Abstract

The utility model relates to a reposition apparatus for lumbar vertebrae, mainly comprising column racks fixed to the edges of a bed, sliding column sleeves, levers hinged to the sliding column sleeves, pressure-heads inserted in middle holes of the levers and springs positioned between the pressure-heads and the levers. On the occasion of treatment, a rubber pad with V-shaped grooves is placed on lumbar spinous processes of the patient, and the pressure-heads are placed on the rubber pad; the levers being operated, thrust forces are exerted on the lumbar spinous processes through the springs and the pressure-heads; the purpose of reposition is achieved. The reposition apparatus is mainly used for reposition of lumbar spondylolisthesis, and can be also used for treatment of prolapse of lumbar intervertebral disc and acute lumbar muscle sprain.

Description

Apparatus for reducing lumbar vertebrae

This utility model belongs to orthopaedic instrumentation, is a kind of positor that is mainly used in lumbar spondylolisthesis.

At present, for the treatment of lumbar spondylolisthesis, clinically manual reductions that adopt also have the employing manual reduction to treat to some lumbar intervertebral disc prolapse more.But this manual reduction is entirely with doctor's experience, the bad grasp of the dynamics of hands when resetting, and effort very.

The purpose of this utility model provides a kind of lumbar vertebra positor that can replace manual reduction.

The solution that realizes this utility model purpose is: the lumbar vertebra positor that is provided is hinged on lever, shank on this sliding sleeve by a support that has column that can be fixed on bedside, sliding sleeve, end that is enclosed within on this column and inserts pressure head in the lever mider hole, is positioned at the spring between lever and pressure head and is positioned at the pressure head following table and wear the rubber blanket of V-shaped groove and form, wherein locate by pin between sliding sleeve and the column, the shank of pressure head is carved with and shows the power scale.During use rubber blanket is placed on the spinous process of lumbar vertebra of dislocation, pressure head is pressed on the rubber blanket, and other people hand the downward application of force of lever, and this power passes on patient's the spinous process of lumbar vertebra by lever, spring and pressure head, reaches the purpose of treatment.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the another kind of structure chart of this utility model pressure head.

As shown in Figure 1: support 1 comprises column 2 and base 3 two parts, and wherein base 3 is L shaped, may be stuck in bedside or is fastened on bedside with screw.Sliding sleeve 5 is enclosed within on the column 2, and locatees with pin 6.Column 2 is provided with string pin-and-hole 4, in order to regulate the height of sliding sleeve 5, so that adapt to the needs of different human body.Lever 7 is hinged on the sliding sleeve 5 by bearing pin 8, and a billiard table 9 with holes has been welded at its middle part, and the shank 12 of pressure head 10 inserts in the hole of billiard table 9, and carries out axial location with pin 13.Be provided with a compression spring 14 between pressure head 10 and the billiard table 9, it had both played a part the downward application of force, played cushioning effect again.During treatment, will be with the rubber blanket 15 of V-shaped groove to be placed on patient's the spinous process of lumbar vertebra, the actuating linkage 7 downward application of forces be carried out reduction therapy.The big I of the application of force is found out by the scale 11 of pressure head shank 12.When being used as normotopia and resetting, the lower surface of pressure head 10 is the plane; When being used as the side position and resetting, should adopt pressure head shown in Figure 2 16, its lower surface is the garden curved surface of column.

This utility model is easy to use, leicht fallen D/A, and also the application of force is accurately, intuitively; Because the application of force undertaken by spring, have cushioning effect, thus this application of force process safety not only, and dynamics is grasped easily.

Claims

1, a kind of lumbar vertebra positor, it is characterized in that the support that has column 21 that can be fixed on bedside by one, a sliding sleeve 5 that is enclosed within on this column 2, the end is hinged on lever 7 on this sliding sleeve 5, shank 12 and inserts pressure head 10,16 in levers 7 mider holes, is positioned at the spring 14 of 10,16 of lever 7 and pressure heads and is positioned at pressure head 10,16 following tables and wear the rubber blanket 15 of V-shaped groove and form, wherein locate by pin 6 between sliding sleeve 5 and the column 2, the shank 12 of pressure head 10,16 is carved with and shows the power scale.

2, lumbar vertebra positor as claimed in claim 1, the lower surface that it is characterized in that said pressure head 10 is the plane.
