Application status and prospect of 3d medical visualization technologyin precision surgery of liver tumor
医学三维可视化技术在肝肿瘤精准手术中的应用现状及展望

摘要

肝肿瘤属于常见的肝部疾病，该病发病率高，死亡率也居高不下，从全球来看，我国肝脏肿瘤的发生率以及死亡率均要高于发达国家，针对该病在治疗上以手术切除为主要的治疗方式，以利于患者可以得到更久的生存期。传统的解剖型肝部切除术相对在根治的效率上明显提升，但也因为肝内部的结构复杂，变异性大，增加了手术的风险，导致并发症增加。而精准理念的深入发展，该种手术方式明显降低了传统肝切除术的风险。该种手术方式确定性更高，同时具有可控性和预见性，可以在去除病灶上保证最大化，而同时也很好的保护了肝脏结构的完整性，可最大化控制了手术的出血机率，避免了全身性的创伤，提高了患者术后康复率。该种手术方式需要结合当今发达的科技，通过CT以及MRI技术的协助，提供患者肝脏部位的影像，并结合3DV技术来建立人体肝脏的三维模式，该种方式在操作上处理速度更快速，较高的自动化程序，操作上更为简单，可以清晰了解患者肝脏脉管的走形以及肿瘤情况，更好的确定肝切除的平面。同时计算好患者肝部残余的体积，明确患者术后恢复生活质量情况，提高了患者手术的安全性，减少了手术带来的创伤。

Abstract

Liver tumors, belongs to the common liver disease, the disease incidence rate high, mortality is high, from a global perspective, our country the morbidity and mortality of liver cancer are higher than in the developed countries, for the disease in the treatment of surgical resection is the main way of treatment, to facilitate the survival of patients can get longer, Compared with traditional anatomic hepatectomy, the efficiency of radical resection is significantly improved. However, due to the complex internal structure of the liver and great variability, the risk of surgery is increased, leading to increased complications. With the in-depth development of precision concept, this surgical method significantly reduces the risk of traditional hepatectomy. This surgical method has higher certainty, controllability and predictability, which can maximize the removal of lesions, protect the integrity of liver structure, control the bleeding rate of surgery, avoid systemic trauma, and improve the postoperative recovery rate of patients. This surgical method needs to be combined with today's advanced technology. With the assistance of CT and MRI technology, the image of the patient's liver is provided, and 3DV technology is used to establish a THREE-DIMENSIONAL model of the human liver. This method has faster processing speed, higher degree of automation, and simpler operation. It can well understand the shape of the patient's liver vessels and the tumor situation, can better determine the plane of liver resection, and calculate the residual volume of the patient's liver, to clarify the quality of life of the patient after surgery. It improves the safety of surgery and reduces the trauma caused by surgery.
