Abstract
The utility model belongs to the technical field of medical instruments and particularly relates to a combined type steel plate used for fracture of distal clavicle. The combined type steel plate comprises plate bodies and a plurality of bolt holes distributed on the plate body; the plate bodies comprise an outer side plate body and an inner side plate body; when being viewed from the front side, the outer side plate body for fixing the fracture far end takes the shape of an equilateral triangle, one bottom edge faces to the outer side, and a top end opposite to the bottom edge faces to the inner side and is connected with the inner side plate body to form a whole; the inner side plate is designed according to the shape of a 'reconstruction ribbon plate'; the bolt holes on the outer side plate body are distributed into two rows, wherein two to three holes are in the row close to the outer side, and one hole is in the row close to the inner side; and the bolt holes on the inner side plate body are uniformly distributed in a row. The combined type steel plate is designed according to the anatomical properties of fracture of distal clavicle, the arrangement of the bolt holes on the outer side plate body is favorable for fixing distal fracture fragments effectively, and the design of the 'reconstruction ribbon plate' of the inner side plate body is favorable for integral moulding of the steel plate, so that the steel plate can fit the clavicle surface more perfectly.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of blade plate that is used for clavicle outer end fracture.
Background technology
Clavicle is a long bone, is serpentine, and frame becomes unique bony framework between connection upper limb and the trunk between presternum and scapula.The medial extremity of clavicle links to each other with breastbone, forms sternoclavicular joint; Outboard end links to each other with acromion, forms acromioclavicular joint.The clavicle total length all can be touched subcutaneous, and wherein inboard 1/3 is thicker, is prismatic; In 1/3 thinner; And the outside 1/3 is flat-pack, and front and back are wide, thin up and down; Clavicular fracture is one of common damage of orthopaedics door, emergency treatment, accounts for 5% of whole body fracture; The clavicle outer end is owing to the particularity of anatomical structure, and this place's fracture is more common.
The internal fixation mode commonly used of clavicle outer end fracture has two kinds.A kind of is the tension band technology, and concrete grammar is to adopt Kirschner wire after the fixing fracture of the acromioclavicular joint in the outside, uses steel wire to be " 8 " font and on Kirschner wire, detours, tightens up.Tension band internal fixation technology is a kind of internal fixation method that the 2O quilt nineties in century " AO " school admits and recommends; Can effectively keep good para-position after the reduction of the fracture to line; But guaranteed trouble limb early functional exercise, reduced the generation of shoulder function complication, this technology biggest advantage is that operation technique is simple; Internal fixation is cheap and take out easyly, is a kind of clavicle outer end fractures method of basic hospital extensive use.Another kind method is a blade plate internal fixation technology, adopts fixedly clavicle outer end fracture of blade plate behind the fracture open reduction, and this fixed form is firm; Be difficult for making displacement fracture; Can obviously reduce the external fixation time, make the patient carry out functional exercise in early days, prevent joint accretion and amyotrophic generation.The maximum drawback of tension band technology is that the loosening incidence rate of Kirschner wire in the therapeutic process is higher, outwards moves to cause the fracture fixation failure easily, and inwardly displaced have the danger that causes nervus vasculairs under the clavicle or injury of lung.At present clinically be more prone to adopt the fixed mode of blade plate to treat clavicle outer end fracture, when reaching same fixed effect, avoided the loosening generation of inside-fixture.
As previously mentioned, because particularity that clavicle is dissected and patient's individual variation do not have at present and are adapted to the fixed anatomical plate in its outer end; Commonly used is the clavicle hook plate; During use steel plate hook is close to acromion back lower place cortical bone and inserts, steel plate is pressed in the clavicle surface, holes and is screwed into screw.Because acromioclavicular joint belongs to amphiarthrosis, still allow its fine motion after the clavicle hook plate is fixing, secular fine motion stress possibly cause the screw loosening of fixation steel plate and make the steel plate perk.Though it is better to be applied to the reconstruction plate plastotype property of limbs long cannon bone shaft, can't also not fit into clavicle outer end fixation of fractures at the enough screws of the far-end osteocomma fixing foot of fracturing.
In sum, the clavicle outer end fracture fixation mode of present clinical employing is unsatisfactory, and the tension band mode causes fixing failure easily; Though the clavicle hook plate has kept the mobility of acromioclavicular joint, the fine motion in this joint possibly cause the loosening of steel plate screw.
Summary of the invention
The purpose of this utility model be to provide a kind of easy and simple to handle, safety good, can be used for the combined steel plate of clavicle outer end fracture internal fixation.
The combined steel plate in clavicle outer end that this utility model provides is on the basis of the reconstruction band of present clinical use, to improve and obtain, and is processed by medical stainless steel or titanium alloy, repeatedly high-temperature sterilization.This combined steel plate is made up of plate body 1 and the some screw holes 2 that are distributed on the plate body 1, and wherein plate body 1 is divided into outside plate body 11 and inboard plate body 12 two parts again; From anterior view, the outside plate body 11 of fixing fracture far-end is the equilateral triangle shape, the one of which base toward the outer side, corresponding top, this base is towards the inboard, and joins with inboard plate body 12, forms an integral body; Inboard plate body 12 designs according to " rebuilding band " appearance.
In this utility model, the screw hole 2 on the outside plate body 11 is distributed as two row, classifies 2～3 holes as near one of the outside, and one of inboard is classified 1 hole as; Inboard plate body 12 is connected to form through screw hole 2 by some pitmans successively, and the length of said pitman is 0.5cm-0.8cm, and diameter is 0.2cm-0.4cm.
In this utility model, screw hole 2 designs can be locking or non-locking device line, and the screw hole internal diameter is 2.5mm-3.2mm.
The entire length of this utility model is 13 cm～20cm, and wherein, plate body 11 length of sides in the outside are 2cm-4 cm; The length of inboard plate body 12 is 10cm-17cm, and width is 1cm-1.5cm.
This utility model designs according to the anatomical features of clavicle outer end fracture; The screw hole layout of outside plate body 11 helps effective stationary remote sclerite; " rebuilding band " appearance of inboard plate body 12 is designed with and is beneficial to the steel plate HAVING A GRACEFUL FIGURE, makes it more to fit with the clavicle surface of bone.
