Description

Technical Field

[0001] The present invention relates to the field of 3D printing devices, and in particular to a 3D printing device for a post-loading applicator for treating cervical cancer. Background Art

[0002] Applicators (also called radiation sources, radiotherapy heads or radiosurgery devices) are devices used for medical radiation therapy, mainly used for radiotherapy and radiosurgery. These devices usually contain one or more radioactive isotopes and are used to treat various cancers and other diseases. With the development of 3D printing technology, it has also played an important role in the manufacture and maintenance of applicators.

[0003] Therefore, based on the existing applicator 3D printing device, in actual use, the working principle of its printing is to solidify the biocompatible resin through the refraction of ultraviolet laser for printing. However, in the process of ultraviolet laser refraction, if the elastic layer of the resin tank is worn, the ultraviolet laser will be astigmatized, which will cause the biocompatible resin to have residues such as solidified resin debris and precipitated pigments during the curing process, further affecting the refraction of the ultraviolet laser, causing refraction deviation or incomplete curing, seriously affecting the safety of the printed applicator. At the same time, after printing is completed, violent demolding of the applicator will also cause damage to the applicator.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a 3D printing device for a post-loading applicator for the treatment of cervical cancer.

[0031] In a typical implementation of the present application, Figure 1-9 As shown, a 3D printing device for a post-loading applicator for treating cervical cancer comprises:

[0032] A workbench 1, the workbench 1 comprises a cleaning table 40, and a cleaning machine 2 is placed on the top of the workbench 1;

[0033] The printer 3 is used for printing the source applicator. The printer 3 includes a printing shell 8 placed on the top of the workbench 1. The interior of the printing shell 8 is slidably connected to a lifting platform 7. The bottom of the inner wall of the printing shell 8 is also fixedly plugged with a resin tank 6. The resin tank 6 is used to contain a biocompatible resin;

[0034] The demoulding mechanism 4 is used to construct a platform for the printing source applicator. The demoulding mechanism 4 includes a building platform 9 fixedly connected to the bottom of the lifting platform 7. The bottom of the building platform 9 is fixedly connected to an aluminum plate 10. Three bending plates 12 are movably inserted inside the aluminum plate 10. Both ends of the three bending plates 12 are rotatably connected to extrusion rods 13. Both sides of the building platform 9 are fixedly connected to limit frames 11. Two extrusion rods 13 are slidably connected to the inside of the adjacent limit frames 11.

[0035] The demolding mechanism 4 also includes a demolding plate 14 rotatably connected to the outside of the extrusion rod 13, a plurality of card slots 17 are opened on one side of the demolding plate 14, a demolding sleeve 15 is slidably connected to the outside of the demolding plate 14, a squeezing knob 21 is threadedly screwed on one side of the demolding sleeve 15, an squeezing plate 20 is rotatably connected to the bottom of the squeezing knob 21, the squeezing plate 20 is slidably connected to the inside of the demolding sleeve 15, an squeezing spring 19 is fixedly connected to the bottom of the squeezing plate 20, a card block 18 is fixedly connected to the bottom of the squeezing spring 19, and the card block 18 is adapted to the plurality of card slots 17.

[0036] Both sides of the demolding sleeve 15 are fixedly connected to the limiting rod 22, the outer part of the limiting rod 22 is rotatably sleeved with a telescopic belt 16, and the other end of the telescopic belt 16 is rotatably sleeved on the outer part of the limiting frame 11. A driving groove 23 is opened on one side of the demolding sleeve 15, and the top of the demolding plate 14 is fixedly connected to a return spring 24, and the top of the return spring 24 is fixedly connected to the top of the inner wall of the demolding sleeve 15.

[0037] By setting up the above-mentioned structure, the damage caused by demolding the source applicator can be minimized. Specifically, after the source applicator is printed using the printer 3, the source applicator is now adhered to the bottom of the aluminum plate 10. At this time, the printer 3 is opened, and both hands hold the limit frames 11 on both sides of the building platform 9, and the building platform 9 is separated from the lifting platform 7. At this time, the building platform 9 is moved to a safe position for demolding to prevent the source applicator from falling and bumping during the demolding process and causing damage. After moving to a safe position, the fingers of both hands are respectively buckled into the adjacent drive grooves 23 and pulled toward the top of the limit frame 11. At this time, the demolding sleeve 15 moves and drives the demolding plate 14 to move, and the demolding is completed. The movement of the plate 14 drives the extrusion rod 13 to slide inside the limit frame 11. Since the groove at the bottom of the limit frame 11 is arranged in an arc shape, the extrusion rod 13 gradually approaches the building platform 9 during the upward movement. The extrusion rod 13 gradually approaches the building platform 9, and the two ends of the bending plate 12 also approach the building platform 9. When the two ends of the bending plate 12 gradually approach the building platform 9, the middle part of the bending plate 12 bulges and drives the aluminum plate 10 to deform. It is worth mentioning that deformation reserved parts are left on both sides of the aluminum plate 10, so that the aluminum plate 10 itself will not generate tension during the bulging process, thereby effectively preventing the tension from being transmitted to the source applicator and causing damage to the source applicator.

[0038] More specifically, through the above-mentioned structure, different strengths of demolding tension can be selected according to the tensile strength of different materials to avoid damage to the applicator due to excessive tension during demolding, and the tension on which side can be appropriately increased can be selected according to the printing specific gravity of the applicator to avoid demolding damage to the applicator while reducing the difficulty of demolding. Specifically, when it is necessary to control the demolding tension, the extrusion knobs 21 on the two demolding sleeves 15 are rotated respectively. The rotation of the extrusion knobs 21 drives the extrusion plate 20 thereon to slide inside the demolding sleeve 15. The sliding of the demolding sleeve 15 drives the extrusion spring 19 to stretch or contract, thereby changing the abutment force between the block 18 and the slot 17. When demolding, if the adhesion force of the applicator on the aluminum plate 10 is greater than the tension that the applicator can withstand, the demolding sleeve 15 is continued to be pulled, the extrusion spring 19 is extended, and the block 18 slides outside the slot 17, thereby protecting the applicator from excessive force.

[0039] The cleaning mechanism 5 is used to clean the impurities of the biocompatible resin in the resin tank 6 to improve the printing quality. The cleaning mechanism 5 includes an upper cleaning shell 26 slidably connected to the top of the resin tank 6, an upper cleaning cotton 29 is rotatably connected inside the upper cleaning shell 26, and a CMOS sensor 25 is movably connected to one side of the resin tank 6;

[0040] The cleaning mechanism 5 also includes a driving shell 27 magnetically attracted to one side of the upper cleaning shell 26, a rotating motor is fixedly installed inside the driving shell 27, the output end of the rotating motor is fixedly connected to the driving slot 23, one end of the driving slot 23 is plum blossom-shaped, the upper cleaning shell 26 is rotatably connected to the inside of the through pipe 30, one side of the through pipe 30 is provided with a transmission slot 31, the transmission slot 31 is adapted to one end of the transmission rod 32, and the upper cleaning cotton 29 is slidably sleeved on the outside of the through pipe 30;

[0041] A liquid suction chamber 36 is movably connected to one side of the upper cleaning shell 26 . The input end of the liquid suction chamber 36 is connected to one end of the through pipe 30 . The through pipe 30 is connected to the outside of the upper cleaning shell 26 through the upper cleaning cotton 29 .

[0042] By setting the above structure, impurities inside the resin tank 6 can be cleaned to improve the printing effect. Specifically, during the printing process of the printer 3, there may be residues such as solidified resin, failed prints, debris, and precipitated pigments inside the resin tank 6. These residues may affect new printing jobs and the refraction of ultraviolet lasers, resulting in printing failures or degradation of component performance. During the printing process, the ultraviolet laser is mainly irradiated on the biocompatible resin to solidify it. When the ultraviolet laser is partially blocked or astigmatism occurs during the refraction process, it will cause the printing source to deviate.

[0043] More specifically, during the printing process of the printer 3, the CMOS sensor 25 can be connected to one side of the resin tank 6 to monitor the setting of the ultraviolet laser in real time. The CMOS sensor 25 is a prior art and is a high-sensitivity linear array image sensor. The sensor has high sensitivity and high tolerance to ultraviolet light in the ultraviolet region and can detect ultraviolet lasers of specific wavelengths through biocompatible resins. When the CMOS sensor 25 detects that the ultraviolet laser has scattered light or polarized light, printing is stopped at this time, and the building platform 9 is lifted, and the through tube 30 is inserted into the upper cleaning shell 26, and then the washed upper cleaning cotton 29 is slidably sleeved on the outside of the through tube 30, and the rubber pad 33 is sleeved on one end of the through tube 30, and then the liquid suction chamber 36 is installed inside the liquid suction chamber 36 so that its input end is connected to one end of the through tube 30, and then The upper cleaning shell 26 is placed on one side of the top of the resin tank 6, and then a rubber pad 33 is sleeved on the outside of the transmission rod 32. At this time, the drive shell 27 is magnetically adsorbed on one end of the upper cleaning shell 26. During the adsorption process, the transmission rod 32 is adapted to the transmission slot 31. At this time, the rotating motor is started, and the output end of the rotating motor drives the rubber pad 33 to rotate. The rotation of the rubber pad 33 drives the through pipe 30 to rotate. The rotation of the through pipe 30 drives the upper cleaning cotton 29 to rotate, and drives the two rubber pads 33 to roll on the top of the resin tank 6, and at the same time drives the upper cleaning shell 26 to move on the top of the resin tank 6. During the movement, impurities on the top of the biocompatible resin in the resin tank 6 will be rolled into the upper cleaning shell 26 by the upper cleaning cotton 29, and collected in the liquid suction chamber 36 through the through pipe 30. After cleaning, they are disassembled and cleaned in turn for the next use.

[0044] The bottom of the upper cleaning shell 26 is slidably connected to the lower cleaning shell 28, and the lower cleaning cotton 34 is rotatably connected inside the lower cleaning shell 28. The outer part of the lower cleaning cotton 34 abuts against the bottom of the resin tank 6. The lower cleaning shell 28 is rotatably connected to the cleaning rotating rod 35, and the lower cleaning cotton 34 is slidably sleeved on the outer part of the cleaning rotating rod 35. The lower cleaning shell 28 is rotatably connected to the upper gear 37, and the inner part of the upper gear 37 is slidably engaged with the outer part of the through pipe 30. The inner part of the lower cleaning shell 28 is also rotatably connected to the lower gear 38, and the upper gear 37 is meshed with the lower gear 38. The lower gear 38 and the outer part of the cleaning rotating rod 35 are rotatably sleeved with the same transmission belt 39, and the outer part of the transmission rod 32 and the outer part of the through pipe 30 are movably sleeved with rubber pads 33.

[0045] Further, in the above scheme, by setting the above structure, impurities at the bottom of the biocompatible resin inside the resin tank 6 can be cleaned. Specifically, when the CMOS sensor 25 detects that the refraction of the ultraviolet laser is inaccurate, it is possible that the impurities at the bottom of the biocompatible resin affect the refraction of the ultraviolet laser. At this time, the drive shell 27 is separated from the upper cleaning shell 26, and the cleaned lower cleaning cotton 34 is slidably sleeved on the outside of the cleaning rotating rod 35, and the lower cleaning shell 28 is slidably installed inside the upper cleaning shell 26. At this time, the outside of the through pipe 30 is clamped with the inside of the upper gear 37, and the drive shell 27 is reinstalled for use;

[0046] Start the rotating motor, and the output end of the rotating motor drives the transmission rod 32 to rotate, the transmission rod 32 drives the through pipe 30 to rotate, the through pipe 30 drives the upper gear 37 to rotate, the upper gear 37 drives the lower gear 38 to rotate, the lower gear 38 rotates and drives the cleaning rotating rod 35 to rotate through the liquid suction chamber 36, the cleaning rotating rod 35 drives the lower cleaning cotton 34 to rotate, and the bottom of the resin tank 6 is cleaned. After the cleaning is completed, the lower cleaning cotton 34 is disassembled and cleaned for the next use.

[0047] Working principle of the present invention: When in use, when the CMOS sensor 25 detects that the ultraviolet laser has astigmatism or polarization, printing is stopped at this time, and the building platform 9 is lifted, the through tube 30 is inserted into the upper cleaning shell 26, and then the washed upper cleaning cotton 29 is slidably sleeved on the outside of the through tube 30, and the rubber pad 33 is sleeved on one end of the through tube 30, and then the liquid suction chamber 36 is installed inside the liquid suction chamber 36 so that its input end is connected with one end of the through tube 30, and then the upper cleaning shell 26 is placed on the top side of the resin tank 6, and then a rubber pad 33 is sleeved on the outside of the transmission rod 32, and the drive shell 27 is magnetically adsorbed on one end of the upper cleaning shell 26 During the adsorption process, the transmission rod 32 is matched with the transmission groove 31, and the rotating motor is started at this time. The output end of the rotating motor drives the rubber pad 33 to rotate, and the rotation of the rubber pad 33 drives the through pipe 30 to rotate. The rotation of the through pipe 30 drives the upper cleaning cotton 29 to rotate, and drives the two rubber pads 33 to roll on the top of the resin tank 6, and drives the upper cleaning shell 26 to move on the top of the resin tank 6. During the movement, the impurities on the top of the biocompatible resin in the resin tank 6 will be rolled into the upper cleaning shell 26 by the upper cleaning cotton 29, and collected in the liquid suction chamber 36 through the through pipe 30. After the cleaning is completed, they are disassembled and cleaned in turn for the next use;

[0048] When the CMOS sensor 25 detects that the UV laser refraction is inaccurate, it may be that the impurities at the bottom of the biocompatible resin affect the refraction of the UV laser. At this time, the drive shell 27 is separated from the upper cleaning shell 26, the cleaned lower cleaning cotton 34 is slidably sleeved on the outside of the cleaning rotating rod 35, and the lower cleaning shell 28 is slidably installed inside the upper cleaning shell 26. At this time, the outside of the through pipe 30 is clamped with the inside of the upper gear 37, and the drive shell 27 is reinstalled for use;

[0049] The rotating motor is started, and the output end of the rotating motor drives the transmission rod 32 to rotate, the transmission rod 32 drives the through pipe 30 to rotate, the through pipe 30 drives the upper gear 37 to rotate, the upper gear 37 drives the lower gear 38 to rotate, the lower gear 38 rotates and drives the cleaning rotating rod 35 to rotate through the liquid suction chamber 36, the cleaning rotating rod 35 drives the lower cleaning cotton 34 to rotate, and the bottom of the resin tank 6 is cleaned. After the cleaning is completed, the lower cleaning cotton 34 is disassembled and cleaned, and it can be used next time;

[0050] After the source applicator is printed using the printer 3, the source applicator is now adhered to the bottom of the aluminum plate 10. At this time, the printer 3 is opened, and both hands hold the limit frames 11 on both sides of the building platform 9, and the building platform 9 is separated from the lifting platform 7. At this time, the building platform 9 is moved to a safe position for demoulding to prevent the source applicator from falling and bumping during the demoulding process. When it is moved to a safe position, the fingers of both hands are respectively buckled into the inside of the adjacent driving grooves 23 and pulled toward the top of the limit frame 11. At this time, the demoulding sleeve 15 moves and drives the demoulding plate 14 to move, and the movement of the demoulding plate 14 drives the extrusion rod 13 on the limit frame 1 1, since the groove at the bottom of the limit frame 11 is arranged in an arc shape, the extrusion rod 13 gradually approaches the building platform 9 during the upward movement, and the extrusion rod 13 gradually approaches the building platform 9, and the two ends of the bending plate 12 also approach the building platform 9. When the two ends of the bending plate 12 gradually approach the building platform 9, the middle part of the bending plate 12 bulges and drives the aluminum plate 10 to deform. It is worth mentioning that deformation reserved parts are left on both sides of the aluminum plate 10, so that the aluminum plate 10 itself will not generate tension during the bulging process, thereby effectively preventing the tension from being transmitted to the source applicator and causing damage to the source applicator.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
