Detailed Description
Referring to fig. 1 to 6, the steel wire fastener for orthopedic surgery of the present invention includes an outer sleeve 1, an inner sleeve 2 and a steel wire lifting device 3;
as shown mainly in fig. 2, one end of the outer sleeve 1 is a closed end 11, the other end is an open end 12, and the inner wall of the outer sleeve 1 is provided with internal threads 12; the outer surface of the closed end 11 is a circular arc surface so as to prevent the outer sleeve 1 from scraping and damaging the hand of the operator.
As shown mainly in fig. 3 and 4, the inner end 21 of the inner sleeve 2 is sleeved in the outer sleeve 1 and is provided with an external thread 23, and is connected with the outer sleeve 1 through the internal thread 12 and the external thread 23, and the outer end 22 of the inner sleeve 2 is provided with an end opening 24 and a lateral operation window 25; the end opening 24 is divided into two inlets 242 by a T-shaped parting strip 26, so that two steel wires can be knotted at the T-shaped parting strip 26 by a tool such as pliers after the two steel wires respectively extend from the inlets 242, and the operation is particularly convenient. The lateral operating window 25 occupies half the area of the circumference of the inner sleeve leaving a semi-cylindrical configuration, which leaves more of the inner part of the inner sleeve 2 open and thus allows a larger operating space for the operation. The tail end of the outer end 22 of the inner sleeve 2 tapers from inside to outside, which occupies a small space and facilitates fine manipulation when inserted into a patient. The inner sleeve is further provided with feet 27 on each side of the end of the outer end thereof, so that the compression can be carried out by the feet against the patient's bone.
As shown in fig. 1, 5 and 6, the steel wire pulling device 3 is inserted into the inner sleeve 2, one end of the steel wire pulling device is fixedly connected to the closed end 11 of the outer sleeve 1, and the other end of the steel wire pulling device is provided with a hook 322, and the hook 322 corresponds to the lateral operation window 25. Specifically, the steel wire lifting device consists of a rotating rod 31 and a hook part 32; one end of the hook part 32 is provided with a groove 321, and the other end is provided with the hook 322; one end of the rotating rod 31 is fixedly connected to the closed end 11 of the outer sleeve 1, and the other end of the rotating rod is rotatably connected to the groove 321 of the hook portion 32, so that when the outer sleeve 1 is rotated to drive the rotating rod 31 to rotate, the hook portion 32 can be kept from rotating, and thus, a steel wire hung at the hook 322 cannot be twisted into one strand to hurt a patient.
As shown in fig. 6, the hook 322 is formed by bending an edge of a flat plate. Preferably, a guide plate 323 extends from each of two sides of the hook 322, and the presence of the guide plate 323 reduces damage caused by a large shearing force applied to the steel wire by the edge of the hook.
In addition, the outer sleeve 1, the inner sleeve 2 and the steel wire lifting device 3 are all made of high-quality stainless steel, so that on one hand, enough strength can be ensured, and on the other hand, the steel wire lifting device can be repeatedly used through high-temperature and high-pressure sterilization.
The working principle and the operation process of the invention are as follows: the steel wires penetrate out from the two ends of the backbone, the two steel wires respectively penetrate into the two leading-in ports 242 of the end opening 24 at the outer end of the inner sleeve 2, the length is adjusted, the steel wire pliers are used for knotting on the T-shaped parting slip and then are placed on the hook 322 of the steel wire lifting device 3, the outer sleeve 1 is rotated according to the direction (such as anticlockwise) of the threads, the outer sleeve 1 is far away from the outer end 22 of the inner sleeve 2, the lifting device 3 is driven to be far away from the outer end 22 of the inner sleeve 2, and therefore the distance between the lifting device 3 and the outer end of the inner sleeve 2 is increased, and the steel wires are tensed. And then reversely rotating (for example, clockwise) the whole steel wire fastener to wind the two steel wires to form a steel wire knot, rotating the outer sleeve according to the direction of the thread (for example, clockwise) to loosen the steel wire, and cutting off the steel wire at the steel wire knot after reserving a certain length.
Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
