Calibrated surgical probe

A microsurgical probe tip and method of using same are disclosed. One embodiment of the microsurgical probe tip comprises: an outer cutting member, comprising a first tube having a wall, a closed end and a port formed in the wall near the closed end; an inner cutting member, comprising a second tube coaxial with and operable to move in a reciprocating motion within the first tube and having a first end operable to be coupled to a driving mechanism and a second end with a cutting edge for cutting tissue; a first alignment mark on the outer cutting member at a first predetermined position adjacent to the port; and a second alignment mark on the inner cutting member at a second predetermined position adjacent to the cutting edge of the inner cutting member, wherein the second alignment mark is visible through the port and operable to be aligned with the first alignment mark such that when the first and second alignment marks are aligned, a preferred relative positioning between the inner and outer cutting members is achieved. The microsurgical probe tip can further comprise one or more radial alignment marks on the inner cutting member, wherein the radial alignment marks are parallel to one another at fixed intervals from one another and positioned so that one or more of the radial alignment marks are visible through the port so as to indicate the relative lateral positioning between the inner cutting member and the outer cutting member. The radial alignment marks can be made by a method, or combination of methods, such as laser cutting, inkjet printing, and mechanical scribing. The driving mechanism can be a pneumatic driving mechanism, an electro-mechanical driving mechanism, and/or a magnetic driving mechanism. The microsurgical probe tip can further comprising a plurality of gauge marks on an outer surface of the outer cutting member, wherein the gauge marks are parallel to one another at a fixed interval (e.g., 1 millimeter) from one another and positioned so that the gauge marks can be used as a measuring tool in a surgical environment

Device and method for joining and tacking sections for transportation vehicles

A device and method for joining and tacking several individual components independently of shape and/or size to form inherently rigid, transportable sections for transportation vehicles, such as an aircraft is disclosed. According to one embodiment of the invention, the individual components may be spatially positioned relative to each other independently of shape and/or size. The spatial positions of the individual components may be determined by a measuring device, such as a laser measuring device, and varied via several positioning devices until a preset spatial position of the individual components has been reached in which the individual component are tacked together to form a section. In another embodiment, the positioning devices may be designed as base positioners, a first lateral positioner, a second lateral positioner, an upper positioner as well as an inner positioner. Joining and tacking of several individual components 1 may form varying sections such as sections with varying cross sectional geometries and/or cross sectional dimensions and/or linear dimensions for different types of aircraft or for derivatives of the same aircraft types. In addition, the sections may have two working platforms on either side of the section.
