Motion control system for collection of puncture test data information and application method thereof

Abstract

The present invention relates to the technical field of medical devices, especially to a motion control system for collection of puncture test data information. The system comprises a power supply controller, a computer, a motor drive module, an electric control displacement bench, a puncture needle, a B-mode ultrasound instrument, a B-mode ultrasound probe, a force sensor and a camera. The powersupply controller is configured to supply a power supply to the computer and the motor drive module, an output end of the computer is connected with an input end of the motor drive module, an output end of the motor drive module is connected with the electric control displacement bench, the puncture needle, the B-mode ultrasound probe and the force sensor are installed on the electric control displacement bench, the force sensor is installed at the tail portion of the puncture needle, the motor drive module is configured to drive the motion of the puncture needle and the B-mode ultrasound probe, and the force sensor, the camera and an output end of the B-mode ultrasound instrument are connected with a computer control module to transmit collected information to the computer. The motion control system is high in precision, simple in operation and high in computer automation operation degree, and can be widely applied to teaching work.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a motion control system for collecting puncture experiment data information and a method for using the same. Background technique [0002] At present, the teaching of puncture experiments has been popularized in teaching work, and there is no intelligent operating system that can be used for puncture experiments in school teaching, so that the teaching work and students' practice only stay in manual operation, that is, when doing puncture experiments, generally They are all carried out on a simple test frame. When the puncture needle punctures the prosthesis or other experimental body membranes, the distance and direction of the puncture are manually controlled, and the image acquisition is also manually changing the detection position of the B-ultrasound probe. This method is not only difficult to accurately control The distance and direction of the puncture needle, an...

[0002] At present, the teaching of puncture experiments has been popularized in teaching work, and there is no intelligent operating system that can be used for puncture experiments in school teaching, so that the teaching work and students' practice only stay in manual operation, that is, when doing puncture experiments, generally They are all carried out on a simple test frame. When the puncture needle punctures the prosthesis or other experimental body membranes, the distance and direction of the puncture are manually controlled, and the image acquisition is also manually changing the detection position of the B-ultrasound probe. This method is not only difficult to accurately control The distance and direction of the puncture needle, and the experimental data such as the position of the puncture needle in the prosthesis or other experimental objects and the position of internal nodes cannot be collected in real time, and the accuracy of the experimental data is low

[0003] When performing a puncture test, since everyone has a different feeling for the distance adjustment of the puncture needle and the B-ultrasound probe, this kind of blind puncture test body membrane based on experience and feeling is too subjective, resulting in uneven puncture test data collected. Unable to meet higher teaching requirements
