A device for loading a surgical knotting element on an applicator tool. One embodiment of the device includes a channel dimensioned to receive an applicator tool comprising a coupling. A surgical knotting element comprises a coupling complementary to the coupling of an applicator tool and a suture path. A carriage receives the surgical knotting element. The carriage is moveable in a transverse direction relative the channel between a first position where the knotting element is misaligned with the channel and a second position where the couplings are engaged with one another.

Loader for knotting element

A conventional stud welding tool is substantially improved by providing the tool with an electrode with an adjustable aperture capable of grasping studs with a variety of sizes. The adjustable aperture is in the form of a chuck having a plurality of sliding fingers movable along intersecting axes and positionable along these axes to form an aperture of a desired diameter. The fingers have a threaded exterior surface, and the chuck includes a wheel having a threaded interior surface for engaging the threaded exterior surfaces of the fingers for moving the fingers along their axes in response to rotation of the wheel. The chuck is automatically closed and opened by a control circuit in response to the condition of a variety of sensors connected to the control circuit. Also, a collating strip of studs and a feed assembly is used to automatically deliver studs to the electrode under control of the control circuit.

Automatic chuck loadable stud welding tool and magazine therefor

A system for automatically feeding studs to the electrode of a manual stud welding tool. The system comprises a magazine associated with the tool. The magazine receives a tandem row of studs mounted in and collated by a disposable mounting and collating strip assembly. A drive assembly is associated with the magazine to advance the mounting and collating strip assembly such that each stud, when it becomes the forwardmost stud of the tandem row, is properly positioned with respect to the tool to be welded to a workpiece.
