Abstract

The invention discloses a perspective navigation method used for a C-arm type X-ray machine, which utilizes an adapter of an image intensifier and is matched with a C-arm for use. The perspective navigation method comprises the steps of initializing a navigation control system; carrying out perspective navigation puncture positioning; setting a crisscross positioning point set by an X-axis laser head and a Y-axis laser head through a positioning control system, sending information to a command controller and carrying out laser positioning frequency flicker display; carrying out the positioningby an integrated positioning tracking system; judging whether the puncture part of a patient generates displacement or not; amending the original set value according to the actual displacement value;constituting an integrated three-dimension imaging and CT path graph by using information emitted by the command controller and the actual displacement value; and using data of the actual displacement value and the three-dimensional imaging and CT path graph for forming a new coordinate, carrying out puncture according to the new coordinate of the actual displacement value and sending the information to a data acquisition device. The perspective navigation method minimizes the harm of an operation to human body, thereby having very high safety factor.

Description

Technical field [0001] The invention relates to a perspective navigation method, in particular to a perspective navigation method for a C-arm X-ray machine, and belongs to the field of medical equipment. It is a device that uses the unique fluoroscopy function of the C-arm X-ray machine, combined with laser positioning, image intensifier adapters, and Windows operating system software to complete the lesion tracking and puncture function. Background technique [0002] At present, the electromagnetic positioning system that has been used in clinical practice at home and abroad is relatively complicated, and its high price and complicated operation are only suitable for complex surgery and scientific research in Grade A hospitals above the third level. Due to the current vigorous development of minimally invasive surgery, the sales of C-arm X-ray machines are also increasing rapidly, and the market has an increasing demand for high-quality and inexpensive navigation systems and the...
