Abstract
In an embodiment, there is a safety scalpel having a handle, and a replaceable blade cartridge assembly that is releasably attached to the handle. The handle comprises a first end and a second end. The blade cartridge assembly comprises a housing that can be slideably mounted onto the second end of the handle, a blade holder that can be disposed within the housing, and a blade that can be attached to the blade holder. The safety scalpel has a resilient lock member that prevents the cartridge assembly from being detached from the handle during use.
Claims24
A safety scalpel comprising:
- a handle comprising a locking aperture;
- a resilient lock member;
- and
- a blade cartridge releasably attached to the handle, the blade cartridge comprising:
- a blade;
- a housing;
- and
- a blade holder in communication with the blade;
- wherein the blade holder is configured to allow the blade to extend between a stowed position in a pre-cutting state of the blade holder and a cutting position upon activation of the blade holder;
- wherein the resilient lock member is disposed within the housing;
- wherein in the pre-cutting state of the blade holder, the resilient lock member is in an unbiased condition where the resilient lock member is disengaged from the locking aperture of the handle;
- and
- wherein upon activation of the blade holder, the resilient lock member engages the blade holder and is moved by the blade holder into the locking aperture of the handle to lock the blade cartridge to the handle when the blade is in the cutting position.
A replaceable blade cartridge for releasably attaching to a handle to form a safety scalpel, the replaceable blade cartridge comprising
- a blade;
- a housing;
- a blade holder in communication with the blade, wherein the blade holder is configured to allow the blade to extend between a stowed position in a pre-cutting state of the blade holder and a cutting position upon activation of the blade holder;
- and
- a resilient lock member disposed within the housing, wherein the resilient lock member is in an unbiased condition when the blade holder is in the pre-cutting state such that the resilient lock member is configured to disengage a locking aperture of the handle, and wherein the resilient lock member is configured to engage the blade holder to lock the blade cartridge to the handle only when the blade is in the cutting position upon activation of the blade holder;
- wherein the resilient lock member comprises a resilient arm portion and a catch extending from the resilient arm portion;
- and
- wherein the blade holder has a surface adapted to engage the resilient arm portion of the resilient lock member and allow the catch of the resilient lock member to be moved into the locking aperture of the handle to lock the blade cartridge to the handle when the blade is in the cutting position upon activation of the blade holder.
A safety scalpel comprising:
- a handle comprising a locking aperture;
- a resilient lock member comprising a resilient arm portion and a catch extending from the resilient arm portion;
- and
- a blade cartridge releasably attached to the handle comprising:
- a blade;
- a housing having disposed therein the resilient lock member;
- and
- a blade holder in communication with the blade comprising a surface;
- wherein the blade holder has a pre-cutting state in which the blade is in a stowed position where the resilient lock member is in an unbiased condition and the resilient lock member is disengaged from the locking aperture of the handle;
- wherein upon activation of the blade holder, the surface of the blade holder engages the resilient arm portion of the resilient lock member and allows the catch of the resilient lock member to move into the locking aperture of the handle to lock the blade cartridge to the handle when the blade is in the cutting position;
- and
- wherein the blade holder is configured to allow the blade to move between and into the stowed position and the cutting position and vice versa.
