Abstract:
A self-locking retractable surgical knife including a sheath member having front and rear ends, and a retractable member including a support member and a blade supported by the support member. The support member has a front end, a rear end and an elongated interior space. The retractable member is partially disposed in the sheath member and telescopically received in the sheath member for movement between a guarded position wherein the blade is guarded in the sheath member, and an exposed position wherein the blade extends out of the sheath member. The self-locking retractable further includes a biasing member disposed in the interior space of the support member and a latch member disposed in the interior space of the support member.

Claim (Index 7):
A retractable tool holder, comprising:\n a sheath member having front and rear ends; a retractable member including a support member and a tool head retention element supported by the support member, wherein the support member having an elongated interior space; the retractable member being partially disposed in the sheath member, and telescopically received in the sheath member for movement between a guarded position wherein the tool head retention element is retracted into the sheath member, and an exposed position wherein the tool head retention element extends out of the sheath member; top and bottom elongated and longitudinally extended slots formed on the support member wherein the top slot is disposed along a top side of the support member and the bottom slot is disposed along a bottom side of the support member, a top opening defined in a top side of the sheath member; a biasing member disposed in the interior space of the support member; a latch member for latching the retractable member in the exposed position, the latch member having a release button being receivable in the top opening of the sheath member and the top slot of the support member, thereby locking the sheath member and the support member against further relative movement; a compression member attached to the rear end of the sheath member at an attachment portion of the compression member, the compression member being tapered rearward from the rear end of the sheath member, the compression member being configured to bias the biasing member toward a rear end of the support member, wherein the rear end of the support member has a slot that allows the compression member to pass by; and a self-locking mechanism configured to translate an axial movement of the retractable member when the retractable member is moving from the exposed position to the guarded position to rotation, thereby preventing the retractable member from moving forward relative to the sheath member and self-locking the retractable member in the guarded position.
