Abstract

A surgical hair trimmer is provided including a handle assembly including a power source, a drive motor connected to the power source and having a drive shaft extending therefrom, and a release mechanism configured and adapted for single handed operation; and a blade assembly including a pair of blades wherein at least one of the pair of blades is movable with respect to the other of the pair of blades, an interconnect configured and adapted to operatively couple the drive shaft to the movable blade when the blade assembly is connected to the handle assembly, and engagement structure configured and adapted to selectively engage the release mechanism of the handle assembly. In use, actuation of the release mechanism, when the blade assembly is connected to the handle assembly, jettisons the blade assembly from the handle assembly.

Claims

1. A surgical hair trimmer, comprising:

a handle assembly including;

a handle housing configured and dimensioned to house a power supply and a drive motor, wherein the drive motor includes a drive shaft extending through a distal end of the handle housing; and

a release mechanism associated with the handle housing, the release mechanism including at least one tang having a proximal end extending into the handle housing and a distal end extending out of the handle housing and being configured to engage a blade assembly; and

at least one release button operatively associated with a respective tang; and

a blade assembly selectively connectable to the handle assembly, the blade assembly including;

a blade housing configured and dimensioned to house a pair of trimmer blades;

an interconnect operatively connected to one of the pair of trimmer blades to impart movement to the one trimmer blade, the interconnect being configured and adapted to selectively operatively engage the drive shaft of the drive motor when the blade assembly is connected to the handle assembly; and

an engagement structure formed in blade housing for selectively engaging the distal end of each tang of the release mechanism,

wherein when the blade assembly is connected to the handle assembly the distal end of each tang of the release mechanism of the handle assembly engages with a corresponding engagement structure of the blade housing of the blade assembly, and wherein actuation of the at least one release button of the release mechanism jettisons the blade assembly from the handle assembly.

2. The surgical hair trimmer according to claim 1, wherein a pair of release buttons are provided on side surfaces of the handle housing for operative engagement with at least a pair of tangs.

3. The surgical hair trimmer according to claim 1, wherein a single release button is provided on a rear end of the handle housing for operative engagement with at least one tang.

4. The surgical hair trimmer according to claim 1, wherein the distal end of at least one tang extends in an outward direction.

5. The surgical hair trimmer according to claim 1, further comprising at least one visual indicator supported on the handle housing.

6. The surgical hair trimmer according to claim 1, wherein a distal end of the handle housing includes a shroud extending therefrom.

7. The surgical hair trimmer according to claim 1, wherein the drive shaft of the drive motor extends through a distal wall of the handle housing, and wherein a sealing member is interposed between the drive shaft and the distal wall of the handle housing.

8. The surgical hair trimmer according to claim 1, wherein each of the release buttons is over-molded.

9. The surgical hair trimmer according to claim 1, further comprising an identification tag associated with the handle assembly for recognition with a corresponding identification tag of a charging base.

10. The surgical hair trimmer according to claim 1, for use with an anti-theft system, wherein the anti-theft system includes:

an electrical outlet connector configured and adapted for electrical connection to an electrical outlet and defining a proprietary configuration of electrical contact receptacles; and

a power cord including a power cord connector electrically connected to an end thereof, wherein the power cord connector includes electrical contacts complementing the electrical contact receptacles of the electrical outlet connector.

11. A surgical hair trimmer, comprising:

a handle assembly including a power source, a drive motor connected to the power source and having a drive shaft extending therefrom, and a release mechanism configured and adapted for single handed operation; and

a blade assembly including a pair of blades wherein at least one of the pair of blades is movable with respect to the other of the pair of blades, an interconnect configured and adapted to operatively couple the drive shaft to the movable blade when the blade assembly is connected to the handle assembly, and engagement structure configured and adapted to selectively engage the release mechanism of the handle assembly,

wherein actuation of the release mechanism, when the blade assembly is connected to the handle assembly, jettisons the blade assembly from the handle assembly.

12. The surgical hair trimmer according to claim 11, wherein the release mechanism includes at least one tang having a proximal end extending into a handle housing of the handle assembly and a distal end extending out of the handle housing, the distal end of each tang being configured to engage the blade assembly;

and at least one release button operatively associated with a respective tang.

13. The surgical hair trimmer according to claim 12, wherein the engagement structure is formed in a blade housing of the blade assembly for selectively engaging the distal end of each tang of the release mechanism.

14. The surgical hair trimmer according to claim 12, wherein a pair of release buttons are provided on side surfaces of the handle housing for operative engagement with at least a pair of tangs.

15. The surgical hair trimmer according to claim 12, wherein a single release button is provided on a rear end of the handle housing for operative engagement with at least one tang.

16. The surgical hair trimmer according to claim 11, wherein the handle assembly further includes at least one visual indicator.

17. The surgical hair trimmer according to claim 11, wherein a distal end of a handle housing of the handle assembly includes a shroud extending therefrom.

18. The surgical hair trimmer according to claim 11, wherein the drive shaft of the drive motor extends through a distal wall of a handle housing of the housing assembly, and wherein a sealing member is interposed between the drive shaft and the distal wall of the handle housing.

19. The surgical hair trimmer according to claim 12, wherein each release button is over-molded.

20. The surgical hair trimmer according to claim 11, further comprising an identification tag associated with the handle assembly for recognition with a corresponding identification tag of a charging base.

21. The surgical hair trimmer according to claim 11, for use with an anti-theft system, wherein the anti-theft system includes:

an electrical outlet connector configured and adapted for electrical connection to an electrical outlet and defining a proprietary configuration of electrical contact receptacles; and

a power cord including a power cord connector electrically connected to an end thereof, wherein the power cord connector includes electrical contacts complementing the electrical contact receptacles of the electrical outlet connector.
