Embodiment Construction

[0033]The following embodiments show examples of flexible shaft surgical instruments that can be bent and locked to a desired angle by the user if desired. The disclosed embodiments of the flexible shaft surgical instrument can be repeatedly bent and rebent and locked into a variety of different positions without significant (adverse) plastic deformation of the flexible shaft surgical instrument in any of its bends. While the disclosed embodiments may specifically refer to repeatedly bendable surgical instruments such as razor blade surgical instruments (i.e., microdebriders), this example is provided merely to illustrate surgical instruments based on The repeatable bending configuration of the semi-rigid shaft portion of the oscillating shaft achieves certain advantages. It should be appreciated, however, that devices comprising semi-rigid tubes according to the present disclosure may find use in supporting any manner of surgical instrument where it is possible, for example, ...

Abstract

A flexible shaft surgical instrument having a compression member movable distally to provide a compressive force between the compression member and a distal compression bearing to compress a plurality of links and to be formed by those links The semi-rigid tube is rigidly locked in any of a number of user-selectable predetermined positions. The semi-rigid tube is configured to be flexed and locked in a user-selectable position and is returned to an unlocked state as the compression member is moved proximally without any noticeable movement of the semi-rigid tube. Plastic deformation.

Description

technical field [0001] The present disclosure relates to a surgical instrument having a flexible portion capable of being bent and locked into various orientations. Background technique [0002] Surgical instruments are known which have a thin elongated shaft to access the surgical site through natural or surgical openings in the body. These surgical instruments may be provided with a generally thin elongated shaft in a straight or curved configuration. [0003] Surgical instruments for scraping, cutting, cutting, scraping and / or removing tissue, bone and / or other body material are known. Such surgical instruments can include a cutting surface, such as a rotating blade, disposed on an elongated inner tube that rotates within an elongated outer tube having a cutting window. The inner and outer tubes together form a surgical cutting blade. Typically, the elongate outer tube includes a distal portion that defines an opening or cutting window that exposes the cutting surface ...
