US Patent 11622784 Arthroscopic devices and methods

Arthroscopic cutters are used for resecting tissues, such as meniscal tissues, in meniscectomies or other arthroscopic procedures. The arthroscopic cutters have a shaft assembly with openable-closeable jaws at a working end of the shaft. A handpiece having a motor drive may be detachably coupled to a hub on a hub end of the handpiece. When the shaft is coupled to the handpiece, the motor drive will couple to the jaw structure to open and close the jaw structure to cut meniscal and other tissues.
