Description

The multifunctional assembled fracture of calcaneus external fixator that resets

Affiliated technical field

This utility model belongs to a kind of medical apparatus and instruments, especially relates to a kind of multifunctional assembled fracture of calcaneus external fixator that resets.

Background technology

The present Therapeutic Method of fracture of calcaneus is traction both at home and abroad, and sled is dialled and added external plaster fixation or wear the bone boots, adopts open reduction to add " claw-like " titanium steel plate, multiple screws art in recent years.But all there are many deficiencies in they: there are complication such as infection, flap necrosis, sensory disturbance in, operation undesirable as reset function, and what have also needs to carry out taking out second time fixture, increase patient's misery and financial burden.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that exists in the prior art means, provide a kind of combination type can arbitrarily dismantle combination, the multi-functional calcaneus of being convenient to operate and the adjust external fixator that resets, this fracture of calcaneus external fixator that resets is safe and reliable, simple in structure, and combined and instant is flexible, quick Wicresoft, reset and fixedly have both, easy to carry, economical and practical.

The technical scheme that its technical problem that solves this utility model adopts: fracture of calcaneus resets external fixator by 4 pieces of (individual) steinman pins, 4 pairs of telescopic shafts, a calcaneus folder, calcaneus obvolvent device and vola gripper shoe are formed, and it is characterized in that: be installed with telescopic shaft (4) and telescopic shaft (5) respectively on the shank of pin (1) and steinman pin (9) in this; Be installed with telescopic shaft (3) and telescopic shaft (6) again respectively on the shank of steinman pin (1) and steinman pin (12); Also be installed with telescopic shaft (2) and telescopic shaft (7) respectively on the shank of steinman pin (1) and steinman pin (10); Be installed with telescopic shaft (11) and telescopic shaft (25) respectively on the shank of steinman pin (10) and steinman pin (12).Blocks vola support backing plate (8) is fixed in welding in the middle of steinman pin bar (9).In the middle of steinman pin (12), the obvolvent device is installed, on the steinman pin bar (12) of the obvolvent device left and right sides, the calcaneus anchor clamps is installed.The calcaneus anchor clamps are by clamping plate (18), clamping plate (24), and support shaft (16), sleeve pipe (19), support connecting plate (17), tail Cuo (15), clamping plate push rod (13) and handle (14) constitute; The obvolvent device is by telescopic shaft (21), goes up on the sleeve pipe (30) at telescopic shaft two ends, is welded on obvolvent pawl (20) on sleeve pipe (30) termination and (22) and is welded on pipe (29) formation on the gripper (20).After patient's calcaneal tuberosity fractures " ∨ " shape to open, use this utility model can make the patient reduce misery and reset fast.Its concrete practice is: cross 1 piece of steinman pin (1) and steinman pin (10) at the distal tibial of suffering from limb with vertical each level position, cubitale center of suffering from foot respectively, pawl (20) with the obvolvent device, (22) calcaneal tuberosity is fractured two ends promptly, by rotating obvolvent device telescopic shaft (21), the obvolvent device is drawn in, the calcaneal tuberosity reduction of the fracture of compression flare up " ∨ " shape, then the pore (29) at obvolvent device one end pierces into steinman pin bar (12), the groove fork that calcaneus is pressed from both sides on two clamping plate is contained on the steinman pin bar (12) of obvolvent device both sides, under the effect of fixture mount, rotate pusher grip by hand, make clamping plate (18) to clamping plate (24) near closing up, the corpora calcanei fractured type compression of fracture and injury broadening is resetted, and one vola is set supports backing plate suffering from the whole end, support the centre that backing plate is welded on steinman pin bar (9), and steinman pin bar (9) and steinman pin bar (1) be on the same vertical coronalplane, such 4 pairs of telescopic shafts have been set on the shank at two ends, the left and right sides of 4 pieces of these pins, be combined into a fracture of calcaneus external fixator, and the telescopic shaft that will be sleeved on the steinman pin bar is as required adjusted.Till making it reach fracture of calcaneus satisfaction and reset.

The beneficial effects of the utility model are: each parts all can arbitrarily be dismantled combination, forms the external fixator that is suitable for the fracture of calcaneus different parts, fixes with steinman pin, telescopic shaft leads presses or the obvolvent of obvolvent device, fixed requirement had both been satisfied in the clamping plate extruding of anchor clamps, had less profile again, need not operate on operation, make the fracture of calcaneus rehabilitation, safe and practical, simple and easy to do, minimizing patient's misery, the satisfaction of curative effect, and alleviate patient economy burden.
