Detailed description of the invention:
Below in conjunction with accompanying drawing, this utility model is described in further detail:
As shown in Figure 1, 2, horizontal skull support (1) and horizontal skull support (2) end are respectively arranged with 5 " screw holes ", horizontal skull support (1) and horizontal skull support (2) are fixed in patient's skull by medical titanium screw 17.Horizontal skull support (1) and horizontal skull support (2) are respectively arranged with arc-shaped slide rail (3) and arc-shaped slide rail (4), arc-shaped slide rail is substantially consistent with the side, face of people, front appearance radian, arc-shaped slide rail (3) and arc-shaped slide rail (4) are totally continuous, and cover facial side, 180 degree, front scope.The mid portion of horizontal skull support (1) is provided with key way 5, and the mid portion of horizontal skull support (2) is provided with key 6.Key 6 can insert in key way 5 completely, and insert the width between the horizontal skull support (1) of degree of depth adjustment of key way 6 and (2) by adjustment key 5, adapt to the width of different patient's skull, and by key way key retaining screw 7, horizontal skull support (1) and horizontal skull support (2) can be fixed together in this position.
Described vertical distraction support has two kinds of specifications: vertical distraction support 9 and vertical distraction support 12.
As shown in Figure 3, vertical distraction support 9 can slide along the arc-shaped slide rail (3) on horizontal skull support (1) and horizontal skull support (2) and arc-shaped slide rail (4), and is fixed on a certain position by vertical distraction support retaining screw 10.This function can meet when an only needs installation vertical distraction support, the traction of diverse location within the scope of 180 degree in the presence of.
As shown in Figure 4, vertical distraction support 12: when key 6 part of horizontal skull support (2) extracts certain length out from key way 5 part of horizontal stand (1), key 6 part of horizontal skull support (2) will come out.Key 6 segment thickness because of horizontal skull support (2) is less than horizontal skull support (2), so 9, the vertical distraction support being applicable to horizontal skull support (1) and (2) is not suitable for the key 6 of horizontal skull support (2).As just needed to install vertical distraction support in this part, then vertical distraction support 9 is unavailable.For this reason, the present invention has designed and produced the vertical distraction support 12 of the key 6 being applicable to horizontal skull support (2).The bayonet socket of vertical distraction support 12 is less than vertical distraction support 9.
As shown in Figure 5, vertical distraction support 9 and vertical distraction support 12 one side are provided with the multiple square holes fitting in through traction screw 13, such one side can ensure that traction screw 13 can be put along adjusted position any on same vertical distraction support 9 or vertical distraction support 12 above-below direction, realize the face of same position differing heights in the presence of bone section level to traction.Vertical distraction support 9 and 12 another side is provided with multiple circular hole side by side, and circular hole spacing is 1-3mm, and rotation external member 15 is fixed on desired location by circular hole by the retaining screw 14 rotating external member.Rotate the lead that external member 15 can limit traction screw 13, the different angles traction of same position, vertical direction in face of can realizing like this.Horizontally tracting support 16 is arranged on vertical distraction support, and horizontally tracting support 16 is provided with the multiple square holes fitting in through traction screw 13, by installing traction screw 13 in the both sides of horizontal stand 16, can realize the dead ahead traction of bilateral.
As shown in Figure 1, 2, be the use of the wider patient of skull.As required key 6 part from key way 5 can be extracted out, to reach the demand of applicable patient's skull width.As just needed to go out to install vertical distraction support at key 6, then the vertical distraction support 12 mated with key 6 is installed.The traction of other positions and angle is with above four.
Embodiment 1: is as shown in Figure 6 the traction of one-sided dead ahead.Horizontal skull support (1) and horizontal skull support (2) are fixed on the skull of patient by the skull staple 17 of horizontal skull support both sides, horizontal skull support (1), 1 vertical distraction support 9 is installed, vertical distraction support longitudinal arrangement has a row can pass the square hole of traction screw 13, and traction screw 13 is contained in middle square hole, traction nail 20 one end is fixed on the lateral surface of upper jaw bone section on the left of patient, traction nail 20 other end by traction fiber 19 from the traction screw 13 be connected between jaw vertical distraction support 9, by the afterburning screw 18 of the traction screw that turns clockwise, traction screw 13 will affect traction fiber 19, by fracture of maxillary block on the left of patient to dead ahead traction to desired location, when the afterburning screw 18 of the traction screw that turns clockwise, traction screw 13 will affect traction fiber 19, thus traction jaw bones section is to desired location, often rotate 1 week afterburning screw 18 of traction screw, traction fiber 19 will affect bone block to move 0.5mm.General every day draws twice, each 0.5mm, the morning 1 time, afternoon 1 time.The one-sided dead ahead traction of maxillofacial bone can be realized.Because vertical distraction support 9 position is adjustable, so, can draw in the optional position of dead ahead.
Embodiment 2: as shown in Figure 7, is the traction of bilateral dead ahead, on the basis of embodiment 1,1 horizontally tracting support 12 is installed by vertical distraction support 9.By the hole of 2 traction screws 13 through suitable location on horizontally tracting support 12, by traction fiber 19, traction screw 13 is connected with traction nail 20, the afterburning screw 18 of the traction screw that turns clockwise, the bilateral dead ahead traction of maxillofacial bone can be realized.
Embodiment 3: is as shown in Figure 8 the traction angle of same position in dead ahead, side 180 scope.Rotate external member 15 and be fixed on desired position on vertical distraction support 9 by rotating external member retaining screw 14, and adjustment rotates the angle of external member 15, to meet required traction angle.Traction screw 13, through the hole rotated in external member 15, is connected with traction nail 20 by traction fiber 19 by traction screw 13, and the afterburning screw 18 of the traction screw that turns clockwise, can realize the traction angle of maxillofacial bone same position in dead ahead, side 180 scope.Because vertical distraction support 9 position is adjustable, so, can draw in the optional position of dead ahead, side.If desired, multiple vertical distraction support 9 and (or) multiple rotation external member retaining screw 14 also can be installed and rotate external member 15, drawing simultaneously.
Embodiment 4: is as shown in Figure 9 the traction of one-sided side.Above (as left side needs side to draw, be then arranged on horizontal skull support (1) horizontal skull support (1) or (2); Otherwise, be arranged on horizontal skull support (2)) and one or more vertical distraction supports 9 are installed.By one or more traction screws 13 through the hole of suitable location on vertical distraction support 9, by traction fiber 19, traction screw 13 is connected with traction nail 20, the afterburning screw 18 of the traction screw that turns clockwise, the one-sided side traction of maxillofacial bone can be realized.Because vertical distraction support 9 position is adjustable, so, can draw in the optional position of side.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when the method and technology contents that can utilize above-mentioned announcement are made a little change or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
