Problems solved by technology

[0003] Common curettage devices generally include vaginal dilation forceps, cervical dilation rods and scraping devices. The vaginal dilation forceps need to be placed on the vulva, and the vulva and vagina are stretched apart by controlling the relative distance between the two support plates to provide Larger operating space, after the completion of vaginal dilation, due to the need to scrape the contents of the uterus, and there is a cervix between the end of the vagina and the uterus, and the cervix in a normal state cannot allow the scraping device to pass through, so after vaginal dilation Medical personnel also need to insert the cervical dilation rod into the inside of the cervix through the vagina for expansion operation. Due to the step-by-step operation and two independent devices, it is very easy to cause vaginal bleeding due to vaginal damage during the operation, and the step-by-step operation state It can also cause unnecessary discomfort
[0004] In dilatation and curettage, before scraping the contents of the uterus, the cervix and cervical opening need to be stretched to allow the negative pressure suction tube and scraping device to enter. Since the cervix is ​​at the back end of the vagina and its operating space is limited, so In the prior art, cervical dilatation rods with small to large specifications are used to enter the interior of the cervix in order to gradually expand the cervix. The whole process requires the use of three to four cervical dilation rods, and each time The process of inserting the cervical dilator will cause significant discomfort to the patient, and in severe cases, it will cause severe damage to the cervix and affect reproductive function

[0044] When the movable block 1 is displaced downward, at this time, since the slider 8 can only relatively slide inside the guide rail 2, and the overall length of the connecting rod 7 does not change, when the movable block 1 is displaced downward, the connecting rod 7 is It can be deflected to the outside to drive the slider 8 to move relative to the guide rail 2. At this time, the two second fixing bases 6 can be relatively far away, and the two mounting rods 9 can be moved away from each other, and the mounting rod 9 can push the support plate 10 to be relatively When the movable block 1 moves downwards, it drives the extension rod 11 to move downwards to drive the piston plate 16 to move downwards, thereby compressing the alcohol between the piston plate 16 and the expansion device 18. The volume of alcohol is fixed. When one end of the alcohol is stressed, it can directly push the expansion device 18 to move outward, and at this time, one end of the expansion device 18 c...

[0052] When the expansion device 18 is displaced to the outside under the action of alcohol, if the bottom end of the limiting plate 183 touches the bottom end of the inner cavity of the liquid storage tank 12, at this time, the piston plate 16 continues to face the interior of the liquid storage tank 12. The alcohol is compressed, and the expansion device 18 cannot continue to move to the outside. At this time, the pressure of the alcohol can act on the one-way flap valve 184, continuously apply pressure to the one-way flap valve 184 and open the one-way flap valve 184. At this time The alcohol can enter the limiting plate 183 through the one-way flap valve 184 and enter the interior of the expansion tube 182, and as the alcohol enters, it will enter the interior of the rubber hose 186 through the output port 185. At this time, the soft rubber is made of soft rubber. The tube 186 can be compressed and expanded. At this time, the length of the entire rubber hose 186 will increa...

[0055] When the dilation of the vagina and cervix is ​​completed, the contents of the uterus can be scraped and suctioned by negative pressure. After the whole operation is completed, the solenoid valve 187 can be opened directly. At this time, the alcohol inside the rubber hose 186 can pass through the solenoid valve 187 Enter the inside of the uterus and cervix and the inside of the vagina, and then rinse the contents and scraping residues. After washing, it can be sucked out through a negative pressure device to complete the curettage process.

[0056] By using alcohol to directly act on the disinfection operation after the curettage operation, at the same time, the flow of alcohol can drive the scraping residue and the content to flow out, so as to avoid the infection caused by the residue during scraping. It has been heated before entering the dilation device 18, so it will significantly reduce the discomfort of the patient. At the same time, the alcohol in the flushing pr...

Abstract

The invention belongs to the technical field of gynaecology and obstetrics, and discloses a gynaecology and obstetrics uterine curettage device which comprises a movable block, a guide rail is arranged below the movable block, first fixing seats are fixedly mounted on the left side and the right side of the bottom end of the movable block, supporting plates are arranged on the left side and the right side of a mounting rod, and a liquid storage tank is fixedly mounted at the bottom end of the mounting rod. And the bottom end of the liquid storage tank fixedly communicates with a limiting pipe. According to the cervical dilator, the piston plate is driven to displace and compress the alcohol while the supporting plate dilates the vagina, the dilation device is directly pushed to displace by utilizing the pressure provided when the alcohol is compressed, so that the dilation device is inserted into the cervix uteri so as to perform subsequent cervical dilation, and a power source and power during vagina dilation are utilized, so that the cervical dilation effect is greatly improved. The vagina dilator is simple in structure and convenient to operate, secondary injury caused by step-by-step operation when a traditional device firstly dilates the vagina and then dilates the cervix uteri is avoided, vagina dilation and cervix uteri dilation are carried out at the same time, secondary injury is avoided, operation steps are simplified, and operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of obstetrics and gynecology, in particular to a curettage device for obstetrics and gynecology. Background technique [0002] Dilation and curettage refers to the operation of scraping the contents of the uterine lining or uterine cavity, and it is one of the methods of artificial abortion. Divided into diagnostic curettage (referred to as curettage) and therapeutic curettage. There are certain risks and complications. The curettage is divided into general curettage and segmented curettage. General diagnosis and curettage, suitable for endocrine abnormalities, need to understand endometrial changes and the response to sex hormones, with or without ovulation, with or without tuberculosis embolism. In segmented diagnosis and curettage, the cervical canal is first scraped and then the uterine cavity is scraped, and the scraped objects are sent for pathological examination respectively. It is suitable for di...
