Abstract
An ulnar flexible bone crosslocking intramedullary nail of the utility model relates to a fracture fixation implant of human body ulnar flexible bones, and belongs to the medical appliance of bone operations. The structure of the ulnar flexible bone crosslocking intramedullary nail is provided with an intramedullary nail whose far end is equipped with a fixing screw hole and a positioning platform, and a positioning slot is equipped in the intramedullary nail equipment screw. The near end of the intramedullary nail is equipped with the intramedullary nail equipment screw and a near end fixing screw hole, and the bent degree of the nail bar of the intramedullary nail is 1 DEG-1 DEG 30'.
Description
Technical field
What this utility model chi scratched that the bone interlocking intramedullary nail relates to is that a kind of human body chi is scratched bone fracture fixation implant, belongs to the bone surgery medical apparatus and instruments.
Background technology
At present, the human body chi is scratched the bone fractures and is adopted steel plate to fix, the wound face length, and knitting is slow, and is too movable or cause the steel plate fracture easily when bearing a heavy burden in bearing behind the corrective surgery, thereby carries out second operation, causes suffering and injures to the patient.
Summary of the invention
The purpose of this utility model is to provide a kind of chi to scratch the bone interlocking intramedullary nail at above-mentioned weak point, the interlocking intramedullary nail principle is applied to chi scratches the bone fractures, adopt the solid chi to scratch the bone interlocking intramedullary nail, can directly implant chi scratches in the medullary cavity, can prevent the rotation and the shortening of fracture effectively, can carry out the exercise of early stage function of joint and muscle rehabilitation training, especially closure and thread a needle and do not expose fracture site, do not destroy fracture surrounding soft tissue and periosteum blood fortune, speed of fracture union is accelerated.
Chi is scratched the bone interlocking intramedullary nail and taked following scheme to realize: chi is scratched the bone interlocking intramedullary nail and is had intramedullary pin, intra medullary nail far-end is provided with the far-end fixing screw hole, and be provided with locating platform, be provided with intramedullary pin at the intramedullary pin near-end screw, near-end fixing screw hole are installed, install in the screw at intramedullary pin and be provided with locating slot.
When chi is scratched the operation of bone interlocking intramedullary nail; chi is scratched the bone interlocking intramedullary nail scratches proximal bone from chi and packs in the pulp cavity; far-end is packed into fixing in the far-end fixing screw hole with os integumentale screw; near-end is packed into fixing in the near-end fixing screw hole with os integumentale screw; after intramedullary pin fixes; install in the screw with the block intramedullary pin of packing into, screwed hole is installed in protection, so that after the union of fracture intramedullary pin is taken out.
It is reasonable in design that chi is scratched the bone interlocking intramedullary nail, simple in structure, easy to use, scratch the bone interlocking intramedullary nail owing to adopt the solid chi, can directly implant chi during operation scratches in the medullary cavity, intensity and good toughness, too movable or phenomenon of rupture can not occur when bearing a heavy burden in patient bearing, can prevent the rotation and the shortening of fracture effectively, can carry out early stage function of joint exercise and muscle rehabilitation training, especially closure is threaded a needle and is not exposed fracture site, do not destroy fracture surrounding soft tissue and periosteum blood fortune, speed of fracture union is accelerated, alleviate the corrective surgery misery, be convenient to get well early.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is that chi is scratched bone interlocking intramedullary nail front view.
Fig. 2 is that chi is scratched bone interlocking intramedullary nail vertical view.
The specific embodiment
With reference to accompanying drawing 1,2, chi is scratched the bone interlocking intramedullary nail and is had intramedullary pin 1, intramedullary pin 1 far-end is provided with far-end fixing screw hole 3, and be provided with locating platform 7, operating theater instruments location when boring fixing screw hole on the osteoderm when being used to perform the operation, intramedullary pin can not take place axially, radially rotate, and is convenient to aim at intra medullary nail far-end fixing screw hole boring location, can make things convenient for accurately pack into os integumentale screw and positioning and fixing behind the positional punch.Be provided with intramedullary pin mounting screw hole 5, near-end fixing screw hole 4 at the intramedullary pin near-end, install in the screw at intramedullary pin and be provided with locating slot 6, be used for the device block.Intramedullary pin nail bar 2 cambers are 1 °～1 ° 30 ', scratch the bone physiologic radian with the human body chi and conform to.
Claims (3)
1, a kind of chi is scratched the bone interlocking intramedullary nail, it is characterized in that structure has intramedullary pin, and intra medullary nail far-end is provided with fixing screw hole, and is provided with locating platform, is provided with intramedullary pin at the intramedullary pin near-end screw, near-end fixing screw hole are installed.
2, chi according to claim 1 is scratched the bone interlocking intramedullary nail, it is characterized in that being provided with locating slot in intramedullary pin installation screw.
