To describe a suction-based grasping tool for the surgical removal of irregular-shaped and nonferromagnetic intraocular foreign bodies.
A surgical tool with suction capabilities, consisting of a stainless steel shaft with a plastic handle and a customizable and interchangeable suction tip, was designed in order to better engage and manipulate irregular-shaped in-traocular foreign bodies of various sizes and physical properties. The maximal suction force and surgical capabilities were assessed in the laboratory and on a cadaveric eye vitrectomy model.
The suction force of the water-tight seal between the intraocular foreign body and the suction tip was estimated to be approximately 40 MN. During an open-sky vitrectomy in a porcine model, the device was successful in engaging and firmly securing foreign bodies of different sizes and shapes.
The suction-based grasping tool enables removal of irregular-shaped and nonferromagnetic foreign bodies.
描述一种用于手术摘除不规则形状和非铁磁性眼内异物的基于吸力的抓取工具。
设计了一种具有吸力功能的手术工具，它由带有塑料手柄的不锈钢杆以及可定制和可互换的吸头组成，以便更好地抓取和操作各种尺寸和物理特性的不规则形状眼内异物。在实验室和尸体眼球玻璃体切除模型上评估了最大吸力和手术能力。
估计眼内异物与吸头之间的水密密封吸力约为40 MN。在猪模型的开放式玻璃体切除术中，该装置成功抓取并牢固固定了不同尺寸和形状的异物。
基于吸力的抓取工具能够摘除不规则形状和非铁磁性异物。
