Abstract
A skin grafting system includes a plurality of hollow microneedles actuatable between a retracted position and an extended position. The system further includes a rigid member coupled to plurality of hollow microneedles, and a latch assembly having at least one latch moveably coupled to the latch assembly. The at least one latch is configured to move during actuation of the plurality of hollow microneedles, and the at least one microneedles are in the extended position.
Claims20
A skin grafting system comprising:
- a plurality of hollow microneedles actuatable between a retracted position and an extended position;
- a rigid member coupled to the plurality of hollow microneedles;
- and
- a latch assembly comprising at least one latch coupled to the latch assembly,
- wherein the at least one latch is configured to inhibit movement of the rigid member when the plurality of hollow microneedles are in the extended position.
A skin grafting system comprising:
- a carrier actuatable between a retracted position and an extended position;
- a plurality of hollow microneedles coupled to the carrier and configured to extract tissue cores from a donor site as the carrier moves from a retracted position to an extended position and back to a retracted position;
- and
- a latch configured to move between a plurality of positions, including a latched position restricting movement of the carrier from the extended position to the retracted position to thereby lock the plurality of hollow microneedles in a position configured to engage the donor site.
A system for securing a plurality of microneedles during a skin grafting process, the system comprising:
- a rigid member coupled to a proximal end of the plurality of microneedles;
- and
- a latch assembly comprising:
- at least one pair of latches, each latch moveably coupled to the latch assembly and configured to engage the rigid member;
- and
- a spring disposed between the at least one pair of latches, and configured to bias the at least one pair of latches to a latched position, and
- wherein the at least one pair of latches are configured to inhibit movement of the rigid member when in the latched position.
