Abstract
Abstract The instrument has a straight line shaft which is provided with a calibrated cylindrical hook at one end and a pistol grip at the opposite end. The hook is sized to engage in an eye on a shaft of a prosthesis with a snug fit and is set perpendicularly to the instrument shaft. A hammering element is also slidably mounted on the instrument shaft to impact against an anvil on the hook.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
An assembly comprising a joint head prosthesis having a shaft, a projection extending from said shaft and a calibrated cylindrical eye within said projection; and an implanting instrument connected to said eye, said instrument for implanting said prosthesis in a bone comprising an elongated rod having a longitudinal axis, a handle mounted on said rod at one end thereof, said handle being disposed in a plane containing said axis of said rod and extending perpendicularly from said rod, and a hook mounted on the opposite end of said rod, said hook having an axis perpendicular to said plane of said handle and said axis of said rod and being of cylindrical shape calibrated to fit with a snug fit into said calibrated cylindrical eye in said prosthesis to form a rigid connection between said prosthesis and said instrument for turning about said longitudinal axis of said instrument while simultaneously allowing free rotation of said instrument relative to said prosthesis about said axis of said hook.
Claim 2
Dependent Claim
165 words
An assembly comprising a joint head prosthesis having a shaft, a projection extending from said shaft and a calibrated cylindrical eye within said projection; and an implanting instrument connected to said eye, said instrument for implanting said prosthesis in a bone comprising an elongated rod having a longitudinal axis, a handle mounted on said rod at one end thereof, said handle being disposed in a plane containing said axis of said rod and extending perpendicularly from said rod, and a hook mounted on the opposite end of said rod, said hook having an axis perpendicular to said plane of said handle and said axis of said rod and being of cylindrical shape calibrated to fit with a snug fit into said calibrated cylindrical eye in said prosthesis to form a rigid connection between said prosthesis and said instrument for turning about said longitudinal axis of said instrument while simultaneously allowing free rotation of said instrument relative to said prosthesis about said axis of said hook.
Claim 3
Dependent Claim
47 words
An assembly as set forth in claim 1 wherein said hook is integrally formed on a one piece hook element further having an anvil surface at the rear thereof, and which further comprises a hammering element slidably mounted on said rod for hammering against said anvil surface.
