As the “hub component” of the endoscope system, the primary function of stainless steel endoscope joints is to achieve stable assembly of various core components. It connects key parts such as the endoscope body, light source catheter, imaging module, biopsy channel, etc. through precision threads, buckles, or plug-in structures. With the high strength and deformation resistance of stainless steel material, it ensures the structural integrity of the equipment during operation (such as angle adjustment, insertion and extraction docking), avoiding equipment failure or operational deviation caused by loose connections.
