Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a radiotherapy auxiliary fixing bracket with an anti-displacement function. Background Art

[0002] Radiotherapy is one of the important means of cancer treatment. It is often used to accurately kill malignant tumor cells while minimizing damage to surrounding normal tissues. During radiotherapy, patients need to maintain a specific posture to ensure that the radiation can accurately irradiate the target area. However, patients may move slightly due to discomfort, breathing, muscle fatigue and other factors, causing the irradiation area to shift, thereby affecting the treatment effect and even causing unnecessary damage to healthy tissues.

[0003] In the prior art, a Chinese patent document with publication number CN107961448A proposes a support and fixation device for radiotherapy, including a fixed positioning plate, a first connecting frame and a second connecting frame are respectively provided on the front and rear sides of the fixed positioning plate, and the first connecting frame and the second connecting frame are fixedly connected to the fixed positioning plate by drawing, and auxiliary support plates are provided on the left and right sides of the fixed positioning plate. Although this technology can finely adjust and fix the fixing device through the fine-tuning bracket, it effectively avoids the occurrence of the fixed bracket breaking due to small deviation fixation and long time, and effectively ensures the safety of patients during radiotherapy, but this technology is consistent with the traditional method in that: the traditional Conventional technology has obvious defects in fixing the patient's arms, especially when performing radiotherapy on different areas such as the chest, chest sides and head. Since the traditional bracket is fixed, the bracket lacks sufficient flexibility, making it impossible to quickly and accurately switch the support position for radiotherapy in different positions, which makes it difficult to maintain the optimal treatment angle and arm position during treatment. At the same time, since the traditional bracket simply places the arm on the bracket when fixing the arm, it is impossible to keep the arm in a stable position. This design can easily cause the patient's arm to shift during treatment, resulting in errors in radiotherapy in other positions, which in turn affects the treatment effect. Summary of the invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a bracket assembly, a clamping assembly and a driving assembly, the position of the bracket assembly is adjusted by the driving assembly, so that the bracket assembly can fix the patient's arm from different positions, thereby facilitating radiotherapy of the patient at different positions. At the same time, the adjustment device of the bracket assembly can also ensure that the arm position does not accidentally shift through a locking mechanism after the bracket is adjusted, thereby avoiding radiotherapy errors caused by slight displacement of the arm. In particular, the adjustment of the clamping assembly and the linkage design of the bracket can maintain the stability of the arm when the patient's position is fine-tuned, thereby ensuring the accuracy of the treatment process.

[0016] By setting up the bracket assembly, the patient's arms can be flexibly fixed, and the arm support position can be quickly adjusted according to the position of different radiotherapy areas (such as the chest, chest side and head), thereby facilitating radiotherapy of patients in different positions. At the same time, through the adjustability of the bracket assembly, the bracket can be accurately positioned according to treatment needs to ensure stable support throughout the treatment process, avoiding the problems of inflexible fixation and difficult adjustment in traditional technologies. This flexibility allows therapists to quickly respond to different treatment angles and avoid treatment errors caused by improper arm position. When performing head radiotherapy on the patient, the bracket assembly can be rotated to the top of the bed board. At this time, the arms will be fixed on both sides of the patient's chest, thereby facilitating head radiotherapy for the patient. At the same time, when treating the patient's chest and chest side, the bracket assembly can be rotated to both sides of the patient's head. At this time, the arms will be fixed on both sides of the patient's head, thereby facilitating radiotherapy of the patient's chest and chest side.

[0017] By setting up a clamping component, it can automatically adjust according to the size of the patient's arm to ensure optimal comfort and support when the forearm is fixed, avoiding the problem that the traditional bracket can only simply support the patient's arm, thereby causing an unstable fixed position. The clamping component uses the weight of the patient's arm to automatically clamp, which can fit the shape of the patient's arm tightly, and is fixed with adhesive straps and Velcro, thereby avoiding the possibility of arm displacement. At the same time, by adjusting the fixing pressure and position, the clamping component enhances the stability of the arm, ensuring that the patient's arm is always in the correct position throughout the treatment process, thereby avoiding the problem of arm displacement during radiotherapy.

[0018] By setting up a drive component, a quick adjustment mechanism is provided, which can adjust the position of the bracket assembly in one step, avoiding the tedious process of changing the bed due to adjusting the arm position in traditional technology. The therapist only needs to operate the drive component to quickly adjust the arm position, saving time and improving operating efficiency. At the same time, the flexibility of the drive component not only enables the bracket assembly to quickly switch the support position, but also ensures that the bracket will not be displaced during the entire treatment process, thereby eliminating treatment errors caused by arm displacement.

[0024] like Figures 1 to 10As shown, an embodiment of the present invention provides a radiotherapy auxiliary fixing bracket with an anti-displacement function, comprising a base 1, a seat plate 2 is fixedly connected to the top of the base 1, a bed plate 3 is installed on the top of the seat plate 2, two straps 47 are symmetrically fixedly connected to the top of one end of the bed plate 3, and a bracket assembly is arranged on the top of the other end of the bed plate 3, the bracket assembly is used to fix the patient's arm to ensure that when radiotherapy is performed on different areas such as the chest, chest side, head, etc., the bracket can quickly switch and maintain a stable supporting position, a clamping assembly is arranged on the top of the bracket assembly, the clamping assembly is used to automatically adjust and fix according to the size of the patient's arm, to ensure that the forearm can obtain optimal comfort and support when fixed, a driving assembly is arranged on the bottom of the bed plate 3, the driving assembly is used to adjust the position of the bracket assembly in one step, to ensure that the treatment personnel can quickly adjust the radiotherapy position, and reduce the operation time during the treatment process, the bracket assembly, the clamping assembly and the driving assembly are used in conjunction with each other to ensure that the arm position is always stable during the treatment process, thereby avoiding radiotherapy errors caused by arm displacement; By setting up the bracket assembly, clamping assembly and driving assembly, and adjusting the position of the bracket assembly through the driving assembly, the bracket assembly can be prompted to fix the patient's arm from different positions, thereby facilitating radiotherapy of different positions of the patient. At the same time, the adjustment device of the bracket assembly can also ensure that the arm position does not accidentally shift through a locking mechanism after the bracket is adjusted, thereby avoiding radiotherapy errors caused by slight displacement of the arm. In particular, the adjustment of the clamping assembly and the linkage design of the bracket can still maintain the stability of the arm when the patient's position is fine-tuned, thereby ensuring the accuracy of the treatment process.

[0025] like Figures 1 to 3 as well as Figures 6 to 8 As shown, the bracket assembly includes a support plate 4 rotatably connected to the two sides of the top of the bed board 3 and symmetrically arranged, the two ends of the top of the support plate 4 are respectively fixedly connected with the first support plate 5 and the second support plate 7, the first adjustment rod 6 is fixedly connected between the first support plate 5 and the second support plate 7, the first adjustment rod 6 is slidably connected to the outside of the first adjustment rod 6, the second connecting rod 9 is fixedly connected to one side of the second support plate 7, the end of the second connecting rod 9 away from the second support plate 7 is rotatably connected to the first connecting rod 8 through an axis, the end of the first connecting rod 8 away from the second connecting rod 9 is fixedly connected to the third support plate 10, one side of the third support plate 10 is fixedly connected to the second adjusting rod 12, the second adjusting rod 12 is slidably connected to two movable cylinders 17, one side of the movable cylinder 17 outside the first adjusting rod 6 is fixedly connected to the large arm plate 15, and one side of the two movable cylinders 17 outside the second adjusting rod 12 are respectively fixedly connected to the second small arm plate 14 and the first small arm plate 13, and the positions of the first small arm plate 13 and the second small arm plate 14 correspond to the positions of the human body's forearms; By means of the support assembly, the patient's arm can be flexibly fixed, and the support position of the arm can be quickly adjusted according to the position of different radiotherapy areas such as the chest, the side of the chest and the head, so as to facilitate radiotherapy of the patient at different positions. At the same time, through the adjustability of the support assembly, the support can be accurately positioned according to the treatment needs to ensure stable support during the treatment process, avoiding the problems of inflexible fixation and difficult adjustment in traditional technologies. This flexibility allows the therapist to quickly respond to different treatment angles and avoid treatment errors caused by improper arm position. When performing head radiotherapy on the patient, by rotating the two support plates 4, the first adjustment rod 6 and the second adjustment rod 12 are driven to rotate with the upper arm plate 15, the second lower arm plate 14 and the first lower arm plate 13 to the top of the bed plate 3 and the two sides of the patient's chest. At this time, the patient's upper arm and lower arm are respectively placed on the top of the upper arm plate 15, the second lower arm plate 14 and the first lower arm plate 13. At this time, the arms will be fixed on both sides of the patient's chest, so as to facilitate the patient's head radiotherapy. At the same time, when the patient's chest and the side of the chest are treated, such as Figure 2 As shown, by rotating the two support plates 4 again, the first adjusting rod 6 and the second adjusting rod 12 are caused to rotate with the upper arm plate 15, the second lower arm plate 14 and the first lower arm plate 13 to both sides of the patient's head. At this time, the patient's upper arm and lower arm are respectively placed on the top of the upper arm plate 15, the second lower arm plate 14 and the first lower arm plate 13. At this time, the patient's arms will be fixed on both sides of the patient's head, thereby facilitating radiotherapy of the patient's chest and chest side. This flexible adjustment not only facilitates radiotherapy of patients in different body positions, but also facilitates medical staff to quickly adjust the bracket, avoiding the traditional trouble of changing beds and brackets.

[0026] like Figure 8 As shown, one side of the movable cylinder 17 is rotatably connected to a knob 16, and one side of the knob 16 is fixedly connected to a screw rod. One end of the screw rod on one side of the three knobs 16 penetrates the side wall of the movable cylinder 17 and contacts one side of the first adjustment rod 6 and the second adjustment rod 12 respectively; by setting the knob 16 and the movable cylinder 17, as shown Figure 8 As shown, due to the different arm lengths of patients, the movable cylinder 17 is caused to move the first small arm plate 13, the second small arm plate 14 and the large arm plate 15 on one side of the second adjusting rod 12 and the first adjusting rod 6 by rotating the knob 16, thereby adjusting the positions of the first small arm plate 13, the second small arm plate 14 and the large arm plate 15, so as to facilitate arm fixation for different patients. When fixing the position of the movable cylinder 17, the knob 16 is rotated to cause one end of the screw to contact one side of the second adjusting rod 12 and the first adjusting rod 6, thereby fixing the position of the movable cylinder 17, and at the same time, fixing the positions of the first small arm plate 13, the second small arm plate 14 and the large arm plate 15, thereby avoiding the problem of arm displacement.

[0027] like Figure 3, Figure 7 and Figure 8 As shown, an adjusting bolt 11 is fixedly connected to one side of the third support plate 10, a connecting bolt 42 is fixedly connected to the inside of the adjusting bolt 11, an end of the connecting bolt 42 away from the adjusting bolt 11 passes through the connection between the first connecting rod 8 and the second connecting rod 9 and is fixedly connected to an adjusting disk 43, a positioning wheel 44 is sleeved on the outside of the connecting bolt 42, a fixing block 46 is fixedly connected to one side of the positioning wheel 44, an end of the fixing block 46 away from the positioning wheel 44 is fixedly connected to one side of the second connecting rod 9, the position of the positioning wheel 44 corresponds to the position of the adjusting disk 43, and a plurality of fixing holes are equidistantly provided in an annular shape inside the positioning wheel 44, an insert rod 45 is slidably connected to the inside of the adjusting disk 43, and one end of the insert rod 45 is slidably connected to the inside of the fixing hole; By providing the first connecting rod 8, the second connecting rod 9 and the adjusting bolt 11, when the bracket assembly is rotated to both sides of the patient's head for use, the height of one end of the second adjusting rod 12 can be raised, such as Figure 3 As shown, the first adjustment rod 6 and the second adjustment rod 12 are in an acute angle shape, so as to facilitate the fixation of the patient's forearm. When the human arms are placed on both sides of the head, it is difficult for the upper arms to contact the top of the upper arm plate 15. At this time, by raising the height of the second adjustment rod 12, the lower arms are fixed, which can increase the patient's comfort and encourage the patient to cooperate with radiotherapy. When the second adjustment rod 12 is rotated, as shown in FIG. Figure 7 and Figure 8 As shown, the second adjusting rod 12 will rotate at one end of the second connecting rod 9 with the adjusting bolt 11 and the first connecting rod 8 through the third supporting plate 10. At this time, since the position of the supporting plate 4 is fixed, as shown in FIG. Figure 3 As shown, the second adjustment rod 12 and the first adjustment rod 6 will be in an acute angle shape, so as to facilitate the fixation of the patient's forearm. At the same time, when positioning the second adjustment rod 12, as shown in FIG. Figure 7 As shown, by inserting the insertion rod 45 into the fixing hole inside the positioning wheel 44, the position of the second adjustment rod 12 is fixed, thereby facilitating the fixation of the patient's forearm. At the same time, through the provision of multiple fixing holes, it is convenient to adjust the second adjustment rod 12 to different angles, thereby facilitating the use of different patients.

[0028] like Figure 6 , Fig. 9 and Fig.10As shown, the clamping assembly includes a fixing plate 26 respectively mounted on the top of the first small arm plate 13 and the second small arm plate 14, the two ends of the fixing plate 26 are respectively connected to the first arc card 30 and the second arc card 31 through an axis rotation, the tops of the first arc card 30 and the second arc card 31 are respectively connected to the connecting plate 29 through an axis rotation, the bottom of the fixing plate 26 is fixedly connected to the insert cylinder 48, the top of the insert cylinder 48 is internally slidably connected to the extrusion bolt 27, the top of the extrusion bolt 27 passes through the inside of the fixing plate 26 and is fixedly connected to the pad 28, and the two connecting plates 29 are respectively connected to the two ends of the top of the pad 28 through an axis rotation; By means of the provided support assembly, the patient's arms can be flexibly fixed, and the support position of the arms can be quickly adjusted according to the positions of different radiotherapy areas such as the chest, chest sides and head, thereby facilitating radiotherapy of patients in different positions. At the same time, through the adjustability of the support assembly, the support can be accurately positioned according to treatment needs to ensure stable support throughout the treatment process, thus avoiding the problems of inflexible fixation and difficulty in adjustment in traditional technologies. This flexibility allows therapists to quickly respond to different treatment angles and avoids treatment errors caused by improper arm position. When performing head radiotherapy on the patient, the support assembly can be rotated to the top of the bed board 3, and the arms will be fixed on both sides of the patient's chest, thereby facilitating the patient's head radiotherapy. At the same time, When treating the patient's chest and chest side, the bracket assembly can be rotated to both sides of the patient's head. At this time, the arms will be fixed on both sides of the patient's head, so as to facilitate radiotherapy of the patient's chest and chest side. When fixing the patient's arm, when the patient's arm is placed on the top of the first forearm plate 13 and the second forearm plate 14, the patient's forearm will press the pad 28 downward by its own gravity. At this time, the pad 28 will move downward with the top of the Velcro 33 and the second arc card 31 through the two connecting plates 29, thereby prompting the tops of the Velcro 33 and the second arc card 31 to approach each other, thereby prompting the Velcro 33 and the second arc card 31 to automatically clamp and fix the human forearm. At this time, the arm will be fixed, so as to facilitate radiotherapy of the patient.

[0029] like Figures 8 to 10 As shown, a return spring 25 is fixedly connected to the inside of the insert tube 48, the top of the return spring 25 is fixedly connected to the bottom end of the extrusion bolt 27, a sticky cable tie 32 is fixedly connected to one side of the top of the second arc card 31, and a Velcro 33 is fixedly connected to one side of the top of the first arc card 30.

[0030] By means of the return spring 25, when the pad 28 is moved downward with the squeezing bolt 27 by gravity, the bottom of the squeezing bolt 27 will squeeze the return spring 25 to contract. Then, when the arm is raised, the return spring 25 will automatically lift the pad 28 upward, so as to facilitate the next use. At the same time, the adhesive strap 32 and Velcro 33 can assist in fixing the arm with the arc card. At the same time, when encountering patients with thick arms, the adhesive strap 32 can be attached to the Velcro 33 for fixation, so as to facilitate the fixation of patients with thick arms.

[0031] like Figures 8 to 10 As shown, the bottoms of the first small arm plate 13 and the second small arm plate 14 are respectively fixedly connected with a positioning cylinder 18, one side of the insertion cylinder 48 is fixedly connected with a positioning cylinder 21, one end of the positioning cylinder 21 is internally slidably clamped with a latch 23, the interior of the positioning cylinder 21 is fixedly connected with a positioning spring 22, the latch 23 is away from the bottom of one end of the positioning spring 22 and has an inclined angle, one end of the positioning spring 22 is fixedly connected to one end of the latch 23, the size of the internal space of the positioning cylinder 18 is adapted to the specifications of the insertion cylinder 48 and the positioning cylinder 21, and the first small arm plate 13 and the second small arm plate 14 have a corresponding internal space. The positioning hole, the position of the opening at the top of the positioning cylinder 18 corresponds to the position of the alignment hole, a positioning hole 24 is opened inside the positioning cylinder 18, the specifications and dimensions of the positioning hole 24 are adapted to the specifications and dimensions of the clamping bolt 23, when the insert cylinder 48 is inserted into the interior of the positioning cylinder 18, the bottoms of the two fixed plates 26 contact the tops of the first small arm plate 13 and the second small arm plate 14 respectively, and the clamping bolt 23 is inserted into the interior of the positioning hole 24, and a connecting cylinder 19 is fixedly connected to one side of the positioning cylinder 18, the interior of the connecting cylinder 19 is connected to the interior of the positioning hole 24, and the interior of the connecting cylinder 19 is slidably clamped with a release bolt 20.

[0032] The provided latch 23 and alignment cylinder 21 can play the role of fixing the clamping assembly. When fixing, the bottom of the insert cylinder 48 is connected to the inside of the positioning cylinder 18 through the inside of the alignment hole. At this time, when the bottom of the latch 23 contacts the top of the positioning cylinder 18, it will automatically shrink due to the action of the positioning spring 22. When the bottom of the insert cylinder 48 moves to the bottom of the inside of the positioning cylinder 18, the position of the latch 23 will correspond to the position of the positioning hole 24. At this time, the latch 23 automatically rebounds due to the action of the positioning spring 22, prompting one end of the latch 23 to be stuck in the positioning hole 24. 4, thereby causing the position of the insert tube 48 to be fixed, and at the same time, the position of the clamping assembly is fixed. At the same time, when the bracket assembly is rotated to both sides of the patient's chest and radiotherapy is performed on the patient's arm at a later time, the release bolt 20 can be pressed to cause one end of the release bolt 20 to push the clamping bolt 23 to shrink into the interior of the alignment tube 21, thereby causing the clamping assembly to move out of the top of the first small arm plate 13 and the second small arm plate 14, so that it is convenient for the patient to directly place his arm on the top of the first small arm plate 13, the second small arm plate 14 and the large arm plate 15, thereby facilitating the radiotherapy of the patient's arm.

[0033] like Figures 1 to 5 As shown, the driving assembly includes a driving wheel 34 and a driven wheel 35 which are rotatably connected to the inside of one end of the bed board 3. The tops of the driving wheel 34 and the driven wheel 35 are fixedly connected to the bottoms of the two support plates 4 respectively through shafts passing through the top of the bed board 3. The driving wheel 34 and the driven wheel 35 are connected by a cross-belt drive.

[0034] The drive assembly is provided with a fast adjustment mechanism, which can adjust the position of the support assembly in one step, avoiding the tedious process of changing the bed position due to adjusting the arm position in traditional technology. The treatment staff only needs to operate the drive assembly to quickly adjust the arm position, saving time and improving operation efficiency. At the same time, the flexibility of the drive assembly not only allows the support assembly to quickly switch the support position, but also ensures that the support will not be displaced during the entire treatment process, thereby eliminating the treatment error caused by arm displacement. When rotating the support assembly, first rotate the driving wheel 34, prompting the driving wheel 34 to rotate with the driven wheel 35 through the cross belt. At this time, the cross belt is used to prompt the driving wheel 34 and the driven wheel 35 to rotate synchronously with the two support plates 4. Figure 2 As shown, it is convenient for medical personnel to adjust the position of the bracket assembly in one step, thereby improving work efficiency.

[0035] like Figures 1 to 5As shown, the bottom of the bed board 3 is fixedly connected to a fixing column 36, the outside of the fixing column 36 is fixedly connected to a positioning plate 37, the bottom of the driving wheel 34 is fixedly connected to a connecting shaft 41, the bottom end of the connecting shaft 41 passes through the bed board 3 and the inside of the fixing column 36 and is fixedly connected to an adjusting wheel 39, the inside of the adjusting wheel 39 is slidably engaged with a positioning rod 40, the inside of the positioning plate 37 is symmetrically provided with two T-shaped holes 38, one end of the positioning rod 40 is fixedly connected to a T-shaped block, and the specifications and dimensions of the T-shaped holes 38 are adapted to the specifications and dimensions of the T-shaped blocks.

[0036] The fixed column 36, T-shaped hole 38 and adjusting wheel 39 are provided to facilitate the use of medical staff. When rotating the driving wheel 34, the adjusting wheel 39 is first rotated to cause the connecting shaft 41 to rotate with the driving wheel 34. Then, when positioning the driving wheel 34 and the bracket assembly, the T-shaped block at one end of the positioning rod 40 is inserted into one side of the T-shaped hole 38 and rotated, so that the T-shaped block at one end of the positioning rod 40 and the T-shaped hole 38 are in a cross shape, thereby causing the position of the positioning rod 40 to be fixed, and the position of the adjusting wheel 39 is fixed, thereby facilitating the use of medical staff. It should be noted here that, if the position of the bracket assembly needs to be adjusted frequently in the later stage, the motor can be used to drive the driving wheel 34 to rotate, thereby saving manpower and making the position adjustment faster, simpler and more convenient. Figure 1 As shown, it is the initial state, and the adjustment wheel 39 and the driving wheel 34 are located on one side of one end of the seat plate 2. This can avoid the problem that the structure adjacent to the adjustment wheel 39 and the driving wheel 34 affects the movement of the bed board 3 when the bed board 3 is moved during radiotherapy.
