Abstract
An intramedullary nail comprising an outer tubular sheath, a flexible rod and a driver element mobile within the sheath longitudinally with an engagement element formed out of the wall of the tubular sheath. After the nail has been inserted, distal end first, into the intramedullary cavity, the flexible rod is pulled, thereby engendering the driver element to advance the engagement element into the cortical bone, thus keeping the intramedullary nail in position within the intramedullary cavity.
Claims20
A device for the implantation into osseous material to facilitate healing, comprising:
- an elongated tubular body wherein the elongated tubular body contains;
- a) a mobile elongated rod;
- b) an anchoring element attached to the elongated tubular body;
- and
- c) a driver attached to the elongated rod
- wherein the driver can move substantially along the length of the elongated tubular body and engages the anchoring element thereby causing the anchoring element to protrude laterally through the elongated tubular body and engage the surrounding osseous material.
A device for the implantation into compromised osseous material comprising:
- an elongated tubular body wherein the elongated tubular body contains:
- a) a mobile elongated rod;
- b) an anchoring element attached to the elongated tubular body;
- and
- c) a driver attached to the mobile elongated rod wherein
- i) the driver moves within the elongated tubular body and engages the anchoring element causing the anchoring element to extend out of the elongated tubular body to engage the surrounding material;
- and
- ii) the driver remains engaged with the anchoring element holding the anchoring element in position until the driver is moved a second time.
A method for facilitating the healing of damaged osseous material comprising:
- a) inserting an elongated tubular body into the osseous material wherein the elongated tubular body contains a mobile elongated rod attached to a driver within the elongated tubular body;
- b) moving the mobile elongated rod within the elongated tubular body thereby causing the driver to engage an anchoring element attached to the elongated tubular body;
- and
- c) causing the anchoring element to engage a surrounding osseous material and hold the tubular body in place.
