Into relatively hard structural opening, puncture tip 2 has good guiding role.
1 lateral surface of ground anchor body is equipped with several hangnail fins 101, and hangnail fin 101 penetrates relatively in ground anchor body 1
When in the opening in sclerous tissues, offset with the inner wall of relatively hard structural opening, once ground anchor body 1 is pierced into required depth
After degree, when by reversal interlocking relay, hangnail fin 101 is opened mutually to be stung ground anchor body 1 with the inner wall of relatively hard structural opening
It closes, avoids ground anchor body 1 from being reversed and draw out, the fixation of ground anchor body 1 is played an important role.
It is equipped with axial passage 5 inside the ground anchor body 1, is equipped with threading hole 4 inside puncture tip 2, threading hole 4 is set to
The two sides of 5 bottom of axial passage, puncture tip 2 are equipped with eyelet 3, and eyelet 3 is connected to 5 bottom of axial passage, the threading hole 4
It is inside equipped with suture 11, eyelet 3 carries out auxiliary threading when being threaded through in threading hole 4 for suture 11；It is worn when carrying out suture 11
When, suture 11 is folded in half into two strands from centre first, then penetrates doubling one end in ground anchor body 1 along axial passage 5, until
Then 3 position of eyelet of puncture tip 2 is penetrated threading hole 4 by Threading tool by eyelet 3, then by axial passage 5
It is pierced by；
The ground anchor body 1 is equipped with holdfast boss 6, is arranged with thermoplasticity set in the ground anchor body 1 on 6 top of holdfast boss
Cylinder 7, thermoplasticity sleeve 7 is equal with the outer diameter of ground anchor body 1,1 upper end of ground anchor body be equipped with internal thread segment 8, internal thread segment 8 with outside
Screw thread pillar 9 is connected, and external screw thread pillar 9 is arranged in the sliding slot 12 of tool collar 16；
In assembly, the four strands of sutures 11 for being penetrated and being pierced by by axial passage 5 penetrate the axial mistake of external screw thread pillar 9 jointly
It in string holes 10, is pierced by from the other end, is then connected in progress external screw thread pillar 9 with the internal thread segment 8 of ground anchor body 1；
9 side of external screw thread pillar is equipped with positioning convex tendon 13, and positioning convex tendon 13 is embedded in the positioning in tool collar 16
In card slot 14, is limited conducive to being slided in sliding slot 12 to external screw thread pillar 9, external screw thread pillar 9 is positioned, make it only
It can slide axially along tool collar 16, without can be carried out rotation；
16 upper end of tool collar connects workpiece lever 20, and workpiece lever 20 is equipped with suture card slot 19, for blocking
Suture 11,16 top lumen of tool collar, 17 side is equipped with eyelet 18, for being pierced by for suture 11；
When being assembled, after be pierced by from external screw thread pillar 9 four strands of sutures 11 are penetrated tool collar 16, and from tool
The eyelet 18 of casing 16 is pierced by, and blocks four strands of sutures 11 using suture card slot 19, external screw thread pillar 9 is then penetrated tool collar
In 16；
16 bottom end of tool collar is equipped with horizontal boss 15, horizontal boss 15 offset with thermoplasticity sleeve 7 and with thermoplasticity set
The diameter of cylinder 7 is equal；The distance between the horizontal boss 15 and holdfast boss 6 the thermoplasticity sleeve 7 will be liquefied
Length；The outside diameter of 7 three of the horizontal boss 15, holdfast boss 6 and thermoplasticity sleeve is equal, is conducive to ground anchor body 1
It penetrates in the hole opened up in advance in sclerous tissues.
It, will be by axially leading to before internal thread segment 8 is connected with external screw thread pillar 9 when carrying out assembly thermoplasticity sleeve 7
Four strands of sutures 11 that road 5 is penetrated and is pierced by pass through thermoplasticity sleeve 7, and the holdfast that thermoplasticity sleeve 7 is set in ground anchor body 1 is convex
On platform 6, then carries out internal thread segment 8 and be connected with external screw thread pillar 9.

In 20 side one end of workpiece lever of tool collar 16, energy body is led in setting, and the liquefied material of thermoplasticity sleeve 7 is contacted with sclerous tissues,
Ground anchor body 1 is fixed in sclerous tissues and being infiltrated into sclerous tissues' wall portion of opening by making liquefied material, or by being somebody's turn to do
Except liquefied material expansion (radially flowing) to the opening range, i.e., on the non-accessible side of sclerous tissues' layer, and possibly
Hard tissue surface is permeated in the non-accessible side of sclerous tissues' layer, ground anchor body 1 is fixed on except the range of sclerous tissues' opening.
Once solidifying again, penetrates the material in sclerous tissues and form shape mating connection between the sclerous tissues and ground anchor body 1.
The thermoplastic material of the thermoplasticity sleeve 7 includes thermoplastic polymer, for example can be reabsorbed or degradable poly-
Close object, such as the polymer (PLA, PLLA, PGA, PLGA) based on lactic acid and/or glycolic or polyhydroxyalkanoatefrom (PHA),
Polycaprolactone (PCL), polysaccharide, polysiloxanes (PD), polyanhydride, polypeptide or the corresponding copolymerization comprising the polymer as ingredient
Object or composite material；Or non-resorbable or nondegradable polymer, as polyolefin (such as polyethylene), polyacrylate,
Polymethyl acrylate, polycarbonate, polyamide, polyester, polyurethane, polysulfones, poly- aryl ketones, polyimides, polyphenylene sulfide or liquid
Crystalline polymer LCP, polyacetal resin, halogen polymer, particularly the polyolefin of halogenation, polyphenylene sulfide, polysulfones, polyethers, or contain
There are equivalent copolymer or composite material of the polymer as ingredient.
After the ground anchor body 1 assembled is pierced into relatively hard structural opening, leads energy body and thermoplasticity sleeve 7 liquefies, liquid
The material of change is contacted with sclerous tissues, and is gradually tightened suture 11 and pushed tool collar 16 and make its horizontal boss 15 and holdfast boss 6
Between spacing reduce, liquefied material infiltrates into sclerous tissues' wall portion of opening and ground anchor body 1 is fixed in sclerous tissues；Most
Afterwards, tool collar 16 is taken out, external screw thread pillar 9 is reversely rotated and removes it from ground anchor body 1, finally, can choose anchor
It follows closely the connection of the direct suture 11 of ontology 1 or unclamps two ends of suture 11, suture 11 can be taken out by holding 11 fold position of suture,
Line holdfast is completed to fix.
The technical principle of the invention is described above in combination with a specific embodiment, is only the preferred embodiment of the present invention.This
The protection scope of invention is not limited merely to above-described embodiment, and all technical solutions belonged under thinking of the present invention belong to the present invention
Protection scope.Those skilled in the art, which does not need to pay for creative labor, can associate other specific realities of the invention
Mode is applied, these modes will fall within the scope of protection of the present invention.
