Abstract
The utility model discloses a titanium cable bundling system. A titanium cable is formed by entwisting 49 titanium wires. The diameter of the entwisted titanium cable is 2 mm. The lay length is fixed. The diameter of the titanium cable changes along with the requirement on tensile strength of the titanium cable in an operation. One end of the titanium cable is provided with a ball head which has a diameter larger than the diameter of each titanium cable penetrating hole. A titanium cable lock catch employs a trapezoid design to better achieve the objective of locking the titanium cable tightly. The length of the titanium cable lock catch is fixed to 9 mm. The two titanium cable penetrating holes of the cross section of the titanium cable lock catch are distributed uniformly on the cross section of the titanium cable lock catch. The diameter of each titanium cable penetrating hole changes along with the change of the diameter of the titanium cable. The diameter of each titanium cable penetrating hole is larger than the diameter of the titanium cable by 0.2 mm. A titanium cable adjusting lock catch locks the titanium cable tightly through a threaded jackscrew. The diameter of each titanium cable penetrating hole is larger than the diameter of the titanium cable by 0.2 mm.
Description
Technical field
This utility model relates to a kind of orthopaedics implant, and is particularly a kind of in when fracture, during the bone grafting plate, bone splits, steel plate fixedly the time for tying up fixing a kind of product
Background technology
Steel wire is as a kind of orthopedic fixer tool, and, spiral type oblique at tubular bone or have in the larger pulverizing osteocomma fracture has been widely used.Lose fixation but often causing because wire binding is insecure clinically slides, even slip into fracture end, cause bone does not connect also of common occurrence.If tie up tension, can cause steel wire fracture and lose fixation.How to make behind the wire binding that dynamics suitably and not can be slided, complication, become orthopedist's a difficult problem.So need at present a kind of new binding method to solve an above-mentioned difficult problem.
The utility model content
The purpose of this utility model is to provide a kind of mode of tying up safely and reliably for overcoming defects.
For achieving the above object, this utility model is taked following design:
Every titanium cable is made of 7 bunch, and every bunch is made of 7 strands again, so every titanium cable wrap contains 49 strands, is twisted with the fingers and is formed by 49 strands of titanium silks.Twist with the fingers with after titanium cable (1) diameter different diameters can be arranged as required, the lay pitch is regular length.The reinforcement that is straightened of every strand, multi cord are twisted into has good elasticity after a branch of, seems too hard and diameter is identical, draw the identical single steel wire of material when bending.The histocompatibility of titanium cable is good, avirulence has superior tensile strength and anti-fatigue life, and is fixing reliable and to insert human-body safety reliable, the foreign reaction, can stay in the body and to take out, remove again operation from, be equipped with the cable tensioner, reset with operation is simple and reliable, little to soft tissue injury in the art, avoided stress-shielding effect, meet the BO principle.One end of titanium cable has metal ball-head, and the bulb diameter is greater than the diameter in hole on the titanium cable snap close.Titanium cable snap close adopts trapezoidal design, can better reach the purpose of locking titanium cable, the length of titanium cable snap close is fixed length 9mm, wear titanium cable hole and be distributed on the titanium cable snap close cross section for two of titanium cable snap close cross section, the diameter of wearing titanium cable hole changes with the variation of titanium cable diameter, wears titanium cable bore dia than the large 0.2mm of titanium cable diameter.The titanium cable is regulated snap close and is adopted the mode of screw thread jackscrew that the titanium cable is locked, and wears the diameter in titanium cable hole than the large 0.2mm of titanium cable diameter.
The beneficial effects of the utility model are:
This utility model bifurcation design type prosthese, after adopting above design, the histocompatibility of titanium cable is good, avirulence, have superior tensile strength and anti-fatigue life, fixing reliable and to insert human-body safety reliable, the foreign reaction, can stay in the body and to take out, remove again operation from, be equipped with the cable tensioner, reset with operation is simple and reliable, little to soft tissue injury in the art, avoided stress-shielding effect, titanium cable snap close adopts trapezoidal design, can better reach the purpose of locking titanium cable, the titanium cable is regulated snap close can make things convenient for the kilogram number that utilizes at any time the cable tensioner titanium cable to be tightened to regulation, at any time locking.
This utility model design concept is advanced, simple in structure, has good application and market prospect in the orthopaedics art.
Below in conjunction with the drawings and specific embodiments this utility model is described in further details, present embodiment only is this utility model preferred forms, is not to restriction of the present utility model.
Description of drawings
Fig. 1 is the embodiment schematic diagram of this utility model titanium cable bounding system
Fig. 2 is titanium cable structure schematic diagram
Fig. 3 is that the titanium cable is regulated the buckle structure schematic diagram
The specific embodiment
As shown in Figure 2, this utility model titanium cable, every titanium cable is made of 7 bunch, and every bunch is made of 7 strands again, so every titanium cable wrap contains 49 strands, makes safety and reliability behind the implant into body.
And adopt the bulb design at far-end, one end can block bulb when the titanium cable passed titanium cable snap close via hole, and the other end, is conveniently tied up the tension of titanium cable with the cable tensioner.
As shown in Figure 3, the titanium cable is regulated snap close and is adopted the mode of screw thread jackscrew that the titanium cable is locked, and wears the diameter in titanium cable hole than the large 0.2mm of titanium cable diameter, makes things convenient for the titanium cable to pass, the titanium cable is regulated snap close can make things convenient for the kilogram number that utilizes at any time the cable tensioner titanium cable to be tightened to regulation, at any time locking.
