Abstract
The invention discloses a fixing device for orthopedics. The fixing device comprises a plate body of which the inner surface is slightly in an arc shape, wherein an oxide ceramic coating layer, a glass coating layer or a porous titanium coating layer are sputtered on the surface of the plate body by ion beams; holes through which screws pass are formed in the plate body, and a medicine slowly releasing groove is formed in the inner surface of the plate body; the edge contour of the medicine slowly releasing groove is a curve, and the groove is filled with matrix type slowly releasing medicine; the medicine is slowly released in the human body. The fixing device for the orthopedics has the advantages that the curing procedures are reduced, the fracture healing time is shortened, the releasing speed of the medicine is controlled, the medicine for oral administration is reduced, the medical cost for patients is reduced, and the practicability of the fixing device is improved.
Description
Technical field
The present invention relates to a kind of orthopedic medical device, particularly a kind of Orthopedic fixation device.
Background technology
At present, in therapeutic process after skeleton fracture, the therapeutic modality of fracture is adopted on Orthopedic splint and bored a hole, be fixed in the mode by bone screw, should hole to the bone of fracture site like this, after boring, with multi-disc clamping plate, bone be clamped, and then clamping plate be fixed with screw, until after the healing of the bone of fracture site, then clamping plate and screw are taken out.And, in the process of the bone healing of fracturing, because clamping plate are only metals, can not carry out direct drug injection to the fracture site of skeleton, can only adopt innerlich anwenden thing to carry out auxiliary treatment, and such metal surface do not have activity, make the course of disease long, program is loaded down with trivial details, the shortcoming that bone healing is slow, cause patient suffering's cycle long, and innerlich anwenden thing has certain side effect, systemic administration can not be avoided, the urgent needs of extensive patients can not be met.
Summary of the invention
The problem to be solved in the present invention is: a kind of convenient fixing is provided and can reduces patient suffering, have an Orthopedic fixation device that fracture site is carried out to local dispenser simultaneously.
In order to solve the problems of the technologies described above, Orthopedic fixation device of the present invention, comprises plate body, and the inner surface of described plate body is slightly cambered surface, and the whole surface of described plate body is by ion beam sputtering one deck oxide ceramic coating, glass coating or porous titanium coating; On described plate body, be provided with the hole by screw, the inner surface of described plate body is provided with medicament slow release and puts groove; In described medicament slow release groove, be filled with matrix type slow releasing pharmaceutical; The edge wheel profile of described medicament slow release groove is curve; Described medicine slowly discharges in human body; Described pharmaceutical pack is containing the ingredient that is useful on bone healing and/or wound healing; The setting corresponding to fracture site of described groove, the quantity that fracture site arranges described groove is many, away from fracture site, described groove quantity is set few, and described drug release concentration is concentrated near fracture site; Described groove be shaped as circular trough; The substrate of described matrix type slow releasing pharmaceutical is organic silicon rubber; The material of described plate body can adopt titanium alloy or rustless steel; Described hole is screwed hole.
The beneficial effect that the present invention obtains is: reduced patient suffering, fracture site carried out to the dispenser of local speed change degree slow release simultaneously by finishing processing, carry out directly timesharing treatment of part, reach invigorate blood circulation, the effect such as blood stasis dispelling, promoting healing, thereby shortening healing time, reduce oral medication, reduce patient's medical expense, improved the practicality of device.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural profile schematic diagram of the present invention.
Detailed description of the invention
As illustrated in fig. 1 and 2, Orthopedic fixation device of the present invention, comprises plate body 1, and the inner surface of described plate body 1 is slightly cambered surface, and the whole surface of described plate body 1 is by ion beam sputtering one deck oxide ceramic coating 2, glass coating 3 or porous titanium coating 4; On described plate body 1, be provided with the hole 5 by screw, the inner surface of described plate body 1 is provided with medicament slow release and puts groove 6; In described medicament slow release groove 6, be filled with matrix type slow releasing pharmaceutical 7; Described medicine 7 slowly discharges in human body; Described medicine 7 includes the ingredient for bone healing and/or wound healing; The setting corresponding to fracture site of described groove 6, the quantity that fracture site arranges described groove 6 is many, away from fracture site, described groove 6 quantity is set few, and described medicine 7 release concentrations are concentrated near fracture site; Described groove 6 be shaped as circular trough; The edge wheel profile of described groove 6 is curve, there is no straightway, such curve can make medicine become drug release gradient at curved edge outline-shaped, the speed that is the release of drug release one way or another is all different, such rate of release distributes and has accelerated drug releasing rate, and straightway can not promote this gradient to form, drug releasing rate is not affected; The substrate of described matrix type slow releasing pharmaceutical 7 is organic silicon rubber; The material of described plate body 1 can adopt titanium alloy or rustless steel; Described hole 5 is screwed hole.
When fracture is fixed, first fracture is anaesthetized to sterilization, then under the irradiation of X-ray machine, the bone of fracture is resetted, after on corresponding with fracture site the medicament slow release groove 6 of plate body 1, through the hole 5 on plate body 1, plate body 1 is fixed on the bone of fracture by bone screw.Orthopedic fixation device of the present invention, has reduced treatment time, has controlled drug releasing rate, has avoided systemic administration, reduces oral medication, has reduced patient's misery, has improved the practicality of device.
Above concrete mode of the present invention is described.Be illustrative for the description of invention herein, thereby scope of the present invention should not be limited to above-mentioned detailed description of the invention.It will be apparent to one skilled in the art that in the situation that not departing from purport of the present invention or substitutive characteristics, above-mentioned detailed description of the invention is carried out to other distortion or change, also should be considered as protection scope of the present invention.
