Abstract
A surgical handpiece nosecone having an end overmold portion and/or an internal overmold portion. The end overmold portion is located at an end of the nosecone and compressed between the surgical handpiece housing and nosecone. The internal overmold portion is positioned radially about the nosecone on the inner surface to provide a fluid tight seal that prevents ingress of irrigation fluid into the housing.
Claims20
A method for attaching members of a medical device, comprising:
- providing a first member having a first body and a first connecting section, the first connecting section having a first end face, an inner surface, a nub on the inner surface extending radially inward, and an end overmold portion at least partially covering the first end face;
- providing a second member having a second body, a second connecting section and a shoulder at the junction between the second body and the second connecting section, the second connecting section having a second end face and an outer surface, the outer surface having a groove extending from the second end face towards the shoulder;
- telescoping the second connecting section into the first connecting section;
- locating the groove in the outer surface of the second connecting section;
- positioning the nub to engage the groove and moving the nub in the groove towards the shoulder until the end overmold portion contacts the shoulder whereby the end overmold portion is compressed between the first body and the second body.
An ultrasonic aspirator apparatus for fragmenting tissue and removing fragmented tissue, comprising:
- a surgical handpiece comprising a housing, a nosecone attached to the housing, and a transducer mounted within the housing;
- a surgical tip connected to the transducer;
- an irrigation system connected to the handpiece for supplying irrigation fluid adjacent the surgical site for suspending fragmented tissue;
- and
- an aspirating system connected to the handpiece for aspirating fluid and tissue fragmented at the surgical site;
- wherein the nosecone has an inner surface and an outer surface, and has an internal overmold portion on the inner surface positioned radially about the nosecone to provide a fluid tight seal that prevents ingress of irrigation fluid into the housing.
An ultrasonic aspirator apparatus for fragmenting tissue and removing fragmented tissue, comprising:
- a surgical handpiece comprising a housing, a nosecone attached to the housing, and a transducer mounted within the housing, and wherein the nosecone includes an end overmold portion in contact with the housing to provide a seal between the housing and the nosecone;
- a surgical tip connected to the transducer;
- an irrigation system connected to the handpiece for supplying irrigation fluid adjacent the surgical site for suspending fragmented tissue;
- and
- an aspirating system connected to the handpiece for aspirating fluid and tissue fragmented at the surgical site.
