Manufacturing method for manufacturing skull repairing material by utilizing three-dimensional (3D) printing technology

Abstract

The invention discloses a manufacturing method for manufacturing a skull repairing material by utilizing a three-dimensional (3D) printing technology. The manufacturing method for manufacturing the skull repairing material by utilizing the 3D printing technology comprises the following steps of before use, firstly acquiring patient skull CT image data; modeling and repairing data through professional software in a computer; copying into a 3D printer after processing; emitting an ultraviolet light to a glass window through an exposure module according to setting data; during the irradiating process, enabling a lifting mechanism to slowly and upwards slide so as to drive a base plate to move; during the base plate moving process, solidifying a rein in a resin groove irradiated by the ultraviolet light on the bottom part of the base plate, and enabling a resin which is not irradiated by the ultraviolet light to keep at a liquid state; after printing, taking out a printed skull model, manually cleaning, polishing, and carrying out postprocessing; after processing, cleaning, sterilizing and packaging the printed skull model; and after manually cleaning, polishing, and carrying out postprocessing on the printed skull model, placing in a sterile space, and curing for 20 to 30min.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a method for making skull repair materials using 3D printing technology. Background technique [0002] When traumatic brain injury or cerebral hemorrhage causes intracranial hypertension, decompressive craniectomy is currently used both at home and abroad. The purpose is to allow the swollen brain tissue to expand and release pressure, and the removed skull can also release a certain amount of space, thereby The purpose of decompression was achieved, but a "skull defect" was artificially created. [0003] In the traffic accidents in my country in the past 10 years, craniocerebral injury occupies the second place among all kinds of trauma, and its incidence rate is 22-42%. There are about 600,000 person-times every year, and more than 100,000 people die. Cerebrovascular diseases The rate is 868.7 per 100,000 population, and the mortality rate in the acute stage is 5...

[0002] When intracranial hypertension occurs due to traumatic brain injury or cerebral hemorrhage, decompressive craniectomy is currently used both at home and abroad. The purpose is to allow the swollen brain tissue to expand and release pressure, and the removed skull can also release a certain amount of space, thereby Achieved the purpose of decompression, but artificially created a "skull defect"

[0003] In the traffic accidents in my country in the past 10 years, craniocerebral injury occupies the second place among all kinds of trauma, and its incidence rate is 22-42%. There are about 600,000 person-times every year, and more than 100,000 people die. Cerebrovascular diseases The rate is 868.7 per 100,000 population, and the mortality rate in the acute stage is 50%. At present, titanium mesh is generally used as a repair material for skull defects (two-dimensional design, three-dimensional processing, computer modeling, etc.), titanium metal has poor biocompatibility and many disadvantages , now the best cranial repair material is PEEK material, but the price is expensive

[0004] After decompressive craniectomy, cranioplasty is often required 3-6 months later (requiring a second cranioplasty), which is more traumatic and expensive for reoperation
