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 16, a kind of porous tantalum tantalum stick is provided with elastic piece 1-1, elastic piece position in the side wall of tantalum stick 1 It is connect in one end of tantalum stick medium position, elastic piece with tantalum stick side wall, the other end is towards tantalum club head direction, in the bottom of tantalum stick With spine 1-3.
The shape protrusion 1-2 that cleaves is provided on elastic piece.
The tantalum stick further includes the protection pipe 1-3 for accommodating tantalum stick, is made of titanium alloy, the both ends open of protection pipe, inner cavity Hollow, wherein protection pipe is the one third of tantalum stick length, and the protection pipe surface is provided with through-hole.
The outer wall of tantalum stick is provided with elastic piece, and the tail portion of elastic piece, will not shadow when placing towards the cephalad direction of tantalum stick It rings, elastic piece can be against on the inner wall got into the cave after filling, and wave-like protrusions can be in order to which histocyte be from getting into the cave on elastic piece Inner wall grows into elastic piece, and then regenerates and grow on tantalum stick.
Tantalum stick bottom end is provided with spine 1-3, and when placing tantalum stick, spine can be pierced into the bottom end got into the cave, and in point Thorn has concave point 1-4 above, spreads on tantalum stick convenient for bone marrow cell along spine, and the success rate of tantalum stick treatment can be improved.
The effect of protection pipe will can be first protected before surgery for protecting tantalum stick not to be broken during filling in On tantalum stick, position selects to can be the top, middle part or lower part of tantalum stick protective pipe sleeve, then taps to enter by tantalum stick again and get into the cave It is interior.After tantalum stick is fully inserted into and gets into the cave, tantalum stick is covered using broken bone and is buried, biggish dynamics is at this moment needed to tap, protected Pipe can protect tantalum stick to be not forced and fracture, and have through-hole 1-5 on tantalum stick, it is ensured that histiocytic growth, Bu Huiyin The isolated cell for protection pipe.
The tantalum stick further includes carrying out clean cleaning device to the inner wall of protection pipe, and wherein cleaning device includes pedestal 2, It is provided with the groove for placing protection pipe tube body on pedestal, is respectively arranged in the two side walls of pedestal into hole and is portalled, into hole It is corresponding with two openings of protection pipe tube body with portalling, saddle 4 is provided on the side wall into below hole, into setting above hole It is equipped with crush-cutting device 3, rocking bar 5 and cleaning band storing apparatus 6 are additionally provided on the side wall into hole side, in the side wall of side that portals On be provided with lift plate 8 and dustbin 7；
Cleaning device further includes cleaning band, and wiping villus is provided on cleaning band, also has the T-type being staggered on cleaning band First 10 and resistance knot 11；
Crush-cutting device includes accommodating chamber, and limit film 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 in limit film, and the rear portion of accommodating chamber is provided with slice 3-2, crush-cutting device Top setting there are two linear motor, the telescopic rod of two linear motors is respectively used to pushing and control slice to gravitation ball 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 rotating electric machine of rocking bar, rocking bar top has square hole；
Lift plate is arranged diagonally downward, and the end of lift plate is provided with 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 is removed from protection pipe, then protection pipe is placed into the groove on cleaning device pedestal, made Two of protection pipe openings respectively with connecting on base side wall into hole and outlet, cleaning band is accommodated from cleaning band then and is filled Interior pull-out to be set, is placed on saddle, single-chip microcontroller controls linear motor and depresses telescopic rod, and the extruding of the lowermost gravitation ball falls into mouth, It falls into mouth deformation and supports big, the decline of such gravitation ball, the T connector on cleaning band is squeezed into the T-slot of gravitation ball, then presses The empty gas entering opening that contracts 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 biggish gap or hole in protection pipe, since compressed air velocity ratio is larger, 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 controls rocking bar and 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 single-chip microcontroller, which controls compressed air, to be stopped, and due to the effect of gravity, gravitation ball can be moved 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, single-chip microcontroller control is waved Bar is downward, and gravitation ball is promoted, and since lift plate is arranged 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 is moved to topmost, repeatedly, clearly Clean band meeting side-to-side movement, side-to-side movement so just will use the villus on cleaning band to clean to tubular body, 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 single-chip microcontroller controls the decline of linear motor output rod, pressure Second T connector of another gravitation ball, cleaning band is snapped into the T-slot of gravitation ball, and then, single-chip microcontroller controls straight-line electric Machine declines slice, cuts off cleaning band, since the effect of gravity is fallen into dustbin, cleanup crew takes such first segment cleaning band Lower tube body, so that it may 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 single-chip microcontroller by automated cleaning tube body again Opening compressed air pushes gravitation ball to pass through tube body, and after hindering knot and leaving rocking bar range, rocking bar is by rotating to initial water Prosposition such as sets at next resistance knot to be blocked, and then step described above is cleaned repeatedly.The cleaning of such pair of tube body It can do and automatically complete, improve clean efficiency, reduce the time of medical staff.
