Abstract
Disclosed is an outside fixable device for inside anklebone fracture. The upper part of a claw hook-shaped reinforced plate is provided with an open groove, a nut block is fixed on the upper part of the reinforced plate and is inserted in the open groove, a compression screw screws in and passes through the nut block from upper to lower, a V-shaped sliding block gores the lower part of the compression screw, and the lower part of a V-shaped groove is provided with a fixed screw plumbing to the reinforcing plate. When the utility model is used, the claw hook hooks the far-end of a bone block, the fixed screw passes through a shank bone, and then, screws the compression screw tightly, and makes the breaking end side of a bone endured certain pressure. The utility model is convenient treating and can make bone fracture healed in advance.
Description
This utility model belongs to medical apparatus and instruments, specifically a kind of external fixator for the treatment of the displacement fracture of medial malleolus.
To the fracture of medial malleolus of displacement is arranged, traditional Therapeutic Method is an open reduction, the screw internal fixation, external plaster fixation, after the broken ends of fractured bone healing again surgical incision take out screw.
This utility model is that a kind of novel fixture for the treatment of fracture of medial malleolus will be provided, and it can exempt complicated cutting operation and external plaster fixation.
This utility model is achieved in that whole device is made up of claw hook shape gusset plate, forcing screw, nut block, V-arrangement slide block and hold-down screw etc.Claw hook shape gusset plate main part is a template, and top has an open slot, and the bottom is two claw hooks; A nut block is fixed on claw hook shape gusset plate top by two Screws, and its projection is embedded in the open slot of claw hook shape gusset plate; A forcing screw screws in and passes nut block from top to bottom; A V-arrangement slide block withstands on the forcing screw bottom, and its both sides have guide groove, with the embedding mutually of claw hook shape gusset plate open slot, and can slide relatively with gusset plate; A hold-down screw is in the V-shaped groove bottom of V-arrangement slide block, and it is vertical with claw hook shape gusset plate plane and pass open slot.During use, earlier two claw hooks being hooked bone piece far-end resets, after the para-position, hold-down screw is laterally screwed in and pass tibia to bone offside cortex, turn forcing screw then, be screwed into 3～4 pitch after tightening again, under the effect of nut block, claw hook shape gusset plate moves up, because the position of hold-down screw is constant, therefore the distance between claw hook and hold-down screw reduces, and makes the bone section be subjected to certain pressure.
This utility model is simple in structure, easy to use, outpatient service can be treated, only cause 3 dermal pores, the infection of having avoided operation and operation to bring, the pressurization after the para-position, can prevent the strain activity that bone stump produces because of early stage surface absorbs and the change of width, and can liberate the joint in early days, walk, than traditional therapy 3～4 weeks healing in advance followingly.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is that the B-B of Fig. 1 is to view.
Fig. 4 is a nut block of the present utility model.
Fig. 5 is a V-arrangement slide block of the present utility model.
(1) be claw hook shape gusset plate, (2) are forcing screws, and (3) are nut block, and (4) are the V-arrangement slide blocks, and (5) are hold-down screws, and (6) are 2 * 6mm Screws.Forcing screw among the figure (3) is in the position after the pressurization.
An open slot is driven on claw hook shape gusset plate (1) top, the bottom is two claw hooks, nut block (3) is fixed on the gusset plate by two Screws (6), its projection is embedded in the gusset plate open slot, forcing screw (2) screws in and passes nut block (3) from top to bottom, V-arrangement slide block (4) withstands on forcing screw (2) bottom, its both sides have guide groove, open slot embedding mutually with claw hook shape gusset plate (1), and can relative slip with gusset plate (1), its effect be under the restriction V-shaped groove hold-down screw (5) swing moving.The using method of device is as follows: according to the projection of internal malleolus the template of claw hook shape gusset plate (1) partly is converted into corresponding radian, under the perspective situation, claw hook hooks bone piece far-end and resets, after the para-position, hold-down screw (5) is laterally screwed in and passes tibia to bone offside cortex, turn forcing screw (2) then, be screwed into 3～4 pitch after tightening again, under the effect of nut block (3), claw hook shape gusset plate (1) moves up, because the position of hold-down screw is constant, so the distance between claw hook and hold-down screw (5) reduces, and makes the bone section be subjected to certain pressure.
Claw hook shape gusset plate of the present utility model adopts the slim stainless steel material of not electric Jie's property in the body.
The claw hook part of claw hook shape gusset plate of the present utility model can be processed into different sizes according to the size of adult, child's skeleton.
Claims (2)
1, a kind of fracture of medial malleolus external fixator is made up of claw hook shape gusset plate, forcing screw, nut block, V-arrangement slide block, hold-down screw, it is characterized in that:
A, claw hook shape gusset plate top have an open slot, and the bottom is two claw hooks.
B, a nut block are fixed on the top of claw hook shape gusset plate by two Screws, and its projection is embedded in the open slot of claw hook shape gusset plate.
C, a forcing screw screw in and pass nut block from top to bottom.
D, a V-arrangement slide block withstand on the forcing screw bottom, and its both sides have guide groove, with the embedding mutually of claw hook shape gusset plate open slot, and can with relative slip of claw hook shape gusset plate.
E, a hold-down screw be in the V-shaped groove bottom of V-arrangement slide block, and it and claw hook shape gusset plate plane are perpendicular and pass open slot.
2, device according to claim 1 is characterized in that claw hook shape gusset plate adopts stainless steel material.
