Surgical clip
10368875 · 2019-08-06 · ·

A surgical clip for a surgical clip applicator includes at least one pair of clip arms. Each clip arm has a distal end and a proximal end. The two clip arms are connected to each other at the proximal ends of the clip arms and form a clip throat. A tangent angle between a tangent to a neutral fiber of a clip arm and a perpendicular to a longitudinal axis of the clip increases over the entire length of the clip arm substantially continuously.

Large Scale Metal Forming

In certain embodiments described herein, a heated line forming system includes a heating coil system configured to produce a heated line on a surface of a metal part. The heated line forming system also includes an air knife cooling system configured to maintain a dry area for the heated line, and to direct a coolant (e.g., cooling water, liquified gases such as liquid argon, solidified gases such as carbon dioxide snow, and so forth) around the heated line via a spray mechanism such that the coolant does not flow or splash into the heated line on the metal part. In certain embodiments, the heated line forming system includes multiple induction coils arranged along a line and spaced a short distance apart, but which, when operated simultaneously together, form a heated line on a surface of a metal part.

Method for Automated Straightening of Welded Assemblies

An automated method for straightening/correcting deformations made to panels when welded to metallic structural components is disclosed. In the train industry, when an aluminum component, such as a vehicle's exterior shell, is welded to hidden structural parts, deformations thereon may occur. Such deformations need to be subsequently corrected, and the present method uses robots and optical measuring of the deformed surfaces to conduct a straightening thereof. The method includes four main steps. First, the deformed surface is scanned with an optical sensor to make physical measures/characterizations thereof. Second, the gathered data are compared with the desired resultant by a software. Third, once the comparison is done, the software performs an analysis to select the proper parameters to be used in the straightening method that will be applied at each area requiring straightening. Finally, a robot executes the operations specified by the software to perform the straightening process.
