Abstract

The invention belongs to the field of medical apparatuses, and particularly relates to a tactile sensation visualization puncturing surgery navigation system based on an augment reality technique. According to the tactile sensation visualized puncturing surgery navigation system disclosed by the invention, a six-freedom-degree mechanics sensor is connected with a puncture needle to obtain puncturing mechanics data when the puncture needle punctures parenchyma; after being analyzed and treated by a multi-dimensional force measuring data analyzer, the puncturing mechanics data is transmitted toan Unity3D game engine of a computer client through wireless driving for data visualization displaying; visualization display comparison is performed between the analyzed and treated puncturing mechanics data and a parenchyma force-time mathematical model obtained after simulation of repeated same puncturing experimental data, so that a doctor can more intuitively observe the differences between the analyzed and treated puncturing mechanics data and the parenchyma force-time mathematical model obtained after simulation of repeated same puncturing experimental data, when the difference value ofthe two puncturing force is larger than a set threshold, the situation that the puncture needle punctures a blood vessel or necrosis tissue can be judged; and puncturing paths can be changed in timeor puncturing can be stopped for sampling referring to the visual sense visualization navigation, so that the puncturing precision can be improved, and the puncturing error rate can be reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an augmented reality-based tactile visualization puncture surgery navigation system. Background technique [0002] Malignant tumors seriously endanger human health and life. In recent years, the morbidity and mortality have gradually increased. The correct diagnosis requires a combination of clinical, imaging and pathological examinations in order to make a more accurate diagnosis. Among them, pathological examination plays a key role in the selection of treatment options. Needle biopsy is the main method to obtain tumor histopathological diagnosis. The main methods of needle biopsy are: traditional puncture, ultrasound-guided puncture, MRI-guided puncture, and CT-guided puncture. Vision and touch are indispensable and important references in doctors' operations, especially 3D vision and tactile visualization. In 1976, Haaga used CT-guided percutaneous lung biopsy fo...
