AI Technical Summary
Traditional endoscopic biopsy devices lack remote independent posture fine-tuning and protection mechanisms in complex and slippery internal environments, leading to problems such as loss of positioning control, tissue rupture, and lesion slippage, making it difficult to achieve precise cutting.
It employs a structure consisting of a control handle, outer sheath, core wire, catheter, traction assembly, positioning and indexing assembly, and cutter. It converts linear tension transmission into rotational torque, and combined with negative pressure adsorption and anchoring needles, it achieves precise positioning and rotary cutting at the distal end.
It improves the efficiency of lesion detection, avoids loss of localization and tissue damage, and ensures the integrity and safety of pathological specimens.
