Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, and in particular to a seated rotational treatment terminal for precise tumor localization. Background Technology

[0002] Currently, in particle therapy, patients are primarily positioned lying down, relying on a treatment bed for positioning. However, for certain specific areas (such as the head and neck, chest and lungs), sitting therapy offers unique advantages. For example, it can utilize gravity to reduce tissue and organ displacement, shorten the radiation path to lower the radiation dose to normal tissues, and facilitate respiratory management for patients.

[0003] Existing particle-based seated therapy positioning devices mostly adopt standardized frame structures, which are only suitable for general body shape characteristics and are difficult to fit the individual physiological curves of patients. In addition, existing devices cannot quickly switch the adaptation modules for different lesion sites. For example, the fixation areas required for head tumor treatment are different from those for lung tumor treatment, and traditional devices are difficult to adjust flexibly, leaving room for improvement. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The following is for reference. Figures 1-10 This invention describes a seated rotational therapy terminal 100 for precise tumor localization, which can perform multi-posture treatment on patients, thereby conforming to the patient's personalized physiological curve, improving the treatment effect, and can quickly switch between adaptation modules, making it convenient and flexible to use.

[0048] like Figures 1-10 As shown, a seated rotational therapy terminal 100 for precise tumor localization according to an embodiment of the present invention includes: a support platform 1, a seat module 2, a first backrest module 3, and a second backrest module 4.

[0049] The seat module 2 is movably mounted on the support platform 1, and the seat module 2 has a sitting position and a standing position relative to the support platform 1. The first backrest module 3 is adapted to be detachably connected to the seat module 2 when the seat module 2 is in the sitting position. The first backrest module 3 includes a head fixation member 34 for fixing the patient's head. The second backrest module 4 is adapted to be detachably connected to the seat module 2 when the seat module 2 is in the standing position. The second backrest module 4 includes an arm support assembly and an affected area fixation member. The arm support assembly is used to support the patient's arm, and the affected area fixation member is used to fix the patient's affected area.

[0050] The seated rotational therapy terminal 100 is used for particle radiotherapy. The seated rotational therapy terminal 100 can fix the patient during particle irradiation, ensuring precise treatment of the affected area, guaranteeing treatment reliability, and improving treatment efficacy.

[0051] Specifically, the seated rotation therapy terminal 100 is equipped with a support platform 1. The structure of the seated rotation therapy terminal 100 can be installed on the support platform 1, and rollers or other structures can be installed below the support platform 1 to facilitate the movement of the seated rotation therapy terminal 100. The support platform 1 can be set as a circular platform or a rectangular platform, etc. In actual treatment, the support platform 1 can be moved forward and backward, left and right, and up and down, and can also be adjusted by swaying left and right or tilting forward and backward, etc. The setting method is flexible. The seated rotation therapy terminal 100 is also equipped with a seat module 2. The seat module 2 is installed above the support platform 1, and the seat module 2 has a seated position and a standing position relative to the support platform 1. That is, the height of the seat module 2 relative to the support platform 1 is adjustable. When the patient needs to sit on the seat module 2 for treatment, the height of the seat module 2 can be lowered to the seated position. When the patient needs to sit in a semi-standing position or stand upright for treatment, the height of the seat module 2 can be raised to the standing position. In this way, it can be used for treatment in a variety of postures, thus improving the applicability.

[0052] Furthermore, the seated rotation therapy terminal 100 is also provided with a first backrest module 3, which is detachably installed on the seat module 2. The first backrest module 3 is suitable for use when the seat module 2 is in a seated position. That is, when the seat module 2 is in a seated position, the first backrest module 3 can be installed on the seat module 2. When the seat module 2 is not in a seated position, the first backrest module 3 can be detached and replaced with other backrest structures to adapt to different postures of the patient.

[0053] Furthermore, the seated rotation therapy terminal 100 is also equipped with a second backrest module 4, which is detachably installed on the seat module 2. The second backrest module 4 is suitable for use when the seat module 2 is in an upright position. That is, when the seat module 2 is in an upright position, the second backrest module 4 can be installed on the seat module 2. When the seat module 2 is not in an upright position, the second backrest module 4 can be disassembled and replaced with other backrest structures to adapt to different postures of the patient.

[0054] The first backrest module 3 includes a headrest 34, which can be used to fix the patient's head. That is, when the seat module 2 is in a sitting position, the first backrest module 3 can be installed on the seat module 2. In this way, the headrest 34 can be installed on the seat module 2, so that when the patient sits on the seat module 2, the headrest 34 can fix the patient's head to ensure the stability of the patient's head position, and thus the patient's head and neck can be treated.

[0055] The second backrest module 4 includes an arm support assembly and a fixation component for the affected area. The arm support assembly can be used to support the patient's arm, and the fixation component for the affected area is used to fix the patient's affected area. That is, when the seat module 2 is in an upright position, the second backrest module 4 can be installed on the seat module 2. In this way, the arm support assembly and the fixation component for the affected area can be installed on the seat module 2, so that when the patient is semi-standing or fully standing in front of the seat module 2, the arm support assembly can support and fix the patient's arm, and the fixation component for the affected area can fix the patient's affected area to ensure the stability of the position of the patient's arm and affected area, and to prevent the patient's arm from obstructing the patient's chest, lungs or lower abdomen, thereby enabling treatment of the patient's chest, lungs or lower abdomen.

[0056] Thus, the seat module 2 has different states, and different states correspond to different backrest modules, which enables the sitting rotation therapy terminal 100 to treat patients in multiple postures to fit the patient's personalized physiological curve, improve the treatment effect, and quickly switch the adaptation module according to different postures, making it convenient, flexible, and more effective with a wider range of applications.

[0057] According to an embodiment of the present invention, a seated rotational therapy terminal 100 for precise tumor localization has a first backrest module 3 that can be detachably installed on the seat module 2 when the seat module 2 is in a seated position, and a second backrest module 4 that can be detachably installed on the seat module 2 when the seat module 2 is in an upright position. This allows the seated rotational therapy terminal 100 to perform multi-posture treatment on the patient to conform to the patient's personalized physiological curve, improve the treatment effect, and quickly switch the adaptation module according to different postures. It is convenient, flexible, and has better effects and a wider range of applications.

[0058] In some embodiments, the first backrest module 3 further includes a lifting back panel, which is detachably connected to the seat module 2 via a first connecting part 31. The lifting back panel extends vertically and its length is adjustable. The head fixing member 34 is installed on the upper end of the lifting back panel.

[0059] Specifically, the first backrest module 3 is detachably installed on the seat module 2, and the first backrest module 3 is also provided with a lifting back panel, which extends vertically, such as... Figure 3 As shown, the lower end of the lifting back panel is provided with a first connecting part 31, which can be connected to the seat module 2 through the first connecting part 31, so that the first back panel module 3 is detachable relative to the seat module 2, so that the seat module 2 can be replaced with different seat modules 2 in different states. The head fixing member 34 is installed on the upper end of the lifting back panel, so that when the patient sits on the seat module 2, his back can lean against the lifting back panel, and his head can be fixed through the head fixing member 34 to fix the patient's posture, ensure the accuracy of treatment, and improve the treatment effect.

[0060] Furthermore, the lifting backrest is designed to be vertically adjustable, allowing the height of the headrest 34 mounted on its upper end to be adjustable. Specifically, when the lifting backrest is extended, the headrest 34 can be raised; when the lifting backrest is shortened, the headrest 34 can be lowered. This allows for upward adjustment of the headrest 34 for taller patients and downward adjustment for shorter patients, thus accommodating patients of different heights and conforming to their individual physiological curves. In actual use, such as... Figure 3 As shown, a plug-in part 311 can be provided at the lower end of the first connecting part 31, and a plug-in mating part can be provided on the seat module 2. The first connecting part 31 can be plugged into the seat module 2 to achieve relative detachability, simple structure and convenient installation.

[0061] In some embodiments, the lifting back panel includes a primary back panel 32 and a secondary back panel 33, which are movably connected in a vertical direction. The lower end of the primary back panel 32 is connected to the first connecting part 31, and the upper end of the secondary back panel 33 is connected to the head fixing member 34. The primary back panel 32 has forward-extending handrails 321 on both sides.

[0062] Specifically, the headrest 34 can be detachably installed on the seat module 2 via the lifting back panel, and as... Figure 3As shown, the lifting backrest is provided with a primary backrest 32 and a secondary backrest 33. The primary backrest 32 and the secondary backrest 33 are connected vertically and are relatively movable. The lower end of the primary backrest 32 is connected to a first connecting part 31, which can be detachably connected to the seat module 2. The upper end of the primary backrest 32 is movably connected to the lower end of the secondary backrest 33, and the upper end of the secondary backrest 33 is connected to the head fixing member 34. Thus, the overall length of the lifting backrest can be adjusted by adjusting the insertion depth of the primary backrest 32 and the secondary backrest 33.

[0063] In actual settings, such as Figure 3 As shown, an upward-opening insertion slot can be provided in the primary back plate 32, and the lower end of the secondary back plate 33 can be inserted into the insertion slot of the primary back plate 32. This allows for adjustment of the upward extension length of the secondary back plate 33 relative to the primary back plate 32. The secondary back plate 33 and the primary back plate 32 can be set for manual or electric adjustment. A locking structure can be provided in the primary back plate 32. The locking structure can be constructed as a bolt or a locking block. When the secondary back plate 33 is manually adjusted to a suitable length, the bolt can be tightened to press against the secondary back plate 33, or the locking block can be pressed against the secondary back plate 33 with an interference fit, thereby fixing the secondary back plate 33. A lead screw can also be provided in the primary back plate 32. When the lead screw is driven to rotate, it can drive the secondary back plate 33 to rise and fall. The setting method is flexible.

[0064] In addition, such as Figure 1 As shown, armrests 321 are also provided on both sides of the primary back panel 32. The armrests 321 extend forward on both sides of the primary back panel 32, so that the patient's arms can be placed on the armrests 321 when sitting on the seat module 2, thereby improving the comfort of use.

[0065] In some embodiments, the second backrest module 4 further includes a mounting back panel 42, which is connected to the seat module 2 via a second connecting portion 41. The mounting back panel 42 extends vertically, and an arm support assembly is movably mounted on the upper part of the mounting back panel 42.

[0066] Specifically, the second backrest module 4 is detachably installed on the seat module 2, and the second backrest module 4 is also provided with a mounting back panel 42, which extends vertically, such as... Figure 7 As shown, the lower end of the mounting back panel 42 is provided with a second connecting part 41, which can be connected to the seat module 2 through the second connecting part 41, so that the second backrest module 4 is detachable relative to the seat module 2, so that the seat module 2 can be replaced with different seat modules 2 in different states. The arm support assembly is installed on the upper end of the mounting back panel 42, so that when the patient sits on the seat module 2, the back can be leaned against the mounting back panel 42, and the arm can be fixed through the arm support assembly to fix the patient's posture, ensure the accuracy of treatment, and improve the treatment effect.

[0067] Furthermore, the mounting backplate 42 is configured to have an adjustable length in the vertical direction, making the height of the arm support assembly mounted on the upper end of the mounting backplate 42 adjustable. That is, when the length of the mounting backplate 42 is extended, the height of the arm support assembly can be raised, and when the length of the mounting backplate 42 is shortened, the height of the arm support assembly can be lowered. This allows the arm support assembly to be adjusted upwards when the patient is taller and downwards when the patient is shorter, thus adapting to patients of different heights and conforming to the patient's personalized physiological curve. In actual installation, a plug-in part can be provided at the lower end of the second connecting part 41, and a plug-in mating part can be provided on the seat module 2. The second connecting part 41 can be plugged into the seat module 2 to achieve relative detachability, simple structure, and convenient installation.

[0068] In addition, such as Figure 6 As shown, the mounting back panel 42 is provided with a first back panel 423 and a second back panel 424. The first back panel 423 and the second back panel 424 are vertically connected and can move relative to each other. The lower end of the first back panel 423 is connected to a second connecting part 41, and the second connecting part 41 can be detachably connected to the seat module 2. The upper end of the first back panel 423 is movably connected to the lower end of the second back panel 424. The upper end of the second back panel 424 is connected to the arm support assembly. In this way, the overall length of the lifting back panel can be adjusted by adjusting the insertion depth of the first back panel 423 and the second back panel 424.

[0069] In actual settings, such as Figures 6-7 As shown, a downward-opening insertion slot can be provided in the second back plate 424, and the upper end of the first back plate 423 can be inserted into the insertion slot of the second back plate 424, thereby adjusting the length of the first back plate 423 extending relative to the second back plate 424. The second back plate 424 and the first back plate 423 can be set to be manually or electrically adjustable. An adjustment switch 422 can be provided in the second back plate 424. When the second back plate 424 is manually adjusted to a suitable length, the adjustment switch 422 can be tightened to press against the first back plate 423, thereby fixing the second back plate 424. A lead screw can also be provided in the first back plate 423. When the lead screw is driven to rotate, the second back plate 424 can be raised and lowered. The setting method is flexible.

[0070] In actual installation, the fixation device for the affected area can be constructed as a positioning membrane. A positioning membrane connection hole can be provided in the mounting back plate 42. The positioning membrane can be installed on the mounting back plate 42 through the positioning membrane connection hole. The positioning membrane and the mounting back plate 42 can define the area to accommodate the affected area. The shape of the positioning membrane can be changed according to the shape of the affected area to adapt to the affected area in different locations, improve the adaptability of use, and ensure the reliability of the position restriction of the affected area.

[0071] In some embodiments, the arm support assembly includes two elbow supports 43 and two hand grips 44, the two hand grips 44 being located above the two elbow supports 43, wherein the two hand grips 44 are movably mounted on both sides of the mounting back plate 42, the two elbow supports 43 are rotatably mounted on both sides of the mounting back plate 42, and the spacing between the two elbow supports 43 is adjustable.

[0072] Specifically, the arm support assembly is mounted on the upper end of the mounting backplate 42, and as... Figure 2 As shown, the arm support assembly includes an elbow support 43 and a hand grip 44. The hand grip 44 is located above the elbow support 43. When the seat module 2 is in the upright position, the second backrest module 4 can be installed on the seat module 2. The patient can stand or be semi-standing in front of the seat module 2 and place their elbow on the elbow support 43 or hold the hand grip 44, thereby avoiding the hands from covering the chest, abdomen or lower abdomen, and ensuring the reliability of treatment.

[0073] Furthermore, both the grip bar 44 and the elbow support 43 are provided in pairs, with the two grip bars 44 movably mounted on both sides of the mounting back plate 42, such as... Figure 2 As shown, a third slider 441 can be provided at one end of the grip bar 44 near the mounting back plate 42, and a first slide rail 421 extending vertically is provided on both sides of the mounting back plate 42. This allows the grip bar 44 to slide vertically with the first slide rail 421 of the mounting back plate 42 via the third slider 441, thereby adjusting the height of the grip bar 44 to accommodate patients of different heights. The grip bar 44 also has multiple insertion holes 443 along its length and a grip part 442, which can be selectively inserted into the multiple insertion holes 443 to accommodate patients of different arm lengths. In actual installation, the grip bar 44 can also be made rotatable to fit the patient's personalized physiological curve.

[0074] Additionally, two elbow supports 43 are rotatably mounted on both sides of the mounting backplate 42, and the distance between the two elbow supports 43 is adjustable. Figure 2 As shown, a first slider 431 can be provided at one end of the elbow support 43 near the mounting back plate 42, and a first slide rail 421 extending vertically is provided on both sides of the mounting back plate 42. This allows the elbow support 43 to slide vertically with the first slide rail 421 of the mounting back plate 42 through the first slider 431, thereby adjusting the height of the elbow support 43 to accommodate patients of different heights.

[0075] And such as Figure 2As shown, the first slider 431 is provided with a second slide rail 432 extending away from the mounting back plate 42, and the second slide rail 432 is provided with a second slider 433 that slides with it. The second slider 433 is also connected to a rotating rod 434 extending forward. The support arm 435 is used to support the patient's elbow. The support arm 435 is rotatably connected to the rotating engagement part 436, and the rotating engagement part 436 rotates with the rotating rod 434, thereby making the distance between the two elbow support members 43 adjustable. The setting angle and position of the support arm 435 in the front-back direction can also be adjusted, which can improve the fit to the patient's personalized physiological curve.

[0076] In some embodiments, the arm support assembly includes two elbow supports 43 and two hand grips 44, with the two hand grips positioned above the two elbow supports 43. The two hand grips 44 are mounted on the front side of the mounting back plate 42 and extend forward. The two elbow supports 43 are movably mounted on the mounting back plate 42 via an adjusting slider 437, and the spacing between the two elbow supports 43 is adjustable.

[0077] Specifically, the arm support assembly is mounted on the upper end of the mounting backplate 42, and as... Figure 8 As shown, the arm support assembly includes an elbow support 43 and a hand grip 44. The hand grip 44 is located above the elbow support 43. When the seat module 2 is in the upright position, the second backrest module 4 can be installed on the seat module 2. The patient can stand or be semi-standing in front of the seat module 2 and place their elbow on the elbow support 43 or hold the hand grip 44, thereby avoiding the hands from covering the chest, abdomen or lower abdomen, and ensuring the reliability of treatment.

[0078] Furthermore, there are two grip bars 44 and two elbow supports 43. The two grip bars 44 are installed on the front side of the mounting back plate 42 and extend forward. The mounting back plate 42 is provided with a plurality of mating holes 425 spaced apart in the vertical direction. The grip bars 44 can be selectively inserted into the mating holes 425, thereby adjusting the height of the grip bars 44 in the vertical direction to accommodate patients of different heights. The grip bars 44 are provided with a plurality of insertion holes 443 along the length direction. The grip bars 44 are also provided with a hand grip 442, which can be selectively inserted into the plurality of insertion holes 443 to accommodate patients of different arm lengths.

[0079] In addition, such as Figures 8-9As shown, two elbow supports 43 are movably mounted on the mounting back plate 42 via adjusting sliders 437. The mounting back plate 42 has first slide rails 421 extending vertically on both sides. The adjusting sliders 437 and the first slide rails 421 of the mounting back plate 42 slide vertically together. Both elbow supports 43 are mounted on the adjusting sliders 437, so that the height of the two elbow supports 43 can be adjusted simultaneously via the adjusting sliders 437, ensuring consistent adjustment.

[0080] In some embodiments, the elbow support 43 is provided with a support arm 435 and a connecting rod 438. The support arm 435 is mounted on the adjusting slider 437 via the connecting rod 438. The connecting rod 438 includes a horizontal connecting section 4381 and a vertical connecting section 4382. One end of the horizontal connecting section 4381 is connected to the adjusting slider 437, and the other end is connected to the upper end of the vertical connecting section 4382, so as to jointly define a disease area avoidance area 439. The disease area avoidance area 439 is used to avoid the patient's treatment area.

[0081] Specifically, such as Figures 8-9 As shown, the elbow support 43 is provided with a support arm 435 and a connecting rod 438. The support arm 435 is used to support the patient's elbow. The support arm 435 is rotatably connected to the rotating engagement part 436, and the rotating engagement part 436 is rotatably engaged with the rotating rod 434. The rotating engagement part 436 can also slide with the rotating rod 434, so that the setting angle and position of the support arm 435 in the front-back direction can be adjusted, which can improve the fit to the patient's personalized physiological curve.

[0082] In addition, the connecting rod 438 is provided with a horizontal connecting section 4381 and a vertical connecting section 4382. The horizontal connecting section 4381 extends in the horizontal direction, and the vertical connecting section 4382 extends in the vertical direction. One end of the horizontal connecting section 4381 is connected to the adjusting slider 437, and the connection length between the horizontal connecting section 4381 and the adjusting slider 437 can be adjusted by means of a pin or other structure, thereby adjusting the distance between the two elbow support members 43.

[0083] The other end of the horizontal connecting section 4381 is connected to the upper end of the vertical connecting section 4382, so that the connecting rod 438 is constructed as a downwardly bent rod structure. The rotating rod 434 is connected to the lower end of the vertical connecting section 4382, so that the horizontal connecting section 4381 and the vertical connecting section 4382 jointly define the affected area avoidance area 439. The affected area avoidance area 439 is used to avoid the patient's treatment area to ensure the reliability of the patient's treatment.

[0084] In actual setup, it can also be done as follows: Figure 10As shown, the hand grip 44 is constructed as a semi-ring structure and is inserted into the mating hole 425 of the mounting back plate 42, so that the hand grip 44 and the mounting back plate 42 can jointly define the hand grip area. The user can extend his hand into the hand grip area and hold the hand grip 44, thereby improving the flexibility of the treatment posture.

[0085] In some embodiments, a seated rotational therapy terminal 100 for precise tumor localization further includes an abdominal fixation member 5, which is adapted to be detachably connected to the seat module 2 when the seat module 2 is in a seated position, and the abdominal fixation member 5 is used to limit the patient's abdomen.

[0086] Specifically, such as Figure 1 and Figures 4-5 As shown, the seated rotation therapy terminal 100 also includes an abdominal fixation member 5. When the seat module 2 is in a seated position, the patient can sit on the seat module 2. After the patient is seated, the abdominal fixation member 5 can be installed on the seat module 2 so that the abdominal fixation member 5 can limit the patient's abdomen and ensure the patient's stability during treatment. The abdominal fixation member 5 is detachable from the seat module 2. That is, when the seat module 2 is in an upright position, the abdominal fixation member 5 can be removed for easy inspection.

[0087] When the patient needs to sit in the seat module 2, the abdominal fixation piece 5 can be removed. After the patient is seated, the abdominal fixation piece 5 can be installed in the seat module 2 to limit the patient's position. After the treatment is completed, the abdominal fixation piece 5 can be removed, allowing the patient to leave the seat module 2, thus improving the convenience of treatment.

[0088] In some embodiments, the seat module 2 is provided with a plug-in fixing block, and the end of the abdominal fixing member 5 is adapted to be plugged into the plug-in fixing block. The plug-in fixing block has a locked state and an unlocked state. The plug-in fixing block is adapted to move relative to the seat module 2 in the front-back direction when it is unlocked, and is adapted to move rearward or lock relative to the seat module 2 when it is locked.

[0089] Specifically, the seat module 2 is provided with a plug-in fixing block, and the left and right sides of the seat module 2 are both formed with adjustment grooves 211 extending in the front-back direction. The two ends of the abdominal fixing member 5 can respectively extend into the two adjustment grooves 211 to plug into and cooperate with the plug-in fixing block in the seat module 2. In actual installation, a plug-in switch 51 can be provided on the abdominal fixing member 5, and plug-in buckles can be provided on both ends of the abdominal fixing member 5. The plug-in buckles can plug into and cooperate with the plug-in fixing block, and when the plug-in switch 51 is pressed, the plug-in buckles can be separated from the plug-in fixing block, thereby allowing the abdominal fixing member 5 to be separated from the seat module 2. The structure is simple and the operation is convenient.

[0090] Furthermore, the insertion and fixing block is also provided with a locked state and an unlocked state. When the insertion and fixing block is in the unlocked state, the insertion and fixing block can move in the front-back direction relative to the seat module 2, that is, the abdominal fixation piece 5 can move in the front-back direction relative to the seat module 2, thereby adjusting the tightness of the patient's restraint. When the insertion and fixing block is in the locked state, the insertion and fixing block can only move backward relative to the seat module 2, thereby pressing the patient's abdomen. The insertion and fixing block can also be set to lock relative to the seat module 2 in the locked state, that is, the insertion and fixing block is stationary relative to the seat module 2 in the locked state, ensuring that the patient will not move during treatment and improving the accuracy of treatment.

[0091] In actual installation, a locking switch 212 can be installed in the seat module 2, and the locking switch 212 is connected to a pawl. The seat module 2 is also equipped with a ratchet that meshes with the plug-in fixing block. When the locking switch 212 is closed, the pawl and the ratchet are separated, and the plug-in fixing block can move in the front-back direction. When the locking switch 212 is open, the pawl and the ratchet are in contact, so that the ratchet can only rotate in one direction, and thus the plug-in fixing block can only move backward. Alternatively, the plug-in fixing block can be constructed as a pivot pin, so that when the plug-in fixing block is plugged into the seat module 2, it can be locked relative to the seat module 2. The structure is simple and the operation is convenient.

[0092] In some embodiments, the head fixation member 34 is configured as a fixed mask, the fixed mask defining a head receiving space 341 for receiving the patient's head, and the fixed mask forming a facial avoidance area 342 communicating with the head receiving space 341.

[0093] Specifically, the headrest 34 is installed at the upper end of the lifting backrest and is detachable from the seat module 2 along with the lifting backrest. Figure 1 and 3 As shown, the head fixation component 34 can be configured as a fixed mask. The fixed mask protrudes forward from the upper end of the lifting back plate and forms a head receiving space 341. The lower end of the fixed mask is open, allowing the patient to extend their head into the head receiving space 341 from the lower end of the fixed mask. This allows the fixed mask to limit the patient's head in any direction along the horizontal plane, ensuring the accuracy of head treatment. The front of the fixed mask forms a facial avoidance area 342 that communicates with the head receiving space 341. The facial avoidance area 342 can avoid the patient's face, allowing the patient's face to be detected by optical surface or other monitoring equipment, enabling doctors to observe the patient's condition and ensuring the reliability of treatment.

[0094] In actual setup, the head fixing component 34 can also be configured as a positioning membrane. The upper end of the lifting back plate is provided with a positioning membrane connection hole. The positioning membrane can be installed on the upper end of the lifting back plate through the positioning membrane connection hole. The positioning membrane and the upper end of the lifting back plate can define the head placement area. The shape of the positioning membrane can be changed according to the patient's head shape to adapt to patients with different head shapes and improve the adaptability.

[0095] In some embodiments, the seat module 2 includes a seat body 21 and a seat cushion 22. A first backrest module 3 or a second backrest module 4 is detachably connected to the seat body 21. The seat body 21 forms a forward-opening clearance space 213, and the seat cushion 22 is rotatably mounted in the clearance space 213.

[0096] Specifically, such as Figure 4 As shown, the seat module 2 is provided with a seat body 21 and a seat cushion 22. The seat body 21 can be raised and lowered relative to the support platform 1, so that the seat module 2 can have a sitting position and a standing position. The first backrest module 3 or the second backrest module 4 is detachably connected to the seat body 21. When the seat module 2 is in the sitting position, the first backrest module 3 can be detachably connected to the seat body 21. When the seat module 2 is in the standing position, the second backrest module 4 can be detachably connected to the seat body 21, improving the flexibility of use.

[0097] Furthermore, a clearance space 213 is formed at the front of the seat body 21. The clearance space 213 is open to the front, and the seat cushion 22 is rotatably installed in the clearance space 213. That is, when the seat module 2 is in a sitting position, the seat cushion 22 can be adjusted to be parallel to the horizontal plane or have a small angle to support the patient. When the seat module 2 is in an upright position, the seat cushion 22 can be rotated downward at a certain angle so that the patient part can be located in the clearance space 213, so as to avoid the seat cushion 22 obstructing the patient and improve the range of use.

[0098] In actual settings, such as Figure 4 As shown, a telescopic rod 221 can be connected to the seat cushion 22 below the seat body 21 away from the seat body 21. The other end of the telescopic rod 221 is connected to the seat body 21. The rotation angle of the seat cushion 22 can be adjusted by adjusting the length of the telescopic rod 221. The structure is simple and the operation is convenient.

[0099] In some embodiments, a seated rotational therapy terminal 100 for precise tumor localization further includes a lifting module 6. The seat module 2 is mounted on the support platform 1 via the lifting module 6. The lifting module 6 is used to adjust the height of the seat module 2 so that the seat module 2 has a seated position and a standing position.

[0100] Specifically, such as Figures 4-7As shown, the seated rotation therapy terminal 100 is also equipped with a lifting module 6. The lifting module 6 can be installed on the support platform 1, and the seat module 2 can be connected to the lifting module 6, so that the seat module 2 can be installed above the support platform 1 through the lifting module 6. The lifting module 6 extends vertically and its height in the vertical direction can be adjusted, thereby adjusting the height of the seat module 2 in the vertical direction so that the seat module 2 can have a seated position and a standing position. In actual installation, a lifting slide can be set on the rear side of the seat module 2, and a lifting slider can be set on the support platform 1. The lifting slider can extend into the lifting slide, and the lifting slide can slide vertically relative to the lifting slider under manual or electric action, thereby adjusting the height of the seat module 2. The structure is simple and the operation is convenient.

[0101] In some embodiments, a seated rotational therapy terminal 100 for precise tumor localization further includes a foot pedal module 7, which is movably mounted on the support platform 1 in the front-back direction and located in front of the seat module 2. The foot pedal module 7 is used to limit the patient's legs.

[0102] Specifically, the seated rotational therapy terminal 100 is also equipped with a foot pedal module 7, such as... Figure 1 and Figure 6 As shown, the foot pedal module 7 is located in front of the seat module 2. The foot pedal module 7 is provided with a foot limiting block 71 and a leg limiting plate 72. The foot limiting block 71 and the leg limiting plate 72 are spaced apart in the front-back direction, and the leg limiting plate 72 is located in front of the foot limiting block 71. The patient can put the back of his foot against the foot limiting block 71 and the front of his lower leg against the leg limiting plate 72, thereby limiting the patient's leg and ensuring the accuracy of the treatment.

[0103] In addition, the foot pedal module 7 is movably mounted on the support platform 1 in the front-to-back direction, so that the foot pedal module 7 can be used for patients with different leg lengths, thus improving the applicability. In actual setup, the foot pedal module 7 can be driven by a screw or other structure, thus improving the flexibility of setup.

[0104] In some embodiments, the upright position includes a semi-upright position and a standing position. The height of the seat module 2 increases sequentially in the sitting position, semi-upright position and standing position. The foot pedal module 7 is adapted to be installed on the support platform 1 when the seat module 2 is in the semi-upright position.

[0105] Specifically, the standing position also includes a semi-standing position and a standing position. In the semi-standing position, the patient's legs are slightly bent and their buttocks are partially resting on the seat cushion 22. In the standing position, the patient stands upright with their buttocks separated from the seat cushion 22. The height of the seat module 2 increases sequentially in the sitting, semi-standing, and standing positions, with the lowest height in the sitting position and the highest height in the standing position, to accommodate different patient postures during treatment. Figure 6As shown, the foot pedal module 7 is suitable for installation on the support platform 1 when the seat module 2 is in a semi-upright position. That is, the foot pedal module 7 can limit the patient's legs when the patient's legs are slightly bent, so as to ensure the accuracy of treatment.

[0106] In some embodiments, the seat module 2 is adapted to be in a seated position when the seated rotational therapy terminal 100 treats the patient's head and neck area. That is, when the seated rotational therapy terminal 100 is used to treat the patient's head and neck area, the seat module 2 can be adjusted to a seated position. The seat module 2 is also adapted to be in a seated or semi-standing position when the seated rotational therapy terminal 100 is used to treat the patient's chest and abdomen area. That is, when the seated rotational therapy terminal 100 is used to treat the patient's chest and abdomen area, the seat module 2 can be adjusted to a seated or semi-standing position. Furthermore, the seat module 2 is adapted to be in a standing position when the seated rotational therapy terminal 100 is used to treat the patient's lower abdomen area. That is, when the seated rotational therapy terminal 100 is used to treat the patient's lower abdomen area, the seat module 2 can be adjusted to a standing position. Thus, the seated rotational therapy terminal 100 can be used to treat the patient in multiple postures to conform to the patient's personalized physiological curves and improve the treatment effect.

[0107] In actual treatment, the treatment area can be divided into three major areas according to the patient's treatment position and the characteristics of the seated rotational treatment terminal 100: head and neck area, chest and abdomen area and lower abdomen area, and three types of postures are adopted respectively: seated position, semi-standing position and standing position.

[0108] When treating the head and neck area, such as Figure 5 As shown, the patient adopts a sitting posture, selects the first backrest module 3, adjusts the angle of the first backrest module 3, and adjusts the angle between the seat cushion 22 and the horizontal to -5°~+5°. The patient sits on the seat cushion 22, fixes the thermoplastic film to the corresponding area of ​​the first backrest module 3 and the treatment area, places the arm on the armrest 321, and presses the abdomen with the abdominal fixation piece 5.

[0109] When treating the chest and abdominal region, such as Figure 6 As shown, the patient adopts a semi-standing posture, selects the second backrest module 4, adjusts the angle of the second backrest module 4, and adjusts the seat module 2 to a certain height using the lifting module 6. The angle between the seat cushion 22 and the horizontal is adjusted to -5° to +85°. The patient sits on the seat cushion 22 with their arms placed on the arm support component. The thermoplastic film is fixed to the corresponding area of ​​the second backrest module 4 and the treatment area. The thermoplastic film can also be fixed to a vacuum bag, and the vacuum bag is fixed to the corresponding area of ​​the second backrest module 4 and the treatment area. The legs and feet are fixed using the foot pedal module 7.

[0110] When treating the chest and abdominal areas, patients can also adopt a sitting posture, which can be adjusted according to the actual treatment needs.

[0111] When treating the area below the abdomen, such as Figure 7 As shown, the patient adopts a standing posture, selects the second backrest module 4, and adjusts the seat module 2 to a certain height using the lifting module 6. The angle between the seat cushion 22 and the horizontal is adjusted to +85°~+95°. The patient's back is pressed against the second backrest module 4, and the arms are placed on the arm support component. The thermoplastic film is fixed to the corresponding area of ​​the second backrest module 4 and the treatment area. The thermoplastic film can also be fixed to a vacuum bag, and the vacuum bag is fixed to the corresponding area of ​​the second backrest module 4 and the treatment area. The legs and feet are fixed using the foot pedal module 7.
