Arthroscopic cutting probe with active and return electrodes
A recently granted patent (Publication Number: US11883053B2) discloses an arthroscopic cutting probe designed for precision tissue resection during surgical procedures. The probe features an elongated shaft assembly with inner and outer metal sleeves, where the outer sleeve functions as an active electrode and the inner sleeve as a return electrode when coupled to an RF source. The probe includes a dielectric cutting member with a central passage for tissue resection, allowing the inner cutting window to rotate past the outer cutting window to cut tissue effectively. The design ensures precise cutting with minimal tissue damage, enhancing surgical outcomes.
Furthermore, the patent details an arthroscopic cutting system incorporating the cutting probe, a motor drive unit for rotation, an RF power supply, and a controller for operation. The system offers two modes of operation - mechanical tissue cutting and a combination of mechanical and electrosurgical cutting. Additionally, a negative pressure source is included to draw tissue through the cutting windows for efficient resection. The method outlined in the patent involves engaging the cutting member with tissue and rotating the inner cutting window past the outer window, providing a comprehensive solution for tissue resection in arthroscopic procedures. The innovative design and functionality of the cutting probe and system aim to improve surgical precision and patient outcomes in arthroscopic surgeries.
