Description

TECHNICAL FIELD

[0001] The application relates to the technical field of treatment heads, in particular to a treatment head convenient to disassemble and assemble. BACKGROUND

[0002] A proton heavy ion therapeutic instrument is a cutting-edge radiotherapy system based on a synchrotron, which realizes precise metering and throwing of tumors by accelerating protons or heavy ions. The treatment head is an important component of the therapeutic instrument, and the particle beam flows from the position of the treatment head.

[0003] The existing treatment head comprises a beam head, an imaging plate and a plurality of assembling plates. When a worker installs the therapeutic instrument, the worker installs the beam head to the position of the head of the therapeutic instrument, then installs the imaging plate on both sides of the beam head, and installs the assembling plates to the circumferential sides of the beam head and the imaging plate, and fixes the assembling plates by screws. When the worker later maintains the treatment head, the worker removes the screws and then removes the assembling plates, and then separately maintains the beam head and the imaging plate.

[0004] When the above treatment head is later maintained, the worker needs to remove a large number of screws, so that the maintenance process is complicated, and there is room for improvement. CONTENT OF THE INVENTION

[0005] In order to reduce the number of screws that the worker needs to remove when the treatment head is later maintained, and simplify the maintenance process, the application provides a treatment head convenient to disassemble and assemble.

[0006] The application provides a treatment head convenient to disassemble and assemble, which adopts the following technical scheme:

[0007] The treatment head convenient to disassemble and assemble comprises a connecting frame, a beam head arranged at one end of the connecting frame, and a shell arranged on both sides of the beam head, the shells arranged on both sides of the beam head are detachably fixed, the two sides of the shell away from the beam head are arranged in an inclined manner, the imaging plates are arranged on the two sides of the shell away from the beam head, and the imaging plates are arranged at the positions of the inner walls of the shell arranged in an inclined manner.

[0008] By adopting the above technical scheme, when a worker uses the therapeutic instrument, the worker installs the connecting frame to the position of the head of the therapeutic instrument, then installs the beam head to the end of the connecting frame away from the head, at this time the worker installs the two shells to both sides of the beam head in alignment, and the worker installs the imaging plates to both sides of the shell. When the worker later maintains the therapeutic instrument, the worker removes the two shells, at this time the worker can directly maintain the beam head. This arrangement reduces the number of screws that the worker needs to remove when the treatment head is later maintained, and simplifies the maintenance process.

[0009] Optionally, the connecting frame comprises a base frame and a rotating shaft rotatably connected to the base frame, and the beam head is fixed to a side of the rotating shaft away from the base frame.

[0010] By adopting the above technical scheme, when the staff uses the treatment machine, the staff can rotate the beam head through the rotating shaft, so that the angle of the beam head can be adjusted, facilitating the staff to further position the treatment area.

[0011] Optionally, the beam head comprises an emitting head and an extension member fixed to the rotating shaft, and the emitting head is installed on a side of the extension member away from the rotating shaft.

[0012] By adopting the above technical scheme, the staff can control the position of the emitting head, so that the emitting head is located at a position more suitable for beam treatment, and the working range of the emitting head is further improved.

[0013] Optionally, the imaging plate is slidably connected to the inner wall of the shell, and the imaging plate can slide along the tilting direction of the shell.

[0014] By adopting the above technical scheme, the sliding of the imaging plate and the extension of the emitting head work together to improve the treatment effect of the treatment machine and simplify the operation process of the staff.

[0015] Optionally, the outer wall of the shell is fixed with a blocking plate, and one end of the rotating shaft abuts against the inner wall of the blocking plate.

[0016] By adopting the above technical scheme, the blocking plate improves the stability of the connection between the shell and the rotating shaft, and reduces the impact received by the device, thereby improving the stability of the internal structure.

[0017] In summary, the present application has at least one of the following beneficial technical effects:

[0018] 1. When the staff uses the treatment machine, the staff installs the connecting frame to the position of the machine head, and fixes the beam head to the end of the connecting frame away from the machine head. At this time, the staff installs the two shells to the side walls of the beam head respectively, and installs the two imaging plates to the inner walls of the two sides of the shell. When the staff maintains the treatment machine later, the staff dismounts the two shells, and then carries out maintenance work on the beam head and the imaging plate. This setting reduces the number of screws that the staff needs to dismount when maintaining the treatment head, and simplifies the maintenance process.

[0019] 2. The staff can change the beam emission height of the emitting head through the extension member, and can change the beam emission angle of the emitting head through the rotating shaft. At this time, the staff slides the imaging plate out of the shell. This setting changes the working range of the treatment machine, and facilitates the operation of the staff.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS

[0023] The following will be described in detail in combination with the accompanying Figures 1-2 The application will be further described in detail.

[0024] The embodiment of the application discloses a treatment head convenient to disassemble.

[0025] Reference Figure 1 A treatment head convenient to disassemble comprises a connecting frame 1 installed on a machine head, a beam head 2 installed on the end of the connecting frame 1 away from the machine head, and shells 3 which can be detachably fixed on both sides of the beam head 2. In the embodiment of the application, the overall structures of the two shells 3 are the same and are fixed by screws. The shells 3 are funnel-shaped. The side of the shorter inner diameter of the shell 3 is fixed with the inner wall of the connecting frame 1. The inner walls of both sides of the shell 3 are slidably matched with imaging plates 4. The imaging plates 4 slide in the direction of the inclination angle of the shell 3.
