Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a fully automatic CT puncture positioner device. Background technique [0002] At present, when performing CT positioning and puncture operations, medical personnel first affix a CT positioning scale on the body surface of the puncture target, and through CT scanning, determine the puncture point and puncture angle according to the relationship between the metal scale point on the scan map and the puncture target. , and then select the puncture point on the human body to insert the needle, mainly relying on the experience and technical level of the operator to puncture the imaginary target. Repeated CT scans are required to confirm the position of the puncture needle. The operation is cumbersome and the radiation dose to the patient is large. [0003] At present, the Pinpoint system consisting of laser positioning, reconstructed three-dimensional image stereotaxic positioning and...

Problems solved by technology

[0002] At present, when performing CT positioning and puncture operations, medical personnel first stick a CT positioning scale on the body surface of the puncture target, and then determine the puncture point and puncture angle through CT scanning according to the relationship between the metal scale point on the scan map and the puncture target. , and then select the puncture point on the human body to insert the needle, mainly relying on the experience and technical level of the operator to puncture towards the imaginary target. Repeated CT scans are required to confirm the position of the puncture needle. The operation is cumbersome and the radiation dose to the patient is large.

[0003] At present, the Pinpoint system consisting of laser positioning, reconstructed three-dimensional image stereotaxic positioning and manipulator is applied to CT interventional therapy. It has more advantages and is a great progress in CT interventional therapy, but the equipment is expensive and it is difficult to carry out in primary hospitals
