英國外科醫生用3D打印修復患者面容

Surgeons in Swansea are using 3D printing technology to rebuild a patient's face which was crushed in a motorbike accident.

It works by using images from a CT scan to design implants that are created in titanium by a 3D printer.

The groundbreaking work is being led by Morriston Hospital consultant maxillofacial surgeon Adrian Sugar.

It is being featured in an exhibition at the Science Museum in London before the operation itself is carried out.

There have been cases using custom-made titanium implants to correct congenital conditions, those which arise at birth or shortly after.

However, this is thought to be one of the first such reconstructions following an injury.

Abertawe Bro Morgannwg University Health Board's maxillofacial laboratory services manager and reconstructive scientist Peter Evans said: "The patient suffered trauma and had multiple injuries across his body, including some quite severe facial injuries.

"He underwent emergency Surgery at the time and we are now at the stage where we can do a proper reconstruction of his face."

The project is the work of the Centre of Applied Reconstructive Technologies in Surgery (Cartis).

The centre was established in 2006 as a partnership between Morriston Hospital's maxillofacial unit and Product Design and Research (PDR) based at Cardiff Metropolitan University.

Cartis aims to make Wales a world leader in the research, development and application of advanced medical technologies in surgery.

Mr Sugar and Mr Evans worked with PDR's Sean Peel and Ffion O'Malley to plan the complex surgery, which will involve repositioning the patient's facial bones.

They worked from a CT scan that allowed them to create a mirror image of the unaffected side of the patient's face.

From this they designed guides to cut and position the bones with pinpoint accuracy, as well as implants tailor-made for the patient.

The guides and implants are being produced from medical-grade titanium in Belgium.

Mr Evans added: "We have done everything up the point of surgery. The concept of the operation has been virtually designed and we hope to do the work very soon.

"The patient's facial symmetry will be restored so he should be back to normal as far as his facial looks are concerned."英國斯旺西的外科醫生正在用3D打印技術來修復一個病人的臉部，該患者的臉在一次摩托車事故中受創。

他們利用CT掃描的影像來設計移植物，該移植物是通過3D打印機用鈦合金打印的。

此項開創性的工作是由莫里斯頓醫院頜面外科醫生艾德里安·休格領導的。

在進行手術之前，它在倫敦科學博物館的一個展覽會上亮相了。

已經有案例將定製的鈦合金移植物應用於矯正出生時或出生後不久形成的先天性不足。

但是，此次手術被認爲受傷後修復手術的先例。

Abertawe Bro Morgannwg大學健康委員會頜面實驗服務經理、修復專家彼得•埃文斯說：“患者遭受創傷，全身多處受傷，面部也嚴重受傷。”

“當時我們給他做了急診手術，現在我們正在盡力給他做一個面部修復手術”。

該項目是外科應用重建技術中心（Cartis）的傑作。

該中心成立於2006年，是莫里斯頓頜面部門和位於卡迪夫城市大學的產品設計和研究所（FDR）合作設立的。

Cartis旨在使威爾士在外科手術中先進醫療技術的研究，開發和應用處於世界領先地位。

休格和埃文斯與PDR的兩位工作人員一起合作策劃了此項複雜的手術，其中包括重排患者的面骨。

CT掃描讓他們創建了病人臉部未受傷的那部分的鏡像。
