Detailed Description
The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.
The invention relates to an orthopedic implant nail guiding and locking device, which is used for treating limb trauma fracture and the like.
Fig. 1 shows a structural view of an orthopedic implant nail guide locking device of the present invention. As shown in fig. 1, the orthopedic implant nail guide locking device of the present invention comprises an arc-shaped locking plate 1, similar to the prior art. Wherein the inner concave surface of the arc-shaped locking plate 1 is attached to the patient's bone (e.g., lower leg, arm, etc.). The locking plate 1 is provided with a plurality of through holes 2. The through hole 2 is used for the implantation nail to pass through. A guide mechanism 3 is arranged around each of the through holes 2 and the guide mechanism 3 is arranged on the outer convex surface of the locking plate 1. The guide mechanism 3 is used to guide and fix the implant pin.
Preferably, the locking plate 1 is made of steel plate. Therefore, the bone and the like of the patient can be better fixed, and the rehabilitation of the patient is more facilitated.
Unlike the prior art in which the guide post and the locking plate are integrally formed, in the present invention, the guide mechanism 3 is connected to the outer convex surface of the locking plate 1 by a ball and socket connection structure. In this way, the guide mechanism 3 can be angularly adjusted with respect to the locking plate 1, thereby adjusting the implantation angle of the implantation nail.
In particular, as shown in fig. 1 and 2, the locking plate 1 is provided with a connecting socket 1.1 on the outer convex surface. And, two sides of each perforation 2 are respectively provided with one connecting nest 1.1. Meanwhile, the guide mechanism 3 includes two connecting balls 3.1, two connecting cylinders 3.2, two connecting rods 3.3, and two springs 3.6.
Wherein, one connecting ball 3.1 is arranged in each connecting socket 1.1 to form the ball-and-socket connecting structure. Each of the connecting balls 3.2 is connected to one end of one of the connecting cylinders 3.2. The other end of the connecting cylinder 3.2 is inserted with one end of the connecting rod 3.3. The spring 3.6 is arranged in the connecting cylinder 3.2. One end of the spring 3.6 is connected with the inner side of the one end of the connecting cylinder 3.2, and the other end is connected with the one end of the connecting rod 3.3. In this way, the connecting rod 3.3 and the connecting cylinder 3.2 can be moved relative to each other, so that the height of the guide mechanism can be adjusted.
The other ends of the two connecting rods 3.3 are connected with the lower end of the guide post 3.4. And a threaded hole 3.5 matched with the implantation nail is formed in the guide post 3.4.
In the present invention, preferably, the locking plate 1 is further provided with a first strap 4 and a second strap 5 which cooperate with each other to bind the locking plate 1 to the patient. In this way, the locking plate 1 is easily tied to the patient by the first and second straps 4 and 5, thereby further achieving fixation thereof.
More preferably, a plurality of first permanent magnets 6 are provided on the first strap 4. The second binding band 5 is provided with a plurality of second permanent magnets 7. And, the first permanent magnet 6 is opposite in magnetism to the second permanent magnet 7. In this way, the locking plate 1 can be easily bound to the patient by the magnetic attraction between the first permanent magnet 6 and the second permanent magnet 7, so that the operation is simpler and more convenient.
Still preferably, three first straps 4 and three second straps 5 are provided on the locking plate 1. Most preferably, three of said first straps 4 and three of said second straps 5 are evenly spaced on said locking plate 1. In this way, a more secure fixation of the locking plate 1 on the patient can be ensured.
Also, in the present invention, it is preferable that the first and second bands 4 and 5 are made of cotton cloth. This makes the patient more comfortable when strapped to the patient.
Furthermore, in the present invention, it is preferable that the diameter of the through hole 2 is larger than the diameter of the screw hole 3.5. More preferably, the diameter of the through hole 2 is 2-3 times the diameter of the threaded hole 3.5. In this way, it is also ensured that an implant nail can be inserted through the through-hole 2 and into the patient when the guide mechanism 3 is tilted with respect to the locking plate 1.
In use, the locking plate 1 is placed on an injured limb (e.g. an arm or lower leg) of a patient such that the concave inner surface of the locking plate 1 conforms to the limb of the patient. Thereafter, the locking plate 1 is bound to the limb of the patient by means of the first and second straps 4, 5 by means of the combination of the first and second permanent magnets 6, 7. Then, the angle of the guide mechanism 3 relative to the locking plate 1 is adjusted by means of the ball-and-socket connection structure according to the injured condition, the bone condition and the like of the patient, and after the angle adjustment is proper, an implantation nail is implanted into the patient through the threaded hole 3.5 and the perforation 2. During the implantation process, the implantation depth of the implantation nail is determined according to the injury condition, the orthopedic condition and the like of a patient. Because a spring 3.6 is arranged between the connecting rod 3.3 and the connecting cylinder 3.2, the height of the guide mechanism 3 can be adjusted, and the implantation depth of the implantation nail can be adjusted.
The guide mechanism of the orthopedic implant nail guide locking device is connected with the locking plate through the ball-and-socket connecting structure, so that the angle of the guide mechanism can be adjusted relative to the locking plate, implant nails can be arranged at different angles according to different patients, and a better treatment effect can be achieved. Simultaneously, through set up spring etc. in guiding mechanism for guiding mechanism's height can automatically regulated, thereby makes the implantation depth that can adjust the implantation nail, has satisfied the demand that same kind implantation nail can be used for different patients, has increased the commonality of apparatus, has reduced patient's economic burden. Finally, the binding belts are connected through the magnets, so that the binding is very simple, the disassembly and the binding are convenient, and the use is very convenient.
The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes and modifications which are obvious to the technical scheme of the invention are covered by the protection scope of the invention.
