Description
Technical field
The present invention relates to a kind of utensil assisting accurately to implant sacroiliac joint internal fixation screw in the operation of orthopaedics sacroiliac fracture-dislocation reduction fixation, belong to bone surgery utensil technical field.
Background technology
At present, the sacroiliac fracture-dislocation that the contour Energy Damage of traffic accident wound causes is more and more common, and femoral neck cannulated screw internal fixtion is the good method of therapeutic effect.In femoral neck cannulated screw internal fixation operation, need lag screw lateral surface after ala of ilium to insert and enter sacrum 1 vertebral body through sacroiliac joint, conventional method first implants guide pin to perceive entrance position again and determine that whether inserting needle direction is correct, therefore there is the shortcomings such as fluoroscopy during operation number of times is more, guide pin method need repeatedly adjust, medical personnel's x-ray radiation is more in operation, bring very large inconvenience to the operation of operation.In operation, pedicle screw position is wanted accurately, otherwise enters canalis spinalis and can damage cauda equina nerve, or penetrates the empty injured nerve root of the 1st sacrum.Current clinician can only rely on experience and repeatedly have an X-rayed and perform the operation, this just makes sacroiliac fracture-dislocation reduction fixation perform the operation very large difficulty, not only therefore extend operating time, the more important thing is and can have influence on surgical effect, be unfavorable for the rehabilitation of patient.Up to the present this situation does not obtain basic change, and become the principal element that the operation of restriction orthopaedics sacroiliac fracture-dislocation reduction fixation obtains ideal effect, necessary taking measures is solved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of femoral neck cannulated screw three-dimensional locator, adopt this three-dimensional locator can determine the position of screw in vitro, simplify operation process, operating time is shorter, fix sacroiliac joint for Wicresoft and provide new method, ensure that operation reaches desirable effect, meanwhile, in art, medical personnel do not need to accept radiation.
The technical scheme solved the problems of the technologies described above is:
A kind of femoral neck cannulated screw three-dimensional locator, it comprises crosspointer Fluoroscopy location part and screw targeting part, crosspointer Fluoroscopy location part is made up of two positioning needles and fixed bar, two positioning needles are parallel, the two ends of two positioning needles are connected to fixed bar, the upper end of fixed bar is connected to the receptor both sides of C-arm X-ray machine by set bolt, the plane that two positioning needles are formed in the below of receptor, with receptor plane orthogonal; Screw targeting part is an inverted U-shaped framework, and the body of rod of inverted U-shaped framework both sides has relative cannulated sleeve and guide pinhole respectively, and the axis of cannulated sleeve and guide pinhole point-blank.
Above-mentioned femoral neck cannulated screw three-dimensional locator, there is screw the upper end of the both sides fixed bar of described crosspointer Fluoroscopy location part respectively, and the screw of both sides fixed bar is equal with the distance of both sides positioning needle, installs spotlight respectively on fixed bar top, both sides.
Above-mentioned femoral neck cannulated screw three-dimensional locator, is inserted with guide pin in the guide pinhole of described screw targeting part, and guide pin and guide pinhole are for being slidably matched.
The invention has the beneficial effects as follows:
Crosspointer Fluoroscopy location part is arranged on below the receptor of C-arm X-ray machine by the present invention, two positioning needles form superimposed image at the pelvis area of patient, the receptor position of adjustment C-arm X-ray machine, the implantation position can determining guide pin is intersected by two superimposed images, insert guide pin by the guide pinhole of screw targeting part again, finally determine the implantation position of screw.Structure of the present invention is simple, be skillfully constructed, can determine the position of screw in vitro, accurate positioning, operation is simple, simplify operation process, operating time is shorter, greatly reduces operating time, fixes sacroiliac joint provide new method for Wicresoft, ensure that operation reaches desirable effect, meanwhile, in art, medical personnel do not need to accept radiation, and applicable basic hospital and various big hospital carry out applying and promoting.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1.
In figure, labelling is as follows: receptor 1, positioning needle 2, fixed bar 3, set bolt 4, inverted U-shaped framework 5, cannulated sleeve 6, guide pinhole 7, guide pin 8, spotlight 9.
Detailed description of the invention
The present invention includes crosspointer Fluoroscopy location part and screw targeting part.
Show in figure, crosspointer Fluoroscopy location part is made up of two positioning needles 2 and fixed bar 3.Two positioning needles 2 are parallel, the two ends of two positioning needles 2 are connected and fixed bar 3 respectively, there is screw the upper end of both sides fixed bar 3 respectively, the screw of both sides fixed bar 3 is equal with the distance of both sides positioning needle 2, the upper end of two fixed bars 3 is connected to receptor 1 both sides of C-arm X-ray machine by set bolt 4, the plane that two positioning needles 2 are formed in the below of receptor 1, with receptor 1 plane orthogonal.
Show in figure, on both sides fixed bar 3 top, spotlight 9 be installed respectively, light-illuminating positioning needle 2, below the receptor 1 that the shadow of positioning needle 2 can be projected C-arm X-ray machine clinostatism patient with it.
Show in figure, screw targeting part is an inverted U-shaped framework 5, the body of rod of inverted U-shaped framework 5 both sides has relative cannulated sleeve 6 and guide pinhole 7 respectively, and cannulated sleeve 6 is equal with the distance of inverted U-shaped framework 5 upper end with guide pinhole 7, and the axis of cannulated sleeve 6 and guide pinhole 7 point-blank.In guide pinhole 7, be inserted with guide pin 8, guide pin 8 and guide pinhole 7 are for being slidably matched.
Using method of the present invention is as follows:
Patient lies supine or prostrate on roentgenolucent operating-table, is installed on the crosspointer Fluoroscopy location part of three-dimensional locator on the receptor 1 of C-arm X-ray machine, makes it vertical with receptor 1.
First, choose the entrance position image of perspective standard, make two positioning needles 2 form a mcakle.Adjustment C-arm position, in making the image projecting of mcakle in pelvic region and performing the operation, the true guide pin implantation position envisioned is consistent, and mcakle is positioned in the middle part of sacrum one lateral mass, in sacrum one vertebral body first three/mono-.Open spotlight, the overlapping shadow of visible two positioning needles appears on patient skin, with the bow pen line that labelling shadow is formed on skin.
Afterwards, choose the outlet position image of perspective standard, make two positioning needles 2 form a mcakle.Adjustment C-arm position, makes the image projecting of mcakle in pelvic region consistent with the true guide pin implantation position envisioned in operation, and between sacrum one vertebral foramen and ala sacralis upper limb, can not be on the upper side or on the lower side.Open spotlight, the overlapping shadow of visible two positioning needles appears on patient skin, with the bow pen line that labelling shadow is formed on skin.The line that this line and entrance position image are formed crosses two intersection points, and Ipsilateral intersection point is into pin mark, and strong top-cross point is and fictionalizes pin mark.
By cannulated sleeve 6 one end of the inverted U-shaped framework 5 of screw targeting part with enter pin mark and contact, guide pinhole 7 one end with fictionalize pin mark and contact, guide pin 8 is pierced pelvis along cannulated sleeve 6, guide pin 8 perceives entrance position through C-arm X-ray machine, after position is satisfied, depth measurement, being screwed into is the screw of suitable length, ray inspection screw position, gets final product complete operation again.
