Abstract
A surgical device and method for injecting cement in a bone cavity includes an elongated, hollow body to be inserted partially into the cavity. The body has an inner lumen with a distal opening to expel cement therefrom. An entry plug for the cement is connected to a cement pressurized supply. The entry plug is in fluid communication with the lumen to deliver cement through the entry plug, wherein the entry plug is movably mounted on the hollow body.
Claims20
A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow body to be inserted partially into the bone cavity;
- the body having an inner lumen with a distal opening to expel bone cement therefrom;
- a member having access to the cement from a bone cement pressurized supply, the member being in fluid communication with the lumen to deliver bone cement through the hollow body, wherein the member is movably mounted on the hollow body;
- and
- further comprising two cover elements coaxially applied to the member and fixed thereto on opposite sides, the cover elements abutting on annular steps formed on a lateral outer surface of the body so as to enclose and constrain the member between them.

A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow body to be inserted partially into the bone cavity, the body having an inner lumen with a distal opening to expel bone cement therefrom, and including a thicker region having at least two recessed seats;
- a movable member having access to the bone cement from a bone cement pressurized supply, the movable member being in fluid communication with the lumen to deliver bone cement through the hollow body, wherein the movable member is rotatably mounted to and forms a fluid-tight slidable seal with a surface of the hollow body;
- and
- at least two gaskets disposed in and completely filling the recessed seats of the thicker region, wherein an innermost radius of the movable member matches an outermost radius of the elongate body to form the fluid-tight slidable seal enabling the movable member to rotate about a longitudinal axis of the body and to slide along said longitudinal axis.
