    目的了解厦门市居民2004-2009年恶性肿瘤死亡的原因和分布特征,为恶性肿瘤的防治工作提供依据。方法应用死亡率、标化死亡率、潜在减寿年数(PYLL)及潜在减寿率(PYLL率)等指标分析居民恶性肿瘤死亡情况。结果恶性肿瘤年平均死亡率为148.07/10万,PYLL率为21.68‰,均居全死因的首位。在恶性肿瘤中,肝癌死亡率35.24/10万,居第1位,其次是肺癌、食管癌、胃癌、肠癌。1~14岁儿童、中青年、老年组的首位恶性肿瘤死因分别是白血病、肝癌、肺癌,恶性肿瘤的平均PYLL为0.13人年/人,全人群主要恶性肿瘤按PYLL率排序,依次为肝癌(0.590%)、肺癌(0.346%)、食管癌(0.334%)、胃癌(0.226%)、肠癌(0.129%)。结论恶性肿瘤是导致居民死亡的首要死因,应根据不同人群、不同肿瘤的特点,采取综合性干预措施,加强环境保护,改变不良的生活习惯,对降低居民恶性肿瘤死亡率有十分重要的意义

    以上消化道介入为例,在前期研制的YunSRobot内镜机器人平台上开展软式内镜自主介入策略研究.基于Faster-RCNN算法和数学形态学图像处理方法从镜下图像中提取消化道解剖特征,并设计自主化镜体操控和弯曲定向策略实现内镜在上消化道中的自主介入.在高仿真度的上消化道模型中开展了对照实验,结果表明本文方法的介入成功率为100%.与非专业人员主从介入相比,平均耗时从262.01 s降低到197 s,介入力的最大值从11.8 N降到9.6 N.与专业人员主从介入相比,介入力最大值基本一致,仅多耗时34.33 s.本文提出的自主化介入策略可以拓展到呼吸道、尿道等其他腔道的软式内镜介入.</p

    Design of coaxial intervention catheter robot for Endoscopic Retrograde Cholangio-Pancreatography

    Due to the high incidence of biliary and pancreatic diseases, ERCP (Endoscopic Retrograde Cholangio-Pancreatography) is widely used as an effective method for treating biliary and pancreatic diseases. However, the location of biliary and pancreatic diseases is special, and the currently used ERCP surgical instruments are not flexible enough to make the intubation process difficult and cause damage to human tissues. This paper presents a new type of coaxial catheter intervention robot, which is composed of a flexible mechanical arm, a driving mechanism, and a guide wire conveying mechanism. The robot is coaxially transported to the nipple through the duodenoscope, which can provide the doctor with a clear surgical field of vision. The 2-degree-of-freedom flexible manipulator can bend in four directions, so that the direction of the catheter is as consistent as possible with the axis of the cholangiopancreatic duct, thus simplifying insertion Tube process. After the prototype was manufactured, the biliary and pancreatic duct model intervention experiment was carried out. The experiment verified the feasibility of the flexible robot system. The experimental results showed that compared with manual intubation, the efficiency is higher and the operation difficulty is lower
