Description

Technical Field

[0001] The invention relates to the technical field of gynecological surgical instruments, in particular to a gynecological ring remover for clinical use by gynecologists. Background Art

[0002] The ring removal forceps is a gynecological surgical instrument, mainly used for gynecological removal of IUDs. The main components include the head, rod, handle, and spring; the head includes upper and lower clamps, the rod includes upper and lower rods, and the handle includes front and rear handles. The ring removal forceps can directly reach the bottom of the uterus. And because the ring removal forceps have a round, blunt and smooth head, it is not easy to cause uterine perforation and damage to the organ. The top of the ring removal forceps is about 2cm long and has teeth, which is convenient for clamping the IUD, and is particularly suitable for removing broken, residual, and partially incarcerated IUDs.

[0003] Existing gynecologists use gynecological ring removers in clinical practice, but these are usually fixed-angle tools without angle adjustment function. Since the position and shape of the uterus of each patient are different, especially in the case of retroposition or anterior position of the uterus, the fixed tool angle may not be able to adapt to these differences, making it difficult for doctors to find the best operation path, thereby increasing the risk of accidentally damaging the uterine wall or other surrounding tissues. At the same time, an inappropriate tool angle may cause unnecessary pressure or pulling on the cervix and uterus during the operation, which will increase the patient's pain and discomfort. In addition, if the operation time is prolonged, the patient's anxiety and tension will also increase. Therefore, the existing gynecological and obstetric ring removers used clinically by obstetricians and gynecologists need to be improved to a certain extent. Summary of the invention

[0026] Working principle: When using the gynecological and obstetric ring remover for clinical use by gynecologists, first understand the patient's menstrual cycle, the time of the last menstrual period, whether there are any discomfort symptoms and other information, then perform a gynecological examination, evaluate the position and size of the uterus and the condition of the cervix, then insert the dilator into the vagina, and then insert the ring removal rod 3 through the dilator into the patient's vagina. At this time, the control switch 2 set on the outer wall of the handle 1 is used to start the No. 1 motor 405, so that the No. 1 motor 405 drives the adjustment plate 407 to rotate through the driving rod 406, so that the adjustment plate 407 pushes the adjustment rod 409 through the arc-shaped push groove 408, and then the adjustment rod 409 slides along the slide groove 404 opened through the top of the adjustment disk 402; At the same time, the adjusting rod 409 pushes the connecting rod 410, and the connecting rod 410 extends along the sliding hole 403 provided on the outer wall of the adjusting disk 402, so that the connecting rod 410 drives the expansion plate 411 to be adjusted synchronously, and the secondary expansion of the patient's vagina is completed, so as to increase the working range of the subsequent detector 27 and the clamping jaws 31 for angle adjustment and opening and closing, and prevent the clamping jaws 31 from contacting the inside of the vagina when adjusting. Since the clamping jaws 31 are in an open and closed state, the detector 27 is not blocked at this time and the inside of the vagina can be explored; At the same time, the control switch 2 is coordinated to drive the second motor 6 to work, so that the second motor 6 drives the first worm wheel 8 to rotate through the first worm 7, so that the first worm wheel 8 drives the first bevel gear 11 to rotate synchronously through the transmission rod 9. Since the first bevel gear 11 is meshed and connected with the second bevel gear 12, the fixed rod 13 follows the first bevel gear 11 for synchronous adjustment. At this time, the fixed rod 13 drives the mounting plate 16 to adjust the angle through the first push rod 14 fixed on the outer wall, so that the mounting plate 16 drives the support plate 15 to slide along the outer wall of the fixed rod 13, thereby driving the second protective shell 23, the second push rod 26 and the clamping claw 31 to adjust the angle synchronously through the mounting plate 16; Then, the third motor 17 is started in coordination with the control switch 2. At this time, the third motor 17 drives the second worm gear 19 to rotate through the second worm 18, so that the second worm gear 19 drives the fixed sleeve 20 to rotate along the limit frame 21, thereby driving the adjustment frame 22 to rotate through the fixed sleeve 20, and then the adjustment frame 22 drives the mounting plate 16 to rotate through the fixed rod 13 and the support plate 15, so that the second push rod 26 is driven to conduct a comprehensive survey of the patient's vagina through the 360-degree rotation and angle adjustment of the mounting plate 16. At this time, the survey data is transmitted to the survey screen on the display in real time through the transmission device, and the precise positioning of the contraceptive ring position is completed; Then, the cylinder 25 set in the No. 2 protective shell 23 is started by controlling the switch 2. At this time, the cylinder 25 drives the No. 2 push rod 26 to be raised and lowered, so that the No. 2 push rod 26 drives the push ring 28 fixed on the outer wall to be adjusted synchronously. Since the inner wall bearing of the connecting plate 29 is connected with the adjusting arm 30 and the push ring 28, the connecting plate 29 drives the adjusting arm 30 to rotate along the bearing frame 24 through the thrust of the push ring 28, and then the adjusting arm 30 drives the clamping claw 31 to close, completing the clamping of the contraceptive ring, and then drives the supporting mechanism assembly 4 to reset, so that the clamping claw 31 clamps the contraceptive ring and follows the ring removal rod 3 to take it out of the dilator, completing the ring removal for the patient.
