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 stick equipment, including tantalum stick 1-1, the equipment includes accommodating tantalum stickProtection pipe 1-2, protection pipe is both ends open, the hollow pipe in middle part, and there are one can rotate for setting on the tube wall of protection pipeWheel 1-3, ripple protrusion is provided on wheel, for the axle position of wheel on tube wall, the rotary shaft of wheel is parallel with the central shaft of protection pipe,Arc the first reed 1-4 is fixed on wheel, the second reed 1-5, the first reed are further fixed on the tube wall of the first reed coveringUpper setting is fluted, and in nature, the second reed bounces outward resists the second reed, is additionally provided on the outer wall of tantalum stickWave groove, the wave groove on the tantalum stick are matched with the ripple protrusion on wheel.
Also there is the groove 1-6 being bent to protection pipe inside wherein on the tube wall of the head end of protection pipe, groove is by tube wallIt is formed by bending.The groove is symmetrically arranged on the tube wall of both sides.Wherein the distance of remaining normal tube wall of groove distance is 3 millisRice.
During operation, tantalum stick is fitted into protection pipe first, the second reed is then allowed to be fitted on tube wall, then by protection pipeIt fills in drilling, rotates tantalum stick, tantalum stick band driving wheel rotates, and the first reed is made far from tube wall, the second reed by own resilientWith also far from tube wall, resisting the groove above the first reed, such second reed by the first reed tightly be against drill hole inner wallOn, protection pipe is firmly fixed in drilling.
After tantalum stick is put into, need to fill in broken bone in the top of protection pipe, the presence of groove allows the broken bone in part to fill in, in this wayThe stability of protection pipe can be further increased, prevents the dislocation of protection pipe.
The bone surgery tantalum stick equipment is further included carries out clean cleaning device to the inner tube of protection pipe, wherein cleaningDevice 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 intoHole and portal, into hole and portal corresponding with two openings of protection pipe tube body, saddle is provided on the side wall into below hole4, 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 bandFirst 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 chamber1, the diameter of gravitation ball is suitable with the diameter of protection pipe tube body, but to subtract inside the tube wall distance of part wheel orThe distance of both groove part maximum, that is the diameter of gravitation ball should facilitate to be passed in and out in protection pipe, on gravitation ballThe T-slot for running through sphere is provided with, T connector is matched with T-slot, and the vertical slots of T-slot are stuck on banking stop, in accommodating chamberRear portion is provided with slice 3-2, and there are two linear motor, the telescopic rod of two linear motors is used respectively for the top setting of crush-cutting deviceIn to the pushing of gravitation ball and the lifting of control slice；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 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 pedestalSliding 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 pipeConnect 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 gravityThe 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 protectingThere are larger gap or hole on pillar, but since compressed air flow velocity is bigger, as well as the diameter and pipe of gravitation ballThe inner space of body is suitable, therefore gravitation ball also can be than more smoothly advancing in tube body, and microcontroller control rocking bar keeps waterFlat, 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 controlCompressed 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.It wavesThe slightly smaller square hole of resistivity knot on bar can block resistance knot, and then, microcontroller control rocking bar is downward, and gravitation ball is promoted, byIt sets in lift plate, when gravitation ball moves upwards, is blocked by lift plate diagonally downward, but at this point, lift plate can be toUpper slip, when rocking bar moves to bottom, lift plate moves to topmost, so repeatedly, cleaning band meeting side-to-side movement, and soSide-to-side movement tubular body will be cleaned using the villus on cleaning band, can be cleaned after being repeated several times dryOnly.
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 timeIn shape slot, lift plate rises to highest point, and entire cleaning band is tightened up, and microcontroller control linear motor output rod declines, pressureAnother gravitation ball, second T connector of cleaning band are snapped into the T-slot of gravitation ball, then, microcontroller control straight-line electricMachine, 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 bandLower 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 upwardsState avoids resistance knot, and if desired tube body, is just placed in the groove of cleaning device, then microcontroller by automated cleaning tube body againOpening 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 waterProsposition such as puts at next resistance knot to be blocked, and then step described above is cleaned repeatedly.Such cleaning to tube bodyIt can do and automatically complete, improve clean efficiency, reduce the time of medical staff.
