Abstract
The utility model discloses a fracture pressure intramedullary fixed nail with a lock, which consists of a intramedullary fixed nail and a lock pin. A tread is arranged near the tip point of the intramedullary fixed nail and a groove is arranged on the tail part of the nail. An inclined hole is arranged on the groove part. The lock nail is locked with the intramedullary nail through the inclined hole. The utility model has the advantages of reasonable design, simple structure and low cost. A rotating entering way is adopted to press and extrude a fracture part. And a near end is adopted to use the lock nail to lock the intramedullary nail in a way of oblique. The lock nail is effectively prevented from rotating and withdrawing. Therefore, the operation is simple and convenient. The whole operation process is convenient and rapid (only 20 minutes needed). The fracture part can be pressured, extruded on opposite laterals and fixed without an incision (closed perforating).
Description
(1) technical field:
This utility model belongs to medical instruments field, and what relate generally to is a kind of fracture with compressive marrow internal fixation nail with lock.
(2) background technology:
At present, clinical Therapeutic Method to the fracture internal fixation has a lot, and the internal fixation device that can Gong select for use is also varied.The marrow internal fixation nail does not destroy characteristics such as outer periosteum, fixedly great efforts, union of fracture be fast with it and gets a good review.But owing to it costs an arm and a leg, trivial operations, thereby application still has certain limitation clinically.The marrow nail of producing as Jiangsu Wujin Medical Apparatus and Instruments Factory with lock just has four pinnings, in use need be through enlarging steps such as pulp cavity, fracture para-position, sight location, far and near end pinning, the general requirement carried out under operation, whole process needs more than two hours, not only strengthen medical workers, and increased the weight of patient's misery.
(3) summary of the invention:
In view of the foregoing, the purpose of this utility model promptly produces thus, propose a kind of fracture with compressive marrow internal fixation nail with lock, use this staple not only can reduce cost of use, simplify the operation course, and need not operative incision and both can realize that pressurization is fixing to squeezing fracture site.
For achieving the above object, this utility model is achieved through the following technical solutions: it is made up of intramedullary pin and pinning, the position, tip is provided with screw thread, the nail tail bit is provided with groove near following closely at intramedullary pin, and is provided with an inclined hole at this groove position, and pinning and intramedullary pin are by this inclined hole socket locking.
This utility model is reasonable in design, and is simple in structure, cheap.Because it adopts the mode that rotates into that fracture site is formed pressurization to squeezing, adopt near-end to be oblique again to the intramedullary pin locking with pinning, effectively prevented the rotation of pinning and withdrawed from.Thereby simple to operation, whole operation process convenient and swift (only needing 20 minutes) need not operative incision (closure penetrates) and can realize the pressurization of fracture site fixing to squeezing.
(4) description of drawings:
This utility model accompanying drawing is a structural representation.
Among the figure, 1-intramedullary pin, 2-pinning, 3-screw thread, 4-groove.
(5) specific embodiment:
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure, present embodiment is made up of intramedullary pin 1 and pinning 2, is provided with near nail position, tip at intramedullary pin 1 to be used to rotate propulsive screw thread 3, and the nail tail bit is hemispherical, which is provided with the groove 4 of available screwdriver rotation intramedullary pin, be provided with an inclined hole at this groove position.What pinning 2 adopted is common medical nail or cancellous bone screw, and itself and intramedullary pin 1 are by being located at the inclined hole socket locking on the intramedullary pin nail tail groove position.When present embodiment uses clinically, with (humeral fracture is an example): shoulder routine disinfection drape, in greater tubercles of humerus the place ahead is that a 0.5cm otch is made in the intertubercular sulcus outside, make a call to a bone hole with bradawl in the greater tubercle front portion, existing intramedullary pin thickness is suitable, the nail point of intramedullary pin is entered in the hole thus, nail tail to the intramedullary pin of intramedullary pin of pounding with a hammer is squeezed into nearly fracture end, with the reduction of the fracture, continuation was squeezed into fracture end far away at about 3/4ths o'clock with intramedullary pin, advance with screwdriver turn-knob nail tail, tail is consistent with the greater tubercles of humerus plane until following closely, and pinning is socketed in the inclined hole with screwdriver the pinning screw-in is got final product.
Claims (2)
1, a kind of fracture with compressive marrow internal fixation nail with lock, comprise intramedullary pin (1), pinning (2), it is characterized in that: be provided with screw thread (3) near nail position, tip at described intramedullary pin (1), the nail tail bit is provided with groove (4), be provided with an inclined hole at this groove (4) position, described pinning (2) is by this inclined hole and intramedullary pin (1) socket locking.
2, fracture with compressive according to claim 1 marrow internal fixation nail with lock, it is characterized in that: described inclined hole and intramedullary pin (1) are 30 ° of oblique angles.
