Description
Technical field
The invention belongs to the surgical medical equipment technical field, be specifically related to a kind of intelligent digital external fixed support for bone.
Background technology
The treatment history of trauma fracture can be traced back to before the appearance of mankind's word, and the treatment of fracture and the innovation and development of fixation device are closely related.Before 20th century, people use clamping plate always, Gypsum Fibrosum is treated fracture, 20th century began the maturation along with surgical technic, scholars bring into use various metal inside and outside fixation devices to treat fracture, mounting means and material that nearly decades, experts and scholars updated the fracture fixation equipment form, make union of fracture meet the natural law as far as possible, but the extensive use along with titanium alloy material, the research of fixation device has entered a plateau, and carrying out of less invasive techniques also makes the fractures technology of simulating nature growth enter plateau.Clinical proof, fracture site has the fine motion of control, comprise vertically reaching the lateral movement that does not surpass the toleration of repair tissue, can stimulate growth of spur, increase its strength and stiffness, but use traditional rigid body exterior fixation bracket to carry out fracture fixation, can't accurately understand and control the fine motion of fracture end, the too small fracture site that causes of fine motion is subjected to stress shielding, can not get stress stimulation, affect union of fracture, fine motion is excessive can be made again the fracture end slow concrescence and produce displacement fracture.
The clinical extensive use of external fixed support for bone at present, fractures needs irregularly to take x line sheet after with exterior fixation bracket and understands the fracture growing state, thereby adjustment exterior fixation bracket, because X ray has radiation injury to human body, can't repeatedly take in a short time, so the fracture situation monitoring is restricted larger, also there is no the medical apparatus and instruments of energy Real-Time Monitoring union of fracture situation.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of intelligent digital external fixed support for bone, understand the union of fracture situation and study the needed optimum stress of fracture end with this by real-time detected pressures.
Described intelligent digital external fixed support for bone, comprise left stretcher body, right stretcher body, it is characterized in that described left stretcher body, right stretcher body two ends connect respectively the locking pin that is provided for fixing bone, left stretcher body and right stretcher body are pegged graft and are slidably matched, and are equipped with intelligent controller and pressure transducer on left stretcher body.
