Abstract
The invention relates to a multiaxial universal nail which belongs to the technical field of medical appliances. The multiaxial universal nail comprises a universal fixator, a universal bulb nail, a universal nail ring and a rivet, wherein the universal bulb nail is connected with the universal fixator through the rivet, the universal fixator is positioned above the universal bulb nail, and the universal nail ring is positioned in the universal fixator and comes into contact with the universal bulb nail. The multiaxial universal nail has the advantages of high strength, strong binding force with bones, novel and reasonable structure design, simplicity and convenience in operation, easiness in grasping of the installation technology, less auxiliary accessories and good stability and fatigue resistance, all kinds of complications caused by insufficient strength of implantation materials are greatly reduced after the operations, and favorable guarantee is provided for recovery of patients.
Description
Technical field
The present invention relates to a kind of multiaxis universal nail, belong to technical field of medical instruments.
Background technology
Current, the operation method of surgery is in constantly development, various internal fixation devices have also appearred thereupon, as long as comprise various bone screw, hamulus of hamate bone, round metal bars and metallic plate etc., but it does not have the multiaxis universal nail to be widely used, but present common several universal bone screw all has pluses and minuses separately, with regard to shortcoming since the screw rod solid section of various Universal screw nails be about consistent cylindrical of diameter, cause the screw cervical region thinner, lack enough intensity, also inadequate with the adhesion of sclerotin; In addition, existing Universal screw nail installs also complicated, and operation easier is large, so be subject to certain restrictions in clinical use, also is unfavorable for the operative treatment of numerous disease.
Summary of the invention
For solving above-mentioned technical problem of the prior art, the invention provides a kind of multiaxis universal nail, this multiaxis universal nail intensity is high, and is strong with the adhesion of sclerotin, simple, practical for patients ' recovery provides favourable guarantee, and with low cost.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of multiaxis universal nail, comprise universal holder, universal ball end nail, the universal nail collar and rivet, described universal ball end nail is connected by rivet with universal holder, and universal holder is positioned at the universal ball end side of nailing on, the universal nail collar is positioned at universal holder, and touches with the universal ball end nail joint.
Described universal ball end nail is provided with sharp portion.
Described universal ball end nail is solid universal ball end nail.
Described universal holder is the universal holder of long-tail.
Described universal ball end nail is long-tail universal ball end nail.
Described universal holder is the universal holder of chromium, the universal holder of nickel, the universal holder of molybdenum, the universal holder of titanium or the universal holder of aluminum.
Described universal ball end nail is chromium universal ball end nail, nickel universal ball end nail, molybdenum universal ball end nail, titanium universal ball end nail or aluminum universal ball end nail.
The described universal nail collar is the chromium universal nail collar, the nickel universal nail collar, the molybdenum universal nail collar, the titanium universal nail collar or the aluminum universal nail collar.
Described rivet is chromium rivet, nickel rivet, molybdenum rivet, titanium rivet or aluminium rivet.
Beneficial effect of the present invention is as follows:
Multiaxis universal nail of the present invention, intensity is high, strong with the adhesion of sclerotin, structural design is new reasonable and operation technique is easy, mounting technique is grasped easily, auxiliary accessories is few, have good stability and fatigue resistance, greatly reduce the various complication that cause owing to the implant undercapacity after performing the operation, for patients ' recovery provides favourable guarantee.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention;
Wherein, 1 is that universal holder, 2 is sharp portion for rivet, 5 for the universal nail collar, 4 for universal ball end nail, 3.
The specific embodiment
The invention will be further described below in conjunction with the specific embodiment, but protection scope of the present invention is not limited to this.
Embodiment
As shown in Figure 1, multiaxis universal nail of the present invention, comprise universal holder 1, universal ball end nail 2, the universal nail collar 3 and rivet 4, universal ball end nail 2 is connected by rivet 4 with universal holder 1, universal holder 1 is positioned at universal ball end and follows closely 2 tops, the universal nail collar 3 is positioned at universal holder 1, and contacts with universal ball end nail 2.Universal ball end nail 2 is solid long-tail universal ball end nail 2, and is provided with sharp portion 5; Universal ball end nail 2 is long-tail universal ball end nail.
Multiaxis universal nail of the present invention, intensity is high, strong with the adhesion of sclerotin, structural design is new reasonable and operation technique is easy, mounting technique is grasped easily, auxiliary accessories is few, have good stability and fatigue resistance, greatly reduce the various complication that cause owing to the implant undercapacity after performing the operation, for patients ' recovery provides favourable guarantee.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
