Prostate detection device

Abstract

The invention discloses a prostate detection device. The device comprises a lifting mechanism, a stepper and a mechanical arm body with rotating and stretching functions. The mechanical arm is rotationally connected to the lifting mechanism. The stepper is rotationally connected to the mechanical arm; the stepper comprises a rotatable moving part; the end of the moving part is fixedly connected with an installation part used for installing a probe; the mechanical arm is provided with a detection element used for monitoring the rotating and stretching displacement of the mechanical arm; and thestepping device is also provided with a detection element used for monitoring the rotating and moving displacement of the stepping device. The device can move along with the movement of a patient andsynchronously feed back the variation of displacement, meanwhile, the constant pressure of the ultrasonic probe on the prostate is kept, image deformation is reduced to the maximum extent, and the accuracy of a detection result is guaranteed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a prostate detection device. Background technique [0002] In recent years, with the development of imaging technology, especially the wide application of MRI examination technology, the detection rate of prostate cancer foci has become higher and higher, but prostate biopsy is still the "gold standard" for the diagnosis of prostate cancer. MRI examination has high resolution for prostate tissue, high lesion detection rate, and has good guiding significance for puncture positioning. The combination of MRI and transrectal ultrasonography (TRUS) technology, that is, MRI-TRUS fusion as a new technology to guide prostate biopsy, can not only accurately locate by MRI, but also combine the real-time positioning of ultrasound, which can improve the accuracy of puncture. Reduce the misdiagnosis or missed diagnosis of prostate cancer due to imaging localization errors. [0003] During t...

Problems solved by technology

[0003] During detection, the probe is inserted into the human body. Due to discomfort or pain, the patient will move the position, resulting in a deviation from the initial preset position of the probe, but the detection system cannot get feedback on the displacement, resulting in errors and errors in image comparison. Inaccurate, affecting the test results. At the same time, the pressure of the probe on the gland cannot be kept constant, and it is easy to cause the deformation of the prostate to get an inaccurate image. Therefore, it is necessary to develop a new detection device that can effectively avoid the above defects.
