Abstract
A surgical fastener includes a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip. A method of using the surgical fastener includes engaging an end of a driver with a recess in a head of the surgical fastener, including inserting an extension at the end of the driver into the passage, and inserting the fastener into a bore in a bone during which the extension of the driver abuts a trailing end of the shaft of the pin to prevent the pin from moving in a direction from the leading end to the trailing end relative to the fastening body.
Claims17
A surgical fastener comprising:
- a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, wherein the fastening body includes a head, a shaft portion, and a mesh portion;
- and
- a pin having an enlarged tip and a non-threaded shaft, the non-threaded shaft at least partially disposed within the passage,
- wherein in a resting configuration of the surgical fastener, a maximum outer diameter of the shaft portion is substantially similar to a maximum outer diameter of the mesh portion, and
- wherein in the resting configuration of the surgical fastener, a portion of the passage located proximally of the pin is unobstructed to permit movement of the pin within the passage.
A method of using a surgical fastener, comprising:
- engaging an end of a driver with a recess in a head of a surgical fastener, the fastener comprising a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip, wherein the fastening body includes a shaft portion and a mesh portion, and wherein the step of engaging includes inserting an extension at the end of the driver into the passage;
- and
- inserting the fastener into a bore in a bone during which the extension of the driver abuts a trailing end of the shaft of the pin to prevent the pin from moving in a direction from the leading end to the trailing end relative to the fastening body,
- wherein in a resting configuration of the surgical fastener, a maximum outer diameter of the shaft portion is substantially similar to a maximum outer diameter of the mesh portion, and
- wherein in the resting configuration of the surgical fastener, a portion of the passage located proximally of the pin is unobstructed to permit movement of the pin within the passage.
A method of using a surgical fastener, comprising:
- selecting one of a passive driver and an active driver, the passive driver having an end with a non-circular cross section, wherein the end of the passive driver includes an extension having a maximum outer diameter smaller than a maximum outer diameter of the end with the non-circular cross section, the active driver having an end with a non-circular cross section terminating in a planar surface;
- engaging the end of the selected driver with a recess in a head of a surgical fastener, the fastener comprising a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip, wherein the fastening body includes a shaft portion and a mesh portion, and wherein when the passive driver is selected, the step of engaging further includes inserting the extension at the end of the passive driver into the passage;
- and
- inserting the fastener into a bore in a bone,
- wherein in a resting configuration of the surgical fastener, a maximum outer diameter of the shaft portion is substantially similar to a maximum outer diameter of the mesh portion, and
- wherein in the resting configuration of the surgical fastener, a portion of the passage located proximally of the pin is unobstructed to permit movement of the pin within the passage.
