Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to fast-open type and opens the breast reduction fixture device.
Background technology
At present, when doing Thoracic surgery, opening the approach in thoracic cavity, generally is that breastbone is vertically cut from the centre, after the operation, be the both sides punching of longitudinal cut in the middle of breastbone to the fixing means of breastbone, before breastbone is closed, in the hole, put on steel wire, after breastbone is closed, again steel wire is tied up one by one.Because the respiratory movement of pulmonary has an expansionary force to breastbone, the binding so steel wire will pressurize if steel wire bundle is loose, under the effect of breathing expansionary force, makes the breastbone longitudinal cut split easily, does not have fixing effect, is unfavorable for healing.If steel wire bundle is too tight, careless steel wire fracture, not only this binding fixing point can not use, and the steel wire of fracture might damage infrasternal important organ, causes malpractice.Thereby doctor's operating technology had relatively high expectations, certain risk is arranged.Chinese patent 200520078272.X Encirclement type breast bone plate, 200820114940.3 1 kinds of bone fracture plate of memory alloy for breastbones of Chinese patent, overcome to a certain extent the defective of steel wire bundle, but brought new defective, be exactly again to open breast to pull down relatively difficulty of this bone fracture plate for breastbone, holding time is more.If in case of emergency, need to open breast and rescue this patient, can cause very serious consequence.
Goal of the invention
The purpose of this utility model is opened the breast reduction fixture device with regard to providing a kind of fast-open type easy to loading and unloading.
The solution that realizes this utility model purpose is to comprise encircling arm, particularly left fixing head 1 is provided with a left side and encircles arm, correspondence is provided with the right side and encircles arm on the right fixing head 3, be provided with prolate shape through hole 9 on the left fixing head 1 and in the middle of on the right fixing head 3, fixed knob 4 is installed in the prolate shape through hole 9, the two ends of left fixing head 1 respectively is provided with a block 2, two encircle that a side is provided with hasp 7 between the arm on the left fixing head 1, opposite side is provided with block 11, two block 11 places that encircle corresponding left fixing head 1 between the arm are provided with breach 6 on the right fixing head 3, breach 6 is provided with inside inclined-plane 10, and long limit one side of prolate shape through hole 9 is provided with two projections 5 on the right fixing head 3.
Fixed knob 4 is I-shaped shapes, and the distance between the two boards is equal to, or greater than the thickness sum of left fixing head 1 and right fixing head 3 up and down.The centre of fixed knob 4 is provided with hole 8, and hole 8 is through hole or blind hole.The shape in hole 8 is rectangles or square or oval.
Left side on the left fixing head 1 encircles on arm and the right fixing head 3 the corresponding right side and encircles arm and have two groups at least.
The utility model has the advantages that: 1, adopted the marmem making, so that fracture reduction operation is easy; 2, rational in infrastructure, be fit to fixing breastbone.3, fixedly plus-pressure is stable, can not become flexible because of the bone resorption of breastbone wound surface, simultaneously difficult drop-off.4, left and right sides fixing head all has through hole, has reduced the blood fortune of breastbone is blocked, and is conducive to the blood circulation of the myocardial revascularization of breastbone and the soft tissue above the breastbone, has shortened healing cycle.5, adopted Split type structure, easy to loading and unloading.6, Split type structure is rationally fixed.

The specific embodiment
This utility model is comprised of three memorial alloy parts, it is left fixing head 1, right fixing head 3 and fixed knob 4. left fixing heads 1 are provided with a left side and encircle arm, correspondence is provided with the right side and encircles arm on the right fixing head 3, be provided with prolate shape through hole 9 on the left fixing head 1 and in the middle of on the right fixing head 3, fixed knob 4 is installed in the prolate shape through hole 9, the two ends of left fixing head 1 respectively is provided with a block 2, two encircle that a side is provided with hasp 7 between the arm on the left fixing head 1, opposite side is provided with block 11, two block 11 places that encircle corresponding left fixing head 1 between the arm are provided with breach 6 on the right fixing head 3, breach 6 is provided with inside inclined-plane 10, and long limit one side of prolate shape through hole 9 is provided with two projections 5 on the right fixing head 3.
Fixed knob 4 is I-shaped shapes, and the distance between the two boards equals or be slightly larger than the thickness sum of left fixing head 1 and right fixing head 3 up and down.The centre of fixed knob 4 is provided with hole 8, and hole 8 is through hole or blind hole.The shape in hole 8 is rectangles or square or oval.Instrument rotation fixed knob 4 easy to use.
During operation, breastbone is vertically cut from the centre, after open chest surgery is finished, select sizeable this utility model, at this moment left fixing head 1 and right fixing head 3 install, and fixed knob 4 is put into prolate shape through hole 9, fixed knob 4 90-degree rotations, left fixing head 1 and right fixing head 3 is further fixing.Then cooling, because this utility model is made with memorial alloy, will deliquescing after the cooling, be easily installed in like this on patient's the breastbone, when reaching body temperature along with the raising of temperature, under the effect of memorial alloy, this utility model returns to original shape, has so just fixed patient's breastbone.
Patient of the present utility model has been installed, if need again urgent open chest surgery, dismounting this utility model rotates 90 degree with instrument with fixed knob 4 first, from prolate shape through hole 9, take out fixed knob 4, pry open right fixing head 3 with instrument from the inclined-plane 10 of breach 6 again, left like this fixing head 1 and right fixing head 3 have just unloaded from the both sides of breastbone, have finished soon dismounting.
