  • Patent number: 11950821
    Abstract: A surgical tool for positioning a surgical device includes a gripping portion; a rod protruding from the gripping portion; and a coupling system. The coupling system comprises an axial retention assembly comprising, at a free end of the rod, two opposite semispherical portions, wherein respective flat surfaces are separated from each other by an axial notch made partially along the rod, and a central clutch movable between a locking position and a disengagement position. In the locking position, the central clutch approaches the free end of the rod and is interposed between the two semispherical portions, preventing reciprocal approach thereof so as to block the two semispherical portions within a seat of said surgical device. In the disengagement position, the central clutch moves away from the free end such that the two semispherical portions can approach to allow the tool to come out of the surgical device.

  • Patent number: 7550723
    Abstract: A preliminary processing technology for a sample locally cuts out a sample part of a device to be analyzed and processes it into a needle-like projection, and a technology of realizing SAP analysis on an atomic level by ensuring stabilized ion evaporation sequentially even in the case of a sample of multilayer structure including an element layer of small evaporation electric field. The preliminary processing method for a sample used on atom probe apparatus comprises a step for cutting the desired observing part of the sample into a block using an FIB equipment, a step for transferring the sample block onto a sample substrate and fixing the sample block in place, and a step for processing the sample block fixed onto the sample substrate into a needle-point shape by FIB etching. The sample processed into a needle-point shape is shaped such that the layer direction of the multilayer structure becomes parallel to the longitudinal direction of the needle.

  • Patent number: 7511289
    Abstract: A working method of performing beam assist deposition or beam assist etching of a sample comprises irradiating a focused charged particle beam onto a region of the sample, and blowing a predetermined gas through a gas blowing nozzle toward the sample region while the focused charged particle beam passes through a passage in a side portion of the gas blowing nozzle and irradiates the sample region. The passage may be a slot provided in the side portion of the gas blowing nozzle such that the focused charged particle beam passes through an inside of the slot. The slot terminates at one end near a tip of the gas blowing nozzle, and the one end of the slot terminates at and opens into the interior of the gas blowing nozzle.
