Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:
Fig. 1 is the front view of the embodiment of the invention;
Fig. 2 is the vertical view of the embodiment of the invention;
Fig. 3 is the left view of the embodiment of the invention;
Among the figure: hinge on 1, main leaf on 11, expanding plate on 12,13 upper left plates, 14 upper right plates, 15 spacers; 16 positioning tooths, 2 lower jaws, 21 times main leaves, 22 times expanding plates, 23 left second line of a couplet contact pin, 24 bottom right plates; 3LED lamp sheet, 4 disks, 5 micro power switches, 6 tie up rope, 7 button cells.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, this rat is fixed mainly to comprise hinge 1, lower jaw 2 from the vaginal speculum of throwing light on.
Last hinge 1 comprises main leaf 11, goes up expanding plate 12, and last main leaf 11 middle parts are bent upwards arches upward, and last expanding plate 12 is connected in arch upward the also extension forward of the place ahead of highest point of main leaf 11.
Last hinge 1 is equipped with downward upper left plate 13, upper right plate 14 in the both sides at the place of arching upward.Lower jaw 2 is equipped with left second line of a couplet contact pin 23, bottom right plate 24 upwards in the both sides of recess.Upper left plate 13 is hinged with left second line of a couplet contact pin 23 bearing pins; 14 of bottom right connections are hinged with bottom right plate 24 bearing pins; And two bearing pin coaxial lines.During use, last hinge 1, lower jaw 2 rotate around described bearing pin, fully expand rat vagina.The bearing pin connection place of upper and lower hinge is arranged on both sides, has enlarged to observe the exposure visual field of rat cervix uteri, uterine cavity, and has not influenced operation technique.
The recess of the place of arching upward of last hinge 1 and lower jaw 2 forms one relatively and is used to observe and the tract of operation technique, and this tract has been avoided the limited space probability of partial operation along being become gradually greatly by the direction behind the forward direction.
In addition, this rat is fixed in the vaginal speculum of throwing light on, and the width of the expanding plate rear end of last hinge equates with the width of the expanding plate rear end of lower jaw; Distance between two described bearing pin hinged places is not less than 2 times of width of expanding plate rear end of the expanding plate rear end/lower jaw of hinge.The rear end of lower jaw formation tract obviously increases in the assurance, is convenient to the interior operation of tract of operating theater instruments.
At least one side in last hinge 1 rear end is provided with downward spacer 15, and spacer 15 is provided with the positioning tooth 16 of clamping lower jaw 2 back edges.Positioning tooth 16 is stuck on the lower jaw, can fix the opening and closing angle of upper and lower hinge.Positioning tooth 16 on the spacer is provided with a plurality of, and a plurality of positioning tooth 16 arranges along the vertical direction continuously, convenient so upper and lower hinge opening angle is adjusted, adjust and the fixing purpose of local field of view to reach, and also simple to operate.
Last expanding plate 12 front ends below is installed with illuminating lamp, and this illuminating lamp is a LED lamp sheet 3.Last hinge rear end is provided with the disk 4 that upwards arches upward to front curve, on this disk 4, is installed with micro power switch 5, button cell 7, and described LED lamp sheet 3 is connected into lighting circuit with this button cell 7 and a micro power switch 5.During use, the operator is through micro power switch 5 control LED lamp sheets 3, and adequate illumination rat vagina, cervix uteri have been avoided rat vagina is not only narrow but also the bathozone is come experimental observation and operation easier.
