Abstract
The utility model belongs to the technical field of a medical apparatus, particularly a fracture incision reduction pressurizer for fracture reduction and fracture end pressurizing to eliminate gaps. The pressurizer is mainly composed of a longitudinal regulating supporter, an adjustable left-side bone holder and an adjustable right-side bone holder. The utility model can correct the top, the bottom and the side displacements of a fracture end, and can also correct the superposition and the angulation displacement of a bone broken end, and simultaneously play the longitudinal pressurizing function. The utility model can be used for causing the exposure range of operation to be small and tissue wound to be light, without the need of special apparatuses; the utility model is used for various types of steel plates, screws and intramedullary needles, and is suitable for various fracture operations of limbs.
Description
This utility model belongs to the medical apparatus technical field, particularly a kind of fracture open reduction prelum for the reduction of the fracture and fracture end pressurization elimination gap.
Usually use bone holder, bone holder to carry out the reduction of the fracture in the extremity fracture operation, steel plate, screw or intramedullary needle are fixed.The former has only fixedly fracture site and steel plate effect, can not carry out the reduction of the fracture, and the latter can only the clamping bone stump, steel plate and bone stump can not be fixed together.And two kinds of apparatuses all do not have vertical pressurization, promptly can not eliminate the fracture site gap, easily cause the bone stump gap to widen when intramedullary needle is squeezed into yet.Before this utility model, existing several reseting fixtures that are used for fracture operation are as CN93211480.6 reduction of the fracture machine; The CN92222698.9 inside fixing reset unit; CN91224943.9 fracture operation reduction fixture device etc.Above-mentioned three kinds of positor structure more complicated, and also do not have vertical pressurization.External produce a kind of automatic pressurized bone plate, the main screw hole that changes it and the shape of nut of relying on makes it produce compression stress automatically in screw screw-in process, and this self pressurization can make fracture gap dwindle 2-3 millimeters.Other has a kind of type blade plate that pressurizes is with screw one end of prelum temporarily to be fixed in the backbone, and its other end hooks the terminal screw hole of blade plate, pressurizes with wrench, and the bone section is embedded in together mutually.Above-mentioned apparatus does not have reduction of the fracture effect, needs bigger surgical exposure scope and the special apparatus of a cover.For defective and the deficiency that overcomes in the prior art designed a kind of new multi-functional fracture open reduction prelum.
The purpose of this utility model is that a kind of multi-functional fracture open reduction prelum of design is used for extremity fracture open reduction steel plate or intramedullary nailing, correct bone stump cripetura and angulation displacement and have the vertical pressurization of bone stump, make bone stump tightly involutory, help union of fracture.
Main points of the present utility model are: be used for the multi-functional fracture open reduction prelum in the reduction of the fracture, fracture end pressurization elimination gap, it includes one and vertically regulates support, an adjustable left side bone clamper and an adjustable right side bone clamper.Regulate left and right side seam clamper and can correct the upper and lower and lateral displacement of fracture end, regulate vertical support of regulating and to correct the overlapping and angulation displacement of bone stump, play vertical pressurization simultaneously, make bone stump tightly involutory.
Below in conjunction with drawings and Examples this utility model is described in further detail.
Fig. 1 is multi-functional fracture open reduction prelum structural representation.
Fig. 2 is the structural representation of adjustable left side bone clamper.
Fig. 3 is the structural representation of adjustable right side bone clamper.
Multi-functional fracture open reduction prelum of the present utility model is vertically regulated support (1), an adjustable left side bone clamper (2) and an adjustable right side bone clamper (3) by one and is formed.
Vertically regulating support includes one pair of laterally zygomorphic (6) central screw of quadric chain (7) that connect by pin uranium (4) (5) and passes across bearing pin (4) and connect with pin uranium (5) horizontal thread.The front end of central screw is threaded with the female thread transverse holes of bearing pin (5) and matches.Two pairs of nodes in addition of four connecting rods connect with left cramp bar (8) and right cramp bar (9) respectively by pin (10) (11).Left side cramp bar has an outer side slot and the degree of tightness of two screw scalable outer side slots is arranged, and when screw takes off, left side bone clamper can be taken out, and is convenient to a left side and holds the bone chuck and be placed on the bone stump.Two pairs of free-knot ends of four connecting rods connect up and down by pin (12) (13) respectively and can be respectively at elongated slot (14) (15) inside groove of left cramp bar and right cramp bar to moving.The rotation center screw rod can drive relative distance that quadric chain makes left cramp bar and right cramp bar in vertical variation, even whole vertical adjustable support plays the regulating action of longitudinal pitch by pin uranium (5).
Adjustable left side bone clamper includes a left side and holds bone bar (16), it is placed in the outer side slot of left cramp bar, a left side is held the bone bar and is had lateral adjustments screw rod (17), screw rod and left screw-internal thread fit of holding the bone rod rear end, the lateral displacement of bone bar is held on a scalable left side during rotation, makes a whole left side hold the bone bar and laterally moves in the outer side slot of left cramp bar.The front end that the bone bar is held on a left side has left activity to hold bone chuck (18) and be connected with it by screw (19), and left activity is held when having an elongated slot (20) for the adjusting front and back position on the bone chuck and used.
Adjustable right side bone clamper is attached on the right cramp bar by screw (21) (22), and right side bone clamper comprises the right side, back and holds bone bar (23) and (24) two sections on bone bar is held on the preceding right side.Hold the bone bar and be connected for above-mentioned two sections with screw (25).Right activity is held bone chuck (26) and is held the bone bar by the screw (27) and the right side and be connected, right activity is held when also having elongated slot (28) for the adjusting front and back position on the bone chuck and is used, the rear end that the bone bar is held on the right side has up-down adjustment bolt (29) bolt and cooperates with the spiral shell nurse, hold the upper and lower displacement of bone bar during rotation by the squeeze adjustments right side of spiral shell nurse and right cramp bar, make the whole right side hold the bone bar and return to a left side and hold bone bar parallel position.
Each parts of this multi-functional fracture open reduction prelum all select for use stainless steel material to make.
Bone clamper lateral attitude, the left side scalable of multi-functional fracture open reduction prelum of the present utility model, the upper and lower position of right side bone clamper is scalable also, also scalable, the vertically adjustable support adjusting length travel in addition of front and back position of bone chuck held in left and right activity.So both can correct the upper and lower and lateral displacement of fracture end, can correct the overlapping and angulation displacement of bone stump again, play vertical pressurization simultaneously, use this prelum that resets to make the surgical exposure scope little, tissue injury is light, do not need special instrument, all types of steel plate screws, intramedullary needle all can be used, and are applicable to all kinds of fracture operations of extremity.
