Abstract
The invention discloses a fixed-wing tubular wire retractor for percutaneous implantation under direct vision. The fixed-wing tubular wire retractor mainly comprises a wire retractor main body, and a handle connected to one end of the wire retractor main body, wherein an upper channel of the wire retractor main body is a first connecting rod lead-in groove; a far-end channel is a second connecting rod lead-in groove; a triangular pointed-end fixing end is arranged at the tail end of an inner side wing; an M-shaped fixing end is arranged at the tail end of an outer side wing. The fixed-wing tubular wire retractor is convenient to fix, wide in operation visual field and convenient for surgical operation.
Description
Technical field
The present invention relates to medical equipment technical field, particularly relate to a kind of fixed-wing tubulose drag hook for looking at lower percutaneous implantation straight.
Background technology
Lumbar-thoracic spine pedicle screw internal fixation meets the three-dimensional of spinal biomechanics to be fixed, and is now widely used for clinical treatment fracture dislocation of spine, lumbar spondylolisthesis, deformity of spine etc..The development of apparatus kind is various, but its common ground all uses pedicle screw, reaches vertebral body from rear pillar pedicle, except that the apparatus connecting fixing pedicle screw is different；Although current apparatus is varied, but it is cumbersome to seem in use, operation is inconvenient or blocks sight line, the particularly shape of fixed-wing tubulose drag hook front end does not matches due to the transverse process thick with human lumbar zygapophysis, thoracic vertebra, well drag hook can not be fixed, it is not easy to pitman and holds walking of rod device, have impact on being smoothed out of operation, for this, we devise a kind of fixed-wing tubulose drag hook inserting breast waist section pedicle screw for looking at lower percutaneous straight, the easy articular process with human body in the front end of its drag hook is fixed, it is simple to the carrying out of operation.
Summary of the invention
It is an object of the invention to provide a kind of fixed-wing tubulose drag hook for looking at lower percutaneous implantation straight.
It is an object of the invention to be achieved through the following technical solutions, this fixed-wing tubulose drag hook mainly includes drag hook main body, and it is connected to the hands handle of drag hook main body one end, described drag hook main body is the cylindrical shape being made up of a side opening the inboard wing of arc and ala lateralis, the upper channel of its drag hook main body is that the first pitman lead-in groove is walked with holding rod device for pitman, and surgical field of view can be increased, the passage of distal section is the second pitman lead-in groove, pass freely through for pitman, inboard wing end is provided with the fixing end (being similar to the head of laminectomy retractor) of a triangular pointed, can be fixed on inside articular process of lumbar vertebra, prevent drag hook from sliding；Ala lateralis end is provided with the fixing end of " M " type, can straddle on the transverse process that thoracic vertebra is thick, prevent drag hook from sliding.
The using method of this fixed-wing tubulose drag hook: on patient's prone operation platform, under anteroposterior position X-ray examination, determine the body surface projection of pedicle of vertebral arch central point with localizer, and make marks.Routine disinfection drape, at outer 0.5cm～1.0cm of labelling point, it is about the stringer skin incision of 2.0cm, cuts fascia thoracolumbalis, peel off gently along direction to the midline, musculus longissimus surface by two vascular forcepss in gap under fascia, enter paraspinal muscle gap, separate to facet joint from paraspinal muscle gap.Expanded casing is directly put to articular process, inserts expanded casing step by step, insert tubulose drag hook along sleeve pipe, exit expansion sleeve, look at menisectomy straight through tubulose drag hook.Set up pedicle screw trajectory, put into 2.5mm Kirschner wire, after C-arm perspective position is satisfied, looks at lower tapping straight, be screwed into pedicle screw (percutaneous cervical arc root screw, conventional pedicle screw).With method, other pedicle screws are installed.Laying suitable pitman through pitman lead-in groove A, B, jackscrew is fixed.Conventional closedown operative incision.
Beneficial effects of the present invention: this fixed-wing tubulose drag hook is easy to fix, and surgical field of view is open, operation technique is convenient.
Accompanying drawing explanation
Describe embodiments of the invention below in conjunction with the accompanying drawings in detail
Fig. 1 is the structural representation of the present invention
In figure: 1, the first take over the baton lead-in groove 2, ala lateralis the 3, second pitman lead-in groove 4, inboard wing 5, handle 6, drag hook main body 7, triangular pointed fixes end 8, the fixing end of " M " type
Detailed description of the invention
As shown in Figure 1, this fixed-wing tubulose drag hook mainly includes drag hook main body 6, and it is connected to the handle 5 of drag hook main body 6 one end, drag hook main body 6 is the cylindrical shape being made up of a side opening the inboard wing 4 of arc and ala lateralis 2, the upper channel of its drag hook main body 6 is the first pitman lead-in groove 3, walk with holding rod device for pitman, and surgical field of view can be increased, the passage of distal section is the second pitman lead-in groove 3, pass freely through for pitman, inboard wing 4 end is provided with a triangular pointed and fixes end 7 (being similar to the head of laminectomy retractor), can be fixed on inside articular process of lumbar vertebra, prevent drag hook from sliding；Ala lateralis 2 end is provided with " M " type and fixes end 8, can straddle on the transverse process that thoracic vertebra is thick, prevents drag hook from sliding.
