Abstract
The utility model relates to an iliac steel plate screw inner fixing device for combined lumb-saero-iliac fixation. The device consists of a trapezoid steel plate, an iliosacral screw, U-shaped grooves and a nut, wherein the trapezoid steel plate consists of a left wing, a right wing and a steel plate intermediate part, an obtuse angle is formed between the left wing and the steel plate intermediate part and between the right wing and the steel plate intermediate part; 2 to 3 steel plate holes are respectively formed on the left wing and the right wing; the iliosacral screw can be implanted from the rear side of the ala of ilium, so that the iliosacral screw can pass through the ala of ilium and enter the front sacrum; two U-shaped grooves are formed in the middle of the steel plate intermediate part for accommodating a titanium bar; an internal thread is arranged above the U-shaped grooves, and is jogged with an outer thread of the nut, and the titanium bar extending from the lumbosacral vertebrae is fixed when the nut is locked to achieve the aim of lumb-saero-iliac steady connection. According to the iliac steel plate screw inner fixing device, the implanting direction of a traditional iliosacral screw is adjusted by a smart structural design, so that the screw can be implanted more simply and more safely, and performs steady connection with the above lumbosacral fixation by virtue of a special structure to achieve the aim of lumb-saero-iliac fixation.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of fixed ilium steel plate screw of waist sacroiliac symphysis inner fixing device that is applicable to.
Background technology
The long segment of spinal column is fixing need to extend to rumpbone even ilium to obtain the stability of fixed-segment from lumbar vertebra with fixed-segment usually; Yet mostly present spinal internal fixation system is nail-stick system; Can the afterbody of pedicle screw be connected fixingly through the titanium rod for lumbar vertebra and rumpbone fixing, with being connected and fixing then difficulty comparatively of ilium, the implantation that traditional fixed system requirement ilium is followed closely need be implanted by posterior superior iliac spine; Advancing to follow closely direction need parallel along ala of ilium direction and top; Direction is wayward, and operating difficulties, screw very easily penetrate the ilium wall and cause internal fixation failure even damage pelvic tissue.Therefore study a kind of easy and simple to handlely, the fixed ilium fixture of waist sacrum ilium long segment is significant in safe in utilization being applicable to.
Summary of the invention
The purpose of this utility model is to provide a kind of fixed ilium steel plate screw of waist sacroiliac symphysis inner fixing device that is applicable to.
This utility model proposes is applicable to the fixed ilium steel plate screw of waist sacroiliac symphysis inner fixing device, is made up of trapezoidal steel plate 1, sacroiliac screw 2, U-lag 3 and nut 4, and trapezoidal steel plate 1 is made up of left wing 5, right flank 6 and steel plate pars intermedia 7; Left wing 5 is connected through steel plate pars intermedia 7 with right flank 6; Steel plate pars intermedia 7 is provided with U-lag 3, and titanium rod 8 inserts in the U-lag 3, and there is female thread the top of U-lag 3; Chimeric each other with the external screw thread of nut 4, titanium rod 8 is fixed in the U-lag 3 through nut 4; Have steel plate hole on left wing 5 and the right flank 6, sacroiliac screw 2 passes this steel plate hole.
In this utility model, left wing 5 and right flank 6 and steel plate pars intermedia 7 junctions are in obtuse angle.
In this utility model, have 2-3 steel plate hole on left wing 5 and the right flank 6.
In this utility model, the internal diameter of two U-lags 3 is two kinds of 5.5mm and 6.5mm, and the spacing of two U-lags 3 has 35mm, 45mm or three kinds of specifications of 55mm.
The beneficial effect of this utility model is: this utility model be mainly used in the spinal column long segment fixing in; When needing simultaneously waist sacrum ilium fixedly, its major advantage has provided a kind of inner fixing device easy and simple to handle, safe in utilization, and this device passes through structural design cleverly; Adjusted the implantation direction of traditional sacroiliac screw; Make the implantation of screw simple more, safety, and fixedly stablize with the waist sacrum of top through particular structural and to be connected, reached fixed purpose of waist sacrum ilium while; This utility model is novel, is convenient to popularization, practical.
