The special bone grafting instrument can be drilled in a plurality of directions to fully dredge a harden belt, so that a great quantity of bone grains can be safety, conveniently, fast and correctly sent to a bone grafting area and then are compressed tightly; and the special bone grafting instrument has the advantages of being reasonable in structural design, being simple and convenient and reliable to operate, saving the time, reducing the bleeding and facilitating the osteogenesis.
Description
Technical field
This utility model belongs to technical field of medical instruments, and what relate generally to is a kind of femur head necrosis bone grafting special equipment.
Background technology
At present, the clinical conventional means that ischemic necrosis of femoral head is protected the hip treatment comprises medulla decompression and the head and neck impaction bone grafting of windowing.The ANFH patient is doing impaction bone grafting when operation in the prior art, after head and neck is windowed, removed sequestrum, does not have special equipment to push fresh bone of getting ready and allograph bone urgent.Because when dredging femur head necrosis district hardenability band, traditional electric drill and Kirschner wire can't fully be dredged hardenability band to all directions because of the constraint of its structure and operation technique district surrounding tissue.Because darker because of the position during medulla decompression bone grafting, osseous granules is difficult for sending into focal zone and suppresses closely.The drawback of bringing thus is to influence bone grafting effect and new bone growth, and new bone growth is difficult to through hardenability band, and then influences the operative effect of femur head necrosis.We invent the femur head necrosis bone grafting apparatus in the case; Can a plurality of direction borings fully dredge hardenability band; Quick and precisely a large amount of skeletal grains are sent into bone graft area and sclerotin is suppressed closely increase bone grafting effect and promotion new bone growth, and then the operative effect of raising femur head necrosis.
The utility model content
The purpose of this utility model promptly produces thus; A kind of femur head necrosis bone grafting special equipment is proposed; This apparatus can a plurality of direction borings fully be dredged hardenability band; Quick and precisely a large amount of skeletal grains are sent into bone graft area and sclerotin are suppressed closely, have reasonable in design, easy and simple to handle reliable, save time, reduce hemorrhage, as to be beneficial to skeletonization characteristics.
This utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of femur head necrosis bone grafting special equipment comprises the arcuate guide device, arc bone grafting rod, and funneling bone grafting device, arcuate guide device are hollow structure, the one of which end is the arc elbow; Arc bone grafting rod is a solid construction, and the one of which end is the arc elbow; Funneling bone grafting device is made up of guide thimble, bone grafting funnel, sleeve pipe handle, bone grafting device inner core and inner core handle; Guide thimble is a hollow structure; Be connected with the bone grafting funnel that is communicated with it on it; One end is connected with the sleeve pipe handle, and bone grafting device inner core inserts in the guide thimble, and the one of which end is connected with the inner core handle.
The angle of above-mentioned arcuate guide device arc elbow is 40 degree or 55 degree or 70 degree.
The angle of above-mentioned arc bone grafting rod arc elbow is 40 degree or 55 degree or 70 degree.
This utility model is reasonable in design, and the arcuate guide device of design can be adjusted the direction of electric drill Kirschner wire through hardenability band, fully dredges hardenability band to all directions boring, helps skeletonization; Arc bone grafting rod can be suppressed osseous granules closely, and the arcuate guide device cooperates arc bone grafting rod, and it has solved mediation hardenability band and impaction bone grafting problem closely.Funneling bone grafting device not only can be safely, convenient, intactly osseous granules is implanted corresponding focus, and during bone grafting in the medullary cavity air from the groove of pipe portion, flow out, can sclerotin be suppressed closely; Can not produce clogging, thereby improve the operation quality, improve surgical effect; Practice thrift operating time, reduce hemorrhagely, can prevent that the femoral head at weight loading region secondary from subsiding; Help the recovery of hip joint function, thereby improve the curative effect of treatment femur head necrosis.Whole design is easy rationally.

The specific embodiment
In conjunction with accompanying drawing, the embodiment that provides this utility model is following:
The described femur head necrosis bone grafting of present embodiment special equipment comprises the arcuate guide device, arc bone grafting rod, funneling bone grafting device three parts.Shown in Fig. 1-3: arcuate guide device 1 is a hollow structure, and the one of which end is the arc elbow, and the angle of arc elbow has 40 degree, 55 degree and 70 degree.During use, can adjust the direction of electric drill Kirschner wire, fully dredge hardenability band, help skeletonization to all directions boring through hardenability band through the arcuate guide device of different angles.
Arc bone grafting rod 2 is a solid construction, and the one of which end is the arc elbow, and the angle of arc elbow has 40 degree, 55 degree and 70 degree.During use, the arc bone grafting rod through different angles can go deep into deep, femur head necrosis district, can osseous granules be suppressed closely, and the bone piece supports and more meets biomechanical property, helps skeletonization.Can prevent that the femoral head at weight loading region secondary from subsiding, help the recovery of hip joint function, effectively improve the curative effect of treatment femur head necrosis.The arcuate guide device is used arc bone grafting rod and has solved mediation hardenability band and impaction bone grafting problem closely.
Funneling bone grafting device is made up of guide thimble 3, bone grafting funnel 4, sleeve pipe handle 5, bone grafting device inner core 6 and inner core handle 7, and guide thimble 3 is a hollow structure, is connected with bone grafting funnel 4, one ends that are communicated with it on it and is connected with sleeve pipe handle 5.Bone grafting device inner core 6 inserts in the guide thimble 3, and the one of which end is connected with inner core handle 7, and the groove of pipe portion is positioned on guide thimble 3 tube walls.During use; The guide thimble 3 of funneling bone grafting device is inserted the Close Tunnel of medulla decompression; Skeletal grain is put into the inlet of bone grafting funnel 4, a hand-held sleeve pipe handle 5, another hand-held inner core handle 7; Bone grafting device inner core 6 is inserted in the guide thimbles 3, skeletal grain is sent into bone graft area and hit tight through bone grafting device inner core 6.This apparatus has overcome in the past block-by-block to be implanted skeletal grain and can't suppress shortcoming closely, can quick and precisely a large amount of skeletal grains be sent into bone graft area through funneling bone grafting device, can sclerotin be suppressed closely; And during bone grafting in the medullary cavity air from the groove of pipe portion, flow out, can sclerotin be suppressed closely, can not produce clogging; The bone piece supports and more meets biomechanical property; Help skeletonization, and practice thrift operating time, reduce hemorrhage.
