Technical field
The present invention relates to a kind of surgical instruments.
Background technology
The femoral joint of human body is very important component, in the case that lesion, such as joint failure occur for hip joint, needs It takes out the tissue of necrosis and then some artificial materials is filled into femoral joint.The packing material used at present is mostly porous tantalum material Material.During operation, first electricity consumption is drilled on femoral joint and drills, and then takes out joint tissue downright bad in hole, then tantalum stick is inserted hole It is interior, finally with health broken bone tissue blind and sew up a wound.
But during implantation, tantalum stick needs to bear larger power, some tantalum sticks will be twisted off or last It is knocked off when filling broken bone.
Invention content
The object of the present invention is to provide a kind of tantalum bar device, protection tantalum stick will not crush during operation.
To achieve these goals, using following technical scheme：
A kind of tantalum bar device, including tantalum stick, it is characterised in that：The tantalum bar device further includes one for wrapping up the protection of tantalum stick Pipe has equally distributed hole in protection pipe.
The tantalum stick is made of porous tantalum.
Described hole is circle.
Described hole is ellipse.
The protection pipe is made of titanium alloy.
The hole of the protection pipe periphery has 6 on a horizontal plane.
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.

Specific embodiment
The present invention is described further in the following with reference to the drawings and specific embodiments.
As shown in figure 1 to figure 13, a kind of tantalum bar device, including tantalum stick 1-1, the tantalum bar device further includes one for wrapping The protection pipe 1-2 of tantalum stick is wrapped up in, there is equally distributed hole in protection pipe.In this embodiment, tantalum stick is made of porous tantalum. Hole is round and ellipse.The hole of protection pipe periphery has 6 on a horizontal plane.Protection pipe is made of titanium alloy.
It sets hole that can reduce the metal material needed for protection pipe in protection pipe, while protection pipe will not be reduced Intensity, the presence of hole are also beneficial to the regrowth of inside bone tissue.
Protection pipe also protects tantalum stick not buried in embedment by broken bone and breaks into pieces in real time, effectively ensures medical effect.
The tantalum bar device is further included carries out clean cleaning device to the inner tube of protection pipe, and wherein cleaning device includes Pedestal 2 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 gone out Hole into hole and portals corresponding with two openings of protection pipe tube body, saddle 4 is provided on the side wall into below hole, 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, is being portalled Lift plate 8 and dustbin 7 are provided on the side wall of side；
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 protection pipe is placed into the groove on cleaning device pedestal so that two opening difference of protection pipe Connect on base side wall into hole and outlet, then cleaning band out of cleaning band storing apparatus pulled out, is placed on saddle, Microcontroller control linear motor pressure telescopic rod, the extruding of the lowermost gravitation ball fall into mouth, fall into mouth deformation and support big, such gravity The decline of ball, the T connector on cleaning band are squeezed into the T-slot of gravitation ball, and then compressed air sprays compressed air into hole, Push gravitation ball drive cleaning band overcome the pulling force of wind spring in clean bag storing apparatus and along protection pipe pipe body movement, although protecting May there are gap or hole on pillar, but since compressed air flow velocity is bigger, as well as the diameter and tube body of gravitation ball Directly match, therefore gravitation ball also can be than more smoothly advancing in tube body, microcontroller control rocking bar keeps horizontal, clearly 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, and microcontroller control compression is empty Gas stops, and due to the effect of gravity, gravitation ball can move downward, and after it have passed through lift plate, fall into dustbin.On rocking bar The slightly smaller square hole of resistivity knot can block resistance knot, and then, microcontroller control rocking bar is downward, and gravitation ball is promoted, due to lifting Piece is set diagonally downward, when gravitation ball moves upwards, is blocked by lift plate, but at this point, lift plate can upward sliding, When rocking bar moves to bottom, lift plate moves to topmost, and so repeatedly, cleaning band can side-to-side movement, so left and right Movement will clean tubular body using the villus on cleaning band, can be clean after being repeated 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's maintenance.
