Surgical device with flexible inner shaft and cutting element
A recently granted patent (Publication Number: US11918246B2) discloses a novel surgical device designed to enhance precision and flexibility during surgical procedures. The device comprises an elongated outer shaft and an inner shaft with a flexible portion that is more flexible than the rest of the shaft. A cutting element at the distal end of the inner shaft moves within the outer shaft, which exposes the cutting element during operation. The device features a series of bearings strategically placed between the inner and outer shafts to maintain the alignment of the flexible inner shaft portion with the outer shaft as the device is in use. These bearings include proximal, distal, and intermediate bearings with varying thicknesses to optimize performance.
Furthermore, the patent details a method for operating the surgical device, emphasizing the controlled movement of the inner shaft to manipulate the cutting element accurately. The actuator at the proximal end of the inner shaft enables different types of movements, such as single-direction rotation, oscillating rotation, or reciprocating translation along the central axis. The device's design allows for even or uneven spacing of the bearings along the flexible inner shaft portion, with options for bearings with annular cross-sections and cut-aways for enhanced functionality. Overall, the patented surgical device aims to improve surgical outcomes by providing surgeons with a tool that offers both precision and flexibility in various procedures.
