Abstract
A surgical tool handle and separate disposable orthopedic tool head assembly is disclosed. The surgical tool handle has a reinforcing member extending from it. The reinforcing member is receivable in an internal bore of the disposable orthopedic tool head and provides structural reinforcement for the tool head. This reinforcement allows the use of disposable materials in the construction of the tool head that otherwise could not be use (e.g., plastic and resin materials) because of an increased risk of breakage or failure relative to metallic tool heads.
Claims22
A surgical tool handle, which comprises:
- a) a surgical tool handle;
- b) a reinforcing member comprising a first length extending from a distal reinforcing member portion having a distal end to a spaced apart proximal reinforcing member portion connectable to the tool handle;
- and
- c) a locking mechanism comprising a locking pawl having a second length extending from a distal locking pawl portion to a proximal locking pawl portion pivotably attached to the tool handle, wherein the locking pawl is pivotable between a locked position with the distal locking pawl portion seatable in a catch of a surgical tool head secured to the tool handle with the reinforcing member received in an internal bore of the tool head, and an unlocked position with the distal locking pawl portion free of the tool head catch;
- and
- d) wherein in the locked position, the distal locking pawl portion seatable in a catch of a surgical tool head is spaced from the tool handle by a first distance that is less than a second distance measured from the distal end of the reinforcing member to the tool handle.

A surgical tool handle, which comprises:
- a) a surgical tool handle;
- b) a reinforcing member comprising a first length extending from a distal reinforcing member portion having a distal end to a spaced apart proximal reinforcing member end integral with the tool handle;
- c) a locking mechanism comprising a locking pawl having a second length extending from a distal locking pawl portion to a proximal locking pawl portion pivotably connected to the tool handle, wherein the locking pawl is pivotable between a locked position with the distal locking pawl portion seatable in a catch of a surgical tool head secured to the tool handle with the reinforcing member received in an internal bore of the tool head, and an unlocked position with the distal locking pawl portion free of the tool head catch;
- and
- d) wherein in the locked position, the distal locking pawl portion seatable in a catch of a surgical tool head is spaced from the tool handle by a first distance that is less than a second distance measured from the distal end of the reinforcing member to the tool handle.

A surgical tool handle, which comprises:
- a) a surgical tool handle;
- b) a reinforcing member comprising a first length extending from a distal reinforcing member portion having a distal end to a spaced apart proximal reinforcing member end connected to the tool handle;
- c) a locking mechanism comprising a locking pawl having a second length extending from a distal locking pawl distal portion to a proximal locking pawl portion connected to the tool handle, wherein the locking pawl is movable between a locked position with the distal locking pawl portion seatable in a catch of a surgical tool head secured to the tool handle with the reinforcing member received in an internal bore of the tool head, and an unlocked position with the distal locking pawl portion free of the tool head catch;
- and
- d) wherein in the locked position, the distal locking pawl portion seatable in a catch of a surgical tool head is spaced from the tool handle by a first distance that is less than a second distance measured from the distal end of the reinforcing member to the tool handle.
2 more elements
A surgical tool handle, which comprises:
- a) a surgical tool handle;
- b) a reinforcing member comprising an outer surface having a first length extending from a distal reinforcing member portion including a distal end to a spaced apart proximal reinforcing member portion connected to the tool handle, wherein at least a portion of the outer surface is threaded;
- c) a locking mechanism comprising a locking pawl having a distal locking pawl portion extending to a proximal locking pawl portion pivotably attached to the tool handle, wherein the locking pawl is pivotable between a locked position with the distal locking pawl portion seatable in a catch of a surgical tool head secured to the tool handle with the reinforcing member received in an internal bore of the tool head and an unlocked position with the distal locking pawl portion free of the tool head catch;
- and
- d) wherein the threaded outer surface of the reinforcing member is adapted to threadingly engage the internal bore of a surgical tool head when the reinforcing member is fully received in the internal bore.
