DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-Figure 7 The present invention provides a technical solution: a gynecological and obstetric curettage, comprising a handle sleeve 1, one end of the handle sleeve 1 is fixedly connected to a connecting sleeve 2; a scraping rod 3 is connected to the connecting sleeve 2, one end of the scraping rod 3 is fixedly connected to the connecting sleeve 2, and the other end of the scraping rod 3 is fixedly connected to an arc-shaped guide rod 4; the arc-shaped guide rod 4 penetrates the connecting sleeve 2 and the handle sleeve 1, and a part of the arc-shaped guide rod 4 is located inside the handle sleeve 1; specifically, an arc-shaped limiting hole 21 is provided on the connecting sleeve 2 to match the arc-shaped guide rod 4, and a circular hole structure is provided on the handle sleeve 1 to match the arc-shaped guide rod 4, and the arc-shaped guide rod 4 passes through the circular hole and the arc-shaped limiting hole 21.

[0029] An arc motion mechanism 5 is provided on the handle sleeve 1 , and the arc motion mechanism 5 is used to drive the arc guide rod 4 to move in an arc, specifically, to drive the arc guide rod 4 to move around the center of the center line of the arc guide rod 4 .

[0030] The scraper rod 3 includes an arc-shaped spiral section 31, which is a spiral rod structure, and the arc-shaped spiral section 31 is an arc shape as a whole; a connecting section 34 is connected between one end of the arc-shaped spiral section 31 and the connecting sleeve 2, and the connecting section 34 is a cylindrical structure; the scraper rod 3 also includes an arc section 32, and a transition section 33 is connected between one end of the arc section 32 and the other end of the arc-shaped spiral section 31, and the arc section 32 is an arc rod structure. The arc section 32 and the transition section 33 are both arc rod structures, and the end of the arc section 32 away from the transition section 33 is fixedly connected to the arc guide rod 4, that is, the scraper rod 3 is formed by splicing the connecting section 34, the arc-shaped spiral section 31, the transition section 33 and the arc section 32 in sequence.

[0031] like Figure 3 As shown, the arc-shaped spiral segment 31 as a whole protrudes toward the left, while the circular arc segment 32 protrudes toward the right, that is, the protruding directions of the arc-shaped spiral segment 31 and the circular arc segment 32 are opposite.

[0032] The scraper rod 3 as a whole can be elastically deformed. Specifically, the arc-shaped spiral section 31 is made of a metal material with good elastic properties, such as nickel-titanium memory alloy, while the connecting section 34, the arc section 32 and the transition section 33 can all be made of stainless steel or alloy; in addition, the arc-shaped guide rod 4 is also made of stainless steel or alloy.

[0033] The arc motion mechanism 5 includes an arc-shaped slide rail 51 arranged inside the handle sleeve 1, and an arc-shaped slider 52 is provided on the arc-shaped slide rail 51. The end of the arc-shaped guide rod 4 away from the arc section 32 is fixedly connected to the arc-shaped slider 52; the center of the center line of the arc-shaped guide rod 4 coincides with the axis of the arc-shaped slider 52, that is, the axis of the inner annular surface of the arc-shaped slider 52 and the axis of the outer annular surface of the arc-shaped slider 52 both coincide with the center of the center line of the arc-shaped guide rod 4; when the arc-shaped slider 52 moves along the arc-shaped slide rail 51, the arc-shaped slider 52 moves in an arc around its own axis, thereby ensuring that the arc-shaped guide rod 4 moves around the axis of the arc-shaped slider 52; the arc motion mechanism 5 also includes a driving component 53, which is used to drive the arc-shaped slider 52 to move along the arc-shaped slide rail 51.

[0034] The driving assembly 53 includes a connecting rod 532 and a driving rod 531. One end of the connecting rod 532 is hinged on the arc-shaped slider 52, and the other end of the connecting rod 532 is hinged to one end of the driving rod 531. The other end of the driving rod 531 is movably set on the handle sleeve 1 through a rotating shaft. Specifically, the handle sleeve 1 is usually movably connected to the rotating shaft with a bearing, and the driving rod 531 is fixedly sleeved on the outside of the rotating shaft; the circular motion mechanism 5 also includes a reset assembly 54, which is used to reset the driving rod 531.

[0035] The driving assembly 53 further includes a pressing rod 533, which is fixedly arranged on one side of the driving rod 531; at the same time, an opening 11 is provided on the handle sleeve 1, such as Figure 2 As shown, in the initial state, the pressing rod 533 , the driving rod 531 and the connecting rod 532 all pass through the opening 11 .

[0036] When the pressing rod 533 is released, the driving rod 531 is reset under the action of the reset component 54, thereby realizing the reset of the arc slider 52 and the arc guide rod 4. When the arc guide rod 4 is reset, the scraper 3 can be restored to its original state. Figure 3 Status shown.

[0037] In the embodiment, when using the curettage, the vagina and cervix are first dilated by external medical instruments. After the dilation is completed, the handle sleeve 1 is held and the pressing rod 533 is pressed until the end of the pressing rod 533 hits the outer wall of the arc-shaped slide rail 51. At this time, the arc-shaped slide rail 51 blocks the pressing rod 533. Then, the deformed scraper rod 3 is extended into the uterus, and the pressing rod 533, the connecting rod 532 and other parts are now outside the patient's body. Then, the pressing rod 533 is released, and under the action of the reset assembly 54, the arc-shaped slide block 52 and the arc-shaped slide block 51 are reset. The guide rod 4 is reset, and the scraping rod 3 returns to its original state. With the assistance of external visual equipment, the protruding side of the arc-shaped spiral segment 31 is pressed against the inner wall of the uterus. By operating the handle sleeve 1, the arc-shaped spiral segment 31 scrapes the endometrial tissue. During the scraping process, the pressing rod 533 is repeatedly pressed and released with appropriate force. During the process of stretching and deforming or shortening and resetting, the arc-shaped spiral segment 31 has a scraping effect in both the horizontal and vertical directions, thereby improving the scraping efficiency of the arc-shaped spiral segment 31.

[0038] At the same time, the arc-shaped spiral segment 31, the circular arc segment 32, the transition segment 33, etc. are all rod-shaped structures, that is, the overall surface of the scraper 3 is smooth, and the arc-shaped spiral segment 31 can be elastically deformed. Therefore, under the premise of meeting a good scraping effect, it can effectively reduce damage to the uterus; after the embryo is hung, the curettage and the embryo can be taken out. During the process of removing the curettage, keep pressing the pressing rod 533 and make the end of the pressing rod 533 contact the arc-shaped slide rail 51, so as to facilitate the removal of the curettage; in addition, after the embryo is removed, the uterus can be cleaned up with subsequent residuals in conjunction with external suction equipment.

[0039] Example 2

[0040] See again Figure 2 、 Figure 3 as well as Figure 4, a plurality of through holes 311 are provided through the arc-shaped spiral segment 31, and a long hole 321 is provided through the circular arc segment 32. The penetration direction of the through hole 311 is consistent with the penetration direction of the long hole 321; the penetration direction of the through hole 311 is horizontal, and the axis direction of the through hole 311 is also horizontal; that is, Figure 3 As shown, the penetration direction of the through hole 311 is the left-right direction; and the edges of the through hole 311 and the long hole 321 are chamfered. A plurality of through holes 311 are provided on the arc-shaped spiral segment 31. During the scraping process using the arc-shaped spiral segment 31, the scraping efficiency can be improved, thereby helping to shorten the operation time.

[0041] In addition, during the scraping process, when the arc-shaped spiral segment 31 is inconvenient to scrape the endometrial tissue, the handle sleeve 1 can also be operated so that the protruding side of the arc segment 32 touches the inner wall of the uterus; since the arc segment 32 is provided with a long hole 321, the scraping operation can also be performed using the protruding side of the arc segment 32; when using the arc segment 32, the pressing rod 533 can be kept pressed continuously or the pressing rod 533 can be not pressed continuously, that is, in this process, there is no need to repeatedly press and release the pressing rod 533; therefore, it is easy to meet different usage needs and facilitate the scraping of endometrial tissue.

[0042] Example 3

[0043] See Figure 2 and Figure 4 The present embodiment is based on the second embodiment, and the reset component 54 adopts a spring 541. The spring 541 is arranged between the driving rod 531 and the inner wall of one side of the handle sleeve 1. Specifically, one end of the spring 541 can be connected to the driving rod 531, and the other end of the spring 541 contacts the inner wall of the handle sleeve 1; when the pressing rod 533 is pressed, the driving rod 531 rotates, which can cause the spring 541 to compress and deform; when the pressure on the pressing rod 533 is released, under the action of the elastic deformation of the spring 541, it is easy to drive the driving rod 531 to reset, thereby facilitating the reset of the arc-shaped slider 52, the arc-shaped guide rod 4, etc.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
