anchor receiver 118 with a second surgical site 32 and presses handle 120 distally to release nub 126 from stop 145 the operator then rotates handle 120 in the direction of arrow r 2 to move nub 126 further along second lateral extent 144 to junction 143 where nub 126 enters third longitudinal extent 142 referring to fig5 c the operator applies a force f2 to handle 120 moving nub 126 distally along third longitudinal extent 142 such that contact face 129 of plunger member 128 pushes against proximal end 93 of anchor 90 pushing anchor tip 92 into bone 30 at site 32 penetration proceeds until nub 126 reaches end 141 at which time anchor assembly 40 is fully deployed from insertion tool 100 the operator then removes insertion tool 100 from surgical site 32 pulls on spacer 60 to shorten suture portion 62 and thus hold soft tissue 34 to bone 30 slip knot 54 acts to limit loosening of the suture for example referring to fig6 a a suture anchor insertion tool 300 permitting arthroscopic insertion of two anchors coupled by a suture to e g attach soft tissue to bone includes an outer tubular member 310 for housing the two anchors an actuating.
