Abstract

A shielded surgical scalpel includes an elongate handle definingg a longitudinal axis and having a proximal portion and a distal portion. A blad e is fixedly attached to the handle. A shield is movable between a distal position where the shield prevents inadvertent access to the blade and a proximal position where the shield exposes the blade for use.

Claims (15)

1. A shielded surgical scalpel comprising:
an elongate handle having a proximal portion and a distal portion with a shoulder defined therebetween, wherein the handle defines a slot formed thereon with a distal upturned terminus having a tapered proximal edge and a proximal upturned terminus;
a blade fixedly attached to the handle;
a shield mounted onto the handle and being movable between a distal position wherein the shield substantially prevents inadvertent access to the blade and a proximal position wherein the shield allows the blade to be exposed for use wherein the shield includes an upwardly biased cantilevered digital activation section having an inwardly directed boss disposed in the slot.
2. The shielded surgical scalpel of claim 1 wherein the tapered proximal edge of the distal upturned terminus has a taper of about 60 degrees.
3. The shielded surgical scalpel of claim 1 wherein the boss includes a tapered proximal edge.
4. The shielded surgical scalpel of claim 3 wherein the tapered proximal edge of the boss has a taper of about 55 degrees.
5. A shielded surgical scalpel comprising:
an elongate handle having a proximal portion and a distal portion with a shoulder defined therebetween, wherein the handle defines a slot formed thereon with a proximal upturned terminus and a distal upturned terminus;
a blade fixedly attached to the handle;
a shield mounted onto the handle and being movable between a distal position wherein the shield prevents inadvertent access to the blade and a proximal position wherein the shield allows the blade to be exposed for use wherein the shield includes an upwardly biased cantilevered digital activation section having an inwardly directed boss disposed in the slot and wherein the shield includes a proximal edge and a gap is defined between the proximal edge of the shield and the shoulder when the shield is in the proximal position.
6. A shielded surgical scalpel comprising:
an elongate handle having a proximal portion and a distal portion with a shoulder defined therebetween, wherein the handle defines a slot formed thereon with a proximal upturned terminus and a distal upturned terminus;
a blade fixedly attached to the handle;
a shield having a proximal end and being mounted onto the handle and movable between a distal position wherein the shield prevents inadvertent access to the blade and a proximal position wherein the shield allows the blade to be exposed for use wherein the shield includes an upwardly biased cantilevered digital activation section having an inwardly directed boss disposed in the slot and wherein the distal portion of the elongate handle includes a visual indication of the operation of the shield.
7. The shielded surgical scalpel of claim 6 wherein the visual indication of the operation of the shield is a lock indicator line disposed on the distal portion of the handle that is aligned with the proximal end of the shield when the shield is in the distal position to indicate that the shield is in the distal position.
8. The shielded surgical scalpel of claim 6 wherein the visual indication of the operation of the shield is at least one arrow disposed on the distal portion of the handle that points either proximally or distally.
9. A shielded surgical scalpel comprising:

an elongate handle having a proximal portion and a distal portion with a shoulder defined therebetween, wherein the handle defines a slot formed thereon with a proximal upturned terminus and a distal upturned terminus;
a blade fixedly attached to the handle;
a shield having a bottom distal edge and being mounted onto the handle and movable between a distal position wherein the shield prevents inadvertent access to the blade and a proximal position wherein the shield allows the blade to be exposed for use wherein the shield includes an upwardly biased cantilevered digital activation section having an inwardly directed boss disposed in the slot and wherein the bottom distal edge of the shield defines a curve that corresponds to the curve of a standard blade.
10. A shielded surgical scalpel comprising:
an elongate handle having a proximal portion and a distal portion with a shoulder defined therebetween, wherein the handle defines a slot formed thereon with a distal upturned terminus having a tapered proximal edge and a proximal upturned terminus;
a blade fixedly attached to the handle;
a shield having a proximal end and a bottom distal edge mounted onto the handle and movable between a distal position wherein the shield prevents inadvertent access to the blade and a proximal position wherein the shield allows the blade to be exposed for use wherein the shield includes an upwardly biased cantilevered digital activation section having an inwardly directed boss disposed in the slot and wherein the distal portion of the elongate handle includes a visual indication of the operation of the shield and a gap is defined between the proximal end of the shield and the shoulder when the shield is in the proximal position and wherein the bottom distal edge of the shield defines a curve corresponding to the curve of a standard blade.
11. The shielded surgical scalpel of claim 10 wherein the tapered proximal edge has a taper of about 60 degrees.
12. The shielded surgical scalpel of claim 10 wherein the boss includes a tapered proximal edge.
13. The shielded surgical scalpel of claim 12 wherein the tapered proximal edge of the boss has a taper of about 55 degrees.
14 The shielded surgical scalpel of claim 10 wherein the visual indication of the operation of the shield is a lock indicator line disposed on the distal portion of the handle that is aligned with the proximal end of the shield when the shield is in the distal position to indicate that the shield is in the distal position.
15. The shielded surgical scalpel of claim 10 wherein the visual indication of the operation of the shield is at least one arrow disposed on the distal portion of the handle that points either proximally or distally.
