Separable instrument driver handle
An orthopaedic driver handle including a drivetrain having a driving end and a driven end opposite the driving end and defining a longitudinal axis, and a separable housing covering at least a portion of the drivetrain. The separable housing includes a first portion and a second portion separably connected to the first portion such that sliding the first portion relative to the second portion in a direction of the longitudinal axis unlocks the first portion from the second portion.
1. An orthopaedic driver handle, comprising:
a drivetrain having a driving end and a driven end opposite said driving end and defining a longitudinal axis; and
a separable housing covering at least a portion of said drivetrain, said separable housing including:
a first portion and a second portion separably connected to the first portion, wherein sliding said first portion relative to said second portion in a direction of the longitudinal axis unlocks said first portion from said second portion, wherein said first portion includes an interior surface with at least one groove formed adjacent a peripheral edge of said first portion and said second portion includes at least one tab adjacent a peripheral edge of said second portion, said at least one tab extending circumferentially, relative to the longitudinal axis, past said peripheral edge of said second portion, each of said at least one groove adapted to separably receive each of said at least one tab, wherein a bottom surface defines a bottom of said at least one groove and at least two ramped features are positioned on said bottom surface, said at least one tab includes at least one locking protrusion extending radially, relative to the longitudinal axis, therefrom, wherein said at least one locking protrusion fits within said at least one groove and slidably aligns with at least one of said at least two ramped features to prevent said first portion and said second portion from being pulled apart, said at least two ramped features are spaced from each other to allow insertion of each of the at least one locking protrusion between the two ramped features.
2. The orthopaedic driver handle according to claim 1 , wherein said first portion and said second portion each include an elongated region substantially parallel to the longitudinal axis and an angled region defining an angled axis relative to the longitudinal axis.
3. The orthopaedic driver handle according to claim 1 , further including a first locking member mated to an exterior of said separable housing and adapted to prohibit sliding of said first portion relative to said second portion in the direction of the longitudinal axis.
4. The orthopaedic driver handle according to claim 3 , wherein said first locking member is in the form of an annular collar.
5. The orthopaedic driver handle according to claim 3 , wherein said first locking member includes a second locking member adapted to prevent said first locking member from sliding off said exterior of said separable housing.
6. The orthopaedic driver handle according to claim 5 , wherein said second locking member is at least one of a spring-loaded element, a pin, a clasp, a thread and a fastener.
7. The orthopaedic driver handle according to claim 1 , wherein said separable housing further includes a gripping feature on an outer surface of the separable housing in the form of at least one of a plurality of scallops, a gripping texture and at least one abrasion.
