    Abstract: Bone reduction forceps provide both continuous and discrete adjustment of force. A worm gear rotatably attached to one arm of the forceps engages a rack attached to another arm of the forceps to provide both the continuous and discrete force adjustment. Buttress threads on the worm and/or the rack allow for rapid closure by squeezing the handles of the forceps. Rotating the worm gear allows for fine adjustment of closing force. A five-bar linkage provides increased mechanical advantage and an extra degree of freedom, compared to conventional forceps. Interchangeable tips provide flexibility, allowing a user to customize the forceps to a task or the user's preferences.

    Abstract: A method or corresponding apparatus in an example embodiment of the present invention relates to penetrating a particulate substrate using a compact, lightweight, low-energy, reversible, and dynamic device for burrowing through particulate substrates. In one preferred embodiment, the apparatus includes at least one vessel and a displacement module coupled with the vessel. The actuation of the displacement module fluidizes the particulate substrate proximate to the vessel and thereby reduces resistance of the particulate substrate to movement of the vessel and causes further penetration of the apparatus through the particulate substrate. The example embodiment utilizes volume contraction and localized fluidizing to efficiently move through substrates.

    Abstract translation: 本发明的示例性实施例中的方法或相应的装置涉及使用紧凑的，重量轻的，低能量的，可逆的和动态的装置来穿透颗粒基质，用于穿过颗粒基底。 在一个优选实施例中，该装置包括至少一个容器和与该容器连接的位移模块。 位移模块的致动使颗粒基板在容器附近流动，从而降低颗粒基质对容器移动的阻力，并引起装置进一步穿透颗粒基质。 该示例性实施例利用体积收缩和局部流化来有效地移动通过基底。
