Abstract
The utility model belongs to the field of medical equipment, which relates to a clavicle previa anatomical bone plate for treating clavicular fracture, and is formed by a bone plate main body (1) and a hasp (2), wherein the hasp is arranged on an acromial end of the bone plate main body, and an included angle between the bone plate main body and the hasp are in 85 degrees to 95 degrees. The lateral surface of the bone plate main body is in a wave shape, which adapts to dissect physiology morphology of a clavicle (3), and the bone plate main body and the hasp are both provided with a long circular counterbore. When fracture fragments are fixed, the bone plate main body is arranged above the clavicle, and the hasp is arranged above the clavicle. Compared with the prior art, the clavicle previa anatomical bone plate has higher fixed strength and shear resistance level, which can dramatically lower damage risks to important vascular nerve and pleura, is beneficial for fracture healing, and whose clinical application is more convenient and flexible and actual application gets an excellent clinical effect.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of orthopaedics property implanted product, is specifically related to be used for the treatment of the preposition anatomical form blade plate of clavicular fracture.
Background technology
The clinical treatment clavicular fracture often adopts the bone property implanted product at present, and the prior art relevant with this utility model has S type clavicle blade plate.Described S type clavicle blade plate profile front is " S " type (Fig. 3), and top screw hole is round counterbore.When clinical practice, S type clavicle blade plate place clavicle the top---normotopia is fixed.This product adopts implants property rustless steel or titanium alloy material, by line cutting, thermoforming, machined such as bore, mill and form, mainly is applicable to the fixation for treatment that resets of clavicular fracture.
Clinical application practice shows that S type blade plate remains in following defective: the first, and because of being subjected to the shearing of above-below direction, S type clavicle blade plate is easy to generate bending or screw fixedly gets loose, even situation such as blade plate fracture occurs, causes fractures to be failed; The second, because individual variation, S type blade plate still needs to a certain degree moulding in actual use, and this side direction is moulding may to cause blade plate intensity to reduce and the nail bore deformation, directly influences the quality of using and perform the operation of blade plate; The 3rd, follow closely rounded hole, hole, limited the entry point of screw, can't add press fit; The 4th, because blade plate places the clavicle top, boring, tapping action etc. are to be carried out from top to bottom, causes the damage of vital tissues such as arteriovenous under the clavicle, brachial plexus nerve, pleura easily.In addition, traditional blade plate places the clavicle top, and protuberance is obvious on build slight of stature person's body surface, thereby influences attractive in appearance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and defective, provides a kind of clavicle preposition anatomical form blade plate.
The preposition anatomical form blade plate of this utility model clavicle is to improve on the basis of common clavicle blade plate, mainly addresses the problem: 1, reduce product and bending or fracture occur, reduce the possibility that screw fixedly gets loose; 2, design the more anatomical form blade plate of coupling, and solve the problem of possible moulding reduction armor plate strength; 3, solve the problem that screw advances to follow closely the position limitation, can provide pressurization during the bone fixation folded block, the healing that is more conducive to fracture; 4, reduce the risk of vital tissues such as damage important blood vessels nerve, pleura in the operation.
This utility model adopts the property implanted rustless steel or titanium alloy material to make the preposition anatomical form blade plate of clavicle.The preposition anatomical form blade plate of this clavicle is made of main body (1) and hasp (2), described hasp partly is positioned at the acromial end of blade plate main body, during the bone fixation folded block, described blade plate main body places clavicle (3) the place ahead, and hasp partly is positioned at the clavicle top, and the angle of described main body and " hasp " is 85 °-95 °.Described blade plate main part side undulate adapts with the dissect physiology form of clavicle, and the blade plate main body is provided with 4-12 screw fixed hole, and hasp is partly established a screw hole, and described screw hole is Long Circle counterbore (Fig. 1, Fig. 2).
This utility model meets the designing requirement of YY0017 " Osteosynthetic implants metal bone fracture plate ".
The design feature of this blade plate is: first, with product design is the preposition blade plate of clavicle, it is stressed that the shearing up and down that steel plate is suffered changes lateral thrust into by the front flexural loading, can improve its anti-intensity of shear, can select for use simultaneously longer screw to carry out the fixing of fore-and-aft direction, strengthen hold, reduce the possibility of screw loosening; The second, product design becomes anatomical form, meets the anatomic form of clavicle fully, even need steel plate is carried out slight positive moulding under a few cases, can the intensity of product not exerted an influence, and screw hole can not be out of shape yet; The 3rd, the normotopia hasp of blade plate shoulder lock end partly makes sclerite obtain three-dimensional fixation, and is fixing more firm; The 4th, the screw hole of this blade plate is a slotted hole, can increase the alternative of entering to follow closely the position, can make fixedly the time fracture end produce pressurization simultaneously, is beneficial to union of fracture.
This utility model adopts the property implanted rustless steel or titanium alloy material, processing mode by the blade plate of routine preparation at present, by line cutting, thermoforming, machined such as bore, mill and make the preposition anatomical form blade plate of clavicle, through tests such as corrosion resistance test, the detection of product torn grain and hardness tests, the result shows, meets clinical requirement safe in utilization.
The preposition anatomical form blade plate of this clavicle is compared with prior art S type clavicle blade plate through zoopery and clinic trial, has following advantage:
1. have higher constant intensity and shearing resistance level, and improved reliability of products;
2. can significantly reduce the risk of vital tissues such as damage important blood vessels nerve, pleura;
3. the pressurization of slotted hole helps union of fracture;
4. the anatomical form design makes clinical practice more convenient flexibly;
5. this blade plate preposition fixing remedied the fixed S type of normotopia clavicle blade plate well and swelled on build slight of stature person's body surface obviously, influences defective attractive in appearance.
