Abstract
The utility model relates to a medical intramedullary nail, in particular to an intramedullary nail for treating long bone fracture postoperative infection. The intramedullary nail comprises an intramedullary nail main body; and a proximal end connector and a far-end connector are arranged on the intramedullary nail main body, and are connected with a drainage connecting pipe and a vacuum suction connecting pipe respectively. Compared with the prior art, in case of infection, the drainage connecting pipe and the outside are connected to form a water inflow end, and the vacuum suction connecting pipe and a vacuum extractor are connected to form a water outflow end, so that a smooth lavage and drainage system which can directly act on a focus is formed, for curing infection and providing favorable conditions for bone healing simultaneously.
Description
Technical field:
This utility model relates to a kind of medical intramedullary needle, a kind of specifically intramedullary needle of treating the long bone fracture postoperative infection.
Background technology:
Intramedullary needle can provide the stable centers type to fix, and in the treatment long bone fracture, is widely used.Infect but maximum drawback is exactly, consequence is serious, infects the whole pulp cavity of diffusion.If do not remove intramedullary needle, infection is difficult to control; If the removal intramedullary needle, the internal fixation operation utter failure, the function of joint forfeiture, patient can not accept.Infect in the marrow, the position is dark, fully drain, and wound opens wide and changes dressings, and less patient suffering is difficult to cooperate.Following lavage and drainage pipe, stifled easily, effect is uncertain, and is very thorny.
The utility model content:
The goal of the invention of this utility model is to overcome the deficiency of background technology and a kind of intramedullary needle of treating the long bone fracture postoperative infection is provided.
This utility model adopts following technical scheme:
A kind of intramedullary needle of treating the long bone fracture postoperative infection comprises the intramedullary needle body, is respectively equipped with local interface and remote interface on the said intramedullary needle body, and this local interface is connected with the vacuum suction connection tube with the drain connection tube respectively with remote interface.
This utility model of employing technique scheme compared with prior art; When occurring infecting; The drain connection tube constitutes water inlet end with extraneous the connection, and the vacuum suction connection tube formation water side that links to each other with vacuum extractor can form the lavage and drainage system of a unobstructed and through focus; When infecting for curing is that union of fracture provides advantage.
As a kind of preferred version of this utility model, said local interface places the intramedullary needle body to be provided with an end of kink.
As a kind of preferred version of this utility model, the perpendicular setting of axis of the axis of said vacuum suction connecting leg and intramedullary needle body bottom.
Description of drawings:
Fig. 1 is the structural representation of utility model.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment this utility model is detailed:
A kind of intramedullary needle of treating the long bone fracture postoperative infection is referring to accompanying drawing 1, among the figure: intramedullary needle body 1, local interface 2, drain connection tube 3, pinning 4, vacuum suction connection tube 5, remote interface 6, kink 7.
In the present embodiment, the two ends of intramedullary needle body 1 are respectively equipped with local interface 2 and remote interface 6, and local interface 2 is connected with vacuum suction connection tube 5 with drain connection tube 3 respectively with remote interface 6.Drain connection tube 3 is steel design with vacuum suction connection tube 5.
As a kind of preferred structure of present embodiment, local interface 2 places intramedullary needle body 1 to be provided with an end of kink 7, and remote interface 6 can join with the other end interface of intramedullary needle body 1.
As a kind of preferred structure of present embodiment, the perpendicular setting of axis of the axis of vacuum suction connecting leg 5 and intramedullary needle body 1 its underpart.
Postoperative is connected drain connection tube 3 as infecting with outside water inlet, negative pressure drainage connection tube 5 links to each other with vacuum extractor, is outlet; Form the lavage and drainage system of a unobstructed and through focus.Because drain connection tube 3 all is steel tube structures with vacuum suction connection tube 5, can topical in the lavage and drainage process, adding negative pressure can be not flat yet; If can be used the mediation of steel wire guide pin by clogged with tissue; Like the muscle gap focus of infection is arranged, then add partial drain again.If infection symptoms disappears, then remove drain connection tube 3 and vacuum suction connection tube 5, observed for three weeks, like infection and recurrence, connection interface continues drain again, can be until union of fracture.As long as drain is abundant, transference cure has to infect and cures and the also possibility of healing of fracturing.
Claims (3)
1. intramedullary needle of treating the long bone fracture postoperative infection; Comprise the intramedullary needle body; It is characterized in that: be respectively equipped with local interface and remote interface on the said intramedullary needle body, this local interface is connected with the vacuum suction connection tube with the drain connection tube respectively with remote interface.
2. a kind of intramedullary needle of treating the long bone fracture postoperative infection according to claim 1 is characterized in that: said local interface places the intramedullary needle body to be provided with an end of kink.
