Description

Technical Field

[0001] The utility model relates to a gynecological surgical instrument, in particular to a uterine cavity tissue suction component. Background Art

[0002] Samples of cervical and uterine tissue are typically obtained in one of three ways in the prior art: dilation and endometrial curettage, which is called D&C; suction with a small diameter tube without dilating the cervix, which is called aspiration; or by suction curettage. D&C and suction curettage can collect as much cervical or uterine material as desired, but require anesthesia. Suction with a small diameter tube usually does not require anesthesia, but does not obtain as much tissue as D&C. In order to obtain as much tissue as D&C, aspiration must use a large diameter tube, which requires anesthesia.

[0003] In the prior art, a curette is usually used to remove uterine cavity tissue during uterine curettage, or a suction tube is used for suction. However, these two operations are not efficient in uterine curettage during the operation, and there will be fragments that need to be expelled by the uterus itself, resulting in incomplete uterine curettage. At the same time, the efficiency of suction of uterine cavity tissue is low during the uterine curettage process, thereby reducing the speed of uterine curettage. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a uterine cavity tissue suction component.

[0005] The above-mentioned problem of the utility model is solved by the following technical solutions:

The head of the suction tube is provided with a suction hole through which the head of the scraper can extend. The head of the scraper is provided with a cleaning part. The scraper is provided with a guiding structure connected with the cleaning part.

[0007] By adopting the above technical solution, a guiding structure is provided on the scraper, and the scraped tissue is guided into the inside of the suction tube, thereby leaving space at the head of the scraper, so that the inner wall of the uterine cavity can be continuously cleaned.

[0008] The above technical solution is further configured as follows: the guide structure is a threaded guide groove arranged on the outer peripheral surface of the scraper.

[0009] Compared with other forms of guiding structures, the guiding path of the threaded guiding groove is relatively long, and can guide and store more tissues to meet the needs of one-time clearing of the uterine cavity.

[0010] The above technical solution is further configured as follows: the head of the scraper is configured as a curved arm, and the head can be retracted into the interior of the suction tube and rotated.

[0011] By adopting the above technical solution, the guiding speed of the uterine cavity tissue is improved through the rotation function and the threaded guide groove, thereby improving the efficiency of uterine cleaning.

[0012] The above technical solution is further configured as follows: the head of the scraper is provided with a scraping groove, the scraping groove radially penetrates the head of the scraper and is connected to the guide structure.

[0013] The above technical solution is further configured as follows: the guide structure further includes a drainage groove connected between the thread guide groove and the scraping groove.

[0014] By adopting the above technical solution, the scraped uterine cavity tissue can be guided as completely as possible and enter the suction tube, thereby improving the efficiency of uterine cleaning.

[0015] The above technical solution is further configured as follows: a connecting sleeve is provided at the tail of the suction tube, and a conduit is extended from the side of the connecting sleeve for connecting an external suction device.

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] The following embodiment discloses a uterine cavity tissue suction assembly.

[0030] Specific reference Figure 1 As shown, it includes an inner and outer sleeve-connected suction tube 100 and a scraper 200, the head of the suction tube 100 is provided with a suction hole 101 for the head of the scraper 200 to extend out, the head of the scraper 200 is provided with a cleaning part, and the scraper 200 is provided with a guiding structure connected with the cleaning part.

[0031] The above is the basic solution of this embodiment.

[0032] Specific reference Figure 1 As shown, the scraper 200 is located inside the suction tube 100, and the head can be extended to the outside of the suction hole 101 of the head of the suction tube 100. When in use, the clear part of the head of the scraper 200 scrapes the tissue in the uterine cavity, and the scraped tissue is attracted into the suction tube 100 through the suction hole 101, and enters into the guide structure to clean the inner wall of the uterine cavity.

[0033] In this embodiment, the guiding structure serves to guide the tissue scraped from the removal site into the interior of the suction tube 100 .

[0034] Preferably, the guiding structure is a threaded guiding groove 201 provided on the outer circumferential surface of the scraper 200 .

[0035] Compared with other forms of guiding structures, the guiding path of the threaded guiding groove 201 is relatively long, and can guide and store more tissues to meet the demand for one-time cleaning of the uterine cavity.

[0036] Specifically, in this embodiment, the head of the scraper 200 is configured as a curved arm 210, and the head can be retracted into the interior of the suction tube 100 and rotated.

[0037] Reference Figure 2 and Figure 3As shown, the head of the scraper 200 extends out of the suction tube 100 through the special structure of the curved arm 210. When cleaning the inner wall of the uterine cavity, the end of the curved arm 210 of the head of the scraper 200 contacts the inner wall of the uterine cavity and performs a scraping action to remove the tissue on the inner wall of the uterine cavity.

[0038] After scraping, the uterine cavity tissue adheres to the head of the scraper 200 and enters the threaded guide groove 201 on the scraper 200. The scraper 200 is retracted into the suction tube 100, and the scraper 200 is rotated. The tissue in the threaded guide groove 201 moves along the threaded guide groove 201 toward the tail of the suction tube 100, thereby leaving space at the head of the threaded guide groove 201. The scraper 200 can be extended to the outside of the suction tube 100 again to clean the inner wall of the uterine cavity.

[0039] Consistent with the prior art, in this embodiment, the head of the scraper 200 is provided with a scraping groove 211 , and the scraping groove 211 radially penetrates the head of the scraper 200 and is connected with the guide structure.

[0040] Since the scraping groove 211 is arranged at the bent arm 210 and the threaded guide groove 201 is located at the straight rod position of the scraper 200, it is necessary to drain the scraping groove 211 and the head of the threaded guide groove 201. The specific implementation method is as follows: the guiding structure also includes a drainage groove 212 connected between the threaded guide groove 201 and the scraping groove 211.

[0041] Preferably, in order to cooperate with the scraping direction of the scraper 200, in this embodiment, the drainage groove 212 can be set on the concave and convex surfaces of the curved arm 210. Usually, when the scraper 200 is used for scraping, the end is usually in contact with the inner wall of the uterine cavity, and the concave part faces the inner wall of the uterine cavity that needs to be scraped. The scraped tissue usually adheres to the concave surface of the curved arm 210, and part of the tissue will accumulate on the convex surface of the curved arm 210 through the scraping groove 211. Therefore, the drainage grooves 212 are set on both surfaces to ensure that as much tissue as possible is drained into the suction tube 100.

[0042] In this embodiment, a connecting sleeve 300 is provided at the tail of the suction tube 100 , and a conduit 310 is extended from the side of the connecting sleeve 300 for connecting to an external suction device.

[0043] Reference Figure 4 As shown, a catheter 310 is provided on the side of the connecting sleeve 300 so that it can be connected to an external suction device. The suction device provides suction to the inner cavity of the suction tube 100, accelerates the flow of the uterine cavity tissue inside the suction tube 100, and enables the scraped uterine cavity tissue to move quickly toward the inside of the suction tube 100 until the tail of the suction tube 100. At the same time, the head of the scraper 200 can always have space to accommodate the newly scraped uterine cavity tissue, thereby improving the suction efficiency and the cleaning efficiency.

[0044] In order to operate the scraper 200 , in this embodiment, the end of the connecting sleeve 300 is configured as a constriction 102 , and the tail of the scraper 200 is provided with a hand-holding portion 220 , and the hand-holding portion 220 can extend out of the constriction 102 of the connecting sleeve 300 .

[0045] The operator pulls and rotates the hand-held portion 220 to rotate the scraper 200, thereby cleaning the inner wall of the uterine cavity and guiding and collecting the scraped tissue.

[0046] Preferably, in this embodiment, the hand-holding portion 220 is a rod-shaped structure formed at the tail of the scraper 200 .

[0047] In order to enable the hand-held part 220 to pass through the constriction 102 and to reduce the gap as much as possible to avoid leakage of internal gas, in this embodiment, the shape of the hand-held part 220 matches the constriction 102.

[0048] In this embodiment, the necking 102 is configured to be O-shaped, and the hand-holding portion 220 is configured to be a cylindrical rod.

[0049] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
