Abstract

The invention relates to a body model device and method for detecting the navigation accuracy of a choledochoscope. The device includes a phantom body, the phantom body has a thoracic and abdominal cavity and an operation window connected to the thoracic and abdominal cavity, and the operation window is used for allowing the choledochoscope to enter the chest. In the abdominal cavity, the main body of the phantom is provided with multiple marking mechanisms, which are used for image registration. There are multiple positioning columns in the thoracic and abdominal cavity. One end of the positioning column is connected to the inner wall of the thoracic and abdominal cavity, and the other end of the positioning column has a At the target position end, a scale is provided on the positioning post. The body model device and method for detecting the accuracy of choledochoscope navigation can be used to detect and compare the accuracy of various navigation methods, and evaluate the clinical safety, stability and effectiveness of various navigation methods.

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 ...
