Description
Technical field
The utility model is related to a kind of micro wound coaptation plate for treating acropathy long bone fractures, belongs to orthopedic medical device technology neck
Domain.
Background technology
In orthopaedics therapy, acropathy long bone fractures are clinically common disease and frequently-occurring disease, mainly due to external force collision, fall
Fall, caused by the natural calamity such as traffic accident accident and earthquake.For shaft fracture, ripe technology is treated using marrow nail,
But when some are also the fine indication of Interal fixation, such as near-end or less distal bone folded block, application Interal fixation is undoubtedly more
Excellent selection.During application Interal fixation, clinician need to consider two kinds of situations：If fixation is excessively stable, poroma can be affected to be formed,
Speed of fracture union is affected then；Stress raisers can be caused if fixed shakiness, it is likely that the fatigue fracture of steel plate occur
Situation.But most notably, as steel plate is directly contacted with bone face, and pressurize so that periosteal vessels net is oppressed,
The blood supply of cortex of bone is affected, the cortex of bone necrosis for local occur finally slows down the healing rate of fracture, or even fracture occurs
Delayed union or the phenomenon of disunion.With the extensive development of orthopaedics Minimally Invasive Surgery, the superiority of Minimally Invasive Surgery day by day manifests,
Apply Minimally Invasive Surgery also imperative in treatment acropathy long bone fractures, but the bone plate width for using at present is big, is not suitable with minimally invasive
Operation, more importantly as the weak point of above-mentioned Interal fixation does not obtain effectively solving so far so that Interal fixation
Apply and there is very big uncertainty in Minimally Invasive Surgery, it would be highly desirable to which medical worker and scientific research personnel solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of elastic micro wound coaptation plate for long bone fracture, this
Kind of bone plate has certain elasticity, stress that can effectively suffered by dispersion bone plate, prevents bone plate stress concentration from breaking
Split, the compressing to local cortex of bone rete vasculosum can also be reduced, so as to greatly reduce local cortex of bone because blood supply is not enough
The necrosis of appearance, promotes union, is particularly well-suited to Minimally Invasive Surgery application.
Solve above-mentioned technical problem technical scheme be：
A kind of elastic micro wound coaptation plate for long bone fracture, it is elongated plates, and the plate face of bone plate is along length side
To undulate, the plate face both sides of bone plate have crest and trough to be spaced respectively, have multiple lockings in the plate face of bone plate
Hole, lock hole are uniform in plate face along the length direction of bone plate, and the plate face of bone plate is bent up for centre in the direction of the width
Bent arc, the radian of winding arc are matched with the surface radian in long bone section, the length phase of the length of bone plate and long bone
Adaptation, the width of bone plate is 10-20mm.
The above-mentioned elastic micro wound coaptation plate for long bone fracture, the corrugated crest of the bone plate length direction and trough
Respectively 10-30, the highly identical and shape of crest and trough is mutually matched.
The above-mentioned elastic micro wound coaptation plate for long bone fracture, the lock hole of the bone plate are located at the center line of bone plate
On, or the both sides of the edge positioned at bone plate, or protrude in the outside of bone plate, within the 20-50mm of fracture line both sides
Fracture line region latch-up-free hole.
The above-mentioned elastic micro wound coaptation plate for long bone fracture, the position of the lock hole of the bone plate and bone plate wave
The crest of shape is relative, or relative with corrugated trough, or is located between corrugated crest and trough.
The above-mentioned elastic micro wound coaptation plate for long bone fracture, the top of the lock hole is circular groove, and bottom is spiral shell
Hole, the depth of circular groove and diameter are matched with the height and diameter of the head of a nail of lock screw, the diameter of screw with locking spiral shell
The external diameter of nail matches.
The beneficial effects of the utility model are：
The utility model adopts wavy shape, with following remarkable advantage：
First, bone plate is undulated design, stress that can effectively suffered by dispersion bone plate, prevents bone plate stress
Concentrate, the fracture of bone plate occur then；Secondly, the general fixation steel plate of the width ratio of bone plate is narrow a lot, about commonly uses
2nd/to three/6ths of fixation steel plate, it is possible to reduce the compressing to local cortex of bone rete vasculosum, so that greatly reduce office
The necrosis that portion's cortex of bone occurs because blood supply is not enough；It is equally important that due to adopting undulated design, bone plate is vertical
By the weight of human body, the certain elasticity of Xiang Keyou, based on this, if being applied to lower limb, can realize that fracture end pressurizes, stimulate fracture
The revascularization at end, so that promote union.
The utility model is the pioneering of long bone fracture bone plate, solve bone plate present in existing Interal fixation in response to
Power concentrate rupture, oppress periosteal vessels net cause impact cortex of bone blood supply and occur local cortex of bone downright bad,
The difficult problem for affecting healing of fracture etc. not solve for a long time, provides effectively for Interal fixation used in long bone fracture Minimally Invasive Surgery
Science and technology support, with significant economic and social benefit.
