Abstract
The utility model relates to a distal humerus nickel titanium memory alloy coaptation device, which comprises a coaptation plate. The coaptation device is characterized in that the coaptation plate is a long frame whose transverse short frame edge shapes like an arc; the two lateral long frame edges on the back are provided with an aliform encircle plate; an inverse E shape wing is arranged on the upside of the long frame; the inverse E shape wings on the two sides are staggered mutually; an axial pressure support which shapes like an arc and warps upward is arranged on the front part, which is parallel with the long frame edge; a pressure hook is arranged on the top of the pressure support; the periphery of the pressure hook is provided with zigzag salient; a distal fixing rod which has an 45 degrees angles with the long frame plane and extends upward is arranged on the two front vertex angles of the long frame; the angle between the projection line of the distal fixing rod and the extension lines of the two lateral long frame edges are 45 degrees; the angel between the apical inflexed hook of the distal fixing rod and the distal fixing rod is 80 degrees; two lateral fixing supports are arranged on the outer lateral edges of the distal fixing rods. The utility model has the advantages that the anatomic form of the humeral supracondylar is effectively maintained; the fracture end is continuously and uniformly pressed; the cooperation between the fracture end axial pressure and the maintaining of the anatomic form is realized; the utility model is provided with shearing resistance, rotating resistance, and departing resistance.
Description
Technical field
This utility model relates to a kind of fracture internal fixation bone fracture device, particularly a kind of distal humerus Ultimum Ti bone fracture device.
Background technology
Supracondylar fracture of the humerus is the extra-articular fracture of the nearly joint capsule of Hong bone far-end, is mainly in the child in 2-15 year, and after fracturing, because the effect of biceps brachii m. and triceps brachii forms the shearing consistent with fracture line in fracture end, fracture end has cripetura to be inclined to; Because musculus flexor strength is stronger, the front side produces pressure on condyle, produces tension force at dorsal part, the fracture end tendency that leans forward; The tractive of the cracked and forearm muscle group of interior outside supporting pillar and the action of gravity of itself, making supracondylar fracture of the humerus all have ulnar side to incline revolves, the tendency that departs from, supracondylar fracture of the humerus commonly used resets and fixing employing skin traction, but the probability that the cubitus varus takes place is arranged, and need repeatedly bedside to take the photograph sheet, because of the skin tension blister stops traction.Existing also have chevron shaped steel plate internal fixation, though the high elastic modulus steel plate prevented the ulnar side of fracture far-end incline revolve, cripetura, stress force shelter reaction is arranged, and the periosteum large tracts of land is peeled off and will be influenced skeletal growth, unfavorable factors such as operation complexity.
Summary of the invention
The purpose of this utility model is that because the effect of biceps brachii m. and triceps brachii forms the shearing consistent with fracture line in fracture end, fracture end had the cripetura tendency after condyle of humerus was fractured in the solution prior art; Because musculus flexor strength is stronger, the front side produces pressure on condyle, produces tension force at dorsal part, the fracture end tendency that leans forward; The tractive of the cracked and forearm muscle group of interior outside supporting pillar and the action of gravity of itself, making supracondylar fracture of the humerus all have ulnar side to incline revolves, the tendency that departs from, supracondylar fracture of the humerus commonly used resets and fixing employing skin traction, but the probability that the cubitus varus takes place is arranged, and need repeatedly bedside to take the photograph sheet, because of the skin tension blister stops traction.Existing also have chevron shaped steel plate internal fixation, though the high elastic modulus steel plate prevented the ulnar side of fracture far-end incline revolve, cripetura, stress force shelter reaction is arranged, and the periosteum large tracts of land is peeled off and will be influenced skeletal growth, the operation complicated problems.This utility model design distal humerus Ultimum Ti bone fracture device, comprise blade plate, it is characterized in that: blade plate is a long frame shape, its laterally short edge is circular arc, both sides, rear portion long frame edge has wing to encircle plate, wing is encircled plate top a mountain font wing, the mountain font wing that the wing on both sides is encircled on the plate is interlaced, the axial pressure that forward horizontal short edge inboard has an arc to upwarp is propped up, the projection line that axial pressure is propped up is parallel with long frame edge, the top that pressurization is propped up is for adding pressure hook, the periphery that adds pressure hook has the zigzag projection, on anterior two drift angles of long frame shape, have with the long frame shape plane and be the far-end fixed bar that 45 degree angles are stretched to the upper edge, the extension line of the projection line of far-end fixed bar and both sides long frame edge is 45 degree angles, the top invagination hook of far-end fixed bar and far-end fixed bar are 80 degree angles, and fixing of two sides are arranged on the far-end fixed bar outer side edges.The utility model has the advantages that and can effectively keep anatomic form on the condyle of humerus, continue evenly to stress on fracture end, it is collaborative to realize that fracture end axial pressure and anatomic form are kept, shearing resistance is anti-revolve resist from.
Description of drawings
Below in conjunction with drawings and Examples this utility model is elaborated,
Accompanying drawing 1 is a structural upright sketch map of the present utility model,
Accompanying drawing 2 is a structure vertical view of the present utility model,
Accompanying drawing 3 is user mode figure of the present utility model,
Comprise blade plate 1 among the figure, it is characterized in that: blade plate 1 is a long frame shape, its laterally short edge 2 is circular arc, both sides, rear portion long frame edge 3 has wing to encircle plate 4, wing is encircled plate 4 tops a mountain font wing 5, the mountain font wing 5 that the wing on both sides is encircled on the plate 4 is interlaced, the axial pressure that inboard, forward horizontal short frame 2 limit has an arc to upwarp props up 6, it is parallel with long frame edge 3 that axial pressure is propped up 6 projection line, pressurization is propped up 6 top for adding pressure hook 7, the periphery that adds pressure hook 7 has zigzag projection 8, on anterior two drift angles of long frame shape, have with the long frame shape plane and be the far-end fixed bar 9 that 45 degree angles are stretched to the upper edge, the extension line of the projection line of far-end fixed bar 9 and both sides long frame edge 3 is 45 degree angles, the top invagination hook 10 and the far-end fixed bar 9 of far-end fixed bar 9 is 80 degree angles, and fixing 11 of two side arranged on far-end fixed bar 9 outer side edges.During use with distal humerus Ultimum Ti bone fracture device low temperature flow, then that the long frame edge 3 of blade plate 1 is consistent with the key longitudinal axis, launching wing encircles plate 4 and makes it staggeredly clasp the backbone, fixing 11 supporting pillar of clasping both sides in far-end fixed bar 9 and two side, in interior outside supporting pillar end, more than the bone growth district, vertical facial is holed, and inserts the top invagination hook 10 of far-end fixed bar 9, and it is docile and obedient to thump, prop up 6 length according to axial pressure, on the backbone, bore saturating two-layer cortical bone, then axial pressure is propped up 6 top and add pressure hook 7 and insert in the bone hole knocking, the warm saline rewarming, distal humerus Ultimum Ti bone fracture device is replied to shape memory, forms the sustained stress of prolonging the key longitudinal axis, is passed to fracture end, promote the healing of fracture, kept the anatomic form of distal humerus.
