Abstract
The invention discloses an end plate leverage restorer for thoracic-lumbar vertebra reposition enchevillement bone-graft operation, which comprises a positioning rod, wherein one end part of the positioning rod is connected with an olive-shaped head part. The length L of an olive-shaped long shaft of the head part is 15-25mm, and the length D of an olive-shaped short shaft of the head part is 4-7mm. The positioning rod is provided with buckling, the angle of the buckling is 5-10 degrees, and the buckling of the positioning rod is preferably arc buckling. The end plate leverage restorer for thoracic-lumbar vertebra reposition enchevillement bone-graft operation is convenient for entering a bone hole by designing the head end into an olive-shaped dull head, automatically slides towards the vertebral pedicle cancellous bone cavity when advancing under the pushing, has an automatic seeking function without easily penetrating out of the front outer side wall of the vertebral pedicle cortical bone and the vertebra body, avoids damaging nerve roots, endorhachis sacs, belly cavity visceral organs and blood vessels, improves the operation safety, increases the activity range of the front end of the end plate leverage restorer when in leverage for restoring, and can be a restoring centrum cartilage end plate with a larger contact surface.
Description
Technical field
The present invention relates to a kind of bone surgery utensil, the reset soleplate sledge of bone grafting operation of a kind of breast lumbar vertebra of more specifically saying so is dialled positor, belongs to technical field of medical instruments.
Background technology
Lumbar vertebra compression fracture is common clinically spinal injury, its therapeutic purposes are recoveries and keep the spinal column normal sequence, rebuild the stability of spinal column, prevent that kyphosis deformity and tardy property paralysis from taking place, and the final functional rehabilitation of patient depends on the quality of the reparation and the union of fracture of vertebral height.Approach is simple because the employing posterior approach has, and wound is little, and the treatment operating time is short, and intraoperative hemorrhage is few, and rehabilitation is fast, and spinal stability reaches advantages such as no significant complications well.Therefore the breast lumbar vertebra resets and generally carries out in the bone grafting operation at home.The existing breast lumbar vertebra bone grafting operation that resets has generally earlier bored passage with screw tap on versus posterior vertebral, dial soleplate up and down with pedicle of vertebral arch open circuit awl sled in hindering vertebra of different radians down by this channel C arm perspective simultaneously, make reset satisfied and formation empty.Recover simultaneously to hinder the vertebra height, reset after the satisfaction, put into the bone grafting sleeve pipe, will push in the vertebral body bone grafting by overlapping effective bone grafting rod from body bone or artificial bone at working hole.In said method, sled is dialled and is generally selected for use the straight titanium rod of 5～6.5mm pedicle to stretch into vertebral body respectively, will compress sagging soleplate percutaneous reduction by leverage.Adopt the characteristics of straight titanium device of 5～6.5mm and vertebral body bone grafting device to be because sled is dialled: rod, pass pedicle of vertebral arch cortical bone and the preceding lateral wall of vertebral body during percutaneous reduction by leverage easily, there are operation safety hidden danger in injured nerve root, dural sac, splanchnocoel internal organs and blood vessel; The range of activity of its front end when percutaneous reduction by leverage is little again simultaneously, can not be than the vertebral body cartilage endplate that resets of large contact surface.
Summary of the invention
At the problems referred to above, the problem that quasi-solution of the present invention is determined is not easy to pass pedicle of vertebral arch cortical bone and the preceding lateral wall of vertebral body when providing a kind of percutaneous reduction by leverage, injured nerve root, dural sac, splanchnocoel internal organs and blood vessel, the reset soleplate sledge of bone grafting operation of the breast lumbar vertebra that simultaneously range of activity of its front end when percutaneous reduction by leverage is big is again dialled positor, to improve operation safety, can be than the vertebral body cartilage endplate that resets of large contact surface.
For achieving the above object, the present invention has adopted following technical scheme: the reset soleplate sledge of bone grafting operation of a kind of breast lumbar vertebra is dialled positor, and it comprises locating rod, and an end of described locating rod is connected with head, and described head is an olive shape.
The olive shape long axis length L of described head is the 15-25 millimeter, and the olive shape minor axis length D of described head is the 4-7 millimeter.
As improvement, another end of described locating rod is connected with handle.Described locating rod has bending, and the angle of described bending is ∠ a, and described ∠ a is the 5-10 degree, and the bending of described locating rod is preferably the arc bending that becomes the nature radian gradually.Described locating rod is provided with scale.
Adopt said structure, the reset soleplate sledge of bone grafting operation of breast lumbar vertebra of the present invention is dialled positor, when the breast waist resets the bone grafting operation percutaneous reduction by leverage, the percutaneous reduction by leverage utensil has olivary head, it is blunt nosed to be that head end is designed to olive shape, be convenient to enter the bone hole,, automatic tracking function arranged promoting to slide to pedicle of vertebral arch spongiosa bone cavity when advancing automatically; Be difficult for passing the preceding lateral wall of pedicle of vertebral arch cortical bone and vertebral body, avoid injured nerve root, dural sac, splanchnocoel internal organs and blood vessel, improve operation safety, this increases the range of activity of its front end when percutaneous reduction by leverage again because its face of olive shape is arc simultaneously, more the vertebral body cartilage endplate that resets of large contact surface.In addition, according to actual prying and pulling requirement, the olive shape long axis length L of design head is the 15-25 millimeter, and the olive shape minor axis length D of described head is the 4-7 millimeter.Make sledge of the present invention dial the operation needs that positor can be fit to the different characteristic patient like this.
In improvement project, another end of locating rod is connected with handle, makes things convenient for sledge to dial the operation of positor.Described locating rod has the bending that becomes the nature radian gradually, and the angle ∠ a of bending is the 5-10 degree, can cooperate the inserting needle inclination angle of performing the operation, the effect of raising percutaneous reduction by leverage.Described locating rod is provided with scale, can be so that the degree of depth that the control prying and pulling enter the breast lumbar vertebra.
Description of drawings
Fig. 1 is that the reset soleplate sledge of bone grafting operation of breast lumbar vertebra of the present invention is dialled the structural representation of positor.
Among the figure: 1-locating rod, 2-head, 3-handle, 4-scale.
The specific embodiment
As shown in Figure 1, the reset soleplate sledge of bone grafting operation of breast lumbar vertebra of the present invention is dialled positor, and it comprises locating rod 1, and an end of described locating rod 1 is connected with head 2, and described head is an olive shape.The olive shape long axis length L of described head 2 is the 15-25 millimeter, and the olive shape long axis length D of described head 2 is the 4-7 millimeter.
As the breast lumbar vertebra of the present invention improvement that the soleplate sledge of bone grafting operation dials positor that resets, another end of described locating rod 1 is connected with handle 3.Described locating rod 1 has bending, and the bending of described locating rod 1 is preferably the arc bending.The angle of described bending is ∠ a, and described ∠ a is the 5-10 degree, and angle is for becoming the bending of nature radian gradually.Described locating rod 1 is provided with scale 4.
