AI Technical Summary

Technical Problem

Current technologies lack precise, minimally invasive, and sustainable stimulation devices for the tibial periosteum, making it difficult to effectively utilize the periosteum's repair potential to address the vascular complications of diabetic foot.

Method used

A tibial periosteum implantable airbag stimulation device was designed, including a stimulation airbag, an air storage and driving component, and a power supply component. The device controls the periodic inflation and deflation of the airbag through a main control board. It utilizes elastic and biocompatible materials to achieve minimally invasive implantation and wireless charging, directly stimulating the tibial periosteum and activating angiogenesis potential.

Benefits of technology

It achieves precise, minimally invasive, and sustainable stimulation of the tibial periosteum, promotes lower limb vascular reconstruction, reduces the risk of trauma and recurrence, and improves patient compliance and convenience of life.

Abstract

The application belongs to the technical field of medical devices, and discloses a tibial periosteum embedded air bag stimulation device and method, which comprises a stimulation air bag, a gas storage and driving assembly and a power supply assembly. The stimulation air bag is implanted between the tibia and the periosteum, and the surface of the stimulation air bag is provided with ribs in the same direction as the long axis of the stimulation air bag. The stimulation air bag is respectively provided with an air inlet pipe and an air outlet pipe for air intake and exhaust. The gas storage and driving assembly comprises a gas storage bag and a gas pump. The gas storage bag is in communication with the air inlet pipe and the air outlet pipe. The air inlet pipe is connected in series with the gas pump and a first electromagnetic valve. The air outlet pipe is provided with a second electromagnetic valve. The power supply assembly, the gas pump, the first electromagnetic valve and the second electromagnetic valve are electrically connected with a main control board and are all packaged in a packaging assembly. The stimulation air bag is placed between the tibia and the periosteum to directly stimulate the inner layer of the periosteum rich in vascular endothelial progenitor cells and activate the potential of neovascularization through mechanical stimulation. The mechanical stimulation effect is enhanced through the convex ribs. The main control board is used for control without the intervention of the patient.
