Description
Technical field
The present invention relates to a kind of traction apparatus, particularly a kind of traction resetting device that uses when the fracture of tibia and fibula closed reduction is performed the operation can be realized accurate traction, a kind of medical traction resetting device for treating bone fracture that resets.
Background technology
Along with rapid development of national economy, it is more and more flourishing, more and more busier that traffic becomes, and the various sudden hurt accidents of Yin Faing are also more and more frequent thus.In these accidents, fracture is a kind of modal injury.In order to treat timely and effectively to fracture patient, many hospitals (from the provincialism large hospital to all kinds of County Hospital) all set up or perfect orthopaedic trauma, and the treatment of fractures technology is also progressive and perfect constantly, developed into modern all kinds of internal fixations such as intramedullary pin from traditional traditional Chinese medical science synthetism, increasing new technique is used in the treatment of fractures.
In fractures operation, the reduction by traction operation be one basic, also be very important operation simultaneously, its effect directly influences surgical outcome and post-operative recovery.Traction is meant for the position after the fracture, by apply the opposite power of direction at the fracture two ends, will roll over the operation that the bone tractive separates.Resetting is meant after traction, will roll over bone recovery to the operation near the position under the health status.In the operation of traditional fractures, draw and the operation that resets all be by the doctor with reference to art before or fluoroscopy images in the art, by virtue of experience, free-hand finishing.Such operation is not only complicated but also very depend on doctor's clinical experience.In addition, the doctor also usually needs to be directly exposed under the X-ray to operate, and has increased the dosage of doctor's raying.
At present, in fracture of tibia and fibula closed reduction intramedullary nail with lock internal fixation operation, the traction of fracture and reset and basic rely on that the doctor is free-hand to finish not have the special traction apparatus that designs at this operation.
Because in the prior art, the traction of fracture and reset and rely on that the doctor is free-hand to finish substantially, this is a job of wasting time and energy to operative doctor, and because the unstability of the staff application of force, draws and the effect that resets can not guarantee.And in operation,, suffer from limb and will take enuflex position, in present operation, often have a doctor to suffer from limb, make it keep enuflex position with two-handed hand-held carrying out intramedullary pin when going into the nail operation.This not only consumes a large amount of muscle power of doctor, and free-hand controlling can not guarantee to suffer from the stability of limb in operation technique.
Summary of the invention
Technical problem to be solved of the present invention is to provide a kind of traction resetting device for treating bone fracture at deficiency of the prior art, and this device can provide the stable support of trouble limb, and makes it keep enuflex position, is convenient to operation technique; This device has the electric traction function, and operative doctor just can be finished the reduction by traction of doubling bone as long as press movement controller, adds the scale location in the device, has improved the degree of accuracy that resets.
For this reason, the invention provides a kind of traction resetting device for treating bone fracture, comprise the support that is used to keep suffer from the enuflex position of limb, this support comprises panel that an end of base plate, an end and this base plate articulates and the adjusting parts that are used to adjust angle between described panel and base plate; Described panel upper end is provided with suffers from the limb eyelid retractor; Described panel lower end is provided with the reduction by traction module that is used to provide pull strength.
In the technique scheme, the reduction by traction module comprises a motor; The driving shaft of described motor is connected with driver, be provided with the rotation that to follow described motor in this driver and carry out the draw bar that axial stretching moves, this draw bar one end is arranged in the inner drive disk assembly with driver of driver and is connected with a joggle, the other end is positioned at the driver outside, and the traction bow that is used to articulate " U " font of suffering from limb is installed; Two arms of described traction bow are provided with the clamping member of the Kirschner wire that is used for clamping traction operation usefulness.
The input of above-mentioned motor also is connected with the outfan of the controller that is used to control described motor action.
Traction resetting device for treating bone fracture of the present invention at first has adjustable triangular support structure, the angle that can support according to different patients' concrete condition adjustment, like this can be in fracture of tibia and fibula closed reduction intramedullary nail with lock internal fixation operation, provide suffering from the stable support of limb, and make it keep enuflex position, be convenient to operation technique; In addition, this device has the electric traction function, as long as the button that operative doctor is pressed on the manual controller just can be controlled the reduction by traction that this device is finished the doubling bone, has both improved the effect of traction, has alleviated doctor's operation technique fatigue again.Add the scale location in the device, improved the degree of accuracy that resets.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
