Abstract
The invention discloses an outer fixing device for minimally invasive surgery. The outer fixing device for minimally invasive surgery is characterized by comprising a fixed frame body. Two sides of the fixed frame body are respectively provided with multiple outer fixing nails. The fixed frame body and the outer fixing nails are made of titanium alloy. As an improvement, the fixed frame body comprises multiple fixed rods which are parallel to each other. Adjacent fixed rods are connected into wholes through multiple sway bracing devices. The outer fixing nails are movably connected on the fixed rods. The titanium alloy fixed rods, the titanium alloy sway bracing devices and the titanium alloy outer fixing nails are used by the outer fixing device for minimally invasive surgery. The sway bracing devices and the outer fixing nails are movably connected on the fixed rods through nuts. The outer fixing device for minimally invasive surgery is good in performance, sufficient in sliding poking effect, capable of effectively maintaining outward expansion position of an end near to a hip fracture, diverse and flexible in adjustment manner, fastened in fixation and suitable for complicated fracture conditions.
Description
Technical field
The invention belongs to operation and using the fixed mount field, specifically, relating to a kind of Minimally Invasive Surgery external fixator.
Background technology
The fracture Minimally Invasive Surgery uses microscope or high magnified glass, amplifies surgical field of view and carries out operation technique, implements " keyhole operation " by as far as possible little skin incision, makes the orthopaedics surgical operation implement the most effectively treatment with the iatrogenic injury of minimum.At present, at the therapeutic method of surgery of Hip Fracture, at present mainly take internal fixation treatment as main.For the patient of Therapy of Elder Hip Fracture with osteoporosis, sclerotin is not enough to the hold of bone screw, complication rates such as occurring coxa vara after internal fixation, suffer from the limb cripetura, the cutting of the medial displacement of fracture section far away, lag screw and os integumentale screw are extracted increases greatly, easily causes the failure of internal fixation treatment.For the patients with hip fracture that is difficult to the row internal fixation treatment, use the hip External Fixation in Treatment, certain advantage is arranged.In clinical application, traditional Hip Fracture external fixer shows following deficiency: 1, heavier; 2, lack enough slip sleds and allocate for use, often cause the generation of coxa vara; 3, wound is often larger, and operation technique is complicated.
Summary of the invention
The present invention aims to provide a kind of functional, enough slips sled and allocates for use, can effectively keep the Hip Fracture near-end in outer exhibition position, and the adjustment mode is versatile and flexible, fixed, can adapt to the Minimally Invasive Surgery external fixator of complicated fracture situation.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of Minimally Invasive Surgery external fixator is characterized in that: comprise fixing bracket body, the both sides of fixing bracket body are respectively arranged with several outer staples; Described fixing bracket body and outer staple are all made by titanium alloy material.
As a kind of improvement, described fixing bracket body comprises the some fixed bars that are parallel to each other, and connects as one by some horizontal-associate devices between adjacent fixed bar.
As a kind of improvement, the number of described fixed bar is two, and the number of horizontal-associate device is also two, is flexibly connected between horizontal-associate device and fixed bar.
As a kind of improvement, described horizontal-associate device is socketed on fixed bar, and is provided with nut on the horizontal-associate device.
As a kind of improvement, the both sides of described each root fixed bar are provided with an outer staple.
As a kind of improvement, described outer staple is movably connected on fixed bar.
As a kind of improvement, an end of described outer staple is socketed on fixed bar, and is provided with nut at end position.
As a kind of improvement, described horizontal-associate device is arranged on the fixing bracket body of outer staple inboard.
Owing to having adopted technique scheme, compared with prior art, the present invention is fixed bar, the horizontal-associate device of titanium alloy and the outer staple of titanium alloy with titanium alloy, and horizontal-associate device and outer staple utilize nut to be movably connected on fixed bar.Can adjust as required the position of outer staple and the position of horizontal-associate device during use.The present invention is functional, has enough slip sleds and allocates for use, can effectively keep the Hip Fracture near-end in outer exhibition position, the adjustment mode is versatile and flexible and fixed, can adapt to complicated fracture situation, be applicable to Minimally Invasive Surgery, guarantee the surgical effect of Minimally Invasive Surgery.
The invention will be further described below in conjunction with the drawings and specific embodiments.

The specific embodiment
Embodiment:
As shown in Figure 1 and Figure 2, a kind of Minimally Invasive Surgery external fixator comprises fixing bracket body, and the both sides of fixing bracket body are respectively arranged with several outer staples 1, and described fixing bracket body and outer staple 1 are all made by titanium alloy material.
In the present embodiment, described fixing bracket body comprises the some fixed bars that are parallel to each other 4, connects as one by some horizontal-associate devices 3 between adjacent fixed bar 4.Wherein, the most general form is that the number of fixed bar is two, and the number of horizontal-associate device is also two, be flexibly connected between horizontal-associate device and fixed bar, and the horizontal-associate device is arranged on the fixing bracket body of outer staple inboard.
The horizontal-associate device has various ways, and wherein a kind of is the connecting rod 2 that is socketed on fixed bar, and connecting rod 2 utilizes nut 5 to be movably connected on fixed bar.
In addition, the both sides of each root fixed bar are provided with an outer staple 1 in the present embodiment.Described outer staple 1 is movably connected on fixed bar 4.Wherein best embodiment is that an end of outer staple 1 is socketed on fixed bar 4, and is provided with nut 5 at end position.
The present invention is fixed bar, the horizontal-associate device of titanium alloy and the outer staple of titanium alloy with titanium alloy, and horizontal-associate device and outer staple utilize nut to be movably connected on fixed bar.Can adjust as required the position of outer staple and the position of horizontal-associate device during use.The present invention is functional, has enough slip sleds and allocates for use, can effectively keep the Hip Fracture near-end in outer exhibition position, the adjustment mode is versatile and flexible and fixed, can adapt to complicated fracture situation, be applicable to Minimally Invasive Surgery, guarantee the surgical effect of Minimally Invasive Surgery.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
