Problems solved by technology

Traditional ultrasound image-guided puncture has certain limitations. When the puncture instrument starts to puncture outside the ultrasound image plane, the puncture instrument can only be observed in the ultrasound image after the tip of the puncture instrument enters the imaging plane of the ultrasound image. Therefore, The puncture direction cannot be guided in real time and continuously during the puncture process; the guide needle grooves on some new ultrasonic probes solve the above problems to a certain extent, allowing the puncture instruments to move along the guide needle grooves, but this method makes the puncture instruments limited Because it can only move along the plane of the ultrasound image, this method controls the puncture direction more precisely and limits the flexibility of the puncture operation.

Embodiment Construction

[0019] The system includes a set of ultrasonic diagnostic equipment (including ultrasonic probe and host), one or more puncture instruments (syringes, biopsy needles / forceps, radiofrequency ablation probes, cryotherapy probes, etc.), a three-dimensional space position measurement device, a or multiple position markers or sensors, and a set of image fusion workstations.

[0020] figure 1 It schematically shows the fixing and connecting relationship of each part of the present invention. The three-dimensional space position measuring device 6 is fixed on the handle or shell of the ultrasonic probe 3, and the position marker or sensor 7 is fixed on the handle or shell of the puncture instrument 2. The image fusion workstation 8. Establish a data connection with the three-dimensional space position measuring device 6 and the ultrasonic diagnostic instrument host 4 through wired or wireless means.

[0021] When the system is in use, the ultrasonic probe 3 touches the human body su...

Abstract

The invention discloses an aided navigation system of puncture operation under ultrasonic image, belonging to the navigation field of the puncture operation based on three-dimensional spatial orientation and ultrasonic image, the aided navigation system is characterized in that a three-dimensional spatial position measurement device fixed on a handle or a shell of an ultrasonic probe of an ultrasonic diagnostic equipment performs three-dimensional space positioning on a position marker or a sensor fixed on the a handle or a shell of a puncture instrument so as to compute relationship of the spatial position and direction of the tip of the puncture instrument and ultrasonic image plane by image fusion workstation, and display computed result and ultrasonic image; the aided navigation system can be applied in puncture operation where the puncture instrument and ultrasonic image plane form any angle, the puncture direction of the puncture instrument is guided accurately in real time during puncture, and the puncture instrument is enabled to accurately puncture so as to arrive at a target area in the ultrasonic image.

Description

technical field [0001] The invention relates to the field of puncture surgery navigation based on three-dimensional space positioning and ultrasonic imaging. In particular, it relates to an auxiliary navigation system and method for puncture surgery guided by ultrasound images. Background technique [0002] Ultrasound image-guided puncture is widely used in surgical fields such as tumor biopsy, drug injection, radiofrequency ablation therapy, and cryotherapy. This operation assists the tip of the puncture instrument to accurately reach the designated treatment area through the guidance and positioning of ultrasound images. Traditional ultrasound image-guided puncture has certain limitations. When the puncture instrument starts to puncture outside the ultrasound image plane, the puncture instrument can only be observed in the ultrasound image after the tip of the puncture instrument enters the imaging plane of the ultrasound image. Therefore, The puncture direction cannot be...
