Embodiment Construction

[0023] figure 1 and figure 2 An ultrasonic surgical assembly 20 is shown that may be used by a user, such as a surgeon, to remove / cut biological material from a patient. Ultrasonic surgical assembly 20 includes an ultrasonic instrument 22 having a proximal end 24 , a distal end 26 and an aspiration channel 28 . The ultrasonic instrument 22 includes a housing 30 having a proximal portion 32 and a distal portion 34, a transducer 36 disposed at least partially within the housing 30 (see figure 2 ), a horn 38 coupled to a transducer 36, and an ultrasonic tip 40 for removing / cutting biological material from a patient.

[0024] refer to figure 2 , the transducer 36 is at least partially disposed within the housing 30 . Transducer 36 may include one or more piezoelectric elements, magnetostrictive elements, or other suitable elements configured to generate mechanical energy to be provided to horn 38 and ultimately transmitted through ultrasonic tip 40 to the surgical site.

Abstract

An ultrasonic surgical instrument assembly including an irrigation sleeve assembly defining a lumen and an ultrasonic tip at least partially disposed within the lumen of the irrigation sleeve. The irrigation sleeve assembly may comprise a hub and an irrigation sleeve coupled to the hub. The irrigation sleeve may comprise an inner sheath and an outer sheath, both extending distally from the hub. The outer sheath may surround at least a portion of the inner sheath to define an irrigation passageway between the outer sheath and the inner sheath configured to deliver irrigation fluid to the surgical site. The distal end of the inner sheath may extend beyond the distal end of the outer sheath. Each of the inner and the outer sheath may be coupled to the hub by an annular sealing member configured to create fluid-tight seal between the hub and the respective inner and outer sheath.

Description

Background technique [0001] When ultrasonic instruments are used to cut tissue, the buildup of heat and biological debris can lead to various adverse effects, such as damage to the ultrasonic instrument and / or surrounding tissue, and reduced visibility. To eliminate or reduce these unwanted effects, irrigation and suction systems can be used in conjunction with ultrasonic instruments. Irrigation and aspiration systems typically involve delivering irrigation fluid to the surgical site along the ultrasonic instruments to irrigate the surgical site and cool the ultrasonic instruments. A suction source can aspirate excess fluid and biological debris from the surgical site to provide better visualization. [0002] Existing ultrasonic instruments may utilize a series of cannulas arranged over the ultrasonic tip of the ultrasonic instrument to guide irrigation fluid and a central aspiration channel for suction. However, such ultrasonic instruments may be difficult to maneuver into ...
