A surgical instrument including an articulating region. An outer tube and an inner tube are axially fixed to one another distal to the articulating region and axially movable relative to one another proximal to the articulating region. Relative movement of the inner and outer tubes provides for articulation of the articulating tube assembly to a curved configuration. A working tool may be removably directed through a central cannula defined by the inner tube. The working tool may include a shaft having a flexible region configured to be arranged within the articulating region. The shaft may rotate within the inner tube with the articulating tube assembly in the curved configuration. The working tool may include a housing hub configured to be coupled with a handle to removably position the flexible region within the articulating region. Multiple working tools may be interchangeably directed through the central cannula.

Surgical instrument with articulating region

Surgical tool systems and methods of use thereof for performing endoscopic surgical procedures, which systems include a handpiece and a surgical accessory which detachably connects to the handpiece. The surgical accessory has a distal end which defines a cutting head incorporating two different types of tissue-treating areas.

Surgical tool systems, and methods of use thereof

A surgical tool arrangement for performing endoscopic surgical procedures which includes a powered handpiece and a surgical cutting accessory which detachably connects to the handpiece. The cutting accessory incorporates a cutting head for resecting tissue and a suction arrangement at the distal end of the cutting accessory closely adjacent the cutting head which suction arrangement serves to evacuate tissue from the surgical site and additionally serves as a cleaning mechanism for the surgical cutting accessory. The accessory additionally incorporates a bearing arrangement for supporting the cutting element as same rotates within the housing element.

Surgical tool arrangement and surgical cutting accessory for use therewith

A surgical instrument () includes an articulating tube assembly () having a proximal end and a distal end, an articulating region () disposed between the proximal end and the distal end, and a proximal axis axially extending from the proximal end to the articulating region (). The articulating tube assembly () includes an inner tube () and an outer tube () each having the articulating region (). The inner tube () and the outer tube () being movable relative to each other proximal to the articulating region () and fixed axially relative one another distal to the articulating region (). The surgical instrument () also includes an actuation assembly () coupled to the articulating tube assembly () for moving the inner tube () and the outer tube () axially relative to each other for articulating the articulating region () of the articulating tube assembly () between a first configuration and a second configuration, wherein the articulating region () is rigid in the first configuration and the second configuration.

Surgical instrument with articulation region

A surgical tool arrangement for performing endoscopic surgical procedures which includes a powered handpiece and a cutting accessory which detachably connects to the handpiece. The cutting accessory has a distal end which defines a cutting head incorporating a suction arrangement directly adjacent the cutting features thereof.
