US 10,207,045 B2 · Surgical handpiece with disposable concentric lumen work tip

Abstract

A surgical handpiece has a connecting body with a distal end and a work tip with a hub at a proximal end. The hub is detachably connected to the connecting body by a threaded connector. The work tip has an open operating end at a distal end. This opening leads an axial channel extending through the work tip from the operating end to the hub. A radial channel extends from the axial channel in the hub to the external surface of the hub. A sleeve surrounds and is spaced from the hub. This sleeve extends to the vicinity of the operating end of the work tip, and has a first external connector in the region of the radial channel of the hub. The sleeve also has a second external connector. A seal is provided for establishing a fluid connection between the radial channel of the hub and the second external connector of the sleeve. The first external connector of the sleeve is in fluid connection with an irrigation channel between the inner surface of the sleeve and the external surface of the work tip. This irrigation channel extends to the vicinity of the operating end of the work tip for delivery of irrigation fluid to that area. The irrigation channel is generally concentric with the axial channel in the hub. Aspiration fluid is withdrawn from the open operating end of the work tip, through the axial and radial channels of the hub, the seal and the second external connector of the sleeve to an aspiration pump.

A surgical handpiece comprising:

a connecting body having a distal end;
a work tip having an open operating end at a distal end thereof and an axial channel extending there through;
a hub connected to a proximal end of the work tip, said hub having a threaded connector for detachably attaching the hub to the connecting body, a hub axial channel formed by the hub and connected to the work tip axial channel at the proximal end of the work tip and a radial channel formed by the hub and extending at an angle from the hub axial channel to an external surface of the hub;
a sleeve surrounding and spaced from the hub, said sleeve extending to the vicinity of the open operating end of the work tip, said sleeve having a first external connector;
a second external connector connected to the radial channel of the hub;
and
a seal for establishing fluid connection between the radial channel of the hub and the second external connector;
and
wherein the first external connector of the sleeve is in fluid connection with an irrigation channel between an inner surface of the sleeve and the external surface of the work tip which extends to the vicinity of the open operating end of the work tip for delivery of irrigation fluid to that vicinity of the open operating end of the work tip, said irrigation channel being generally concentric with the axial channel in the hub;
and
wherein aspiration fluid is withdrawn from the open operating end, through the hub axial channel, the radial channel of the hub, the seal and the second external connector.
