Ultrasound intervention puncture needle guidance monitoring system and method

Abstract

The invention relates to the technical field of medical ultrasounds, in particular to an ultrasound intervention puncture needle guidance monitoring system and method. The ultrasound intervention puncture needle guidance monitoring system comprises a medical ultrasonic transducer, a puncture needle positioning frame, an axial optical displacement sensor, a radial angle optical displacement sensor and an ultrasonic image monitoring device. Due to the design of the axial optical displacement sensor and the radial angle optical displacement sensor, the advantage that the displacement is detected through the optical displacement sensors in a non-contact and high-precision mode can be used; the axial displacement value and the radial angle value of a puncture needle are automatically fed back in real time, and the problems that in the prior art, an angle-fixed guidance puncture frame does not completely covert the distribution area range of a target spot, and the needle tip position and the needle path route of the puncture needle can not be calculated are solved; medical workers are helped to adjust the needle inlet angle in advance, and damage caused by multiple times of puncture to patients is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical ultrasound, in particular to an ultrasonic interventional puncture needle guidance monitoring system and a monitoring method. Background technique [0002] In the current clinical application of medical ultrasonic interventional puncture needle guidance, there are many solutions, three of which are briefly listed. The first type: use the electromagnetic positioning and navigation products of Ascension Company of the United States; the basic principle is to emit a specific sequence of electromagnetic fields (transmitters) in an area, and use more than two receiving coil sensors (sensors) to place one or more sensors according to the designed positional relationship. Two are fixed on the medical ultrasonic transducer; one of the sensors needs to be put into the trocar on the inner wall of the puncture needle, and the axial value of the sensor and the trocar is guaranteed to be the same as the design...
