Description

Light multipurpose is free to slide the fracture traction frame

This utility model relates to a kind of medical fracture traction frame.

Traction frame is a treatment tool commonly used the most basic in treatments such as orthopaedic disease or fracture traction.Usually large hospital all is equipped with special extension table, its cost height, and heaviness moves inconvenient.Some hospital then adopts simple and crude method, promptly uses the wooden stick built on ordinary hospital bed, hangs up pulley and also can play draw.But this structure is very unrefined, and loading and unloading inconvenience, and its draw can only do the vertical fixing traction, can't be free to slide, and when the patient need change position, medical personnel's assistance just must be arranged had not only increased nursing work load but also increased patient's misery.

The purpose of this utility model is exactly in order to address the above problem, and a kind of structure small volume and less weight is provided, and cost is low, and is elegant in appearance, and light multipurpose easy for operation is free to slide the fracture traction frame.

Technical solution of the present utility model:

A kind of light multipurpose is free to slide the fracture traction frame, it is characterized in that it is made up of mobile jib (1), skull traction mechanism (2), lower limb traction mechanism (3) and bindiny mechanism (4), bindiny mechanism (4) is arranged on mobile jib (1) both sides, they link to each other with bedstead two side levers of sick bed one end by loading and unloading part, skull traction mechanism (2) at mobile jib (1) middle part is made up of support (5), secondary bar (6) and sliding shoe (7), is provided with a lower limb traction mechanism (3) that is made up of movable sleeve (8), connecting rod (9) and pulley (10) at least in a side of mobile jib (1).

This utility model is provided with roller assembly, make patient's incidence can freely change the position, but arbitrary load is used at ordinary hospital bed, not only can be used for the skull traction of fracture-dislocation of cervical spine, the traction of cervical spondylosis, also can be used for pelvic traction, lower limb traction and the outer exhibition position traction of lower limb extreme etc.This utility model is simple in structure, and compact volume and convenience is elegant in appearance, and is with low cost, can use at ordinary hospital bed, can arbitrarily load and unload, and the side of occupation of land not, especially to fracture-dislocation of cervical spine, or other is former thereby implement in the skull traction therapeutic, more can embody its superiority.Solved a difficult problem that needs 3-4 position nursing staff just can finish when fracture of cervical vertebra patient in the past or paraplegia patient stand up, the patient is the slip-on head cervical region arbitrarily, only needs two nurses' assistance to get final product when standing up, and is very easy to use.

Fig. 1 is a structural representation of the present utility model.

As Fig. 1, secondary bar (6) two ends in this utility model skull traction mechanism (2) are fixedly connected with corresponding two places at mobile jib (1) middle part by support (5), its sliding shoe (7) is made up of upper and lower two orthogonal whole U matrix (11), (12) and roller (13) and pulley (14), roller (13) links to each other with last U matrix (11), secondary bar (6) is from passing between them, making sliding shoe (7) to go up at secondary bar (6) slides, pulley (14) links to each other with following U matrix (12), and the pull rope that is used for drawing with patient's skull traction bow links to each other.Preferably respectively be provided with a lower limb traction mechanism (3) in mobile jib (1) both sides,, needn't unload lower rhabd (1) commutation installation by reuse to adapt to the needs of patient's two limbs respectively.Movable sleeve (8) movable set in the lower limb traction mechanism (3) is on mobile jib (1), and its lower end links to each other with pulley (10) by connecting rod (9), and movable sleeve (8) is provided with screw-threaded coupling pin (15).Bindiny mechanism of the present utility model (4) is made up of two sleeve pipes (16), adjustable turning-bar (17) and Hough spare (18), two sleeve pipes (16) are orthogonal two sleeve pipes, they are an integral body, wherein a sleeve pipe movable set is on mobile jib (1), the adjustable turning-bar of movable set (17) in another sleeve pipe, and be equipped with screw-threaded coupling pin (19) separately on two sleeve pipes of two sleeve pipes (16), fix their positions on mobile jib (1) and adjustable turning-bar (17) to regulate respectively.Can be connected with a rotatable lower limb traction mechanism downwards at mobile jib (1) one end, it is made up of vertical link (20), horizontal steering spindle (21) and pulley (22), vertical link (20) upper/lower terminal is connected with upper and lower sleeve pipe (23), (24), sleeve pipe on it (23) and mobile jib (1) one end pivot bush unit, setting of casing (24) and horizontal steering spindle (21) pivot bush unit, be equipped with screw-threaded coupling pin (25) on this upper and lower sleeve pipe (23), (24), pulley (22) links to each other with horizontal steering spindle (21) one ends by link.

When this utility model uses according to the width of bed body one side bedstead, two sleeve pipes (16) of regulating in the bindiny mechanism (4) are locked to the appropriate location and with screw-threaded coupling pin (19), then two Hough spares (18) are fixedlyed connected with bedstead two side lever relevant positions, it is fixed that its setting height(from bottom) is come according to needs of patients, and mobile jib (1) just fuses with bedstead like this.

When if the patient needs skull traction, with the pull rope of drawing on the skull traction bow on the pulley (14) of skull traction mechanism (2), its other end is connected with balancing weight, when needing side direction, the patient stands up when mobile, by pull rope roller (13) is slided along secondary bar (6) to a corresponding side, make the fracture of cervical vertebra patient freely to stand up, when needing longitudinal translation as if such patient, go up slip by pull rope and balancing weight at pulley (14), regulate patient's lengthwise position.The patient both can random mobile neck location like this, can guarantee that again traction is remaining the vertical distraction direction.

When if the patient needs lower limb traction, the movable sleeve (8) of lower limb traction mechanism (3) is transferred to corresponding patient's lower limb position and lock with screw-threaded coupling pin (15), the pull rope of drawing on patient's lower limb traction bow is walked around pulley (10), its other end is connected with balancing weight, finishes vertically moving of patient's lower limb by the weight of balancing weight.

When work as the bigger traction of patient's lower limb need abduction angle for receiving malunion in preventing to fracture, can finish by removable lower limb traction mechanism, the last sleeve pipe (23) of its vertical link (20) is adjusted to correct position also with its screw-threaded coupling pin (25) locking at mobile jib (1) one end, horizontal steering spindle (21) in its setting of casing (24) also transfers to correct position and locks with its screw-threaded coupling pin (25), pull rope on patient's lower limb traction bow is walked around pulley (22), its other end is connected with balancing weight, finishes vertically moving after patient's lower limb abduction by the weight of balancing weight.
