Problems solved by technology

[0002] In the process of robot-assisted ultrasonic scanning, the existing experimental models mainly have the following deficiencies: First, the complete human spine model is bulky and heavy, and water is usually used to imitate human muscles, and it takes a long time to fill water, so the experimental preparation is quite difficult. Second, the shape of the human spine in a single model is fixed, and the scan data is limited; third, the model is a "dead" model, which is quite different from the real human body. One of the main differences lies in the regular breathing exercise of the human body. Practical docking problems. At present, there are high-precision commercial human spine models, which can accurately display the skin contour and spine structure of the human back. However, the economic cost is high, and it is difficult to simulate human bodies of different ages and body types with only a single model. , it is more difficult to simulate the spontaneous breathing movement of the human body, and it is even more difficult to obtain data with sufficient sample size and conduct safety testing and evaluation based on practical research

Embodiment 1

[0038] The test platform simulates the coupling relationship between the probe and the back of the human body under real ultrasonic scanning conditions, and collects various data on the coupling between the ultrasonic probe and the back of different human bodies. The test method of the platform includes the following steps:

[0039]1) Preparation before the test. Adjust the knob 2 to change the height of the telescopic rod 1 inside the box shell 6, thereby changing the deflection curve of the flexible slat 8, and then changing the overall curve of the spine skeleton; changing the thickness of the skin-like outer silicone layer 13 to simulate human bodies of different shapes the thickness of the fat layer; open the valve 10 to inject a sufficient amount of pure water into the box shell 6 and seal it with a water plug 11; start the motor and the reducer group 17 to drive the crank plate 18 to rotate, thereby driving the four-bar linkage Do periodic reciprocating motion, and then...

Embodiment 2

[0044] The test platform simulates the real human body ultrasonic scanning situation, performs ultrasonic imaging and interprets the imaging results, including the following steps:

[0045] 1) Adjust the three knobs to adjust the telescopic rod, so that the 3D printed adjustable spine skeleton maintains a specific curvature; select a skin-like silicone layer of a specific thickness and fix it on the top of the box shell, simulating the thickness of the fat layer of the human body; open the valve Inject a sufficient amount of pure water into the box and seal it with a water plug; adjust the hinged hole between the crank plate and the box shell, select the appropriate crank length, select a specific speed, start the motor, and drive the box to do periodic reciprocating motion.

[0046] 2) The ultrasonic probe is clamped by the multifunctional manipulator, and the starting position of the probe on the surface of the skin-imitating outer silicone layer on the box is adjusted and de...

Abstract

The invention discloses a human body spine ultrasonic imaging scanning testing platform with a respiratory movement simulation function. The platform comprises two parts, namely an adjustable spine framework and a respiratory movement simulation mechanism. According to the platform, simulation of different section curves of a human body spine is realized by the adjustable spine framework; and simulation of human respiratory movement is realized through a four-bar mechanism driven by a motor, so that on one hand, abundant human body spine scanning materials are provided for robot-assisted medical ultrasonic imaging scanning, and on the other hand, fresh and alive simulation of the ultrasonic scanning process is realized through dynamic fluctuation change of the model. The platform can serveas a test platform for robot-assisted ultrasonic imaging scanning, and provides effective verification for the reliability, the safety and the ultrasonic imaging scanning effect of the machine-type ultrasonic scanning.
