Abstract

The invention discloses a spiral bone plate. The spiral bone plate adopts a strip plate body, wherein screw holes are alternately formed in the plate body; the two ends of the plate body are reversely and spirally folded into spiral shapes. The spiral bone plate has the following advantages: the spiral plate body structure can well fit bones, after the bone plate is fixed at the fracture part of a long bone, the axis forms a relatively large angle with the fraction line, the tow ends of the fraction part can be partly wrapped, and the bone plate can compactly fit with a circular bone surface; the elasticity of the bone plate body can be increased, so that the bone plate is enabled to be more similar to human bones in elasticity modulus, the bone plate is more bionic and conforms to the anatomical morphology of human bones and biological force characteristics, the well reset fraction can be firmly fixed, wherein the fixation more conforms to human bone morphology and elasticity modulus, damage to the vessels and nerves around the fraction part can be reduced and even effectively avoided, trauma of soft tissues and bones is reduced, the possibility of postoperative complication is further decreased, and the clinical curative effect is improved; the structure is simple and reasonable, the operation is easy, convenient and flexible, the location is accurate, the fixation is firm, peeled periosteum in the operation is few, the trauma is small, the bone plate conforms to human biomechanics, and the operation efficacy can be effectively improved.

Description

A kind of spiral type blade plate

Technical field

The present invention relates to synthetism fixture, belong to orthopaedic medical treatment technical field.

Background technology

Existing blade plate screw internal fixation is widely used in all kinds of fracture, its blade plate inner surface and bony surface fit tightly, therefore fixing comparatively firm, AO technology just relies on its strong internal fixtion effect and is able to fast development, widely applies at present at clinical particularly basic hospital.But its shortcoming is also apparent: undue pursue Titanic micro-plates and the long incision that causes and soft tissue is separated and periosteum such as extensively to peel off at the problem, causes Treatment of nonunion, infection, canned paragraph osteoporosis and remove a series of severe complications such as fixing rear refracture.Important blood vessels nerve is very easily damaged to some significant points, and the secondary insult caused when internal fixtion takes out is also inevitable.Therefore for above-mentioned situation, from the beginning of the nineties in last century, AO scholar Gerber, Palmar etc. propose the new ideas of fixing (biologicalosteosynthesisBO) biology in succession, emphasize that fractures will pay attention to the biological characteristics of bone, do not destroy the normal physiological context of bone growth and development.Its content mainly comprises: 1. reset away from fracture site, to protect the attachment of fracture local soft tissue; 2. do not impose the anatomical reduction of fracture, intra-articular fracture still requires anatomical reduction; 3. the inside-fixture of low elastic modulus is used; 4. the contact area etc. between inside-fixture and cortical bone is reduced.The blood that core aim is protection bone supplies.But formed one from theory, principle, method to the integral framework of equipment, equipment based on AO technology, the classical advantages such as it is quick, learning cycle is shorter also can not be ignored.Therefore urgently research and develop a kind of can in conjunction with the long bone of limbs height laminating synthetism fixture of AO and BO advantage.

Summary of the invention

The invention provides a kind of spiral type elastic bone plate more can fitted with long bone of limbs, to solve prior art Problems existing.

For realizing the object of the invention, this spiral type elastic bone plate more can fitted with long bone of limbs is a strip plate body, spaced apartly on described plate body plate face is provided with screw, it is characterized in that folding is oppositely revolved respectively in described plate body two ends, revolves the plate body after folding twist.

The technological progress that the present invention obtains:

The present invention is according to skeleton anatomical physiology principle design, be different from existing straight tabular or part deformed steel flats, its spiral-shaped plate body structure reversely rotating design is middle cylindrically, skeleton can be held, for long bone fracture particularly screw type fracture, its spiral line of tension can vertically or near normal fracture line, combine with lock screw, compare general steel plate and obviously can strengthen pressurization to fracture site, this elastic bone plate two end longitudinal axis is antiparallel, 0.1 ~ 2 times of fracture two broken ends of fractured bone can be held, strengthen sclerotin hold, and do not affect the taking-up of its secondary.Spiral type elastic bone plate is because of the particularity of its structure, insert along muscle gap, reduce open reduction to the stripping of muscular fascia, be easy to insert, effectively can avoid important neural blood vessel of fracturing around, as the damage of the radial nerve in radius stage casing, therefore amount of bleeding and the stimulation to surrounding soft tissue can be reduced further.Curved inside spring steel plate, closely can fit with arc surface of bone, its surface uniform distribution 6-12 lock hole, can take the circumstances into consideration to select to fix according to needing in classification of fracture and art.Spiral-shaped plate body structure itself has elasticity, can increase the elastic modelling quantity of blade plate plate body, closer to organization of human body, meets human anatomy and biomechanics characteristic, can reduce post-operative complication while reducing wound, improves clinical efficacy.Bionic structure of the present invention, convenient and flexible operation, accurate positioning, helical structure and lock screw, in conjunction with dual Titanic micro-plates, can effectively improve operation usefulness.

Detailed description of the invention

As shown in Figure 1 and Figure 2, this spiral type elastic bone plate more can fitted with long bone of limbs 3 is a strip plate body 1, spaced apartly on the plate face of strip plate body 1 be provided with screw 2, the two ends of plate body 1 reversely rotate bending respectively, revolve the plate body after folding 1 and form a spiral type.

Use procedure of the present invention is identical with fracture bone plate, in fracture reduction operation, form its axis of the present invention after closely fit at the fracture site of long bone of limbs 3 and circular surface of bone should keep being the angle close to right angle with fracture line, screw in screw in the screw 2 of spiral type strip plate body 1 of the present invention holding fracture site two ends after, long bone fracture osteopathy can be completed.

Claims

1. a spiral type blade plate, it is a strip plate body, spaced apartly on described plate body plate face is provided with screw, it is characterized in that described plate body two ends form a spiral type after oppositely revolving folding respectively.
