Abstract
The utility model provides inner fixed frame locking and pressurizing holes. The inner fixed frame locking and pressurizing holes are characterized in that each inner fixed frame locking and pressurizing hole is formed by a locking hole and a pressurizing hole, wherein a portion of the locking hole and a portion of the pressurizing hole are overlapped, the locking hole is a cone-shaped threaded through hole, and the pressurizing hole is an unthreaded through hole provided with an arc-shaped pressurizing slope. The locking and pressurizing holes are evenly distributed in an inner fixed frame, and a clearance which is 0.3 millimeter to 0.5 millimeter is formed between a skeleton and the inner fixed frame.
Description
Technical field
The present invention relates to a kind of locking compress hole in the inner fixed stand system of orthopedics.
Background technology
For a long time, the orthopedic most of blade plate technology that adopts of fracture and bone, the contacting and fixedly be the frictional force of leaning on each other of blade plate and bone, so the hole of its blade plate only possesses the function of pressurization and tension and bone close contact.And inner fixed stand is different from blade plate, there is certain space between its fixed mount main body and the skeleton, this space is in order not destroy periosteum and to keep the blood of fracture end to transport, accelerating union of bone fracture and raising healing of fracture, so necessary locking compress between inner fixed stand main body and the screw, and very firm, at present there are no the report that closes inner fixed stand locking compress hole.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides and a kind of not only can the cooperation with the lock screw nail realized firm locking, but also can cooperate realization that fracture end is pressurizeed with the pressure bone setting nail, guarantee simultaneously the inner fixed stand locking compress hole of the noncontact fixed frame between inner fixed stand and the bone.
The technical solution used in the present invention is, a kind of inner fixed stand locking compress hole, it is characterized in that, bore portion is overlapping forms by lock hole and pressurization in this hole, lock hole is the tapered thread through hole, the pressurization hole for arc add pressure slope without tapped through hole, described locking compress hole is uniformly distributed in skeleton and exists on the inner fixed stand in 0.3mm-0.5mm gap.
By locking compress hole hole slot, lock screw nail and pressure bone setting nail end enter skeleton, and locking compress hole, lock screw nail, pressure bone setting nail, inner fixed stand and skeleton consist of the fixing frame system of noncontact.
When operation needed, inner fixed stand was positioned over the bone surface after the reduction of the fracture, at first utilized the lock screw nail to be fixed in a side by the present invention, and after inner fixed stand was basicly stable, the opposite side of fracture end was fixing by the pressurization of fracture with compressive bone nail; Pressure bone setting is followed closely each inner fixed stand system usually only with one, and all other selects the lock screw nail to be fixed; The present invention has realized that the noncontact between bone and the inner fixed stand fixes, and has guaranteed the blood fortune of fracture end, accelerating union of bone fracture and improve healing of fracture.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of one embodiment of the invention.
Fig. 3 is the plan structure sketch map of Fig. 2.
Among the figure: 1, pressure bone setting nail, 2, inner fixed stand locking compress hole, 3, inner fixed stand, 4, the lock screw nail, 5, skeleton, 6, the gap of inner fixed stand and skeleton.
The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
In use, by the locking compress hole, lock screw nail end utilizes lock screw that inner fixed stand is fixed on the fracture site, 1 pair of fracture end of pressure bone setting nail pressurizes, and inner fixed stand makes and self is suspended on bone surface by the distance of 0.3mm-0.5mm between arcuate groove maintenance and the skeleton, consist of the noncontact fixed frame, make periosteum neither peel off and can not be oppressed necrosis, thereby keep the good blood fortune of fracture end, promote union of fracture; Stress and deformation motion by arcuate groove produces stress transfer to fracture end, makes the skeleton after the fracture fixation still can be by suitable stress stimulation and healing acceleration and complication shorten healing time, reaches and fixes biology.
Claims (2)
