Description

Medical rotary cutting equipment and movable control system thereof
Technical Field
The application relates to the technical field of medical treatment, in particular to medical rotary cutting equipment and a movable control system thereof.
Background
Currently, in breast biopsy procedures, a biopsy needs to be performed for a focal site by biopsy. When performing rotary-cut surgery for breast cancer, a physician may use markers to assist the surgical procedure. The marker is typically a small wire, particle or dye that is used to aid in locating and resecting the tumor. The markers are placed in the breast tissue prior to surgery by a painless or local anesthetic procedure for intraoperative positioning. The purpose of this is to help the surgeon to more accurately ablate the tumor and to preserve the surrounding normal tissue to a maximum extent. The markers are typically completely resected during surgery and pathologically inspected to ensure that the tumor is completely cleared. The marker can improve the accuracy and success rate of the operation and reduce the damage to normal tissues.
In the above technique, the physician needs to use a separate rotary cutter and a marker placement device to perform the operation, and after taking out the biopsy sample, a separate marker placement device is used to place the tissue marker at the biopsy site. A mammography examination is then performed to verify the location of the marker, which increases the surgical time and discomfort to the patient due to the necessity of two insertions, which also increase trauma to breast tissue, sometimes making it difficult to insert the marker placement needle into the exact location of the biopsy.
