[0020] 本发明的工作原理如下: [0020] The working principle of the present invention is as follows:

[0021]如图1所示,内爪I具有两个长方孔,在两个长方孔之间间留一间距,并在这个间距处设置有一凸块,使该凸块作为设计安装工具持住锁紧固定用。 [0021] 1, the pawl having two rectangular apertures I, leaving a distance between the rectangular hole between the two, and arranged in this spacing has a protrusion, so that the bump as a design tool for installation hold of locking fixing. 外爪2具有两个侧壁,并且侧壁的中部具有一凹槽,通过上述结构,本胸骨合拢固定器安装工具把用凹槽进行左右定位、上下用侧壁夹持定位控制。 Outer claw 2 has two side walls, and side walls having a central recess, by the above-described configuration, the present sternal closure installation tool holder with a recess for the left and right positioning, holding the side walls with vertical positioning control.

[0022]本发明利用内爪锁松钮12上的锁松片12-1的厚薄在定位活动杆5下面的内爪撑开弹簧13作用下,使其在锁松片12-1厚薄变化时达到松开、夹紧,当本安装工具需固定内爪I时,在内爪锁松钮12的内爪锁松扭拨杆12-2往下一推,利用锁松片12-1由厚变薄,通过弹簧力使球头销5-1的球头贴紧锁松片12-1,使定位活动杆5撑开,此时定位活动杆5及定位固定杆4下面的内爪作用部就能顺利地插入到内爪I的中间固定孔中,当要锁紧时内爪锁松钮12的内爪锁松扭拨杆12-2往上提时,锁松片12-1由薄变厚利用杠杆原理使定位活动杆5上面撑开,下部收紧、夹紧内爪I的内孔达到夹紧了内爪I的作用;固定外爪2的方法与固定内爪原理基本相同,它利用外爪2两侧斜面及中间设计的一凹槽,利用凹槽作定位夹住斜面使左右、上下都得到了固定,通过拨动外爪锁松钮14的外爪锁松扭拨杆14- [0022] With the present invention, the lock pawl lock release button 12 on the loose sheet thickness 12-1 spreader pawl 13 is positioned in the action of the spring 5 below the movable rod, so that when the latch 12-1 loose sheet thickness variation reach the release and clamping, when the present tool is mounted to be fixed inner claw I, including the pawl lock release button 12 of the loose twist lock pawl lever to push down a 12-2, 12-1 by the use of locking pine sheet thickness thinning, by the spring force so that the ball head of the ball stud affixed locked 5-1 12-1 loose sheets, the movable rod 5 the positioning distraction, when the movable rod 5 is positioned and fixed with 4 positioned below the pawl portion lever action when the intermediate can be smoothly inserted into the fixing hole in the jaw I, when the locking pawl to lock the lock release button 12 of the pawl release lever twist put up 12-2, 12-1 from a thin locking plate loose thickening of the positioning principle of leverage stretched above the movable rod 5, the lower portion of the tightening, the clamping jaws within the inner bore of the clamping effect I reaches the inner claw I; a method of fixing the outer fixed jaw 2 and the principle of the pawl is substantially the same, it uses an outer claw 2 and the intermediate slant grooves on both sides of the design, the concave groove for positioning the right and left sandwiching the inclined surface, and down have been fixed, through the outer dial lock outer claw lock pawl release lever knob 14 twisted loose 14- 2使凸轮14-1上圆心距变化,凸轮14-1压在一外定位活动片7上,另一件为外定位固定片6,两片之间设计一外爪撑开弹簧15,当外爪锁松扭拨杆14-2往前推时,凸轮14-1的圆心距缩小,通过下面两片间外爪撑开弹簧15的作用,两片下面松开,此时外爪2可顺利轻松地放入其固定片中,此时拉动外爪锁松扭拨杆14-2,凸轮14-1轴心距由小变大,凸轮14-1压紧外定位活动片6,外定位活动片7往里收缩,两片间距缩小,外爪2即被夹紧,由于采用的是杠杆原理锁紧固定要比小螺钉的力更大,以上此原理比起原安装工具不需拧螺丝安装拧螺丝卸下,只需拉、推拨杆即可达到装卸固定,即简单又方便又牢固,也不可能在手术中发生意外,影响手术。 2 that the center distance variation on the cam 14-1, 14-1 pressed against a cam positioning activities outer sheet 7, the other outer sheet 6 is positioned and fixed, a design between the two outer spreader pawl spring 15, when the outer twist lock pawl release lever pushed forward 14-2, 14-1 of the cam from the center out, the pawl 15 by the expansion action of the spring between the two outer next, release the two following, this time may be smoothly outer claw 2 easily fixed into the sheet, pulling the outer case lock pawl release lever twisting 14-2, 14-1 cam axial distance from small to large, the pressing cam 14-1 movable blade 6 is positioned outside the outer positioning activities shrinkage sheet 7 inside, two narrow pitch, i.e., the outer clamping jaws 2, thanks to the principle of the locking lever is greater than the fixing screw force, this principle more than the original installation tool to install without screwing Remove screwing, simply pulling, pushing lever detachably fixing can be achieved, that is simple and convenient and secure, it is impossible in the accident surgery, affect the operation.

[0023]另外,通过驱动机构,也就是旋转旋钮9,带动齿轮10在齿条8上移动,从而可以使其中一个牵开臂3相对于齿条8移动,从而可以控制内爪I和外爪2之间的距离,调节打开胸骨的宽度,止回机构可以限制相应的牵开臂3在齿条8上移动,从而保证胸骨合拢固定器固定胸骨的可靠性和稳定性,按下按钮11-2,可使勾部11-1与齿条凹槽脱离,两个牵开臂3又可以相对齿条8移动,将两个牵开臂3调整至齿条8上适合位置处,实现松紧可控,待胸骨合拢固定器锁紧后,将本安装工具与胸骨合拢固定器分离。 [0023] Further, by the drive mechanism, i.e. rotation of the knob 9, movement of the rack 10 drives the gear 8, so that one can make the retractor arm 3 relative to the rack 8 moves, can be controlled within the jaws and outer jaws I the distance between the two, adjusting the width of the sternum open, non-return mechanism may limit a respective retractor arm 3 is moved on the rack 8 so as to ensure reliability and stability of the sternum closure of the sternum fixation device, press the button 11- 2, can hook groove portion 11-1 from the rack, and two retractor arms 3 can move relative to the rack 8, the two retractor arms 3 to adjust the rack 8 at a suitable position, can be implemented elastic after control, the lock holder to be closed sternum, the present installation tool holder separated sternum closed.
