Description

Technical Field

[0001] This invention belongs to the field of radiotherapy tool technology, and specifically relates to an auxiliary frame structure and method of using for placing a body membrane during radiotherapy in paralyzed patients. Background Technology

[0002] For complex and irregular lesions in the chest and abdomen, or tumors that move significantly with respiration, patients typically require a custom-made body membrane to anchor their bodies during radiotherapy. The body membrane is a mold made of a low-temperature thermoplastic polymer sheet before radiotherapy. Its function is to fix the patient's chest and abdomen in place, ensuring a close fit to the patient's skin and preventing displacement during radiotherapy. This restricts the patient's position, improves the accuracy of radiotherapy, and prevents radiation damage to healthy tissues and organs. Tumor radiotherapy involves CT scans to obtain images tailored to each individual and location, which are then transmitted to the target area system. The planned target area is delineated, and the doctor evaluates the radiotherapy plan and verifies the tumor's location. Conventional targeted radiotherapy is usually administered multiple times over several days. The patient's position must be consistent during each treatment session. Each treatment session typically lasts 5-10 minutes, but with patient cooperation, the time spent on positioning and membrane clamping can be 1-2 times longer than the actual irradiation time. However, when radiotherapy patients are unable to cooperate actively, the time required to adjust their position and fix their position with body membranes is usually longer.

[0003] During radiotherapy, the patient typically lies supine on the bed with their head resting on a headrest, facing upwards. Three positioning markers or lines are marked on the patient's body. Positioning is determined by the patient actively moving back and forth and side to side to align the markers with the positioning lines, ensuring proper body positioning. A pre-made body membrane is then used to secure the body to the radiotherapy bed. The body membrane is fastened to the radiotherapy bed using snaps or locks, ensuring the body is firmly confined to the designated position.

[0004] The prior art discloses a precise radiotherapy positioning and placement device for body tumors, with the publication number CN216571246U. The entire device is placed on the radiotherapy treatment bed, and the patient lies flat on the shaping pad with both hands raised to hold the adjustment rod. The patient not only needs to actively adjust their body posture to find the correct position, but each patient also needs to use the entire device containing the shaping pad. One set of the entire device is customized for each patient. The overall structure is complex and expensive, and it is not interchangeable between patients. Each patient needs to spend time and effort repeatedly disassembling and assembling the corresponding entire device containing the shaping pad.

[0005] Typically, when a patient lies flat on a treatment bed without their chest membrane fixed, technicians and doctors need to adjust the patient's position. Adjusting the position is laborious, especially for patients with limited mobility; moving on the bed after lying down is even more difficult. However, when paralyzed patients undergoing radiotherapy for tumors are placed on a flat radiotherapy bed, laser lines are used to locate three points on the patient's body. Paralyzed patients cannot move independently on the radiotherapy bed and cannot actively cooperate with the physician in adjusting their position. Medical staff must forcefully pull the patient's body; too little force and they cannot move at all, too much and too little, resulting in extremely poor precision in adjustment. The process of locating the three points is slow, time-consuming, and laborious. Each positioning process is physically demanding for medical staff, leading to prolonged use of the radiotherapy equipment and indirectly reducing the efficiency of the expensive equipment.

[0006] For patients undergoing thoracic and abdominal radiotherapy who are unable to actively cooperate with medical staff in positioning and alignment on the radiotherapy bed or have poor self-cooperation and adjustment, there are urgent technical problems that need to be solved, such as poor precision in positioning adjustments before each placement of the body membrane during multiple radiotherapy sessions and inconvenience in positioning. Summary of the Invention

[0007] This invention provides an auxiliary frame structure and method of use for placing a body membrane during radiotherapy in paralyzed patients, in order to solve the aforementioned technical problems.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an auxiliary frame structure for placing a body membrane during radiotherapy in paralyzed patients, characterized in that it comprises:

[0009] A truss frame is used to connect with the treatment bed. The bottom of the truss frame is provided with an opening platform, and a locking handle is provided on the outside of the opening platform. The truss frame is fitted onto the treatment bed through the opening platform and locked by the locking handle. Double long slide bars are provided on both sides inside the truss frame.

[0010] The bottom push plate support is located at the center of the bed end of the truss frame. The bottom push plate support also includes a rocker arm, a telescopic column, a clamping block, two short slide bars, and a sliding foot support.

[0011] Side pushers are distributed on both sides of the truss frame, and the side pushers are placed on the double long slide bars in a sliding fit connection manner;

[0012] A side pry bar is rotatably connected to the end of the telescopic rod of the side pusher. A folding rod is provided on the upper part of the side pry bar, and a folding pry plate is provided on the lower part of the side pry bar. The folding rod and the folding pry plate are arranged in an L-shape to lift the body of the paralyzed patient to adjust the height of the body.

[0013] The bottom push plate, the side push plate, and the side pry bar allow for planar and vertical movement adjustment of the paralyzed patient's body position.

[0014] Preferably, the rear end of the telescopic column is bolted to the truss frame, the front protruding end of the telescopic column is bolted to the clamp block, and the rocker arm is inserted into the bottom of the telescopic column in a keyed connection manner, and the telescopic column is extended or shortened by rotating the rocker arm.

[0015] Preferably, the middle part of the double short slide bar is bolted to the clamp block, and the sliding footrest is slidably connected to the double short slide bar.

[0016] Preferably, there are two sliding footrests, which are evenly distributed on both sides of the double short slide bars. A locking screw is provided between the sliding footrest and the double short slide bars. The sliding footrest is provided with a foot groove, which is L-shaped.

[0017] Preferably, both the telescopic column and the double short slide bars are provided with scale lines.

[0018] Preferably, a limiting pillow is provided on the opposite side of the bottom push plate support. The limiting pillow is L-shaped and is placed at the center of the treatment bed. A hand post is provided on the truss frame on the top side of the limiting pillow, and a wrist strap is provided at the base of the hand post.

[0019] Preferably, the number of side pushers is four, and the four side pushers are evenly distributed on the two double-long slide bars.

[0020] Preferably, the side pusher includes a slide block, a turntable column, a telescopic rod, and a universal joint. The slide block is slidably connected to the double long slide bar. The center of the slide block is connected to the base of the telescopic rod. The turntable column is inserted into the telescopic rod in a keyed connection for threaded transmission. The extended end of the telescopic rod is connected to the side skid through the universal joint.

[0021] Preferably, the universal joint includes a ball head, a hemispherical cap, and a hemispherical seat. The diameter of the ball head is greater than or equal to twice the diameter of the extended end of the telescopic rod. The ball head is threaded to the extended end of the telescopic rod. The hemispherical cap is threaded to the hemispherical seat. The ball head is placed inside the hemispherical seat and the hemispherical cap for a clearance-type sliding fit. The hemispherical seat is bolted to the side skid.

[0022] Preferably, the upper part of the side skid paddle is provided with a rotating rod groove, a slot, and a plate groove in sequence. The bottom of the folding rod is provided with a pivot pin. The folding rod is clearance-fitted with the rotating rod groove and the slot. The folding rod is rotatably connected to the upper part of the side skid paddle in the rotating rod groove through the pivot pin. When the folding rod is inserted into the slot, the folding rod and the upper part of the side skid paddle cannot rotate through the pivot pin. The folding skid plate is rotatably connected to the lower end of the side skid paddle. The folding skid plate is placed in the plate groove in a clearance-fit manner.

[0023] The beneficial effects of this invention are as follows: This invention uses a truss frame to secure the outside of the treatment bed. After a paralyzed patient who cannot move independently lies on the treatment bed, the patient's body can be moved and adjusted in a planar position by using the bottom push plate support, side push plate support, and side pry paddle on the truss frame. The adjustment accuracy of the body movement is high, and the process of positioning and aligning is time-saving and labor-saving. In addition, the side pry paddle can also lift one side of the body through the lever principle, ensuring that after the body is moved horizontally on the treatment bed, the back muscles can be returned to a natural state by lifting the body, which can improve the comfort of lying flat. Furthermore, the patient's head and feet can be limited by the limiting pillow and the foot groove of the bottom push plate support, respectively. The patient's hips can be restrained by the side push plate support and the side pry paddle on both sides. Combined with the body membrane for limiting the body, this can effectively ensure the accuracy of the patient's body position and improve the maintenance of the body's positioning position. The invention has a simple structure. The side pusher with the side pry bar can slide within the truss frame via two long slide bars. The two foot grooves can slide along two short slide bars, ensuring that patients of different heights can use it. It has good versatility and excellent practicality. Attached Figure Description

[0043] The present invention will now be further described in conjunction with the accompanying drawings:

[0044] Combination Figures 1 to 14 As shown, the present invention discloses an auxiliary frame structure and method for placing a body membrane for radiotherapy in paralyzed patients, including a truss frame 1, double long slide bars 2, bottom push plate support 3, side push support 4, side pry bar 5, limiting pillow 6, and hand column 7.

[0045] The specific structure and principle of the above-mentioned components of the auxiliary frame according to the present invention will be described in detail below.

[0046] As an example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, patients with limited mobility or paralysis can lie on the treatment bed 81 of the radiotherapy machine 8. A truss frame 1 can be provided around the treatment bed 81. Viewed from above, the truss frame 1 can form a rectangular circle around the edge of the treatment bed 81. An opening platform 11 can be provided at the bottom of the truss frame 1. The opening platform 11 is clearance-fitted to the edge of the treatment bed 81. The truss frame 1 is secured to the edge of the bed by the opening platform 11. A locking handle 12 is provided on the outside of the opening platform 11. The truss frame 1 is fitted onto the treatment bed 81 by the opening platform 11 and locked by the locking handle 12. The locking handle 12 is a set screw type locking, so that the truss frame 1 is firmly placed on the treatment bed 81. The locking handle 12 is a structure in which a wrench drives a threaded set screw to rotate. The wrench and the set screw are connected by a shaft rotation, which makes it convenient to use the locking handle 12 to lock or loosen the truss frame 1 and the treatment bed 81.

[0047] The truss frame 1 can be a rectangular ring formed by connecting four truss structures end to end. The cross-section of each truss structure can be a square truss structure. The square truss structure has strong stability and load-bearing capacity, which enhances the overall stability of the truss frame 1. Not only is the truss frame 1 less prone to deformation, but the truss structure also effectively reduces the overall weight of the truss frame 1. Furthermore, the truss frame 1 can be made of carbon fiber tubing material in one piece, which not only has minimal impact on photon rays, but also improves structural strength and is lighter than solid materials. The weight of the truss frame 1 can be between 2 and 5 kilograms, which can be easily handled by an adult male or female. The truss frame 1 can be quickly placed on the treatment bed 81 and quickly locked by the locking handle 12.

[0048] Reference Figures 2 to 6 As shown, double-long slide bars 2 are provided on both sides of the interior of the truss frame 1. The double-long slide bars 2 can be columnar or bar-shaped structures, and the two bars can be bolted together on one side of the truss frame 1 in parallel. Side push supports 4 can be provided on the double-long slide bars 2. The side push supports 4 are placed on the double-long slide bars 2 in a sliding fit connection manner. Each double-long slide bar 2 can be provided with two side push supports 4, and four side push supports 4 can be provided on both sides of the interior of the truss frame 1.

[0049] As an example, such as Figure 11 , Figure 12 , Figure 13 , Figure 14As shown, the side pusher 4 includes a slide 41, a turntable column 42, a telescopic rod 43, and a universal joint 44. The slide 41 is slidably connected to the double long slide bar 2. The slide 41 can be made into a sheet-like structure supported by ribs. The telescopic rod 43 can be a threaded telescopic rod structure. The base of the telescopic rod 43 is bolted to the center of the slide 41. The turntable column 42 is inserted into the telescopic rod 43 in a keyed manner. The turntable column 42 can drive the threaded stud in the telescopic rod 43 to rotate, so that the telescopic rod 43 can extend or shorten. The extended end of the telescopic rod 43 is threadedly connected to one end of the universal joint 44. The other end of the universal joint 44 is provided with a side pry bar 5. The extended end of the telescopic rod 43 is movably connected to the side pry bar 5 through the universal joint 44.

[0050] Example 1

[0051] As an example, such as Figures 1 to 7 As shown, a paralyzed radiotherapy patient with limited mobility lies on the treatment bed 81. The patient can adjust their position on the bed using the four side supports 4 evenly distributed on both sides of their body. Specifically, refer to... Figure 7 , Figure 11 , Figure 12 and Figure 13As shown, when it is necessary to move the patient to one side, the turntable column 42 can be inserted into the telescopic rod 43. Manually rotating the turntable column 42 extends the telescopic rod 43. The side pry bar 5 at the extended end of the telescopic rod 43 is flat, allowing it to contact the patient's body and increasing the contact area for improved comfort when moving the patient. The universal joint 44 between the side pry bar 5 and the telescopic rod 43 can change the angle of the side pry bar 5, ensuring better contact with the patient's body. Continuing to manually rotate the turntable column 42 extends the telescopic rod 43, allowing the patient to be moved. In use, one rotation of the turntable column 42 extends or shortens the telescopic rod 43 by 2 to 8 mm, ensuring quick and easy control of the telescopic rod 43's extension and retraction while reducing the effort required to rotate the turntable column 42. Furthermore, it allows for precise control of the patient's translational movement on the bed. The turntable column 42 may have a ring-shaped scale marking the rotation required to advance the telescopic rod 43 by 1 mm. The laser positioning lamp 82 of the radiotherapy machine 8 can emit positioning light projected onto the patient's body; when adjusting the patient's position on the bed by rotating the turntable column 42, the projected positioning line can be used as a reference. The side pry bar 5 can preferentially contact the patient's shoulder or hip, pushing the patient in this area to quickly change the body's position without causing harm. When used by patients of different heights, the side pusher 4 can be manually and quickly moved and repositioned by the sliding seat 41 and the double long slide bar 2. This allows the side levers 5 on the side pusher 4 to be quickly aligned with the shoulders or hips of patients of different heights, facilitating the movement of the patient in both left and right directions on the bed. When the body is tilted, one side lever 5 can push one shoulder, and the other can push the symmetrical hips, quickly correcting the body position. This method is suitable for changing the angle of the body's tilt on the bed and is extremely effective in adjusting the position when lying on the side. The side pusher 4 and the side levers 5 of this device have excellent precision in adjusting the body position, greatly reducing the workload of medical staff when dealing with patients who do not cooperate with the positioning, and speeding up the adjustment speed. It can be quickly adjusted and used for patients of different heights, increasing the efficiency of patient positioning and greatly saving effort.

[0052] Example 2

[0053] As an example, such as Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, the universal joint 44 includes a ball head 441, a hemispherical cover 442, and a hemispherical seat 443. The ball head 441 is spherical and is threadedly connected to the extended end of the telescopic rod 43. The hemispherical cover 442 is threadedly connected to the hemispherical seat 443. The hemispherical cover 442 and the hemispherical seat 443 form a spherical cavity. The ball head 441 is placed inside the hemispherical cover 442 and the hemispherical seat 443 for clearance fit, and the ball head 441 is placed inside the hemispherical seat 443 and the hemispherical cover 442 for articulated sliding fit. The diameter of the ball head 441 is greater than or equal to twice or more the diameter of the extended end of the telescopic rod 43, which ensures that the angle of rotation of the hemispherical seat 443 and the hemispherical cover 442 on the ball head 441 is increased, and the range of motion of the ball head 441 at the joint is increased. The hemispherical seat 443 is bolted or threaded to the side pry bar 5, and the side pry bar 5 can rotate to change its angle based on the ball head 441 as the fulcrum.

[0054] See attached document Figure 11 , Figure 12 , Figure 13 As shown, the side pry bar 5 also includes a folding rod 51, a folding pry plate 52, a rotating rod groove 53, a slot 54, and a plate groove 55. The folding rod 51 is located at the upper part of the side pry bar 5, the folding pry plate 52 is located at the lower part of the side pry bar 5, and the rotating rod groove 53, slot 54, and plate groove 55 are sequentially arranged at the upper part of the side pry bar 5. The folding rod 51 can be telescopic, with a sleeve and rod slidingly engaged. When the sleeve of the folding rod 51 is pulled out, the overall length of the folding rod 51 increases, ensuring an increase in the lever arm when using a lever-type prying action, allowing the doctor to perform prying operations with minimal force. A pivot pin 511 is located at the bottom of the folding rod 51. The pivot pin 511 is a cylindrical shaft and can be threaded to the folding rod 51 or integrally formed. The folding rod 51, the rotating rod groove 53, and the slot 54 are all clearance-fitted. The folding rod 51 passes through the rotating rod groove 53. The pivot pin 511 is rotatably connected to the upper part of the side pry bar 5. At this time, the folding rod 51 can be upright or laid flat around the pivot pin 511, ensuring that the folding rod 51 does not need to be upright and occupy space when not in use. When the folding rod 51 is upright and the folding rod 51 and the pivot pin 511 are inserted into the slot 54 together, the folding rod 51 and the pivot pin 511 are inserted into the slot 54 in a clearance fit. When the folding rod 51 is inserted into the slot 54, the folding rod 51 and the upper part of the side pry bar 5 cannot rotate through the pivot pin 511.

[0055] See attached document Figure 14As shown, after the folding rod 51 is inserted into the slot 54, manually moving the folding rod 51 can cause the side pry bar 5 to rotate around the ball head 441 of the universal joint 44. The folding pry plate 52 is placed in the plate groove 55 with a clearance fit; when the folding pry plate 52 is placed in the plate groove 55, the outer surface of the folding pry plate 52 can form a transitional plane with the surface of the side pry bar 5, ensuring that there are no protruding hard objects that would cause discomfort or injury when the side pry bar 5 comes into contact with a person's body; the folding pry plate 52 is rotatably connected to the lower end of the side pry bar 5, and after the folding pry plate 52 is rotated open in the plate groove 55, it can be placed in an L-shape with the side pry bar 5. In this embodiment, the folding lever 52 can be placed under the body. Manually moving the folding rod 51 backward can lift the folding lever 52 upward around the ball head 441, realizing the lever principle of lifting heavy objects through a fulcrum. This ensures that doctors or technicians can lift the patient with minimal force, allowing the patient to quickly find the positioning point on the body using the positioning light emitted by the laser positioning light 82 on the treatment bed 81. This enables rapid height adjustment of the patient's body. Lifting one side of the patient can return the accumulated skin and flesh on the bed to a natural position. This not only facilitates positioning before chemotherapy but also greatly improves the patient's comfort while lying down. It saves time and effort and can be used by people of different weights or heights. Even petite women or those with less strength can use this device to quickly find and adjust patients who cannot cooperate independently to the correct position.

[0056] Example 3

[0057] As an example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a bottom push plate support 3 can be provided at the center of the truss frame 1 at the foot of the treatment bed 81. The bottom push plate support 3 includes a rocker arm 31, a telescopic column 32, a clamping block 33, double short slide bars 34, and a sliding footrest 35. The telescopic column 32 and the telescopic rod 43 have the same structure, both being telescopic rods that extend or shorten by rotating and driving threads. The rocker arm 31 can be inserted into the telescopic column 32 with a keyed pin to drive the telescopic column 32 to extend or shorten. The structure of extending or shortening the telescopic column 32 by rotating the rocker arm 31 can be the same as the telescopic structure of the rocker arm 42 and the telescopic rod 43. The rear end of the telescopic column 32 is bolted to the truss frame 1, and the front protruding end of the telescopic column 32 is bolted to the clamping block 33. The middle part of the double short slide bars 34 is bolted to the clamping block 33. The sliding footrest 35 and the double short slide bars 34 are connected by a clearance fit sliding fit. A limiting pillow 6 is provided on the opposite side of the bottom push plate support 3. The limiting pillow 6 is L-shaped and is placed at the center of the treatment bed 81 and is clamped to the treatment bed 81. A hand post 7 is provided on the truss frame 1 on the top side of the limiting pillow 6. The hand post 7 is threaded to the truss frame 1. A wrist strap 71 is provided at the base of the hand post 7. The wrist strap 71 can be a hook-and-loop strap.

[0058] Reference Figure 9 and Figure 10 As shown, Figure 9 and Figure 10 This is an enlarged schematic diagram of the bottom support plate 3. The number of adjustable footrests 35 on the double short slide bars 34 can be two, evenly distributed on both sides. Both the telescopic column 32 and the double short slide bars 34 can be provided with scale lines 36. A locking screw 351 is provided between the adjustable footrest 35 and the double short slide bars 34. After the adjustable footrest 35 on the double short slide bars 34 is adjusted to its position, it can be locked by the locking screw 351 to prevent the adjustable footrest 35 from moving on the double short slide bars 34. Each of the two adjustable footrests 35 is provided with a foot groove 352, which is L-shaped. The patient can place their foot into the foot groove 352 of the adjustable footrest 355. A hook and loop fastener, similar to a wristband 71, can be provided on the foot groove 352 to quickly tighten the foot. The telescopic column 32 can be extended or shortened manually using the crank lever 31, allowing for adjustment of the patient's position in both forward and backward directions.

[0059] See attached document Figure 8 As shown, attached Figure 8This diagram illustrates the locked body position for radiotherapy after the pleura 91 is fixed. The laser positioning light 82 of the radiotherapy machine 8 can project a positioning reference line or a positioning baseline. Three intersecting reference lines will be marked on the body of a paralyzed patient who cannot move independently. The correct position is achieved when the positioning point line on the patient's body completely coincides with the positioning point line of the laser positioning light 82. The paralyzed patient who cannot move independently can move or rotate their body in two directions on the treatment bed 81 using the side pushers 4 and the side pryers 5 on both sides. The side pryers 5 can also raise and lower the body. Furthermore, the bottom push plate 3 can push the patient's feet so that the patient's head is completely placed inside the L-shaped limit pillow 6, enabling rapid adjustment of the patient's position on the treatment bed 81. After the patient's position is correctly adjusted, the patient raises their arm and binds their wrist with the wristband 71, or the patient grasps the hand post 7 themselves, so that the positioning point 91 on the body coincides with the positioning point 91 emitted by the laser positioning light 82. The pleura 9 is then fastened, so that the positioning point 91 on the pleura 9 coincides with the positioning point 91 on the body and the positioning point 91 of the laser positioning light 82. The side pryers 5 on both sides can be placed on the hips and tightened by the side pushers 4 to restrain the body position. The feet can be restrained by the bottom pusher 3 and the limiting pillow 6 on the opposite side, so that the patient's position is locked in all four directions (front, back, left, and right), ensuring that the patient is well restrained and locked in place on the treatment bed 81. With the pleura 9 matching the patient's body, the patient is stably positioned on the treatment bed 81, ensuring that the radiation from the radiotherapy machine 8 can be effectively and accurately delivered to the lesion for chemotherapy. This device has a simple structure and can be made from materials suitable for use in radiotherapy rooms, such as carbon fiber, or materials with low density, such as polyethylene and polypropylene. Radiotherapy rays can easily penetrate these materials without being blocked. Furthermore, the lightweight nature of the carbon fiber construction allows for easy installation and removal from the treatment bed by a single person. The patient's position can be quickly adjusted by a single person, and the rotating disc-type drive telescopic rod allows for precise adjustment of the patient's position. The fine-tuning of the patient's position is extremely precise, controllable within a 0.5mm accuracy range. Moreover, it can be used by patients of different heights, offering excellent versatility and saving time and effort in the positioning process. In addition, the patient's hips, head, and feet can be locked in place, and combined with the body membrane's restraint, this effectively ensures the accuracy of the patient's body position and improves the consistency of the body's positioning. This facilitates a higher degree of accuracy in aligning the center point of the radiotherapy rays with the center point of the tumor. High-precision body positioning greatly improves the accuracy of target area localization, a crucial prerequisite for precise radiotherapy.

[0060] The manually driven telescopic rod 43 and telescopic column 32, including the rocker arm 31 and the turntable column 42, can also be driven by a hand-held decelerated electric drill. However, the metal materials and electric transmission structure are not suitable for use in radiotherapy rooms. Therefore, this invention does not prioritize electric drive under the premise of ensuring the safe use of radiotherapy machines.
