To achieve these goals, using following technical scheme：
A kind of orthopedic operating tantalum bar system, including tantalum stick, it is characterised in that：The system comprises accommodate tantalum stick protection pipe, The both ends open of protection pipe, inner cavity is hollow, and horizontal annulus is provided on the tube wall of the upper end of protection pipe.
Bolt hole is provided on the annulus.
The report pipe is made of titanium alloy.
The annulus and protection pipe are an integral structure.
The upper inner of the protection tube wall is provided with salient point.
Present invention employs one layer of fender bracket of external package in tantalum stick, so design can ensure that tantalum stick is pre- in implantation It will not be crushed during buried via hole, ensure the integrality of tantalum stick.Locking device is additionally provided on fender bracket, fender bracket can be locked And drilling, ensure the firm of fender bracket.

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 orthopedic operating tantalum bar system, including tantalum stick 1-1, the system comprises accommodate tantalum The protection pipe 1-2 of stick, the both ends open of protection pipe, inner cavity is hollow, and horizontal circle is provided on the tube wall of the upper end of protection pipe Ring 1-3.Screw hole 1-4 is provided on the annulus, the annulus and protection pipe are an integral structure, the protection tube wall Upper inner be provided with salient point 1-5.
In use, protection pipe is put into drilling first, screw hole is passed through to follow closely on bone with screw, in this way by protection pipe jail The fixation in jail, then tantalum stick is pressed into protection pipe, the top of real protection pipe is finally beaten with broken bone, the effect of salient point is in order to better Increase the friction between broken bone and protection pipe.
The orthopedic operating tantalum bar system is further included carries out clean cleaning device to the inner tube of protection pipe, wherein clearly Clean device includes pedestal 2, and the groove for placing protection pipe tube body is provided on pedestal, is respectively arranged in the two side walls of pedestal Into hole and portalling, into hole and portal corresponding with two openings of protection pipe tube body, support is provided on the side wall into below hole Platform 4 into crush-cutting device 3 is provided with above hole, is additionally provided with rocking bar 5 and cleaning band storing apparatus on the side wall into hole side 6, 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, and the T-slot for running through sphere, T connector are provided on gravitation ball It 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 chamber Top setting there are two linear motor, the telescopic rod of two linear motors is respectively used to the pushing to gravitation ball and control slice Lifting；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 ball Diameter；
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 reed from protection pipe is removed, then protection pipe is placed into the groove on cleaning device pedestal, made Two 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 filled Interior 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 pressed The 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 edge Protection pipe pipe body movement, although having larger gap or hole in protection pipe, since compressed air flow velocity is bigger, simultaneously Also 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 body Piece 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, weight Power 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 lifting After 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 waved Bar 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, clearly Clean band meeting side-to-side movement, side-to-side movement so will clean tubular body using the villus on cleaning band, repeatedly It 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 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.
