Detailed description of the invention
This induced abortion sweeping machine comprises negative pressure straw 1, handle 2 and negative pressure suction nozzle 3. On negative pressure straw 1, be provided with handle 2, on the axial circumference of negative pressure straw 1 of handle 3 one sides, be evenly equipped with 4 T-shaped chutes 4, on the negative pressure straw 1 of T-shaped chute 4 terminations, one end, be provided with negative pressure suction nozzle 3, on negative pressure suction nozzle 3 circumference, be evenly equipped with negative pressure sucker, negative pressure sucker is communicated with the centre bore 5 of negative pressure straw 1. On the negative pressure straw 1 of T-shaped chute 4 other end terminations, be fixedly installed baffle ring 6, the object of baffle ring 6 is terminations of the T-shaped chute 4 of envelope. Stop up on the circumference that encircles 6 and be evenly equipped with the push-rod hole corresponding with T-shaped chute 4 quantity.
On the negative pressure straw 1 of baffle ring 6 one sides, be movably set with and promote ring 7. The interior slide block 8 that is slidably fitted with respectively of each T-shaped chute 4; In T-shaped chute 4 between slide block 8 and negative pressure suction nozzle 3, be provided with scraping blade. Scraping blade is made up of scraping blade A9, scraping blade B10 and scraping blade C11; Scraping blade A9, scraping blade B10 and scraping blade C11 are flexibly connected by pin each other. Scraping blade A9 is support chip, can be 90 degree around negative pressure suction nozzle 3 and rotate, and scraping blade B10 is brace. Scraping blade is made up of elastomeric material, is provided with and scrapes sword on scraping blade. One end of scraping blade is connected with negative pressure suction nozzle 3 by pin; The other end of scraping blade is connected with slide block 8 by pin.
In the push-rod hole of baffle ring 6, be provided with push rod 12, one end of push rod 12 is connected with slide block 8; The other end of push rod 12 is connected with promotion ring 7. Promote screw thread on the negative pressure straw 1 between ring 7 and handle 2 promotion nut 13 is installed, promote nut 13 and be connected with 7 contacts of promotion ring.
On the negative pressure straw 1 of this induced abortion sweeping machine and push rod 12, be respectively arranged with scale value. To control the insertion depth of this sweeping machine entirety and to grasp scraping blade the size that struts shape in operation.
When this induced abortion sweeping machine work, scraping blade is contraction state, this sweeping machine entirety in a tubular form, be inserted into behind uterus according to the scale value on negative pressure straw 1, promote nut 13 by rotation, make its by promotion encircle 7, push rod 12 and slide block 8 promote scraping blade and progressively strut to become with uterine cavity shape matches and fall pyriform. Pregnant woman uterus in the time of 42-50 days is spherical in shape, and anteroposterior diameter is approximately consistent, and uterus combines and is down pyriform with uterine neck, and scraping blade is down pyriform after strutting, and just in time matches with uterine cavity shape. Then rotate negative pressure straw 1 by handle 2, can drive scraping blade to carry out dilatation and curettage operation. After dilatation and curettage has operated, rotate backward and promote nut 13 it is retreated, thereby then pull and promote ring and 7 drive scraping blade to be contracted to T-shaped chute 4 by push rod 12 and slide block 8, it is reduced in a tubular form, then adsorb cleaning by negative pressure suction nozzle 3 to scraping the intrauterine tissue of cutting, accuse and performed the operation. In this sweeping machine surgical procedure, because uterine smooth muscle is to tractive sensitivity, can produce pain, cut insensitively to scraping, can not produce pain; Therefore this sweeping machine first scrape in the operating process of cutting rear absorption patient there will not be pain, leak inhale, organ damage, and the situation of the perforation of uterus. This sweeping machine has easy to use, and the feature that operating time is short has solved conventional abortion and not only will use negative pressure straw, also to use probe, cause the painful large problem of corrective surgery, and while adopting balanced anesthesia, can make patient's unconsciousness produce the problem of various disadvantages; Being specially adapted to artificial abortion operation uses.
