[0002] Radiotherapy, also known as radiation therapy, is the treatment of malignant tumors and some benign diseases using one or more types of ionizing radiation. Radiotherapy uses ionizing radiation, one of the three major cancer treatments. It irradiates tumors with rays of various energies to inhibit and kill cancer cells. During radiotherapy, the patient lies on a treatment board and the radiotherapy device is used to deliver radiation to the treatment area. However, during clinical radiotherapy, radiation will inevitably have a certain impact on normal human tissues, causing certain radiation reactions and damage. Therefore, shielding devices are needed to shield non-radiotherapy areas during treatment.

[0003] Current shielding devices generally cover the patient's body directly with a shielding plate. The shielding plate and the patient's skin are not tightly fitted together, which may cause some radiation rays to flow through the gap to the non-radiotherapy area, increasing the chance of harm to the patient.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. In the present invention, the telescopic mechanism is extended and drives the connecting seat and the clamping movable mechanism to move toward the side close to the patient, so that the two clamping movable mechanisms move to both sides of the patient and stop moving, and the clamping movable mechanism drives the part of the shielding member located above the patient to move toward both sides of the patient, so that the shielding member is tightly attached to the patient's body, shielding the patient's body, and reducing the chance of damage to the non-radiotherapy area during radiotherapy; the telescopic mechanism is shortened by the controller, and the clamping movable mechanism automatically relaxes part of the shielding member, so that the shielding member can move relative to the clamping movable mechanism, and then the sliding seat is driven to slide by the No. 5 power mechanism, which drives the cover to slide and drives the shielding member to move longitudinally, so that the clamping movable mechanism moves to the patient's body. On both sides, the shielding piece is tightly attached to the patient's body through the clamping moving mechanism to complete the adjustment of the longitudinal position of the radiotherapy port; one clamping moving mechanism is first moved to drive the part of the shielding piece located on the patient's side to move between the two clamping moving mechanisms, so that the shielding piece on the patient becomes loose, and then the other clamping moving mechanism is moved to drive the part of the shielding piece located above the patient to move to the side of the patient to adjust the lateral position of the radiotherapy port; after the radiotherapy is completed, before the cover is rotated upward, the telescopic mechanism is shortened to the shortest distance, at this time the clamping moving mechanism is away from the patient, and the part of the shielding piece is automatically relaxed, so that the cover can drive the telescopic mechanism, the clamping moving mechanism, the shielding piece, etc. to rotate upward.

[0036] 2. In the present invention, when the telescopic mechanism extends and drives the connecting seat and the clamping movable mechanism to move toward the patient side, the connecting assembly drives the connecting member to slide, so that the distance between the connecting member and the connecting seat becomes the maximum, and the distance between the No. 2 reel and the No. 1 reel is minimized. At this time, the No. 2 reel and the No. 1 reel are respectively squeezed on both sides of the local part of the shielding member to clamp the local part of the shielding member; when the telescopic mechanism shortens and drives the connecting seat and the clamping movable mechanism to move away from the patient side, the connecting assembly drives the connecting member to slide, reducing the distance between the connecting member and the connecting seat, so that the distance between the connecting member and the connecting seat becomes the minimum, and the distance between the No. 2 reel and the No. 1 reel is maximized, and the local part of the shielding member is relaxed. In the initial stage when the clamping movable mechanism is away from the patient's body, the local part of the shielding member is automatically relaxed.

[0037] 3. In the present invention, the No. 2 motor drives the No. 2 connecting shaft to rotate forward, drives the No. 2 slider to move forward, drives the No. 1 swing member and the No. 2 swing member to rotate, increases the distance between the connecting seat and the connecting structure, and makes the connecting seat and the clamping moving mechanism move toward the patient side; the No. 2 motor drives the No. 2 connecting shaft to rotate in the opposite direction, drives the No. 2 slider to move in the opposite direction, drives the No. 1 swing member and the No. 2 swing member to rotate, reduces the distance between the connecting seat and the connecting structure, and makes the connecting seat and the clamping moving mechanism move toward the side away from the patient; in the initial stage of the No. 2 connecting shaft rotating forward, the connecting assembly drives the connecting member to slide, so that the distance between the connecting member and the connecting seat becomes the maximum, so that the distance between the No. 2 reel and the No. 1 reel is minimized, and the shielding member is partially clamped; in the initial stage of the No. 2 connecting shaft rotating in the opposite direction, the connecting assembly drives the connecting member to slide, so that the distance between the connecting member and the connecting seat becomes the minimum, so that the distance between the No. 2 reel and the No. 1 reel is maximized, and the shielding member is partially relaxed. In the initial stage of the movement of the connecting seat and the clamping moving mechanism toward the side away from the patient, the shielding member is automatically partially relaxed.

[0038] 4. In the present invention, during the initial forward rotation of the No. 2 connecting shaft, the drive unit drives the extrusion member to rotate forward, causing the connecting member to move away from the connecting seat. When the extrusion member rotates forward 90 degrees, it stops rotating, maximizing the distance between the connecting member and the connecting seat, minimizing the distance between the No. 2 reel and the No. 1 reel, and thereby partially clamping the shielding member. The drive unit then continues to rotate, establishing a rotational connection between the extrusion member and the drive unit, maintaining the No. 2 and No. 1 reels' grip on the shielding member.

[0039] At the beginning of the reverse rotation of the No. 2 connecting shaft, the driving unit drives the extrusion piece to rotate in the reverse direction. Under the suction of the No. 1 magnet and the No. 2 magnet, the connecting piece moves to the side close to the connecting seat. When the extrusion piece rotates 90 degrees in the reverse direction, the extrusion piece stops rotating, and the distance between the connecting piece and the connecting seat is minimized, so that the distance between the No. 2 reel and the No. 1 reel is maximized, and the shielding piece is partially relaxed. The driving unit continues to rotate, so that the extrusion piece forms a rotational connection with the driving unit, so that the No. 2 reel and the No. 1 reel remain partially relaxed on the shielding piece.

[0040] 5. In the present invention, the No. 1 protrusion increases the friction between the outer wall of the No. 1 reel and the surface of the shielding member, reduces the probability of slipping between the No. 1 reel and the shielding member, improves the reliability of the No. 1 reel driving the local movement of the shielding member, and improves the reliability of the clamping and moving mechanism.

DETAILED DESCRIPTION

[0059] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0060] like Figures 1-16 As shown, a shielding device for a non-radiotherapy area of ​​a tumor patient comprises a bed 1, a connecting seat 2, a telescopic mechanism 3, a clamping and moving mechanism 4, and a shielding member 5;

[0061] A sliding seat 11 is slidably connected to the bed body 1; a cover 12 is provided on the bed body 1; one end of the cover 12 is rotatably connected to the sliding seat 11;

[0062] The connecting seat 2 is symmetrically arranged in the housing 12; the connecting seat 2 and the housing 12 are connected via a telescopic mechanism 3; the telescopic mechanism 3 is used to drive the connecting seat 2 to move horizontally;

[0063] The shielding member 5 is made of a flexible radiation-proof material; a radiotherapy port 51 is provided in the middle of the shielding member 5;

[0064] The two connecting seats 2 are connected to the clamping and moving mechanisms 4; the two ends of the shielding member 5 are respectively connected to the two clamping and moving mechanisms 4; the clamping and moving mechanisms 4 are used to clamp a part of the shielding member 5; the clamping and moving mechanisms 4 are used to drive the part of the shielding member 5 to move;

[0065] The sliding seat 11 is connected to a fourth power mechanism 6 ; the fourth power mechanism 6 is used to drive the cover 12 to rotate; the bed body 1 is connected to a fifth power mechanism 7 ; the fifth power mechanism 7 is used to drive the sliding seat 11 to slide.

[0066] During operation, the medical staff uses the controller to operate the No. 4 power mechanism 6, which causes the cover 12 to rotate upward, so that the cover 12 rotates to the top of the sliding seat 11 and stops rotating. Then the patient lies flat in the middle of the bed 1. The medical staff uses the controller to operate the No. 4 power mechanism 6, which causes the cover 12 to rotate downward, so that the cover 12 rotates to the top of the patient and stops rotating. Then the medical staff uses the controller to operate the telescopic mechanism 3, so that the telescopic mechanism 3 extends and drives the connecting seat 2 and the clamping moving mechanism 4 to move to the side close to the patient. (In the initial stage of extension of the telescopic mechanism 3, the clamping mechanism 4 automatically clamps a portion of the shielding member 5), so that the two clamping mechanisms 4 move to both sides of the patient and stop moving. At this time, the clamping mechanism 4 maintains a clamped state on the portion of the shielding member 5. Then, the medical staff controls the clamping mechanism 4 to move through the controller. The clamping mechanism 4 drives the portion of the shielding member 5 located above the patient to move to both sides of the patient, so that the shielding member 5 is tightly attached to the patient's body, shielding the patient's body and reducing the chance of damage to the non-radiotherapy area during radiotherapy.

[0067] After the clamping movable mechanism 4 makes the shielding member 5 close to the patient's body, when the longitudinal position of the radiotherapy port 51 needs to be adjusted (the length direction of the bed body 1 is the longitudinal direction, and the width direction of the bed body 1 is the transverse direction), the medical staff shortens the telescopic mechanism 3 through the controller, and the telescopic mechanism 3 drives the connecting seat 2 and the clamping movable mechanism 4 to move a certain distance to the side away from the patient. During this process, the clamping movable mechanism 4 automatically loosens part of the shielding member 5, so that the shielding member 5 can move relative to the clamping movable mechanism 4, and then drives the sliding seat 11 to slide through the fifth power mechanism 7, driving the cover shell 12 to slide. The telescopic mechanism 3, the connecting seat 2 and the clamping mechanism 4 are driven to move, thereby driving the shielding member 5 to move longitudinally. Subsequently, the telescopic mechanism 3 is extended by the controller, so that the clamping mechanism 4 is moved to both sides of the patient's body. The shielding member 5 is then pressed against the patient's body by the clamping mechanism 4, thereby completing the adjustment of the longitudinal position of the radiotherapy port 51. When adjusting the longitudinal position of the radiotherapy port 51, the clamping mechanism 4 is kept at a certain distance from the patient's body, facilitating the longitudinal movement of the clamping mechanism 4. The clamping mechanism 4 loosens a portion of the shielding member 5, facilitating the longitudinal movement of the shielding member 5.

[0068] After the clamping movable mechanism 4 makes the shielding member 5 cling to the patient's body, when the lateral position of the radiotherapy port 51 needs to be adjusted, the controller causes one clamping movable mechanism 4 (the clamping movable mechanism 4 on the side where the radiotherapy port 51 needs to be moved away) to first move, driving the portion of the shielding member 5 located on the patient's side (the side where the radiotherapy port 51 needs to be moved away) to move between the two clamping movable mechanisms 4, thereby loosening the shielding member 5 on the patient's body. Subsequently, the other clamping movable mechanism 4 (the clamping movable mechanism 4 on the side where the radiotherapy port 51 needs to be moved closer to) is caused to move, driving the portion of the shielding member 5 located above the patient to move toward the patient's side (the side where the radiotherapy port 51 needs to be moved closer to), thereby adjusting the lateral position of the radiotherapy port 51.

[0069] After radiotherapy is completed, before rotating the cover 12 upward, the telescopic mechanism 3 is shortened to the shortest distance. At this time, the clamping movable mechanism 4 is away from the patient, and the shielding member 5 is automatically partially relaxed, making it convenient for the cover 12 to drive the telescopic mechanism 3, the clamping movable mechanism 4, the shielding member 5, etc. to rotate upward.

[0070] The clamping and moving mechanism 4 includes a first reel 41, a connecting member 42, a second reel 43, a connecting assembly 44 and a first power assembly 45;

[0071] The connecting seat 2 is rotatably connected to the first reel 41; the connecting seat 2 is slidably connected to the connecting member 42; the connecting member 42 is rotatably connected to the second reel 43; the end of the shielding member 5 is set between the first reel 41 and the second reel 43;

[0072] The connecting member 42 is connected to the telescopic mechanism 3 via a connecting assembly 44; the connecting assembly 44 is used to drive the connecting member 42 to move;

[0073] A first power assembly 45 is provided on the sliding seat 11 ; the first power assembly 45 is used to drive the first reel 41 to rotate.

[0074] When the telescopic mechanism 3 is extended and drives the connecting seat 2 and the clamping moving mechanism 4 to move toward the patient's side, the connecting assembly 44 drives the connecting member 42 to slide, increasing the distance between the connecting member 42 and the connecting seat 2, so that the distance between the connecting member 42 and the connecting seat 2 becomes the maximum, and the distance between the No. 2 reel 43 and the No. 1 reel 41 is minimized. At this time, the No. 2 reel 43 and the No. 1 reel 41 are respectively squeezed on both sides of the local part of the shielding member 5, clamping the local part of the shielding member 5, which is convenient for later driving the local movement of the shielding member 5; when the telescopic mechanism 3 is shortened and drives the connecting seat 2 and the clamping moving mechanism 4 to move away from the patient's side, the connecting assembly 44 drives the connecting member 42 to slide, reducing the distance between the connecting member 42 and the connecting seat 2, so that the distance between the connecting member 42 and the connecting seat 2 becomes the minimum, so that the distance between the No. 2 reel 43 and the No. 1 reel 41 is maximized, and the local part of the shielding member 5 is relaxed. In the early stage of the clamping moving mechanism 4 away from the patient's body, the local part of the shielding member 5 is automatically relaxed.

[0075] When the clamping moving mechanism 4 needs to be clamped and moved, the controller activates the first power assembly 45, which drives the first reel 41 to rotate. The outer wall of the first reel 41 generates friction on the shielding member 5, driving a part of the shielding member 5 to move.

[0076] When the longitudinal position of the radiotherapy port 51 needs to be adjusted, the telescopic mechanism 3 is shortened through the controller, driving the connecting seat 2 and the clamping moving mechanism 4 to move a certain distance to the side away from the patient. At this time, there is a certain distance between the No. 1 reel 41 and the patient's body, which facilitates the longitudinal movement of the No. 1 reel 41.

[0077] The housing 12 has connecting structures 121 symmetrically disposed at both ends. The connecting base 2 and the connecting structure 121 are connected via a telescopic mechanism 3. The telescopic mechanism 3 includes a first slider 31, a second slider 32, a first swinging member 33, a second swinging member 34, a hinge shaft 35, a second connecting shaft 36, and a second motor 37.

[0078] The connecting structure 121 is slidably connected to the first slider 31; the connecting base 2 is slidably connected to the second slider 32; one end of the first swinging member 33 is rotatably connected to the first slider 31; the other end of the first swinging member 33 is rotatably connected to the connecting base 2; one end of the second swinging member 34 is rotatably connected to the connecting structure 121; the other end of the second swinging member 34 is rotatably connected to the second slider 32; the first swinging member 33 and the second swinging member 34 are hingedly connected via a hinge shaft 35;

[0079] The connecting seat 2 is rotatably connected to the second connecting shaft 36; the second connecting shaft 36 is provided with a threaded structure 361; the second slider 32 is threadedly connected to the threaded structure 361; the connecting assembly 44 is connected to the second connecting shaft 36;

[0080] The connecting base 2 is fixedly connected to a No. 2 motor 37 ; the No. 2 motor 37 is used to drive the No. 2 connecting shaft 36 to rotate.

[0081] When the telescopic mechanism 3 needs to be extended to drive the connecting seat 2 and the clamping moving mechanism 4 to move toward the side closer to the patient, the controller is used to operate the No. 2 motor 37, the No. 2 motor 37 drives the No. 2 connecting shaft 36 to rotate forward, drives the threaded structure 361 to rotate forward, drives the No. 2 slider 32 to move forward, drives the No. 1 swinging member 33 and the No. 2 swinging member 34 to rotate, increases the distance between the connecting seat 2 and the connecting structure 121, and moves the connecting seat 2 and the clamping moving mechanism 4 toward the side closer to the patient; when the telescopic mechanism 3 needs to be extended to drive the connecting seat 2 and the clamping moving mechanism 4 to move toward the side away from the patient, the controller is used to operate the No. 2 motor 37, the No. 2 motor 37 drives the No. 2 connecting shaft 36 to rotate in the opposite direction, drives the threaded structure 361 to rotate in the opposite direction, drives the No. 2 slider 32 to move in the opposite direction, drives the No. 1 swinging member 33 and the No. 2 swinging member 34 to rotate, reduces the distance between the connecting seat 2 and the connecting structure 121, and moves the connecting seat 2 and the clamping moving mechanism 4 toward the side away from the patient;

[0082] At the initial stage of the forward rotation of the No. 2 connecting shaft 36, the connecting assembly 44 drives the connecting member 42 to slide, increasing the distance between the connecting member 42 and the connecting seat 2, so that the distance between the connecting member 42 and the connecting seat 2 becomes the maximum, and the distance between the No. 2 reel 43 and the No. 1 reel 41 is minimized. At this time, the No. 2 reel 43 and the No. 1 reel 41 are respectively squeezed on both sides of the local part of the shielding member 5, clamping the local part of the shielding member 5, which is convenient for later driving the local part of the shielding member 5 to move; at the initial stage of the reverse rotation of the No. 2 connecting shaft 36, the connecting assembly 44 drives the connecting member 42 to slide, reducing the distance between the connecting member 42 and the connecting seat 2, so that the distance between the connecting member 42 and the connecting seat 2 becomes the minimum, and the distance between the No. 2 reel 43 and the No. 1 reel 41 is maximized, and the local part of the shielding member 5 is relaxed. At the initial stage of the movement of the connecting seat 2 and the clamping moving mechanism 4 to the side away from the patient, the local part of the shielding member 5 is automatically relaxed.

[0087] The connecting seat 2 is fixedly connected to the first magnet 446 ; the connecting piece 42 is fixedly connected to the second magnet 447 .

[0088] At the initial stage of the positive rotation of the No. 2 connecting shaft 36, the driving part 362 is driven to rotate forward. When a driving groove 3621 rotates to a position facing the driving member 443, the elastic force of the elastic member 444 causes the sliding column 442 to move toward the side of the driving groove 3621, causing the driving member 443 to move toward the side of the driving groove 3621, so that the driving member 443 contacts the driving groove 3621. At this time, under the action of the driving member 443, the extruding member 441 and the driving part 362 rotate synchronously, and the driving part 362 drives the extruding member 441 to rotate forward. In the process of the driving part 362 driving the extruding member 441 to rotate forward, the side wall of the No. 2 arc portion 4412 contacts the connecting member 42, generating a thrust on the connecting member 42, resisting the suction of the No. 1 magnet 446 and the No. 2 magnet 447, causing the connecting member 42 to move to the side away from the connecting seat 2. When the pressing piece 441 rotates forward 90 degrees, the extruding piece 441 stops rotating. At this time, the second arc portion 4412 is located on the left side of the driving part 362, and the distance between the connecting piece 42 and the connecting seat 2 is the largest, so that the distance between the second reel 43 and the first reel 41 is the smallest, and the shielding piece 5 is partially clamped. The driving part 362 continues to rotate, so that the driving piece 443 disengages from the driving groove 3621, so that the extruding piece 441 and the driving part 362 form a rotational connection, so that the second reel 43 and the first reel 41 keep clamping the shielding piece 5; when the extruding piece 441 starts to rotate forward, the arc inner wall of one end of the limiting groove 4415 abuts against the side wall of the limiting column 445. When the extruding piece 441 rotates forward 90 degrees, the arc inner wall of the other end of the limiting groove 4415 abuts against the side wall of the limiting column 445, so that the extruding piece 441 stops rotating.

[0089] At the beginning of the reverse rotation of the No. 2 connecting shaft 36, the driving part 362 is driven to rotate in the reverse direction. When a driving groove 3621 rotates to a position facing the driving member 443, the elastic force of the elastic member 444 causes the sliding column 442 to move toward the driving groove 3621, causing the driving member 443 to move toward the driving groove 3621, causing the driving member 443 to abut against the driving groove 3621. At this time, under the action of the driving member 443, the extruding member 441 and the driving part 362 rotate synchronously, and the driving part 362 drives the extruding member 441 to rotate in the reverse direction. During the process of the driving part 362 driving the extruding member 441 to rotate in the reverse direction, the side wall of the No. 2 arc portion 4412 is detached from the connecting member 42. Under the suction force of the No. 1 magnet 446 and the No. 2 magnet 447, the connecting member 42 moves to the side close to the connecting seat 2. When the extrusion member 441 rotates 90 degrees in the opposite direction, the extrusion member 441 stops rotating. At this time, the No. 2 arc portion 4412 is located above the driving portion 362. The distance between the connecting member 42 and the connecting seat 2 is minimized, so that the distance between the No. 2 reel 43 and the No. 1 reel 41 is maximized, and the shielding member 5 is partially relaxed. The driving portion 362 continues to rotate, so that the driving member 443 disengages from the driving groove 3621, so that the extrusion member 441 forms a rotational connection with the driving portion 362, so that the No. 2 reel 43 and the No. 1 reel 41 remain partially relaxed on the shielding member 5.

[0090] Number one protrusions are evenly spaced on the outer wall of the number one reel 41 .

[0091] The No. 1 protrusion increases the friction between the outer wall of the No. 1 reel 41 and the surface of the shielding member 5, reduces the probability of slipping between the No. 1 reel 41 and the shielding member 5, improves the reliability of the No. 1 reel 41 driving the local movement of the shielding member 5, and improves the reliability of the clamping movement mechanism 4.

[0095] The limiting post 445 is rotatably connected to the connecting seat 2 , and the limiting post 445 can roll on the inner wall of the limiting groove 4415 to reduce the friction between the limiting post 445 and the inner wall of the limiting groove 4415 .

[0096] Limiting structures 52 are provided at both ends of the shielding member 5 .

[0097] By providing the limiting structure 52 , the end of the shielding member 5 is prevented from being separated from between the first reel 41 and the second reel 43 during the rotation of the cover 12 toward the top of the sliding seat 11 , thereby improving the reliability of the shielding device.

After the cover shell 12 rotates to the top of the sliding seat 11 and stops rotating, the cover shell 12 will not rotate downward, preventing the cover shell 12 from rotating downward and colliding with the user; the worm gear 62 and the worm 63 have a self-locking effect. After the cover shell 12 rotates to the top of the patient and stops rotating, the cover shell 12 will not rotate.
