Abstract

Medical procedure trays and related methods are provided to accommodate joining a first non-sterile medical device with a second sterile medical device and maintaining required sterilization of the second sterile medical device to perform an associated medical procedure. One example of such medical procedures includes biopsy of a bone and/or associated bone marrow using a non-sterile powered driver and a sterile biopsy needle or biopsy needle set. Each medical procedure tray may include a containment bag or sterile sleeve. A coupler assembly, one or more sharps protectors, a biopsy sample ejector and/or associated ejector funnel may also be included. Some medical procedure trays may allow engaging a non-sterile powered driver with one end of a coupler assembly and sealing the non-sterile powered driver in a sterile sleeve or containment bag without compromising sterility of other components in the medical procedure tray.

First claim

What is claimed is:

1. An apparatus for obtaining a biopsy sample of a bone and/or associated bone marrow, the apparatus comprising:
an intraosseous device operable to penetrate the bone and associated bone marrow, the intraosseous device comprising:
a cannula extending from a first hub, the cannula having a longitudinal bore through the cannula; and
a stylet extending from a second hub, the second hub configured to releasably engage the first hub, and the cannula configured to slidably receive the stylet within the longitudinal bore of the cannula when the first hub is engaged to the second hub;

a powered driver including a housing defining a handle configured to be sized and shaped to fit a hand of an operator of the apparatus, the housing enclosing a motor and a power supply, the housing further including a trigger assembly electrically coupled to the power supply and operable to activate the motor to rotate the intraosseous device when the intraosseous device is releasably coupled to the powered driver;
a coupler assembly operable to releasably couple the intraosseous device to the powered driver, a first end portion of the coupler assembly configured to receive a portion of the intraosseous device, and a second end portion of the coupler assembly configured to receive a portion of the powered driver, the coupler assembly further configured to releasably engage the portion of the intraosseous device and the portion of the powered driver; and
a containment bag attached to the coupler assembly, the containment bag including an opening configured to receive and enclose the powered driver such that the operator may grasp the handle of the powered driver over the containment bag to prevent contamination of the handle, wherein the coupler assembly defines a first receptacle configured to receive the portion of the intraosseous device, and wherein the coupler assembly comprises a housing segment slidably disposed over an exterior portion of an elongated core of the coupler assembly, the housing segment operable to move along a longitudinal length of the coupler assembly from a first position to a second position to allow release of the portion of the intraosseous device from within the first receptacle.

2. The apparatus according to claim 1 , wherein the containment bag further includes a second opening attached to the coupler assembly and forms a fluid barrier between an inner volume defined by the containment bag configured to enclose the handle and the intraosseous device.

3. The apparatus according to claim 2 , wherein the coupler assembly is operable to allow the powered driver to rotate the intraosseous device without damage to the containment bag.

4. The apparatus according to claim 1 , wherein the power supply comprises a battery disposed within the housing and configured to supply power to the motor.

5. The apparatus according to claim 4 , wherein the housing of the powered driver further includes an indicator light.

6. The apparatus according to claim 5 , wherein the indicator light is disposed on a proximal end of the housing.

7. The apparatus according to claim 5 , wherein the indicator light is operable to indicate a level of the battery.

8. The apparatus according to claim 5 , wherein the indicator light is a light emitting diode.

9. The apparatus according to claim 5 , wherein the indicator light is operable to activate when a predetermined amount of electrical storage capacity of the battery has been used.

10. The apparatus according to claim 1 , wherein the powered driver further comprises a drive shaft configured to releasably engage the coupler assembly.

11. The apparatus according to claim 10 , wherein the drive shaft extends from a distal end of the housing.

12. The apparatus according to claim 11 , further comprising a tapered surface formed on an exterior portion of a distal end of the drive shaft.

13. The apparatus according to claim 1 , wherein the cannula comprises a cutting tip, and the cutting tip of the cannula and a tip of the stylet are operable to penetrate the bone as a single cutting unit.

14. The apparatus according to claim 1 , wherein an end of the first hub further comprises a Luer lock fitting.

15. The apparatus according to claim 1 , wherein the housing of the powered driver further includes an indicator light operable to indicate a level of the power supply, and wherein the cannula and the stylet are operable to penetrate the bone as a single cutting unit.

16. The apparatus according to claim 15 , wherein the powered driver further comprises a drive shaft with a distal end having an exterior portion including a tapered surface.
