Background

At present, the percutaneous puncture operation is a minimally invasive operation, and doctors can be applied to lung tumor puncture, liver tumor puncture, percutaneous liver puncture biliary tract drainage, cancer pain blockage and the like. When performing percutaneous puncture surgery, a doctor often cooperates with Computed Tomography (CT) to assist the doctor in determining the puncture position of the puncture needle.

However, although a doctor can determine a lesion position by computer tomography, actually, when performing percutaneous puncture surgery, the doctor needs to rely on his own surgical experience, spatial geometry calculation, and hand feeling to complete the surgery. Therefore, if the doctor does not have sufficient experience during the puncture, the doctor must perform multiple computer tomography and adjust the needle insertion angle to confirm the needle insertion angle. This is time consuming and can be a serious injury to the patient. Furthermore, doctors and patients must be exposed to a radiation-intensive environment for a long time.

The former guide device can be fixed on a bed plate of a computer tomography. When a patient lies on the bed board, a doctor can use the guiding device to assist in positioning the needle inserting point of the puncture needle. However, the general guide device has a complicated structure and is not easy to operate, and a doctor cannot intuitively and accurately determine the needle insertion point position of the puncture needle. The guiding device still does not assist the physician in determining the exact location of the needle insertion site. In addition, since a general guide device does not have a function of adjusting the angle of the puncture needle, an inexperienced doctor cannot grasp the insertion angle of the puncture needle, and the guide device is poor in stability and is likely to be displaced.
