目的探讨超声刀在腔镜手术中的使用方法及其临床应用价值.方法收集并分析采用超声刀在腔镜下完成的各类外科手术448例的临床资料.结果全组病人没有因为使用超声手术刀止血不彻底而导致手术中转开腹及术后出血,也没有因为使用超声手术刀而导致的脏器损伤及空腔脏器延迟性穿孔等并发症的出现.结论尽管所有型号的超声刀目前仍存在一些技术上的缺陷,但其无烟、操作简便安全、切割止血可靠等优点使原来许多传统开放的复杂手术在腔镜下施行成为现实.由于腹腔镜及其器械均呈长杆形,对于深部小血管的离断及组织分离优于开放手术,是现代腔镜外科必不可少的设备. 相似文献

机器人手术系统用于早期肺癌治疗是近10年发展起来的一项新的微创治疗技术。与传统的电视胸腔镜( vide-o-assisted thoracoscopic surgery,VATS)比较,除具有VATS微创的基本优点外,其3D高清成像,高倍数放大,符合人体工程学的仿真机械臂及多自由度转腕功能( Endowrist)等,通过人机交流还原了开放式手术中术者眼与器械、手与器械的同步运动,将微创外科技术提高到了一个新的境界。本文就机器人手术系统在早期肺癌治疗中的应用现状做一简述。 相似文献

Object To investigate the usefulness of a newly developed magnetic resonance (MR) image-guided surgical robotic system for minimally
invasive laparoscopic surgery.
Materials and methods The system consists of MR image guidance [interactive scan control (ISC) imaging, three-dimensional (3-D) navigation, and
preoperative planning], an MR-compatible operating table, and an MR-compatible master–slave surgical manipulator that can
enter the MR gantry. Using this system, we performed in vivo experiments with MR image-guided laparoscopic puncture on three
pigs. We used a mimic tumor made of agarose gel and with a diameter of approximately 2 cm.
Results All procedures were successfully performed. The operator only advanced the probe along the guidance device of the manipulator,
which was adjusted on the basis of the preoperative plan, and punctured the target while maintaining the operative field using
robotic forceps. The position of the probe was monitored continuously with 3-D navigation and 2-D ISC images, as well as the
MR-compatible laparoscope. The ISC image was updated every 4 s; no artifact was detected.
Conclusion A newly developed MR image-guided surgical robotic system is feasible for an operator to perform safe and precise minimally
invasive procedures. 相似文献

Purpose
Endoscopes used in minimally invasive surgery provide a limited field of view, thus requiring a high degree of spatial awareness and orientation. Attempts at expanding this small, restricted view with previously observed imagery have been made by researchers and is generally known as image mosaicing or dynamic view expansion. For minimally invasive endoscopy, SLAM-based methods have been shown to have potential values but have yet to address effective visualisation techniques. 相似文献15.

Minimally invasive surgery (MIS) has had a tremendous impact on surgical practice in the last decades. For gastrointestinal surgery, construction of an anastomosis is often a critical part of the operation. Several technologies are used to perform an anastomosis in MIS. From smaller modifications of standard suturing techniques to the use of complex robotic surgery, suturing is still an essential part of MIS in this context. Stapling techniques have been adopted and modified from conventional open surgery. In the future, even more MIS procedures will be performed, especially if cancer surgery becomes more widely accepted. Further developments in MIS anastomotic techniques can be anticipated. 相似文献

- HEALTH CARE COSTS in the United States are climbing annually at a staggering rate. Technology often is blamed for rising health care costs; however, some medical advances, such as minimally invasive surgery (MIS), are critical to improving health care efficiency, enhancing the quality of care provided, and decreasing overall expenses.
- •
- SAVINGS OR PROFITS relating to technology may be difficult to measure quantitatively, but when surgeons and perioperative personnel have reached the peak of the learning curve for performing MIS procedures, complication rates drop significantly.
- •
- PATIENTS ARE EXPERIENCING the benefits of MIS (eg, decreased postoperative pain, shorter hospital stays and often no need for an overnight stay, ability to return to work sooner), all of which encourage technologically savvy consumers to seek MIS options. AORN J 82 (December 2005) 1006-1018.
