TECHNICAL FIELD

BACKGROUND

During puncture, a puncture needle is used to pierce a body cavity to extract secretions for testing, inject gas or contrast agents into the body cavity for a contrast examination, or inject a drug into the body cavity, so as to facilitate diagnosis and treatment, such as blood tests, blood transfusion, infusion and catheter inserting for angiography in brain or spinal cavity. For diagnosis or treatment, puncture comprises, but is not limited to, subdural puncture, ventricular puncture, cerebrovascular puncture, lumbar puncture and thoracic cavity puncture and more. In addition, puncture can also be used to construct a channel for following entrance of an operative instrument.

In the prior art, during puncture, a doctor usually acquires image information by means of computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, X-ray, etc., determines a puncture location and a puncture angle with an aid of computer-aided settings, formulates a corresponding surgical plan, before performing the puncture according to a formulated plan. Puncture described above is mainly performed manually relying on a preoperative plan, experience of the doctor and an observed situation, which makes an accuracy of the puncture susceptible to a plurality of factors, makes an accurate location impossible, while increasing learning curves based on clinical imaging for an operator, and enhances risk of an operation.

In addition, on one hand, compared with an ultrasonic guidance, CT has a limited resolution for soft tissue organs, which leads to a blurred display of a boundary between a target anatomical tissue and a surrounding tissue, causes lesions to appear rarely in CT, and results in difficulty in an accurate puncture and intervention operation; while on another hand, MRI has a high resolution for a soft tissue, and therefore can be configured to identify and locate the lesions, and ultrasound can detect an image in a real time. Thus a combination of the ultrasound and the MRI is conducive to achieve an accurate puncture and interventional operation.
