Abstract
A scalpel handle sheath includes a body defining a handle-receiving cavity open to a first end of the body through a narrowed sleeve region, the body further defining a flexible arm adjacent the first end with a first boss extending inwardly therefrom adjacent the sleeve region. The sheath further includes a shield coupled with the body and slideable between a retracted position and a removal position. The shield defines an edge applying an inward force on the flexible arm during movement of the shield from toward the retracted position to the removal position and a removal flange extending within the shield and passing the first end of the body during movement of the shield from the toward retracted position to the removal position.
Core Innovation
The invention provides a scalpel handle sheath having a body defining a handle-receiving cavity open to a first end of the body through a narrowed sleeve region, and a flexible arm adjacent the first end with a first boss extending inwardly adjacent the sleeve region. The sheath includes a shield coupled with the body and slideable between a retracted position and a removal position, and the shield defines an edge applying an inward force on the flexible arm and a removal flange extending within the shield and passing the first end of the body.
In one configuration, the body further defines an arm region adjacent the first end with a first boss extending inwardly adjacent the sleeve region and a second boss extending outwardly from the arm. The shield is slideable between a retracted position and a removal position with an intermediate extended position therebetween, and the shield defines a clearance track receiving the second boss during sliding from the retracted position to the extended position.
A surgical device assembly is also provided, comprising a scalpel including a handle and a blade coupled with a holder end of the handle, and a sheath that removably receives the scalpel handle within the handle-receiving cavity. The shield applies an inward force on the second boss during movement from the extended position to the removal position to apply a bending moment to a portion of the blade, and the shield defines a removal flange extending within the shield and engaging with an end of the blade during movement from the extended position to the removal position.
Claims Coverage
The independent claims define three inventive features centered on a scalpel handle sheath, shield sliding positions, boss/arm force application, and removal-flange interaction.
Shield edge applying an inward force and removal flange passing the first end
A scalpel handle sheath with a body defining a handle-receiving cavity open to a first end through a narrowed sleeve region, and a flexible arm adjacent the first end with a first boss extending inwardly adjacent the sleeve region; and a shield coupled with the body and slideable between a retracted position and a removal position, where the shield defines an edge applying an inward force on the flexible arm and a removal flange extending within the shield and passing the first end of the body.
Clearance track applying inward force on the second boss with intermediate extended position
A scalpel handle sheath with a body defining a handle-receiving cavity open to a first side at an insertion opening and open to a first end through a narrowed sleeve region, and a flexible arm adjacent the first end with a first boss extending inwardly adjacent the sleeve region and a second boss extending outwardly from the arm; and a shield coupled with the body and slideable between a retracted position and a removal position with an intermediate extended position therebetween, where the shield defines a clearance track receiving the second boss during sliding from the retracted position to the extended position, an edge of the clearance track applying an inward force on the second boss during movement from the extended position to the removal position, and a removal flange extending within the shield and passing the first end of the body during movement from the extended position to the removal position.
Shield applying inward-force bending moment and removal flange engaging the blade
A surgical device assembly including a scalpel with a handle and a blade coupled with a holder end, and a sheath having a body defining a cavity open to a first end through a narrowed sleeve region with the scalpel handle removably received and the holder end extending through the sleeve region while the blade extends from the first end; the body defining a flexible arm adjacent the first end with a first boss extending inwardly adjacent a portion of the blade and a second boss extending outwardly from the arm; and a shield coupled with the body and slideable between a retracted position and a removal position with an intermediate extended position therebetween, where the shield applies an inward force on the second boss during movement from the extended position to the removal position to apply a bending moment to a portion of the blade, and defines a removal flange extending within the shield and engaging with an end of the blade during movement from the extended position to the removal position.
The independent claims collectively require a sheath with a slideable shield whose position relative to retracted, extended, and removal states determines how bosses on a flexible arm receive inward forces via shield-defined edges or clearance tracks and how a removal flange passes a first end and engages with an end of the blade.
