Abstract
The utility model provides a metal cable belongs to the orthopedic medical devices field, and outside -in includes outer enhancement layer, middle filling layer and interior enhancement layer in proper order, and interior enhancement layer is formed by a plurality of soft metal silk twist, and middle filling layer comprises a plurality of soft metal silk layer, and adjacent soft metal silk layer is separated by a diaphragm, and outer enhancement layer is formed by the outer strengthen unit spiral winding of a plurality of. The utility model discloses metal cable simple structure, reasonable in design, easy operation can prevent that the soft metal silk from shifting and becoming flexible in the other direction, reduces the risk that the operation was implanted to the surgery to a certain extent, reduces clinical use's the degree of difficulty, more is favorable to shortening patient's the healing phase.
Description
Technical field
This utility model relates to orthopaedics medical instruments field, specifically a kind of metal cable cable.
Background technology
Metal cable cable is often used as treatment means in surgery implant surgery, but existing
Metal cable cable is formed by several cable unit twisteds mostly, but the tinsel of twisted is sometimes
There will be the opposite direction displacement along twisted or loosening phenomenon, so human body is carried out Srgery grafting operation
Time there is certain operation risk, add the difficulty of Clinical practice.Accordingly, it would be desirable to a kind of metal of exploitation
Cable cable, it is possible to prevent the displacement of Flexible wire opposite direction and loosen, reduces surgery to a certain extent and plants
Enter the risk of operation, reduce the difficulty of Clinical practice, be more beneficial for shortening the healing period of patient.
Summary of the invention
In view of this, this utility model aims to provide a kind of simple in construction, reasonable in design, simple to operate,
It is prevented from the displacement of Flexible wire opposite direction and loosens, reducing the wind of Srgery grafting operation to a certain extent
Danger, reduces the difficulty of Clinical practice, is more beneficial for shortening the metal cable cable of the healing period of patient.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that a kind of metal cable
Cable, ecto-entad includes outer enhancement Layer, intermediate filling layer and interior enhancement Layer, described interior enhancement Layer successively
Being formed by several Flexible wire twisteds, described intermediate filling layer is made up of several Flexible wire layers, institute
Stating adjacent Flexible wire layer by a membranes apart, described outer enhancement Layer is by several outer reinforcement unit spirals
It is entwined.
Further, described outer reinforcement unit is formed by several Flexible wire twisteds, and described outer reinforcement is single
The twisted direction of the Flexible wire of unit is in opposite direction with the twisted of the Flexible wire of interior enhancement Layer.
Further, the twisted direction of the Flexible wire of described outer reinforcement unit is clockwise, described
The twisted direction of the Flexible wire of interior enhancement Layer is counterclockwise.
Further, the twisted direction of the Flexible wire of described outer reinforcement unit is counterclockwise, described
The twisted direction of the Flexible wire of interior enhancement Layer is clockwise.
Further, described Flexible wire layer is four, five or six.
Further, the Flexible wire of a diameter of outer reinforcement unit of the Flexible wire of described interior enhancement Layer
5-8 times of diameter.
Further, the material of described Flexible wire be Ti-6Al-4V, Ti-6Al-7Nb, TA2, TA3,
00Cr18Ni14Mo3 or CoCrMo alloy.
Relative to prior art, this utility model has the advantage that
This utility model metal cable line structure is simple, reasonable in design, simple to operate, it is possible to prevent soft
Tinsel opposite direction shifts and loosens, and reduces the risk of Srgery grafting operation to a certain extent, and reduction is faced
The difficulty that bed uses, is more beneficial for shortening the healing period of patient.
Accompanying drawing explanation
