Abstract: A cannula, handle and suction device to provide for the withdrawal of fluids from a body. A handle shaft has a receptacle connects to a cannula tapered bore leading to an end of a cannula shaft. The receptacle has a post that is conformingly received by the tapered bore such that an end of the post abuts the end of the cannula shaft. The cannula shaft has lubrication over its exterior. The handle shaft has an inner layer composed of a material that is destroyed when autoclaved, and a layer of lubricant covering an inner surface of the shaft. The handle shaft forms a chamber that may be sealed with a closure, and the chamber may opens into the channel such that the chamber acts as a Helmholtz resonator. The handle has a removable grip with a diameter of at least one inch and a circumferential flange.

Abstract: A clip having a compression surface and a clamping mechanism to compress an outer surface of a syringe barrel around a sealing portion. The clamping mechanism can comprise a rigid c-shape body, a flexible body that latches to clamp, or a flexible strap. The clip can alternatively clamp on to two flanges of a plunger, and have a protrusion that locks onto a syringe barrel flange.

Abstract: A cannula including a shaft an outer layer and an inner layer, the inner layer being composed of a material that will cause the inner layer to be destroyed when autoclaved. A pre-applied layer of lubricant covers the inner and outer surfaces of the shaft. A slide is slidingly received within the shaft. An adaptor on the cannula includes a fitting forming a tapered bore sized to allow an outer end of a receptacle post to compressively contact the end of the shaft. An elastic sealing device is configured to be compressed between the fitting and the receptacle when the receptacle post is received within the tapered bore. This sealing device further seals the connection, protecting the tissue from contamination.
