Abstract
The utility model provides an external fixation driftbolt structure for intertrochanteric fracture and comprises a drill, a bolt and at least one guide pin (1). The utility model is characterized in that the upper and the lower edge of the guide pin (1) is provided with a small incision; an external fixed nail positioning sleeve device (2) is arranged in the incision; the drill is used for drilling on bone surface of a cortical bone on the outside of a greater trochanter of a thighbone through the external fixed nail positioning sleeve device (2), and then an external fixed bolt is screwed in the drilling hole. With the structure of the utility model, a soft tissue propeller and the external sleeve device reduce damage of soft tissue due to drilling of the drill and screwing of the bolt and early functional exercise after operation and ground activity of the client can be better. The positioning and direction of the guide pin brings into correspondence with that of drilling of the drill and the screwing of the bolt, therefore, blindness of driftbolt of the external fixed nail for intertrochanteric fracture can be eliminated completely. Time consumption for operation is shortened greatly and shining of X-ray on the client is reduced.
Description
Technical field
This utility model relates to the medical apparatus and instruments for the treatment of fracture, especially about the drift bolt structure of intertrochanteric fracture external fixation.
Background technology
At present, drift bolt direction and the position to intertrochanteric fracture external fixation nail all is to be controlled according to the experience of oneself by the doctor both at home and abroad, has very big blindness.The drift bolt technology of Orthofix V-type external fixer is: earlier put two pieces of diameter 2mm guide pins by the greater trochanter of femur outside is parallel, " C " type arm X-ray confirms that the position is appropriate, below guide pin, do the little otch of 1cm again, be drilled in the boring of guide pin parallel beneath with special leading, keep corresponding collodiaphyseal angle precursor angle, parallel with guide pin again screw-in screw is pulled out guide pin.There are three problems in its method: one, and bit bore and screw threads are fashionable all to cause damage to surrounding soft tissue, thereby influences patient's postoperative early functional exercise and activity down; Its two, the distance that drill bit and guide pin keep during boring is not actual required ideal distance; Its three, because of guide pin toughness, the direction during bit bore is difficult to be consistent with guide pin all the time, will cause collodiaphyseal angle and precursor angle bigger than normal or less than normal slightly accidentally, in case boring is finished, thinks that the re-adjustment direction easily causes the nail hole loosening again.
Summary of the invention
For real drift bolt direction and the orientation problem that solves the intertrochanteric fracture outer set screw, and reduce damage to soft tissue, this utility model provides a cover complete external fixation drift bolt structure.
The technical solution of the utility model realizes in the following manner: intertrochanteric fracture external fixation drift bolt structure, comprise drill bit, screw and at least one piece of guide pin, it is characterized in that having on the lower edge on the described guide pin little otch, insert external fixation nail abutment sleeve device, drill bit to the cortical bone surface of bone boring of the greater trochanter of femur outside, screws in outer set screw by external fixation nail abutment sleeve device.
As further improvement of the utility model, be provided with the soft tissue propeller in the endoporus of external fixation nail abutment sleeve device, make it together be inserted into greater trochanter of femur outside cortical bone surface of bone along the guide pin direction, abutment sleeve location pin hole and vertical line are consistent.
The another step of the present utility model improves, and is to be provided with the outer sleeve fixation Kel's needle in described soft tissue propeller.
Of the present utility modelly further improving, is also to be provided with drill holder in the external fixation nail abutment sleeve device, and a centre bore is also arranged in it, extract soft tissue propeller 5 after, for bit bore.
This utility model is compared with prior art: soft tissue propeller and outer sleeve device have reduced because of bit bore and the fashionable damage to soft tissue of screw threads, more help patient's postoperative early functional exercise and movable down.The location of guide pin and direction are consistent with the fashionable direction of bit bore and screw threads all the time, and the blindness that this has fundamentally eliminated strand intertrochanteric fracture external fixation nail drift bolt has also shortened operating time simultaneously greatly, has reduced the irradiation of X ray to operator.

Being known by Fig. 2, is that the drill holder 7 of present embodiment cooperates sketch map with external fixation nail abutment sleeve device 2.After pulling out guide pin and soft tissue propeller 5, drill holder 7 is inserted in the external fixation nail abutment sleeve device 2.
Being known by Fig. 3, is the cutaway view of external fixation nail abutment sleeve device 2, and an end of staple abutment sleeve device 2 is provided with two locating holes 3 outside, and piercing diameter respectively is the outer sleeve fixation Kel's needle 4 of 2.5mm.
Being known by Fig. 4, is the cutaway view of soft tissue propeller 5, and a centre bore is arranged in the soft tissue propeller 5, along guide pin 1 soft tissue propeller 5 and external fixation nail abutment sleeve 2 is together inserted wherein.
Being known by Fig. 5, is the cutaway view of drill holder 7, and a centre bore 6 is also arranged in the drill holder 7, extract soft tissue propeller 5 after, for bit bore.
During work, earlier put two pieces of diameter 2.5mm guide pins 1 by the greater trochanter of femur outside is parallel, " C " type arm X-ray confirms that the guide pin position is appropriate, lower edge is done the little otch of 1cm on guide pin respectively, soft tissue propeller 5 is inserted in the external fixation nail abutment sleeve device 2, together be inserted into greater trochanter of femur outside cortical bone surface of bone along guide pin 1 direction, abutment sleeve device 2 liang of location pin hole and vertical line are consistent, pierce diameter 2.5mm Kirschner wire respectively along pin two locating holes, pull out guide pin 1 and soft tissue propeller 5, drill holder 7 is inserted in the external fixation nail abutment sleeve device 2, bit bore, take out drill holder 7, screw in outer set screw, take out external fixation nail abutment sleeve device 2 at last.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of this utility model requirement.
