Abstract
A tissue transfer device includes a handle and a chisel attached to the handle. A pusher rod or tamp extends through the chisel and is axially moveable relative to the chisel. A control mechanism coupled to the handle moves the tamp distally relative to the outer tube to expel a tissue graft from the chisel in a controlled manner. The tamp has a measurement scale that allows the user to leave the harvested graft in the harvest tool during measurement.
Claims8
A tissue transfer device comprising:
- a handle comprising a “T” shape and having a first surface and a second surface opposite the first surface, a through hole defined by the handle extending through a width of the handle;
- an outer tube having a proximal end, a distal end, and a cannulation extending between the proximal and distal ends, the proximal end coupled to the second surface of the handle such that the cannulation extends in line with the through hole, the distal end configured for insertion into tissue;
- an inner shaft extending through the cannulation of the outer tube such that a proximal end of the inner shaft projects from the first surface of the handle, the inner shaft axially moveable relative to the outer tube;
- and
- a control mechanism removably coupled to the handle in contact with the proximal end of the inner shaft, the control mechanism configured to move the inner shaft distally relative to the outer tube to expel a tissue graft from the outer tube.
