Abstract

The invention relates to a body model device and method for detecting navigation accuracy of a choledochoscope. The device comprises a phantom main body, wherein the phantom main body is provided witha pleuroperitoneal cavity and an operation window, the operation window communicates with the pleuroperitoneal cavity and is used for the choledochoscope to enter the pleuroperitoneal cavity, a plurality of label mechanisms are arranged on the phantom main body and are used for image registration, multiple positioning posts are arranged in the pleuroperitoneal cavity, one end of each positioningpost is connected to an inner wall of the pleuroperitoneal cavity, target ends are arranged at the other ends of the positioning posts, and graduations are arranged on the positioning posts. The bodymodel device and method for detecting navigation accuracy of the choledochoscope can be used for detecting and comparing accuracy of various navigation methods, and the clinical safety, stability andeffectiveness of various navigation methods is evaluated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a body model device and method for testing the navigation accuracy of a choledochoscope. Background technique [0002] When the choledochoscope is used for diagnosis and treatment in the small bile duct, the precise location of the lesion and the navigation accuracy of the choledochoscope are the most important factors to ensure the efficacy of patients and medical safety. Clinical use of intraoperative X-ray contrast, intraoperative ultrasound, intraoperative small CT or MR, preoperative CT, MR images to reconstruct 3D models of organ tissues, and surgical navigation through infrared navigation systems and magnetic navigation systems. There may be various reasons or external interference during surgical navigation, resulting in registration errors, registration errors, etc., affecting positioning accuracy and clinical navigation accuracy. At present, there is no human body model ...
