The electric drill for tying up operation twists tight device with steel wire comprising electric drill connector 1, extension rod 2 and steel wire end connection component 3.Electric drill connects
Connector 1 and extension rod 2 are substantially cylindrical, and multiple concaveconvex structures can be equipped on 1 cylinder of electric drill connector, connect for relatively fixed
Connect the bone surgery electric drill to match with the concaveconvex structure shape.One end of extension rod 2 is fixedly connected with electric drill connector 1, steel
Silk end connection component 3 is set on extension rod 2, for being attached with steel wire.In use, electric drill twists tight device with steel wire
Collocation and the 1 matched electric drill of outer cylinder face shape of electric drill connector, the steel wire both ends for tying up bone block are respectively penetrated and are wound into two
It is not fastened in a steel wire end connection component 3, the twirl that steel wire can be completed in starting electric drill fastens work.
Fig. 1 and Fig. 2 are please referred to, in a preferred embodiment, each steel wire end connection component 3 includes at least three along extension rod
The prominent bar 31 of 2 axially spaced-aparts setting, dashing forward bar 31 can be cylindrical, and the ratio between the length of cylinder and the radius of cylinder can be 5-7:1, i.e.,
When the radius of cylinder is 0.5 centimetre, the length of cylinder corresponds to 2.5 centimetres to 3.5 centimetres.Referring to FIG. 1, being prolonged with cylindric
The axial direction of boom 2 is longitudinal direction, then the radial direction of extension rod 2 is transverse direction, and bar 31 of dashing forward is laterally prominent relative to extension rod 2
Out, i.e., prominent bar 31 is prominent with the radial direction of extension rod 2.It is said it should be noted that above-mentioned longitudinal direction and transverse direction are only used for combining
Bright book attached drawing carries out the explanation of structure, without influencing the utility model embodiment in the structure setting of other embodiments.
Tightly operated for the ease of the twirl of electric drill, suitable for the spacing between 31 length of prominent bar and prominent bar 31 of winding steel wire it
Than that can be 1.2-1.6:1, i.e., when the spacing between prominent bar 31 is 2 centimetres, the length of prominent bar 31 corresponds to 2.4 centimetres to 3.2
Centimetre.It should be noted that the spacing be expressed as on a prominent bar a little to phase same point on adjacent prominent bar linear distance.
In other embodiments, each steel wire end connection component 3 can also be suitable for steel wire for multiple annular shapes, strip etc.
The shape of winding or connection, each shape are arranged along 2 axially spaced-apart of extension rod.The spacing at the interval between each shape and its
The length ratio of shape may be 1:1.2-1.6.
Referring to FIG. 1, for the ease of two groups of steel wire end connection components 3 of steel wire winding, it is ensured that steel wire twists tight uniform, two steel
The prominent bar 31 of silk end connection component 3 is separately positioned on the opposite sides of extension rod 2, and two the multiple of steel wire end connection component 3 dash forward
