Abstract
The invention provides a locking hole of an inner fixing frame, which is characterized in that the hole is a tapered thread through hole and is uniformly distributed on the inner fixing frame which has a distance of 0.3-0.5 mm from a bone.
Description
Technical field
The present invention relates to a kind of lock 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 of blade plate and bone by the frictional force between mutual, so the hole of its blade plate only possesses the function that pressurization and tension and bone closely contact.And inner fixed stand is different with blade plate; There is certain gap between its fixed mount main body and the skeleton; This space is to transport with the blood of maintenance fracture end in order not destroy periosteum, accelerating union of bone fracture and raising union of fracture quality, so must lock between inner fixed stand main body and the screw; And very firm, the present report of not seeing relevant inner fixed stand lock hole.
Summary of the invention
For overcoming the deficiency of prior art, the present invention provided a kind of not only can the cooperation with the lock screw nail to realize firmly locking, but also can realize the inner fixed stand lock hole of the noncontact fixed frame between inner fixed stand and the bone.
The technical scheme that the present invention adopts does, a kind of inner fixed stand lock hole is characterized in that this hole is the tapered thread through hole, and is uniformly distributed in skeleton and exists on the inner fixed stand in 0.3mm-0.5mm gap.
Through the lock hole hole slot, the terminal skeleton that gets into of lock screw nail, lock hole, lock screw nail, inner fixed stand and skeleton constitute the fixed 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 fix in a side through the present invention, and after inner fixed stand was basicly stable, the opposite side of fracture end was fixing through fracture lock screw nail; The present invention had both realized that the noncontact between bone and the inner fixed stand fixed, and had guaranteed the blood fortune of fracture end, accelerating union of bone fracture with improve the union of fracture quality, cooperate with the lock screw nail again to make the inner fixed stand system form independently framework.
Description of drawings
Fig. 1 is a 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, pressurization synthetism nail, 2, the inner fixed stand lock hole, 3, inner fixed stand, 4, the lock screw nail, 5, skeleton, 6, the gap of inner fixed stand and skeleton.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Embodiment 1, a kind of inner fixed stand lock hole, and with reference to Fig. 1, Fig. 2, shown in Figure 3, this hole is the tapered thread through hole, and is uniformly distributed in skeleton and exists on the inner fixed stand in 0.3mm-0.5mm gap 6; Through the lock hole hole slot, the lock screw nail 4 terminal skeletons 5 that get into, lock hole 2, lock screw nail 4, inner fixed stand 3 and skeleton 5 constitute the fixed frame system of noncontact.
In use, through lock hole, lock screw nail end utilizes lock screw that inner fixed stand is fixed on the fracture site; Under the cooperation of pressurization synthetism nail 1, inner fixed stand makes and self is suspended on bone surface through the distance of 0.3mm-0.5mm between arcuate groove maintenance and the skeleton; Constitute 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 through arcuate groove produces stress transfer to fracture end, make skeleton after the fracture fixation still can be through suitable stress stimulation healing acceleration and minimizing complication, the shortening healing time reaches and fixes biology.
Claims (2)
1. an inner fixed stand lock hole is characterized in that, this hole is the tapered thread through hole, and is uniformly distributed in skeleton and exists on the inner fixed stand in 0.3mm-0.5mm gap.
2. a kind of inner fixed stand lock hole according to claim 1 is characterized in that, through the lock hole hole slot, and the terminal skeleton that gets into of lock screw nail, lock hole, lock screw nail, inner fixed stand and skeleton constitute the fixed frame system of noncontact.
