Abstract
Systems and methods for separating an internal bone fixation device from an introducer are disclosed. In some embodiments, a separation system includes a stabilizer configured to slide over an introducer for delivery of a bone fixation device to a bone cavity, the stabilizer being further configured to score a proximal end of the bone fixation device; and a separator configured to engage the introducer and to provide an impact to the introducer to separate the introducer from the bone fixation device.
Claims23
A separation system comprising:
- a stabilizer configured to slide over an introducer for delivery of a bone fixation device to a bone cavity, the stabilizer being further configured to score a proximal end of the bone fixation device;
- wherein the stabilizer includes a tube assembly having a cutting distal edge and a swivel assembly engaged to a proximal end of the tube assembly for rotating the tube assembly;
- and
- a separator configured to engage the introducer and to provide an impact to the introducer to separate the introducer from the bone fixation device.
A separation system comprising:
- an introducer having a distal end and a proximal end;
- a bone fixation device engaged to the distal end of the introducer;
- a stabilizer advanceable over the introducer to a proximal end of the bone fixation device, the stabilizer having a cutting distal edge to score the proximal end of the bone fixation device;
- and
- a separator having a shaft attachable to the proximal end of the introducer, and a hammer slidably disposed along the shaft to provide an impaction force on the introducer to separate the introducer from the bone fixation device.
A method of separating an internal bone fixation device from an introducer, the method comprising:
- forming an internal bone fixation device engaged to an introducer in an intramedullary cavity of a bone;
- scoring a proximal end of the internal bone fixation device;
- and
- providing an impact force on the introducer to separate the introducer from the bone fixation device.
A separation system comprising:
- a stabilizer configured to slide over an introducer for delivery of a bone fixation device to a bone cavity, the stabilizer being further configured to score a proximal end of the bone fixation device;
- and
- a separator configured to engage the introducer and to provide an impact to the introducer to separate the introducer from the bone fixation device;
- wherein the separator comprises a shaft attachable to the introducer and a hammer slidably disposed on the shaft to provide an impact force on the introducer.
