Description
Technical field
It is a kind of fracture compression locating device specifically the present invention relates to technical field of medical instruments.
Background technology
People are caused fracture by unexpected injury unavoidably in production, life, have not only brought pole
Big pain, malpractice is also possible to leave lifelong disability, influences normal production and living, or even lose the energy taken care of oneself
Power.It is the target that orthopedist pursues to reach that good reset recovers normal physiological function after fracture, in art.However, human body
Bone it is complex-shaped, the degree being hurt is also different, to accomplish sometimes completely recovery, be not impossible by utensil
's.Then, medical science and technology worker has developed a variety of suitable for the different parts reduction of the fracture and fixed steel plate, achieves good
Good using effect, is that thousands upon thousands fracture patients relieve the pain of injury.Its steel plate needs to be fixed on fracture by forcing screw
At block position, however, in the prior art there is following defect and deficiency in medical worker for screw fixation steel plate.
First, when medical worker of the prior art carries out interior fixed, screw 5 is inserted generally by electric drill, screw 5
Trend can only be experience and exploration according to doctor to position, it occur frequently that sclerite skew, fixed not firm, positioning and directing
Difficult, 5 dozens, sclerite screw is oblique, sclerite drops, so as to cause operation not carry out smoothly.
Secondly, the physiological structure of different fracture sites is different, and different parts need the different trend of screw 5, only with electric drill
Sclerite can not be accurately positioned, can not accurately be oriented to punching by inserting screw 5.Than as seen in Figure 6, fracture of calcaneus, steel plate 4 be placed on
The sustentaculum of talus 62 that 6 are surveyed 61 on the outside of bone, but in calcaneum is (extremely important, to carry the weight of astragalus) it is difficult to be fixed to.Position is low
Fixation is not lived, high to arrive articular surface 63.Similarly, it is also so (see Fig. 7) that olecroanon, which merges the fracture of coronoid process 64,.And at some
In special case, such as near end of thighbone comminuted fracture is fixed, it is necessary to insert intramedullary nail 65 in marrow with reference to steel plate 4, is so also required that
Screw 5 on steel plate 4 will accurately avoid the intramedullary nail 65 in pulp cavity (see Fig. 8 and Fig. 9).
In addition, being typically to select the specification of screw 5 to beat by rule of thumb in the prior art in steel plate 4 during drivescrew 5
Enter, before squeezing into, it is impossible to which the length to screw 5 is measured, the problem of screw 5 is too short or long usually occur, screw 5 is too
It is short to fix, it is oversize to arrive soft tissue.
Furthermore, in current operation technique apparatus, electric drill is all to be beaten from one side of bone to another side (see Figure 10), and ideal is done
Method thinks screw 5 to come out from exit point 66 so that screw 5 moves towards fracture line 68 vertically, but actual deviation of moving towards exports B points
67, meanwhile, electric drill easily opens opposite osteocomma top, to osteocomma without pressurization.
Chinese patent literature CN201520198375.3, the applying date 20150403, patent name is：Intertrochanter fracture of femur
DHS locating guiders, disclose kind of an intertrochanter fracture of femur DHS locating guiders, and it includes locating rod, is connected to positioning rod end
The fixing steel plate in portion and one end are connected in the pilot sleeve that the locating rod other end is connected to fixing steel plate, the locating rod
The central axis copline A of heart axis and fixing steel plate, in 12-15 ° of folder between the central axis and plane A of the pilot sleeve
Angle.
Above-mentioned patent document is intended to solve a kind of to avoid cause pierce guide pin due to anteversion of femoral neck reason
The problem of Shi Rongyi is shifted, main nail are screwed into and are inserted in steel plate after steel plate and fitted completely with femur the displacement fracture (rear point caused
From) problem and steel plate with femur rear laminating front separate the problems such as later stage broken nail rate is big.But, on fixed, energy
Enough it is accurately positioned that sclerite and guiding, screw length are measurable, the technical scheme for the osteocomma that can pressurize is then without corresponding open.
In summary, it is necessary to it is a kind of it is fixed, can be accurately positioned sclerite and guiding, screw length it is measurable,
Can be pressurizeed the fracture compression locating device of osteocomma, and yet there are no report on this fracture compression locating device.
The content of the invention
