The embodiment of the invention provides a pelvis parameter measurement method, device and system, a storage medium and a program product, and relates to the technical field of medical image processing. The method comprises the steps of segmenting three-dimensional image data of a pelvis, extracting sacrum information and femoral head information, determining a hip axis midpoint based on the femoral head information, constructing a pelvis coordinate system based on the sacrum information, the femoral head information and the hip axis midpoint, and calculating posture parameters of the pelvis in the pelvis coordinate system based on the sacrum information and the femoral head information. According to the embodiment of the invention, by segmenting the three-dimensional image data, the anatomical structure information such as sacrum and femoral head information is accurately extracted, and then the pelvic parameters are calculated on the pelvic coordinate system constructed based on the anatomical structure information, so that the obtained pelvic attitude parameters can more accurately reflect the real attitude of the pelvic, and the accuracy of the pelvic attitude is improved. And the accuracy and reliability of pelvis attitude parameter analysis are improved.

The invention relates to the technical field of medical instruments, in particular to a detachable folding type intelligent spine traction repositor which comprises a traction mechanism and an intelligent traction controller, a lumbosacral support, a chest support and a cervical vertebra support are sequentially arranged in the middle of a main cushion body along the middle line of the main cushion body, and a main traction air pressure sensor is installed in a detection cavity; each bearing pad body is provided with an electromyogram sensor and two pressure sensors; a traction system is carried in the traction intelligent controller, the main traction subsystem comprises a traction module, a traction force detection module and a human body state detection module, and the directional traction subsystem comprises a directional traction module; by arranging the traction mechanism and the traction intelligent controller, precise directional traction is synchronously carried out while regional traction is carried out, traction correction is carried out on the side protrusion position, the treatment effect on a patient is improved, intelligent traction correction of spine traction is achieved, and the purpose of safe traction is achieved.

An embodiment of the present invention provides a system for incising the anus and cutting the sacrum of a carcass, and a working method using same, the system comprising: a position sensor unit comprising a plurality of positioning sensors for detecting a moving position of a carcass moving along a main conveyor while hung on a hanger; an image processing unit that photographs the carcass moving along the main conveyor and calculates image information of the carcass; a tool module unit for automatically performing anal incision and sacrum cutting operations on the carcass hung on the hanger; and a main control unit for providing work operation information to the tool module unit on the basis of the image information of the carcass calculated by the image processing unit, wherein the main control unit is configured to control the operations of the image processing unit and the tool module unit according to the moving position of the carcass measured by the position detection sensor.

This invention provides a method and system for monitoring fetal head descent. The method includes: deploying a magnetic field transmitter to the abdomen of the mother and a back sensor to the sacrum and coccyx; using measurement sensors to perform external and internal measurements on the mother to obtain measurement data of the anterior superior iliac spine and mid-pelvis; using an ultrasound probe to perform a longitudinal section on the perineum to obtain the maximum cross-section of the pubic symphysis and to acquire the position of the lower edge of the pubic symphysis and the position of the lowest point of the fetal head; standardizing the coordinates of the lower edge of the pubic symphysis and the position of the lowest point of the fetal head; and obtaining the numerical value and direction of the presenting part of the fetus based on the standardized coordinates of the lower edge of the pubic symphysis, the standardized coordinates of the lowest point of the fetal head, the measurement data of the anterior superior iliac spine, and the mid-pelvis, thus obtaining fetal head descent monitoring data. This invention can analyze the fetal head according to the actual situation of the mother, eliminating the need for manual digital examination, reducing errors caused by individual differences among mothers, and improving the accuracy of fetal head descent monitoring.
