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 1):
A self-locking retractable surgical knife, comprising:\n a sheath member having front and rear ends; a retractable member including a support member and a blade supported by the support member, wherein the support member has a front end, a rear end and 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 blade is guarded in the sheath member, and an exposed position wherein the blade extends out of the sheath member; top and bottom elongated and longitudinally extended slots formed on the support member, wherein the top slot is defined in a top wall of the support member and the bottom slot is defined in a bottom wall of the support member, a biasing member disposed in the interior space of the support member; a latch member disposed in the interior space of the support member, the latch member having a release button projecting through the top slot of the support member and an opening defined in a top wall of the sheath member in this order, the latch member having a bottom section projecting through the bottom slot of the support member and abut the inner surface of the bottom wall of the sheath member; 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.
