TECHNICAL FIELD

[0001] The present application relates to the technical field of customized phantom, in particular to a printer for phantom customization. BACKGROUND

[0002] In the process of radiotherapy for radiotherapy patients, a radiotherapy machine is generally used for operation, and the treatment plate inside the radiotherapy machine needs to be stable in the process of use, so as to ensure the normal position of the targeted tumor. The two commonly used fixing device technologies can be applied to most patients, but the patients need to lie flat on the treatment plate. However, in clinical practice, some patients cannot lie flat due to forced position caused by severe pain or severe spinal deformity, which leads to the failure of radiotherapy. Moreover, the existing technology needs to make a fixing device (i.e. a thermoplastic phantom or a vacuum pad) in the same positioning system before obtaining the tomographic image by CT positioning. The increase of working steps will inevitably increase the probability of errors. In the process of printing the phantom by using the existing 3D printer, the existing equipment can only scan and print layer by layer, but the details of the small radius and turning part of the phantom may not be fine, the nozzle of the printer needs to be replaced, the operation steps are complicated, and the operation burden of the personnel is increased.

[0011] Preferably, the cleaning assembly comprises a gas tank, the back of the driving assembly is fixedly connected with the side of the gas tank, both ends of the gas tank are provided with gas pipes, and one end of the gas pipe is provided with a ventilation mechanism.

This reduces the number of manual steps required, allows for more precise operation during printing, and ensures that the printed model fits the person's posture more effectively, thus maintaining the person's posture and achieving a stable effect.

[0019] By using the entire device in conjunction with a CT scanner, this invention offers a significant advantage over existing technologies. Existing technologies require the pre-fabrication of a fixation device (thermoplastic phantom or vacuum pad) within the same positioning system before acquiring CT tomographic images. This increased workload inevitably raises the probability of errors. This invention effectively combines 3D printing technology with CT tomographic scanning to obtain precise patient location and body shape information, resulting in a more accurate and fitting phantom. Patients can choose more comfortable and flexible positions during treatment, avoiding any impact on treatment due to forced postures or limb deformities. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-14 The present invention provides a technical solution:

[0037] Example 1,

[0038] A printer for customizing body models includes: a housing 1, which is a square structure with a hollow interior, and a drive assembly 2 is provided on the side of the housing 1;

[0039] Replace component 3, which is located at the bottom of drive component 2. Replacing component 3 can change the jet flow rate.

[0040] Cleaning component 4 is located on the side of replacement component 3 and can clean the fluid inside replacement component 3.

[0041] Inclined component 5 is located inside the outer shell 1 and is in contact with the bottom of the mold body.

[0042] The replacement component 3 includes a rotating shaft 31. The interior of the drive component 2 is connected to the outer edge of the rotating shaft 31. The slide 23 has a drive structure inside that can drive the rotating shaft 31 to rotate, thereby controlling the rotating shaft 31 to drive the replacement of the connecting frame 32 and the nozzle 33. One end of the rotating shaft 31 is connected to three sets of connecting frames 32. The front of the connecting frame 32 can support and fix the heating component and the fan. The side of the connecting frame 32 is rotatably connected to the nozzle 33. The nozzle 33 is set to three sets and the nozzles 33 are evenly arranged. The orifice sizes of the nozzles 33 are arranged in an arithmetic progression. One end of the rotating shaft 31 is connected to a replacement mechanism 34. The replacement mechanism 34 can realize the replacement of the printing material connection. The replacement component 3 can realize the change of the orifice size of the nozzle 33, thereby realizing fine operation and avoiding the situation that the production time of the mold is increased due to the use of only small nozzles 33.

[0043] The replacement mechanism 34 includes a turbine 341, the side of which is rotatably connected to the side of a worm gear 342. The side of the worm gear 342 is rotatably connected to the inside of a support frame 343 via a shaft. A fixed wheel 344 is fixedly connected to the side of the worm gear 342. A transmission wheel 345 is rotatably connected to the side of the fixed wheel 344. The side of the transmission wheel 345 is rotatably connected to one end of a transmission rod 346. When the rotating shaft 31 rotates 120 degrees, it drives the turbine 341 to rotate. At the same time, the thread on the side of the turbine 341 drives the worm gear 342 and the fixed wheel 344 to rotate together. Then, by utilizing the contact between the fixed wheel 344 and the side of the transmission wheel 345, the transmission wheel 345 can drive the transmission rod 346 to achieve a traction effect.

[0044] The bottom of the drive assembly 2 is connected to a base 347. One end of the transmission rod 346 is rotatably connected to the side of the slide tube 348. A sliding plate 349 is fixedly connected to the side of the slide tube 348. A clamping wheel 3410 is rotatably connected inside the slide tube 348. A clamping piece 3411 is fixedly connected to the side of the clamping wheel 3410. A rack tooth 3412 is fixedly connected to the inner wall of the base 347. One end of the rack tooth 3412 is fixedly connected to the side of the limiting block 3413. The side of the limiting block 3413 is fixedly connected to one end of the telescopic spring 3414. During rotation, the transmission rod 346 drives the slide tube 348 to reciprocate at the top of the base 347. At the same time, the sliding plate 349 limits the running position. The clamping wheel 3410 has a semi-circular tooth on its side. When the semi-circular tooth contacts the side of the rack tooth 3412, the slide moves... During the process, due to the large width of the clamping piece 3411, it will contact the side of the printing material. When the clamping wheel 3410 contacts the last set of teeth of the toothed bar 3412, the clamping piece 3411 will squeeze the printing material in contact with the center of the slide tube 348. Since one end of the toothed bar 3412 is movably connected, and the transmission rod 346 moves backward, the locking tooth and the limiting block 3413 move backward together and compress the telescopic spring 3414, thereby expelling one end of the printing material and achieving the separation function. When the connecting frame 32 continues to rotate and the small vertical nozzle 33 is replaced to the bottom, the transmission rod 346 will return to its position. The process of using the principle of reverse pushing makes the printing material re-inserted into the back of the new set of connecting frames 32, thereby realizing the replacement of printing material during the replacement of nozzle 33.

[0045] According to the above embodiments, Embodiment Two

[0046] The cleaning component 4 includes an air tank 41. The back of the drive component 2 is fixedly connected to the side of the air tank 41. The air tank 41 has air pipes 42 at both ends. One end of the air pipe 42 is provided with a ventilation mechanism 43. The inside of the air tank 41 is under positive pressure. Gas can be delivered to the air pipe 42 through the air tank 41, and excess printing material can be discharged through the ventilation mechanism 43.

[0047] The ventilation mechanism 43 includes an outer cover 431. One end of the air pipe 42 is fixedly connected to the side of the outer cover 431. A connecting cover 432 is slidably connected to the inner wall of the outer cover 431. A slot 433 is provided in the center of the connecting cover 432. There is a gap between the connecting cover 432 and the inner wall of the outer cover 431, and the space is supported by a spring. A vent hole 434 is provided on the side of the connecting cover 432. An air valve 435 is provided inside the outer cover 431. Because the bottom end of the connecting cover 432 has an arc-shaped structure, when the bottom end of the nozzle 33 contacts the air pipe... When the side of the connecting cover 432 is pressed, a squeezing process is formed on the connecting cover 432. At the same time, the process of pressing down the connecting cover 432 will connect the vent 434 and the valve 435, so that the gas inside the gas tank 41 can enter the back of the connecting cover 432. When one end of the nozzle 33 is embedded in the inside of the slot 433, high-pressure gas will enter through the nozzle 33 nozzle end nozzle, and then the residual printing material inside the nozzle 33 will be blown out from the front of the connecting frame 32, so as to avoid the residual material clogging the nozzle 33.

The side of the slide plate 58 is slidably connected to the inner wall of the track 59. The motor 54 is turned on by computer control, which drives the threaded shaft 55 to rotate. The thread on the side of the threaded shaft 55 drives the lifting shaft 56 to move up and down. At the same time, the connection between the pulley 57 and the slide plate 58 allows the slide plate 58 to slide inside the track 59. The top of the track 59 is fixedly connected to the bottom of the platform 53, which allows control of the tilt angle of each corner of the platform 53.

[0053] For custom-made body models, the patient is first placed in a large-aperture positioning CT scanner. Under the guidance of a doctor, the patient can choose a comfortable position that meets the treatment needs. The CT scan will then acquire images. The tomographic images acquired by the CT scan will be reconstructed in 3D to extract the patient's body surface position information. Finally, the body surface position information will be converted into a format that can be recognized by a 3D printer. A fixation device that can highly adapt to the patient's body shape and position will be made through 3D printing, which is the fixation body model.
