Abstract: A surgical device is provided which emulsifies body tissue, irrigates the surgical site with a saline solution, and removes fluids and tissue, via aspiration from the surgical site. More specifically, a surgical handpiece is provided which is particularly suited to be utilized for the removal of cataractous tissue from the eye. In order to prevent cross-contamination of tissue, the surgical device herein incorporates an easily detachable and disposable outer housing to facilitate thorough cleansing of the irrigation solution path and reduce the time and effort required for such cleaning. Moreover, a secure sealing system is provided in the area of the interface between the inner body portion of the handpiece and a stainless steel shell to prevent leakage and contamination of the irrigating solution.
