Abstract

An apparatus and methods are provided to penetrate a bone and associated bone marrow using a powered driver having a gear assembly and a motor. The powered driver may include an indicator operable to show status of a power supply associated with the powered driver. The power supply may include a battery power pack having a diamond shaped cross section. The powered driver may have a handle with a corresponding cross section.

Claims

1. A removable trigger guard comprising:

a body having a U-shaped cross-section, the body having first and second ends and first and second sides extending between the first and second ends, where the second end is closed such that the first and second sides are connected by the second end, and where an opening is defined through the first end to accept a trigger assembly of a powered driver; and

a pair of ribs disposed on the first and second sides of the trigger guard, each of the ribs extending outwardly from the respective side and away from the other of the pair of ribs;

the ribs configured to be contacted by a thumb of an operator ove the trigger guard from covering portions of the trigger assembly of the powered driver;

the trigger guard configured to be removably coupled to the powered driver that includes the trigger assembly, the trigger assembly having an external surface configured to be depressed to activate the powered driver, the first and second sides of the trigger guard configured to cover opposing lateral sides of the trigger assembly and the second end of the trigger guard configured to cover a front of the trigger assembly to prevent the trigger assembly from being depressed and to prevent operation of the powered driver when the trigger guard is coupled to the powered driver;

where portions of the first and second sides of the trigger guard form a flush surface with a surface of the handle of the powered driver when the trigger guard is coupled to the powered driver.

2. The removable trigger guard of claim 1, further comprising:

a lanyard having a first end coupled to the body and a second end configured to be coupled to the powered driver.

3. The removable trigger guard of claim 2, further comprising an opening configured to receive the first end of the lanyard.

4. The removable trigger guard of claim 2, where the lanyard is formed of a flexible material.

5. The removable trigger guard of claim 1, where the trigger guard is formed of a flexible material.

6. The removable trigger guard of claim 1, where the trigger guard is further configured to be slidably disposed on a portion of the handle of the powered driver.

7. The removable trigger guard of claim 1, where portions of the trigger guard comprise a shape that corresponds with adjacent portions of the handle of the powered driver when the trigger guard is coupled to the powered driver and covers the trigger assembly of the powered driver.

8. The removable trigger guard of claim 1, where the trigger guard extends a longitudinal length of the handle of the powered driver.

9. The removable trigger guard of claim 1, where the trigger guard extends less than a longitudinal length of the handle of the powered driver.

10. The removable trigger guard of claim 1, further comprising a pivot pin, the pivot pin configured to couple the trigger guard to a portion of the handle of the powered driver.

11. The removable trigger guard of claim 10, the trigger guard configured to rotate between a first position and a second position, where the trigger guard covers the trigger assembly in the first position.

12. The removable trigger guard of claim 1, where a portion of the trigger guard is adjacent to a cap of the powered driver when the trigger guard is coupled to the powered driver and covers the trigger assembly of the powered driver, the cap of the powered driver configured to control access to a power supply disposed within the handle of the powered driver.

13. The removable trigger guard of claim 12, where portion of the trigger guard adjacent to the cap forms a flush surface with the cap when the trigger guard is coupled to the powered driver and covers the trigger assembly of the powered driver.

14. The removable trigger guard of claim 1, where the ribs are disposed adjacent to a handle of the powered driver when the trigger guard is coupled to the powered driver.
