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.
Claims24
A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow 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 seal with a surface of the hollow body;
- and
- at least two gaskets disposed in and 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 seal enabling the movable member to rotate about a longitudinal axis of the body.
A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow 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 integral with the member and placed on opposite sides thereof, the cover elements abutting on at least one annular step formed on a lateral outer surface of the body.
A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow 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 and rotatably mounted on the hollow body, and
- wherein the body has a part opposite to the distal opening with respect to the member for controlling or handling the body,
- wherein an innermost radius of the movable member matches an outermost radius of the elongate body to form a fluid-tight seal enabling the movable member to rotate about a longitudinal axis of the body.
A surgical device injecting bone cement in a bone cavity, comprising:
- an elongated, hollow body having an inner lumen with a distal opening to expel bone cement therefrom and a closed end opposite the distal opening;
- 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 and rotatably mounted on the hollow body, and
- wherein the body has a part opposite to the distal opening with respect to the member for controlling or handling the body,
- wherein an innermost radius of the movable member matches an outermost radius of the elongate body to form a fluid-tight seal enabling the movable member to rotate about a longitudinal axis of the body.
