Abstract
A safety scalpel, including a handle, a scalpel blade extending from the handle, a footplate pivotably connected to the handle, a biasing member operationally connected to the footplate for providing a biasing force urging the footplate to pivot away from the scalpel blade, and a slot formed through the footplate and positioned to pass the scalpel blade at least partially therethrough when the footplate is pivoted against the biasing force and towards the scalpel.
Claims6
A lightweight disposable scalpel blade guard assembly, comprising:
- an elongated handle portion defining a first major axis and having a proximal end, an oppositely disposed distal end, and a locking ridge positioned in the distal end;
- and
- a scalpel blade guard portion extending from the distal end;
- a pair of spaced guard members extending from the distal end and oriented parallel to the first major axis;
- a flat slotted member pivotably connected to the elongated handle portion and extending perpendicularly between and connecting the pair of spaced guard members;
- a slot formed in the flat slotted member;
- and
- a notched locking member defining a notch and connected to the flat slotted member and biased toward the elongated handle portion;
- wherein a biasing force urges the notch into locking engagement with the locking ridge;
- wherein when the notched locking member is pivoted away from the locking ridge and an urging force is applied to the notched locking member in a direction towards the flat slotted member, the flat slotted member is pivoted to move the slot towards the distal end.

A disposable scalpel, comprising:
- an elongated body portion having a proximal end and a distal end;
- first and second spaced elongated guard members extending from the distal end;
- a scalpel blade receiving slot formed in the distal end and positioned between the first and second spaced elongated guard members, such that a scalpel blade received in and extending from the scalpel blade receiving slot is flanked by the first and second spaced elongated guard members;
- a footplate pivotably connected to the distal end;
- a biasing member operationally connected to the footplate for providing a biasing force urging the footplate to pivot away from the distal end;
- a deploying slot formed through the footplate and positioned to pass the scalpel blade received in and extending from the scalpel blade receiving slot when the footplate is pivoted against the biasing force and towards the distal end;
- and
- a locking member operationally connected to the elongated body portion and to the footplate;
- wherein pivoting the footplate relative to the elongated body portion allows precise surgical control of extension of the scalpel blade through the scalpel blade receiving slot;
- and
- wherein the locking member is biased to lockingly engage the elongated body portion when the footplate is pivoted away from the distal end;
- and wherein application of a force overcoming the biasing force urges the locking member out of locking engagement with the elongated body portion and to pivot the footplate towards the distal end.

A safety scalpel, comprising:
- a handle;
- a scalpel blade extending from the handle;
- a footplate pivotably connected to the handle;
- a biasing member operationally connected to the footplate for providing a biasing force urging the footplate to pivot away from the scalpel blade;
- a slot formed through the footplate and positioned to pass the scalpel blade at least partially therethrough when the footplate is pivoted against the biasing force and towards the scalpel blade;
- a locking member operationally connected to the handle and to the footplate;
- wherein the locking member is biased to lockingly engage the handle when the footplate is pivoted away from the scalpel blade;
- and wherein application of a force overcoming the biasing force urges the locking member out of locking engagement with the handle and pivots the footplate towards the scalpel blade;
- wherein pivoting the footplate relative to the handle varies how far the scalpel blade extends through the slot.
