我国消化内镜技术近年来发展迅速,但内镜医师培训发展相对缓慢,未形成与人民诊疗需求相适应的内镜医师培训体系。美国、日本和英国等发达国家均形成了相对完善的内镜医师培训体系,对我国内镜医师培训工作具有重要借鉴意义。学习国际先进理念,结合我国实际国情,实现内镜医师培训统一报名准入、管理部署、课程学习、考核认证、监督质控,系统性地培养一大批合格、优秀的消化内镜医师,是提升我国新时代消化内镜诊疗水平的必由之路。本文就内镜医师成长轨迹,合格、优秀内镜医师应具备的能力素质和国内外消化内镜医师培训进展作一述评。 相似文献

消化性溃疡并发症有出血、穿孔、胃输出端梗阻,过去这些并发症常常进行手术治疗,随着治疗内镜的发展,许多并发症病人不需手术即可治愈。1 出血当溃疡基底部动脉受到侵蚀就会发生出血,溃疡出血是最常见的上消化道出血原因,直到不久前仍认为确切的止血措施为外科手术。自从纤维内镜的发展,人们对内镜下止血越来越感兴趣,建立了许多有效的内镜下溃疡止血方法,并对一些方法进行了随机临床对照研究。 相似文献

目的探讨内镜超声检查术(EUS)对消化道黏膜下肿瘤(SMT)层次来源与性质的诊断能力及局限性。方法2016年1月至2018年12月,收治于上海交通大学医学院附属瑞金医院消化科,术前EUS诊断为消化道SMT,接受内镜下切除术治疗,术后病理资料完整的211例病例纳入回顾性研究,以手术病理为参照,分析术前EUS诊断SMT的准确率以及EUS对SMT的诊断局限性。结果病灶位于食管66例、胃108例、十二指肠2例、直肠35例。EUS对病变层次来源的诊断准确率达99.5%(210/211)。就病变性质而言,160例EUS诊断准确(75.8%,160/211)。就不同部位的病变而言,EUS对食管黏膜-黏膜下层来源、食管固有肌层来源、胃黏膜-黏膜下层来源、胃固有肌层来源、十二指肠黏膜下层来源、直肠黏膜-黏膜下层来源病变的诊断准确率分别为90.0%(54/60)、83.3%(5/6)、31.0%(13/42)、89.4%(59/66)、50.0%(1/2)、82.9%(29/35)。对于EUS显示为低回声为主的病变,平滑肌瘤、平滑肌瘤/胃肠间质瘤、神经内分泌肿瘤分别是食管黏膜来源、消化道固有肌层来源和直肠黏膜-黏膜下层来源病变的较常见肿瘤类型。结论尽管EUS对消化道SMT的诊断具有不可替代的重要作用,但其对胃黏膜-黏膜下层来源的各类病变缺乏特异的鉴别手段。由于其中部分病变可能存在恶性潜能,因此在作出诊断时需要更加谨慎。 相似文献

Pier Paolo Valentini 《International Journal on Interactive Design and Manufacturing》2009,3(2):109-119
In this paper, a computer-aided methodology based on augmented reality to manipulate and interactively assemble virtual objects
is presented. The developed system, based on both hardware and software implementation, allows the user to be immersed in
an augmented scene (real world and virtual objects) by means of an head-mounted display and interact with the virtual components
using a glove with sensors. The author presents the implementation of the system facing the problems concerning the interpretation
of user’s intent to grasp and move the objects and the computer-aided assembly based on a novel approach concerning active
features dynamic recognition. An example of implementation is herein reported and discussed. 相似文献

Recent advancements in virtual reality graphics and models have allowed virtual reality simulators to be incorporated into a variety of endoscopic training programmes. Use of virtual reality simulators in training programmes is thought to improve skill acquisition amongst trainees which is reflected in improved patient comfort and safety. Several studies have already been carried out to ascertain the impact that usage of virtual reality simulators may have upon trainee learning curves and how this may translate to patient comfort. This article reviews the available literature in this area of medical education which is particularly relevant to all parties involved in endoscopy training and curriculum development. Assessment of the available evidence for an optimal exposure time with virtual reality simula-tors and the long-term benefits of their use are also discussed. 相似文献

The OSCE is a reliable evaluation method to estimate the preclinical examination of dental students. The most ideal assessment for OSCE is used the augmented reality simulator to evaluate. This literature review investigated a recently developed in virtual reality (VR) and augmented reality (AR) starting of the dental history to the progress of the dental skill. As result of the lacking of technology, it needs to depend on other device increasing the success rate and decreasing the risk of the surgery. The development of tracking unit changed the surgical and educational way. Clinical surgery is based on mature education. VR and AR simultaneously affected the skill of the training lesson and navigation system. Widely, the VR and AR not only applied in the dental training lesson and surgery, but also improved all field in our life. 相似文献

The use of simulators as educational tools for medical procedures is spreading rapidly and many efforts have been made for their implementation in gastrointestinal endoscopy training. Endoscopy simulation training has been suggested for ascertaining patient safety while positively influencing the trainees' learning curve. Virtual simulators are the most promising tool among all available types of simulators. These integrated modalities offer a human-like endoscopy experience by combining virtual images of the gastrointestinal tract and haptic realism with using a customized endoscope. From their first steps in the 1980s until today, research involving virtual endoscopic simulators can be divided in two categories: investigation of the impact of virtual simulator training in acquiring endoscopy skills and measuring competence. Emphasis should also be given to the financial impact of their implementation in endoscopy, including the cost of these state-of-theart simulators and the potential economic benefits from their usage. Advances in technology will contribute to the upgrade of existing models and the development of new ones; while further research should be carried out to discover new fields of application. 相似文献

Virtual reality (VR), even if it does not represent any more a novel technology, is one of the most powerful tool to help
designers during the development of new projects. This is proved by very numerous research activities related to this field.
In this research, we have studied a new way to approach the development of a product. We present the ongoing development of
a system, called VirDe, acronym of virtual design, which can allow the designers to perform the whole design process, from the modelling phase to
the finite element method (FEM) simulation analysis, in a virtual reality environment. This new method allows remarkable time
and money saving in the overall product design process, but the most important contribution of VirDe is that, as far as we concerned, there is no known similar approach which has been studying the simultaneous combination
of CAD, FEM and virtual environment (VE). 相似文献
