Abstract

The utility model relates to a wire tightener used in orthopaedics, which comprises a first tightening arm, a second tightening arm and a transverse lever. The rear ends of the first tightening arm and the second tightening arm are articulated with the transverse lever respectively; a hand lever is also included; a head of the hand lever passes through the transverse lever; the hand lever and the transverse lever are in threaded connection; the first tightening arm is connected with the head of the hand lever through a first stay bar; the second tightening arm is connected with the head of the hand lever through a second stay bar; the first tightening arm is symmetrical to the second tightening arm, and the first stay bar is symmetrical to the second stay bar; both the first tightening arm and the second tightening arm are provided with downwards concave parts; a threaded rod passes through the downwards concave parts; a threading hole is formed on the threaded rod, and a fastening nut is arranged on the threaded rod in a screwing manner; both the front ends of the first tightening arm and the second tightening arm are threading ports; and the threading ports extend backwards to form a threading channel. The wire tightener used in orthopaedics is specially used for tightening wires in bone surgery, and is simple and convenient to operate.

Description

Orthopaedics cable tightener

(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: orthopaedics cable tightener, comprise that first tightens up arm, second and tighten up arm and cross bar, and described first tightens up arm and second, and to tighten up the rear end of arm hinged with described cross bar respectively; Also comprise one handle, the head of described handle passes described cross bar, be threaded between this handle and the described cross bar, described first tightens up between the head of arm and described handle and is connected by first strut, and the two ends of described first strut are respectively with described first to tighten up the head of arm and handle hinged; Described second tightens up between the head of arm and described handle and is connected by second strut, and the two ends of described second strut are respectively with described second to tighten up the head of arm and handle hinged; Described first tightens up arm and second, and to tighten up arm symmetrical, and described first strut and second strut are symmetrical; Described first tightens up arm and second tightens up arm and all has lower concave part, 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 first tightens up arm and second front end that tightens up arm is threading opening, and this threading opening extends back and forms the threading passage, and described threading passage extands rearward in the lower concave part in described screw rod the place ahead.

Further, the centrage of described threading passage rear end and the centrage of the through wires hole on the described screw rod are positioned on the same axis.

Further, the head of described handle is arranged with back cover, puts after described and offers form, and described form is provided with scale.

This utility model in use, cable passes threading opening successively, through wires hole on threading passage and the screw rod, then clamp nut is tightened, thereby cable is compressed, turning handle makes and retreats then, and handle drives first strut and second strut pulling first and tightens up arm and second and tighten up arm and close up, 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.

Fig. 2 is the partial enlarged drawing of A part among Fig. 1.

(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, Fig. 2, orthopaedics cable tightener comprises that first tightens up arm 1, second and tighten up arm 2 and cross bar 3, and described first to tighten up rear end that arm 1 and second tightens up arm 2 hinged with described cross bar 3 respectively;

Also comprise one handle 4, the head of described handle 4 passes described cross bar 3, is threaded between this handle 4 and the described cross bar 3.Described first tightens up between the head of arm 1 and described handle 4 and is connected by first strut 5, and the two ends of described first strut 5 are respectively with described first to tighten up the head of arm 1 and handle 4 hinged; Described second tightens up between the head of arm 2 and described handle 4 and is connected by second strut 6, and the two ends of described second strut 6 are respectively with described second to tighten up the head of arm 2 and handle 4 hinged.

Described first tightens up arm 1 and second, and to tighten up arm 2 symmetrical, and described first strut 5 and second strut 6 are symmetrical.

Described first tightens up arm 1 and second tightens up arm 2 and all has lower concave part 7, is equipped with screw rod 8 on the described lower concave part 7, offers on the described screw rod 8 that spiral shell is provided with clamp nut 9 on through wires hole and this screw rod 8; Described first tightens up arm 1 and second front end that tightens up arm 2 is threading opening, this threading opening extends back and forms the threading path 10, described threading path 10 extands rearward in the lower concave part 7, and the end of threading path 10 is positioned at the place ahead of screw rod 8, and the centrage of described threading path 10 rear end and the centrage of the through wires hole on the described screw rod 8 are positioned on the same axis.

In use, cable passes threading opening successively, through wires hole on threading path 10 and the screw rod 8, then clamp nut 9 is tightened, thereby cable is compressed, turning handle 4 makes and retreats then, and handle drives first strut 5 and second strut 6 pulling first and tightens up arm 1 and second and tighten up arm 2 and close up, and cable can be tightened up.

In the present embodiment, the head of described handle 4 is arranged with back cover 11, offers form 12 on the described back cover 11, and described form 12 is provided with scale.Graduated meaning is set is and observes the information of tightening up of cable intuitively through form 12, thereby accomplish the degree of tightness appropriateness.
