Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing equipment, and in particular to a tensile testing structure for a conveyor sheath control bending assembly. Background Technology

[0002] An adjustable bending sheath is a sheath assembly used in endovascular surgical procedures. Unlike ordinary sheath assemblies, this product allows the distal end of the sheath to bend within a certain angle range through the operation of a proximal handle. After bending, the tip of the sheath can be aligned with the target location, facilitating the manipulation of the bending path during interventional surgery. The bending function of the adjustable sheath is achieved through a bending control component, typically composed of a metal ring and a metal wire, which are welded together using laser welding.

[0003] After welding, the weld strength of the metal ring and wire needs to be tested to confirm whether the weld strength meets the design requirements. However, existing testing methods usually use a tensile testing machine, but because the parts being tested are relatively small, it is not easy to achieve precise control over the clamping method and clamping positioning, thus leading to inaccurate measurement data.
