Description
Technical field
The present invention relates to a kind of band line holdfast, particularly a kind of half-thread band line holdfast.
Background technology
Holdfast reconnects soft tissue and bone clinically by suture, stationary burst tendon in holdfast embedment sclerotin
Tissue, to reach the purpose of tendon-bone healing.Holdfast of the prior art is has knot to design, i.e., the suture of holdfast end is in outside
Knot and fix.Publication No. CN104027140A discloses a kind of patent application of the key name for " three pore area line holdfasts ", and it is in hand
During art, ground anchor body is fixed on bone, each threading hole respectively penetrates suture, and make suture both ends be respectively embedded into
In the wire casing that the import of threading hole is connected with the outlet of threading hole, then the both ends of suture are passed through into extensor tendon stop, and
The upper end of extensor tendon stop is knotted, and extensor tendon stop is fixed on bone surface.But because suture knot is exposed in bone
Head surface, friction is easily produced, cause that knot is damaged, holdfast is fixed insecure, it is uncomfortable and be accompanied by inflammation to easily cause patient
Occur, cause healing slow.
The content of the invention
It is an object of the present invention to provide a kind of half-thread band line holdfast, and this kind band line anchor structure is simple, can more grasp
The property made with repeatability, without being knotted in bone surface, simplify surgical procedure, Post operation holdfast fix it is more firm, repair faster, hand
Postoperative effect is more preferable, has no adverse reaction.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of half-thread band line holdfast includes ground anchor body, and the ground anchor body lateral surface offers threaded portion, holdfast sheet
Internal portion, which is run through, offers threading hole so that rivet nut is hollow, reduces holdfast material usage.Dislocation offers on the threaded portion
Several cutout units, each cutout unit include the first excision face and the second excision face, the first excision face and second
It is in an angle between excision face.The setting of the threaded portion and cutout unit enables to ground anchor body to be preferably fixed in bone
Portion, there is the effect that anti-rotational, resistance to plucking goes out.Circulated in addition, threading hole and cutout unit are also convenient for liquid circulation in bone, be easy to soft group
Knit and quickly repair.
Angle between foregoing two neighboring cutout unit is 25 °~35 °.Bowed from the front end of ground anchor body or rear end
Depending on two neighboring cutout unit to the angular range formed between ground anchor body axle center is 25 °~35 °, and this kind of arrangement can
Ensure the intensity of ground anchor body, moreover it is possible to better ensure that its fastness, specific angle can be according to operative site and degree of impairment
Difference, it is adjusted.
Further, the ridge quantity that foregoing each cutout unit is crossed over up and down is one or two or three or four
It is individual.
Foregoing first excision face perpendicular to the outer surface of the threaded portion, the second excision face and the first excision face it
Between angle be 60 °~120 °.The presence of the cutout unit angle, it is easy to liquid circulation in Post operation bone to circulate, can also receives
The free bone bits of collection, are easy to bone uptake.
Foregoing threading hole is circular port or inner hexagonal hole, suitable for the fix tool of different size.If operation is planted
Enter position it is undesirable when, holdfast can also be back-outed by instruments such as plum blossom screwdrivers, have repeatability.
Foregoing threaded portion, the outer rim of cutout unit carry out rounding processing, reduce cutting of the edge to ligament, subtract
Damage in few surgical procedure to human body.
Beneficial, the front end of foregoing threaded portion is taper, and the taper is along from ground anchor body rear end to the holdfast
The direction area of body front end is gradually reduced, and reduces the resistance in surgical procedure, improves procedure efficiency.
Through there is suture in foregoing threading hole, the medical sutures knot after the completion of operation is placed in threading hole
Portion, no knot undercut mark are fixed, and the risk that knot is hit or released will not occur, and are avoided knotting in bone surface in the prior art and are made
Into abrasion, even the later stage produce inflammation hidden danger.
Suture is wound between the ridge groove of foregoing threaded portion, postoperative suture directly twines
It is wound between the ridge groove of threaded portion, without knotting, no knot undercut mark is fixed, and knot will not occur and hit or release
Risk, it is easy to preferably merge with human body.
The material of foregoing ground anchor body is PEEK materials, i.e. polyetheretherketonematerials materials, have good biocompatibility and
Enough initial fixing intensities, it is non-to can absorb but human body be caused to repel.The length of the ground anchor body is 10 ㎜~30
㎜, different size can be selected according to operative site and degree of impairment.This kind band line holdfast is widely used, available for rotator cuff injury
Repair, glenoid lip of articulation of humerus is repaired, nearly distal end brachial biceps are fixed, the repairing of knee joint collateral ligaments or reconstruction, kneecap are practised
The inertia dislocation bone surgery such as medial patellar retinaculum reefing or reconstruction, ligament of talocrural joint reparation or reconstruction.
Compared with prior art, the present invention is advantageous in that：
(1) this kind is a kind of anchoring piece that soft tissue is fixed to bone with line holdfast, without being knotted in bone surface so that hand
Postoperative holdfast fix more firmly, repair faster, Post operation effect it is more preferable, have no adverse reaction；
(2) setting of threading hole and cutout unit is easy to liquid circulation in bone to circulate, and can also collect free bone bits, convenient
Soft tissue is preferably repaired and and bone fusion；
(3) setting of threaded portion and cutout unit enables to ground anchor body to be preferably fixed on inside bone, have it is anti-rotational,
The effect that resistance to plucking goes out；
(4) front end of threaded portion is taper, reduces the resistance in surgical procedure, improves procedure efficiency；
(5) ground anchor body material is PEEK materials, i.e. polyetheretherketonematerials materials, has good biocompatibility and enough
Initial fixing intensity, it is non-to can absorb but human body be caused to repel；
(6) threading hole hole position can use particular design, such as inner hexagonal hole, if operation implantation position is undesirable, also
Holdfast can be back-outed by instruments such as hexagonal screwdrivers, it is simple to operate and with repeatability；
(7) hollow band string holes being offered in the middle part of ground anchor body, this kind of hollow design can also reduce rivet nut material usage,
Reduce cost.
