotating bracket is rotationally connected to the fixed bracket via the gear rotation positioning device, and the harness is connected to the rotating bracket via the harness drag chain mechanism. The rotating bracket is provided with a treatment head mounting bracket, and the harness is connected to the treatment head mounted on the treatment head mounting bracket via the harness drag chain mechanism. By providing the fixed bracket, rotating bracket, gear rotation positioning device, and harness drag chain mechanism, the gear rotation positioning device ensures rapid rotational positioning of the medical linear accelerator, effectively improving positioning accuracy and rotational rigidity. The harness drag chain mechanism further ensures rapid rotational positioning of the medical linear accelerator while providing power and data transmission for the accelerator and effectively protecting the harness.

[0004] During radiotherapy, patients must be precisely positioned to ensure that the lesion receives a sufficiently high radiation dose while minimizing damage to normal tissue. Existing medical particle accelerators typically install a particle accelerator drum within a non-rotating frame. Because the drum needs to rotate during operation, it is often accompanied by a certain amount of noise and vibration, which can affect the patient lying on the treatment bed. Furthermore, the drum needs to be braked at certain positions to allow treatment from different angles. However, existing medical particle accelerators cannot fully brake the drum due to its inertia, causing it to unexpectedly shift, affecting the precise positioning of the particle beam and causing deviations in the beam's position. Summary of the Invention

[0005] The present invention aims to provide a medical particle accelerator without a rotating frame, which has the advantages of reducing noise and vibration during operation of the medical particle accelerator, improving the braking effect of the medical particle accelerator, and reducing the function of accidental displacement of the particle acceleration drum due to inertia.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a medical particle accelerator without a rotating frame, comprising a protective housing, a support frame disposed within the protective housing, a noise reduction mechanism disposed between the protective housing and the support frame, a roller mounting shaft welded to one side of the interior of the protective housing, a particle accelerating roller rotatably connected to the surface of the roller mounting shaft via a bearing, a groove disposed within the support frame, a braking mechanism disposed within the groove for use with the particle accelerating roller, and a drive mechanism disposed on the other side of the interior of the protective housing for use with the particle accelerating roller.

[0007] The above technical solution employs multiple noise reduction mechanisms disposed between the protective housing and the support frame, thereby transmitting vibrations of the particle accelerator drum to the support frame during operation. The support frame then transmits the vibrations to the noise reduction mechanisms, which then dampen the vibrations. This effectively prevents the particle accelerator drum from contacting or colliding with other objects during operation. This also reduces the vibrations of the protective housing caused by the particle accelerator drum, thereby reducing the noise and vibrations of the medical particle accelerator during operation, thereby minimizing the impact on patients lying on the treatment bed and improving the stability of the medical particle accelerator. Multiple braking mechanisms are disposed between the support frame and the particle accelerator drum. When the particle accelerator drum rotates to a desired position, the braking mechanisms can be controlled to limit the position of the particle accelerator drum, while the multiple braking mechanisms simultaneously press the brake baffles against the surface of the particle accelerator drum. The setting in which the brake baffle generates a mutual force to press the particle acceleration drum can improve the braking effect of the medical particle accelerator and reduce the accidental displacement of the particle acceleration drum due to inertia, thereby effectively improving the accuracy of particle beam positioning, reducing the deviation of particle beam positioning, and improving the treatment effect of the medical particle accelerator.

[0008] The present invention is further configured such that the noise reduction mechanism includes a first connecting rod welded to the surface of the supporting frame, a cavity is opened inside the first connecting rod, a second connecting rod welded to the protective casing is arranged inside the cavity, and a noise reduction spring is fixedly connected between the second connecting rod and the first connecting rod via a spring fixing member.

[0009] By adopting the above technical solution, the noise and vibration of the medical particle accelerator during operation can be effectively reduced by providing a noise reduction mechanism.

[0010] The present invention is further configured such that the braking mechanism includes a hydraulic rod fixedly mounted inside the groove, a braking baffle is welded to the output end of the hydraulic rod, and a limiting baffle is welded to one side of the braking baffle in sliding connection with the particle acceleration drum.

[0011] By adopting the above technical solution, the braking effect of the medical particle accelerator can be effectively improved by providing a braking mechanism, and the accidental displacement of the particle acceleration drum due to inertia can be reduced.

[0012] The present invention is further configured as follows: the drive mechanism includes a drive motor fixedly mounted on the other side of the protective casing; the output end of the drive motor is bolted to a first transmission pulley via a coupling; the other side of the support frame is rotatably connected to a transmission gear; the side of the transmission gear away from the support frame is fixedly connected to a second transmission pulley; the surfaces of the first transmission pulley and the second transmission pulley are both sleeved with transmission belts; and a tooth groove meshing with the transmission gear is provided on one side of the surface of the particle acceleration drum.

[0013] The above technical solution is adopted: the first transmission pulley is driven to rotate by the driving motor, and then the first transmission pulley can drive the second transmission pulley to rotate in coordination with the transmission belt, and then the transmission gear is driven to rotate by the second transmission pulley, so that the transmission gear and the tooth groove are engaged, thereby driving the particle acceleration drum to rotate on the surface of the drum mounting shaft.

[0014] The present invention is further configured such that a sealing sleeve slidably connected to the second connecting rod is bonded to the interior of the first connecting rod, and a spring limit block used in conjunction with a noise reduction spring is welded between the first connecting rod and the second connecting rod.

[0015] The above technical solution is adopted: by setting a spring limit block, the elasticity of the noise reduction spring can be limited, and by setting a sealing sleeve, the first connecting rod can be sealed, so that the second connecting rod can slide in the inner ring of the sealing sleeve, reducing the leakage of gas inside the cavity.

[0016] The present invention is further configured such that a non-slip pad used in conjunction with the particle acceleration drum is bonded to the side of the brake baffle away from the hydraulic rod.

[0017] The above technical solution can be used to increase the friction between the brake baffle and the surface of the particle acceleration drum when the hydraulic rod drives the brake baffle to press down to brake the particle acceleration drum, thereby improving the braking effect of the braking mechanism.

[0018] The present invention is further configured such that the front of the protective housing is rotatably connected to a connecting ring arm bolted to the particle acceleration drum, and the top of the front of the connecting ring arm is fixedly connected to a particle beam emission head used in conjunction with the particle acceleration drum.

[0019] The above technical solution is adopted: the particle acceleration drum drives the connecting ring arm, so that the particle beam emission head can rotate along with the particle acceleration drum, so that the particle beam emission head can treat the patient from different angles.

[0020] The present invention is further configured such that a vertical laser emission port is fixedly mounted on the bottom of the particle beam emission head, and a vertical laser calibration arm used in conjunction with the vertical laser emission port is bolted to the bottom of the front side of the connecting ring arm.

[0021] By adopting the above technical solution, the laser beam is emitted through the vertical laser emission port and forms a vertical laser beam with the vertical laser calibration arm, thereby facilitating the positioning of the particle beam.

[0022] The present invention is further configured such that horizontal laser calibration arms are bolted to both sides of the front face of the connecting ring arm, and a horizontal laser emitting port for use with a vertical laser emitting port is fixedly installed inside the horizontal laser calibration arm.

[0023] The above technical solution is adopted: the laser beam is emitted through the horizontal laser emission port and forms a horizontal laser beam with the horizontal laser calibration arm, so that it forms a laser intersection with the vertical laser beam, so that the particle beam can be accurately positioned to a certain place inside the human body, so that the medical particle accelerator can accurately treat patients.

[0024] The present invention is further configured such that the support frame is made of high-strength stainless steel, and the surface of the support frame is coated with an anti-radiation coating.

[0025] The above technical solution: by setting the support frame to high-strength stainless steel material, the particle acceleration drum can be protected while being able to reduce vibration and noise and quickly brake the particle acceleration drum, thereby reducing damage to the particle acceleration drum caused by external impact and extending the service life of the medical particle accelerator. At the same time, the anti-radiation coating can reduce the damage caused by the particle accelerator to the patient's body.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The present invention provides multiple noise reduction mechanisms between the protective housing and the support frame, thereby transmitting vibrations of the particle accelerator drum to the support frame during operation. The support frame then transmits the vibrations to the noise reduction mechanisms for vibration reduction, effectively preventing the particle accelerator drum from contacting or colliding with other objects during operation. Furthermore, the vibrations of the protective housing caused by the particle accelerator drum can be reduced, thereby reducing noise and vibrations during operation of the medical particle accelerator, thereby minimizing the impact of the operation of the medical particle accelerator on the patient lying on the treatment bed and improving the stability of the medical particle accelerator.

[0028] 2. The present invention provides multiple braking mechanisms between the support frame and the particle accelerator drum. When the particle accelerator drum rotates to a desired position, the braking mechanisms can be controlled to brake and limit the drum. Simultaneously, the multiple braking mechanisms press the brake baffles against the surface of the particle accelerator drum. This configuration allows the brake baffles to generate a mutual force to press the particle accelerator drum, thereby improving the braking effect of the medical particle accelerator and reducing accidental displacement of the particle accelerator drum due to inertia. This effectively improves the accuracy of particle beam positioning, reduces deviation in particle beam positioning, and enhances the therapeutic effect of the medical particle accelerator.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] refer to Figure 2 、 Figure 3 、 Figure 5 A medical particle accelerator non-rotating frame includes a protective shell 1, a supporting frame 2 is arranged inside the protective shell 1, a noise reduction mechanism 3 is arranged between the protective shell 1 and the supporting frame 2, a roller mounting shaft 7 is welded on one side of the interior of the protective shell 1, and a particle acceleration roller 4 is rotatably connected to the surface of the roller mounting shaft 7 through a bearing. By arranging multiple noise reduction mechanisms 3 between the protective shell 1 and the supporting frame 2, the shaking of the particle acceleration roller 4 can be transmitted to the supporting frame 2 during operation, and the supporting frame 2 transmits the shaking to the noise reduction mechanism 3 to reduce the vibration of the particle acceleration roller 4 during operation, so that the particle acceleration roller 4 can effectively avoid contact and collision with other objects during operation, that is, at the same time, the shaking of the protective shell 1 caused by the particle acceleration roller 4 can be reduced, thereby achieving the effect of reducing noise and vibration during operation of the medical particle accelerator, thereby reducing the impact of the medical particle accelerator on the patient lying on the treatment bed during operation, and improving the stability of the medical particle accelerator.

[0039] refer to Figure 5 The noise reduction mechanism 3 includes a first connecting rod 301 welded to the surface of the support frame 2. A cavity 303 is defined inside the first connecting rod 301. A second connecting rod 302 welded to the protective housing 1 is disposed inside the cavity 303. A noise reduction spring 304 is fixedly connected between the second connecting rod 302 and the first connecting rod 301 via a spring fixing member. By providing the noise reduction mechanism 3, the noise and vibration during the operation of the medical particle accelerator can be effectively reduced.

[0040] refer to Figure 5 A sealing sleeve 306 is bonded to the inside of the first connecting rod 301 and is slidably connected to the second connecting rod 302. A spring limit block 305 used in conjunction with the noise reduction spring 304 is welded between the first connecting rod 301 and the second connecting rod 302. By setting the spring limit block 305, the spring movement of the noise reduction spring 304 can be limited. By setting the sealing sleeve 306, the first connecting rod 301 can be sealed, so that the second connecting rod 302 can slide on the inner ring of the sealing sleeve 306, thereby reducing the leakage of gas inside the cavity 303.

[0041] refer to Figure 2 、 Figure 3 、 Figure 4 The support frame 2 is made of high-strength stainless steel, and the surface of the support frame 2 is coated with an anti-radiation coating. By setting the support frame 2 to high-strength stainless steel, the particle acceleration drum 4 can be shock-absorbing, noise-reducing and quickly braked, and the particle acceleration drum 4 can also be protected, thereby reducing the damage to the particle acceleration drum 4 caused by external force impact, thereby increasing the service life of the medical particle accelerator. At the same time, the anti-radiation coating can reduce the harm of the particle accelerator to the patient's body.

[0042] Brief description of the usage process: When it is necessary to reduce the noise and vibration during the operation of the medical particle accelerator, first, the driving mechanism 8 is turned on to drive the particle acceleration drum 4 to rotate inside the support frame 2, and then the support frame 2 is shaken to cause the second connecting rod 302 to slide and shrink inside the first connecting rod 301, so that it squeezes the air inside the cavity 303 according to the amplitude of the shaking of the support frame 2 and shrinks the noise reduction spring 304. Finally, the air pressure inside the cavity 303 expands and the noise reduction spring 304 rebounds to cause the second connecting rod 302 to slide and extend, so that the noise reduction mechanism 3 can effectively prevent the particle acceleration drum 4 from contacting and colliding with other objects during operation, thereby reducing noise, and at the same time, it can reduce the shaking of the protective shell 1 driven by the particle acceleration drum 4, thereby reducing vibration.

[0043] Example 2:

[0044] refer to Figure 2 、 Figure 4 、 Figure 6 A non-rotating frame of a medical particle accelerator includes a protective housing 1, a support frame 2 having a groove 6 formed therein, a brake mechanism 5 for use with a particle accelerator drum 4 disposed therein, and a drive mechanism 8 for use with the particle accelerator drum 4 disposed on the other side of the protective housing 1. Multiple brake mechanisms 5 are provided between the support frame 2 and the particle accelerator drum 4, so that when the particle accelerator drum 4 rotates to a desired position, the brake mechanisms 5 can be controlled to brake and limit the particle accelerator drum 4. Simultaneously, when the multiple brake mechanisms 5 press a brake baffle 504 against the surface of the particle accelerator drum 4, the brake baffle 504 can generate a mutual force to press the particle accelerator drum 4, thereby improving the braking effect of the medical particle accelerator and reducing accidental displacement of the particle accelerator drum due to inertia. This effectively improves the accuracy of particle beam positioning, reduces deviation in particle beam positioning, and enhances the therapeutic effect of the medical particle accelerator.

[0045] refer to Figure 4 、 Figure 6 The braking mechanism 5 includes a hydraulic rod 501 fixedly installed inside the groove 6. A braking baffle 504 is welded to the output end of the hydraulic rod 501. A limiting baffle 502 is welded to one side of the braking baffle 504 and is slidably connected to the particle acceleration drum 4. By setting the braking mechanism 5, the braking effect of the medical particle accelerator can be effectively improved, and the accidental displacement of the particle acceleration drum due to inertia can be reduced.

[0046] refer to Figure 3The driving mechanism 8 includes a driving motor 806 fixedly installed on the other side of the protective shell 1. The output end of the driving motor 806 is bolted to the first transmission pulley 801 through a coupling. The other side of the support frame 2 is rotatably connected to the transmission gear 804. The transmission gear 804 is fixedly connected to the second transmission pulley 803 on the side away from the support frame 2. The surfaces of the first transmission pulley 801 and the second transmission pulley 803 are both sleeved with a transmission belt 802. A tooth groove 805 meshing with the transmission gear 804 is provided on one side of the surface of the particle acceleration drum 4. The first transmission pulley 801 is driven to rotate by the driving motor 806, and then the first transmission pulley 801 can drive the second transmission pulley 803 to rotate by the coordinated operation of the transmission belt 802. Then, the transmission gear 804 is driven to rotate by the second transmission pulley 803, so that the transmission gear 804 is meshed with the tooth groove 805, thereby driving the particle acceleration drum 4 to rotate on the surface of the drum mounting shaft 7.

[0047] refer to Figure 6 The side of the brake baffle 504 away from the hydraulic rod 501 is bonded with an anti-slip pad 503 for use with the particle acceleration drum 4. The anti-slip pad 503 increases the frictional force between the brake baffle 504 and the surface of the particle acceleration drum 4 when the hydraulic rod 501 drives the brake baffle 504 downward to brake the particle acceleration drum 4, thereby improving the braking effect of the brake mechanism 5.

[0048] refer to Figure 1 The front of the protective housing 1 is rotatably connected to a connecting ring arm 9 bolted to the particle acceleration drum 4. The top of the front of the connecting ring arm 9 is fixedly connected to a particle beam emission head 10 used in conjunction with the particle acceleration drum 4. The connecting ring arm 9 is driven by the particle acceleration drum 4, so that the particle beam emission head 10 can rotate with the particle acceleration drum 4, so that the particle beam emission head 10 can treat the patient from different angles.

[0049] refer to Figure 1 A vertical laser emitting port 14 is fixedly installed at the bottom of the particle beam emitting head 10, and a vertical laser calibration arm 11 used in conjunction with the vertical laser emitting port 14 is bolted to the bottom of the front of the connecting ring arm 9. The laser beam is emitted through the vertical laser emitting port 14 and forms a vertical laser beam with the vertical laser calibration arm 11, which makes it easier to position the particle beam.

[0050] refer to Figure 1Horizontal laser calibration arms 12 are bolted to both sides of the front of the connecting ring arm 9. A horizontal laser emitting port 13 is fixedly installed inside the horizontal laser calibration arm 12 for use with the vertical laser emitting port 14. The laser beam is emitted through the horizontal laser emitting port 13 and forms a horizontal laser beam with the horizontal laser calibration arm 12, forming a laser intersection with the vertical laser beam, thereby accurately positioning the particle beam to a certain place inside the human body, so that the medical particle accelerator can accurately treat the patient.

[0051] Brief description of the usage process: When it is necessary to improve the braking effect of the medical particle accelerator and reduce accidental displacement of the particle accelerator drum due to inertia, the driving mechanism 8 is first activated to drive the particle accelerator drum 4 to rotate inside the support frame 2. The particle accelerator drum 4 then drives the particle beam to the desired position, causing the hydraulic rod 501 to push the brake baffle 504 toward the particle accelerator drum 4, thereby causing the limit baffle 502 to slide along one side of the particle accelerator drum 4 and press the brake baffle 504 against the surface of the particle accelerator drum 4. Because multiple braking mechanisms 5 are installed inside the support frame 2, when the multiple braking mechanisms 5 press the brake baffle 504 against the surface of the particle accelerator drum 4, the brake baffle 504 can generate a mutual force to press the particle accelerator drum 4, thereby effectively improving the braking effect of the braking mechanism 5 on the particle accelerator drum 4 and reducing accidental displacement of the particle accelerator drum 4.
