Technical Field
The utility model relates to an orthopedics medical instrument field, concretely relates to tibiofibular fusion fixed plate down.
Background
Tibiofibular fracture is most common in long tubular fracture, and tibiofibular dry fracture has a tibia shallow under the skin and lacks of a muscle cover, so that the fractured end of the tibiofibula is easy to break the skin after fracture. Tibiofibular fracture, which is common in children and young and old, is usually caused by direct violence, and if it occurs in the middle and lower segments, delayed healing or nonhealing is likely to occur. Since the bleeding of marrow cavity and blood vessel or muscle injury after fracture can cause the pressure of periosteum chamber to increase, the tibia and fibula should be fixed by operation in time after fracture. The patient of shin bone and fibula fracture simultaneously takes place among the tibiofibula fracture patient, and current internal fixation mode does, uses two steel sheets and cooperation screw respectively to be fixed in on shin bone and the fibula respectively, then uses a long screw again with connection shin bone and fibula, prevents that shin bone and fibula from taking place the separation. However, the above-described fixing method has the following problems: 1. because the tibia and the fibula are fixed separately, the problem of stress concentration is easy to occur when the long screw is stressed unevenly, and the long screw is broken; 2. the existing screw and the steel plate are mostly connected in a single matching mode of extrusion and thread, once the screw falls off from a tunnel of a fibula or a tibia, the screw is easy to fall off from the steel plate due to lack of necessary restraint and extrudes skin to cause the problem of local uplift and even skin puncture.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model designs a tibiofibular fusion fixing plate, the fixation between the steel plate and the screw is more compact, and the jackscrew is added between the steel plate and the screw, which can prevent the screw from dropping out of the steel plate after loosening to cause the problems of skin uplift and puncture; this steel sheet can be fixed tibia and fibula simultaneously, has cancelled the use of long screw, prevents the problem that the fracture of long screw leads to tibia and fibula separation to appear.
In order to achieve the purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a tibiofibula fuses fixed plate, includes and unites steel sheet, jackscrew and set screw, and set screw is detachable to be fixed in on uniting the steel sheet, and the jackscrew just forms the extrusion to set screw with uniting steel sheet threaded connection. The combined steel plate is of an integrated structure formed by a tibia fixing plate and a fibula fixing plate, the fibula fixing plate is a bent plate, a row of locking holes are formed in the tibia fixing plate and the fibula fixing plate respectively, the number of each row of locking holes is not less than 2, each locking hole is a through hole and consists of a top thread hole and a screw counter bore, each screw counter bore comprises a screw cap hole and a screw rod hole, the top thread holes and the screw cap holes are threaded holes, and the screw rod holes are smooth holes; the side wall of the jackscrew is provided with a connecting thread, the top of the jackscrew is provided with a quincunx socket, and the jackscrew is in threaded connection with the jackscrew hole; the fixing screw comprises a screw cap and a screw body, connecting threads are arranged on the side wall of the screw cap, a quincunx socket is formed in the top of the screw cap, the connecting portion of the screw body and the screw cap is a smooth portion, meshing threads are arranged on the screw body below the smooth portion, and the screw cap of the screw body is in threaded connection with a screw cap hole of a screw counter bore.
Furthermore, the width of the tibia fixing plate is 2cm, and the arc length of the fibula fixing plate is 1 cm.
Further, the number of the locking holes is 3.
The utility model has the advantages that: the steel plate and the screw are fixed more tightly, and a jackscrew is added between the steel plate and the screw, so that the problems of skin uplift and puncture caused by the fact that the screw is separated from the steel plate after loosening can be prevented; this steel sheet can be fixed tibia and fibula simultaneously, has cancelled the use of long screw, prevents the problem that the fracture of long screw leads to tibia and fibula separation to appear.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 5, a tibiofibula fusion fixation plate includes a joint steel plate 1, a jackscrew 2 and a fixation screw 3, the fixation screw 3 is detachably fixed on the joint steel plate 1, the jackscrew 2 is connected with the joint steel plate 1 by screw thread and extrudes the fixation screw 3. The combined steel plate 1 is of an integrated structure consisting of a tibia fixing plate 11 and a fibula fixing plate 12, the width of the tibia fixing plate is 2cm, and the arc length of the fibula fixing plate is 1 cm. The fibula fixing plate 12 is a bent plate, a row of locking holes are formed in the tibia fixing plate 11 and the fibula fixing plate 12 respectively, the number of each row of locking holes is 3, each locking hole is a through hole and consists of a top thread hole 13 and a screw counter bore, each screw counter bore comprises a screw cap hole 14 and a screw rod hole 15, the top thread hole 13 and the screw cap hole 14 are threaded holes, and each screw rod hole is a smooth hole; the side wall of the jackscrew 2 is provided with connecting threads, the top of the jackscrew 2 is provided with a quincunx socket, and the jackscrew 2 is in threaded connection with a jackscrew hole 13; the fixing screw 3 comprises a screw cap 31 and a screw body 32, connecting threads are arranged on the side wall of the screw cap 31, a quincunx socket 4 is formed in the top of the screw cap 31, the connecting portion of the screw body 32 and the screw cap 31 is a smooth portion, meshing threads are arranged on the screw body below the smooth portion, and the screw cap 31 of the fixing screw 3 is in threaded connection with a screw cap hole 14 of a screw counter bore.
One specific application of the device is as follows: firstly, a threaded tunnel is drilled on the tibia and the fibula of a patient by using a bone drill, the tibia fixing plate 11 and the fibula fixing plate 12 of a combined steel plate are respectively attached to the tibia and the fibula of the patient, then the fixing screw 3 is inserted into the threaded tunnel of the tibia and the fibula through a locking hole of the combined steel plate and screwed in, and finally the top thread 2 is screwed in the top thread hole 13 so that the top thread 2 extrudes the fixing screw 2. Because the fixing screw 2 is under the limiting action of the jackscrew, the fixing thread 2 can not be separated from the combined steel plate 1 even if loosening occurs in the thread tunnel of the tibia or the fibula, and the problems of local skin swelling and puncture caused by falling of the screw are prevented. Because the steel plate integrates the tibia fixing plate 11 and the fibula fixing plate 12, the fixing steps of the steel plate can be reduced, implantation of long screws can be omitted, and the problem of tibia and fibula separation caused by fracture of the long screws is solved.
