Although they have a simple structure and can be used flexibly, medical staff need to manually press the dilator to expand it during use. It is difficult to maintain the dilator force with this examination method. After expansion, medical staff need to insert a cotton swab into the interior through the observation port for sampling. At this time, both hands are required to use it, and the observation port is small and easily blocked by the hand, which increases the difficulty of sampling.

[0026] The expansion mechanism 2 includes a first electric push rod 202, which is fixedly installed on the upper part of the handle 1. A shell 201 is fixedly installed on both sides of the upper part of the handle 1. A pushing frame 203 is slidably provided on the upper part of the handle 1.

[0027] By adopting the above technical solution, the upper expansion plate 102 can be rotated and expanded under the drive of the first electric push rod 202, thereby replacing manual expansion and making the force application more stable. At the same time, four control buttons 103 are set on one side of the handle 1, which are control buttons No. 1, No. 2, No. 3, and No. 4 from top to bottom.

[0029] By adopting the above technical solution, the clamping mechanism 5 can be driven to move, thereby facilitating sampling, and at the same time, the positions of other equipment can be adjusted to facilitate observation inside the body.

[0030] The mounting mechanism 4 comprises a first mounting plate 401, the middle of the top end of the first mounting plate 401 is fixedly mounted on the bottom end of the driving block 402, a camera 403 is fixedly mounted on one side of the top end of the first mounting plate 401, two symmetrically distributed lighting lamps 404 are fixedly mounted on one side of the camera 403, a display 405 used in conjunction with the camera 403 is fixedly mounted on one side of the upper part of the handle 1, a double-headed screw 406 is rotatably mounted on the middle part of the first mounting plate 401, a second bevel gear 411 is fixedly mounted on the middle part of the double-headed screw 406, two symmetrically distributed first screws 408 are rotatably mounted on the middle part of the first mounting plate 401, and the two first screws 408 are symmetrically mounted on the opposite sides of the first mounting plate 401. A first bevel gear 410 is fixedly installed on the opposite side, and the two first bevel gears 410 are meshed with the second bevel gear 411. Four evenly distributed limit blocks 407 are slidably provided at the lower part of the first mounting plate 401. One side of the four limit blocks 407 are respectively threadedly installed on the outer surfaces of the first screw 408 and the double-headed screw 406. A first motor 412 is fixedly installed on one side of the first mounting plate 401. One end of the double-headed screw 406 passes through the first mounting plate 401 and is fixedly installed on the driving end of the first motor 412. A second mounting plate 502 is provided at the lower part of the first mounting plate 401, and the top end of the second mounting plate 502 is in contact with the lower surface of the first mounting plate 401.

[0031] By adopting the above technical solution, the clamping mechanism 5 can be easily installed. When sampling is required, the clamping mechanism 5 can be installed at the bottom of the first mounting plate 401. When it is not needed, it can be removed, thereby increasing the distance between the upper expansion plate 102 and the lower expansion plate 101, thereby facilitating medical staff to perform other operations. At the same time, with the installation of the camera 403 and the display 405, the staff can observe the situation inside the body more conveniently and clearly.

[0032] The clamping mechanism 5 includes a fixed frame 501, the top of which is fixedly mounted on the bottom of the second mounting plate 502, and two clamping frames 503 that cooperate with each other are rotatably mounted on the lower part of the fixed frame 501, a third electric push rod 506 is movably mounted on one side of the upper part of one of the clamping frames 503, and the driving end of the third electric push rod 506 is movably mounted on the upper part of the other clamping frame 503, two symmetrically distributed driving rods 507 are movably mounted on the upper part of one of the clamping frames 503, and the other ends of the two driving rods 507 are movably mounted on one end of the other clamping frame 503, and a plurality of electric rollers 504 that cooperate with each other are rotatably mounted on the opposite sides of the two clamping frames 503, and a controller 505 is fixedly mounted on the lower surface of the middle part of the fixed frame 501.

[0033] By adopting the above technical solution, a sterile cotton swab for sampling can be clamped, and the clamped sterile cotton swab can be driven to rotate slowly by the cooperation between the electric roller 504 and the controller 505, so as to perform sampling.

[0034] Two symmetrically distributed slide grooves 204 are provided on the upper part of the handle 1 , and both sides of the push frame 203 are slidably clamped in the slide grooves 204 .

[0035] By adopting the above technical solution, under the limit of the slide groove 204, it can be ensured that the pushing frame 203 is more stable when it is driven by the first electric push rod 202 to move up and down.

[0036] A protective cover 307 is fixedly mounted on the bottom end of the fixing plate 301 .

[0037] By adopting the above technical solution, the telescopic mechanism 3 can be shielded and protected when the protective cover 307 is installed, thereby ensuring the stable operation of the telescopic mechanism 3.

[0038] A slot 308 is formed in the middle of the protection cover 307 , and the first mounting plate 401 is slidably mounted in the middle of the slot 308 .

[0039] By adopting the above technical solution, the lower clamping mechanism 5 can be easily installed under the opening of the groove body 308, and at the same time, the first mounting plate 401 can be more stable when moving under the limitation of the groove body 308.

[0040] Four evenly distributed limiting grooves 409 are formed in the middle of the first mounting plate 401 , and the lower parts of the four limiting blocks 407 are slidably clamped in the limiting grooves 409 .

[0041] By adopting the above technical solution, under the limitation of the limiting groove 409, when the double-headed screw 406 and the first screw 408 rotate, the four limiting blocks 407 can be driven to move relative to or away from each other, and will not rotate with the double-headed screw 406 and the first screw 408.

[0042] Four evenly distributed slots 413 are formed on the outer side of the second mounting plate 502 , and one side of the four limit blocks 407 are slidably locked in the slots 413 .

[0043] By adopting the above technical solution, the four limiting blocks 407 enter into the inside of the slot 413 under the relative movement of the limiting blocks 407, thereby completing the limiting and fixing of the second mounting plate 502.

[0044] Working principle: When in use, the upper expansion plate 102 and the lower expansion plate 101 in a closed state are inserted into the body, and after adjusting the position, the medical staff presses the top No. 1 control button 103 to start the first electric push rod 202, drive the push frame 203 to move upward, thereby driving the two tooth plates 205 to move upward. Since the first gear 206 is meshed and connected with the tooth plate 205, when the tooth plate 205 moves upward, it will drive the first gear 206 to rotate, and then drive the upper expansion plate 102 to rotate, so as to achieve the expansion effect during gynecological examination. When the appropriate expansion size is reached, the medical staff presses the top No. 1 control button 103 again to stop the first electric push rod 202 from extending and retracting, so that it remains in the current state; During inspection, the second control button 103 on the upper part can be pressed to start the second electric push rod 304, which drives the sliding plate 303 to slide on the upper part of the first slider 302, and at the same time drives the installation mechanism 4 and the clamping mechanism 5 installed on the upper part of the sliding plate 303 to move, and the transmission belt 306 to move. One side of the transmission belt 306 is fixedly installed on one side of the limit frame 309, so that when the transmission belt 306 is driven to move, it will cause the transmission belt 306 to rotate, so that one side of the driving block 402 on the upper part of the installation mechanism 4 is fixedly installed on the transmission belt 306. One side of the handle 1 drives the driving block 402 to move, that is, drives the mounting mechanism 4 and the clamping mechanism 5 to move, and when the first mounting plate 401 reaches the end of the second slider 305, the second electric push rod 304 stops working. At this time, the camera 403 on the upper part of the first mounting plate 401 is in the best position. At this time, the camera 403 and the lighting lamp 404 cooperate with each other to obtain the information about the internal body. The medical staff can observe the shooting situation of the camera 403 through the display 405 on the upper part of the handle 1, so as to facilitate the medical staff to obtain the information about the internal body; When sampling inspection is required, before inserting the expansion tool into the body, the second mounting plate 502 on which the clamping mechanism 5 is installed can be moved close to the lower part of the first mounting plate 401, and the double-headed screw 406 is driven by the first motor 412 to rotate, thereby driving the second bevel gear 411 to rotate, that is, since the first bevel gear 410 and the second bevel gear 411 are meshed and connected with each other, the two first bevel gears 410 are driven to rotate, thereby causing the two first screws 408 to rotate, and then the four limit blocks 407 are simultaneously moved toward the middle, so that the limit blocks 407 are clamped in the inside of the clamping groove 413, and then the second mounting plate 502 is fixed, that is, the installation of the clamping mechanism 5 is completed; By placing the handheld part of the sterile cotton swab for sampling in the middle of the two clamping frames 503, and pressing the third control button 103 at the bottom to start the third electric push rod 506, the two clamping frames 503 are moved relative to each other under the drive of the third electric push rod, so as to clamp and fix the sterile cotton swab. At this time, the outer surface of the sterile cotton swab is in contact with the outer surface of the electric roller 504. The process described in the first and second paragraphs of the above working principle is repeated, so that the sterile cotton swab is transported to a suitable position under the drive of the second electric push rod 304, so that the sampling end of the sterile cotton swab is in contact with the inner wall of the body; At this time, by pressing the fourth control button 103 at the bottom, the controller 505 receives the signal and sends a work instruction to each electric roller 504. After the electric roller 504 receives the start instruction, the internal motor is powered on, and the three-phase alternating current in the stator winding generates a rotating magnetic field, causing the rotor to start rotating. The rotational motion of the motor rotor is transmitted to the roller shaft through a coupling or other transmission device, so that the roller shaft starts to rotate under the drive of the motor, that is, the sterile cotton swab in contact with it is driven to rotate under the friction force, and the sterile cotton swab is sampled by slowly rotating it. After the sampling is completed, the clamping mechanism 5 is driven to move outward under the drive of the second electric push rod 304, so that the staff can take out the cotton swab after sampling.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
