摘要：
An implant insertion system comprising: an implant (42, 542)； at least one insertion tip (50A, 50, 250, 550A) secured to said implant, each insertion tip having a conical distal end (54), a proximal end (52), a base (58) extending proximally from said conical distal end and a central lumen (60) formed in said base having an opening facing the proximal end of said insertion tip； and an insertion device (20A, 20) having an outer shaft (28, 228) and a locking assembly (130, 230) provided at a distal end (32A, 32, 232) of said outer shaft that can be inserted into the opening of the central lumen to selectively block said insertion tip to said blocking assembly, said blocking assembly having an external dimension that can be changed from an expanded state, to block said insertion tip to said coupling assembly, to a state not expanded to unlock said insertion tip of said locking assembly； wherein said locking assembly has a proximal end attached to the distal end of said external axis, a distal end, a central opening extending between the proximal end and the distal end of said engagement assembly, and a first and second latches (132 and 134) at the distal end of said locking assembly, wherein said first and second latches have respective first and second latch pins (138 and 144) that move away from each other, wherein said first and second latches second, they are elastic and usually flex inwards towards each other； characterized in that the system further comprises a tip pin (114) disposed within the central opening of said locking assembly, said tip pin having a proximal end (116), a distal end (118), an axis (120) which extends between the proximal and distal ends, a neck of reduced diameter (122) formed on said shaft, and an annular base (124) at the proximal end of said tip pin, wherein said neck of reduced diameter of said pin tip has a diameter (D2) that is smaller than the diameter of said axis at the proximal and distal ends of said tip pin, and said annular ba
