Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a receiving plate component for radiation therapy equipment. Background Art

[0002] In radiation therapy equipment, such as Figure 1 As shown, two X-Ray light sources 1 are symmetrically arranged on both sides of the treatment head 6, and the irradiation directions of the two X-Ray light sources 1 are 90" cross-shaped; during treatment, two X-Ray receiving plates 2 are arranged behind the patient treatment chair 3. The patient treatment chair 3 is generally adjustable and controlled and supported by a multi-degree-of-freedom mechanical arm 4. The X-Ray receiving plate 2 is generally installed on the ceiling using a hanging bracket, which is expensive, difficult to install and inconvenient to maintain; there is also a method of controlling the X-Ray receiving plate 2 to adjust between the working position and the storage position by a horizontal rotation structure, such as the X-Ray receiving plate adjustment device and particle therapy equipment disclosed in the utility model patent with publication number CN 218607761U; but in practice, it is found that although the control method of the horizontal rotation structure is convenient for maintenance, the X-Ray receiving plate 2 will sweep a large area when it rotates horizontally, making the overall equipment occupy a large area and increasing the treatment area.

[0003] Therefore, it is necessary to design a new X-Ray receiving board control structure. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a receiving plate assembly for a radiation therapy device, which has a small operating space for the device and a small space occupied after being stored, and is convenient for maintenance.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a receiving plate assembly for a radiation therapy device, comprising an X-Ray receiving plate and a receiving plate supporting mechanism, wherein the receiving plate supporting mechanism comprises a turntable, a second supporting rod, a movable guide rail and a first supporting rod;

[0006] The turntable has a vertically arranged output shaft;

DETAILED DESCRIPTION

[0027] like Figure 1 and Figure 2 As shown, a receiving plate assembly for a radiation therapy device includes an X-Ray receiving plate 2 and a receiving plate supporting mechanism 5. The X-Ray receiving plate 2 is a prior art, and its structure is not described here.

[0028] The receiving plate support mechanism 5 includes a turntable 53, a second support rod 54, a movable guide rail 51 and a first support rod 52. The turntable 53 has a vertically arranged output shaft 55, and a device for driving the output shaft 55 to rotate, such as a motor, is installed in the turntable 53. The transmission and assembly relationship between the motor and the output shaft 55 is a prior art and will not be described in detail here.

[0029] The movable guide rail 51 is horizontally arranged, and extends between the storage position and the working position of the X-Ray receiving plate 2; it is preferably a linear guide rail.

[0030] The first support rod 52 is vertically arranged, and the X-Ray receiving plate 2 is fixed on the upper end thereof. The lower end of the first support rod 52 cooperates with the movable guide rail 51 and can slide along the movable guide rail 51.

[0031] The second support rod 54 is arranged horizontally, one end of which is fixedly connected to the output shaft, and the other end of which is rotatably connected to the first support rod 52. The second support rod 54 is a retractable rod, for example Figure 4The second support rod 54 shown includes a multi-stage telescopic cylinder 541, with a first connecting seat 542 and a second connecting seat 543 respectively provided at both ends. The first connecting seat 542 is provided with a rectangular hole for clamping with the output shaft 55; the second connecting seat 543 is provided with a circular hole for rotationally connecting with the first support rod 52.

[0032] The second support rod 54 rotates under the drive of the output shaft 55, thereby pushing the first support rod 52 to move along the movable guide rail 51; the first support rod 52 drives the X-Ray receiving plate 2 to move back and forth between the storage position and the working position. Since the guide path of the movable guide rail 51 is a straight line, the moving path of the first support rod 52 and the X-Ray receiving plate 2 can be limited to a specific range. Compared with the existing hoisting structure and horizontal rotation structure, it can not only reduce the treatment area required by the equipment, but also the ground-mounted structure has good maintenance performance.

[0033] The movable guide rail 51 can adopt any existing guide rail form on the market, such as an "I"-shaped guide rail, an inverted "T"-shaped guide rail, etc., as long as it can guide the first support rod 52. In order to simplify the overall structure of the device and optimize the treatment space, it is recommended to set the movable guide rail 51 on the ground. If it protrudes from the ground, it may hinder the movement of equipment such as wheelchairs. Therefore, it is preferably embedded in the foundation, and its upper side is in the same plane as the ground.

[0034] In order to prevent the first support rod 52 from getting stuck due to debris on the ground during the movement, the inventors have also optimized and improved the structure of the moving guide rail 51. Figure 3 As shown, the movable guide rail 51 includes an upper cover plate 511, a first side plate 512, a second side plate 515 and an inner guide bar 517; wherein the inner guide bar 517 is fixedly arranged on the first side plate 512, and the upper cover plate 511 is also fixedly connected to the first side plate 512 and is located on the upper side of the inner guide bar 517 to shield the inner guide bar 517. The upper cover plate 511 can be set to be flush with the ground. The second side plate 515 is parallel to the first side plate 512 and is arranged at intervals, and the inner guide bar 517 and the upper cover plate 511 are located therebetween, and a connecting window is provided between the upper cover plate 511 and the second side plate 515, and the first support rod 52 passes through the connecting window and extends between the first side plate 512 and the second side plate 515 and is slidably connected to the inner guide bar 517 through a slider 518.

[0035] Furthermore, there is a material receiving plate assembly between the first side plate 512 and the second side plate 515. The material receiving plate assembly is located at the lower side of the inner guide bar 517 and includes an inclined bottom plate 513, a connecting plate 514 and a horizontal bottom plate 516. The three are connected in sequence. The inclined bottom plate 513 is arranged directly below the inner guide bar 517 and is fixedly connected to the first side plate 512. The horizontal bottom plate 516 is directly opposite to the connecting window and is fixedly connected to the second side plate 515. In this way, even if the debris on the ground falls into the movable guide rail 51, it will fall to the horizontal bottom plate 516 for temporary storage, and will not affect the movement of the first support rod 52, thereby achieving a stable guiding effect of the movable guide rail 51.

[0036] The guide surface of the inner guide bar 517 and the slider 518 that cooperate with each other is preferably a cylindrical surface, which allows smooth guidance and movement. The movable guide rail 51 can be provided with a positioning structure at the storage position and the working position corresponding to the X-Ray receiving plate 2 to limit the two extreme positions of the slider 518, which can also be achieved by controlling the rotation angle of the second support rod 54. Whether it is setting a positioning structure or controlling the rotation angle, it is a prior art, and the inventor has not made further improvements, so it will not be described in detail here.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
