Description
Technical Field
The utility model relates to the technical field of orthopedic medical equipment, in particular to a Kirschner wire bending device special for orthopedics department.
Background
The kirschner wire is widely applied to surgical operations, the length of the kirschner wire is about twenty centimeters generally, the diameter of the kirschner wire is between 0.5 and 4 millimeters, and the kirschner wire is mainly used for assisting in resetting and fixing the parts of feet, hands, knees, ankles and the like, tension bands of elbows, fracture blocks of various joint surfaces and the like in orthopedic operations. Although the Kirschner wire provides a lot of convenience for fracture reduction and fixation, a plurality of complications exist, and the complications mainly comprise that the sharp tail end protrusion of the Kirschner wire irritates surrounding soft tissues and the Kirschner wire cannot be bent sufficiently and effectively for deep wounds due to the blocking of the surrounding soft tissues.
In an orthopedic operation, the fixation of a kirschner wire is often assisted to maintain the bone position, so that the fixation is convenient, and sometimes, the tail of the kirschner wire needs to be bent to be kept in a body. The existing Kirschner wire bending tool has the defects of consuming time and labor, being not sufficient in bending and being incapable of sufficiently and effectively bending the Kirschner wire in a deep wound, and if the Kirschner wire in the wound cannot be effectively bent, or the bending radian is too small, the tail part of the Kirschner wire stimulates the skin to cause pain or the tail part of the Kirschner wire has to be left outside the body and the like, which can influence the treatment effect of the Kirschner wire.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem among the prior art, the utility model provides a special ke shi needle bending machine of orthopedics has solved the inconvenient problem of ke shi needle of bending in current bone surgery.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:
the utility model provides a special ke shi needle bending machine of orthopedics, it includes and crosses the cylinder through the first cylinder of crossing and the second that tie-beam was fixed side by side, and the lower part that the cylinder was crossed to first cylinder of crossing and second all is provided with the conical surface, and the minor diameter end of conical surface is the arc surface and flushes with the bottom face that cylinder was crossed to first cylinder of crossing and second, is fixed with the handle of bending on the tie-beam.
Furthermore, a first needle passing hole and a second needle passing hole are axially arranged on the first needle passing cylinder and the second needle passing cylinder respectively, and the aperture of the first needle passing hole is not equal to that of the second needle passing hole. The first needle passing cylinder and the second needle passing cylinder can bend the Kirschner wires with different specifications, and convenience is improved.
Furthermore, the taper range of the conical surface is 1: 3-1: 6. In the range of taper, the conical surface can be abutted against the bone of a patient when the Kirschner wire is bent, so that the bending process is easier and more labor-saving.
Further, the material of the first needle passing cylinder and the second needle passing cylinder is 304 stainless steel or 316 stainless steel. Both types of stainless steel are highly safe and allow insertion into a patient's wound after sterilization, improving ease and safety of handling.
Further, the bridge extends from the bottom end to the top end of the first and/or second needle passing cylinder. The integrity of the two needle passing cylinders is stronger, and the processing difficulty is reduced.
Furthermore, the bending handle is fixed on the middle lower part of the connecting beam.
Furthermore, the bottom end of the bending handle is fixed on the connecting beam and extends obliquely upwards, and the included angle between the bending handle and the axis of the first needle passing cylinder or the second needle passing cylinder is 25-40 degrees. The bending handle in the angle range is most labor-saving when the Kirschner wire is bent, the bending difficulty is reduced, and meanwhile, when the Kirschner wire positioned in a deep wound is bent, the included angle between the bending handle and the axis of the first needle passing cylinder or the second needle passing cylinder is 25-40 degrees, so that the blocking effect of surrounding soft tissues can be reduced.
Furthermore, the bending handle comprises a handle part and a connecting rod for connecting the handle part to the connecting beam, and anti-skidding grains are arranged on the handle part. The friction force between the hands of the operator and the handle part is increased through the anti-slip lines, so that slipping is prevented, and the safety and the reliability are improved.
Furthermore, the connecting rod is S-shaped, the outer surface of the connecting rod is smooth, the appearance is more attractive, and the length of the bending handle is at least 6 times of that of the first needle passing cylinder or the second needle passing cylinder, so that labor is saved during bending.
The utility model has the advantages that: when the Kirschner wire needs to be bent, the Kirschner wire is inserted into the first needle passing cylinder or the second needle passing cylinder, the bending handle is held to be lifted or pressed downwards, the needle passing cylinder drives the bending end of the Kirschner wire to be bent, and the Kirschner wire is bent by extruding the inner edge of the bottom end of the needle passing cylinder on the Kirschner wire.
The two needle passing cylinders are arranged to bend the Kirschner wires with two different specifications, so that when two Kirschner wires are used in the same operation, the bending instruments do not need to be replaced, the number of the instruments is reduced, and the convenience in operation is improved. The two needle passing cylinders are connected into a whole through the connecting beam, so that the whole performance of the needle passing cylinders is better, and the strength is higher.
The conical surface of crossing setting up on the cylinder makes to cross the cylinder and can be pushed deep wound in, and the path end of conical surface makes the soft tissue on pushing in-process wound pushed away naturally for the arc surface, has avoided crossing the cylinder and has bent the soft tissue on the in-process extrusion wound, causes further injury to the conical surface is the surface of revolution, has also avoided leading to the fact secondary damage pushing to have sharp-pointed structure in-process of crossing the cylinder. The Kirschner wire can not be effectively bent due to the fact that the Kirschner wire is blocked by soft tissues around the wound in the bending process, the Kirschner wire can be rotated to the direction which can be fully bent to be bent by rotating the bending handle, and therefore the fact that the needle cylinder can effectively bend the Kirschner wire in the deep wound is guaranteed, pain caused to the patient by the Kirschner wire is reduced, and the exposed part of the Kirschner wire is reduced.
The bending handle fixed with the connecting beam is long in length, and compared with a needle cylinder which is directly pulled, the limiting of the insertion function of the kirschner wire for the needle cylinder is avoided, so that the length of the power arm during bending is increased, and the purpose of saving labor is achieved.
