Abstract

The invention discloses a manufacturing method for an artificial skull repair prosthesis by the adoption of the 3D printing technology. The method is used for manufacturing the artificial skull repair prosthesis which is attractive in appearance, good in anastomosis and few in complication for skull-defect patients. The manufacturing method for the artificial skull repair prosthesis has the advantages that according to the manufacturing method, the skull is manually manufactured by the adoption of the 3D printing technology to repair and rebuild the skull of a patient, so that the defects, in molding, strength, process, anastomosis and the like, of common skull repair materials are overcome, the manufacturing cycle is greatly shortened, and the side effects of clinical application are remarkably reduced.

Description

一种人工颅骨修复假体制备方法 An artificial skull prosthesis system backup method

技术领域 FIELD

[0001] 本发明涉及一种人工颅骨修复假体制备方法,尤其涉及3D打印颅骨缺损塑形重建假体的制作。 [0001] The present invention relates to a preparation method of an artificial skull prosthesis system, particularly to a print making 3D shaped skull defect reconstruction prosthesis.

背景技术 Background technique

[0002] 由于战争、车祸、重物打击等各种原因导致许多患者因为手术或者颅骨损伤等原因导致颅骨缺损,部分患者病情平稳后,颅骨缺损影响美容,并且缺损部位没有颅骨的保护存在,存在安全隐患,随着生活水平的提高,不仅从安全角度,从生活质量角度,许多患者要求颅骨缺损的修复。 [0002] For various reasons the war, car accidents, heavy blow as a result of many patients because of surgery or injury as a result of skull skull defects after the smooth part of the patient's condition, skull defects affect the beauty and unprotected skull defect exists, there is security risks, with the improvement of living standards, not only from a security perspective, from the perspective of quality of life, many patients required to repair skull defects. 为了美容、脑部安全等目的,伴随而来的就是颅骨修补。 For beauty, brain and other security purposes, it is accompanied by skull repair. 因此,就该研究成果的应用上,存在着巨大的潜在用户,市场应用前景广阔。 Therefore, in relation to the application of research results, there is a huge potential users, the market prospect is broad.

[0003] 在制造工艺上,国内外主要有四种方法:手工塑形、铸造、模具压制和多点成形技术。 [0003] In the manufacturing process, there are mainly four methods: manual shaping, casting, die pressing, and multi-point forming technology. 现在医学上常用钛网制作颅骨修复假体,钛网虽然具有组织相容性好的特点,但强度和硬度均低于颅骨组织,耐冲击时产生塑性变形。 Now making titanium mesh commonly used medicine cranial prosthesis, although titanium mesh having a tissue compatibility and good, but strength and hardness are lower than the skull tissue, plastic deformation when impact resistance. 钛网边缘锋利容易刺破皮肤而暴露出来,弓丨起皮肤感染。 Titanium mesh easily pierce the skin and sharp edges exposed, bow Shu from skin infections. 而且金属物质的存在,存在心理障碍,并且影响进一步的MRI等影像学检查(MRI存在磁性,对于缺损金属重建材料存在弊端),这些缺点都是钛网颅骨修复难以克服的缺点,严重影响了修复效果。 And the presence of metal species, the presence of psychological disorders, and the like affect the further MRI imaging (MRI magnetic presence, disadvantages exist for the reconstruction of defects in metallic materials), these drawbacks are titanium mesh cranial prosthesis difficult to overcome, severely affect the repair effect. 铸造和模具压制在修复假体质量上有所提高,但制造周期长、成本高柔性差,以目前的制备手段很难保证一次手术完成清创和修补。 Casting mold and pressed onto the prosthetic quality has improved, but the manufacturing cycle, high cost of poor flexibility, the current methods for preparing an operation is difficult to ensure complete debridement and repair. 而压痕、起皱、回弹和边缘翘曲是多点成形中特有的成形缺陷,压痕和起皱影响颅骨修复体的外形美观,回弹会使修复体尺寸与骨窗尺寸不吻合,导致修复体塌陷或固定松动。 The indentation, wrinkle, springback and edge lifting is unique to multi-point forming shaped defects, creasing and wrinkling affect appearance cranial prosthesis, the prosthesis will rebound bone size window size does not match, lead to collapse or prosthesis loosening. 边缘翘曲会使使修复体与骨窗不能良好贴合,影响修复质量。 Edge lifting will make the prosthesis and bone window can not be a good fit, affect the repair quality. 颅骨修复技术,不仅关系到广大颅骨缺损患者健康和美观,而且严重影响患者今后的生活质量,因此对颅骨修复体制备技术的研究具有重要的意义。 Skull repair technology, not only to the majority of patients with skull defects healthy and beautiful, but also seriously affect the quality of life of patients in the future, so it has great significance for the study of repair of skull preparation techniques.
