Technical Field

The utility model relates to the field of medical equipment, concretely relates to angle design bending machine.

Background

The kirschner wire is a commonly used internal fixation material for orthopedics, is a slender cylinder structure with a sharp end, and has several different specifications of 1, 1.2 and 1.5 millimeters in diameter. The device is used for fixing short fractures or avulsion fractures and other fractures with low stress. In order to prevent the sharp end of the Kirschner wire from stabbing soft tissues and displacing, the Kirschner wire needs to be bent. The bending step is carried out after most of the Kirschner wires are inserted into the bone.

the upper tong head and the lower tong head are hinged together through a hinge shaft;

the V-shaped protrusion is positioned on the inner side of the upper binding clip, and the V-shaped groove is positioned on the inner side of the lower binding clip opposite to the V-shaped protrusion;

the V-shaped protrusion is matched with the V-shaped groove.

Preferably, the number of the V-shaped protrusions and the number of the V-shaped grooves are multiple and the V-shaped protrusions and the V-shaped grooves are the same;

preferably, the angle between the V-shaped protrusion and the V-shaped groove is 30-90 degrees;

preferably, the angle between the V-shaped protrusion and the V-shaped groove is 60 degrees;

preferably, the number of the V-shaped protrusions and the number of the V-shaped grooves are 3;

preferably, the angles of the V-shaped protrusion and the V-shaped groove are respectively 30, 60 and 90 degrees.

The utility model is suitable for a 1.0-1.2-1.5mm kirschner wire, and iligarov external fixation frame combines the treatment fracture.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the utility model discloses simple structure carries out institutional advancement on vice or "orthopedics vice"'s basis, utilizes the extrusion design principle, according to V type protruding with angle is the same about the V type recess, pressurizes and moulds the type and reach the purpose of bending.

The design of base V type groove structure, can prevent that the kirschner wire from sliding, can realize bending to the different angles of kirschner wire.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

As shown in fig. 1-2, an angle-setting bender, comprising: the clamp comprises a V-shaped bulge 1, a V-shaped groove 2, an upper clamp head 3, a lower clamp head 4, a hinge shaft 5, a lower clamp handle 6 and an upper clamp handle 7; the upper tong head 3 is fixedly connected with the upper tong handle 7, and the lower tong head 4 is fixedly connected with the lower tong handle 6; the upper tong head 3 and the lower tong head 4 are hinged together through a hinge shaft;

the V-shaped protrusion 1 is positioned on the inner side of the upper binding clip 3, and the V-shaped groove 2 is positioned on the inner side of the lower binding clip 4 which is opposite to the V-shaped protrusion 1;

as shown in fig. 2, the V-shaped protrusion 1 is matched with the V-shaped groove 2, and the angles are the same, so that the kirschner wire can be bent at the same angle;

the number of the V-shaped protrusions 1 and the number of the V-shaped grooves 2 are respectively multiple, and the number of the V-shaped protrusions 1 is the same as that of the V-shaped grooves 2; the angles of the different V-shaped bulges and the different V-shaped grooves are different, and the angles of the V-shaped bulges and the V-shaped grooves are 30-90 degrees; the bending of the Kirschner wire at different angles can be realized;
