Abstract
A kind of Patella fracture strap, belong to medical sanitary technology, relating to field of orthopaedics, is exactly the technique for fixing about Patella fracture.A kind of Patella fracture strap, comprises connected nail, is characterized in: connected nail is screw, and screw, through the screw held on the ring-type shaping steel plate strip of fracture patella, fasteningly screws up on the patella of the fracture of fitting by fracture line; Described patella, has femur, tibia, fibula around; Described ring-type shaping steel plate strip, tangible as patella flexibility, its thickness is concavo-convex to distribute alternately, and bossing has the hole of wearing screw.The good effect implemented after this utility model is: this utility model has good mechanical stability, favourable patients with functional exercise; Loop configuration globality is strong, and be suitable for patella polylith fracture fixation, the scope of application is large; Concavo-convex alternate design reduces the impact for the confession of patella surface blood, and growth promoting effects heals, and also reduces patient's foreign body sensation; Use easy to operate.
Description
Technical field
Belong to medical sanitary technology, relating to field of orthopaedics, is exactly the technique for fixing about Patella fracture.
Background technology
What existing fixing Patella fracture was conventional has with under type: cerclage fixation: with 18 ~ No. 28 stainless steel silks, guide with thick round needle, is close to patella edge soft tissue inseam unification circle around, then by the kneecap reduction of the fracture, steel wire is tightened up gradually, twists jail.This Measures compare is simple, fixing also more perfect, but easily produces angulation deformity, and be generally applicable to be shifted not too large fracture or the comminuted fracture that still can reset; Run through fixation: with 2mm drill bit outside in 1cm on proximal fracture block section, perpendicular to the patella longitudinal axis, bore a tunnel; With same method, also bore a tunnel at the corresponding site of distal fracture block, 8 shapes are through steel wire.But notably tunnel should be positioned at the rear of the complete thick mid point of patella.With towel forceps reset, tighten fixation with steel wire it.This fixing directly, effectively, more firm, be applicable to the larger fracture that is shifted.Because steel wire intersects at facies anterior patellae, the angled forward caused when going down on one's knees can be prevented.Tension band fixation method: with the Kirschner wire of diameter 1.5mm, pierces from the medial and lateral in nearly folded block folding face, along the patella longitudinal axis, gets out from the top of sclerite, just exposed folding face with bitbrace adjustment Kirschner wire to syringe needle.After reset, pierce by the corresponding point in same Kirschner wire folding face from nearly folded block to folded block far away, get out along the lower end of the patella longitudinal axis from folded block far away.Adjust Kirschner wire with bitbrace, make two ends outside sarolemma, expose about 3 ~ 5mm, backshank hook, then walk around after two pieces of Kirschner wires with 18 ~ No. 28 steel wires, tighten up gradually and twist jail.When tightening, notice that steel wire should pass the rear side of Kirschner wire and tighten up.Like this, after steel wire tightens up, Kirschner wire will be subject to certain pressure, impel sclerite to draw close mutually, healing acceleration; Should also be noted that the steel wire that never stringer can be made to stride across fracture line is too partial to side, thus lose the effect of tension band fixation.
There is complex operation in these methods, technical requirement is high, and each inside-fixture lacks globality, the shortcoming that firmness is general.
Summary of the invention
This utility model provides a kind of handled easily, good integrity, a kind of Patella fracture strap of fix tightly.
The technical scheme that this utility model is taked:
A kind of Patella fracture strap, comprise connected nail, its scheme is: connected nail is screw, and screw, through the screw held on the ring-type shaping steel plate strip of fracture patella, fasteningly screws up on the patella of the fracture of fitting by fracture line; Described patella, has femur, tibia, fibula around; Described ring-type shaping steel plate strip, tangible as patella flexibility, its thickness is concavo-convex to distribute alternately, and bossing has the hole of wearing screw.
The good effect implemented after this utility model is:
Implement the good effect after this utility model:
This utility model has good mechanical stability, favourable patients with functional exercise; Loop configuration globality is strong, and be suitable for patella polylith fracture fixation, the scope of application is large; Concavo-convex alternate design reduces the impact for the confession of patella surface blood, and growth promoting effects heals, and also reduces patient's foreign body sensation; Use easy to operate.

Fig. 2, be this utility model diagrammatic side-view cross-sectional structural representation,
Fig. 3, be this utility model using state schematic diagram.
Detailed description of the invention
Now the utility model is described in further detail by reference to the accompanying drawings
A kind of Patella fracture strap, comprises connected nail, it is characterized in that: connected nail is screw, and screw, through the screw held on the ring-type shaping steel plate strip of fracture patella, fasteningly screws up on the patella 5 of the fracture of fitting by fracture line 6; Described patella, has femur 10, tibia 11, fibula 12 around; Described ring-type shaping steel plate strip 3, tangible as patella flexibility, its thickness is concavo-convex to distribute alternately, and bossing 4 has the hole 2 of wearing screw 1.
Described thickness is concavo-convex to distribute alternately, and its female thickness gets 1mm; Bossing thickness gets 2mm.
Described ring-type shaping steel plate strip 3 selects light titanium alloy.
