Constant-speed constant-pressure plain scanning guide rail of B ultrasound probe

Abstract

The invention provides a mechanical device and a method for achieving constant-speed, constant-pressure and non-missing plain canning of a B ultrasound probe. The device comprises a guide rail assembly and a guide rail assembly bracket; the guide rail assembly comprises an X axial guide rail, a Y axial guide rail, a Z axial guide rail, and a rotatable B ultrasound probe clamp which is mounted at the bottom end of the Z axial guide rail; a pressure sensor and an angle measuring sensor are arranged on a lower bracket of the Z axial guide rail; the guide rail assembly is connected with the guide rail bracket through a rotating shaft and can be rotated around the rotating shaft; the guide rail assembly rotates to drive a motor and a rotating speed reduction device; the transmission mode of the guide rail is performed through a precision lead screw or a gear belt; the B ultrasound probe is driven by a driving mechanism to axially move at constant speed in the X, Y and Z directions; meanwhile, the probe is swung under the effect of the probe clamp rotating mechanism; a track assembly is driven by the rotating mechanism to rotate to adjust the vertical relationship between the ultrasound direction and the detection surface, so as to achieve constant-pressure, constant-speed, non-missing and overlapping-free scanning of the B ultrasound probe.

Description

technical field [0001] The invention relates to the medical field, in particular to a mechanical device and a method for realizing uniform-speed and constant-pressure flat scanning of a B-ultrasound probe without omission. One of the specific applications of the device is fetal prenatal screening, which is used for prenatal ultrasound examination of fetus, ultrasound diagnosis of fetal heredity and deformity diseases. Background technique [0002] In order to realize the B-ultrasound probe’s constant-speed and constant-pressure flat scan, Siemens’ automatic breast volume scanner (ABVS) has designed a flat scan device that requires the detection site to be flat, that is, to flatten the detection site, only It is suitable for relatively flat superficial organs. This device cannot inspect deep organs and uneven human body parts, let alone prenatal inspection of pregnant women. Because the protruding abdomen of pregnant women varies from person to person, the pressure of the p...
