Specific embodiment
The present invention is described further in the following with reference to the drawings and specific embodiments.
As shown in figs. 1 to 14, the bottom of a kind of medical porous tantalum tantalum stick, medical porous tantalum tantalum stick has an arc recessed
Slot 1-1, wherein the edge of arc groove is located at medical porous tantalum tantalum stick bottom outer wall, also sets up in the edge of arc groove
There is spine 1-2, wherein spine is crescent moulding, and the curvature of two arcs is different, the inside radian close to tantalum stick center
Curvature is larger, and the inside arc of all spines forms the small shape in the big lower part in a top.
Before filling in and getting into the cave by tantalum stick, first the broken bone in part is placed into the arc groove of tantalum stick bottom, the groove of arc
The small cavity in the big lower part in a top is formed with the inside arc of spine to be combined, and broken bone is accommodated completely, it is ensured that broken bone will not leak
Out, the normal implantation process for influencing tantalum stick, after the implantation of tantalum stick, the broken bone in bottom groove receives extrudings, understand tightly with brill
It mutually presses hole bottom.
1 bottom end of tantalum stick is evenly arranged with spine 1-2, and spine can be pierced into the bottom end got into the cave, and has on spine and connect
The concave point 1-3 of continuous arrangement, slowly spreads on tantalum stick convenient for bone marrow cell along spine and broken bone, improves the treatment of tantalum stick in this way
Success rate.
The tantalum stick further includes the protection pipe 1-4 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 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.
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.
