Auxiliary location device and location system for puncturing

Abstract

The invention provides an auxiliary location device and a location system for puncturing. The auxiliary location device comprises a first surface and a second surface, wherein a plurality of primary location points and a plurality of secondary location points are respectively distributed on the first surface and the second surface; one primary location point is determined as a puncturing point bycollecting image data of a target point and the primary location points, a connection line between the target point and the puncturing point extends to the second surface, one secondary location pointis determined through a cross point, and a puncturing point and a puncturing angle can be determined through determined primary location point and the determined secondary location point which are arranged on the same straight line as the target point. The location system comprises the auxiliary location device, medical imaging equipment and data processing device. According to the auxiliary location device and the location system for puncturing disclosed by the invention, the puncturing point and the puncturing angle are determined before puncturing, so that the target point can be accurately located, and the puncturing accuracy is improved; furthermore, puncturing can be performed under the state that scanning is stopped, and safety of a puncturing process is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an auxiliary positioning device and a positioning system for puncturing. Background technique [0002] When lesions occur in internal tissues and organs of the human body, it is often necessary to use modern medical imaging technology such as CT (Computed Tomography, computerized tomography) technology or MRI (Magnetic Resonance Imaging, nuclear resonance imaging) technology to accurately locate the lesion, and then use the puncture needle, Interventional devices such as catheters and guide wires directly reach the lesion for biopsy or treatment. Using CT technology and MRI technology can determine the details of lesions or organs, so as to accurately determine the puncture point, puncture angle and puncture depth, avoid damage to blood vessels, nerves and spinal cord, and it is safe, accurate, fast, easy to operate, and less painful for patients. It has become an important me...
