Description

Technical Field

[0001] The invention relates to the technical field of gynecological examination, in particular to a vaginal dilating device used for gynecological examination. Background Art

[0002] Gynecology is a diagnostic and treatment subject in medical institutions. Gynecology is a branch of obstetrics and gynecology. It is a professional department that diagnoses and treats female gynecological diseases. When examining gynecological patients, gynecologists need to use gynecological dilators to open the patient's vagina to facilitate sampling operations by medical staff.

[0003] The front end of the existing vaginal dilator is often duck-billed. When it is inserted into the lower body of a gynecological patient, the duck-billed inspection mechanism causes excessive pain and discomfort to the gynecological patient during the inspection. In addition, the duck-billed vaginal dilator cannot be adjusted quickly and conveniently when opening, which causes the side opening to be too large, further increasing the patient's discomfort during the inspection. When the opening is too small, medical staff cannot quickly and accurately take samples and inspect, which affects the accuracy of the patient's condition and the quality of subsequent treatment. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a vaginal dilation device for gynecological examination, which solves the problems raised in the background technology.

[0010] By adopting the above technical solution, the movable plate is rotated and installed inside the installation groove by rotating the rod, thereby ensuring that the movable plate drives the hollow sleeve to rotate accordingly and drives the sampling cotton swab to perform inclined sampling.

[0011] As a preferred embodiment of the present invention, a connecting rod is vertically penetrated and slidably inserted into the middle end of the movable plate, and a hollow sleeve is fixedly installed on the top surface of the connecting rod.

[0012] By adopting the above technical solution, the medical sampling cotton swab can be fixed by the structural effect of the hollow sleeve.

[0013] As a preferred embodiment of the present invention, a movable groove is provided inside the middle end of the movable plate, and the connecting rod penetrates and is slidably installed inside the movable groove.

[0014] By adopting the above technical solution, the movable groove guides and slides the connecting rod, thereby ensuring that the connecting rod will not drive the hollow sleeve to move arbitrarily and affect the normal sampling and detection.

[0015] As a preferred embodiment of the present invention, the diameter of the hollow sleeve is larger than the inner diameter of the movable groove, and the hollow sleeve is located above the outer side of the movable groove.

[0016] By adopting the above technical solution, a hollow sleeve with a diameter larger than the inner diameter of the movable groove is provided, so that when medical staff pull the connecting rod to adjust the position of the sampling cotton swab, the hollow sleeve will not be arbitrarily moved out of the movable groove and the movable plate to affect subsequent reuse.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The models of electrical appliances provided in the present invention are only for reference, and different models of electrical appliances with the same functions can be replaced according to actual usage.

[0028] See also Figure 1-3 The present invention provides a technical solution: a connecting rod 33 is vertically penetrated and slidably inserted into the middle end of the movable plate 32, and a hollow sleeve 34 is fixedly installed on the top surface of the connecting rod 33, so as to facilitate the insertion of the wooden handle end of the medical sampling cotton swab for detection and fixation.

[0029] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), both ends of the side of the hollow transmission cylinder 11 are side openings, and the shape of the side openings is V-shaped, a connecting plate 2 is fixedly installed on the inner middle end surface of the hollow transmission cylinder 11, a transmission rod 21 is vertically fixedly installed on the bottom middle end, a hand-pull plate 22 is fixedly installed on the bottom surface of the transmission rod 21, the transmission rod 21 is installed through the inside of the expansion cylinder 1, and the bottom of the transmission rod 21 extends to the outside of the expansion cylinder 1, and the hand-pull plate 22 is movably installed at the lower outside of the expansion cylinder 1.

[0030] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a movable groove 4 is opened inside the middle end of the movable plate 32, and the connecting rod 33 is slidably installed inside the movable groove 4, the diameter of the hollow sleeve 34 is larger than the inner diameter of the movable groove 4, and the hollow sleeve 34 is located above the outer side of the movable groove 4.

[0031] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), a mounting groove 3 is opened inside the side of the hand-pull plate 22, and a movable plate 32 is rotatably installed inside the mounting groove 3. Rotating rods 31 are rotatably installed inside both ends of the side of the mounting groove 3 through bearings, and the side of the rotating rod 31 is fixedly connected to the outer side of the mounting groove 3.

[0032] During operation, after the bottom of the medical cotton swab required for inspection and sampling is inserted into the hollow sleeve 34, the gynecological patient is allowed to lie flat on the surface of the inspection table, and the expansion tube 1 is slowly pushed into the patient's vulva. The examining physician holds the hand-pull plate 22 and pulls it outward, so that under the transmission action of the transmission rod 21, the connecting plate 2 and the hollow transmission tube 11 are driven to move outward synchronously inside the expansion tube 1, so that the hollow transmission tube 11 can push the shells at both ends of the top side opening of the expansion tube 1 while moving, so that after the two ends of the side edges of the expansion tube 1 are squeezed and deformed, the two ends of the side edges of the expansion tube 1 are stretched outward to expand the vulva of the gynecological patient. After expanding to a diameter that is convenient for the physician to inspect and sample, the physician pushes the connecting rod 33 to drive the hollow sleeve 34 and the medical sampling cotton swab inserted therein to penetrate deep into the gynecological patient. After the inside of the expanded vagina is expanded, the connecting rod 33 is pushed to drive the movable plate 32 to rotate in the mounting groove 3 inside the hand-pull plate 22, so that the connecting rod 33 and the medical sampling cotton swab are tilted until the outer side of the medical sampling cotton swab is attached to the position of the inner wall of the vagina of the gynecological patient to be tested and sampled, and after the mucus on its surface is smeared, the connecting rod 33 is pulled outward to drive the medical sampling cotton swab to move out of the patient's body, and then the hand-pull plate 22 is pushed inward, so that the hollow transmission sleeve moves synchronously and loses the resistance force on the side shell of the expansion tube 1, thereby causing the expansion tube 1 to restore its shape and lose the expansion effect on the gynecological patient's vulva, and then the expansion tube 1 is slowly pulled out of the gynecological patient's body, and then the mucus picked up by the medical sampling cotton swab is tested, so as to judge and treat the gynecological patient's condition.
