超微创磁锚定腹腔镜系统的研制

摘要

该文介绍了一种超微创磁锚定腹腔镜系统，包括体外磁性引导手柄和体内的磁锚定腹腔镜。磁锚定腹腔镜包括外套管、数据线、摄像头、高色温LED灯和两块内磁铁。磁锚定腹腔镜体积微小，可通过传统腹腔镜戳卡进入腹腔，通过与体外磁性引导手柄相吸实现腹腔内的定位、导航及调节视场，从而在工作状态不占用戳卡空间。利用该系统不仅可以实现基于单个传统腹腔镜戳卡的单孔腹腔镜手术，还可实现减戳卡的传统腹腔镜手术，增强手术微创性的同时降低手术难度，其临床应用将优化微创技术，造福广大患者。%A magnetic anchoring supermicroinvasive laparoscopic system, including in vitro magnetic navigation handle and in vivo magnetic anchor laparoscopy is introduced. The magnetic anchor laparoscopic comprises an outer cannula, two data lines, a camera, a high color temperature LED light and two inner magnets. It is tiny enough to enter the abdominal cavity through conventional laparoscopic trocar and achieve orientation, navigation as wel as adjustment thefi eld of view within the abdominal cavity by attracting with the in vitro magnetic handle, thus it does not take up space of the laparoscopic trocar in working state. The system which can not only apply in single-port laparoscopic surgery based on a single traditional laparoscopic trocar but also apply in traditional laparoscopic surgery with less trocar, wil enhance the extent of minimaly invasive surgery and reduce the operation diffi culty at the same time. The clinical application of the system wil optimize the minimaly invasive techniques and benefi t the patients.
