Method and device for monitoring fracture rotation alignment in real time with assistance of gyroscope

Abstract

The invention belongs to the field of medical auxiliary equipment, which applies a medical spicule, a gyroscope real-time monitoring sensor and main control equipment. The method comprises the following steps that: firstly, a gyroscope suspended by the bone needle of the standard reference surface monitors the sensor in real time to obtain the space standard plane (cross section) required for measurement; then a medical bone needle is respectively placed at the relatively constant positions of the near end and the far end of the fracture; the absolute angle of each medical bone needle to thatground in the standard plane is measured by the gyroscope real-time monitor sensor; and a spatial relative rotation angle between the near end and the far end of the bone is calculated. The measuringsystem is concise in equipment, is easily operated by a single person, is low in manufacturing cost, is suitable for a narrow site, acquires real-time accurate data wirelessly, monitors the rotating alignment condition of the bone setting operation in an assisted mode in real time, requires no large medical equipment or professional teams, greatly saves the medical cost, also requires no X-ray fluoroscopy or CT scanning before or during the operation, causes no extra body injuries, and facilitates medical units of all levels to carry out the technology.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, and specifically relates to a method and a device for gyroscope-assisted real-time monitoring of fracture rotation alignment. Background technique [0002] Limb fractures caused by various reasons seriously affect patients' daily life and work ability, and endanger their health. Due to the increasing progress of medical technology and level, hospitals with relevant qualifications at home and abroad can carry out this kind of fracture surgery. [0003] Closed reduction and intramedullary nailing and osteosynthesis is one of the commonly used and standard minimally invasive treatment methods for this type of injury, because it can maximize the blood supply of the periosteum at the fracture end and promote fracture healing. However, the use of open surgery will aggravate the destruction of local blood supply, which is not conducive to fracture healing, and even leads to delayed bone heali...

AI Technical Summary

Problems solved by technology

However, this kind of method often needs to be equipped with specialized large-scale precision medical equipment and related software, requires a large operating room space, and is equipped with a tacit auxiliary team

Using this method will prolong the operation time, increase the chance of intraoperative blood loss and infection; additional fluoroscopy may cause physical harm to doctors and patients, and increase the medical expenses of patients. At the same time, it may be difficult for primary hospitals to popularize
