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 stick Protection 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 pipe Head 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 stick It 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 pipe Side, hole are located at the middle position of protection pipe.To protection pipe internal protrusion there are one being also set up on the top of protection inside pipe wall Ring, described device further include an isolation board, and isolation board is placed on ring, and the protrusion is 1 millimeter.
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 under Small 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 pipe It 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 jail The insertion drill hole inner wall in jail, thus, which protection pipe is firmly fixed in drilling.Then isolation board is put into protection pipe Interior, broken bone is preferably played real plug in the top of protection pipe by isolation board for tantalum stick and broken bone to be isolated.
The bone surgery tantalum bar device is further included carries out clean cleaning device to the inner tube of protection pipe, wherein cleaning Device 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 into Hole and portal, into hole and portal corresponding with two openings of protection pipe tube body, saddle is provided on the side wall into below hole 4, 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 band First 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 chamber 1, the diameter of gravitation ball is matched with the diameter of protection pipe tube body, can gravitation ball be freed in and out in tube body, The T-slot for running through sphere is provided on gravitation ball, T connector is matched with T-slot, and the vertical slots of T-slot are stuck on banking stop, The rear portion of accommodating chamber is provided with slice 3-2, the top setting of crush-cutting device there are two linear motor, two linear motors it is flexible Bar is respectively used to the pushing to gravitation ball and the lifting of control slice；It is provided with made of elastic material in the bottom of accommodating chamber Mouth 9 is fallen into, the diameter for falling into mouth is slightly less than the diameter of gravitation ball；
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 pedestal Sliding 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 pipe Two 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 deformation Support 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 hole Spray compressed air, push gravitation ball drive cleaning band overcome the pulling force of wind spring in clean bag storing apparatus and along protection pipe pipe Body moves, although having larger gap or hole in protection pipe, since compressed air flow velocity is bigger, as well as gravity The 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 shaken Swing 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 into Dustbin.The slightly smaller square hole of resistivity knot on rocking bar can block resistance knot, and then, microcontroller control rocking bar is downward, weight Power 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 left Right movement, side-to-side movement so will clean tubular body using the villus on cleaning band, after being repeated several times just It 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 time In shape slot, lift plate rises to highest point, and entire cleaning band is tightened up, and microcontroller control linear motor output rod declines, pressure Another gravitation ball, second T connector of cleaning band are snapped into the T-slot of gravitation ball, then, microcontroller control straight-line electric Machine, 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 band Lower 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 upwards State avoids resistance knot, and if desired tube body, is just placed in the groove of cleaning device, then microcontroller by automated cleaning tube body again Opening 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 water Prosposition such as puts at next resistance knot to be blocked, and then step described above is cleaned repeatedly.Such cleaning to tube body It can do and automatically complete, improve clean efficiency, reduce the time of medical staff.
