Pelvis measuring and calculating device and method

Abstract

The invention discloses a pelvis measuring and calculating device. The device is characterized by comprising: an ultrasonic imaging unit which comprises an ultrasonic host module and an ultrasonic probe; a positioning unit which comprises a positioning host module and a first positioning sensor, wherein the first positioning sensor is fixed on the ultrasonic probe and records the position information of the ultrasonic probe; and a data processing unit which is used for calculating the distance between a first pelvic feature point and a second pelvic feature point according to the two-dimensional coordinates of the first pelvic feature point and the second pelvic feature point in a pelvic ultrasonic image and the position information of the ultrasonic probe. The invention also provides a pelvis measuring and calculating method. Compared with conventional pelvic external measurement technologies in obstetrics clinic at present, the pelvic measuring and calculating device and method provided by the invention can eliminate the measurement error caused by fat thickness, reduce the infection risk caused by finger examination, and have deeper understanding on the pelvic meridian and pelvic shape.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pelvic measuring device and a method thereof. Background technique [0002] In obstetrics, whether the bone birth canal is narrow or not is of great significance to whether the fetus can be delivered smoothly. If the pelvic stenosis is not detected before delivery and corresponding treatment measures are not taken, it will cause serious maternal and child complications, such as fetal distress or death, intracranial hemorrhage, urinary fistula or fecal fistula in pregnant women, and increased incidence of puerperal infection. Therefore, accurate prenatal measurement of pelvic diameter is of great significance. [0003] There are many ways to measure the pelvis, the most accurate is X-ray measurement. However, due to the greater impact of X-rays on the fetus, it is rarely used clinically. As a new diagnostic tool, CT is simple in operation, accurate in results, and the fetal r...

Problems solved by technology

[0004] However, simply using ultrasound to measure the pelvic meridian can only measure the distance between two pelvic feature points on the same ultrasound plane. If the two feature points of the pelvis cannot be displayed on the same ultrasound plane, this method is no longer applicable

Therefore, current methods of measuring the pelvic meridian using ultrasound are limited in clinical application
