This rat is fixed, and last hinge rear end is provided with the disk that upwards arches upward to front curve in the vaginal speculum of throwing light on, and said battery is button cell and is installed on this disk that said on and off switch is the micro power switch and also is installed on this disk.
This rat is fixed in the vaginal speculum of throwing light on, and the relative tract that forms with the recess of lower jaw in the place of arching upward of said upward hinge is along becoming big gradually by the direction behind the forward direction.
This rat is fixed from throwing light in the vaginal speculum, and the distance between two described bearing pin hinged places is greater than last expanding plate rear end, the width of expanding plate rear end down.
This rat is fixed in the vaginal speculum of throwing light on, and the width of last expanding plate rear end equates with the width of following expanding plate rear end; Distance between two described bearing pin hinged places is not less than 2 times of width of expanding plate rear end/following expanding plate rear end.The rear end that guarantees upper and lower hinge formation tract obviously increases, and is convenient to the interior operation of tract of operating theater instruments.
This rat is fixed in the vaginal speculum of throwing light on, and the described rope of tying up is from the moulding rope of tying up.Saidly constitute by crust metal-cored and that be coated on metal-cored from the moulding rope of tying up.Face upward the rat hindlimb of stretching the position in the time of being wrapped in operation technique, avoid specula to skid off from intravaginal.
The beneficial effect of this utility model is: it can observed rat vagina, cervix uteri and uterine cavity and during operation technique; The expansion rat vagina and the established tract of fixing, throw light on; And make obvious expansion the in tract rear portion be convenient to the operating theater instruments operation, and simple, convenient, good stability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is done further explanation:
Fig. 1 is the front view of this utility model embodiment;
Fig. 2 is the vertical view of this utility model embodiment;
Fig. 3 is the left view of this utility model embodiment;
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.
