Problems solved by technology

Because there is no bone support in the breast tissue, the tissue fluidity is strong. When the end of the puncture needle performs interventional surgery on the breast lesion, it is easy to cause the lesion to shift, which increases the difficulty of the operation and affects the accuracy of the operation.

Abstract

The invention discloses a tissue fixation device for breast interventional surgery that can work in the environment of a strong magnetic field for nuclear magnetic image navigation. The positioning column of the slide plate and the lead screw driving the baffle plate, the present invention can fix the breast tissue according to the size of the tissue in the breast interventional operation in the magnetic resonance imager, and overcome the inaccurate positioning and puncture caused by the movement and deformation of the tissue during the operation. Accurate questions can improve the accuracy of surgery, thereby improving the success rate of surgery.

Description

technical field [0001] The invention relates to the field of medical devices, and is particularly applied to breast interventional operations under the MRI environment. Background technique [0002] At present, many medical institutions at home and abroad have adopted breast interventional therapy in the nuclear magnetic environment to treat breast cancer, and patients are usually placed in the prone position during breast surgery. In the prone position, the patient needs to lie prone on the prone support, that is, the patient's body is located above the prone support, and the breast is in a natural drooping state, hanging in the prone support. Because there is no bone support in the breast tissue, the tissue fluidity is strong. When the end of the puncture needle performs interventional surgery on the breast lesion, it is easy to shift the position of the lesion, which increases the difficulty of the operation and affects the accuracy of the operation.
