Medical photosensitive resin jet multicolor 3D printer

Abstract

The invention discloses a medical photosensitive resin jet multicolor 3D printer. The printer comprises a sectional material framework, a forming platform, a peristaltic pump, a resin storage box anda printing head, wherein a lifting mechanism is connected to the center of the interior of the sectional material framework, the resin storage box is arranged on a fixing frame of the top of the sectional material framework, the peristaltic pump is fixed below the resin storage box, second guide rails are fixed at the two ends of the top of the sectional material framework, sliding seats are arranged on the second guide rails in a sliding manner, first guide rails are inserted between the sliding seats, a sliding block is connected between the first guide rails, and the printing head is arranged at the bottom of the sliding block. According to the printer, the sectional material frame, the forming platform, the peristaltic pump, the resin storage box and the printing head are arranged, sothat the rapid forming can be carried out on the printed liquid photosensitive resin effectively, a body tissue structure can be effectively distinguished through different colors of the resin, the doctor can quickly recognize the body tissue data of a patient and judge the lesion of the patient, the misjudgment and the misdiagnosis of diseases are reduced, the operative planning is facilitated, and the operative risk is reduced.

Description

technical field [0001] The invention relates to the field of medical printers, in particular to a medical photosensitive resin jetting multi-color 3D printer. Background technique [0002] At present, in the medical industry, people often use CT data and MRI data to understand the patient's condition, but because the data are only plane reference values, it is impossible for doctors to intuitively feel and understand the situation between the various tissues of the patient's lesion location, so The method of establishing a three-dimensional model of a patient's body tissue through CT data and MRI data has been gradually used in hospitals for doctors to diagnose illnesses, plan preoperative plans, and evaluate treatment plans to reduce misdiagnosis and misdiagnosis of diseases. [0003] The photosensitive resin jet 3D printer is the most common existing model building machine, but there are some problems in the use of this equipment, and it cannot be put into use in the medic...

[0002] At present, in the medical industry, people often use CT data and MRI data to understand the patient's condition, but because the data are only plane reference values, it is impossible for doctors to intuitively feel and understand the situation between the various tissues of the patient's lesion location, so The method of establishing a three-dimensional model of a patient's body tissue through CT data and MRI data has been gradually used in hospitals for doctors to diagnose illnesses, plan preoperative plans, and evaluate treatment plans to reduce misdiagnosis and misdiagnosis of diseases

[0003] The photosensitive resin jet 3D printer is the most common existing model building machine, but there are some problems in the use of this equipment, and it cannot be put into use in the medical neighborhood. It is disclosed in the patent application publication number CN 108099182 A A 3D printing process of photosensitive resin is proposed, which includes the following steps: firstly, the program is used to slice the digital model, and the scanning path is designed to precisely control the movement of the laser scanner and the lifting table; then, the laser beam is controlled by the numerical control device The scanner irradiates the surface of the liquid photosensitive resin according to the designed scanning path, and solidifies a specific area of ​​the liquid photosensitive resin to form a cross-section of the model; then controls the lifting table to descend a small distance, so that the cured layer is covered with a new layer Liquid resin, and scan the second layer at the same time, at this time, the second cured layer will be firmly bonded to the previous cured layer, this step is repeated, and the object is generated layer by layer from the bottom

But it has the following disadvantages: by irradiating the surface of the liquid photosensitive resin with the laser beam, the light needs to be refracted before it can be irradiated on the liquid surface, and the liquid photosensitive resin cannot be quickly cured, and the dripping liquid photosensitive resin is easy to spread on the lifting platform, thereby It affects the shape and accuracy of the pattern, and the process does not indicate that different colors can be continuously printed according to the color of the pattern, so it cannot be well applied to the medical neighborhood, and it cannot be printed according to the characteristics of different body tissues according to the patient. The applicability is not good good
