Abstract
The utility model relates to a wire tightener used in orthopaedics, which is characterized in that a cannula, a rear sleeve and a hand lever are included; a tail-end of the cannula extends into the rear sleeve from the front end of the rear sleeve; the hand lever extends into the rear sleeve from the rear end of the rear sleeve; the cannula is fixedly connected with the hand lever in threaded connection with the inner wall of the rear sleeve; the cannula is provided with a downwards concave part positioned in front of the rear sleeve; a threaded rod passes through the downwards concave part; a threading hole is formed on the threaded rod, on which a fastening nut is arranged in a screwing manner; a threading port is arranged at the front end of the cannula; and a threading channel that backwards extends to the downwards concave part of the cannula in front of the threaded rod is arranged inside the cannula. The wire tightener used in orthopaedics is specially used for tightening wires in bone surgery, and is simple and convenient to operate.
Description
(1) technical field
This utility model relates to a kind of orthopaedics cable tightener.
(2) background technology
When carrying out bone surgery, often to use orthopaedics steel wire, cable etc. and bundle operation.In the prior art, cable tighten up the device that does not have a kind of special use, therefore carry out extremely bothering when cable tightens up operation.
(3) summary of the invention
In view of the orthopaedics cable tightener that does not still have at present special use, this utility model provides a kind of orthopaedics cable tightener that cable tightens up that carries out when being exclusively used in bone surgery.
The technical scheme in the invention for solving the technical problem is: a kind of orthopaedics cable tightener, comprise sleeve pipe, back cover and handle, described telescopic afterbody stretches in this back cover from the front end of described back cover, and described handle stretches in this back cover from the rear end of described back cover; Described sleeve pipe and described handle are affixed, and described handle overlaps between the inwall with described back and is threaded; Described sleeve pipe has the lower concave part that is positioned at described back cover the place ahead, is equipped with screw rod on the described lower concave part, offers on the described screw rod that spiral shell is provided with clamp nut on through wires hole and this screw rod; Described telescopic front end is a threading opening, has the threading passage of the sleeve pipe lower concave part that extands rearward to described screw rod the place ahead in the described sleeve pipe.
Further, the centrage of the through wires hole on the centrage of this threading passage and the described screw rod is positioned on the same axis.
Further, put after described and offer form, described form is provided with scale.
This utility model in use, cable passes threading opening successively, the through wires hole on threading passage and the screw rod is tightened clamp nut then, thereby cable is compressed, turning handle then drives sleeve pipe by handle and retreats and cable can be tightened up.
The beneficial effects of the utility model are: provide a kind of and carried out the orthopaedics cable tightener that cable tightens up when being specifically designed to bone surgery, and easy and simple to handle.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
With reference to Fig. 1, a kind of orthopaedics cable tightener comprises sleeve pipe 1, back cover 2 and handle 3, and the afterbody of described sleeve pipe 1 stretches in this back cover 2 from the front end of described back cover 2, and described handle 3 stretches in this back cover 2 from the rear end of described back cover 2; Described sleeve pipe 1 and described handle 3 are affixed, and described handle 3 overlaps between 2 inwalls with described back and is threaded; Described sleeve pipe 1 has the lower concave part 4 that is positioned at described back cover 2 the place aheads, is equipped with screw rod 5 on the described lower concave part 4, offers on the described screw rod 5 that spiral shell is provided with clamp nut 6. on through wires hole and this screw rod 5
The front end of described sleeve pipe 1 is a threading opening, has the threading passage 7 that extands rearward to described telescopic lower concave part 4 in the described sleeve pipe 1, and the end of this threading passage 7 is positioned at the place ahead of described screw rod 5, and the centrage of the through wires hole on the centrage of this threading passage 7 and the described screw rod 5 is positioned on the same axis.In use, cable passes threading opening successively, and the through wires hole on threading passage 7 and the screw rod 5 is tightened clamp nut 6 then, thereby cable is compressed, and turning handle 3 then, drives sleeve pipe 1 by handle 3 and retreats and cable can be tightened up.
In the present embodiment, offer form 8 on the described back cover 2, described form 8 is provided with scale, graduated meaning is set is and can observes the information of tightening up of cable intuitively through form 8, thereby accomplish the degree of tightness appropriateness.
