Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments for the treatment of fracture.Particularly a kind of multi-functional tibia intramedullary nail with lock.
Background technology:
At present, in the treatment to the fracture of tibia of human body, " tibia intramedullary nail with lock " is one of therapeutic device.Should " tibia intramedullary nail with lock " be that metallic is shaft-like.The end that " tibia intramedullary nail with lock " inserted behind the tibia towards knee is called near-end, is called far-end towards an end of heel; Respectively be provided with two locking nail holes at near-end and far-end, these four locking nail holes are the axis by " tibia intramedullary nail with lock " and being parallel to each other all.During use, " tibia intramedullary nail with lock " inserted in the tibia pulp cavity that fracture takes place with inserting device, pass locking nail hole and bone wall with pinning, " tibia intramedullary nail with lock " is fixed in the pulp cavity of fracture tibia, to avoid in therapeutic process, causing bone does not connect because of the fracture site swing; After treating that fracture site connects healing, again " tibia intramedullary nail with lock " taken out.
In order in the pulp cavity of tibia, to insert smoothly and fixing " tibia intramedullary nail with lock ", between the near-end of " tibia intramedullary nail with lock " and far-end, be provided with 12-15 ° bent angle, the plane that bent angle constitutes is vertical mutually with plane, four locking nail hole places; Be provided with the external device connecting device on the top of near-end; Distal tip is circular-arc inclined-plane, and this inclined-plane becomes 25 ° angle with the plane that locking nail hole constitutes.
Use " tibia intramedullary nail with lock " treatment fracture of tibia, because fracture site is supported and locatees, the patient has not only guaranteed the healing of tibia, and has reduced patient's misery through the walking of can leaving the bed ahead of time after treating.
But because 12 ° bent angle being provided with of present " tibia intramedullary nail with lock " close end, bent angle is excessive, in bad operation when the tibia pulp cavity inserts, and to the dissection bad adaptability of tibia, often causes the postoperative malreduction; Because four locking nail holes are on same and vertical plane, bent angle plane, distal tip does not have fixture, therefore, can't fracture down and anklebone fracture by the fixed tibial platform.
The utility model content:
This utility model aims to provide a kind of multi-functional tibia intramedullary nail with lock.It can insert more easily and be fixed in the tibia pulp cavity, to the dissection adaptability of tibia, avoids swinging the bone does not connect that causes because of the side in pulp cavity when improving treatment, and can treat fracture and anklebone fracture under the tibial plateau.
This utility model comprises main nail and pinning; Main nail is provided with bent angle for shaft-like between main near-end of following closely and far-end; On main near-end of following closely and far-end, respectively be provided with two horizontal locking nail hole A; The top of main nail near-end is provided with the external device connecting device; Main nail distal tip is circular-arc inclined-plane, and this circular-arc inclined-plane becomes 30 ° angle with the plane that locking nail hole A constitutes; It is characterized in that between the near-end of main nail and the far-end crooked 8 ± 3 °; Be provided with two locking nail hole C that intersect between the termination of main nail near-end and first locking nail hole A, two intersection locking nail hole C are vertical mutually, and the angle at 45 with locking nail hole A; Be provided with vertical with it locking nail hole B on the circular-arc inclined-plane of main nail distal tip, locking nail hole B is vertical mutually with locking nail hole A; Wherein, locking nail hole A is oval, and locking nail hole B and locking nail hole C are circular; Be threaded on the hole wall of locking nail hole C, as Fig. 1, shown in 2; In locking nail hole A and locking nail hole B, be equipped with the pinning that has the cortical bone screw thread, as shown in Figure 3; In locking nail hole C, be equipped with the pinning that has cancellous threads, as shown in Figure 4.
This utility model after the fracture site butt joint, will be led the pulp cavity that nail inserts tibia by inserting device in use, make its far-end towards heel, and near-end covers towards knee joint; It is fixing to lead nail with the pinning that has the cortical bone screw thread by tibial bone wall and locking nail hole A, locking nail hole B, it is further fixing to lead nail with the pinning that has cancellous threads by tibial bone wall and locking nail hole C, this utility model promptly plays support and fixation to the tibia through butt joint after the fracture, patient's walking of not only after treatment, can early leaving the bed, and guaranteed the healing of tibia.
The angle of this utility model crooked 8 ± 3 ° of these bent angles between main near-end of following closely and far-end is fit to the dissection of tibia more.Improve tibia and dissect adaptability, not only easy to operate, slotting people is smooth, and postoperative resets well.
This utility model is being led the locking nail hole C that the locking nail hole A near-end of following closely near-end is provided with two intersections, and the locking nail hole C of two intersections is vertical mutually, and the angle at 45 with locking nail hole A; The interior pinning that has cancellous threads that is equipped with of the locking nail hole C that intersects has overcome in the use and has swung the bone does not connect that causes because of the side of master's nail; And the fracture under can the fixed tibial platform.
This utility model is provided with the locking nail hole B of vertical direction on the circular-arc inclined-plane of main nail distal tip, and in locking nail hole B, be equipped with the pinning have the cortical bone screw thread, making the winner follow closely far-end can fix with the bone wall, not only improved the whole degree of stability of main nail, and, can fix and treat the fracture of anklebone.
Locking nail hole A of the present utility model is oval, when main nail inserts the tibia of human body, fills absorbable material oval near the lower wall side of human body upper end hole and the upper wall side of following stomidium, will lead nail with pinning again and fix with the bone wall.After the absorbable material in the oval-shaped locking nail hole A is absorbed gradually, pinning has downwards and the space that moves up in main nail hole, main nail promptly can move up and down with respect to pinning, moving of main nail produces pressure to tibia, help the dynamic property in fracture site later stage to fix, accelerate its growth healing.
Be threaded on the hole wall of locking nail hole C of the present utility model, help having the passing through of pinning of cancellous threads.
In sum, this utility model is a kind of multi-functional tibia intramedullary nail with lock.It can insert more easily and be fixed in the tibia pulp cavity, improves the dissection adaptability of tibial intramedullary nailing, avoids swinging the bone does not connect that causes because of the side in pulp cavity, can treat fracture and ankle fracture under the tibial plateau.
