AI Technical Summary

Problems solved by technology

When the cutting portion is inside the patient, the user may not be able to determine the precise location of the cutting blade, and aligning the openings for aspiration and / or removal may be more difficult because the user may not be able to see where the openings are relative to each other
When there are more than two blades, it can become increasingly difficult for the user to align the openings of all the blades

Abstract

A micro debridement device (2), comprising: (a) a handpiece (4); (b) an interchangeable end (10) connected to the handpiece; (c) a rotatable an outer tube (16) connected to the interchangeable tip in a manner that includes an outer tube window (18); (d) an inner tube (12) extending at least partially through the outer tube, the The inner tube includes an inner tube window (14); (e) a locking selector (24) connected to the inner tube; and (f) a biasing device (26), wherein the biasing device is movable, and When the biasing means is moved into contact with the locking selector, the inner tube is immobilized so that the inner tube window is aligned with the outer tube window and with the wall of the outer tube Or in a state between the above two situations.

Description

technical field [0001] The present invention relates generally to a debridement blade comprising two or more blades, and more particularly to a device for positioning the window of one blade relative to the window of an adjacent blade. Background technique [0002] Typically, a debridement device includes a handpiece and a cutting section. The handpiece includes a motor that rotates one or more blades in the cutting section. The cutting portion includes a cutting window in the outer blade and which exposes the inner cutting blade. The cutting blade includes a sharp-edged window for performing surgical techniques such as removing tissue, cartilage, bone, or combinations thereof. Use of a cutting blade may result in bleeding, and the cutting blade may include an energy source to coagulate blood, ablate, or both. To use the cutting blade, the cutting blade is inserted into the patient, and once the procedure is complete, the cutting blade is removed from the patient. During...
