Description
Technical field
This utility model relates to technical field of medical instruments, and is particularly a kind of for the outer fixing outer prelum that fixedly lifts of bone.
Background technology
The development of the bone external fixation device history of existing more than 100 year, it has easy and simple to handle, and wound is little, and patient's misery is little, and the advantages such as good effect have obtained since over half a century using more and more widely clinically.Recent two decades comes, and along with the development of materialogy and biomechanics, external fixation device has obtained significant progress, and the performances such as its configuration, volume, weight and connected mode, x-ray permeability meet clinical needs all more.External fixation device can make the patient obtain the most effectively treating with the wound of minimum, have the unrivaled advantage of other method at aspects such as the serious soft tissue contusions for the treatment of fracture merging, has now become the preferred option for the treatment of open fracture.
For most of open fractures, the external fixed support for bone treatment of going in early days can be played fracture end temporary fixed really, and the protection soft tissue is conducive to suffer from the advantages such as nursing of limb.Need operation again because of the dislocation of fracture end or nonunion but still have clinically a lot of patients.And the reason that causes this result is mostly because early stage bone outward fixedly the time to the malreduction of fracture end.Although at present both at home and abroad external fixation device design is totally different, of a great variety, difference only shows on the connected mode of material and shank, and to operation and no significant difference after the resetting and reset of fracture end.Be all hand operation to fracture end reduction in art, the patient is the Traction fracture end with the hands, resetting is connected apparatus after satisfied again, and shortcoming is that the patient can not bestow powerful external force to the fracture end of displacement and effectively resets and keep the stable of fracture end in art.
Summary of the invention
The purpose of this utility model is that the defective for prior art provides a kind of outer prelum that fixedly lifts, it can be used in combination with various bone external fixation devices, makes patient's fracture end can obtain effectively resetting with fixing, reduces bone does not connect, the incidence rate of nonunion alleviates patient's misery.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of outer prelum that fixedly lifts comprises the linking unit that lifts presser unit and be used for being connected bone external fixation device connecting rod; Lifting presser unit is connected by the axle that is rotatably connected with being connected between the unit;
Lifting presser unit comprises and lifts Needle with pressure-increasing means, lifts pressurization axostylus axostyle and annulus; Lifting the pressurization axostylus axostyle is threadedly connected in annulus; Lift Needle with pressure-increasing means and run through and lift the pressurization axostylus axostyle, and with to lift the pressurization axostylus axostyle coaxial, be threadedly connected to lift in the pressurization axostylus axostyle; Lift pressurization axostylus axostyle upper end and be provided with fastening operating portion;
Be connected the unit and comprise the connecting rod fixture and the axle keeper that is rotatably connected; The end of axle of being rotatably connected is rotationally connected the connecting rod fixture, and the other end is fixedly connected with the annulus that lifts presser unit; Be rotatably connected and be fixed by the axle keeper that is rotatably connected between axle and connecting rod fixture.
This utility model is when using, first need to lift pressurization place at sclerite is screwed into and lifts Needle with pressure-increasing means, regulate again and be connected the unit at the upper-lower position of connecting rod, and regulate by the axle rotation in the horizontal direction that is rotatably connected and lift the position of presser unit on horizontal plane, make and lift Needle with pressure-increasing means and be positioned at the centre that lifts presser unit, and be fixed on connecting rod by being connected the unit, utilize the axle keeper that is rotatably connected to be kept fixing, then be screwed into and lift the pressurization axostylus axostyle; Next, due to lift Needle with pressure-increasing means be threadedly connected to lift the pressurization axostylus axostyle in, therefore can be by to lifting the operation that turns of the fastening operating portion of pressuring shaft masthead section, change and lift Needle with pressure-increasing means and impose on the pressure of fracture site or lift power, so that fracture end can axially move up and down along lifting Needle with pressure-increasing means, realize effectively resetting and keeping the stable of fracture end.
As a kind of improvement, lift presser unit and also comprise sealing cap, sealing cap is removably fixed in the top of annulus, sealing cap inside is provided with handle hole, lift the outline projection that the pressurization axostylus axostyle tightens operating portion and be positioned at the handle hole profile, and the diameter of handle hole, lifts the pressurization axostylus axostyle and can not break away from from annulus in the time of can guaranteeing upwards to turn the fastening operating portion of interior hexagonal that lifts pressuring shaft masthead section less than the diameter that lifts the pressurization axostylus axostyle.The sealing cap top can be set to interior hexagonal form, so that installation and removal.Sealing cap can be threaded connection the top that mode is removably fixed in annulus.
Further, in linking of the present utility model unit, the connecting rod fixture comprises 2 pressure pads that are set in parallel in the connecting rod both sides, is respectively equipped with the draw-in groove that adapts with the connecting rod profile on two pressure pads; The end of axle of being rotatably connected is rotationally connected with between two pressure pads.Fixing firm between two pressure pads and connecting rod can utilize a plurality of fastening bolts to reinforce the connection between bar and pressure pad and lift being connected between presser unit and linking unit, avoids the inclination that lifts Needle with pressure-increasing means or displacement that in art, the connecting rod rotational displacement causes.
Further, lift in presser unit, the fastening operating portion that lifts the pressurization axostylus axostyle is to be positioned at the hexagonal recess section that lifts pressuring shaft masthead section center, also can be arranged to quincunx, in utilizing when operation, hexagonal bottle opener or blossom type bottle opener can be realized moving up and down thereby drive lifts Needle with pressure-increasing means lifting the operation that turns of pressurization axostylus axostyle.
The beneficial effects of the utility model are: can match with the bone external fixation device of various different models on market, only need in art by the pressurization axostylus axostyle that lifts in this utility model is carried out along backward turning, can drive and lift Needle with pressure-increasing means and move up and down, realization lifting and pressurizeing fracture end, make fracture end to move up and down with lifting Needle with pressure-increasing means, realize effectively resetting; And no longer need other external force can keep the stable and pressurization of fracture end after resetting.Can reduce Treatment of nonunion, the incidence rate of nonunion alleviates patient's misery.And this utility model highly versatile, easy and simple to handle, very large generalization and practicality are arranged clinically.
