Abstract

A device and method are set forth for performing hair grafts which includes a housing, plunger with a needle, and a carriage containing an inventory of hair grafts to be placed. The plunger is placed at an extended position where the needle extends from the catheter and the needle and catheter are inserted into the tissue. The plunger and needle are withdrawn and the carriage is indexed to position a graft. The plunger is moved to urge the graft from the carriage through the catheter into the tissue for transplantation.

Claims

1. A device for serially transplanting hair grafts comprising;

a housing supporting a hollow catheter;

a plunger moveably disposed on the housing and having a needle with an incising tip adapted to be received into the hollow of the catheter to move therethrough, said plunger moveable between a withdrawn position whereat the needle is withdrawn from the catheter and an extended position whereat the needle tip extends from the catheter for fashioning an incision to receive a graft therein;

a cartridge including a plurality of openings each adapted to pass said needle as the plunger moves from the withdrawn to the extended position and to retain a graft to be transplanted; and

said cartridge mounted to the housing for positioning the openings to align with the catheter for displacement of the graft by the needle from the cartridge through the catheter into the incision as the plunger is moved between the withdrawn to the extended position.

2. The device of claim 1 wherein the cartridge defines a strip having said openings along its length.

3. The device of claim 1 wherein the cartridge is a circular disk having said openings about its circumference.

4. The device of claim 1 wherein said cartridge is indexable to serially align the openings with the catheter.

5. The device of claim 3 wherein said cartridge includes circumferentially aligned projections including an axial throughbore to define each of said openings.

6. A device for serially transplanting hair grafts into incisions made in the skin comprising;

a housing supporting a hollow catheter;

a plunger moveably disposed on the housing and having a spike having an incising tip adapted to be received into the hollow of the catheter to move therethrough, said plunger moveable between a withdrawn position whereat the spike is withdrawn from the catheter and an extended position whereat the spike extends from the catheter for fashioning an incision to receive a graft therein;

a cartridge strip including aligned therealong a plurality of openings each adapted to pass said spike as the plunger moves from the withdrawn to the extended position and to retain a graft to be transplanted; and

said cartridge strip mounted to the housing for serially positioning the openings to a drive position whereat an opening containing a graft is aligned with the catheter for displacement of the graft by the spike from the cartridge strip through the catheter into the incision as the plunger is moved between the withdrawn to the extended position.

7. The device of claim 6 wherein said cartridge strip is indexable to serially position said openings to said drive positions.

8. A device for serially transplanting hair grafts into incisions made in the skin comprising;

a housing supporting a hollow catheter;

a plunger moveably disposed on the housing and having a spike adapted to be received into the hollow of the catheter to move therethrough, said plunger moveable between a withdrawn position whereat the spike is withdrawn from the catheter and an extended position whereat the spike extends from the catheter for incising and dilating the skin to receive a graft;

a cartridge disk including aligned circumferentially therealong a plurality of openings each adapted to pass said spike as the plunger moves from the withdrawn to the extended position and to retain a graft to be transplanted; and

said cartridge disk mounted to the housing for serially positioning the openings to a drive position whereat an opening containing a graft is aligned with the catheter for displacement of the graft by the spike from the cartridge disk through the catheter into the incision as the plunger is moved between the withdrawn to the extended position.

9. The device of claim 8 wherein said cartridge disk is indexable to serially position said openings to said drive positions.

10. A method for placing hair grafts in an incision in the skin comprising;

providing a device including a housing having a hollow sleeve, a plunger having a pin adapted to be received into the hollow of the sleeve and moveable disposed on the housing for movement between a withdrawn position and an extended position and a cartridge having a plurality of openings each adapted to register with the sleeve and to retain a graft;

locating the sleeve in an incision;

moving the plunger from the withdrawn position toward the extended position for the pin to urge a graft from an opening through the sleeve into the incision for implantation thereof;

withdrawing the plunger to remove the pin from the sleeve; and

repositioning the cartridge to register another opening containing a graft with the sleeve.

11. The method of claim 10 including repositioning the cartridge in response to movement of the plunger.

12. A device for serially transplanting hair grafts into tissue which has been incised and dilated comprising;

a housing;

a cartridge disposed on the housing and having a plurality of openings each adapted to retain a graft for transplantation thereof;

said cartridge indexable to serially align openings to a delivery position; and

means for moving the graft from said cartridge opening at the delivery position into the tissue for transplantation thereof.

13. The device of claim 12 wherein the cartridge is a strip having a plurality of said openings along the length thereof.

14. The device of claim 12 wherein the cartridge is a disk having said openings disposed in a circular pattern and said cartridge is indexably rotatable to serially align said openings to said delivery position.

15. The device of claim 12 wherein said graft moving means includes a plunger moveably disposed on the housing and having a needle adapted to be received into the hollow of a catheter to move there through, said plunger moveable between a withdrawn position whereat the needle is withdrawn from the catheter to an extended position to extend through the opening aligned at the delivery position to move a graft therefrom through the catheter into the dilated incision.

16. A device for serially transplanting hair grafts into tissue which has been incised and dilated comprising:

a housing;

a cartridge strip disposed on the housing and having a plurality of openings along the length thereof each adapted to retain a graft for transplantation thereof;

said cartridge strip indexable to serially align openings to a delivery position; and

means for moving the graft from cartridge opening at the delivery position into the tissue for transplantation thereof.

17. A device for serially transplanting hair grafts into tissue which has been incised and dilated comprising:

a housing;

a cartridge disk disposed on the housing and having a plurality of openings disposed in a circular pattern each adapted to retain a graft for transplantation thereof;

said cartridge disk indexable to serially align openings to a delivery position; and

means for moving the graft from cartridge opening at the delivery position into the tissue for transplantation thereof.
