Description

Puncture path planning device and ultrasound system

technical field

The embodiments of the utility model relate to the field of medical technology, and in particular, to a puncture path planning device and an ultrasound system.

Background technique

Currently, breast biopsy treatment methods rely on non-fixed two-dimensional hand-held ultrasound images or imaging information from radioactive mammography images for needle guidance.

When the puncture needle is guided based on the image information of mammography images, the breast area is fixed during the scanning process, which can theoretically achieve accurate positioning and path planning. However, due to the radioactivity of mammography, it is easy to cause damage to patients and medical staff. extra damage. Also, mammography and puncture are not performed simultaneously, so the movement of the breast region can lead to inaccurate spatial positioning.

The two-dimensional hand-held ultrasound images are non-radioactive and can be used for real-time surgical guidance during the puncture process. However, due to the non-fixation of the breast region, this method relies on the doctor's operating experience. In addition, noise is included in the two-dimensional ultrasound imaging process, which may lead to inaccurate puncture paths and unclear puncture depths during the puncture guidance process, which may easily cause secondary damage to the patient.
