Subcutaneous putting described in the utility model buried the type breast lumbar vertebra nail rod staple that resets and had following characteristics:
(1), project organization is reasonable, nail-stick system stability is good;
(2), the nail rod struts the strength abundance, the compression vertebral body ideal that resets;
(3), X line perspective is located the operation of percutaneous Wicresoft, reduction operation risk, minimizing patient suffering.Substantially do not damage waist muscle, guaranteed the stability of waist muscle.Be convenient to carry out treatment, the nursing of waist, it is good that vertebral fracture recovers;
(4), nail-stick system places subcutaneously, infection risk is little, the patient is easy to carry, second operation is easy and simple to handle, the patient suffering is little, spends low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is to use state reference map.
Among the figure: 1, add the silk pressing medicated cap, 2, the location faces directly, 3, tubular pressurization lock body, 4, the pressure bar mouth, 5, screw thread, 6, anti-rotation faces directly, 7, the excellent hole of microscler lock, 8, the nail body, 9, the screw thread ailhead, 10, vertebral body, 11, vertical rod.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
It comprises nail body 8 as accompanying drawing 1, and the front portion of nail body is a screw thread ailhead 9, and the afterbody of nail body 8 is provided with the excellent hole 7 of microscler lock that is used to pass locating bar, and 7 bottoms, the excellent hole of microscler lock are one oblique.On the nail body 8 on 7 tops, the excellent hole of microscler lock, be with tubular pressurization lock body 3, screw thread 5 be set and add silk pressing medicated cap 1 in the tail end end of nail body.Have anti-rotation and face 6 directly on the microscler lock nail body in 7 one weeks of excellent hole, in tubular pressurization relative both sides, lock body 3 bottoms pressure bar mouth 4 is set, the tubular pressurization lock body on pressure bar mouth 4 tops is inboard for facing 2 directly in the location, anti-rotation face directly 6 and the location face 2 relative engagement directly.
Using method as shown in Figure 2: spinal column 7 homonymies two are main to be followed closely after pedicle is squeezed into the vertebral body correct position respectively, one vertical rod 11 is after the two main nail excellent holes 7 of the microscler lock of tail end and tubular pressurization lock body 3 are connected to one group, two main nail tail ends add the 1 row pressurization of silk pressing medicated cap, because 7 bottoms, the excellent hole of microscler lock are one oblique, two main nails are strutted, and vertebral body 7 resets.Respectively there is one group of master's nail the spinal column both sides, form fixed system.Generally do not use horizontal company.
Its concrete operations are as follows:
1, four of breast lumbar vertebra single-shot fractures nails two rod fixing meanss: conventional partly sterilised, drape, select local anesthesia, under X line perspective, need to determine the position of the pedicle of vertebral arch of vertebral body at body surface, earlier with the selected suitable direction of puncture depth measurement guide pin, by skin through muscular tissue, through the vertebral body pedicle of vertebral arch entry point position that determine to need.Determine skin to the distance of entry point, puncture needle is worn out sclerotin and is done the location.Along puncture place, the about 1.0cm of longitudinal incision skin.Use hollow gag, enter subcutaneous and tissue through guide pin, visit and pedicle of vertebral arch entry point sclerotin after, suitably the rotary drilling matter that opens seam is firmly extracted the depth measurement guide pin out.Use the depth measurement probe,, visit sclerotin, measure depth of probe through hollow gag.Use special sleeve pipe,, reach sclerotin,, extract probe and hollow gag out with hands fixed-direction and position along hollow gag.With the definite main nail of full dog point socket set broach shell selected in advance surely diameter, length.Through special sleeve pipe, along the opening part of pedicle of vertebral arch entry point, press certain orientation, screw in screw thread ailhead 9.Same quadrat method screws in other three pieces of main nails successively in the spinal column both sides.About two vertical rods 11 respectively through the skin otch, penetrate in that homonymy is subcutaneous, reach homonymy piece main ailing tail in addition.Adjust two main nail excellent holes 7 of the microscler lock of tail end and tubular pressurization lock body 3 positions, the vertical rod 11 of locking is formed the fixed reset system.Two groups of masters follow closely tail end and add silk pressing medicated cap 1 and screw tight pressurization, and two groups of masters' nails just strut, and compression vertebral body 10 resets.Postoperative film making, determine position suitable after, normal saline cleans four skin incisions, check dressing and apparatus errorless after, sew up the incision, art finishes, conventional aseptic dressing covers wrapping.
2, many nails two rod fixing meanss of breast lumbar vertebra multiple fracture treatment: conventional partly sterilised, drape, select local anesthesia, under X line perspective, need to determine the position of the pedicle of vertebral arch of vertebral body at body surface, earlier with the selected suitable direction of puncture depth measurement guide pin, by skin through muscular tissue, through the vertebral body pedicle of vertebral arch entry point position that determine to need.Determine skin to the distance of entry point, puncture needle is worn out sclerotin and is done the location.Along puncture place, the about 1.0cm of longitudinal incision skin.Use hollow gag, enter subcutaneous and tissue through guide pin, visit and pedicle of vertebral arch entry point sclerotin after, suitably the rotary drilling matter that opens seam is firmly extracted the depth measurement guide pin out.Use the depth measurement probe,, visit sclerotin, measure depth of probe through hollow gag.Use special sleeve pipe,, reach sclerotin,, extract probe and hollow gag out with hands fixed-direction and position along hollow gag.With the definite main nail of full dog point socket set broach shell selected in advance surely diameter, length.Through special sleeve pipe, along the opening part of pedicle of vertebral arch entry point, press certain orientation, screw in screw thread ailhead 9.Same quadrat method is squeezed into several pieces of main nails in addition successively in the spinal column both sides.About two vertical rods respectively through the skin otch, penetrate in that homonymy is subcutaneous, reach homonymy several pieces of main ailing tails in addition.Adjust main nail excellent hole 7 of the microscler lock of tail end and tubular pressurization lock body 3 positions, the vertical rod 11 of locking is formed the fixed reset system.Two groups of masters follow closely tail end and add silk pressing medicated cap 1 and screw tight pressurization, and two groups of masters' nails just strut, and a plurality of compression vertebral bodys 10 reset.Postoperative film making, determine position suitable after, normal saline cleans several skin incisions, check dressing and apparatus errorless after, sew up the incision, art finishes, conventional aseptic dressing covers wrapping.
