Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to the inner fixing device of treatment inboard, tibia lower end and ankle fracture, particularly treats the nail-plate device of inboard, tibia lower end and ankle fracture, and concrete is the hook-shaped nail-plate of the inboard T type in a kind of tibia lower end.
Background technology:
In the prior art, for tibia lower end medial part and interior ankle treatment of fractures, multiple therapy methods is arranged clinically, as many employings SANYE plate screw internal fixation, dissection armor plate screw internal fixation, the Kirschner wire internal fixation adds external plaster fixation, simple cancellous bone screw fixedly adds multiple therapy methods such as external plaster fixation, manual reduction medial and lateral malleolus clamping plate or external plaster fixation.Because the fracture at this position usually can feed through to the ankle joint face, so the clinical treatment aspect requires very strictness, intra-articular fracture resets to fix and must reach anatomical reduction or approximate anatomical reduction.In addition, ankle joint belongs to the heavy burden joint, be again a joint that mobility is bigger simultaneously, the particularly interior ankle of fracture site after resetting, in order to keep the stable and balance of ankle joint, ankle adheres to the tractive that ligament is the huge tractive strength of deltoid ligament in usually needing to stand, if internal fixation is not firm, tend to make interior ankle fracture redisplacement or malunion after resetting, joint ligament relaxation, ankle joint instability, traumatic arthritis, the appearance of sequela such as ankylosis causes the patient suffering to increase and causes the operative treatment failure.A good results of surgical normally by superb clinical technology and consummate operation skill, is added and is had that the good internal fixation apparatus that meets human body normal physiological structure finishes jointly.Above-mentioned inside and outside fixing means and fixation device exist mostly that operation wound is big, immobile phase is to deficiencies such as shakinesses, cause the inboard and interior ankle fractures rear stability in tibia lower end not good enough, cause surgical effect not good, complication increases, makes the painful mentally and physically increase of patient.
The utility model content:
The purpose of this utility model is to provide a kind of tibia lower end medial part T type hook-shaped nail-plate inner fixing device, the hook-shaped nail-plate device of the inboard T type in described this tibia lower end is to solve in the prior art in the ankle fractures big, fixing not firm, the stable technical problem such as not good enough of existing operation wound tibia the lower end in.
The hook-shaped nail-plate of the inboard T type in this tibia of the present utility model lower end, walking crosswise strip steel plate and a stringer strip steel plate by one is the T font and fixedlys connected and constitute, described strip steel plate is made of flat board, walk crosswise flat board and be circular-arc, consistent with the inboard surface of bone profile in tibia lower end, described walking crosswise is arranged to rare two circular holes in the flat board, the dull and stereotyped major axis of described stringer side is seen and is the inflection arc, be arranged to a rare circular hole in the described stringer flat board, a chute hole and an internal malleolus hole, described chute hole is set to the stringer bathtub construction, the dull and stereotyped end of described stringer is provided with an internal malleolus hole, the plane and the internal malleolus center longitudinal axis in described internal malleolus hole are perpendicular, be provided with one piece of locking cancellous bone screw in the described internal malleolus hole, described locking cancellous bone screw tail end is provided with external screw thread, described internal malleolus hole inner face is provided with the female thread groove, match with the rear external screw thread of locking cancellous bone screw, described locking cancellous bone screw y direction is consistent or overlapping with the internal malleolus center longitudinal axis, be provided with screw in described circular hole and the chute hole, the tip of described screw and locking cancellous bone screw all is positioned at dull and stereotyped inboard, the axial cross section in circular hole and internal malleolus hole is all V-shaped, and the tail end circumference of locking cancellous bone screw and screw all is coniform.
Further, be provided with interior hex slot in the driving end face of described locking cancellous bone screw and screw.
Further, the transverse diameter of described chute hole and circle hole groove cooperates with the rear end diameter of screw.
The fixation principle of laying of the present utility model: the hook-shaped nail-plate of the inboard T type in tibia lower end that reaches the contour structures design of interior ankle according to tibia lower end medial part, when being applied to inboard, tibia lower end and interior ankle fractures, after above-mentioned position fracture operation cuts manual reduction, it is temporary fixed to utilize thin Kirschner wire to do, place the hook-shaped nail-plate of the inboard T type in tibia lower end then, boring, tapping in each hole in order, tighten each screw, finish the internal fixation step.The stringer flat board is provided with the suitable forcing screw of an energy hole and matches with one piece of screw, play the suitably effect of pressurization of fracture end, the place is provided with an internal malleolus hole at the dull and stereotyped hooked ends of stringer, cooperate with the externally threaded one piece of locking cancellous bone screw of rear band, play internal ankle fracture far-end reset fixing suitably pressurization and inner support fixation, especially there is comminuted fracture in this nail-plate device for interior ankle and has under the situation of polylith sclerite application the most suitable.
This utility model is compared with prior art, and its effect is actively with tangible.This utility model is according to the construction profile of inboard, tibia lower end and interior ankle, the hook-shaped nail-plate of the inboard T type in the tibia lower end of design, complete firm with fixing after the capable open reduction of ankle fracture in the tibia lower end, the stringer flat board is provided with a screw hole with pressurization function and matches with one piece of screw, play the effect that suitably to pressurize to the fracture end face, be provided with an internal malleolus screw hole at the dull and stereotyped tail end of stringer, cooperate with the externally threaded one piece of locking cancellous bone screw of rear band, play internal ankle fracture far-end reset fixing suitably pressurization and inner support fixation, especially be fit to use under the situation that the inboard and interior ankle comminuted fracture in tibia lower end has the polylith sclerite.Can make effectively the tibia lower end inboard and in the ankle reduction of the fracture fixing reliable, effectively prevent the loosening and displacement again of fracture site, exempt early stage reparation and functional rehabilitation that external fixation can impel ankle and articular ligament, avoided the generation of plaster-of-Paris disease.
