Embodiment 1
[0037] see Figure 1-Figure 9 , the present invention provides a device and method for mobilizing stem cells in a joint during operation, comprising a host 1, a brush head 2, and a charging base 3, the brush head 2 is connected to the top of the host 1, the host 1 and the brush head 2 are detachably connected, The host 1 can be connected to the charging base 3 for charging, and the operation is convenient.
[0038] The host 1 includes a sound wave motor 8, an output shaft 9 and a plurality of indicator lights. The sonic motor 8 is used to generate sonic vibrations of one or more frequencies. The sound waves are related to the frequency of motion of the sound wave motor 8 . In some embodiments, the sound waves are audible sound waves with a frequency of 20 Hz-20 kHz. In some embodiments, the sound wave is an ultrasonic wave with a frequency of 20 kHz to 1 GHz. The sound wave motor 8 is fixedly installed inside the host 1 and connected to the output shaft 9 . After receivin...
Embodiment 2
[0050] Taking the treatment of knee articular cartilage injury as an example, the specific implementation plan is as follows: After the arthroscopy enters the knee joint cavity, the structure of the suprapatellar pouch, the medial and lateral recesses of the knee joint, the medial and lateral meniscus, the cruciate ligament of the knee joint, cartilage, etc. Tissue structure, to clarify the degree and scope of cartilage damage, routine cleaning and freshening of the damaged cartilage area, and then use pyramid-shaped micro-fracture instruments to make micro-fractures of the subchondral bone in the cartilage defect area, forming multiple Connecting and bleeding microfracture holes. Finally, the device for mobilizing intra-articular stem cells during the operation is used to stimulate the synovial tissue in the joint cavity, including the synovial tissue of the suprapatellar bursa, inner and outer recesses of the knee joint. After the synovial tissue is stimulated by vibration, i...

[0052] Taking the treatment of knee articular cartilage injury as an example, the specific implementation plan is as follows: After the arthroscopy enters the knee joint cavity, the structure of the suprapatellar pouch, the medial and lateral recesses of the knee joint, the medial and lateral meniscus, the cruciate ligament of the knee joint, cartilage, etc. Tissue structure, to clarify the degree and scope of cartilage damage, routine cleaning and freshening of the damaged cartilage area, and then use pyramid-shaped micro-fracture instruments to make micro-fractures of the subchondral bone in the cartilage defect area, forming multiple Connecting and bleeding microfracture holes. Finally, a device that mobilizes intra-articular stem cells during the operation is used to stimulate the adipose tissue in the infrapatellar fat pad in the joint cavity. After the adipose tissue is stimulated by vibration, more adipose-derived stem cells can be released, thereby promoting the repair ...
