Problems solved by technology

[0003] There have been some research and improved surgical navigation systems, such as the TUSS (Queen's University, Canada) mentioned in the paper "Spinal Needle Navigation by Tracked Ultrasound Snapshots", but they all use computer screens to display navigation information, such as surgical paths and surgical instruments. Three-dimensional models and ultrasonic two-dimensional images and CT / MRI three-dimensional images of various modal information, but the doctor has to switch the field of view back and forth between the patient and the screen during the operation, which is very inconvenient and affects the continuity of the operation

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] figure 1 It is a connection diagram of hardware equipment of the present invention. The ultrasound probe 101 is connected to an ultrasound imaging device 102, and then connected to an image workstation 107 through an image acquisition card 103 to collect ultrasound images. Ultrasonic probe 101, puncture needle 104, and head-mounted virtual reality device 105 have all been equipped with reflective balls of optical positioning equipment, and their position information is transmitted to image workstation 107 through position tracking device 106, and image workstation 107 will collect the position information. Process with real-time ultrasound image information to realiz...

Abstract

The invention relates to a navigation system and method for 3D virtual ultrasonic guidance puncture, to meet clinical puncture requirements in a minimally invasive interventional operation. The navigation system comprises a three-dimensional visual display device, an ultrasonic imaging device, an ultrasonic probe, an image collecting card, an image working station, a spatial location device, a puncture needle and designed and developed supporting software, and functions such as three-dimensional scene rendering and display, hardware device calibration and operation path planning are achieved. According to the navigation method for puncture of the navigation system, by correcting tumor position changes caused by breathing movement and patients' movement in the operation process, puncture precision of the navigation system is improved. A virtual reality technology is applied to ultrasonic operation navigation, three dimension and flexibility of display are enhanced, and a doctor is helped to finish an operation better and more quickly.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a 3D virtual ultrasound-guided puncture navigation system and method. Background technique [0002] At present, in clinical practice, ordinary B-ultrasound shows two-dimensional cross-sectional images. Two-dimensional images have many limitations in surgery, especially in the puncture process. Only visible on the ultrasound image plane. This means that, in most cases, the doctor cannot see the tip of the needle on the ultrasound plane, making it difficult to move it accurately to the target area. [0003] There have been some research and improved surgical navigation systems, such as the TUSS (Queen's University, Canada) mentioned in the paper "Spinal Needle Navigation by Tracked Ultrasound Snapshots", but they all use computer screens to display navigation information, such as surgical paths and surgical instruments. Three-dimensional models and ultrasonic two-dimensional images...
