23 Jul Collector for obtaining sterile subpatellar fat pad under assistance of knee arthroscope
Abstract
The utility model relates to a collector for obtaining a sterile subpatellar fat pad under the assistance of a knee arthroscope. The device comprises a bottle body and is characterized in that the bottle body is composed of a left bottle and a right bottle, a filter screen is arranged between the left bottle and the right bottle, a secondary treatment connector is arranged at the bottom of the left bottle, a one-way valve is arranged in the left bottle, a piston push rod is arranged in a left chamber, the piston push rod is coaxial with the one-way valve, and the left bottle is provided with aplaner connecting end; and the right bottle is provided with a negative pressure suction end. Through a knee arthroscopy technology, a planing knife is utilized to directly crush and sterilely collect the self-suprapatellar fat pad visually. The method has the advantages that connective tissue and peripheral blood components are removed, homogeneous subpatellar adipose tissue is obtained, adiposevascular matrix components are separated out, and the obtained extract is enriched with various growth factors and adipose mesenchymal stem cells and has good safety and effectiveness. The device iseasy to operate, safe, effective and ingenious in design, and a convenient way is provided for application of adipose-derived stromal vascular components in the field of tissue engineering.
