Abstract
The utility model relates to a medical fixing device, in particular to a tension band fixing device, comprising a steel cable and a steel needle. One end of the steel cable is provided with a buckle; an annular bump is arranged at the tail of the steel needle; the two sides of the annular bump are provided with a needle hole and a scale line, the scale line is close to the tail end of the steel needle, and the other side of the needle hole is provided with a ratchet; the buckle is sleeved on the front end of steel needle, and the other end of the steel cable perforates through the needle hole. Compared with the prior art, the utility model employing the technical scheme has the advantages of simple structure, convenient manufacturing, high intensity and good toughness; the steel needle can be inserted into a tail ring of the steel cable, the steel cable also can be inserted into a hole of the steel needle for rotating, pressurizing and fixing; the steel needle and the steel cable can be tightly coiled to be integrally fixed with the bone without loosening; the steel cable and the steel needle are coiled and pressurized, which is stronger than the screw pressurizing force, and is more difficult to be broken; and the steel needle and the bone are fixed integrally.
Description
Technical field:
This utility model relates to a kind of medical fixture, particularly a kind of tension band fixture.
Background technology:
In the process of fracture tension band internal fixation, steel wire and draw point more often are used.And clinical used steel wire is a sub-thread, and matter is hard, and pliability is poor.Draw point is a single-column shape structure, and anti-rotation and phorogenesis are poor, and can not firmly be connected with steel wire, cause some operation techniques to be restricted.And be with cutting pliers steel wire to be twisted clinically in the process of tension band internal fixation, the elasticity of steel wire is difficult to grasp, the pressurization weak effect, and brute force is twisted into two parts steel wire when tightening steel wire and pressurizeing easily, influences operation technique.If tighten reluctantly, also be easy to loosening during afterwards functional exercise or fracture the healing of influence fracture.And steel wire is at the docile and obedient weak effect of bone surface.The loosening easily slippage of steel wire, even break away from, to operative failure.
The utility model content:
Provide but goal of the invention of the present utility model is to overcome the deficiency of background technology a kind of draw point and wirerope compact winding and with skeletal fixation be the tension band fixture of one.
This utility model adopts following technical scheme:
A kind of tension band fixture comprises wirerope, draw point, one end of described wirerope is provided with latch closure, and the afterbody of described draw point is provided with circular protrusion, and the both sides of this circular protrusion are respectively equipped with pin hole and line of weakness, this line of weakness is near the tail end of draw point, and the opposite side of described pin hole is provided with ratchet; Described latch closure is sleeved on the front end of draw point, and the other end of this wirerope passes described pin hole.
This utility model that adopts technique scheme compared with prior art, its advantage is: simple in structure, easy to make, intensity height, good toughness, draw point can insert in the tail ring of wirerope, the hole that wirerope also can insert draw point and be rotated the fixed operation of pressurization; But draw point and wirerope compact winding, with skeletal fixation be one, can not occur becoming flexible; Wirerope and draw point are to twine pressurization, promptly by the unidirectional rotation of draw point, the wirerope compact winding on draw point, are played pressurization, and be more powerful than tightening pressure force, frangibility more not, and making draw point and skeletal fixation is one.
As a kind of preferred version of the present utility model, described wirerope is the structure that the steel wire strand braiding constitutes.
As a kind of preferred version of the present utility model, described latch closure is to connect and fixed structure in the wirerope body behind the wirerope one end fold back.
As a kind of preferred version of the present utility model, the outer diameter of described pin hole is greater than the diameter of described draw point.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is result of use figure of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples in detail this utility model is described in detail:
A kind of tension band fixture is referring to accompanying drawing 1 and accompanying drawing 2, among the figure: draw point 1, latch closure 2, wirerope 3, ratchet 4, circuitous portion 5, pin hole 6, circular protrusion 7, line of weakness 8, bone drill 9, ratchet slot 10, patella 11, fracture line 12.
In the present embodiment, an end of wirerope 3 is provided with latch closure 2, and the afterbody of draw point 1 is provided with prominent 7 of ring-type, and the both sides of circular protrusion 7 are respectively equipped with pin hole 6 and line of weakness 8, and line of weakness 8 is near the tail end of draw point 1, and the opposite side of pin hole 6 is provided with ratchet 4; Latch closure 2 is sleeved on the front end of draw point 1, the other end of wirerope 3 with pass pin hole 6 back and form circuitous portions 5 and be intertwined and connected with the wirerope trunk.
The structure that wirerope 3 constitutes for the steel wire strand braiding, the finer wire of its other end is welded as a whole, and the thin steel wire that can avoid constituting wirerope hangs down loosely.Latch closure 2 is to connect and fixed structure in the wirerope body behind the wirerope 3 one end fold backs.
In order to improve the bulk strength of draw point 1, the outer diameter of pin hole 6 is greater than the diameter of draw point 1.
Ratchet 4 in the present embodiment can only unidirectional rotation in ratchet slot 10, the unidirectional rotation of ratchet 4 may command draw points 1.
In patella 11 fracture internal fixation operations, the at first reduction of the fracture, slot with bone drill 9 in patella 11 1 side draw points 1 entry point place, the ratchet slot of opening 10 is slightly less than ratchet 4, with bone drill 9 draw point 1 its main body is squeezed in the patella 11 then, reach the edge of ratchet slot 10 to ratchet 4, run through fracture line 12, the latch closure 2 of wirerope 3 is inserted in draw point 1 far-end, wirerope 3 its main bodys through patella 11 front sides to draw point 1 front end, wirerope 3 is passed pin hole 6, form a circuitous portion 5 behind wirerope 3 fold backs and twine and tension with the wirerope main body again; Unnecessary wirerope 3 usefulness cutting pliers are cut off, then with bone drill 9 by with the opposite spin draw point 1 of ratchet 4 openings, make wirerope 3 compact winding on the draw point 1 between pin hole 6 and the annular projection 7, treat in line of weakness 8 places draw point 1 to be fractureed after fracture end closely pressurizes, draw point 1 far-end redundance is cut off with cutting pliers and is got final product.
