Specific embodiment
The present invention is described further in the following with reference to the drawings and specific embodiments.
As shown in Fig. 1 to Figure 14, a kind of bone surgery tantalum bar system, including tantalum stick 1-1, the system comprises accommodate tantalum stickProtection pipe 1-2, on the wall of protection pipe setting symmetrical two protrusions 1-4 is provided in opening, is there are one opening 1-3System further includes the locking reed 1-5 of V-arrangement, and the both sides of reed are provided with and the corresponding blind hole of protrusion, and the section of tantalum stick is presented greatlyUnder small trapezium structure.The opening and reed have two sets, are symmetrically arranged on the wall of protection pipe.The system comprises appearancesReceive the protection pipe of tantalum stick, the both ends open of protection pipe, inner hollow is provided with salient point, salient point on the head end inner wall of protection pipeHeight for 1 millimeter, salient point is uniformly arranged in the inside of tube wall, in a ring structure.
In use, reed is mounted in opening first, then protection pipe is put into drilling, one end of reed is boredThe extruding another side of hole inner wall can be rotated into protection pipe, after pipe to be protected installs, then by tantalum stick be pressed into protection pipe, due toSmall big under tantalum stick, one side on the inside of reed can slowly be squeezed by tantalum stick, and another side can compress the inner wall of drilling, in this wayProtection pipe can be firmly fixed in drilling.Broken bone is finally tightly pressed against to the head end of protection pipe, at this time in tube wall protrusion andIt is compacted between broken bone, the presence of salient point is to ensure that beating real broken bone will not leak easily to preferably increase the associativity of broken boneGo out.
The bone surgery tantalum bar system is further included carries out clean cleaning device to the inner tube of protection pipe, wherein cleaningDevice includes pedestal 2, and the groove for placing protection pipe tube body is provided on pedestal, be respectively arranged in the two side walls of pedestal intoHole and portal, into hole and portal corresponding with two openings of protection pipe tube body, saddle is provided on the side wall into below hole4, into crush-cutting device 3 is provided with above hole, rocking bar 5 and cleaning band storing apparatus 6 are additionally provided on the side wall into hole side,Lift plate 8 and dustbin 7 are provided on the side wall for side of portalling；
Cleaning device further includes cleaning band, and wiping villus is provided on cleaning band, also T-shaped with being staggered on cleaning bandFirst 10 and resistance knot 11；
Crush-cutting device includes accommodating chamber, and banking stop 3-3 is provided in accommodating chamber, lays gravitation ball 3- vertically in accommodating chamber1, the diameter of gravitation ball is matched with the diameter of protection pipe tube body, and the T-slot for running through sphere, T connector are provided on gravitation ballIt is matched with T-slot, the vertical slots of T-slot are stuck on banking stop, and slice 3-2, crush-cutting device are provided at the rear portion of accommodating chamberTop setting there are two linear motor, the telescopic rod of two linear motors is respectively used to the pushing to gravitation ball and control sliceLifting；It is provided with made of elastic material in the bottom of accommodating chamber and falls into mouth 9, the diameter for falling into mouth is slightly less than gravitation ballDiameter；
The output shaft of the bottom connection electric rotating machine of rocking bar, rocking bar top has square hole；
Lift plate is set diagonally downward, and the end set of lift plate has wedge-like opening；The bottom of lift plate is stuck in the side wall of pedestalSliding slot in, lift plate can slide up and down in sliding slot；
Wind spring is provided in clean bag storing apparatus, the end of cleaning band connect with wind spring and then twines on wind spring；
Compressed air is being additionally provided with into hole into Kong Chu；
When in use, first reed from protection pipe is removed, then protection pipe is placed into the groove on cleaning device pedestal, madeTwo openings for obtaining protection pipe connect respectively on base side wall into hole and outlet, and then cleaning band is accommodated from cleaning band and is filledInterior pull-out to be put, is placed on saddle, microcontroller control linear motor pressure telescopic rod, the lowermost gravitation ball extruding falls into mouth,It falls into mouth deformation to support greatly, the decline of such gravitation ball, the T connector on cleaning band is squeezed into the T-slot of gravitation ball, is then pressedThe empty gas entering opening of contracting sprays compressed air, pushes gravitation ball that cleaning band is driven to overcome the pulling force of wind spring in clean bag storing apparatus and edgeProtection pipe pipe body movement, although having larger gap or hole in protection pipe, since compressed air flow velocity is bigger, simultaneouslyAlso due to the diameter of gravitation ball is matched with the direct of tube body, therefore gravitation ball also can be more single than more smoothly advancing in tube bodyPiece machine control rocking bar keeps horizontal, and clean bag is slowly passed through out of rocking bar square hole, when gravitation ball, which moves to, to portal, weightPower ball drops out, and microcontroller control compressed air stops, and due to the effect of gravity, gravitation ball can move downward, and have passed through liftingAfter piece, dustbin is fallen into.The slightly smaller square hole of resistivity knot on rocking bar can block resistance knot, and then, microcontroller control is wavedBar is downward, and gravitation ball is promoted, and since lift plate is set diagonally downward, when gravitation ball moves upwards, is blocked by lift plate,But at this point, lift plate meeting upward sliding, when rocking bar moves to bottom, lift plate moves to topmost, so repeatedly, clearlyClean band meeting side-to-side movement, side-to-side movement so will clean tubular body using the villus on cleaning band, repeatedlyIt can be clean after several times.
After clean, rocking bar is waved to the bottom of its rocking tendency, and gravity head is stuck in the wedge of lift plate at this timeIn shape slot, lift plate rises to highest point, and entire cleaning band is tightened up, and microcontroller control linear motor output rod declines, pressureAnother gravitation ball, second T connector of cleaning band are snapped into the T-slot of gravitation ball, then, microcontroller control straight-line electricMachine, which will be sliced, to be declined, and cuts off cleaning band, since the effect of gravity is fallen into dustbin, cleanup crew takes such first segment cleaning bandLower tube body, it is possible to carry out further disinfection.Rocking bar reversely rotates so that vertical shape of the rocking bar to square hole upwardsState avoids resistance knot, and if desired tube body, is just placed in the groove of cleaning device, then microcontroller by automated cleaning tube body againOpening compressed air pushes gravitation ball to pass through tube body, and after resistance knot leaves rocking bar range, rocking bar is by rotating to initial waterProsposition such as puts at next resistance knot to be blocked, and then step described above is cleaned repeatedly.Such cleaning to tube bodyIt can do and automatically complete, improve clean efficiency, reduce the time of medical staff.
