Description
Technical field
The present invention relates to medicine equipment, particularly a kind of easy-dismount breastbone bone fracture device.
Technical background
The technology such as generally use in thoracic surgery at present that wire binding, Kirschner wire are fixed, steel plate is fixed and synthetic resin is fixing, in the time doing thoracic surgery, due to the needs to patient treatment, needs breastbone along midline incision sometimes. After having performed the operation, again breastbone is tied up with stainless steel wire or Kirschner wire is fixed. When fixing, punch on the both sides of middle the longitudinal cut of breastbone, in hole, put on steel wire, after breastbone is closed, then steel wire is tied up. Breastbone belongs to flat bone, easily displacement, and due to the respiratory tension force of lung, be difficult to control the binding dynamics of steel wire. The too pine of binding does not have fixing effect, what bundle is too tight, easily make steel wire fracture, longitudinal steel wire is easily torn breastbone, and steel wire is easily loosening, causes the serious adverse consequences such as breastbone healing is bad, healing delay, and after breastbone healing, steel wire is also difficult for taking out, and may be damaged to infrasternal vitals, causes malpractice. Steel plate is fixing more firm, but needs boring, easily damages organ after breastbone, cell reaction easily occurs, and need second operation to take out steel plate; Synthetic resin has can absorption characteristics, does not need second operation to get fixture, but it need insert in ossis when fixing, easily occur infecting, and fixed effect is not firm. When above-mentioned operation technique is fixing, difficulty is larger, and operating time is longer, the more important thing is the rear difficulty of taking out of healing, if misoperation also can hurt internal organs under chest.
Apply for and disclose a kind of bone fracture plate of memory alloy for breastbone (application number: 200820114940.3, the applying date: on May 8th, 2008, Granted publication day: on April 8th, 2009) for above-mentioned technical problem the applicant, constant intensity and connective stability are significantly improved, but when above-mentioned patent dismounting, need cold compress bone plate, and coordinate ripping bar to pry open one by one claw with special pliers, unloading process very complicated, need medical personnel to possess certain operating experience, smoothly dismounting bone plate. In emergency circumstances some critical cases need to be opened chest rescue, and slightly careless manipulation will bring injury to sufferer, loaded down with trivial details consuming time the living forever in certain risk of unloading process simultaneously, and serious meeting directly jeopardizes sufferer life.
Summary of the invention
The object of the present invention is to provide a kind of easy to loading and unloading, simple operation, fixed easy-dismount breastbone bone fracture device.
The technical solution adopted for the present invention to solve the technical problems is:

On described left plate and right plate, offer jack, every group of breastbone bone fracture device connects to form many group breastbone bone fracture devices by jack and double-leg nail.
The left plate of described single group breastbone bone fracture device also can be connected with the left plate of another group breastbone bone fracture device with joint pin by connecting hole.
Described splicing groove is rhombus groove, square groove, semi-circular groove or swallow tail shaped slot, and spelling joint is suitable with splicing groove.
On described left plate, be at least provided with a splicing groove.
On described left plate, be at least provided with one and encircle arm, right plate is at least provided with one and encircles arm.
Described left plate and right plate are provided with fixed pin holes, and fixed pin holes is connected with steady pin.
Described left plate and right plate are provided with dismounting groove.
The Mosaic face of described splicing groove and spelling joint is for facing directly or inclined-plane.
Beneficial effect of the present invention is: 1, easy-dismount breastbone bone fracture device comprises left plate and right plate, left plate and right plate are respectively equipped with encircles arm, on left plate and right plate, be respectively equipped with splicing groove and spelling joint, splicing groove and spelling joint are spliced to form single group breastbone bone fracture device. The installation of breastbone bone fracture device Rapid Combination is convenient in being provided with of splicing groove and spelling joint. 2, single group breastbone bone fracture device can be connected to form many group breastbone bone fracture devices by double-leg nail or joint pin, can increase and decrease according to the concrete fixed position of sufferer. 3, left plate and right plate are provided with fixed pin holes, after splicing groove and spelling joint are fastened, insert steady pin along fixed pin holes, significantly promote bonding strength. 4, left plate and right plate are provided with dismounting groove, first extract steady pin when dismounting, by crowbar insert dismounting groove a little the application of force just can easily separate left and right side plate and complete dismounting. 5, can use double-leg nail and joint pin to be fixed connection simultaneously, can play dual fixed effect, further promote the intensity of bone fracture device.

Detailed description of the invention
As Fig. 1,2, as shown in a kind of easy-dismount breastbone bone fracture device, comprise left plate 1 and right plate 2, left plate 1 and right plate 2 are respectively equipped with encircles arm 3, is respectively equipped with splicing groove 4 and spelling joint 5 on left plate 1 and right plate 2, and splicing groove 4 and spelling joint 5 are spliced to form single group breastbone bone fracture device.
As described in Fig. 3,6 and 10, on left plate 1 and right plate 2, offer jack 6, every group of breastbone bone fracture device is by jack 6 and the many groups of double-leg nail 7 composition breastbone bone fracture device. The left plate 1 of described single group breastbone bone fracture device can also be connected with the left plate 1 of another group breastbone bone fracture device with joint pin 9 by connecting hole 8. The connector of joint pin 9 can be square spigot, rounded nose or thread head. Need to improve the intensity of bone fracture device time, use double-leg nail and joint pin 9 to be fixed connection simultaneously, play dual fixed effect.
Described splicing groove 4 is rhombus groove, square groove, semi-circular groove or swallow tail shaped slot, and spelling joint 5 is suitable with splicing groove 4. On described left plate 1, be at least provided with a splicing groove 4. On described left plate 1, be at least provided with one and encircle arm 3, right plate 2 is at least provided with one and encircles arm 3.
Left plate 1 and right plate 2 are provided with fixed pin holes 10 as shown in Figures 4 and 5, and fixed pin holes 10 is connected with steady pin 11. Described left plate 1 and right plate 2 are provided with dismounting groove 12. The Mosaic face of described splicing groove 4 and spelling joint 5 is for facing directly or inclined-plane, and Mosaic face while being inclined-plane, splices groove 4 and spelling joint 5 splicings fasten better tightness, and dismounting is also more convenient simultaneously.
When use, select breastbone bone fracture device group number according to the sufferer state of an illness, it is fully cooling that the bone fracture device that memorial alloy is made is put into 0-5 DEG C of brine ice, strut and encircle the rear implantation trouble of arm 3 bone by distraction forcep, the gauze hot compress bone fracture device soaking with about 45 DEG C sterilization hot salt brines again, utilize the deformation of material can tightly hold breastbone tightly, complete the installation of single group breastbone bone fracture device. Rear use double-leg nail 7 or joint pin 9 are installed to be by group connected each group, need to improve the intensity of bone fracture device time, use double-leg nail 7 and joint pin 9 to be fixed connection simultaneously, finally insert steady pin 11 by the installation that has been fixed together of left plate 1 and right plate 2. When dismounting, remove double-leg nail and joint pin 9, extract steady pin 11 out, by crowbar insert dismounting groove 12 a little the application of force just can easily separate left and right side plate and just can easily complete dismounting.
