Intelligent digital external fixed support for bone

Abstract

The invention belongs to the technical field of the surgical medical instrument, in particular relates to an intelligent digital external fixed support for bone, comprising a left support and a right support, characterized in that: both ends of the left support and the right support are respectively connected with fixed needles for fixing the bone, the left support and the right support are in the splicing sliding fit, the left support is provided with an intelligent controller and a pressure sensor. In the intelligent digital external fixed support for bone, the traditional rigid external fixed support is divided into the left support and the right support which are in splicing fit, a certain of scattering amount is formed between the left support and the right support, in the fracture treating process, the distance between two fractured bone fixed points is synchronously reduced by the stress stimulation, thus the stress shield can be eliminated, the fracture is cured rapidly, the intelligent controller and the pressure sensor arranged at the left support are used for collecting the stress information and transmitting the same to the external computer.

Description

technical field [0001] The invention belongs to the technical field of surgical medical instruments, and in particular relates to an intelligent digital external fixation bracket. Background technique [0002] The history of treatment of traumatic fractures can be traced back to before the appearance of human writing, and the treatment of fractures is closely related to the innovation and development of fixation devices. Before the 20th century, people have been using splints and plasters to treat fractures. Since the 20th century, with the maturity of surgical technology, scholars have begun to use various metal internal and external fixation devices to treat fractures. In recent decades, experts and scholars have continuously improved fractures. The installation method and material composition of the fixation equipment make the fracture healing conform to the natural law as much as possible. However, with the wide application of titanium alloy materials, the research on fi...

Problems solved by technology

It is clinically proven that controlled micro-movements at the fracture site, including longitudinal and lateral movements that do not exceed the tolerance of the repair tissue, can stimulate callus growth and increase its strength and stiffness, but fracture fixation using traditional rigid external fixators , it is impossible to accurately understand and control the fretting of the fracture end. If the fretting is too small, the fracture end will be shielded by stress and cannot be stimulated by stress, which will affect the fracture healing. If the fretting is too large, the fracture end will slow down and cause fracture displacement.

[0003] At present, external fixation brackets have been widely used clinically. After using external fixation brackets for fracture treatment, it is necessary to take X-ray films from time to time to understand the growth of fractures, so as to adjust the external fixation brackets. Because X-rays have radiation damage to the human body, it cannot be repeated in a short period of time. Therefore, the fracture monitoring is limited, and there is no medical device that can monitor the fracture healing in real time.
