Abstract
The utility model discloses a fracture fixing apparatus, which comprises a bone plate, bone screws and cylindrical connecting sleeves. The bone plate is provided with internal-thread through holes, the bone screws are flat fillister screws, the outer circumference surfaces of heads of the flat fillister screws are provided with external threads, the inner surfaces of the cylindrical connecting sleeves are provided with internal threads which are used for being matched with the external threads of the heads of the flat fillister screws, and the outer surfaces of the cylindrical connecting sleeves are provided with external threads which are used for being matched with the internal-thread through holes on the bone plate, and the bone plate, the bone screws and the connecting sleeves are in threaded connection. During use of the fracture fixing apparatus, the bone screws are assembled before the bone plate, and accordingly the fracture fixing apparatus is simple and flexible in operation, easy to be adjusted, stable and firm in connection and beneficial to recovery of fracture patients as early as possible. In addition, the whole fixing process can be completed by one person by the aid of the fracture fixing apparatus.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, relates to the fracture fixation device that a kind of orthopaedics is used.
Background technology
Fracture is meant a kind of disease that causes sclerotin partially or completely to rupture owing to reasons such as wound or pathology.Need treatment in time after fracturing, make the injured limb maximum possible, recover its function to greatest extent.The therapeutic modality that the most often adopts is to implement bone surgery, and the fracture site that will take place to be shifted after will fracturing earlier recovers normal again or near original normal position, passes through the surgical incision affected part then; Stick synthetism steel plate (which is provided with a plurality of through holes) at fracture site; The hand steered positive synthetism steel plate of one human, another human drill bit through hole on the synthetism steel plate is screwed into steel nail in institute's bore bone hole to the bone internal drilling afterwards; Carry out internal fixation, the fracture site after preventing to reset is shifted again.Blade plate is gone up the defective that the fixed form of steel nail exists again and is in this elder generation: when fracture took place some privileged sites of human body, blade plate was gone up steel nail again and can relatively be required great effort in the elder generation, is awkward.
Summary of the invention
This utility model technical problem to be solved is: a kind of fracture fixation device is provided to above-mentioned defective, this fixture in use, the synthetism nail is gone up blade plate again elder generation in, and is simple to operate flexible, easy adjusting.
For solving the problems of the technologies described above, the technical scheme of this utility model is: fracture fixation device comprises: blade plate, and said blade plate is provided with internal thread through hole; The synthetism nail, said synthetism nail is fillister head screw, the outer peripheral face of said fillister head screw ailhead is provided with external screw thread; Adapter sleeve; Said adapter sleeve is cylindric; The inner surface of said cylindric adapter sleeve is provided with and is used for and the suitable female thread of the external screw thread of said fillister head screw ailhead, the outer surface of said cylindric adapter sleeve be provided be used for said blade plate on the suitable external screw thread of internal thread through hole; Be threaded between said blade plate, synthetism nail and the adapter sleeve.
As optimized technical scheme, said fillister head screw is hexagon socket cap head screw or cross recess fillister head screw or flat recess fillister head screw.
As optimized technical scheme, said blade plate, synthetism nail and adapter sleeve are stainless steel component.
Owing to adopted technique scheme, the beneficial effect of this utility model is: at the fracture fixation device that uses this utility model fracture site fixedly the time, is holed in the proper site in the affected part of fracturing with drill bit earlier; Afterwards the synthetism nail is screwed into institute's bore bone hole, lets ailhead be exposed, then blade plate is attached on the bone; The internal thread through hole of blade plate end is enclosed within around the ailhead of synthetism nail, is used for and the suitable female thread of the external screw thread of ailhead because the inner surface of adapter sleeve is provided with, the outer surface of adapter sleeve be provided be used for blade plate on the suitable external screw thread of internal thread through hole; At this moment; Can easily adapter sleeve be connected with synthetism oncomelania stricture of vagina with blade plate, thereby blade plate is securely fixed in the fracture affected part, whole fixation procedure one people just can accomplish; Simple to operate flexible; Be prone to regulate, and this connecting device is firmly stable, helps the fracture patient early recovery.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Accompanying drawing is the structure cross-sectional schematic of this utility model embodiment;
Among the figure: the 1-blade plate; The 2-adapter sleeve; 3-synthetism nail.
The specific embodiment
Shown in accompanying drawing, fracture fixation device comprises: blade plate 1, and said blade plate 1 is provided with internal thread through hole; Synthetism nail 3, said synthetism nail 3 is a fillister head screw, the outer peripheral face of said fillister head screw ailhead is provided with external screw thread; Adapter sleeve 2; Said adapter sleeve is cylindric; The inner surface of said cylindric adapter sleeve is provided with and is used for and the suitable female thread of the external screw thread of said fillister head screw ailhead, the outer surface of said cylindric adapter sleeve be provided be used for said blade plate 1 on the suitable external screw thread of internal thread through hole; Be threaded between said blade plate 1, synthetism nail 3 and the adapter sleeve 2.
In the present embodiment, said fillister head screw is a hexagon socket cap head screw, can certainly adopt the cross recess fillister head screw, perhaps the flat recess fillister head screw.
In the present embodiment, said blade plate 1, synthetism nail 3 and adapter sleeve 2 are stainless steel component.Also can adopt the titanium alloy member.
Operation principle: at the fracture fixation device that uses this utility model fracture site fixedly the time, is holed in the proper site in fracture affected part with drill bit earlier, afterwards synthetism is followed closely 3 and be screwed into institute's bore bone hole; Ailhead is exposed, and then blade plate 1 is attached on the bone, make that the internal thread through hole of blade plate 1 end is enclosed within that synthetism nail 3 exposes ailhead around; Screw in adapter sleeve 2 again, it is threaded with blade plate 1 and synthetism nail 3, thereby an end of blade plate 1 is fixed; Adopt afterwards in the same way, on bone, bore another hole, the synthetism of screwing on nail 3; Through adapter sleeve 2 other end and the synthetism nail 3 of blade plate 1 are fixed, whole fixation procedure one people just can accomplish, and is simple to operate flexible; Be prone to regulate, and this kind connecting device is firmly stable, helps the fracture patient early recovery.
The above is giving an example of this utility model preferred forms, and the part of wherein not addressing in detail is those of ordinary skills' common practise.The protection domain of this utility model is as the criterion with the content of claim, and any teachings and equivalent transformation of carrying out based on this utility model is also within the protection domain of this utility model.
