Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a gynecological special tension self-adjusting inspection device. Background Art

[0002] In clinical medicine, a duckbill endoscope is generally used to examine a woman's vagina. The duckbill endoscope usually consists of two pages of expansion plates and a handle. The use of the duckbill endoscope is to first close the two pages of expansion plates, then insert them into the vagina, and then use the handle in the vagina to open the upper and lower pages of expansion plates to a certain angle, thereby pushing open the tissue structure in the vagina for medical staff to examine.

[0003] The shortcomings of the existing technology: However, in actual use, in order to expand the tissue structure in the vagina as much as possible so that the inside of the vagina can be observed, the duckbill endoscope generally inserts the expansion plate into the vagina first, and then controls the expansion plate to open to both sides, thereby causing the external tension and the internal tension to gradually increase, similar to a cone. Since the internal tension and external tension of the vagina cannot be adjusted separately when the endoscope is opened, in order to be able to expand the inside of the vagina and have a sufficient observation field of view, it is difficult to balance the internal tension and external tension of the patient's vagina, which not only makes the patient less comfortable, but also the endoscope cannot move further in the vagina, resulting in a fixed opening range and a limited observation range. For this reason, we propose a gynecological-specific self-adjusting tension inspection device. Summary of the invention

[0028] When the embodiment of the present invention is actually used, the second expansion piece 308 is inserted into the vagina, and then the first expansion piece 304 and part of the opening piece 203 are gradually inserted. At this time, the four opening pieces 203 are controlled to expand in all directions respectively. At this time, the outside of the vagina can be opened according to the individual's adaptability, and then the flexible rack 501 is pulled, and the flexible rack 501 will simultaneously drive the second gear 502 and the third gear 503 to rotate, and the second gear 502 will drive the first connecting shaft 302 to rotate, and the first connecting shaft 302 will drive the second rotating seat 303 to rotate, and the second rotating seat 303 will drive the first expansion piece 304 to rotate and expand outward. At the same time, when the third gear 503 rotates, the third gear 503 will drive the second connecting shaft 306 to rotate, and the third gear 503 will drive the second connecting shaft 306 to rotate. The second connecting shaft 306 will drive the fourth rotating seat 307 to rotate, and the fourth rotating seat 307 will drive the second expansion piece 308 to rotate and close inward, so that the second expansion piece 304 always remains parallel to the opening piece 203, and the first expansion piece 304 rotates and expands outward to expand the inside of the vagina. The expansion angle can be adjusted according to the individual's adaptability, which can reduce the discomfort of the patient during the examination, and the outside and inside of the vagina can be opened to the greatest extent to improve the observation field of view.

[0032] When the embodiment of the present invention is actually used, by rotating the turntable 207, the turntable 207 will drive the ring gear 208 to rotate, and the ring gear 208 will simultaneously drive the four first gears 206 to rotate simultaneously. At this time, the upper and lower positions of the first gears 206 can be limited by the action of the limit seat 205. When the first gear 206 rotates, it can drive the threaded rod 204 to move upward with the cooperation of the guide rod 202, and the threaded rod 204 will drive the expansion piece 203 to spread around, thereby achieving the effect of expanding multiple expansion pieces 203 outward at the same time.

[0033] like Fig. 9 As shown, as another preferred embodiment of the present invention, a slide groove 5 is provided in the expansion piece 203, the first expansion piece 304 and the second expansion piece 308, a flexible rack 501 is slidably connected in the slide groove 5, a second gear 502 is fixedly connected to the circumferential surface of the first connecting shaft 302, a third gear 503 is fixedly connected to the circumferential surface of the second connecting shaft 306, and the second gear 502 and the third gear 503 are meshed with the flexible rack 501.

[0034] When the embodiment of the present invention is actually used, by pulling the flexible rack 501 to slide in the slide groove 5, the flexible rack 501 will simultaneously drive the second gear 502 and the third gear 503 to rotate in opposite directions, thereby driving the first connecting shaft 302 and the second connecting shaft 306 to rotate, thereby achieving the effect of driving the two-stage expansion mechanism 3 to operate.

[0035] like Figure 6As shown, as another preferred embodiment of the present invention, the rear end of the flexible rack 501 is fixedly connected to the pull rope 504, the circumferential surface of the connecting tube 2 is fixedly connected to the threaded sleeve 505, the circumferential surface of the threaded sleeve 505 is threadedly connected to the traction disk 506, the end of the pull rope 504 away from the flexible rack 501 is fixedly connected to the traction disk 506, a pair of tension springs 507 are fixedly connected in the slide groove 5, and the flexible rack 501 and the rear end of the tension spring 507 are fixedly connected.

[0036] When the embodiment of the present invention is actually used, by rotating the traction disk 506 on the circumferential surface of the threaded sleeve 505, the traction disk 506 will rotate and move forward, and at the same time, rotate and pull the four pull ropes 504, and the four pull ropes 504 will pull the flexible rack 501 backward, thereby achieving the effect of driving the second gear 502 and the third gear 503 to rotate, so that the two-stage expansion mechanism 3 can operate, and at the same time, the traction disk 506 is rotated in the opposite direction, and the pulling force on the pull rope 504 can be released. Subsequently, under the action of the tension spring 507, the flexible rack 501 will be pulled forward to reset, thereby achieving the effect of controlling the reset of the two-stage expansion mechanism 3.

[0038] In actual application, the embodiment of the present invention can achieve a transition effect on the pull rope 504 under the action of the first guide wheel 508 and the second guide wheel 509 when the traction disk 506 pulls the pull rope 504, thereby reducing the friction of the pull rope 504 and improving the smoothness of the movement of the pull rope 504.

[0039] like Fig. 9 and 10 As shown, as another preferred embodiment of the present invention, the circumferential surfaces of the first connecting shaft 302 and the second connecting shaft 306 are both rotatably connected to the limiting frame 7, and the front and rear ends of the limiting frame 7 are rotatably connected to the transition wheel 701, and the transition wheel 701 is in contact with the flexible rack 501.

[0040] When the embodiment of the present invention is actually used, the transition wheel 701 rotatably connected in the limit frame 7 can always press down the flexible rack 501 that meshes with the third gear 503 of the second gear 502. When the second-stage expansion mechanism 3 is operating, the flexible rack 501 at the meshing position can be prevented from turning outward, so that the connectivity between the flexible rack 501 and the third gear 503 of the second gear 502 can always remain stable.
