Abstract
The invention discloses a clavicle intramedullary nail. The clavicle intramedullary nail comprises a strip-shaped cylindrical body. One end of the body is bent to form a hook-shaped structure, and a radial-direction protrusion is arranged at the other end of the body; the body is used for being inserted in through holes of parts to be connected, the hook-shaped structure is used for hooking a hole wall on an opening at one end of one corresponding through hole, and the radial-direction protrusion is used for clamping the other end of each through hole and ensuring that the body can not fall out of the through hole from the hook-shaped structure. The clavicle intramedullary nail has the advantages of being capable of being used for minimally invasive surgery, overcoming the defects that an ordinary intramedullary fixator is poor in stability, resistant to rotation and axially unstable, being capable of being prevented from drifting or falling off and effectively reducing stress concentration and shielding effect, and ensuring that when the nail is taken out, only local anesthesia is needed.
Description
Technical field
The present invention relates to a kind of skeletal fixation apparatus, especially a kind of clavicular intramedullary pin and using method thereof.
Background technology
Clavicle is the serpentine frame between presternum and acromion, is the unique bony framework connected between upper limb and trunk.Clavicle is positioned at subcutaneous, shows shallowly, while being subject to External Force Acting, easily fractures, and the clavicular fracture incidence rate accounts for 5%～10% of whole body fracture, and mostly occurs child and person between twenty and fifty.Clavicular fracture often occurs in middle clavicle; mostly be cross-section or oblique fracture; the inboard broken ends of fractured bone is because being subject to the sternocleidomastoid tractive retrodisplacement that often makes progress; outboard end is subject to inside, the lower displacement of the action of gravity of upper limb; form angulation, dislocation shortening deformity that convex surface makes progress; simple manual reduction is difficult to reach good the resetting of fracture; and the outer fixing good para-position that also can not maintain fracture; only can reach and remove the excessive abnormal movement of bone stump; maintain fracture end in certain lopsided site heals, obvious deformity can be left in part.
For avoiding the generation of lopsided situation, more selection at present is to perform the operation to adopt steel plate or intramedullary needle to fix.Adopting steel plate to fix needs larger otch make the impact of scar after the operation hypertrophy attractive in appearance, and need to peel off the larger area periosteum makes the bone does not connect rate high, steel plate also exists stress concentration easily to cause fixing unsuccessfully to reach stress shielding to cause taking out after inside-fixture the easily defect of refracture, adopts in addition the fixing infection rate of steel plate also higher.Although adopt intramedullary needle to fix, make surgical wound less, intramedullary needle stability maintenance deficiency, be prone to fracture redisplacement, and have the phenomenon of inner matter drift, the withdraw of the needle and broken needle, affects the clavicle healing, when serious, can cause intramedullary needle to move in lung.
