Referring to fig. 1-2, the gynecological clinical dilator comprises a box body 1 and an upper cover 2, wherein the box body 1 is clamped with the upper cover 2, the box body 1 is provided with an installation cavity 3, and a rotating device 4 is arranged in the installation cavity 3;

the rotating device 4 comprises a rotating rod 5 and a fixed rod 6 which are connected through threads, the fixed rod 6 is provided with external threads, the rotating rod 5 is provided with internal threads matched with the fixed rod 6, and the fixed rod 6 is fixed with an expansion device 7; the expansion device 7 can be driven to move back and forth through the threaded rotation of the rotating rod 5 and the fixed rod 6, so that the contraction and expansion are carried out;

the rotating rod 5 penetrates through the box body 1 and is fixedly connected with a knob 14, and the upper cover 2 is provided with a clamping device 15 matched with the knob 14; the setting of latch 15 can be fixed a position knob 14 and dwang 5 to can not need long-time hand-held device in the inspection process, can liberate doctor's both hands and carry out work, because latch 15's effect makes knob 14 unable rotation. Therefore, the device is difficult to move randomly, the clamping device 15 can be pulled out when the device is used, and then the rotating rod 5 is rotated, so that the device can be adjusted.

Expansion device 7 fixedly connected with spring 16,

spring

16 and 1 inner wall fixed connection of box body, spring 16 can rotate at dress dwang 5, drive the in-process of dead lever 6 and 7 back-and-forth movements of expansion device, can make the effect of the force balanced to transfer line 17 both ends and middle part by transfer line 17 middle part, increase transfer line 17's stability, prevent that transfer line 17 is crooked, and when dwang 5 and dead lever 6 rotate to the maximum position, spring 16 gives 6 one power to dwang 5 of dead lever constantly, make dwang 5 cup joint together with dead lever 6 is stable, prevent to break away from each other.

The expansion device 7 comprises a transmission rod 17, the transmission rod 17 is fixedly connected with a fixed block 19, the fixed block 19 is fixedly connected with the fixed rod 6, two ends of the transmission rod 17 are respectively and fixedly connected with a first connecting rod 8 and a second connecting rod 10, the box body 1 is provided with a through hole 18 matched with the first connecting rod 8 and the second connecting rod 10, the through hole 18 can facilitate the front and back movement of the first connecting rod 8 and the second connecting rod 10 and prevent the transmission rod 17 from being separated from the device, the stability of the device is improved, the first connecting rod 8 is fixedly connected with an arc-shaped block 9, the arc-shaped block 9 is fixedly connected with the second connecting rod 10, the arc-shaped block 9 is fixedly connected with a first expansion plate 11, the rotating rod 5 rotates to drive the fixed rod 6 to move back and forth on the rotating rod 5, so as to drive the transmission rod 17, the first connecting rod, or to retract it back to its original position.

The arc-shaped block 9 is provided with an LED lamp strip, and the LED lamp strip can illuminate in the using process, so that the doctor can conveniently check the LED lamp strip.

The box body 1 is fixedly connected with a second expansion plate 12 matched with the first expansion plate 11, the first expansion plate 11 is matched with the second expansion plate 12 to expand a patient, and the rotating rod 5 is rotated to drive the first connecting rod 8 and the second connecting rod 10 to extend forwards so that the first expansion plate 11 is far away from the second expansion plate 12 to expand; the reverse rotation of the rotating rod 5 drives the first connecting rod 8 and the second connecting rod 10 to contract backwards, so that the first expansion plate 11 is close to the second expansion plate 12, and the contraction is performed.

First expansion board 11 all is equipped with observation hole 13 with second expansion board 12, and the setting up of observation hole 13 reduces the sheltering from area of first expansion board 11 and second expansion board 12 to the wound, the inspection of being convenient for.

Clamping device 15 rotates with upper cover 2 through bearing 20 to be connected, bearing 20 fixedly connected with shell fragment 21, shell fragment 21 is equipped with the draw-in groove 22 with 14 looks adaptations of knob, shell fragment 21 passes through draw-in

groove

22 and 14 activity joint of knob, clamping device 15's setting can make draw-in

groove

22 and 14 joints of knob, thereby can be when the fixed first expansion board 11 of needs, can make it fixed, when draw-in

groove

22 and 14 joints of knob, shell fragment 21 produces elastic deformation, thereby give a outside power of knob, thereby drive knob 14 and dwang 5 and produce less displacement, make the friction between dwang 5 and the 6 screw threads of dead lever increase, thereby increase the frictional force between dwang 5 and dead lever 6, thereby prevent that dwang 5 from skidding in the expansion process.

The working principle is as follows: when the device is used, a worker presses the elastic sheet 21 by hand to separate the elastic sheet 21 from the knob 14, then lifts the elastic sheet 21 upwards to completely separate the elastic sheet 21 from the knob 14, then rotates the knob 14 to adjust the device, rotates the knob 14 to drive the rotating rod 5 to rotate, shortens the sleeving length of the rotating rod 5 and the fixing rod 6, and extends the first connecting rod 8 and the second connecting rod 10 forwards to enable the first expansion plate 11 to be far away from the second expansion plate 12 so as to expand; the reverse rotation dwang 5 drives the first connecting rod 8 and the second connecting rod 10 to contract backwards, so that the first expansion plate 11 is close to the second expansion plate 12, thereby contracting, when expanding to a proper position, pressing the elastic sheet 21 to be clamped with the knob 14, and further fixing the device.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
