Anti-popping devices and methods for hair implantation
A system and method for implanting follicular units (FUs) into a body surface while suppressing expulsion of previously-implanted FUs. The system is particularly useful to facilitate hair transplant procedures. FUs are implanted in a body surface from an implant tool or needle that may be incorporated within an automated or robotic system, or may form part of a semi-automated or even manual apparatus. An anti-popping member prevents expulsion of the FUs adjacent to the location at which an FU is being implanted. The anti-popping member may be carried on the implant device, or may be a flexible membrane applied to the body surface. If on the device, the anti-popping member may be arranged near the distal tip thereof and may be shaped and mounted so as to conform to uneven body surfaces.
1. A method of implanting follicular units within a body surface, comprising:
implanting one or more follicular units within a body surface while suppressing expulsion of previously implanted follicular units positioned adjacent and around a circumference of an implanting tool when a tip of the implanting tool enters the body surface,
wherein suppressing is accomplished with a use of an anti-popping member configurable to extend radially outward from the implanting tool and covering an area substantially around the circumference of the implanting tool.
2. The method of claim 1 , wherein the anti-popping member comprises a flange extending radially outward, and wherein suppressing comprises contacting an area on the body surface with at least a portion of the anti-popping member when inserting the implanting tool into the body surface.
3. The method of claim 1 , wherein suppressing comprises conforming the anti-popping member to a portion of the body surface.
4. The method of claim 3 , wherein conforming to the body surface comprises flexing the anti-popping member.
5. The method of claim 1 , wherein suppressing comprises pivoting the anti-popping member relative to the implanting tool to suppress expulsion of the at least one of the adjacent previously implanted follicular units.
6. The method of claim 1 , wherein implanting comprises expelling the one or more follicular units from a lumen of the implanting tool.
7. The method of claim 1 , comprising moving the implanting tool in a linear translation direction and moving the anti-popping member at least in a second direction different from the direction of the linear translation of the implanting tool.
8. The method of claim 1 , wherein suppressing comprises slidably moving the anti-popping member towards a distal end of the implanting tool.
9. The method of claim 1 , wherein the method is performed using a robotic system.
10. The method of claim 1 , wherein the anti-popping member comprises a bearing surface, the bearing surface arranged around the implanting tool, and suppressing comprises pivoting the bearing surface about the implanting tool.
11. The method of claim 1 , wherein the anti-popping member comprises a flexure undercut, and the method comprising using the flexure undercut to assist in flexing the anti-popping member to conform to the body surface.
12. The method of claim 1 , wherein the anti-popping member comprises fiducials or reference marks.
13. The method of claim 12 , comprising using the fiducials or reference marks as a guide in placing the implanting tool.
14. The method of claim 1 , wherein the anti-popping member comprises at least one anti-popping membrane and suppressing comprises covering a portion of the body surface with the at least one anti-popping membrane through which the implanting tool passes before piercing the body surface.
15. The method of claim 14 , wherein covering the portion of the body surface comprises applying the anti-popping membrane in a liquid form, and allowing the liquid form to at least partially solidify.
16. The method of claim 15 , wherein solidifying comprises drying.
17. The method of claim 14 , wherein the anti-popping membrane comprises an elastic material and self-seals on retraction of the implanting from the anti-popping membrane.
18. The method of claim 1 , wherein the anti-popping member comprises a multi-layered anti-popping membrane, wherein a first layer of the multi-layered anti-popping membrane is configured to suppress expulsion of the at least one previously implanted follicular unit, and further comprising suppressing the expulsion of a just-implanted follicular unit by use of a second layer of the multi-layered anti-popping membrane.
19. The method of claim 14 , further comprising removing the at least one anti-popping membrane from the body surface.
20. The method of claim 8 , further comprising preventing the anti-popping member from sliding up the implant tool during the implanting process.
21. The method of claim 1 , wherein one or more steps of the method are computer-controlled.
22. The method of claim 1 , comprising rotating the anti-popping member, a portion of the anti-popping member, or the anti-popping member together with the implanting tool to orient the anti-popping member for better conformance to the body surface.
