Example 2
The present embodiment is different from embodiment 1 in that: as shown in fig. 3 and 4, two groups of rotary cutters 4 are arranged on the inner side of the rubber cover 3, and a drawing rod 23 extending along the length direction of the handle 10 is fixed at the bottom of the micro motor 6 inside the handle 10; a sliding groove 24 for the fixed rod 12 to move up and down is arranged on the elastic supporting rod 2 connected with the fixed rod 12, circular ring-shaped push plates 25 respectively attached to and contacted with the corresponding sides of the fixed rod 12 are fixed on the opposite surfaces of the turntables 41 of the two groups of rotary cutters 4, and the reverse transmission mechanism is positioned on the inner sides of the circular ring-shaped push plates 25; the feeding hose 14 is arranged outside the handle 10. The drawing and pulling rod 23 can drive the rotary cutters 4 to move up and down in the rubber cover 3, the rotation directions of the two groups of rotary cutters 4 are opposite, and tissues attached to the inner wall of the uterus sinking into the through hole 5 in one state can be scraped and cut reversely, so that complete scraping and cutting can be guaranteed; along with the movement of the rotary cutter 4, the annular push plate 25 can push the fixed rod 12 to move up and down along the sliding groove 24, so that the requirement that the reverse transmission mechanism moves along with the rotary cutter 4 is met; in order to prevent the feed hose 14 from being affected in view of the need for the pull rod 23 to be pulled in the handle 10, the feed hose 14 is provided outside the handle 10.
In this embodiment, the elastic strut 2 is made of memory metal. The rubber cover has certain strength, and can support the rubber cover 3, so that enough operating space can be provided for the rotary cutter 4; and they can take place certain deformation when receiving the extrusion force, and can resume the original state after the extrusion force disappears, convenient application.
In this embodiment, a thumb ring 26 is fixed to the tail end of the pull rod 23, a flange plate 27 is fixed to the tail end of the handle 10, and finger rings 28 are fixed to the flange plate 27 on the side opposite to the thumb ring 26 and located on two opposite sides of the handle 10. When the drawing device is used, an operator respectively extends the forefinger and the middle finger into the two finger rings 28 to buckle the flange plate 27, and then extends the thumb into the thumb lantern ring 26 to conveniently push and pull the drawing rod 23, so that the drawing device is convenient to use.
In this embodiment, a protection cylinder 30 surrounding the reverse transmission mechanism is fixed on one side of the turntable 41 facing the reverse transmission mechanism, and the annular push plate 25 is fixedly sleeved on the protection cylinder 30. The protective cylinder 30 can protect the reverse transmission mechanism and prevent the scraped endometrial tissue from entering the reverse transmission mechanism to influence the operation of the endometrial tissue; the annular push plate 25 is fixedly sleeved on the protective cylinder 30, so that the connection between the annular push plate 25 and the corresponding rotary disc 41 can be conveniently realized.
In this embodiment, a limit rib 29 is fixed to the drive shaft 7. In the process of pulling back the drawing rod 23, the limiting convex strip 29 can be propped against the bottom plate 1, so that the drawing rod 23 is prevented from continuously withdrawing, and the arc-shaped knife 43 can be prevented from scraping and cutting the bottom plate 1.
The rest is the same as example 1.
The specific application process of the gynecological uterine curettage treatment device is as follows:
an operator holds the handle 10 to slowly extend the uterine curettage head 20 into the uterus, controls the length of the uterine curettage head 20 extending into a human body with the length scale 17 as the standard, extrudes the inner wall of the uterus on the rubber cover 3, enables the elastic supporting rod 2 to be embedded into the rubber cover 3 and not to be cut by the arc-shaped knife 43, presses the tissues attached to the inner wall of the uterus into the through hole 5, starts the suction device 16, generates suction force to the inner cavity of the uterine curettage head 20 along the feeding hose 14, and enables the tissues to be curetted outside the through hole 5 on the uterine curettage head 20 to be sucked into the through hole 5; then the micro motor 6 is started to drive the driving shaft 7 to rotate, and after the driving shaft is driven by the reverse transmission mechanism, the driving auxiliary shaft 8 is driven to rotate in the reverse direction of the driving shaft 7, so that the arc-shaped knife 43 is swung by the pull rope 42 to rotate around the center of the corresponding turntable 41, the cutting edge of the arc-shaped knife 43 rotates along the inner wall of the rubber cover 3, the inner membrane tissue in the rotating range is scraped and cut off, the endometrium cannot be scraped, and the endometrium can be prevented from being punctured or scratched; if the tissue to be scraped is thick, the arc-shaped knife 43 cannot smoothly scrape and cut, and the reverse acting force of the thick tissue to the arc-shaped knife 43 can bend the corresponding pull rope 42, so that the arc-shaped knife 43 can contact less tissues to successfully scrape and cut the partial tissues, the process of slicing and cutting the thick tissue in a layered manner is realized, and the complete scraping and cutting is facilitated;
the scraped tissues enter the feeding hose 14 from the through hole 13 under the suction action of the suction device 16 and then are conveyed into the cut tissue collecting box 15 along the feeding hose 14 so as to be convenient for taking and use, because the inner wall of the uterus is attached to the outer surface of the rubber cover 3 and blocks the through hole 5, the inner cavity of the uterine curettage head 20 is closed, the scraped tissues cannot enter the uterus, no intrauterine foreign matter residue is caused, and the health condition of a patient is favorably maintained;
then the drawing rod 23 is pushed and pulled, the rotary cutter 4 can be driven to move up and down in the cavity of the uterine curettage head 20, the tissue sunk into the through hole 5 can be more completely curetted, and the tissue is cut by the rotary cutter 4 with opposite rotation direction, so that the tissue can be completely curetted; the handle 10 is rotated to drive the uterine curettage head 20 to rotate in the uterus, the uterine curettage operation can be carried out on the inner wall of the uterus of the part where the uterine curettage head 20 is located, the handle 10 is pushed and pulled forward and backward, the uterine curettage range of the uterine curettage head 20 can be expanded, and because the rotation directions of every two adjacent groups of rotary cutters 4 are opposite, tissues are sequentially subjected to curettage in two opposite directions, and the completeness of curettage of the tissues is facilitated.
The invention has the advantages of good scraping completeness to the tissue, no puncture or scratch to the endometrium, no intrauterine foreign matter residue and being beneficial to maintaining the health condition of the patient.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
