Adjustable self-stress stimulation bone fracture plate

Abstract

The invention discloses an adjustable self-stress stimulation bone fracture plate which comprises a plate body A and a plate body B; the plate body A and the plate body B are in butt joint through anelastic piece. According to the adjustable self-stress stimulation bone fracture plate, length adjustment and axial stress accurate adjustment and control of the adjustable self-stress stimulation bone fracture plate can be achieved, and axial stress stimulation can also be provided under the condition that a patient is in a horizontal position or has no load, so that bone growth is facilitated, and early rehabilitation of the patient is promoted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable self-stress stimulating bone plate. Background technique [0002] Stress stimulation, growth and development of human bone tissue and bone disease rehabilitation process are constantly being shaped and rebuilt to adapt to the surrounding environment. Only when the bone continuously adapts to the mechanical environment that bears the stress stimulation generated by the external force, can the bone structure itself be remodeled and shaped to adapt to changes in the external environment. [0003] The stress adaptability of the bone is also called the functional adaptability of the bone. Specifically, when the bone needs increase, there is bone formation to increase their ability to perform their functions; when the need decreases, there is bone resorption, which reduces their ability to perform their functions. , it can be seen that changes such as bone growth, developm...

AI Technical Summary

Problems solved by technology

"Compressed microdeformation" cannot occur when the patient lies on his back or sleeps in bed, and the average sleep time of an adult may be about 8 hours. After the operation, the patient may stay in bed for 15 hours or more due to reasons such as inability to bear weight for a long time and pain. , which is not conducive to bone healing and rapid recovery of patients, so the patient has a long time in bed after surgery and lacks stress stimulation. The implant design needs to be improved

[0010] At present, the adjustable self-stress stimulation bone plate with elastic steel plate is compressed under the action of gravity, but cannot produce "cohesive" tension, and the stress stimulation will fail in the supine position
