Interskeletal pressure measurement system and method based on tension and pressure relation model

Abstract

The invention discloses an interskeletal pressure measurement system and method based on a tension and pressure relation model, and belongs to the technical field of interskeletal pressure measurement. The technical problem to be solved is to provide an interbone pressure measurement system hardware structure based on a tension and pressure relation model and an improvement of a measurement method. According to the technical scheme, the static strain testing device is included, a display screen and a state indicating lamp are arranged on the front face of a shell of the static strain testing device, a central controller and an AD conversion module are packaged in the shell, and the signal output end of the AD conversion module is connected with the central controller through a wire; the central controller is further connected with the display screen, the state indicating lamp, the data storage module and the data communication module through wires. The data communication module is also connected with the measuring computer through a communication lead; the signal input end of the AD conversion module is connected with the signal output ends of the tension sensor and the pressure sensor through wires. The invention is applied to the measurement of interosseous pressure.

Description

technical field [0001] The invention discloses an interosseous pressure measurement system and method based on a tension-pressure relationship model, belonging to the technical field of interosseous pressure measurement. Background technique [0002] Bone is the hardest tissue in the human body. It mainly supports the body, protects internal organs, and participates in metabolism. It is also a part of the human body movement system. The human body cannot perform all normal actions without the support of bones. Therefore, the health of human bones The degree of bone is important for normal movement; and one of the indicators that usually judges the health of bones is the normal healing between bones and the ability of the body to adjust the pressure between bones through adaptive control. [0003] In recent years, more and more researches have been carried out on the detection methods of interosseous pressure. The research mainly focuses on the two aspects of external fixatio...

Problems solved by technology

[0003] In recent years, more and more researches have been carried out on the detection methods of interosseous pressure. The research mainly focuses on the two aspects of external fixation and embedded detection technology. In these studies, the real application of pressure detection in bone joint surgery There are few technical researches, or the detection methods are relatively traditional; the detection of interosseous pressure is very important, and the accuracy of bone pressure detection will affect the success rate of bone surgery and the postoperative recovery speed of patients, and in the clinical treatment of bone surgery In general, because the interosseous pressure is affected by the size of the bone gap and other characteristics, it is difficult to measure the interosseous pressure. The measurement method is basically based on the doctor's experience or rough pressure estimation, measuring the size of the bone gap and quantifying the interosseous pressure. The technology of pressure is basically blank, so it is necessary to propose a device and method for measuring interosseous pressure
