Abstract

An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion/bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

Claims

1. An osteotome comprising:

a body, said body comprising;

a support portion;

a tip portion, said tip portion extending from a first end of said support portion and terminating in a free end;

said tip portion comprising a first conduit configured to begin proximate to said free end of said tip portion and to extend into said support portion;

said first conduit configured to terminate at said free end of said tip portion in an opening;

said tip portion comprising means for interchangeably securing any one of a plurality of tip members to said tip portion; and

a hydration port, said hydration portion comprising a hydration conduit, said hydration conduit configured to be in fluid communication with said first conduit, and said hydration port configured to releasably couple a hose thereto, for the hose to be in fluid communication with said hydration conduit;

a first tip member having a first end and a second end, said first tip member comprising an orifice beginning at said second end of said first tip member and extending a portion of the way to said first end of said first tip member;

said first tip member comprising a tip conduit configured to be in fluid communication with said orifice, and configured to terminate in an opening at said first end of said first tip member;

said first tip member further comprising a plurality of radial conduits, each in fluid communication with said tip conduit, and configured to terminate at respective side openings at a side surface of said first tip member, in proximity to said first end of said first tip member;

an axis of each of said plurality of radial conduits a configured to radiate from the same point of origin, to be generally coplanar;

wherein said orifice of said first tip member is configured to releasably receive said tip portion of said body therein, to releasably mount said first tip member to said body with said means for interchangeably securing; and

a handle portion.

2. The osteotome according to claim 1 wherein said tip member further comprises a seal means, said seal means configured to for releasably sealing said tip member with respect to said tip portion.

3. The osteotome according to claim 1 wherein said first end of said tip member comprises a conical surface.

4. The osteotome according to claim 1 further comprising a syringe and a hose, said, syringe comprising a barrel with graduated markings thereon, and a plunger slidably disposed within said barrel;

a first end of said hose being coupled to an outlet opening of said barrel, and a second end of said hose being coupled to said hydration port, for said barrel of said syringe to be in fluid communication with said orifice of said tip member.

5. The osteotome according to claim 1 wherein said side surface of said tip member comprises a cylindrical surface;

and where said plurality of radial conduits are equally spaced radially.

6. The osteotome according to claim 1 wherein said opening proximate to said first end of said tip member comprises an opening selected from the group of openings consisting of:

a single, centered circular opening on said first end of said tip member;

a plurality of circular openings on said first end of said tip member;

a cruciform shaped opening on said first end of said tip member; and

a hexaform-shaped opening on said first end of said tip member.
