Description
Technical field
The present invention relates to a kind of medical apparatus and instruments for the treatment of fracture usefulness.
Background technology
The method of treatment fracture for many years, has clamping plate expopexy, surgical incision internal fixation with steel plate, support arm fixation.These methods all do not solve the accurate para-position problem of fracture portions.Up to the present, as long as can make that fracture two broken ends of fractured bone skew is not more than 2/3rds, limbs shorten and be not more than 2 centimetres and just meet national standard.Even so low standard also is difficult to reach.Because para-position is bad, makes the osteanagenesis time lengthening, or leaves permanent spatium interosseum, thereby cause the fracture site malunion, can not recover normal function fully; What have can not cure because of para-position is bad, causes deformity.Adopt the operation second time of also will carrying out of internal fixation with steel plate to remove steel plate, increase patient suffering and financial burden, prolonged healing time.
Summary of the invention
The purpose of this invention is to provide a kind of fracture para-position machine, accomplish the accurate para-position of fracture portions, accelerated bone regeneration and healing time.
Technical scheme is that the leading screw cervical region is set in the axis hole of main support plate, and feed screw nut and assistant support plate are affixed, and guide post one end is fixed on the main support plate, the other end interts in fairlead, and fairlead and assistant support plate connect firmly; The inboard, upward middle part of major and minor supporting plate is semi-circular step, and the arcuate guide cylindrical void is arranged on the semi-circular step, and the edge that external diameter is identical with the step external diameter has the semi-circular angular adjustment dish of local sawtooth to be embedded on the semi-circular step; The guiding pin that the angular adjustment dish is fitted on the semi-circular step is positioned at the arcuate guide cylindrical void, and its lower end rotation set is on the angular adjustment dish; The adjusting gear that is meshed with angular adjustment plate edge sawtooth is positioned at the gear hole of supporting plate, and the adjusting gear main shaft stretches out and is fixedly connected with angle hands wheel on the outer end of supporting plate; The arc slot of angular adjustment dish is equipped with steel nail hook or clamping device with bolt, and both sides, major and minor supporting plate bottom have movable pulley respectively, and main or assistant support plate bottom is equipped with fixed cage.
Using method of the present invention and operation principle are as follows:
At first with fixed cage master of the present invention or assistant support plate are fixed on the operation table, each makes a call to a through hole at the two ends of patient's knochenbruch according to the operational approach of support arm fixation, plugs the screw thread nail; Each makes a call to one and half through holes in the inboard of two through holes again, also sets up the screw thread nail.Then patient's limbs are put in the present invention, fracture far-end limbs are positioned on loose master or the assistant support plate, two screw thread nails on the through hole are enclosed within respectively in the steel nail hook or clamping device of major and minor supporting plate upper angle adjustment disk, fixing tight with screw.Under the perspective of C type arm X-ray machine, first rotational lead screw handwheel drives loose supporting plate through the leading screw nut and vertically moves, and makes knochenbruch length and strong limb bone appearance etc.Owing to the scale that shows the leading screw movable length can be installed, so the may command error in length is in 1 millimeter.If the vertical height para-position is uneven, can suitably adjust the installation site of steel nail hook in angular adjustment dish arc slot.
After, length adjustment neat when the height para-position was good, the rotational angle handwheel drove the angular adjustment dish and carries out angle adjustment through adjusting gear again.Available C arm machine is had an X-rayed from multi-angle, and fluoroscopy images is imported computer, carries out multi-angle contrast, overlapping with strong limb bone image, adjusts at machinery on the basis of angle, and the screw thread nail with in whole two inboard half through holes of hand adjustment is close to it.Angle adjustment can make angular error within 1 degree.Use support arm (on sale on the market) the interior screw thread nail of fastening two inboard half through holes earlier at last, the screw thread nail in fastening again two through holes is finished whole operations.
Compared with the prior art, the present invention has following advantage:
1, bit errors is low
Overcome at present that blindness state, the power of elongating patient's severed limb by many people are drawn longly greatly, power is not enough and drawn short problem.The present invention rotates the method that becomes straight-line displacement with leading screw and elongates patient's severed limb, and error in length can be controlled in 1 millimeter; Adjust angle with the angular adjustment dish, angular error is controlled within 1 degree; Therefore can obtain reliable curative effect.
2, recover the good reliability of normal function fully.
Because para-position is more accurate, therefore structure, the function of severed limb all can be recovered normally fully, thorough curative effect is up to more than 95%, good reliability.
3, operation and healing time all shorten more than 1/3rd.
4, the present invention is a kind of Minimally Invasive Surgery machinery, need not to cut limbs and carries out getting the second time interior steel plate operation, has therefore both alleviated the patient suffering, saves medical expense again.
