[0001] The present invention belongs to the technical field of radiotherapy equipment, and in particular relates to a bracket for radiotherapy equipment. Background Art

[0002] Radiotherapy equipment consists of a treatment head and an applicator, whose central axes are aligned. The treatment head emits and accelerates the electron beam, while the applicator forms the irradiation field so that the dose distribution produced by the electron beam at the patient's lesion closely matches the shape of the lesion while minimizing the radiation dose to surrounding tissues. During intraoperative radiotherapy, one end of the applicator must be aligned with the treatment head and the other with the patient's lesion. The applicator must be fixed to prevent positional shifts that could affect treatment effectiveness.

[0003] The prior art provides a bracket mounted on the operating table to secure the applicator during intraoperative radiotherapy. However, the location of the patient's lesion at which the applicator is aimed may vary between treatments. In such cases, the entire bracket must be moved to adjust the applicator's position. This movement poses the risk of squeezing or injuring the patient. This related technology presents a technical problem of cumbersome operation. Summary of the Invention

[0035] DETAILED DESCRIPTION

[0036] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0037] The following describes a support 100 for a radiotherapy device according to the present invention with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the radiotherapy equipment includes an applicator for forming a radiotherapy irradiation field, and the bracket 100 of the radiotherapy equipment includes a first rod 1, a second rod 2, a first connecting member 3, a second connecting member 4, a third connecting member 5, a fourth connecting member 6, a fifth connecting member 7 and a first supporting member 8. The second rod 2 is slidably engaged with the first rod 1, and the sliding direction is consistent with the length direction of the second rod 2. The first connecting member 3 is sleeved on the first rod. The second connecting member 4 is arranged at one end of the second rod. The third connecting member 5 is rotatably connected to the second connecting member 4. The fifth connecting member 7 is arranged on the first connecting member 3 and is used to connect to the operating table. The first supporting member 8 is arranged on the third connecting member 5 and is used to place the applicator.

[0039] Specific process of adjusting the applicator position:

[0040] The position of the first supporting member 8 is adjusted along the length of the first rod 1 by sliding with the first connecting member 3; the position of the first supporting member 8 is adjusted with the first rod 1 as the rotation axis by rotating with the first connecting member 6; the position of the first supporting member 8 is adjusted along the length of the second rod 2 by sliding with the fourth connecting member 6; the position of the first supporting member 8 is adjusted with one end of the second rod 2 as the rotation center by rotating with the second connecting member 4 and the third connecting member 5; after the position adjustment of the first supporting member 8 is completed, the applicator is placed on the first supporting member 8 to complete the position adjustment of the applicator. During the entire position adjustment process, the fifth connecting member 7 remains connected to the operating table, and only the various components of the bracket need to be adjusted to achieve flexible adjustment in multiple dimensions, thereby eliminating the need to move the entire bracket 100 to adjust the position of the applicator, thereby simplifying the position adjustment operation steps.

[0041] For the convenience of description below, the technical solution in which the first rod 1 and the second rod 2 are perpendicular to each other and both are in the vertical plane is taken as a specific embodiment, and the length direction of the first rod 1 is specified as the up-down direction, the length direction of the second rod 2 is specified as the left-right direction, and the extension direction of the straight line perpendicular to the first rod 1 and the second rod 2 is specified as the front-back direction.

[0042] In an embodiment of the present invention, a wheel disc 9 is provided on the first connecting member 3, and a rack is provided on the first rod 1. Rotating the wheel disc 9 can make the first rod 1 slide along the length direction. A first locking member 11 for locking or releasing the first rod 1 is provided on the first connecting member 3. The wheel disc 9 and the rack are self-locking to prevent the first rod 1 from falling due to gravity.

[0043] Specifically, the first connecting member 3 is provided with a through hole extending in the vertical direction, and a linear bearing is provided on the inner wall of the through hole. The first connecting member 3 is connected to the first rod 1 via the linear bearing. The rotating wheel 9 is connected to the rack via multiple gears, and the wheel drives the gears connected to the rack to achieve vertical sliding of the first rod 1. When the first connecting member 3 is adjusted to a preset position, the linear bearing is locked by a first locking member to limit the sliding of the first connecting member 3. The first connecting member 3 can be connected to the first rod 1 not only by a linear bearing, but also by a transmission method such as a gear rack, a screw rod, and a screw nut to achieve relative movement between the first connecting member 3 and the first rod 1.

[0044] Furthermore, the travel of the ball in the linear bearing can be set to limit the first rod 1 from separating from the first connector 3. Alternatively, an end stopper 10 can be provided at the lower end of the first rod 1 to prevent the first rod 1 from separating from the first connector 3. The size of the end stopper 10 needs to be larger than the size of the through hole in the first connector 3. The end stopper 10 can be a spherical, cubic, or other shaped component. The end stopper 10 not only has a limiting function but also makes it easier for the operator to grasp it.

[0045] In an embodiment of the present invention, the fourth connecting member 6 is rotatably connected with the straight line where the first rod 1 is located as the rotation axis, and the fourth connecting member 6 is provided with a second locking member 12 for locking or releasing the first rod 1. The second rod 2 passes through the fourth connecting member 9, and the fourth connecting member 9 is provided with a third locking member 13 for locking or releasing the second rod 2.

[0046] Specifically, the bottom of the fourth connecting member 6 is a rotatable disk, which is fixedly connected to the first rod 1. A bearing is disposed within the disk, allowing the fourth connecting member to rotate about the line on which the first rod 1 is located as the rotation axis. When the fourth connecting member 6 rotates about the first rod 1 to a preset position, the disk is locked by a second locking member to restrict the rotation of the fourth connecting member 6. The fourth connecting member is provided with a through hole extending in the left-right direction, and the inner wall of the through hole is provided with a linear bearing. The second rod 2 is connected to the linear bearing. The linear bearing is provided to restrict the second rod 2 from sliding only in the left-right direction. When the second rod 2 is adjusted to the preset position, the linear bearing is locked by a third locking member to restrict the sliding of the second rod 2.

[0047] Furthermore, the second rod 2 can be limited from being separated from the fourth connecting member by setting the stroke of the ball in the linear bearing, or the second rod 2 can be prevented from being separated from the fourth connecting member by setting an end limiter 10 at the left end of the second rod 2. The size of the end limiter 10 needs to be larger than the size of the through hole on the fourth connecting member.

[0048] In an embodiment of the present invention, one end of the second connecting member 4 is connected to the universal ball head of the third connecting member 5, and the other end is connected to the second rod member 2. The inclination angle range of the universal ball head is 0° to 90°, and the fourth locking member 14 is used to lock the second connecting member 4 to clamp the universal ball head of the third connecting member 5.

[0049] Specifically, the inclination angle of the universal joint is selected to be 90° and the universal joint is limited to rotation within the horizontal plane. That is, the third connecting member 5 can rotate forward or backward by a maximum of 90°. When the third connecting member 5 is adjusted to the preset position, the fourth locking member locks the second connecting member 4 against the universal joint to restrict the rotation of the third connecting member 5.

[0050] In an embodiment of the present invention, a slot is formed on the fifth connecting member 7, the notch of the slot faces the operating bed, and the operating bed is engaged in the slot. When the fifth connecting member 7 is adjusted to a preset position, the sliding of the fifth connecting member 7 is restricted by locking the fifth locking member 15.

[0051] Specifically, a strip-shaped protrusion is generally provided on the side of the operating bed. The strip-shaped protrusion and the slot on the fifth connecting member 7 extend in the same direction. The strip-shaped protrusion is engaged in the slot, thereby realizing the connection between the bracket 100 and the operating bed.

[0052] Furthermore, the fifth connecting member 7 slides with the strip-shaped protrusion along the length of the strip-shaped protrusion, thereby adjusting the connection position between the bracket 100 and the operating table. A fifth locking member 15 is provided on the fifth connecting member 7. When the fifth connecting member 7 is adjusted to a preset position, the fifth locking member presses against the strip-shaped protrusion to prevent the fifth connecting member 7 from sliding.

[0053] In an embodiment of the present invention, the first supporting member 8 includes an annular disk, and the applicator includes an annular portion and a cylindrical portion that are coaxially connected. The bottom surface of the annular portion abuts the top surface of the annular disk, and the outer circumferential wall of the cylindrical portion abuts the inner circumferential wall of the annular disk. A plurality of mounting holes are circumferentially spaced apart on the annular disk, and a fastener 17 threadedly engaged with the mounting hole 16 is provided on the third connecting member 5. The fastener 17 is used to connect the third connecting member 5 and the annular disk.

[0054] In an embodiment of the present invention, a circular groove is formed on the top surface of the annular disk. The diameter of the circular groove matches that of the annular portion, and the depth matches the thickness of the annular portion. After the applicator is placed, the annular portion engages with the groove, thereby improving the stability of the applicator. The annular portion is circumferentially arranged with multiple locking bolts 18 radially extending therethrough. The locking bolts 18 threadably engage with the annular portion and radially penetrate the annular portion. When the applicator is placed on the annular portion, tightening the locking bolts 18 presses against the cylindrical portion to secure the applicator, thereby improving the stability of the applicator.

[0055] In an embodiment of the present invention, arc-shaped holes are provided on the third connecting member 5 at intervals, and the arc-shaped holes and the plurality of mounting holes 16 are located on the same circumference with the center of the annular disk as the center of the circle. The fastener 17 is arranged through the arc-shaped hole and slides with the side wall of the arc-shaped hole. The size of the end of the fastener 17 away from the annular disk is larger than the size of the arc-shaped hole, and the number of the mounting holes 16 corresponding to the arc-shaped hole is not less than the number of the fasteners 17.

[0056] Specifically, the third connecting member 5 is an arc-shaped component with the center of the annular disk as the center of the circle. There are three arc-shaped holes with the same curvature. The three arc-shaped holes are evenly spaced. A fastener 17 is correspondingly provided in each arc-shaped hole, and the fastener 17 slides with the side wall of the arc-shaped hole.

[0057] Furthermore, the third connecting member 5 rotates in the horizontal plane through the universal ball head. When the third connecting member 5 is rotated to any angle and the applicator is placed, the fasteners 17 in each arc hole can be fastened to the corresponding mounting hole 16 by sliding, thereby completing the position fixation of the first supporting member 8.
