Invention content
The object of the present invention is to provide a kind of bone surgery tantalum bar device, protection tantalum stick will not crush during operation.
To achieve these goals, using following technical scheme：
A kind of bone surgery tantalum bar device, including tantalum stick, it is characterised in that：Described device includes the protection pipe for accommodating tantalum stick, protectsThere is hole, described device further includes a fastening nail, wherein fastening nail is followed closely to be made of ailhead and rivet nut two parts on pillarHead is an inclined inclined tab, and for angle for 90 degree, the section of tantalum stick is small upper greatly trapezoidal under one between ailhead and acrosomeStructure.
The ailhead is more than hole.
Described hole and fastening nail are two sets, respectively positioned at the both sides of protection pipe.
Described hole is located at the middle position of protection pipe.
Described hole is located at the position on protection pipe top 3/4ths.
The protection pipe and fastening nail are that titanium alloy is made.
Present invention employs one layer of fender bracket of external package in tantalum stick, so design can ensure that tantalum stick is pre- in implantationIt will not be crushed during buried via hole, ensure the integrality of tantalum stick.Fastening nail so that protection pipe is firmly fixed in hole, protect by guaranteeThe stability of pillar.

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 device, including tantalum stick 1-1, described device includes accommodating tantalum stickProtection pipe 1-2, there is hole 1-3, described device further includes a fastening nail 1-4, wherein fastening nail is by following closely in protection pipeHead and rivet nut two parts composition, ailhead is an inclined inclined tab, and angle is not 90 degree between ailhead and acrosome, the section of tantalum stickIt is small big trapezium structure under one, ailhead is more than hole.Hole and fastening nail are two sets, respectively positioned at the two of protection pipeSide, hole are located at the middle position of protection pipe.
In use, first will fastening nail be inserted into hole in, make ailhead at an acute angle with protection pipe, be then inserted into tantalum, it is upper greatly underSmall tantalum stick can will fasten the extruding of nail gently, then protection pipe is put into together with tantalum stick in drilling after being gently inserted into, by protection pipeIt puts to behind bottom, presses tantalum stick with strength, tantalum stick is allowed to reach bottommost, at this moment the side wall of tantalum stick can squeeze ailhead, by rivet nut jailThe insertion drill hole inner wall in jail, thus, which protection pipe is firmly fixed in drilling.
The bone surgery tantalum bar device 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 fastening nail is taken out, protection pipe is placed into the groove on cleaning device pedestal so that protection pipeTwo openings connect respectively on base side wall into hole and outlet, then pull out cleaning band out of cleaning band storing apparatus,It is placed on saddle, microcontroller control linear motor pressure telescopic rod, the lowermost gravitation ball extruding falls into mouth, falls into mouth deformationSupport is big, the decline of such gravitation ball, and the T connector on cleaning band is squeezed into the T-slot of gravitation ball, and then compressed air is into holeSpray compressed air, push gravitation ball drive cleaning band overcome the pulling force of wind spring in clean bag storing apparatus and along protection pipe pipeBody moves, although having larger gap or hole in protection pipe, since compressed air flow velocity is bigger, as well as gravityThe diameter of ball is directly matched with tube body, therefore gravitation ball also can be than more smoothly advancing in tube body, and microcontroller control is shakenSwing rod keeps horizontal, and clean bag is slowly passed through out of rocking bar square hole, and when gravitation ball, which moves to, to portal, gravitation ball drops out,Microcontroller control compressed air stops, and due to the effect of gravity, gravitation ball can move downward, and after it have passed through lift plate, fall intoDustbin.The slightly smaller square hole of resistivity knot on rocking bar can block resistance knot, and then, microcontroller control rocking bar is downward, weightPower 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, and so repeatedly, cleaning band can be leftRight movement, side-to-side movement so will clean tubular body using the villus on cleaning band, after being repeated several times justIt can be clean.
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.
