Abstract
The invention relates to a suture anchor which comprises a suture anchor body, a thread part, a threading structure and a stress structure, wherein the thread part is arranged at the exterior of the suture anchor body; the threading structure is arranged on the suture anchor body; the stress structure is arranged on the suture anchor body; the thread part is of a thread structure distributed in a high-low manner. By virtue of the thread structure distributed in a high-low manner, the thread structure has stronger anti-pull capacity than a common thread structure; during a process of screwing into a bone, the screwing torque can be reduced, so that not only can medical operation be facilitated, but also pains of patients are reduced; furthermore, the effect of the bone fixation is good, the suture anchor is difficult to loose, secondary injury of the patients is avoided. The invention also relates to a handle matched with the suture anchor, and the handle is simple to use and convenient to install and dismount.
Description
Technical field
The present invention relates to the surgery fixing nail technical field of a kind of sewing-up cut, be specifically related to a kind of band
Line holdfast and handle thereof.
Background technology
When soft tissue tears off from bone and needs to repair, it usually needs surgeon's suture
Repairing and separate soft tissue, suture is attached to bone by band line holdfast.Wherein, soft tissue is easy
From the position that bone tears off typically at shoulder joint, knee joint, hip joint etc..During use, band line anchor
The implanted bone of point, suture, then will with suitable tension force through the soft tissue to be again attached
Suture is fixed on band line holdfast, to reach the purpose of tendon-knitting.
Band line holdfast of the prior art generally comprises holdfast main body and sets in described holdfast main body
It is equipped with screw thread, in described holdfast main body, is provided with threading structure and force structure, such as China simultaneously

ZL201120453948.4, ZL201420245554.3 disclose several structures of band line holdfast,
Being substantially all that to include or arrange be exactly said structure, wherein, described threading structure is exactly suture
Through the concrete structure of described band line holdfast, such as thimble, Wire channel in building, through wires hole etc., and described
Cooperation force application structure that force structure is provided in described band line ground anchor body (or it is handle,
For described band line holdfast being implanted or being screwed into bone) described band line holdfast is fixed on bone
Concrete structure, internal thread in band line holdfast intermediate throughholes as described in be arranged on, inner hexagonal hole groove etc..
Said structure can pass through helicitic texture and combine force structure and force application structure by described band
Line holdfast is implanted or is screwed into bone, but, described helicitic texture is usually full thread structure, easily
When implanting or being screwed into bone, skeleton is damaged, make patient or the wounded easily be formed
Secondary injury, for this, people never finds good solution.
Summary of the invention
To this end, the technical problem to be solved is the full spiral shell of the band line holdfast of prior art
The phenomenon that skeleton is easily damaged by line structure when implanting or being screwed into bone, and then make
The problem that patient or the wounded easily form secondary injury.
For solving above-mentioned technical problem, the invention provides a kind of band line holdfast, comprising:
Band line ground anchor body；
Threaded portion, described threaded portion is arranged on the outside of described band line ground anchor body；
Threading structure, is arranged in described band line ground anchor body；
Force structure, is arranged in described band line ground anchor body；
Described threaded portion is the helicitic texture of height arrangement.
Preferably, described threaded portion includes two screw threads, and the highest screw thread and low thread are described
High screw thread and the height uniform intervals arrangement of described low thread.
Further, described force mechanism is the cylinder being arranged on described band line ground anchor body end.
Further, described threading structure is the through hole being arranged on described cylinder.
Along described cylinder axial direction, described damaged surface is provided with first from described through hole two ends
Wire casing.
The present invention also discloses a kind of handle, its with band line holdfast described above with the use of,
Including:
Handle；
Ducted body, one end of described ducted body is connected setting with described handle, and the other end formed with
The inner prop body opening that described cylinder coordinates.
Described handle is provided with a through hole, and one end sleeve is located on described ducted body, and with
Described ducted body is fixed together, and meanwhile, is provided with the second wire casing on described handle the other end.
Side-wall outer side at described handle is provided with at least one projection, and the side of described second wire casing
Described projection is pointed to by described through hole.
Further, briquetting, stopper and spring are also included；It is provided with connection on described handle to be arranged on
Together at hand, briquetting sleeved part and stopper connecting portion；Described briquetting and described briquetting sleeved part
Being formed with spring and accommodate space, described spring is within described spring accommodates space and is set in described pressure
In block sleeved part, and it is provided with stress unit on described briquetting；Described stopper is connected with described stopper
Portion connects setting, and makes the one end of described briquetting be resisted against the one end of described stopper, and described
Gap cavity it is provided with in stopper.
Preferably, described briquetting sleeved part is provided with at least one groove, at described briquetting
The sliding shoe matched with described bar groove it is provided with on relevant position；Described stopper is with described stopper even
The portion of connecing is connected together.
The technique scheme of the present invention has the advantage that compared to existing technology
(1) the band line holdfast of the present invention, including: band line ground anchor body；Threaded portion, described spiral shell
Line portion is arranged on the outside of described band line ground anchor body；Threading structure, is arranged on described band line holdfast
On body；Force structure, is arranged in described band line ground anchor body；Described threaded portion is height arrangement
Helicitic texture.By arrange height arrangement helicitic texture, above-mentioned helicitic texture can ratio typically
Helicitic texture resistance to plucking output capacity strong, and when being screwed into bone, can reduce and be screwed into torsion, both facilitate
Doctor operates, and reduces again patient suffering, and meanwhile, fixing bone is effective, makes affiliated band line holdfast
It is not easy to loosen, it is to avoid patient's second hurt.
(2) the band line holdfast of the present invention, described threaded portion includes two screw threads, the highest spiral shell
