Abstract

A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.

Claims (41)

1. A method comprising:

obtaining access to a surgical site including a bone;

positioning a mixing device adjacent to the bone, the mixing device comprising:

a vial holder comprising a cavity,

a container comprising a ledge and a vial-breaking device, the vial holder being positioned within the container, and

a mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within a body of the syringe; and

moving the mixing vessel relative to the container from a first orientation to a second orientation to drive contents of the syringe out of the port and into the bone.

2. The method recited in claim 1 , wherein when the mixing vessel is in the first orientation, the ledge is spaced apart from the plunger.

3. The method recited in claim 1 , wherein when the mixing vessel is in the second orientation, the ledge engages the plunger to move the plunger relative to the body.

4. The method recited in claim 1 , wherein:

when the mixing vessel is in the first orientation, the ledge is spaced apart from the plunger; and

when the mixing vessel is in the second orientation, the ledge engages the plunger to move the plunger relative to the body.

5. The method recited in claim 1 , wherein the plunger is spaced apart from the vial holder.

6. The method recited in claim 1 , further comprising positioning a vial within the cavity, wherein moving the mixing vessel relative to the container from the first orientation to the second orientation drives contents of the vial out of the port and into the bone.

7. The method recited in claim 1 , further comprising positioning a vial within the cavity, wherein moving the mixing vessel relative to the container from the first orientation to the second orientation causes the vial-breaking device to break the vial such that contents of the vial out are moved of the port and into the bone as the mixing vessel moves relative to the container from the first orientation to the second orientation.

8. The method recited in claim 1 , wherein obtaining access to the surgical site includes accessing the surgical site through a mini-incision.

9. The method recited in claim 1 , wherein obtaining access to the surgical site includes accessing the surgical site through a sleeve that provides a protected passageway.

10. The method recited in claim 1 , wherein obtaining access to the surgical site includes retracting tissue.

11. The method recited in claim 1 , wherein obtaining access to the surgical site includes creating a surgical pathway using a cutting instrument.

12. The method recited in claim 1 , further comprising preparing tissue surfaces of the bone using a preparation instrument.

13. The method recited in claim 1 , further comprising aspirating an area adjacent to the bone.

14. The method recited in claim 1 , further comprising irrigating an area adjacent to the bone.

15. The method recited in claim 1 , further comprising performing a surgical procedure for treating or repairing the bone.

16. The method recited in claim 15 , wherein the surgical procedure is performed prior to positioning the mixing device adjacent to the bone.

17. The method recited in claim 15 , wherein the surgical procedure is performed prior to moving the mixing vessel relative to the container from the first orientation to the second orientation.

18. The method recited in claim 15 , wherein the surgical procedure is selected from the group consisting of open surgery, mini-open surgery, minimally invasive surgery and percutaneous surgical implantation.

19. A method comprising:

obtaining access to a surgical site including a bone;

positioning a mixing device adjacent to the bone, the mixing device comprising:

a vial holder comprising a cavity,

a container comprising a ledge and a vial-breaking device, the vial holder being positioned within the container, and

a mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within a body of the syringe, the plunger being spaced apart from the vial holder;

positioning a vial within the cavity; and

moving the mixing vessel relative to the container from a first orientation to a second orientation to drive contents of the vial out of the port and into the bone.

20. A method comprising:

obtaining access to a surgical site including a bone;

positioning a mixing device adjacent to the bone, the mixing device comprising:

a vial holder comprising a cavity,

a container comprising a ledge and a vial-breaking device, the vial holder being positioned within the container, and

a mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within a body of the syringe, the plunger being spaced apart from the vial holder; and

moving the mixing vessel relative to the container from a first orientation in which the ledge is spaced apart from the plunger to a second orientation in which the ledge engages the plunger to drive contents of the syringe out of the port and into the bone.
